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

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

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. 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

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

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

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
