The optimal wrist position between extension and flexion to achieve the highest grip strength, was assessed on the dominant hand of 20 normal female subjects aged 18–25. Seven fixed wrist positions between 60 degrees flexion and 60 degrees extension were assessed as well as a “self selected” position which was chosen by the subjects. Other variables were recorded and analyzed such as hand length, wrist circumference, height and weight of the subjects. Grip strength was recorded using an electrodynamometer. The mean self selected angle was 28 degrees wrist extension, and this position had the highest mean strength of all angles tested. The self selected angle was positively correlated with hand length. Grip strength decreased dramatically in marked wrist flexion compared to extension. The self selected wrist position increased with hand length, height, and weight

Purpose. Handgrip dynamometry has previously been used to detect pre - operative malnutrition and predict the likelihood of post - operative complications. This study explored whether a relationship exists between pre-operative pinch and power grip strength and length of hospital stay in patients undergoing hip and knee arthroplasty. We investigated whether handgrip dynamometry could be used pre - operatively to identify patients at greater risk of longer inpatient stays. Methods. 164 patients (64 male, 100 female) due to undergo lower limb arthroplasty (83 Total Knee Replacement, 81 Total Hip Replacement) were assessed in pre - admission clinic. Average measurements of pinch grip and power grip were taken from each patient using the Jamar hydraulic dynamometer (Jamar, USA). Duration of each inpatient stay was recorded. Patients with painful or disabling conditions involving the upper limb were excluded. Other clinical variables such as age and ASA grade were investigated as potential confounders of the relationship of interest and adjusted for. Results. Average duration of hospital stay was 9.4 days. Average pinch grip was 6.3kg, average power grip 25.4 kg. Both average pinch grip strength (p = 0.001) and average power grip strength (p=0.04) had a significant negative correlation with duration of inpatient stay. Patients with a pinch grip strength less than 6.3kg remained in hospital 2 days longer on average. Patients with a power grip strength less than 15kg remained in hospital 1.6 days longer on average. Conclusions. This study demonstrated a clear relationship between pre - operative grip strength and length of hospital admission in these patients. This simple test may be beneficial pre - operatively in identifying those patients likely to require longer inpatient stays and therefore those who would benefit from early nutritional intervention and focussed physiotherapy. We believe this may effect significant cost reductions in the NHS

Introduction. Closed avulsion of the Flexor Digitorum Profundus (FDP) from distal phalanx most commonly affects the ring finger when an extensive force is applied to a finger in active flexion. Whilst it is undoubtably reasonable to provide treatment for those who present with symptoms, there may be a cohort of people who sustain an avulsion without noticing. This study aims to quantify the effect of ring finger FDP avulsion on overall grip strength to determine the functional effect of a missed injury. Method. Right handed volunteers, with no abnormality on examination were included (N= 42). Proximal muscle group action was excluded. Grip strength was tested using a Jamar dynamometer with and without splinting of the ring finger to block flexion at the DIPJ and repeated six times alternately to mitigate the effects of fatigue. Results. Most subjects showed a small (0.3–3kg) change in their average grip strength with the splint (N= 29). Some showed a dramatic change in their grip strength (6–11.4) (N=6) others showed no change or slight improvement with the splint (−3–0) (N=7). Data were not normally distributed (kolmogorov-smirnov p=0.023). A wilcoxon signed rank test showed a statistically significant difference in performance with, compared to without, the splint, mean 2.34kg reduction (−3.3 − 11.4) (p <0.0005. Discussion. Horton et al have examined the quadriga effect and shown that the individual strength of other digits is reduced when one FDP is isolated. This implies overall grip strength should be reduced; our data supports this assertion. However despite splinting, the majority of subjects were still within the normal range of power for age. Larger scale studies are required to assess the functional effect of repair vs conservative management

To assess the effect of deformity on Grip strength characteristics in the Rheumatoid Hands using force time curves. Forty seven (6 males and 41 females) patients with mean age 62 years (29–79 yrs) with Rheumatoid arthritis had their handgrip strength measured with closed fluid dynamometer generating force-time curves. These were analysed further in blinded fashion for:. peak force;. average force;. time to peak. and variance of the force data through the plateau region (final 60% of curve). Data was also collected on joint mobility, pain and disability using Patient Evaluation Measure (PEM) and Functional Disability Scores (FDS). The patients were divided into five groups according to the degree of deformity: No deformity, ulnar deviation, Boutonniere, Swan neck or combined deformities (two or more deformities). These patient groups showed significant differences in grip strength (p value < 0.01). Patients with combination of deformities showed low peak and average forces as measured on force-time curves. The hands with Swan neck deformities had the highest variability in the plateau region of the curve and had the greatest disability scores both with PEM and FDS scores (P Value < 0.005). This group was particularly disabled (P Value < 0.007) being less able to sustain the grip over time. Swan Neck Deformity causes the most significant dysfunction and this should be carefully considered when making decisions regarding surgery

Aims. Patients with a triangular fibrocartilage complex (TFCC) injury report ulnar-sided wrist pain and impaired function. The surgical procedure of TFCC reinsertion aims to improve function in patients with this injury in whom conservative treatment has failed. The purpose of this study was to investigate the outcomes of open TFCC reinsertion. Methods. The study involved 274 patients who underwent open repair of the TFCC between December 2013 and December 2018. The patients completed the Patient-Rated Wrist Evaluation (PRWE) questionnaire, and scored pain and function using a visual analogue scale (VAS). Range of motion (ROM) was assessed by experienced hand therapists. Results. Clinically significant improvements were reported in pain, function, and grip strength in 220 patients (80%) three and 12 months postoperatively. Conclusion. These data will help surgeons to make decisions about the outcomes of open repair of the TFCC and to counsel patients appropriately. Level of evidence: III.

Aims

We conducted a study to determine whether radiological parameters correlate with patient reported functional outcome, health-related quality of life and physical measures of function in patients with a fracture of the distal radius.

Aims. This study aims to report the outcomes in the treatment of unstable proximal third scaphoid nonunions with arthroscopic curettage, non-vascularized bone grafting, and percutaneous fixation. Methods. This was a retrospective analysis of 20 patients. All cases were delayed presentations (n = 15) or failed nonoperatively managed scaphoid fractures (n = 5). Surgery was performed at a mean duration of 27 months (7 to 120) following injury with arthroscopic debridement and arthroscopic iliac crest autograft. Fracture fixation was performed percutaneously with Kirschner (K)-wires in 12 wrists, a headless screw in six, and a combination of a headless screw and single K-wire in two. Clinical outcomes were assessed using grip strength, patient-reported outcome measures, and wrist range of motion (ROM) measurements. Results. Intraoperatively, established avascular necrosis of the proximal fragment was identified in ten scaphoids. All fractures united within 16 weeks, confirmed by CT. At a mean follow-up of 31 months (12 to 64), there were significant improvements in the Patient-Rated Wrist Evaluation, Mayo Wrist Score, abbreviated Disabilities of the Arm, Shoulder and Hand score, wrist ROM, grip strength, and the patients’ subjective pain score. No peri- or postoperative complications were encountered. Conclusion. Our data indicate that arthroscopic bone grafting and fixation with cancellous autograft is a viable method in the treatment of proximal third scaphoid nonunions, regardless of the vascularity of the proximal fragment.

There is no consensus for the appropriate surgical management of chronic ulnar collateral ligament (UCL) injuries of the thumb. A systematic review of Pubmed, MEDLINE, EMBASE and ePub Ahead of Print was performed in accordance with Preferred Reporting of Items in Systematic Review and Meta-analysis (PRISMA) guidelines and formal protocol registered with PROSPERO. Two authors collated data from 10 studies that met strict inclusion criteria, using various surgical techniques in 131 thumbs. Results were heterogenous and metanalysis of results not possible. These data were, therefore, qualitatively assessed and synthesised. Bias was assessed using the ROBINS-I tool. Direct repair, reconstruction with free tendon or bone-tissue-bone grafts and arthrodesis all demonstrated favourable outcomes with Patient Reported Outcome Measures. Direct repair can be safely performed more than two months following injury, with a positive mean Disabilities of the Arm, Shoulder and Hand (DASH) score of 13.5 despite evidence of radiographic osteoarthritis. Arthrodesis should be considered in heavy manual laborers or those at risk of osteoarthritis as it provides significant reduction in pain (Mean Visual Analogue Score of 1.2) when compared to other methods. Free tendon grafting has been criticised for failure rates and poor functional grip strength, however collated analysis of 97 patients found a single graft rupture and mean grip strength of 97% (of the contralateral thumb). Bone-tissue-bone grafting was the least effective method across all outcome measures. Studies included were at high risk of bias, however, it can be concluded that delayed direct repair can be performed safely, while arthrodesis may benefit certain patient subgroups. New findings suggest poor efficacy of bone-tissue-bone grafts, but that free tendon grafting with palmaris longus are in fact safe with good restoration of grip strength. The optimal graft and configuration are yet to be determined for reconstructive methods

Aims. The aim of this study was to assess and compare active rotation of the forearm in normal subjects after the application of a short-arm cast (SAC) in the semisupination position and a long-arm cast (LAC) in the neutral position. A clinical study was also conducted to compare the functional outcomes of using a SAC in the semisupination position with those of using a LAC in the neutral position in patients who underwent arthroscopic triangular fibrocartilage complex (TFCC) foveal repair. Methods. A total of 40 healthy right-handed volunteers were recruited. Active pronation and supination of the forearm were measured in each subject using a goniometer. In the retrospective clinical study, 40 patients who underwent arthroscopic foveal repair were included. The wrist was immobilized postoperatively using a SAC in the semisupination position (approximately 45°) in 16 patients and a LAC in 24. Clinical outcomes were assessed using grip strength and patient-reported outcomes. The degree of disability caused by cast immobilization was also evaluated when the cast was removed. Results. Supination was significantly more restricted with LACs than with SACs in the semisupination position in male and female patients (p < 0.001 for both). However, pronation was significantly more restricted with SACs in the semisupination position than with LACs in female patients (p = 0.003) and was not significantly different in male patients (p = 0.090). In the clinical study, both groups showed improvement in all parameters with significant differences in grip strength, visual analogue scale scores for pain, modified Mayo Wrist Score, the Disability of the Arm, Shoulder, and Hand (DASH) score, and the Patient-Rated Wrist Evaluation (PRWE) score. No significant postoperative differences were noted between LACs and SACs in the semisupination position. However, the disability caused by immobilization in a cast was significantly higher in patients who had a LAC on the dominant hand (p < 0.001). Conclusion. We found that a SAC in the semisupination position is as effective as a LAC in restricting pronation of the forearm. In addition, postoperative immobilization with a SAC in the semisupination position resulted in comparable pain scores and functional outcomes to immobilization with a LAC after TFCC foveal repair, with less restriction of daily activities. Therefore, we recommend that surgeons consider using a SAC in the semisupination position for postoperative immobilization following TFCC foveal repair for dorsal instability of the distal radioulnar joint.

Aims. The purpose was to evaluate early clinical, patient-reported, and radiological outcomes of the scapholunate ligament 360° tenodesis (SL 360) technique for treatment of scapholunate (SL) instability. Methods. We studied the results of nine patients (eight males and one female with a mean age of 44.7 years (26 to 55)) who underwent the SL 360 procedure for reducible SL instability between January 2016 and June 2019, and who were identified from retrospective review of electronic medical records. Final follow-up of any kind was a mean of 33.7 months (12.0 to 51.3). Clinical, radiological, and patient-reported outcome data included visual analogue scale (VAS) for pain, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), Mayo Wrist Score (MWS), and Patient-Rated Wrist Examination (PRWE). Means were analyzed using paired t-test. Results. Before surgery, patients with SL instability were significantly impaired with respect to wrist flexion, extension, and grip strength (mean flexion, 51° (20° to 85°) vs 73° (45° to 90°); mean extension, 46° (15° to 70°) vs 66° (45° to 80°); mean grip strength, 25 kg (20 to 31) vs 50 kg (35 to 68) compared to the unaffected side). The mean SL gap (4.9 mm (2.3 to 7.3) vs 2.1 mm (1.6 to 2.9)) and mean SL angle (71° (59° to 105°) vs 50° (38° to 64°) were also significantly greater in the affected wrist. At final follow-up, there was mean improvement regarding clinical, radiological, and functional outcomes comparing preoperative to final postoperative values for the VAS for pain scale, QuickDASH, MWS, PRWE, and SL gap and SL angle. Conclusion. In our small series, the SL 360 procedure for reducible SL instability has favourable early clinical, patient-reported, and radiological outcomes at a mean of 33.7 months (12.0 to 51.3). The suture tape and tendon construct confers robust stability, permitting earlier mobilization without the inherent disadvantages of Kirschner wire stabilization.

Introduction and Purpose. Metacarpal fractures constitute approximately one third of all hand fractures. The majority of these fractures are treated by conservative non-surgical methods. The aim of this study is to obtain the appropriate anatomical alignment of the fracture with dynamic metacarpal stabilization splint (DMSS) and to maintain the proper bone anatomy until the union is achieved. In addition, by comparing this method with short arm plaster splint (SAPS) application, it is aimed to evaluate whether patients are superior in terms of comfort, range of motion (ROM) and grip strength. Materials and Methods. In our study, SAPS or DMSS was applied to the patients with 5th metacarpal neck fracture randomly after fracture reduction and followed for 3 months. A total of 119 patients with appropriate criteria were included in the study. Radiological alignment of the fracture and amount of joint movements were evaluated during follow-up. Grip strength was evaluated with Jamar dynamometer. EQ-5D-5L and VAS scores were used for clinical evaluation. Results. 103 patients completed their follow-up. 51 patients were treated with SAPS and 52 patients were treated with DMSS. The mean age of the SAPS was 29.5 (SD ± 9.4; 16–53 years) and the mean age of the DMSS group was 27.8 (SD ± 11.6; 16–63). Pressure sores was seen in 5 patients in the DMSS group, while no pressure sore was seen in the SAPS (p = 0.008). There was no significant difference between the two groups in the VAS scores at all times. There was no significant difference between the mean dorsal cortical angulation (DCA) before the reduction, after the reduction and at the third month follow-ups. There was no statistically significant difference between the length of metacarps at first admittion before reduction, after reduction and at third month follow-ups. When the grip strength of the two groups were compared as a percentage, the grip strength of the patients in the DMSS group was found to be higher at 1st month, 2nd month and 3rd month (p <0.001). When the ROM values of the patients were evaluated, DMSS group had a higher degree of ROM in the first month compared to the SAPS group (p <0.001). No statistically significant difference was detected among groups at third month in the ROM of the IP and MP joints. However, wrist ROM was statistically higher in DMSS group at 3rd month (p <0.05). There was a statistically significant difference between EuroQol scores in favor of DMSA group (p <0.05). Discussion and Conclusion. In stable 5th metacarpal neck fractures, DMSA is as effective as SAPS to maintain bone anatomy. In addition, DMSA can be preferred for fixation plaster splint or circular plaster applications for the prevention of reduction in boxer fractures, with the advantage of having high clinical scores, which is an indication of early acquisition of grip strength, ease of use and patient comfort

Aims. Fixation of scaphoid nonunion with a volar locking plate and cancellous bone grafting has been shown to be a successful technique in small series. Few mid- or long-term follow-up studies have been reported. The aim of this study was to report the mid-term radiological and functional outcome of plate fixation for scaphoid nonunion. Methods. Patients with a scaphoid nonunion were prospectively enrolled and treated with open reduction using a volar approach, debridement of the nonunion, and fixation using a locking plate and cancellous bone grafting, from the ipsilateral iliac crest. Follow-up included examination, functional assessment using the patient-rated wrist/hand evaluation (PRWHE), and multiplanar reformation CT scans at three-month intervals until union was confirmed. Results. A total of 49 patients with a mean age of 31 years (16 to 74) and a mean duration of nonunion of 3.6 years (0.4 to 16) were included. Postoperatively, the nonunion healed in 47 patients (96%) as shown on CT scans. The mean time to union was 4.2 months (3 to 12). Due to impingement of the plate on the volar rim of the radius and functional limitation, the hardware was removed in 18 patients. At a median follow-up of 38 months in 34 patients, the mean active range of motion (ROM) improved significantly from 89° to 124° (SD 44°; p = 0.003). The mean grip strength improved significantly from 52% to 79% (SD 28%; p < 0.001) of the contralateral side. The mean PRWHE score improved significantly from 66 to 17 points (SD 25; p < 0.001). Conclusion. Locking plate fixation supplemented with autologous cancellous bone grafting is a successful form of treatment for scaphoid nonunion. Functional outcomes improve with the passage of time, and mid-term results are excellent with a significant improvement in ROM, grip strength, and functional outcome as measured by the PRWHE.

Aims. The objective of this systematic review was to describe trapeziectomy outcomes and complications in the context of osteoarthritis of the base of the thumb after a five-year minimum follow-up. Methods. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to guide study design, and 267 full-text articles were assessed for eligibility. After exclusion criteria application, 22 studies were included, involving 728 patients and 823 trapeziectomies. Outcomes included pre- and postoperative clinical and radiological characteristics. Complications and revisions were recorded. Results. All the studies reported good results regarding pain and range of motion at the last follow-up of 8.3 years (5 to 22); the mean satisfaction rate was 91% (84% to 100%). It was difficult to assess the impact on metacarpophalangeal joint motion in extension with contrary results. The key pinch returned to its preoperative values, whereas tip pinch showed a modest improvement (+14%), with a mild improvement found in grip strength (+25%) at the last follow-up. The mean progressive trapezial collapse was 48% (0% to 85%) and was not correlated with pain, grip strength, or satisfaction. The most represented complications were linked to tendons or nerves affected during additional procedures to stabilize the joint (11.6%; n = 56). Mechanical complications included symptomatic scapho-M1 impingement (3.1%; n = 15/580), leading to nine surgical revisions out of 581 trapeziectomies. Meta-analysis was not possible due to study heterogeneity and limited data. Conclusion. After a minimum five-year follow-up, trapeziectomy achieved high patient satisfaction and pain relief. However, strength seemed to be deteriorating with detrimental consequences, but this did not correlate with trapezial collapse. The issues related to underestimating mechanical complications and varying degrees of success should be highlighted in the information given to patients. Evidence-based analyses should help the surgeon in their decision-making. Cite this article: Bone Jt Open 2021;2(3):141–149

The trapeziometacarpal joint (TMCJ) is the most common hand joint affected by osteoarthritis (OA), and trapezium implant arthroplasty is a potential treatment for recalcitrant OA. This meta-analysis aimed to investigate the efficacy and safety of various trapezium implants as an interventional option for TMCJ OA. Web of Science, PubMed, Scopus, Google Scholar, and Cochrane library databases were searched for relevant studies up to May 2022. Preferred Reported Items for Systematic Review and Meta-Analysis guidelines were adhered to and registered on PROSPERO. The methodological quality was assessed by National Heart, Lung, and Blood Institute tools for observational studies and the Cochrane risk of bias tool. Subgroup analyses were performed on different replacement implants, the analysis was done via Open Meta-Analyst software and P values < 0.05 were considered statistically significant. A total of 123 studies comprising 5752 patients were included. Total joint replacement (TJR) implants demonstrate greater significant improvements in visual analogue scale pain scores postoperatively. Interposition with partial trapezial resection implants was associated with the highest grip strength and highest reduction in the Disabilities of the Arm, Shoulder, and Hand score. Revision rates were highest in TJR (12.3%), and lowest in interposition with partial trapezial resection (6.2%). Total joint replacement and interposition with partial trapezial resection implants improve pain, grip strength, and DASH scores more than other implant options. Future studies should focus on high-quality randomized clinical trials comparing different implants to accumulate higher quality evidence and more reliable conclusions

Abstract. Background. We know that tears of the Triangular fibrocartilage complex (TFCC) can cause DRUJ instability and ulnar sided wrist pain. This study shows the clinical result of patients who had arthroscopic transosseous repair of the TFCC tear with DRUJ instability. Arthroscopic repair of TFCC tear is a promising, minimally invasive surgical technique especially in patients with DRUJ instability. Materials and methods. Fifteen patients who underwent TFCC one tunnel repair form 2018–2021 were reviewed retrospectively in hospital. The proximal component of TFCC was repaired through arthroscopic one- tunnel transosseous suture technique. VAS score for pain, wrist range of motion, grip strength and post operative complications were evaluated and each patient was rated according to the DASH score. Results. The patients had a TFCC tear confirmed on MRI and was confirmed on arthroscopy by doing a hook test. The patients were followed up for 6 months. Twelve patients had normal stability of DRUJ and three patients showed mild laxity compared with the contralateral side. The mean VAS score reduced from 4.7 to 0.8 (P=0.001) and grip strength increased significantly. The quick DASH score (P=0.001)also showed significant functional improvement. No surgical related complications occurred. Conclusions. Arthroscopic one tunnel transosseous TFCC foveal repair can be an excellent and safe method for repair of TFCC tear with DRUJ instability. Its a good treatment option in terms of reliable pain relief, functional improvement and reestablishment of DRUJ stability

Distal radius fractures (DRF) are common and the indication for surgical treatment remain controversial in patients higher than 60 years old. The purpose of the study was to review and analyze the current evidence-based literature. We performed a systematic review and meta-analysis according to PRISMA guidelines in order to evaluate the efficacy of volar locking plating (VLP) and conservative treatment in DRF in patients over 60 years old. Electronic databases including MEDLINE, CENTRAL, Embase, Web of science and Clinical Trial.gov were searched from inception to October 2020 for randomized controlled trials. Relevant article reference lists were also passed over. Two reviewers independently screened and extracted the data. Main outcomes included functional status: wrist range of motion, validated scores and grip strength. Secondary outcomes include post-operative complications and radiologic assessment. From 3009 screened citations, 5 trials (539 patients) met the inclusion criteria. All trials of this random effect meta-analysis were at moderate risk of bias due to lack of blinding. Differences in the DASH score (MD −5,91; 95% CI, −8,83; −3,00), PRWE score (MD −9.07; 95% CI, −14.57, −3.57) and grip strength (MD 5,12; 95% CI, 0,59-9,65) were statistically significant and favored VLPs. No effect was observed in terms of range of motion. Adverse events are frequent in both treatment groups, reoperation rate is higher in the VLP group. VLP may provide better functional outcomes in patients higher than 60 years old. More RCT are still needed to evaluate if the risks and complications of VLP outweigh the benefits

Sarcopenia is an age-related geriatric syndrome which is associated with subsequent disability and morbidity. Currently there is no promising therapy approved for the treatment of sarcopenia. The receptor activator of nuclear factor NF-κB ligand (RANKL) and its receptor (RANK) are expressed in bone and skeletal muscle. Activation of the NF-κB pathway mainly inhibits myogenic differentiation, which leads to skeletal muscle dysfunction and loss. LYVE1 and CD206 positive macrophage has been reported to be associated with progressive impairment of skeletal muscle function with aging. The study aims to investigate the effects of an anti-RANKL treatment on sarcopenic skeletal muscle and explore the related mechanisms on muscle inflammation and the polarization status of macrophages. Sarcopenic senescence-accelerated mouse P8 (SAMP8) mice at month 8 were treated intraperitoneally with 5mg/kg anti-RANKL (IK22/5) or isotype control (2A3; Bio X Cell) antibody every 4 weeks and harvested at month 10. Senescence accelerated mouse resistant-1 (SAMR1) were collected at month 10 as the age-matched non-sarcopenic group. Ex-vivo functional assessment, grip strength and immunostaining of C/EBPa, CD206, F4/80, LYVE1 and PAX7 were performed. Data analysis was done with one-way ANOVA, and the significant level was set at p≤0.05. At month 10, tetanic force/specific tetanic force, twitch force/specific twitch force in anti-RANKL group were significantly higher than control group (all p<0.01). The mice in the anti-RANKL treatment group also showed significantly higher grip strength than Con group (p<0.001). The SAMP8 mice at month 10 expressed significantly more C/EBPa, CD206 and LYVE1 positive area than in SAMR1, while anti-RANKL treatment significantly decreased C/EBPa, CD206 and LYVE1 positive area. The anti-RANKL treatment protected against skeletal muscle dysfunctions through suppressing muscle inflammation and modulating M2 macrophages, which may represent a novel therapeutic approach for sarcopenia.

Introduction. Despite the rising popularity of 1st carpometacarpal joint (CMCJ) arthrodesis as one of the surgical options for basilar thumb arthritis, the available literature on this is poor. This study aims to investigate post-operative pinch and grip strength following 1st CMCJ arthrodesis, at a minimum of 1 year follow-up. Complication rates, range of motion and patient reported scores were also evaluated. Methods. A retrospective cohort (2012–2020) was used, which included patients who had arthrodesis performed by the Hands surgeons at Counties Manukau DHB. In a 15 minute visit, we took the measurements using our standard dynamometer and pinch gauge, and collected three questionnaires [QuickDASH, PRWHE, PEM]. For analysis, we compared our results to the preoperative measures, contralateral hand, and to a previous study on a similar cohort looking at thumb strength following trapeziectomy. Results. 42 arthrodesis were performed, and 24 were available for follow-up. The average follow-up time was 77 months and the average age was 51 years old. Overall, we found a statistically significant improvement in thumb strength following surgery. Mean preoperative grip strength was 21.4kg and 32.5kg postoperatively (= +11kg). Preoperative pinch strength was 5.5kg and 7kg postoperatively (= +1.5kg). These results were significantly higher compared to the trapeziectomy cohort. We also found an improvement in 1st CMCJ ROM post-operatively. 7 complications were reported (29.1%). 4 were metalware-related and 3 were non-union. QuickDASH score significantly improved from a median of 42.95 to 12.5 while PRWHE from 67.5 to 14.5. Overall patient satisfaction was 87.4%. Conclusion. 1st CMCJ arthrodesis leads to an improvement in thumb function, pain and range of movement and results in high patient satisfaction, and therefore should be recommended for younger patients who need a pain-free and strong thumb

Aims. There has been an increasing use of early operative fixation for scaphoid fractures, despite uncertain evidence. We conducted a meta-analysis to evaluate up-to-date evidence from randomized controlled trials (RCTs), comparing the effectiveness of the operative and nonoperative treatment of undisplaced and minimally displaced (≤ 2 mm displacement) scaphoid fractures. Methods. A systematic review of seven databases was performed from the dates of their inception until the end of March 2021 to identify eligible RCTs. Reference lists of the included studies were screened. No language restrictions were applied. The primary outcome was the patient-reported outcome measure of wrist function at 12 months after injury. A meta-analysis was performed for function, pain, range of motion, grip strength, and union. Complications were reported narratively. Results. Seven RCTs were included. There was no significant difference in function between the groups at 12 months (Hedges’ g 0.15 (95% confidence interval -0.02 to 0.32); p = 0.082). The complication rate was higher in the operative group and involved more serious complications. Conclusion. We found no difference in functional outcome at 12 months for fractures of the waist of the scaphoid with ≤ 2 mm displacement treated operatively or nonoperatively. The complication rate was higher with operative treatment. Cite this article: Bone Joint J 2022;104-B(8):953–962

Objectives. To evaluate the neck strength of school-aged rugby players, and to define the relationship with proxy physical measures with a view to predicting neck strength. Methods. Cross-sectional cohort study involving 382 rugby playing schoolchildren at three Scottish schools (all male, aged between 12 and 18 years). Outcome measures included maximal isometric neck extension, weight, height, grip strength, cervical range of movement and neck circumference. Results. Mean neck extension strength increased with age (p = 0.001), although a wide inter-age range variation was evident, with the result that some of the oldest children presented with the same neck strength as the mean of the youngest group. Grip strength explained the most variation in neck strength (R. 2. = 0.53), while cervical range of movement and neck girth demonstrated no relationship. Multivariable analysis demonstrated the independent effects of age, weight and grip strength, and the resultant model explained 62.1% of the variance in neck strength. This model predicted actual neck strength well for the majority of players, although there was a tendency towards overestimation at the lowest range and underestimation at the highest. Conclusion. A wide variation was evident in neck strength across the range of the schoolchild-playing population, with a surprisingly large number of senior players demonstrating the same mean strength as the 12-year-old mean value. This may suggest that current training regimes address limb strength but not neck strength, which may be significant for future neck injury prevention strategies. Age, weight and grip strength can predict around two thirds of the variation in neck strength, however specific assessment is required if precise data is sought

Aims. Isolated fractures of the ulnar diaphysis are uncommon, occurring at a rate of 0.02 to 0.04 per 1,000 cases. Despite their infrequency, these fractures commonly give rise to complications, such as nonunion, limited forearm pronation and supination, restricted elbow range of motion, radioulnar synostosis, and prolonged pain. Treatment options for this injury remain a topic of debate, with limited research available and no consensus on the optimal approach. Therefore, this trial aims to compare clinical, radiological, and functional outcomes of two treatment methods: open reduction and internal fixation (ORIF) versus nonoperative treatment in patients with isolated ulnar diaphyseal fractures. Methods. This will be a multicentre, open-label, parallel randomized clinical trial (under National Clinical Trial number NCT01123447), accompanied by a parallel prospective cohort group for patients who meet the inclusion criteria, but decline randomization. Eligible patients will be randomized to one of the two treatment groups: 1) nonoperative treatment with closed reduction and below-elbow casting; or 2) surgical treatment with ORIF utilizing a limited contact dynamic compression plate and screw construct. The primary outcome measured will be the Disabilities of the Arm, Shoulder and Hand questionnaire score at 12 months post-injury. Additionally, functional outcomes will be assessed using the 36-Item Short Form Health Survey and pain visual analogue scale, allowing for a comparison of outcomes between groups. Secondary outcome measures will encompass clinical outcomes such as range of motion and grip strength, radiological parameters including time to union, as well as economic outcomes assessed from enrolment to 12 months post-injury. Ethics and dissemination. This trial has been approved by the lead site Conjoint Health Research Ethics Board (CHREB; REB14-2004) and local ethics boards at each participating site. Findings from the trial will be disseminated through presentations at regional, national, and international scientific conferences and public forums. The primary results and secondary findings will be submitted for peer-reviewed publication. Cite this article: Bone Jt Open 2024;5(5):411–418

We report a new surgical technique of open carpal tunnel release with subneural reconstruction of the transverse carpal ligament and compare this with isolated open and endoscopic carpal tunnel release. Between December 2007 and October 2011, 213 patients with carpal tunnel syndrome (70 male, 143 female; mean age 45.6 years; 29 to 67) were recruited from three different centres and were randomly allocated to three groups: group A, open carpal tunnel release with subneural reconstruction of the transverse carpal ligament (n = 68); group B, isolated open carpal tunnel release (n = 92); and group C, endoscopic carpal tunnel release (n = 53). At a mean final follow-up of 24 months (22 to 26), we found no significant difference between the groups in terms of severity of symptoms or lateral grip strength. Compared with groups B and C, group A had significantly better functional status, cylindrical grip strength and pinch grip strength. There were significant differences in Michigan Hand Outcome scores between groups A and B, A and C, and B and C. Group A had the best functional status, cylindrical grip strength, pinch grip strength and Michigan Hand Outcome score. Subneural reconstruction of the transverse carpal ligament during carpal tunnel decompression maximises hand strength by stabilising the transverse carpal arch.

Thumb Carpometacarpal (CMC) arthritis is a common pathology of the hand. Surgical treatment with thumb reconstruction is well described. Retrospective outcomes have been described for multiple techniques, suggesting patient satisfaction with multiple different techniques. The Thompson technique uses a slip of Abductor Pollicis Longus for suspension and interposition as well as excision of the trapezium. Retrospective outcomes suggest good patient satisfaction. We describe the improvement in Patient rated outcomes scores (PROS) and changes in pinch and grip strength in a prospectively collected cohort of patients treated with a modification of the Thompson technique. To assess changes in Patient-Rated Wrist Evaluation (PRWE) and Disabilities of the Arm, Shoulder, and Hand (QDASH) scores, as well as to determine the percentage of patients that surpassed the Minimal Clinically Important Difference (MCID) figure that has been described in the literature for these tests. In addition, measurements for evaluation of pinch and grip strength prior to surgery, at six, and at twelve months follow-up were done. Between June 2016 and February 2019, a consecutive prospective series of Thirty-seven LRTI procedures with APL suspension arthroplasty (Thompson technique) were performed on 34 patients with osteoarthritis of the thumb CMC joint (24 women / 13 men; age 63±8.553). All surgeries were performed by the senior surgeon. Data was collected as part of a wrist pain database. Patients failing conservative treatment and electing surgical management of thumb arthritis were enrolled into the database. Patients were evaluated pre-operatively with the PRWE and QDASH questionnaires and grip and pinch strength measurements, and postoperatively at 6 and 12 months. The MCID for QDASH and PRWE is 14 and will be evaluated at the same time points for each patient. Paired student T-test was used to determine differences in the means. Data are presented as mean ± SD unless stated otherwise. Differences with p<.05 were considered significant. Compared to the pre-operative assessment, at six months, the means of PRWE pain score and PRWE functional score decreased significantly (32.824 SD±10.721 vs. 19.265 SD±12.268 and 30.262 SD±10.050 vs. 16.431 SD± 9.697 respectively, n=34,, p<0.05). 69% of the patients surpassed the MCID of 14 six months after the surgery. In addition, QDASH mean score also dropped from 56.108 to 32.219 (SD± 21.375 n=32. p<0.05) at six months. At one year, 76% of the patients were above the MCID of 14. The mean scores of these three questionnaires did not show significant change between six and twelve months. Compared to the initial pre-operative assessment, we found no statistically significant difference in the means of grip strength, point pinch, and lateral key pinch at six and twelve months. Thumb reconstruction with APL suspension arthroplasty demonstrates significant improvement in pain and functionality. No significant improvement in grip and pinch strength is observed, even at one year postoperatively

Aims. The aims of this study were to compare the mid-term outcomes of patients with late-stage arthritis of the wrist treated with proximal row carpectomy (PRC) and dorsal capsular interposition (DCI) arthroplasty with a matched cohort treated with routine PRC alone. Patients and Methods. A total of 25 arthritic wrists (24 patients) with pre-existing degenerative changes of the proximal capitate and/or the lunate fossa of the radius were treated with PRC + DCI over a ten-year period. This group of patients were matched 1:2 with a group of 50 wrists (48 patients) without degenerative changes in the capitate or lunate fossa that were treated with a routine PRC alone during the same period. The mean age of the patients at the time of surgery was 56.8 years (25 to 81), and the demographics and baseline range of movement of the wrist, grip strength, Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, and Patient-Rated Wrist Evaluation (PRWE) score were similar in both groups. . Results. At a mean follow-up of 5.9 years (1.8 to 11.8), significant improvements in mean grip strength, the flexion-extension arc of movement of the wrist, QuickDASH, and PRWE scores were seen in both groups. There was no diifference between the groups for any of the outcomes. One patient in the PRC + DCI group required additional surgery for a deep infection, while two in the PRC group had complications (one wound dehiscence requiring revision closure, one transient radial sensory neuritis). One patient in each group required total arthrodesis of the wrist for progressive degenerative radiocarpal changes. A total of 70 patients (93%) were satisfied with the outcomes. Conclusion. PRC with DCI is an effective form of treatment for late-stage arthritis of the wrist involving the capitolunate joint, with mid-term outcomes that are similar to those in patients without degenerative changes affecting the capitate or lunate fossa who are treated with a routine PRC alone.

Aims. The aim of this study was to assess arthritis of the basal joint of the thumb quantitatively using bone single-photon emission CT/CT (SPECT/CT) and evaluate its relationship with patients’ pain and function. Methods. We retrospectively reviewed 30 patients (53 hands) with symptomatic basal joint arthritis of the thumb between April 2019 and March 2020. Visual analogue scale (VAS) scores for pain, grip strength, and pinch power of both hands and Patient-Rated Wrist/Hand Evaluation (PRWHE) scores were recorded for all patients. Basal joint arthritis was classified according to the modified Eaton-Glickel stage using routine radiographs and the CT scans of SPECT/CT, respectively. The maximum standardized uptake value (SUVmax) from SPECT/CT was measured in the four peritrapezial joints and the highest uptake was used for analysis. Results. According to Eaton-Glickel classification, 11, 17, 17, and eight hands were stage 0 to I, II, III, and IV, respectively. The interobserver reliability for determining the stage of arthritis was moderate for radiographs (k = 0.41) and substantial for CT scans (k = 0.67). In a binary categorical analysis using SUVmax, pain (p < 0.001) and PRWHE scores (p = 0.004) were significantly higher in hands with higher SUVmax. Using multivariate linear regression to estimate the pain VAS, only SUVmax (B 0.172 (95% confidence interval (CI) 0.065 to 0.279; p = 0.002) showed a significant association. Estimating the variation of PRWHE scores using the same model, only SUVmax (B 1.378 (95% CI, 0.082 to 2.674); p = 0.038) showed a significant association. Conclusion. The CT scans of SPECT/CT provided better interobserver reliability than routine radiographs for evaluating the severity of arthritis. A higher SUVmax in SPECT/CT was associated with more pain and functional disabilities of basal joint arthritis of the thumb. This approach could be used to complement radiographs for the evaluation of patients with this condition. Cite this article: Bone Joint J 2021;103-B(8):1380–1385

Aims. Following cast removal for nonoperatively treated distal radius fractures, rehabilitation facilitated by advice leaflet and advice video were compared to a course of face-to-face therapy. Methods. Adults with an isolated, nonoperatively treated distal radius fracture were included at six weeks post-cast removal. Participants were randomized to delivery of rehabilitation interventions in one of three ways: an advice leaflet; an advice video; or face-to-face therapy session(s). The primary outcome measure was the Disabilities of the Arm, Shoulder and Hand (DASH) score at six weeks post intervention and secondary outcome measures included DASH at one year, DASH work subscale, grip strength, and range of motion at six weeks and one year. Results. A total of 116 (97%) of 120 enrolled participants commenced treatment. Of those, 21 were lost to follow-up, resulting in 30 participants in the advice leaflet, 32 in the advice video, and 33 face-to-face therapy arms, respectively at six weeks of follow-up. There was no significant difference between the treatment groups in the DASH at six weeks (advice leaflet vs face-to-face therapy, p = 0.69; advice video vs face-to-face therapy, p = 0.56; advice leaflet vs advice video, p = 0.37; advice leaflet vs advice video vs face-to-face therapy, p = 0.63). At six weeks, there were no differences in any secondary outcome measures except for the DASH work subscale, where face-to-face therapy conferred benefit over advice leaflet (p = 0.01). Conclusion. Following cast removal for nonoperatively treated distal radius fractures, offering an advice leaflet or advice video for rehabilitation gives equivalent patient-reported outcomes to a course of face-to-face therapy.

Aims. The aims of this study were to evaluate the clinical and radiological outcomes of the Universal-2 total wrist arthroplasty (TWA) in patients with rheumatoid arthritis. Patients and Methods. This was a retrospective review of all 95 Universal-2 TWAs which were performed in our institution between 2003 to 2012 in patients with rheumatoid arthritis. A total of six patients were lost to follow-up and two died of unrelated causes. A total of ten patients had bilateral procedures. Accordingly, 75 patients (85 TWAs) were included in the study. There were 59 women and 16 men with a mean age of 59 years (26 to 86). The mean follow-up was 53 months (24 to 120). Clinical assessment involved recording pain on a visual analogue score, range of movement, grip strength, the Quick Disabilities of the Arm, Shoulder and Hand (DASH) and Wrightington wrist scores. Any adverse effects were documented with particular emphasis on residual pain, limitation of movement, infection, dislocation and the need for revision surgery. Radiographic assessment was performed pre-operatively and at three, six and 12 months post-operatively, and annually thereafter. Arthroplasties were assessed for distal row intercarpal fusion and loosening. Radiolucent zones around the components were documented according to a system developed at our institution. Results. The mean worst pain was 8.1 (3 to 10) pre-operatively and 5.4 (0 to 10) at latest follow-up (p <  0.001). Movements were preserved with mean dorsiflexion of 29. o . (0. o. to 70. o. ) and palmar flexion of 21. o. (0. o. to 50. o. ). The mean grip strength was 4.8 kg (1.7 to 11.5) pre-operatively and 10 kg (0 to 28) at final follow-up (p < 0.001). The mean QuickDASH and Wrightington wrist scores improved from 61 (16 to 91) to 46 (0 to 89) and 7.9 (1.8 to 10) to 5.7 (0 to 7.8) (p <  0.001). A total of six patients (7%) had major complications; three required revision arthroplasty and three an arthrodesis. The Kaplan-Meier probability of survival using removal of the components as the endpoint was 91% at 7.8 years (95% confidence interval 84 to 91). Conclusion. The Universal-2 TWA is recommended for use in patients with rheumatoid arthritis. Cite this article: Bone Joint J 2016;98-B:1642–7

Aims. To compare operative and nonoperative treatment for displaced distal radius fractures in patients aged over 65 years. Methods. A total of 100 patients were randomized in this non-inferiority trial, comparing cast immobilization with operation with a volar locking plate. Patients with displaced AO/OTA A and C fractures were eligible if one of the following were found after initial closed reduction: 1) dorsal angulation > 10°; 2) ulnar variance > 3 mm; or 3) intra-articular step-off > 2 mm. Primary outcome measure was the abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) after 12 months. Secondary outcome measures were the Patient-Rated Wrist and Hand Evaluation (PRWHE), EuroQol-5 dimensions 5-level questionnaire (EQ-5D-5L), range of motion (ROM), grip strength, “satisfaction with wrist function” (score 0 to 10), and complications. Results. In all, 89 women and 11 men were included. Mean age was 74 years (65 to 91). Nonoperative treatment was non-inferior to operation with a five-point difference in median QuickDASH after 12 months (p = 0.206). After three and six months QuickDASH favoured the operative group (p = 0.010 and 0.030). Median values for PRWHE were 19 (interquartile range (IRQ) 10 to 32) in the operative group versus ten (IQR 1 to 31) in the nonoperative group at three months (p = 0.064), nine (IQR 2 to 20) versus five (IQR 0 to 13) (p = 0.020) at six months, and two (IQR 0 to 12) versus zero (IQR 0 to 8) (p = 0.019) after 12 months. Range of motion was similar between the groups. The EQ-5D-5L index score was better (mean difference 0.07) in the operative group at three and 12 months (p = 0.008 and 0.020). The complication rate was similar (p = 0.220). The operated patients were more satisfied with wrist function (median 8 (IQR 6 to 9) vs 6 (IQR 5 to 7) at three months, p = 0.002; 9 (IQR 7 to 9) vs 8 (IQR 6 to 8) at six months, p = 0.002; and 10 (IQR 8 to 10) vs 8 (IQR 7 to 9) at 12 months, p < 0.001). Conclusion. Nonoperative treatment was non-inferior to operative treatment based on QuickDASH after one year. Patients in the operative group had a faster recovery and were more satisfied with wrist function. Results from previous trials comparing operative and nonoperative treatment for displaced distal radius fractures in the elderly vary between favouring the operative group and showing similar results between the treatments. This randomized trial suggests that most elderly patients may be treated nonoperatively. Cite this article: Bone Joint J 2021;103-B(2):247–255

Aims. Patients with midcarpal instability are difficult to manage. It is a rare condition, and few studies have reported the outcomes of surgical treatment. No prospective or retrospective study has reported the results of arthroscopic palmar capsuloligamentous suturing. Our aim was to report the results of a prospective study of arthroscopic suture of this ligament complex in patients with midcarpal instability. Methods. This prospective single-centre study was undertaken between March 2012 and May 2022. The primary outcome was to evaluate the functional outcomes of arthroscopic palmar midcarpal suture. The study included 12 patients, eight male and four female, with a mean age of 27.5 years (19 to 42). They were reviewed at three months, six months, and one year postoperatively. Results. There was a significant improvement in flexion, extension, grip strength, abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire score, and pain, in all patients. After telephone contact with all patients in March 2023, at a mean follow-up of 3.85 years (2.2 to 6.25), no patient had a persistent or recurrent clunk. Conclusion. Arthroscopic suture of the midcarpal capsuloligamentous complex represents a minimally invasive, easy, and reproducible technique for the management of patients with midcarpal instbility, with a clear improvement in function outcomes and no complications.

We report the use of a free vascularised iliac bone graft in the treatment of 21 patients (19 men and 2 women) with an avascular nonunion of the scaphoid in which conventional bone grafting had previously failed. The mean age of the patients was 32 years (23 to 46) and the dominant wrist was affected in 14. The mean interval from fracture to the vascularised bone grafting was 39 months (9 to 62). Pre-operative MRI showed no contrast enhancement in the proximal fragment in any patient. Fracture union was assessed radiologically or with CT scans if the radiological appearances were inconclusive. At a mean follow-up of 5.6 years (2 to 11) union was obtained in 16 patients. The remaining five patients with a persistent nonunion continued to experience pain, reduced grip strength and limited range of wrist movement. In the successfully treated patients the grip strength and range of movement did not recover to match the uninjured side. Prevention of progressive carpal collapse, the absence of donor site morbidity, good subjective results and pain relief, justifies this procedure in the treatment of recalcitrant nonunion of the scaphoid

Four-Corner Fusions (4CF) and Proximal Row Carpectomies (PRC) are common procedures utilized to treat carpal pathologies and radial sided wrist pain. Usually, the range of motion (ROM) and grip strength (GS) is affected by such conditions. Literature quotes significant reduction in ROM (50–60%) and grip strength (GS) (80% of normal) with PRC and 4CF. This study aims to determine the correlation between pre-operative ROM and GS and post-operative ROM and GS for patients with wrist pain undergoing PRC or 4CF. We hypothesize that ROM between pre-operative and post-operative patients does not change, but GS improves. Data from a prospective database of patients with wrist pain was searched to identify patients who have undergone PRC or 4CF with one year follow-up completed in the past two years. 17 such participants were identified. The diagnosis, pre-operative ROM in flexion, extension, radial deviation, ulnar deviation, pronation and supination, as well as GS at time of surgery and at six months and one year follow up were identified and assessed. The data was analysed to determine correlation between pre-and postoperative ROM and GS. The analysis was subdivided to compare patients treated with PRC versus patients with 4CF. No significant difference between pre- and post-operative ROM was detected, except in flexion at 6 months post-operatively. The average flexion was significantly lower at 6 months (p=0.0251) compared to pre-operative levels. Average flexion pre-operatively and at 6 and 12 months was found to be 46.6 (SD=15), 34.3 (SD=13.3), 51.2 (SD=21.5) respectively. Extension was at 41.4 (SD=15.3) pre-operatively and at 33.4 (SD=12.8) and 42.1 (SD=15.5) at 6 and 12 months post-operatively. Similarly, radial and ulnar deviation averages pre-operatively and at 6 and 12 months post-operatively were found to be 11.33 (SD=5.9), 11.9 (SD=4.5), 16 (SD=8.2) [radial deviation] and 24.1 (SD=8.3), 21.4 (SD=7.3), 26 (SD=12.8) [ulnar deviation]. No significant difference was found in GS at 6 months post-operative. However, significant difference at 12 months post-operatively was observed with an average GS of 28.4 kg (SD=12.8) [p=0.0385]. Average GS pre-operatively and at 6 months was 15.8 kg (SD=9.7) and 17.3 kg (SD=8.9) respectively. This study provides an insight on ROM and GS after PRC and 4CF. It shows that patients do not gain or lose ROM after surgery. As expected, GS improves with treatment as the pain diminishes. It is interesting to note that flexion gets worse at 6 months post-operatively before it bounces back to pre-operative levels

The progressive painful and disabling predicament of patients with severe osteoarthritis awaiting a total hip or knee arthroplasty (THA/TKA) results in a decline in muscle mass, strength and function also known as Sarcopenia. We conducted a cross-sectional, prospective study of patients on the waiting-list for a THA/TKA in the South Australian public healthcare system and compared the findings to healthy participants and patients newly referred from their general practitioners. Participants with a history of joint replacements, pacemakers and cancers were excluded from this study. Outcomes of this study included (i) sarcopenia screening (SARC-F ≥4); (ii) sarcopenia, defined as low muscle strength (hand grip strength M<27kg; F<16kg), low muscle quality (skeletal muscle index M<27%, F<22.1%) and low physical performance (short physical performance battery ≤8). Additional outcomes include descriptions of the recruitment feasibility, randomisation and suitability of the assessment tools. 29 healthy controls were recruited; following screening, 83% (24/29) met the inclusion criteria and 75% (18/24) were assessed. 42 newly referred patients were recruited; following screening, 67% (30/45) met the inclusion criteria and 63% (19/30) were assessed. 68 waiting list patients were recruited; following recruitment, 24% (16/68) met the inclusion criteria and 75% (12/16) were assessed. Preliminary data shows increasing waiting time is associated with higher SARC-F scores, lower hand grip strength and lower muscle quality. As a pilot study, preliminary data demonstrate that: (1) study subjects’ willingness to participate will enable a larger study to be conducted to establish the prevalence of sarcopenia and the diagnostic cut-off points for this patient group. (2) SARC-F is a suitable tool to screen for sarcopenia. (3) There is a positive correlation between waiting time for a THA/TKA and sarcopenia

This study aims to compare the outcomes of Volar locking plating (VLP) versus percutaneous Kirschner wires (K-wire) fixation for surgical management of distal radius fractures. We systematically searched multiple databases, including MEDLINE for randomized controlled trials (RCTs) comparing outcomes of VLP fixation and K-wire for treatment of distal radius fracture in adults. The methodological quality of each study was assessed by the Cochrane Risk of Bias tool. Patient-reported outcomes, functional outcomes, and complications at 1 year follow up were evaluated. Meta-analysis was performed using random-effects models and results presented as risk ratios (RRs) or mean differences (MDs) with 95% confidence interval (CI). 13 RCTs with 1336 participants met the inclusion criteria. Disabilities of the Arm, Shoulder and Hand (DASH) scores were significantly better for VLP fixation (MD= 2.15; 95% CI, 0.56-3.74; P = 0.01; I2=23%). No significant difference between the two procedures for grip strength measured in kilograms (MD= −3.84; 95% CI,-8.42-0.74; P = 0.10; I2=52%) and Patient-Rated Wrist Evaluation (PRWE) scores (MD= −0.06; 95% CI,-0.87-0.75; P = 0.89; I2=0%). K-wire treatment yielded significantly improved extension (MD= −4.30; P=0.04) but with no differences in flexion, pronation, supination, and radial deviation (P >0.05). The risk of complications and rate of reoperation were similar for the two procedures (P >0.05). This meta-analysis suggests that VLP fixation improves DASH score at 12 months follow up, however, the difference is small and unlikely to be clinically important. Existing literature does not provide sufficient evidence to demonstrate the superiority of either VLP or K-wire treatment in terms of patient-reported outcomes, functional outcomes, and complications

Aim: The primary purpose of this study was to establish data concerning normal hand grip strength in the population of N.W Greece. Material and Methods: The Jamar dynamometer was used to measure grip strength. A sample of 115 males and 117 females, with no extremity disability or injury, aged 21 to 58 years, from the Ioannina area was tested. The dynamometer was tested in a standing position, with shoulder adducted and neutrally rotated, elbow flexed at 90 degrees and forearm and wrist in neutral position. Each participant was asked to grip first with the right and then with the left hand three consecutive times. The highest grip strength for each hand was used for analysis. All complementary factors such as age, sex, height, weight, hand dominance for writing and exercise and living habits were recorded. Results: Grip strength diminishes curvilinearly with age, and men are consistently stronger than women. Mean maximum grip for women was 67 pounds and for men was 123 pounds. The hand dominance does not significantly affect hand strength scores. The mean grip strength of the left hand was about 90% that of the right hand. In left-handed participants, mean grip was the same for both hands. The results from this study showed that sex is the most important determinant of hand grip strength. Conclusions: The random sample, the high participation rate of this study and the number of the factors that affect the hand strength give the highest validity in this study. These data suggest a basis to help hand surgeons as a guide regarding grip strength in the treatment of upper extremity pathologic conditions and postoperative evaluation

This systematic review and meta-analysis aimed to compare the outcome of operative and non-operative management in adults with distal radius fractures, with an additional elderly subgroup analysis. The main outcome was 12-month PRWE score. Secondary outcomes included DASH score, grip strength, complications and radiographic parameters. Randomised controlled trials of patients aged ≥18yrs with a dorsally displaced distal radius fractures were included. Studies compared operative intervention with non-operative management. Operative management included open reduction and internal fixation, Kirschner-wiring or external fixation. Non-operative management was cast/splint immobilisation with/without closed reduction. Version 2 of the Cochrane risk-of-bias tool was used. After screening 1258 studies, 16 trials with 1947 patients (mean age 66yrs, 76% female) were included in the meta-analysis. Eight studies reported PRWE score and there was no clinically significant difference at 12 weeks (MD 0.16, 95% confidence interval [CI] −0.75 to 1.07, p=0.73) or 12 months (mean difference [MD] 3.30, 95% CI −5.66 to −0.94, p=0.006). Four studies reported on scores in the elderly and there was no clinically significant difference at 12 weeks (MD 0.59, 95% CI −0.35 to 1.53, p=0.22) or 12 months (MD 2.60, 95% CI −5.51 to 0.30, p=0.08). There was a no clinically significant difference in DASH score at 12 weeks (MD 10.18, 95% CI −14.98 to −5.38, p<0.0001) or 12 months (MD 3.49, 95% CI −5.69 to −1.29, p=0.002). Two studies featured only elderly patients, with no clinically important difference at 12 weeks (MD 7.07, 95% CI −11.77 to −2.37, p=0.003) or 12 months (MD 3.32, 95% CI −7.03 to 0.38, p=0.08). There was no clinically significant difference in patient-reported outcome according to PRWE or DASH at either timepoint in the adult group as a whole or in the elderly subgroup

Metacarpal fractures represent up to 33% of all hand fractures; of which the majority can be treated non-operatively. Previous research has shown excellent putcomes with non-operative treatment yet surgical stabilisation is recommended to avoid malrotation and symptomatic shortening. It is unknown whether operative is superior to non-operative treatment in oblique or spiral metacarpal shaft fractures. The aim of the study was to compare non-operative treatment of mobilisation with open surgical stabilisation. 42 adults (≥ 18 years) with a single displaced oblique or spiral metacarpal shaft fractures were randomly assigned in a 1:1 pattern to either non-operative treatment with free mobilisation or operative treatment with open reduction and fixation with lag screws in a prospective study. The primary outcome measure was grip-strength in the injured hand in comparison to the uninjured hand at 1-year follow-up. The Disabilities of the Arm, Shoulder and Hand Score, ranges of motion, metacarpal shortening, complications, time off work, patient satisfaction and costs were secondary outcomes. All 42 patients attended final follow-up after 1 year. The mean grip strength in the non-operative group was 104% (range 73–250%) of the contralateral hand and 96% (range 58–121%) in the operatively treated patients. Mean metacarpal shortening was 5.0 (range 0–9) mm in the non-operative group and 0.6 (range 0–7) mm in the operative group. There were five minor complications and three revision operations, all in the operative group. The costs for non-operative treatment were estimated at 1,347 USD compared to 3,834USD for operative treatment; sick leave was significantly longer in the operative group (35 days, range 0–147) than in the non-operative group (12 days, range 0–62) (p=0.008). When treated with immediate free mobilization single, patients with displaced spiral or oblique metacarpal shaft fractures have outcomes that are comparable to those after operative treatment, despite some metacarpal shortening. Complication rates, costs and sick leave are higher with operative treatment. Early mobilisation of spiral or long oblique single metacarpal fractures is the preferred treatment.

Aims. The aim of this study was to investigate the difference in functional outcome after repair and non-repair of the pronator quadratus muscle in patients undergoing surgical treatment for a distal radial fracture with volar plating. Patients and Methods. A total of 72 patients with a distal radial fracture were included in this randomized clinical trial. They were allocated to have the pronator quadratus muscle repaired or not, after volar locked plating of a distal radial fracture. The patients, the assessor, the primary investigator, and the statistician were blinded to the allocation. Randomization was irreversibly performed using a web application that guaranteed a secure and tamper-free assignment. The primary outcome measure was the Patient Rated Wrist Evaluation (PRWE) after 12 months. Secondary outcomes included the Disabilities of the Arm, Shoulder and Hand (DASH) score, pronation strength, grip strength, the range of pronation and supination, complications, and the operating time. Results. Of the 72 patients, 63 (87.5%) completed follow-up for the primary outcome measure: 31 (86.1%) from the non-repair group and 32 (88.9%) from the repair group. At the 12-month follow-up, the mean difference in PRWE of 5.47 (95% confidence interval (CI) -4.02 to 14.96) between the repair (mean 18.38 (95% CI 10.34 to 26.41)) and non-repair group (mean 12.90 (95% CI 7.55 to 18.25)) was not statistically significant (p = 0.253). There was a statistically significant difference between pronation strength, favouring non-repair. We found no difference in the other secondary outcomes. Conclusion. We found that repairing pronator quadratus made no difference to the clinical outcome, 12 months after volar plating of a distal radial fracture. We conclude that there is no functional advantage in repairing this muscle under these circumstances and advise against it. Cite this article: Bone Joint J 2019;101-B:1498–1505

Objectives. To investigate the differences of open reduction and internal fixation (ORIF) of complex AO Type C distal radius fractures between two different models of a single implant type. Methods. A total of 136 patients who received either a 2.4 mm (n = 61) or 3.5 mm (n = 75) distal radius locking compression plate (LCP DR) using a volar approach were followed over two years. The main outcome measurements included motion, grip strength, pain, and the scores of Gartland and Werley, the Short-Form 36 (SF-36) and the Disabilities of the Arm, Shoulder, and Hand (DASH). Differences between the treatment groups were evaluated using regression analysis and the likelihood ratio test with significance based on the Bonferroni corrected p-value of < 0.003. Results. The groups were similar with respect to baseline and injury characteristics as well as general surgical details. The risk of experiencing a complication after ORIF with a LCP DR 2.4 mm was 18% (n = 11) compared with 11% (n = 8) after receiving a LCP DR 3.5 mm (p = 0.45). Wrist function was also similar between the cohorts based on the mean ranges of movement (all p > 0.052) and grip strength measurements relative to the contralateral healthy side (p = 0.583). In addition, DASH and SF-36 component scores as well as pain were not significantly different between the treatment groups throughout the two-year period (all p ≥ 0.005). No patient from either treatment group had a step-off > 2 mm. Conclusions. Differences in plate design do not influence the overall final outcome of fracture fixation using LCP.

This is a retrospective study of six children with ununited scaphoid fractures treated conservatively. Their mean age was 12.8 years (9.7 to 16.3). Five had no early treatment. Radiological signs of nonunion were found at a mean of 4.6 months (3 to 7) after injury. Treatment consisted of cast immobilisation until clinical and radiological union. The mean clinical and radiological follow-up was for 67 months (17 to 90). We assessed the symptoms, the range of movement of the wrist and the grip strength to calculate the Modified Mayo Wrist score. The fracture united in all patients after a mean period of immobilisation of 5.3 months (3 to 7). Five patients were pain free; one had mild pain. All returned to regular activities, and had a range of movement and grip strength within 25% of normal, resulting in an excellent Modified Mayo Wrist score. Prolonged treatment with cast immobilisation resulted in union of the fracture and an excellent Modified Wrist Score in all patients

Summary. Arthroscopic decompression of the lunate decreases clinical symptoms and slows progression of Kienböck's Disease. Introduction. The purpose of this study was to investigate the outcomes of patients suffering from avascular necrosis of the lunate, or Kienböck's Disease, who received arthroscopic decompression to treat the ischemic lunate. Previous studies have demonstrated an elevated intraosseus pressure in the ischemic lunate, and it has been hypothesised that ischemia in the lunate is secondary to this elevated pressure and subsequent venous congestion, as opposed to diminished arterial supply. Based on this work we have used decompression of the lunate to prevent progression of the disease. Patients and Methods. 21 patients, (22 wrists), reported to a single surgeon with a chief complaint of unremitting wrist pain and the subsequent diagnosis was Kienböck's disease, stages I, II, IIIA or IIIB. Range of motion measurement and grip strength, as well as self-reported outcome measures such as Disabilities of the Arm, Shoulder and Hand (DASH) and Modified Mayo, were obtained preoperatively and post operatively at 2, 7 and 12 months. The patients were treated operatively with arthroscopic decompression of the lunate. The lunate was approached dorsally at the interosseous lunotriquetral and the scapholunate ligament areas with an arthroscopic shaver until brisk bleeding was achieved upon deflating the tourniquet. In some cases, the core of the lunate had to be penetrated with a 45 k-wire until bleeding was obtained. Of the 22 wrists treated arthroscopically with lunate decompression, 18 had both pre-surgical and post-surgical follow-up evaluations. Results. The patients who underwent lunate arthroscopic decompression surgery demonstrated a statistically significant improvement in DASH score at 7 and 12 months postoperatively (p<0.05). The preoperative DASH score average for this cohort was 51, while post-operative DASH scores averaged 23 and 17 at 7 and 12 months, respectively. The patients also demonstrated some overall improvement in pain, functionality, range of motion, and grip strength as demonstrated by the Modified Mayo wrist score. Notably, the patients demonstrated statistically significant improvement in grip strength post-operatively at 7-months (p<0.05) and 12-months (p<0.01). In addition, there was noted to be improvement in supination and ulnar deviation measurements post-operatively at 7 months and 12 months, respectively. Conclusion. This study demonstrates the clinical outcome of arthroscopic decompression of the lunate in patients suffering from Kienböck's Disease using the patient's subjective evaluations as well as range of motion and grip strength measurements. Arthroscopic decompression of the lunate decreases clinical symptoms and slows progression of Kienböck's Disease using a less invasive surgical intervention

Background. It was hypothesised that preserving a layer of gliding tissue, the parietal layer of the ulnar bursa, between the contents of the carpal tunnel and the soft tissues incised during carpal tunnel surgery might reduce scar pain and improve grip strength and function following open carpal tunnel decompression. Methods. Patients consented to randomisation to treatment with either preservation of the parietal layer of the ulnar bursa beneath the flexor retinaculum at the time of open carpal tunnel decompression (57 patients) or division of this gliding layer as part of a standard open carpal tunnel decompression (61 patients). Grip strength was measured, scar pain was rated and the validated Patient Evaluation Measure questionnaire was used to assess symptoms and disability pre-operatively and at eight to nine weeks following surgery in seventy-seven women and thirty-four men; the remaining seven patients were lost to follow-up. Results. There was no difference between the groups with respect to age, sex, hand dominance or side of surgery. Grip strength, scar pain and Patient Evaluation Measure score were not significantly different between the two groups, although there was a trend towards poorer subjective outcome as demonstrated by the questionnaire in the group in which the ulnar bursa within the carpal tunnel had been preserved. Preserving the ulnar bursa within the carpal tunnel did however result in a lower prevalence of suspected wound infection or inflammation (p=0.04). Conclusions. In this group of patients, preservation of the ulnar bursa around the median nerve during open carpal tunnel release produced no significant difference in grip strength or self-rated symptoms. We recommend incision of the ulnar bursa during open carpal tunnel decompression to allow complete visualisation of the median nerve and carpal tunnel contents

Pathologies such as Scapho-Lunate Advanced Collapse (SLAC), Scaphoid Non-union Advanced Collapse (SNAC) and Kienbock's disease can lead to arthritis in the wrist. Depending on the articular surfaces that are involved, motion preserving surgical procedures can be performed. Proximal Row Carpectomy (PRC) and Four Corner Fusion (4CF) are tried and tested surgical options. However, prospective studies comparing the two methods looking at sufficient sample sizes are limited in the literature. The purpose of this study was to prospectively compare the early results of PRC vs 4CF performed in a single centre. Patients with wrist arthritis were prospectively enrolled (2015 to 2021) in a single centre in Vancouver, Canada. Thirty-six patients and a total of 39 wrists underwent either a PRC (n=18) or 4CF (n=21) according to pre-operative clinical, radiographical, and intra-operative assessment. Patient-Rated Wrist Evaluation (PRWE) scores were obtained preoperatively, as well as at six months and one year post operatively. Secondary outcomes were range of motion (ROM) of the wrist, grip strength, reoperation and complication rates. Statistical significance was set at p=0.05. Respectively for PRC and 4CF, the average PRWE scores at baseline were 61.64 (SD=19.62) and 63.67 (SD=20.85). There was significant improvement at the six-month mark to 38.81 (SD=22.95) (p=0.031) and 41.33 (SD=26.61) (p=0.007), then further improvement at the 12month mark to 33.11 (SD=23.42) (p=0.007) and 36.29 (SD=27.25) (p=0.002). There was no statistical difference between the two groups at any time point. Regarding ROM, statistical difference was seen in pronation for the PRC group at the 6month mark from an average of 72.18 deg to 61.56 deg and in flexion at the 12 month mark from 47.89 deg to 33.50 deg. All other parameters did not show statistically significant difference post operatively. For ROM of the 4CF group, only flexion at the 12month mark showed statistically significant change from an average of 48.81 deg to 38.03 deg. There was no statistical difference in pre-operative ROM between the two groups. One patient in the 4CF group required a revision for delayed union, and three patients ended up with ulnar sided wrist pain. Patients undergoing PRC and 4CF showed significant improvement in post operative PRWE scores, this reflects existing literature. For 4CF care must be taken to minimise ulnar sided wrist pain by relatively shortening the unar sided carpal column mass. ROM analysis showed that patients lost some wrist flexion ROM post-operatively at the 12month mark with both PRC and 4CF. However, other ROM parameters were unchanged

Aims. Plate and screw fixation has been the standard treatment for painful conditions of the wrist in non-rheumatoid patients in recent decades. We investigated the complications, re-operations, and final outcome in a consecutive series of patients who underwent wrist arthrodesis for non-inflammatory arthritis. Patients and Methods. A total of 76 patients, including 53 men and 23 women, with a mean age of 50 years (21 to 79) underwent wrist arthrodesis. Complications and re-operations were recorded. At a mean follow-up of 11 years (2 to 18), 63 patients completed questionnaires, and 57 attended for clinical and radiological assessment. Results. Of the 76 patients, 46 (60.5%) had complications, resulting in 65 re-operations, mainly related to the plate and screws. In the 63 patients who completed the questionnaires, the mean Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) score was 36 (0 to 91), the mean Patient-Rated Wrist and Hand Evaluation (PRWHE) score was 40 (0 to 96), and 14 patients (22%) reported no wrist pain. Grip strength, pinch strength, and pronation and supination were significantly reduced compared with the contralateral forearm. The outcome was worse in patients who had previously undergone surgery to the wrist, and those with complications. A total of 13 are awaiting further re-operations, giving a total re-operation rate of 63% (40/63). Conclusion. We observed complications and re-operations throughout the follow-up period and therefore consider wrist arthrodesis to be more complicated than previously assumed. Many of the patients never got used to or accepted their stiff wrists and reported a substantial reduction in function and residual pain. Motion-sparing surgery should be offered prior to wrist arthrodesis. Cite this article: Bone Joint J 2019;101-B:852–859

The aim was to assess the long-term impact of humeral and forearm rodding on functional ability, grip strength, joint range of motion and angular deformity in children with osteogenesis imperfecta. A retrospective chart review was conducted on 57 children with osteogenesis imperfecta who underwent humeral rodding or forearm rodding at our institution between 1996 and 2013. Functional ability was assessed using the self-care and mobility domains of the Pediatric Evaluation and Disability Inventory (PEDI). Grip strength was measured using a dynamometer and joint range of motion with a goniometer. Deformity was measured on radiographs of the humerus or forearm. Outcomes were assessed pre-operatively and every year post-operatively. Differences between pre-operative and 1-year post-operative outcomes were compared using paired T-tests. In 44 patients with a minimum of 2 years follow-up, outcome measures at 1-year post-surgery were compared to those at the latest clinic visit (mean follow-up = 8.0 years). Humeral and forearm rodding resulted in a significant improvement in PEDI self-care score (mean change =5.75, p=0.028 for the humerus, mean change = 6.77, p=0.0017 for the forearm) and mobility score (mean change =3.59, p=0.008 for the humerus, mean change =7.21, p=0.020 for the forearm) at 1 year post-surgery. Grip strength improved following forearm rodding (mean change = +6.13N, p=0.015) but not humeral rodding. Joint range of movement improved following humeral rodding but not forearm rodding. There was a significant improvement in radiographic angular deformity of the forearm and humerus following surgery (p<0.0001). Over 80% of improvements were maintained in the long-term. Humeral and forearm rodding in children with osteogenesis imperfecta leads to long-term improvement in functional ability and angular deformity

Aims. The aim of this study was to compare the efficacy of a corticosteroid injection for the treatment of carpal tunnel syndrome (CTS) in patients with and without Raynaud’s phenomenon. Patients and Methods. In a prospective study, 139 patients with CTS were treated with a corticosteroid injection (10 mg triamcinolone acetonide); 34 had Raynaud’s phenomenon and 105 did not (control group). Grip strength, perception of touch with a Semmes-Weinstein monofilament and the Boston Carpal Tunnel Questionnaires (BCTQ) were assessed at baseline and at six, 12 and 24 weeks after the injection. The Cold Intolerance Severity Score (CISS) questionnaire was also assessed at baseline and 24 weeks after the injection

Patient disability and handicap following wrist injuries have been the focus of recent research interest. 1. However, the relative importance of each of the commonly-reported and easily-measured clinical outcome parameters such as the range of wrist movement and the grip strength on the level of actual wrist disability following distal radial fractures has not been investigated previously. The present study investigates the correlation between measurements of specific clinical parameters and the patient-rated wrist joint function following wrist fractures. A prospective assessment of unstable (AO types 23-A2, -A3, -C1 and -C2) fractures of the distal radius treated by closed reduction and percutaneous K-wire fixation followed by cast immobilisation was undertaken. One hundred consecutive observations were made during various follow-up time periods up to one year in a group of twenty-five patients (fifteen female and ten male patients, mean age 43 years – range 18 to 67 years). The clinical parameters tested were the range of wrist dorsiflexion, palmarflexion, pronation and supination (measured using a goniometer) and the mass grip strength (Jamar grip dynamometer) following removal of the plaster cast, expressed as percentage of the affected side relative to the opposite normal side. Additionally, each patient completed the Patient-Rated Wrist Evaluation (PRWE) Score. 1. A stepwise multiple regression multivariate model was employed to statistically analyse the relative effect (expressed as the regression coefficient, b) of each clinical parameter on the ‘Function Score’ part of the PRWE Score. Furthermore, the association between each clinical parameter and the Function Score part of the PRWE Score was also investigated using single-patient observations by calculating the correlation coefficient (r). The results of the statistical analysis (Minitab 12.1) gave the following regression (b) and correlation (r) coefficient values: grip strength (b=0.77, r=0.80), dorsiflexion (b=0.58,r=0.78),pronation (b=0.39,r=0.70),supination (b=0.38, r=0.63), palmarflexion (b=0.32, r=0.62). The present study shows that grip strength (expressed as percentage that of the unaffected side) is the most reliable index of wrist disability and the most sensitive indicator of return of wrist function, followed by the range of wrist dorsiflexion and pronation. Wrist supination and palmarflexion are the clinical outcome variables showing the weakest correlation with the wrist function as rated by the patients. These observations may facilitate correct interpretation and comparisons of the results of clinical studies on various methods of treatment of wrist trauma

The management of scapho-lunate (SL) instability remains controversial. Since 2001, the senior author has used a modified Brunelli tenodesis to achieve soft tissue stabilization in patients presenting with dynamic or static SL instability. From 2001 to 2009, 13 patients were prospectively studied. All patients complained of painful clicking in the wrist, inability to use the wrist for loading activities, and all had a positive scaphoid shift test (Kirk Watson). Wrist arthroscopy was performed to confirm the diagnosis and to confirm the absence of degenerative change in all cases. Data collection pre-operatively included, range of motion, grip strength, DASH score and pain score. All patients had wrist immobilisation in a forearm cast for six weeks post operatively. Physiotherapy commenced at that stage and clinical assessment was performed at 3 months, six months and 12 months post surgery. Patients were discharged from follow-up after 12 months. A significant improvement in grip strength and DASH score was documented at the 12 month post operative assessment. The range of wrist flexion was decreased in all patients. The majority returned to their original employment. All patients reported that their wrist instability symptoms were improved. Conclusion. Scapho-lunate ligament reconstruction using a split flexor carpi radialis tendon graft to achieve soft tissue stabilization, provided satisfactory results in patients with chronic SL instability. Improvement in DASH score and grip strength were documented at one year follow-up

The April 2015 Research Roundup360 looks at: MCID in grip strength and distal radial fracture; Experiencing rehab in a trial setting; Electrical stimulation and nerve recovery; Molecular diagnosis of TB?; Acetabular orientation: component and arthritis; Analgesia after knee arthroplasty; Bisphosphonate-associated femoral fractures

The purpose of this study was to evaluate the subjective and objective functional outcome after osteosynthesis of the forearm bone fractures with plates and screws (ORIF) or elastic nailing (CRIF). We evaluated 55 patients (45 men and 10 women) who underwent internal fixation of both forearm bones with CRIF or ORIF, concerning the range of motion of the forearm, wrist and elbow (pronation, supination, flexion and extension), grip strength and a validated outcome measure (DASH score). The mean duration of follow-up was 3 years, and standardized radiographs of the forearm were evaluated. The mean age was 41.6. We used the Student's t test to compare means and chi-square test to compare proportions. The mean (confidence interval 95%) of the DASH scale was 29.6 (22.6 to 36.5), significantly higher (p<0.001) than the normative value in the U.S. (10.1). There was a statistically significant reduction of forearm supination (86.4 vs. 64.6, p<0.001) and grip strength (0.63 vs. 0.48, p<0.001) in relation to the opposite member; grip strength decrease correlated with worse subjective outcome (p<0.02). There were no significant differences between groups undergoing ORIF or CRIF. The risk of nonunion and reintervention was not different between groups (p=0214). Forearm bones fractures are associated with high rates of consolidation and satisfactory mobility of the forearm since we obtain an anatomic reduction of the fracture, as is most easily achieved by plate fixation. However, elastic nailing is a less invasive technique that allows restoring function more quickly with less pain and no increased risk of complications. Given the scant scientific evidence currently available we will require a more comprehensive study to compare the anatomical and functional outcome after ORIF and CRIF

In a prospective randomized trial, we divided a group of patients with a clinically suspicious, although radiographically normal, acute fracture of the scaphoid into 2 groups, 1 treated with a cast (group I), the other with a splint (group II). There were 14 patients in group I, and 18 in group II. Patients were reviewed at 2,6, and 12 weeks for range of movement, grip strength, pain and satisfaction rating. Work disability costs were also calculated for both groups. Patients in group II had better range of movement and grip strength at 2 weeks, although complained of more pain. There was no difference in range of movement, grip strength, or pain at 6 or 12 weeks. Group II was more satisfied at 2 weeks, although not at 6 or 12 weeks. Group I required more time off work, and disability costs were significantly higher [€15,209 per person compared to €3,317 per person]. We recommend that all patients, with only a clinical suspicion of a fractured scaphoid, should have a short period of splint immobilization until symptoms resolve, or until further investigations reveal a fracture which can be appropriately treated. This policy is cost efficient and improves the short term outcome

A prospective study was made over a three-year period of 900 consecutive unilateral Colles' fractures. The radiographic features at the time of fracture, after reduction and one week later were measured and correlated with grip strength and range of movement at three years. The most significant radiographic feature to influence the outcome was the presence of shortening of the radius one week after reduction of the fracture. Persistent dorsal tilt, radiocarpal joint involvement and ulnar styloid fracture were each associated with reduced range of movement, but had no effect on grip strength. Extension of the fracture into the distal radio-ulnar joint was associated with reduced grip strength but had no effect on range of movement. Radial tilt of the radial fragment did not correlate with any aspect of the result after three years

Aim: To investigate factors that influence outcomes one year after distal radial fractures To investigate how deformity (radiologically), functional outcome and patient satisfaction affect one another. Background: Identifying the factors that influence outcome in DRF is important in anticipating and treating patients with potentially correctable factors that may affect recovery. Previous studies have looked at different sub-sets of the DRF group most often with patient reported outcomes. We have reviewed a large consecutive group of DRF looking at which factors influenced the outcomes. Methods: Data on 640 distal radial fractures was prospectively recorded over a 24 month period. The database was reviewed and validated. Mechanism of injury, hand dominance and occupation were noted. Initial, post reduction, one week, 6 week and one year x-rays were taken. The volar and dorsal shortening, tilt and angulation were recorded. Any operative intervention or complication was noted. At one year follow up functional testing was performed including range of movement. This tested for grip strength, multiple postional strengths and a functional score looking at activities of daily living. Results: Prediction of functional outcome was significantly associated with age, volar communition, dorsal angulation and pain. The grip strength after a distal radial fracture is significantly stronger in dominant side fractures compared with non dominant, in younger patients and those without dorsal communition. We also showed that fractures that are most likely to malunite show a significantly poorer functional outcome and weaker grip strength. Conclusion: This study identifies factors that predict the functional outcome in Distal Radial fractures. Although many assumptions are made that certain fractures lead to poorer results this has rarely been shown in such a large, diverse group of DRFs. In an age where patients and practitioners strive to ever increasing levels of knowledge this study allows us to counsel patients in their likely functional outcomes more accurately

The best surgical treatment of lateral epicondylitis remains uncertain. Recently radiofrequency microtenotomy (RFMT) has been proposed as a suitable surgical treatment. We aim to compare open release with RFMT and present the results of our randomised controlled trial. Patients with symptoms of tennis elbow for at least 6 months who had failed to respond to conservative management were included in the trial. They were randomised to open release or RFMT. Outcome measures included grip strength, pain and DASH scores. 41 patients were randomised, 23 to RFMT and 18 to open release, 2 patients withdrew from the study. Our results show that both treatments give a significant benefit at all time points for DASH and pain scores, but only open release gives a significant improvement in grip strength. Comparing the two treatments the only significant difference is the open group have better pain scores at 6 weeks, but this is not seen at later follow up. In conclusion both groups have shown benefit from the treatments, but one is not shown to be clearly superior

Introduction: We conducted a prospective study on 29 patients comparing the medium-term outcome between intramedullary nail fixation and plate fixation in paediatric forearm fractures. Materials and Methods: The criteria were patients who had a nail (10) or plate fixation (19) for a single or both bones forearm fracture between 2004 and 2006. All these patients were recalled following ethical approval for assessment of their grip strength using a hand dynamometer, forearm and elbow range of movements, scar assessment, POSNA outcome questionnaire and new radiographic views of the forearms. Results: Mean age of 10.4 years for both groups (4–16), All fractures were caused by low velocity falls. Grip strength is reduced in 83% of patients, comparable in both groups. Elbow flexion is more reduced in the plating group but more reduction in extension in the nailing group. The reduction in forearm pronation (69% of patients) and supination (61%) were comparable in both groups. Using the ‘Manchester scar proforma’; the plating group scored worse with 14/21; nail 11/21. ‘POSNA outcome questionnaire’ score showed the nailing group had 90% excellent or good result and plating group 74%. The moderate and poor POSNA outcome (26% plate, 10% nail) were associated with pain, restricted rotation, bad scarring and difficulty lifting heavy objects. Nails were removed after bony healing but all plates were left in situ. Complete remodeling of forearm bones were seen in all radiographs in both groups. One case of non-iatrogenic ulnar nerve injury and two cases of wound infection were noted; all made full recovery. Conclusion: The medium-term outcome at 2.5 years following either fixation method is generally comparable and good. The obvious differences were; a higher (better) POSNA score in the nailing group, larger scar formation in plating, elbow extension restriction in nailing and elbow flexion restriction in plating group. Factors that were comparable were grip strength, forearm rotation and radiographic remodeling and outcome

Tennis elbow (lateral epicondylitis) is a common upper limb condition, possibly resulting from angiofibroblastic degeneration. Conservative treatment comprises corticosteroid injections, rest and splints, however, occasionally surgery is necessary. Recent data comparing Botulinum Toxin Type A (BTX-A) (Botox®, Allergan Inc, Irvine, CA) with surgery suggested BTX-A is effective in treating resistant tennis elbow by providing temporary, reversible paralysis of affected muscle, thereby alleviating tensile forces and allowing tissue healing. This double-blind, randomised, controlled trial compared BTX-A with placebo in 40 patients with chronic tennis elbow (> 6 months). Recruited patients were randomised to 50U BTX-A+2mL normal saline or 2mL normal saline (placebo). Injections were administered 5cm distal to the maximal area of lateral epicondyle tenderness. Quality of life (SF-12), pain (visual analogue scale) and grip strength (Jamar dynamometer) were assessed pre- and 3 months post-injection in both affected and non-affected arms. Following BTX-A treatment patients had average 19% improvement in grip strength in the affected arm compared to average 2% for placebo, however, this difference did not reach statistical significance (p=0.08, 95% CI −2.31, 35.64). No difference between the groups was seen for the unaffected arm (BTX-A 4% improvement, placebo 1% improvement). Both groups showed similar improvements in pain assessment and also in quality of life. BTX-A treated-patients demonstrated improved grip strength in the affected arm compared to placebo, however this difference was not statistically significant

This prospective controlled clinical trial compares the outcomes of metacarpophalangeal (MCP) arthroplasty in rheumatoid arthritis patients using the Swanson (S) and NeuFlex (N) MCP implants. Forty hands (thirty-seven patients) were randomised and evaluated preoperatively and at one year following MCP arthroplasty in digits two to five for range of motion (ROM; active and passive extension and flexion), ulnar drift and grip strength. Both implants restored extension and corrected flexion deformities. There was no significant difference in extension of all digits (summed) between the NeuFlex and Swanson implants (N: −20.8°; S: −13.8°; p=0.29). The NeuFlex implant, which is pre-flexed at 30°, preserved more flexion at the MCP joint than the Swanson implant in all digits (summed) (N:74.5°; S:55.8°; p=0.005), with the greatest difference observed in the fifth digit (N:69.6°; S:48.7°; p=0.009). The total arc of motion improved in all digits, with no significant differences between the Neu-Flex and Swanson groups in the second through fourth digits (N:53.8°; S:43.8°; p=0.154); a significantly greater improvement was observed in the NeuFlex group for the fifth digit (N:53.3°; S:42.5°; p=0.028). Both implants corrected ulnar drift deformity, while neither led to loss of grip strength. Hand function as measured by Sollerman score and Michigan Hand Questionnaire (MHQ) improved significantly in both groups (p=0.0119, p< 0.0001, respectively) with no significant difference between the Swanson and NeuFlex implants, except for MHQ function, aesthetics, and overall scores, which demonstrated superiority of the Swanson. Overall, there was a significant improvement in the range of motion, deformity and grip strength following MCP arthroplasty for the full patient group. While both implants restored similar amounts of extension, the NeuFlex implant maintained greater flexion and total range of motion, with the greatest difference in the fifth digit. The Swanson implant had better MHQ function and aesthetics subscores

Objective: Complex hand function problems in patients with rheumatic diseases may require the expertise of physicians and health professionals from multiple disciplines. The aim of the present study was to describe the characteristics, management strategies and outcomes of patients with rheumatic diseases who were referred to a multidisciplinary hand clinic. Methods: All consecutive patients with complex hand function problems who were referred to a multidisciplinary hand clinic including a rheumatologist, an orthopaedic surgeon, a rehabilitation specialist, an occupational therapist and a physical therapist were included. Of all patients, sociodemographic characteristics, general disease characteristics, the most troubling impairments and limitations regarding hand function and deformities were recorded at baseline. The following measures of hand function were assessed at baseline and 3 months after treatment: the Sequential Occupational Dexterity Assessment (SODA), the Michigan Hand Outcomes Questionnaire (MHQ), the hand/finger function subscale of the Arthritis Impact Measurement Scales (AIMS), grip strength (Jamar dynamometer) and pain (visual analogue scale, VAS, 0–10 cm). Results: Over a period of 28 months 69 patients were included. Basic characteristics, characteristics of hand function, impairments and limitations that were most frequently mentioned as well as the advised management strategies were recorded. In 38/54 patients (70%) the advised treatment was executed and 33 of them completed the follow-up assessment. Conclusion: The most frequently mentioned impairments and limitations of patients with rheumatic diseases and hand function problems pertain to grip ability and grip strength, pain and shaking hands. Management advices, including conservative and surgical treatment, are followed by two-thirds of the patients. On average, patients who are treated improve significantly with respect to grip strength and overall hand function as measured by a questionnaire

Background: A recent study found that after median term follow-up disability correlated with pain rather than the limited residual impairments in motion and strength. We studied impairment and disability an average of twenty-one years after injury in a cohort of Dutch patient, with the hypothesis that both impairment and disability would be lower in patients that were skeletally immature at the time of injury. Methods: Seventy-one patients were evaluated an average of 21 years after injury. The majority of the 35 skeletally immature patients were treated conservatively with closed reduction and cast immobilization and the majority of the 36 skeletally mature patients were treated with plate and screw fixation. Objective evaluation included radiographs and measurements of range of motion and grip strength. Questionnaires were used to measure arm-specific disability (Disabilities of the Arm, Shoulder and Hand: DASH), misinterpretation or over interpretation of pain (Pain Catastrophizing Scale-PCS-), and depression (CES-D). Multivariable analysis of variance and multiple linear regression were used to compare patients that were skeletally mature and immature at the time of injury and to identify predictors of arm-specific disability (SPSS 17.0, SPSS inc., Chicago). Results: There were 44 men and 27 women with a an average age of forty-one at time of follow-up (range, 20 to 81). Fractures were classified as AO/OTA-type A3 in 46 patients (simple), B3 in 18 (including wedge fragment) and C fractures in 7 patients (comminuted). The average DASH score was 8 points (0 to 54) and 73% reported no pain. Both rotation and wrist flexion/extension were 91% of the uninjured side; grip strength was 94%. There were small, but significant differences in rotation (151 versus 169 degrees, p=0.004) and wrist flexion/extension (123 versus 142 degrees, p=0.002), but not disability between skeletally mature and immature patients. The best predictors of DASH score were nerve damage, pain and grip strength, explaining 56% of the variation in DASH scores. Disability did not correlate with depression or misconceptions about pain. Conclusions: Twenty-one years after initial fracture, both skeletally immature and mature patients have limited impairment (averaging over 90% motion and grip strength) and disability after non operative and operative treatment respectively. Patients that were skeletally immature at the time of injury had better motion, but comparable disability. Disability correlated with pain rather than motion, but did not correlate with psychosocial measures

Purpose: It is known from the literature that gripping, which is commonly used in various work-related, sport-related, and daily activities, activates both wrist extensors and flexors. Pain aggravation occurs during grip due to over-exertion of the extensor muscle group in lateral epicondylitis and grip strength is reduced. Of grip strength studies, few studies have simultaneously investigated muscular response using electromyography as a method of monitoring muscular fatigue or muscular activity of forearm muscles. The fatigability and activity of wrist antagonistic muscles in patients with lateral epicondylitis has not been previously investigated. Methods: 16 tennis elbow patients (Tennis Elbow Group) and 16 healthy volunteers (Control Group) were participated in this study. In both groups, local muscular fatigue and muscular activity were measured for 3 forearm muscles contributing to the wrist extension and 2 muscles contributing to the wrist flexion using EMG and during gripping at 50% maximum voluntary contraction (MVC). Fatigability and activity of muscles then were compared between control and tennis elbow groups. Results: Grip strength was significantly lower in tennis elbow group than that in control group (p < 0.05). Median frequency (MDF) and root mean square (RMS) of electromyographic signals were used as parameters to measure muscular fatigue and muscular activity, respectively. Further analysis showed no significant difference in the fatigability of forearm muscles between two groups. The activity of Extensor Carpi Radialis (ECR) showed statistically significant reduction in tennis elbow group compared to the control group (p < 0.05). Conclusion: This is the first study to simultaneously investigate the fatigability and activity of the forearm antagonistic muscle groups in patients with lateral epi-condylitis. The fact that ECR showed similar level of muscular fatigue to other muscles despite decreased muscular activity may indicate of higher fatigability of this muscle in tennis elbow. Furethermore, decreased muscular activity of ECR may be a part of mechanism to protect the muscle from further injury in tennis elbow patients

Fractures of the distal radius are the most common bony injuries in the upper extremity, and many treatment Methods: have been described in the literature. External fixation remains a highly versatile method to treat many fracture types involving the distal radius. The primary indications for external fixation include reduction of unstable extra-articular fractures and most intra-articular fractures. The use of adjuvant pinning or mini open procedures can be used when external fixation inadequately reduces the joint line alone, especially with central depressions and highly comminuted injuries. The ease of use of the implants and successful track record make it an extremely versatile tool for treating complex fractures of the distal radius. Purpose: To compare 2 Methods: of surgical treatment for displaced intra-articular fractures of the distal radius: open reduction and internal fixation with dorsal plating (Pi Plate; Synthes, Paoli, PA) versus external fixation with o without K-wires. Methods: We compare a retrospective study about AO type C intra-articular distal radius fractures. The fist group (40 patients) is treated with open reduction and internal fixation with DVR plate ande the second group (65 pacients) is treated with external fixation and K-wires and mini-open reduction. Objective, subjective, and radiographic outcomes were assessed at 2 weeks, 4 to 6 weeks, 10 to 12 weeks, 6 months, and 1- and 2-year intervals. The minimum follow-up period was 6 months; the average follow-up period was 18 months. The principal outcome analyzed was Jakim store that included pain, grip strength, range of motion, complications, and radiographic parameters. The groups were equal with respect to age, gender and fracture subtype. Results: No significant difference was found in the Jakim store outcome. The volar plate group, howevwe, showed a similar complication rate when compared with the external fixator group. The plate group also had similar levels of pain at 1 year when compared with the external fixator group. The external fixator group showed an average grip strength of 92% compared with the normal side and 86% in the volar plate group. Conclusions: At midterm analysis the volar plate group showed a significantly higher complication rate compared with the external fixator group; therefore enrollment in the study was terminated. The volar plate group also showed statistically significant higher levels of pain, and weaker grip strength. Based on these results we can recommend the use of volar plates in treating complex intraarticular fractures of the distal radius

Surgical results following proximal row carpectomy modified with proximal capitate resection and dorsal capsule interposition are presented. A consecutive cohort of thirteen patients was operated upon, and outcomes measured by radiograph, physical examination and DASH questionnaire. AROM values of 50° to 105° for the flexion/extension arc, restoration of grip strength to 72% of the contralateral extremity, and an improved functional outcome can be expected; and patients’ perceptions of functional outcome, as measured by the DASH, are significantly improved as early as six weeks. The results of PRC with interposition for stages II and III SLAC wrist were uniformly favorable. Eaton has described two modifications to the proximal row carpectomy (PRC) procedure: partial capitate resection and dorsal capsular interpositional arthroplasty. The objective is to enlarge the radiocarpal interface to form a broad mobile pseudoarthrosis that would disperse compressive forces across the wrist more effectively. We present the first consecutive cohort of patients (n=13) who have undergone this procedure,. We extend the indications for PRC in this series to include those wrists with stage III SLAC deformity; approximately 67% of wrists had capitolunate arthritis. AROM values of 50° to 105° for the flexion/extension arc, restoration of grip strength to 72% of the contralateral extremity, and an improved functional outcome can be expected from PRC with dorsal capsular interpositional arthroplasty. Patients’ perceptions of functional outcome, as measured by the DASH, are significantly improved as early as six weeks following the procedure. Mean flexion/extension arc achieved was 86° (range, 50° to 105°). Radial deviation averaged 13° (range, 10° to 20°), and ulnar deviation averaged 21° (range, 15° to 25°). Grip strength averaged 72% of the contralateral extremity. The mean decline in the revised carpal height ratio was 24%. The mean DASH score was 20.8 (range, 10 to 29). Visual analog pain improved from 9.25 to 2.67 on average, with one patient reporting no pain with heavy exertion. Patients were evaluated by active range of motion ; grip and pinch strength; radiographs; subjective analog pain; and DASH questionnaire

Introduction: Distal radial fractures are common and sometimes surgery is necessary. The volar locking plate has become the standard solution in the last years in many hospitals but the method is unproven scientifically. In this series we have retrospectively followed our early cases of volar plates. Patients and Material: We identified all 68 patients (44 women and 9 men) at Lund University Hospital undergoing surgery using the TriMed. ®. volar fixed-angle plate for distal radius fracture between January 2006 and December 2007. The mean age was 57 years (20–84). The patients were contacted by mail and sent a Quick-DASH, a validated outcome questionnaire. Eleven patients were excluded according to the protocol due to having another concomitant or bilateral fractures or other complicating conditions like stroke or hemiparesis or psychiatric disorder. 53 of the remaining 57 patients completed the Quick-DASH and plotted their subjective function, pain at rest and at activity as well as the cosmetic appearance on a 0–100 mm visual analogue scale (VAS). 50 patients came to the hospital for an additional radiogram and measurement of the range of motion (goniometer) and grip strength (JAMAR). Results: Quick-DASH median was 4,5 (range 0–80), and mean 14. Seventeen (32%) of the patients had zero for VAS at rest. Ten (19%) had a DASH value of more than 30 implicating a less than satisfying result. Range of motion in de fractured wrists were 91% of the non-fractured and the grip strngth 82% of the contralateral. Discussion: In the present study the patients regained near full function in their fractured wrists after the operation with the volar locking plate. The ROM of the fractured wrists was 91% of the ROM of the non-fractured wrists, whereas the grip strength of the fractured wrists was 82% compared to the contralateral side. These data are excellent and similar both to previous own results as well as other published studies. The results of the Quick-DASH questionnaire, representing the subjective perception of the outcome, indicate that the patients are satisfied. Seventeen of the 53 patients scored zero on the DASH, suggesting a full recovery without any sequelae. In the population the median value is 2,5 (Abramo 2008). Ten of the patients had a DASH score over 30, indicating substantial subjective limitations in the daily life. Interestingly, there appears to be little or no correlation between high DASH scores and impaired ROM or grip strength. However, we noted that patients with high DASH scores also tended to score high in the VAS-question regarding subjective pain at activity. It was further noted that the patients with a DASH over 30 had a delay between injury and operation for a mean of 10,3 days (1–19 days) between injury and operation, compared to the patients with a DASH score below 30 who had a mean of 5,6 days (2–16 days) delay

Background: Distal radius fractures are among the most common fractures, consisting of about 1/6 of all fractures shoving up at the ER. Many times surgical treatment is indicated. However which type of operation to chose is not known. The standard operative treatment has been external fixation but more modern techniques for internal fixation have become increasingly popular. Our aim was to evaluate if internal fixation is beneficial for the patients. To do this we did this randomized study. Material and methods: Between May 2002 and March 2005 a randomized study between closed reduction and external fixation versus open reduction and internal fixation with the TriMed® system was performed in 42 consecutive patients. 29 were women and 13 were men in the ages between 20 and 63 with a mean age of 48 years. 20 were randomized to closed treatment and 22 to open treatment. Patients were followed with clinical examination, radiographs, examination of range of movement and grip strength and outcome measured by DASH for one year. Results: DASH-scores showed no statistical significant differences between the groups neither early at seven weeks (32 in the open group an 29 in the closed) nor late at one year (9 vs. 13) postoperatively. Range of movement in flexion and extension was better in the internal fixation group at 5 weeks (45 degrees vs. 67) degrees postoperatively but this difference disappeared at one year (121d egrees in both groups). Grip strength was significantly better for the TriMed group at 5 weeks (32% of the opposite side vs. 8% in the external fixation group) and 7 weeks (47% vs. 34%) and at one year (78% vs. 90%) postop. Range of movement in forearm rotation was significantly better in the open group during the whole follow up (126deg. vs. 101deg. at seven weeks and 149 vs. 133 at one year). There were three cases of redislocation in the external fixation group. They were all later treated with osteotomy. However there were 15 cases of minor complications in the open group compared to 9 cases in the closed group. The minor complications were mainly consisting of transient tingling of the radial nerve in the open group and skin adherences in the closed group. Conclusion: Open reduction and internal fixation for distal radial fractures give better result regarding motion and grip strength than External fixation but there is no difference in subjective outcome. Complications are common in both groups but these are often minor non lasting complications. However malunion is more common with external fixation

Purpose: The cruciate four-strand flexor tendon repair technique has been advocated for its ease of use and biomechanical strength. However, the in vivo efficacy of the cruciate 4-strand repair has not been reported; no has this method of repair been assessed for its ability to allow for an early active motion rehabilitation protocol. The purpose of this study was to report early clinical results using the cruciate 4-strand repair for proximal zone I and zone II flexor tendon lacerations. Method: Thirty-five digits in thirty-one patients had proximal zone I (3 digits) or zone II (32 digits) flexor tendon lacerations which were repaired using the cruciate 4-strand technique and an epitendinous state. Average patient age was 30.8 years (range 9.7–63.7). An early active motion rehabilitation protocol was initiated an average of 1.5 days following tendon repair. The supervised therapy program was continued for 12 weeks post-operatively. Assessment of total active motion (TAM), as well as PIP and DIP TAM, grip strength, and joint contractures were recorded at 3 months and at 6 months or greater post-operatively. Functional assessments (using the Strickland and American Society of Surgery for the Hand criteria) were performed for each patient at 3 and 6 month intervals. Results: All patients were followed for a minimum three-month period. At 3 months postoperatively, there were 16 excellent, 7 good, 6 fair, and 6 poor results by the Strickland criteria, and 12 excellent, 15 good, 7 fair, and 1 poor by the ASSH criteria. Total active motion averaged 225° (±44°), PIP and DIP motion averaged 136° (±40°). Grip strength was available for 17 patients and averaged 60% of the contralateral, uninvolved hand. By 6 months or greater postoperatively there were 18 digits available for follow-up. There were 15 excellent results and 3 good results by the Strickland criteria, and 11 excellent and 7 good results by the ASSH criteria. Six patients had PIP contractures averaging 11° (range 3–15°), and two patients had DIP contractures averaging 13° (range 5–20°). Total active motion averaged 257° (±22°), and PIP and DIP motion averaged 166° (±22°). Grip strength was available on 14 patients and averaged 91% of the contralateral hand. To date, of the patients followed up to 6 months or longer, there have been no ruptures, no re-operations for tenolysis, and no loss of motion. Conclusion: Early clinical results using the cruciate 4-strand suture technique for flexor tendon repair have demonstrated outcomes equivalent or superior to other methods. The relative simplicity of the technique, with biomechanical strength properties facilitating a modified early active motion rehabilitation protocol, may make this method of repair attractive. Further clinical studies will need to be performed to determine the long-term efficacy of this method of tendon repair

There is no consensus on the benefit of arthroscopically assisted reduction of the articular surface combined with fixation using a volar locking plate for the treatment of intra-articular distal radial fractures. In this study we compared the functional and radiographic outcomes of fluoroscopically and arthroscopically guided reduction of these fractures. Between February 2009 and May 2013, 74 patients with unilateral unstable intra-articular distal radial fractures were randomised equally into the two groups for treatment. The mean age of these 74 patients was 64 years (24 to 92). We compared functional outcomes including active range of movement of the wrist, grip strength and Disabilities of the Arm, Shoulder, and Hand scores at six and 48 weeks; and radiographic outcomes that included gap, step, radial inclination, volar angulation and ulnar variance. . There were no significant differences between the techniques with regard to functional outcomes or radiographic parameters. The mean gap and step in the fluoroscopic and arthroscopic groups were comparable at 0.9 mm (standard deviation. (sd). 0.7) and 0.7 mm (. sd. 0.7) and 0.6 mm (. sd. 0.6) and 0.4 mm (. sd. 0.5), respectively; p = 0.18 and p = 0.35). . Arthroscopic reduction conferred no advantage over conventional fluoroscopic guidance in achieving anatomical reduction of intra-articular distal radial fractures when using a volar locking plate.

We present the results of a bi-centre, retrospective study examining the clinical, functional and radiological outcomes of distal radius fracture fixation with the Aptus locking plates and Tri-Lock® variable angle locking screws. We assessed 61 patients with distal radius fractures with a minimum of six months follow-up. Functional assessment was made using the DASH score. We measured wrist range of movement and grip strength, and reviewed radiographs to assess restoration of anatomy, fracture union and complications. All fractures united within six weeks. Mean ranges of movement and grip strength were only mildly restricted compared to the normal wrist. The mean DASH score was 18.2. Seven patients had screws misplaced outside the distal radius although 3 of these remained asymptomatic. Five other patients developed minor complications. Variable angle locking systems benefit from flexibility of implant positioning and may allow enhanced inter-fragmentary reduction for accurate fixation of intra-articular fractures. However, variable-angle systems may lead to increased rates of screw misplacement

Advanced osteoarthritis of the wrist or the distal articulation of the lunate with the capitate has traditionally been treated surgically by arthrodesis. In order to maintain movement, we performed proximal row carpectomy with capsular interposition arthroplasty as an alternative to arthrodesis in eight patients with advanced arthritis and retrospectively reviewed their clinical and radiographic outcomes after a mean follow-up of 41 months (13 to 53). The visual analogue scale (VAS) for pain at its worst and at rest, and the patient-rated wrist evaluation score improved significantly after surgery, whereas ranges of movement and grip strength were maintained at the pre-operative levels. Progression of arthritis in the radiocapitate joint was observed in three patients, but their outcomes were not significantly different from those without progression of arthritis. Proximal row carpectomy with capsular interposition arthroplasty is a reasonable option for the treatment of patients with advanced arthritis of the wrist

The purpose of this study was to evaluate treatment results following arthroscopic triangular fibrocartilage complex (TFCC) debridement for recalcitrant ulnar wrist pain. According to the treatment algorithm, 66 patients (36 men and 30 women with a mean age of 38.1 years (15 to 67)) with recalcitrant ulnar wrist pain were allocated to undergo ulnar shortening osteotomy (USO; n = 24), arthroscopic TFCC repair (n = 15), arthroscopic TFCC debridement (n = 14) or prolonged conservative treatment (n = 13). The mean follow-up was 36.0 months (15 to 54). Significant differences in Hand20 score at 18 months were evident between the USO group and TFCC debridement group (p = 0.003), and between the TFCC repair group and TFCC debridement group (p = 0.029). Within-group comparisons showed that Hand20 score at five months or later and pain score at two months or later were significantly decreased in the USO/TFCC repair groups. In contrast, scores in the TFCC debridement/conservative groups did not decrease significantly. Grip strength at 18 months was significantly improved in the USO/TFCC repair groups, but not in the TFCC debridement/conservative groups. TFCC debridement shows little benefit on the clinical course of recalcitrant ulnar wrist pain even after excluding patients with ulnocarpal abutment or TFCC detachment from the fovea from the indications for arthroscopic TFCC debridement.

Radial osteotomy is currently advocated for patients with Lichtman’s stages II and IIIA of Kienböck’s disease; its place in the treatment of patients with stage IIIB disease remains controversial. The purpose of this study was to evaluate the medium-term results of this procedure and to compare the outcome in patients with stage IIIB disease and those with earlier stages (II and IIIA). A total of 18 patients (18 osteotomies) were evaluated both clinically and radiologically at a mean follow-up of 10.3 years (4 to 18). Range of movement, grip strength and pain improved significantly in all patients; the functional score (Nakamura Scoring System (NSSK)) was high and self-reported disability (Disabilities of Arm, Shoulder and Hand questionnaire) was low at the final follow-up in all patients evaluated. Patients with stage IIIB disease, however, had a significantly lower grip strength, lower NSSK scores and higher disability than those in less advanced stages. Radiological progression of the disease was not noted in either group, despite the stage. Radial osteotomy seems effective in halting the progression of disease and improving symptoms in stages II, IIIA and IIIB. Patients with less advanced disease should be expected to have better clinical results

An anaesthetist recently remarked that orthopaedic surgeons are ‘twice as strong as an ox but half as smart’. We set out to ascertain if this had any evidence basis by conducting an observational study. We compared 36 male orthopaedic surgeons to 40 male anaesthetists across 3 hospitals to ascertain if there was a significant difference between the two groups in terms of Intelligence Quotient (IQ) and strength. We tested the IQ of each doctor using an official MENSA IQ test. We assessed the strength as reflected by the grip strength using a hand-grip dynamometer. Un-paired t-tests were used to assess statistical significance. Orthopaedic surgeons had a significantly greater mean grip strength 47.25Kg (SD=6.95) compared to anaesthetists 43.83Kg (SD=7.57) (p=0.04). The mean IQ of orthopaedic surgeons was also significantly greater at 105.19 (SD=10.85) than anaesthetists at 98.38 (SD=14.45) (p=0.02). Furthermore, the IQ of orthopaedic surgeons seems to increase with increasing age and seniority (an IQ jump of 5 IQ points from Registrar to Consultant). We have concluded that this proverb should be revised to orthopaedic surgeons are as strong as an ox and twice as smart, although further studies are advocated to ascertain the IQ of Ox

Aims. We present the clinical and radiographic outcome of 81 children with Gartland type I to III supracondylar humeral fractures at a minimum follow-up of ten years (mean 12.1 years; 10.3 to 16.1) following injury. Patients and Methods. The clinical and functional outcomes are compared with normal age- and gender-matched individuals. The population-based study setting was first identified from the institutional registries; the rate of participation was 76%. Controls were randomly selected from Finnish National Population Registry. Results. According to Flynn's criteria, most fractures (75.3%) resulted in a satisfactory (“good or excellent”) outcome. Satisfactory recovery was achieved in 75.0% of type I fractures treated by closed splinting (p = 0.013). Type II fractures were associated with both satisfactory (57.7%) and unsatisfactory (42.3%) results, regardless of the type of treatment, although the numbers were small in the sub groups. Most type III fractures were treated operatively, and most (76%) had a satisfactory outcome according to Flynn’s criteria (p = 0.015). Compared with none among the normal subjects, flexion of the elbow was reduced by >  10° at long-term follow-up in 20 cases (24.7%, p < 0.001) and 9 (11.1%) had a reduced flexion of > 15° (p = 0.004). In patients who had sustained a type III fracture, the carrying angle was decreased by 35.7% (from 9.8° to 6.3°; p = 0.048). All patients achieved an excellent Mayo Elbow Performance Score (mean 96.4 points). Conclusion. The long-term outcome of extension-type supracondylar humeral fractures is generally good, but not exclusively benign, with the potential for long-term pain and ulnar nerve sensitivity, and a decrease in grip strength and range of movement in type II and type III fractures. Bony remodelling cannot be relied upon to correct any residual deformity. In particular, type II fractures have impaired long-term recovery and justify individual consideration in their treatment.

Aim:. To assess the clinical outcomes of patients that had perilunate or lunate dislocations treated with either open or closed reduction and wiring without repair of the scapholunate interosseous ligament (SLIL). Background:. Current literature states that acute perilunate dislocations should be treated with open reduction and repair of the dorsal scapholunate ligament. This is to prevent dissociative carpal instability and potential long term degenerative arthrosis. Methods:. A retrospective review of patients who sustained a perilunate or lunate dislocation, with no associated radial or carpal fracture was conducted. All were treated by reduction and percutaneous wiring without repair of the SLIL. Patients were examined and data was collected regarding patient's pain, range of motion, grip strength, instability and return to work. All patients had a Mayo wrist score. Pre and post-surgical radiographs were assessed and the scapholunate distance, scapholunate angle and the radiolunate angle were measured. The presence of a high riding scaphoid and osteoarthritis was recorded. Results:. A total of 13 patients were included in the study, with an average follow up of 32 months. 92% of patients had no pain in their wrist at final follow up. Range of movement was 78% of the normal side. 70% of patients returned to work. 92% of patients had no clinical wrist instability. Grip strength was 82% of the opposite side. Radiographic assessment showed an average scapholunate distance of 2.6 mm, a scapholunate angle of 65° and radiolunate angle of 11°. One of the 13 patients had a high riding scaphoid. 23% of patients had arthritic changes of the carpus on plain radiographs. Of the 13 patients, 3 had excellent mayo scores, 4 good, and 6 fair. No patients had poor scores. Of the 13 patients reviewed 10 returned to work, those that did not were not able to due to other disabilities acquired at the time of their accident. Conclusion:. Acute management of perilunate dislocations with reduction and percutaneous wiring without repair of the SLIL, resulted in the majority of patients having a pain free, stable, mobile wrist with an above average Mayo wrist score and no arthritic change on radiographic assessment

One hundred and sixty-two patients with a diagnosis of scapholunate instability underwent a modified Brunelli procedure over a 7 year period. One hundred and seventeen were assessed with the help of a questionnaire and, of these, 55 patients attended for clinical evaluation. The mean follow-up was 4 (1-8) years. There were 72 patients with dynamic scapholunate instability and 45 patients with static instability. The average age was 38 years. There were 50 males and 67 females. 77 (62%) patients had no to mild pain with a mean visual analogue score of 3.67 (SD=2.5)). The loss in the arc of flexion-extension was due to a reduced range of flexion (mean 31% loss), while 80% of extension was maintained, compared with the contralateral side. The grip strength on the operated side was reduced by 20% of the non-operated side. There was no statistically significant difference (p>0.05) in the range of movement or the grip strength between the static and dynamic group or the claims and non-claims group. Ninety (79%) patients were satisfied with the result of the surgery (good to excellent) and 88% of the patients felt that they would have the same surgery again. We feel that these results compare favourably with the early results published from this unit and recommend this procedure for dynamic and static scapholunate instability

Numerous surgical techniques have been proposed and described in the treatment of Kienbock's disease. The objective of this systematic review was to assess the current evidence and trends in the management of Lichtman Stages IIIA and IIIB. We performed a literature search using the Medline, Embase, and Cochrane databases to identify studies evaluating treatment outcomes in Stages IIIA and IIIB of Lichtman's Classification. We included studies between 2008 and 2018, and studies with Sackett levels one to four inclusively. We excluded studies that included skeletally immature patients, non-English papers, other hand diseases, and those without evidence of significance testing. We evaluated the quality of each included study using the Structured Effectiveness Quality Evaluation Scale (SEQES) and our outcomes of interest included Pain, ROM, Grip Strength, and Functionality. We identified 1489 titles from the various databases. 83 papers remained after the subtraction of duplicates and abstract review. Following full-text review of the remaining 83 papers, 43 more studies were excluded and 40 papers met the criteria for SEQES assessment. There were six low-quality papers and 34 moderate-quality papers. Meta-analysis was not possible due to the variability in how outcomes were reported. A variety of surgical options were presented including decompressions, joint-levelling procedures, revascularization techniques, fusions, arthroplasty and novel combinations of these techniques. These were mainly retrospective and/or cohort studies. Most of these papers had small sample sizes and required further studies. Nonetheless, all of these treatment modalities were shown to offer pain relief and some degree of return of function ranging from minimal improvement to return to normal daily functions. This systematic review has revealed a significant weakness in the literature and a lack of strong evidence in the treatment of Stages IIIA and IIIB of Kienbock's disease. The unknown etiology of this disease and its rarity make it very difficult to produce randomized controlled trials and appropriately-sized studies. As such, there is currently insufficient data to determine a superior treatment modality from another. Furthermore, the fact that most, if not all, surgical interventions produced positive results may also be a consequence of publication bias

Background. Since its first description, the pathology, natural history and treatment of lateral epicondylitis have remained controversial. For those who fail conservative management, surgery remains an option. The optimal method of surgery remains debatable and is further confounded by a relative lack of long-term follow up studies. Material and methods. This study describes a previously unpublished surgical technique and presents its long term results. Patients undergoing this open technique were reviewed using the HSS-1 and Mayo elbow performance assessment tools as well as having grip strength and subjective outcome recorded. Results. From June 1986 to December 2001 inclusive, 158 consecutive patients (171 elbows) underwent surgery in a single surgeon series. They were followed up to a mean of 9.8 years. The mean age of the group was 42 years and 86.7% of patients were available for follow up. Subjectively, 94.6 % were good to excellent with 92.6-94.0% good to excellent using the HSS-1 and Mayo scores respectively. No differences were noted in grip strength. No patient required revision surgery. Discussion/Conclusions. This repeatable open technique offers excellent results with low complications at a mean follow up of 9.8 years. These results compare favourably in terms of numbers followed up, length of follow up and outcome and offer strong evidence of its efficacy

We reviewed 10 patients with symptomatic malunion of a carpal scaphoid fracture. All had displacement with dorsiflexed intercalated segment instability, and suffered from pain, restricted range of movement at the wrist and decreased grip strength. The restriction of flexion-extension and the decreased grip strength correlated with the severity of the DISI deformity. Seven patients had a corrective osteotomy, using an anterior wedge-shape bone graft with internal fixation by Herbert screw, and all had satisfactory results. We believe that symptoms associated with scaphoid malunion are related to consequent carpal deformity

We systematically reviewed all the evidence published in the English language on proximal interphalangeal joint (PIPJ) replacement, to determine its effectiveness on the function of the hand and the associated post-operative complications. Original studies were selected if they reported clinical outcome with a minimum of one year’s follow-up. Quality was assessed using the Cowley systematic review criteria modified for finger-joint replacements. Of 319 articles identified, only five were adequately reported according to our quality criteria; there were no randomised controlled trials. PIPJ replacements had a substantial effect size on hand pain of -23.2 (95% confidence interval (CI) -27.3 to -19.1) and grip strength 1.2 (95% CI -10.7 to 13.1), and a small effect on range of movement 0.2 (95% CI -0.4 to 0.8). A dorsal approach was most successful. Post-operative loosening occurred in 10% (95% CI 3 to 30) of ceramic and 12.5% (95% CI 7 to 21) of pyrocarbon replacements. Post-operative complications occurred in 27.8% (95% CI 20 to 37). We conclude that the effectiveness of PIPJ replacement has not been established. Small observational case studies and short-term follow-up, together with insufficient reporting of patient data, functional outcomes and complications, limit the value of current evidence. We recommend that a defined core set of patients, surgical and outcome data for this intervention be routinely and systematically collected within the framework of a joint registry

Aims. Between 2002 and 2011, 81 patients with a traumatic total brachial plexus injury underwent reconstruction by double free muscle transfer (DFMT, 47 cases), single muscle transfer (SMT, 16 cases) or nerve transfers (NT, 18 cases). . Methods. They were evaluated for functional outcome and quality of life (QoL) using the Disability of Arm, Shoulder and Hand questionnaire, both pre- and post-operatively. The three groups were compared and followed-up for at least 24 months. Results. The mean shoulder abduction and flexion were comparable in all groups, but external rotation was significantly better in the DFMT group as were range and quantitative power of elbow flexion. Patients who had undergone DFMT had reasonable total active finger movement and hook grip strength. All groups showed improvement in function at a level greater than a minimum clinically important difference. The DFMT group showed the greatest improvement. Discussion. Patients in the DFMT group had a better functional outcome and QoL recovery than those in the NT and SMT groups. . Take home message: Double free muscle transfer procedure is capable of restoring maximum function in patients of total brachial plexus palsy. Cite this article: Bone Joint J 2016;97-B:209–17

Ostoearthritis of the trapeziometacarpal (TMC) joint, the key joint in thumb opposition, is one of the most common diseases involving the hand, especially among middle-aged and elderly women, and can seriously impair overall hand function. Material and Methods: The purpose of this study was to analyze our experience in the treatment of trapezio-metacarpal (TMC) osteoarthritis with a cemented surface replacement arthroplasty (SR Avantis prosthesis). We did a retrospective study of 34 patients with 43 hands operated on with this technique, with a follow-up evaluation of 36 months. We analyzed the preoperative stage, the postoperative clinical results, measured the radiographic changes found at the end of the study. For outcome, Quick-DASH (Disabilies of the Arm, Shoulder and Hand Score) scores was used. A Jamar dynamometer was used to assess the grip and pinch strengths which showed a 63% of recovering of the grip strength. Overall survival after a mean follow up of 36 months was 93%. At final follow up mean Quick DASH score was 27.4 Radiological review of the surviving joints showed subsidence of trapezial component in 4 joints and further lucencies in 3 joints. However, these patients had good hand function and grip strength. No sign of osteolysis was seen in any of the cases. We found that the radiological findings did not correlate with clinical findings. Satisfaction rate was 26 good to excellent, with 5 fair and 3 poor. Conclusion: The three years results of the SR joint replacement are promising with satisfactory functional outcome despite some radiological findings

Despite the variety of implants or techniques that exist to treat displaced distal radial fractures, the majority fail to provide sufficient stability to permit early functional recovery. However, locking plates have the advantage over other implants in that locking screws add considerably to the overall stability. The aim of this study was to assess the functional outcome of patients with displaced distal radial fractures treated with a volar distal radial locking plate (Synthes). During a two year period, details of 98 patients admitted to our unit with inherently unstable dorsally displaced distal radial fractures treated with volar locking plates were collected prospectively. For the purpose of this analysis, only those patients (55) with unilateral fracture, able to attend the study clinic at 6 months post-injury were considered. Patients were immobilised in wool and crepe for a 2 week period. The group consisted of 15 males and 40 females with an average age of 54 (28 to 83). At 6 months, patients' perceived functional recovery averaged 80%. Objective assessment was considered in relation to the uninjured side: grip strength 73%; pinch strength 83%; palmarflexion 77%, dorsiflexion 80%; radial deviation 74%; ulnar deviation 74%; pronation 93%, and supination 92%. Seven patients complained of symptoms relating to prominent metalwork. Good/excellent early subjective and objective functional recovery was made following open reduction and internal fixation using volar locking plates of dorsally displaced distal radial fractures. We suggest that objective assessment of grip strength and dorsiflexion can be used as a measure of patient perception of function

Hand function was evaluated in 105 patients who had been operated on in early infancy for brachial plexus birth palsy. The mean follow-up after surgery was for 13.4 years (5.0 to 31.5). Fine sensation, stereognosis, grip and pinch strength and the Raimondi scale were recorded. Fine sensation was normal in 34 of 49 patients (69%) with C5–6 injury, 15 of 31 (48%) with C5–7 and in 8 of 25 (32%) with total injury. Loss of protective sensation or absent sensation was noted in some palmar areas of the hand in 12 of 105 patients (11%). Normal stereognosis was recorded in 88 of the 105 patients (84%), whereas only 9 of the 105 (9%) had normal grip strength. The mean Raimondi scale scores were 4.57 (3 to 5) (C5–6), 4.26 (1 to 5) (C5–7) and 2.16 (0 to 5) in patients with total injury. The location of impaired sensation was related to the distribution of the root injury. Avulsion type of injury correlated with poor recovery of hand function

Aims: The aim of this study was to þnd out if undisplaced displaced distal radial fractures require plaster immobilisation. Methods: In this prospective study, undisplaced distal radial fractures were divided into two groups; plaster immobilisation was used for one group while removable volar splint was used for the other group. Follow up was at six weeks, three months and six months. Patients were assessed by clinical examination, grip strength, radiological assessment, EQ-5D and a Short Form 12 questionnaire. Results: At 3 months, no difference was found between the two groups in clinical evaluation, radiological assessment, the functional outcome, grip strength, and visual analogue score for pain. Conclusions: We conclude that undisplaced distal radius fractures can probably be treated with out a plaster cast and put straight into wrist orthosis

We describe a new technique for open reduction, bone grafting and fixation with a single Kirschner wire of unstable fractures of the distal radius. Of the 83 patients treated by this technique, most had regained volar tilt when seen at an average of 13 months after injury. Malunion was seen in 18 patients due either to poor placement of the graft and Kirschner wire or because of both volar and dorsal comminution. Assessment of hand and wrist function showed an average recovery of 63% of mass grip strength with an excellent return of specialised grip strength and range of movement. The advantages of this technique over closed methods include the ability to regain the volar tilt of the distal radius and to achieve reduction at any time before union of the fracture

The Madelung deformity can result in pain and decreased function of the wrist and hand. None of the surgical techniques available has been shown consistently to improve grip strength, range of movement or relieve pain. In this prospective study we have treated 18 patients with the Madelung deformity (25 wrists) by wedge subtraction osteotomy of the radius and shortening of the ulna. Our results show statistically significant improvement in grip strength and range of movement of the wrist and forearm. Pain improved in 80% of the patients and 88% were satisfied with the appearance. One patient had a wound infection and another developed reflex sympathetic dystrophy. Two had some recurrence due to continued growth of the ulna and it is recommended that the procedure be delayed until skeletal maturity, or else combined with epiphysiodesis of the ulna

Introduction: Long-term results of radial osteotomy for Kienbock’s disease seldom are seen in the literature. The purpose of this study was to evaluate its outcome. Material: Fifteen patients submitted to radial osteotomy were followed by a mean period of 9,5 years. Mean age at the time of surgery was 32,1 years. On the basis of the Lichtman classification, one patient had Stage II, eight had Stage IIIA and six had Stage IIIB disease. Methods: Patients were evaluated clinically for pain, grip and range of motion (ROM); radiologically, according to carpal height ratio, Stahl’s index (lunate colapse), and for sclerotic, cystic and degenerative carpal changes. These data were classified according to the Nakamura Scoring System for Kienbock (NSSK). Results: Ten patients are asymptomatic and five have mild pain. ROM improved significantly by 20,8°. When compared with the contralateral wrist, mean range of motion was 78% in flexion and 76% in extension and mean grip strength was 82,3%. Carpal height ratio and Stahl’s index improved, as shown by a mean NSSK of 24,3 (ten Excellent and five Good results). There was no progression to wrist arthritis. Discussion: Pain, ROM and grip strength improved significantly after surgery. Despite the mild radiologic changes, there seems to have been an improvement in inner structure of the ischemic lunate. Conclusions: These results show that Radial Osteotomy is an effective procedure in improving clinical and functional scores, and in preventing wrist arthritis

We prospectively reviewed 14 patients with deficiency of the proximal pole of the scaphoid who were treated by rib osteochondral replacement arthroplasty. Improvement in wrist function occurred in all except one patient with enhanced grip strength, less pain and maintenance of wrist movement. In 13 patients wrist function was rated as good or excellent according to the modified wrist function score of Green and O’Brien. The mean pre-operative score of 54 (35 to 80) rose to 79 (50 to 90) at review at a mean of 64 months (27 to 103). Carpal alignment did not deteriorate in any patient and there were no cases of nonunion or significant complications. This procedure can restore the mechanical integrity of the proximal pole of the scaphoid satisfactorily and maintain wrist movement while avoiding the potential complications of alternative replacement arthroplasty techniques and problems associated with vascularised grafts and salvage techniques

Introduction. The role of in-situ decompression in patients with severe ulnar nerve compression is still controversial. The authors present a prospective study on the results of in-situ decompression in this selected group of patients treated through a mini open incision (4cms) and complete decompression by appropriate patient positioning. Material/Methods. Thirty patients (20 Male/10 Female) with severe degree of nerve compression, confirmed clinically by Dellon's classification and by abnormal Nerve Conduction Study, underwent simple in-situ decompression under general anaesthesia as a day-case procedure. Through a 4cms incision and by moving the elbow the nerve is fully visualised and decompressed. Outcome was measured prospectively at three months and one year using Modified Bishop's score, grip strengths and two point discrimination (2PD). Results/Statistics. The average age of patients were 58.3 (26–87) and dominant hand was involved in 13 patients. Patients showed improvement greater at 1year than at 3 months. There was statistically significant improvement in power (p-0.01) and pinch grip strength (p-0.001) at one year after surgery. According to Modified Bishop's scoring, 24 patients (80%) had good to excellent results at one year follow-up. Of the eight patients with fair results at three months four improved and two detiorated, leading to a total of four poor results (13.3%) at one year follow-up. The 2PD identified the patients with poor or good results according to the Modified Bishop score at three months follow-up. Conclusions. Our results show that the minimally invasive in-situ decompression is technically simple, safe and gives good results in patients with severe nerve compression. The Modified Bishop score and 2PD were more reliable in assessing these patients at follow-up

The Motec cementless modular metal-on-metal ball-and-socket wrist arthroplasty was implanted in 16 wrists with scaphoid nonunion advanced collapse (SNAC; grades 3 or 4) and 14 wrists with scapholunate advanced collapse (SLAC) in 30 patients (20 men) with severe (grades 3 or 4) post-traumatic osteoarthritis of the wrist. The mean age of the patients was 52 years (31 to 71). All prostheses integrated well radiologically. At a mean follow-up of 3.2 years (1.1 to 6.1) no luxation or implant breakage occurred. Two wrists were converted to an arthrodesis for persistent pain. Loosening occurred in one further wrist at five years post-operatively. The remainder demonstrated close bone–implant contact. The clinical results were good, with markedly decreased Disabilities of the Arm Shoulder and Hand (DASH) and pain scores, and increased movement and grip strength. No patient used analgesics and most had returned to work. Good short-term function was achieved using this wrist arthroplasty in a high-demand group of patients with post-traumatic osteoarthritis

We describe the use of a vascularised periosteal patch onlay graft based on the 1,2 intercompartmental supraretinacular artery in the management of 11 patients (ten men, one woman) with chronic nonunion involving the proximal third of the scaphoid. The mean age of the patients was 31 years (21 to 45) with the dominant hand affected in eight. Six of the patients were smokers and three had undergone previous surgery to the scaphoid. All of the proximal fragments were avascular. The presence of union was assessed using longitudinal axis CT. Only three patients progressed to union of the scaphoid and four required a salvage operation for a symptomatic nonunion. The remaining four patients with a persistent nonunion are asymptomatic with low pain scores, good grip strength and a functional range of wrist movement. Although this technique has potential technical advantages over vascularised pedicled bone grafting, the rate of union has been disappointing and we do not recommend it as a method of treatment

We reviewed 13 patients with a complex fracture-dislocation of the proximal interphalangeal joint of a finger and one patient with a complex fracture-dislocation of the interphalangeal joint of thumb. We had treated these injuries using a pins and rubbers traction system which had been modified to avoid friction of the pins against the bone during mobilisation of the joint in order to minimise the risk of osteolysis. A Michigan hand outcome questionnaire was used for subjective assessment. The active range of movement (AROM) of the proximal and distal interphalangeal joints and the grip strength were used for objective assessment. The mean follow-up was 34 months (12 to 49). The mean normalised Michigan hand outcome score was 84. The mean AROM of the proximal interphalangeal joint was 85° and that of the distal interphalangeal joint 48°. The mean grip strength was 92% of the uninvolved hand. Twelve patients have returned to their original occupations. There has been no radiological osteolysis or clinical osteomyelitis. This modified traction system has given acceptable results with a low rate of complications. It is light, cheap, effective and easy to apply

Introduction: The aim of this study is to present the effect of various local anaesthetics, in particular solution concentrations, in peri- and post-operative analgesia in patients with carpal tunnel syndrome (CTS). Material and Method: 105 patients with CTS (81 female, 24 male, ages 27–79) underwent carpal tunnel release under local anaesthesia. The patients were divided into 5 groups (xylocaine 2%, ropivacaine 0.75%, ropivacaine 0.375%, chirocaine 0.5%, chirocaine 0.25%). A tablet of Gabapentin (Neurontin) 400mg was administered to some patients of each group (41 pts of the 105pts) 12 hours prior to surgery. All patients were evaluated immediately after surgery, in 2 weeks and 2 months postoperatively according to VAS pain score, grip strength, finger active motion and two point discrimination. Postoperative complications were also reported. Results: Anesthesia was immediate after the local injection. All patients improved postoperativelly regarding relief from pain and paresthesias. There was no statistically significant difference in grip strength before and after surgery. Only 10 patients used paracetamol immediately after surgery, without any statistically significant correlation to any group of patients. 1 patient developed complex regional pain syndrome 2 months after surgery. Conclusion: The use of local anaesthesia in carpal tunnel release surgery is beneficial in providing immediate intraoperative effect and recovery and mobilization after surgery. Rehabilitation seems to be irrelevant of the type of local anaesthetic that was used during the procedure. Small solution concentrations of local anaesthetics (ropivacaine 0.375%, chirocaine 0.25%) provide adequate analgesia during surgery and provide a normal postoperative course

Objective: The main treatment for unstable distal radius fracture in Québec consists in pinning and cast, with secondary shortening and displacement responsible for lack of motion. The goal of the study is to compare clinical and radiological results after treatment with non-bridging external fixator compared to pinning and cast, with restoration of grip strength as main clinical outcome. Method: Between June 2003 and June 2005, 120 consecutive patients admitted for unstable extra-articular distal radius fracture were randomized in the 2 groups. Early mobilisation was allowed in the group with external fixator, and patients in the other group had pins and cast for 6 weeks. Follow-up was completed after 6 months with determination of clinical and radiological data for the both wrists. 110 patients completed the study, with 2 comparative groups for epidemiologic and radiological criteria (n = 63 for pins and 57 for external fixator). Results: Grip strength was significantly better in the fixator group at 3 months (68,36%;p< 0,001) and 6 months (98,26%;p< 0,001). Active ROM was better and obtained earlier in the fixator group in all directions (p< 0,001). Fixator prevent shortening and secondary displacement in a highly significant way (p< 0,001). No difference in pain medication, but fixator group could begin occupation earlier (p< 0,001). Conclusion: Non-bridging external fixator is a treatment of choice for unstable extra-articular distal radius fractures. The immediate stability allows in all patients (without influence of age, bone quality or fracture displacement) early mobilisation, prevent secondary displacement, and gives earlier and better functional results

The different attributes of the Patient Evaluation Measure (PEM) questionnaire were investigated in 80 patients with a fracture of the scaphoid. Assessments were made at 2, 8, 12, 26 and 52 weeks. Reliability was assessed by measurement of the internal consistency of the different questions in 275 completed PEM forms. Cronbach’s alpha, which needs to lie between 0.7 and 0.9, was 0.9 for the PEM. Pain, tenderness, swelling, wrist movement and grip strength correlated with the PEM score confirming the validity of the assessment. Changes in the different variables between visits correlated significantly with changes in the PEM score; its effect size and standardised response mean were comparable to those of grip strength and movement, confirming the responsiveness of this questionnaire. Gender, dominance and the side injured did not influence the scores. Older patients had a poorer outcome as assessed by the score which appeared to be a true effect and not age bias. Our study confirmed that the PEM is a reliable, valid and responsive instrument in assessing outcomes of disorders of the hand

A vascular necrosis of the lunate, first described by Kienböck, can be treated either conservatively or by various surgical procedures. We compared the results of 18 conservatively treated patients, all of whom had stage-2 or stage-3 disease, with those of 15 who underwent a radial shortening procedure. We evaluated pain, range of movement, grip strength and functional disability, and determined the progression of the disease by assessing radiologically carpal height, the width and flattening of the lunate, the radioscaphoid angle, the pattern of the fracture and sclerosis and cysts. The mean follow-up was for 3.6 years (1.5 to 9). Patients treated by radial shortening had less pain and better grip strength than those managed conservatively. In some patients with stage-3 disease treated conservatively there was rapid deterioration to carpal collapse. Although radial shortening did not reverse or prevent carpal collapse, it slowed down the process in patients with stage-3 disease. We recommend a radial shortening procedure for patients with severe pain and radiological signs of progressive carpal collapse

A total of 179 adult patients with displaced intra-articular fractures of the distal radius was randomised to receive indirect percutaneous reduction and external fixation (n = 88) or open reduction and internal fixation (n = 91). Patients were followed up for two years. During the first year the upper limb musculoskeletal function assessment score, the SF-36 bodily pain sub-scale score, the overall Jebsen score, pinch strength and grip strength improved significantly in all patients. There was no statistically significant difference in the radiological restoration of anatomical features or the range of movement between the groups. During the period of two years, patients who underwent indirect reduction and percutaneous fixation had a more rapid return of function and a better functional outcome than those who underwent open reduction and internal fixation, provided that the intra-articular step and gap deformity were minimised

Introduction. Unstable dorsal fracture/dislocation of PIP joint is a complex injury and difficult to treat. Different treatment methods have been described with varying results. We describe a novel technique to combine fracture fixation with volar plate repair using micro anchor suture. Material and methods. Between July and December 2005, 11 consecutive patients with unstable dorsal PIP joint dislocations underwent open reduction and volar plate repair using our technique. Nine patients had dorsal fracture dislocations and two had open dislocations. All patients were males and their average age was 26 years. All patients were reviewed with the minimum follow up of 12 months. The pain score, range of movements and grip strength were recorded and compared to the normal side. Operative Technique. Volar approach was made using a semi Brunar incision. One or two micro bioabsorbable anchors (Mitek, Ethicon Ltd, UK) were used to stabilise the joint and repair the volar plate. Additional anchor was used to repair the collateral ligament when indicated. Post-operatively the hand was rested in Edinburgh functional splint for 10 days followed by active and assisted range of movements under hand physiotherapist supervision. Results. 10 out 11 patients had excellent pain relief. The average range of movement of the PIP joint was 100 degrees. One patient with neglected PIP joint fracture dislocation for 10 weeks had mild residual pain and stiffness. The mean grip strength was 87% of that of contralateral normal side. All patients returned to their same work as before. 8 out of 9 patients returned to play their regular sports at the same level. All patients were satisfied with the functional outcome. Conclusion. Combined fracture fixation and volar plate repair through anterior approach using micro bioabsorbable anchors appears to be very effective way of treating this otherwise complex unstable fracture/dislocation of PIP joint

Introduction. Several clinical and radiological studies have confirmed the benefits of using Volar Locking Plates (VLPs) to treat unstable distal radius fractures. The “theoretical” advantage of VLPs compared to standard plate fixation is that VLPs, through their design, intrinsically provide angular stability for most fracture configurations including comminuted fractures and, quite possibly, osteoporotic fractures. However few studies have compared the clinical results of patients of different ages who have been treated using VLPs. Aim. The aim of this study was to compare the clinical outcomes of VLP fixation of displaced distal radius in younger (<59 yrs) and older (>60yrs) patients. Patients & Methods. We reviewed 78 consecutive patients who had undergone ORIF of their displaced distal radial fractures using a VLP. All patients were reviewed at predetermined time points by an independent observer and the findings at 6 months are presented. In addition to documenting the standard demographics for each patient and classifying the fractures using the OTA/AO system, wrist function was assessed using Range of Movement (ROM), Grip strength (GS), the Modified Gartland & Werley score (MGWS), the Patient Rated Wrist Evaluation (PRWE), the Quick DASH scores, and overall scores of wrist Pain and Function using Visual Analogue Scores (VAS). Results. 43 patients were under 60 years of age and 35 patients were 60 years or over. The proportion of extra-articular to intra-articular fractures were similar for both age groups. There was little difference in terms of patient perception of Pain and Function, or ROM, MGWS (7.2 versus 6.9), PRWE (24 versus 23.6) and quick DASH scores (17.3 versus 19.1) between the two groups at 6 months. The younger group did have significantly better grip strength, but when compared as a percentage of the uninjured wrist, the results were also similar (83% vs 80%). Conclusions. VLPs are a suitable option for fixing distal radial fractures in older patients (>60yrs) and the clinical results appear to be just as good as they are in younger patients
