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

Aims. Chronic conditions of the wrist may be difficult to manage because pain and psychiatric conditions are correlated with abnormal function of the hand. Additionally, intra-articular inflammatory cytokines may cause pain. We aimed to validate the measurement of inflammatory cytokines in these conditions and identify features associated with symptoms. Patients and Methods. The study included 38 patients (18 men, 20 women, mean age 43 years) with a chronic condition of the wrist who underwent arthroscopy. Before surgery, the Self-Rating Depression Scale (SDS), Hand20 questionnaire and a visual analogue scale (VAS) for pain were used. Cytokine and chemokine levels in the synovial fluid of the wrist were measured using enzyme-linked immunosorbent assays and correlations between the levels with pain were analysed. Gene expression profiles of the synovial membranes were assessed using quantitative polymerase chain reaction. Results. Older patients had high pre-operative Hand20 scores. One-year post-operative Hand20 and VAS scores and pre-operative VAS scores correlated with SDS scores. Post-operative VAS scores negatively correlated with the expression of nerve growth factor and SDS scores positively correlated with the expression of tumour necrosis factor-alpha and negatively correlated with the expression of tumour necrosis factor-converting enzyme. Conclusion. There was a positive correlation between depression and chronic conditions of the wrist. Levels of some cytokines correlate with pain and depression. Additionally, cytokines may be important in the assessment and treatment of chronic conditions of the wrist and depression. Cite this article: Bone Joint J 2016;98-B:961–8

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 investigated the clinical response to arthroscopic synovectomy in patients with undifferentiated chronic monoarthritis (UCMA) of the wrist. Arthroscopic synovectomy was performed on 20 wrists in 20 patients with UCMA of the wrist who had not responded to non-steroidal anti-inflammatory drugs. The mean duration of symptoms at the time of surgery was 4.3 months (3 to 7) and the mean follow-up was 51.8 months (24 to 94). Inflamed synovium was completely removed from the radiocarpal, midcarpal and distal radioulnar joints using more portals than normal. After surgery, nine patients had early remission of synovitis and 11 with uncontrolled synovitis received antirheumatic medication. Overall, there was significant improvement in terms of pain relief, range of movement and Mayo score. Radiological deterioration was seen in five patients who were diagnosed as having rheumatoid arthritis during the follow-up period. Lymphoid follicles and severe lymphocyte infiltration were seen more often in synovial biopsies from patients with uncontrolled synovitis. These results suggest that arthroscopic synovectomy provides pain relief and functional improvement, and allows rapid resolution of synovitis in about half of patients with UCMA of the wrist

Aims. To analyze the short-term outcome of two types of total wrist arthroplasty (TWA) in terms of wrist function, migration, and periprosthetic bone behaviour. Methods. A total of 40 patients suffering from non-rheumatoid wrist arthritis were enrolled in a randomized controlled trial comparing the ReMotion and Motec TWAs. Patient-rated and functional outcomes, radiological changes, blood metal ion levels, migration measured by model-based radiostereometric analysis (RSA), bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA), complications, loosening, and revision rates at two years were compared. Results. Patient-Rated Wrist and Hand Evaluation (PRWHE) scores, abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) scores, and pain improved similarly and significantly in both groups. Wrist motion improved significantly in the Motec group only, and forearm rotation in the ReMotion group only. Cobalt (Co) and chromium (Cr) blood ion levels were significantly higher in the metal-on-metal (MoM) Motec group than in the metal-on-polyethylene (MoP) ReMotion group. Mean total translation was 0.65 mm (95% confidence interval (CI) 0.26 to 1.12) and 0.27 mm (95% CI 0.14 to 0.47) for the ReMotion carpal and radial components, and 0.32 mm (95% CI 0.22 to 0.45) and 0.26 mm (95% CI 0.20 to 0.34) for the Motec metacarpal and radial components, respectively. Apart from dorsal and volar tilts, which were significantly higher for the radial ReMotion than for the Motec component, no significant differences in absolute migration occurred. BMD around the radial components never returned to baseline. Almost one-third of patients required reoperation due to complications. Two ReMotion implants were revised to Motec TWAs due to carpal component loosening, and three Motec MoM articulations were revised to metal-on-polyether ether ketone due to painful synovitis. Conclusion. Both implants provided matched function and were stable at short-term follow-up, but with a high complication rate. This procedure should be restricted to specialist centres undertaking prospective analysis until its role is clarified. Cite this article: Bone Joint J 2022;104-B(10):1132–1141

The wrist is a complex joint involving many small bones and complicated kinematics. It has, therefore, been traditionally difficult to image and ascertain information about kinematics when making a diagnosis. Although MRI and fluoroscopy have been used, they both have limitations. Recently, there has been interest in the use of 4D-CT in imaging the wrist. This review examines the literature regarding the use of 4D-CT in imaging the wrist to assess kinematics and its ability to diagnose pathology. Some questions remain about the description of normal ranges, the most appropriate method of measuring intercarpal stability, the accuracy compared with established standards, and the place of 4D-CT in postoperative assessment.

Arthritis of the wrist is a painful disabling condition that has various causes and presentations. The traditional treatment has been a total wrist fusion at a price of the elimination of movement. However, forms of treatment which allow the preservation of movement are now preferred. Modern arthroplasties of the wrist are still not sufficiently robust to meet the demands of many patients, nor do they restore normal kinematics of the wrist. A preferable compromise may be selective excision and partial fusion of the wrist using knowledge of the aetiology and pattern of degenerative change to identify which joints can be sacrificed and which can be preserved. . This article provides an overview of the treatment options available for patients with arthritis of the wrist and an algorithm for selecting an appropriate surgical strategy.

Wrist block has been used to provide pain relief for many procedures on the hand and wrist but its role in arthroscopy of the wrist remains unexplored. Chondrotoxicity has been a concern with the intra-articular infiltration of local anaesthetic. We aimed to evaluate and compare the analgesic effect of portal and wrist joint infiltration with a wrist block on the pain experienced by patients after arthroscopy of the wrist. A prospective, randomised, double-blind trial was designed and patients undergoing arthroscopy of the wrist under general anaesthesia as a day case were recruited for the study. Levo-bupivacaine was used for both techniques. The effects were evaluated using a ten-point visual analogue scale, and the use of analgesic agents was also compared. The primary outcomes for statistical analyses were the mean pain scores and the use of analgesia post-operatively. . A total of 34 patients (63% females) were recruited to the portal and joint infiltration group and 32 patients (59% males) to the wrist block group. Mean age was 40.8 years in the first group and 39.7 years in the second group (p > 0.05). Both techniques provided effective pain relief in the first hour and 24 hours post-operatively but wrist block gave better pain scores at bedtime on the day of surgery (p = 0.007) and at 24 hours post-operatively (p = 0.006). . Wrist block provides better and more reliable analgesia in patients undergoing arthroscopy of the wrist without exposing patients to the risk of chondrotoxicity.

We retrospectively compared wrist arthrodesis using the Mannerfelt technique in 19 or an AO-plate in 23 patients with long-standing rheumatoid arthritis. The mean follow-up was for 76 months. Compared with the Mannerfelt fusion group, patients in the AO-plate group reported greater satisfaction with their wrist function (74% vs 37%, p = 0.015). Complications were reported in six wrists in the AO-plate group and two wrists in the Mannerfelt fusion group (p = 0.258). At final follow-up, 95% of patients (41) reported either no pain or only mild pain. There was improvement in flexion of the finger joints in both groups but no significant improvement in the extension lag in either group. Both methods relieve pain and improve function. Overall, the activities of daily living scores and the patients’ subjective assessment of outcome tended to be higher in the AO-plate group than in the Mannerfelt fusion group, although the difference was not statistically significant. Similarly, although more postoperative complications occurred in the AO-plate group, the difference between the two groups was not statistically significant

Aims. A conventional arthroscopic capsuloligamentous repair is a reliable surgical solution in most patients with scapholunate instability. However, this repair does not seem to be sufficient for more advanced injuries. The aim of this study was to evaluate the functional results of a wide arthroscopic dorsal capsuloligamentous repair (WADCLR) in the management of severe scapholunate instability. Methods. This was a prospective single-centre study undertaken between March 2019 and May 2021. The primary outcome was the evaluation of the reduction of the radiological deformity and the functional outcomes after WADCLR. A secondary outcome was the evaluation of the effectiveness of this technique in patients with the most severe instability (European Wrist Arthroscopy Society (EWAS) stage 5). The patients were reviewed postoperatively at three, six, and 12 months. Results. The study included 112 patients (70 male and 42 female). Their mean age was 31.6 years (16 to 55). A total of three patients had EWAS stage 3A injuries, 12 had stage 3B injuries, 29 had stage 3C injuries, 56 had stage 4 injuries, and 12 had stage 5 injuries. There was a significant improvement of the radiological signs in all patients with a return to normal values. There was also a significant improvement in all aspects of function except for flexion, in which the mean increase was negligible (0.18° on average). There was also a significant improvement in all criteria for patients with a stage 5 injury, except for some limitation of extension, flexion, and radial and ulnar deviation, although these showed a trend towards improvement (except for flexion). Conclusion. WADCLR is a minimally invasive, easy, and reproducible technique with few complications, offering a clear improvement in function and a reduction in the radiological deformity at one year postoperatively.

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. 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.

The purposes of this study were to define the range of laxity of the interosseous ligaments in cadaveric wrists and to determine whether this correlated with age, the morphology of the lunate, the scapholunate (SL) gap or the SL angle. We evaluated 83 fresh-frozen cadaveric wrists and recorded the SL gap and SL angle. Standard arthroscopy of the wrist was then performed and the grades of laxity of the scapholunate interosseous ligament (SLIL) and the lunotriquetral interosseous ligament (LTIL) and the morphology of the lunate were recorded. Arthroscopic evaluation of the SLIL revealed four (5%) grade I specimens, 28 (34%) grade II, 40 (48%) grade III and 11 (13%) grade IV. Evaluation of the LTIL showed 17 (20%) grade I specimens, 40 (48%) grade II, 28 (30%) grade III and one (1%) grade IV. On both bivariate and multivariate analysis, the grade of both the SLIL and LTIL increased with age, but decreased with female gender. The grades of SLIL or LTIL did not correlate with the morphology of the lunate, the SL gap or the SL angle. The physiological range of laxity at the SL and lunotriquetral joints is wider than originally described. The intercarpal ligaments demonstrate an age-related progression of laxity of the SL and lunotriquetral joints. There is no correlation between the grades of laxity of the SLIL or LTIL and the morphology of the lunate, the SL gap or the SL grade. Based on our results, we believe that the Geissler classification has a role in describing intercarpal laxity, but if used alone it cannot adequately diagnose pathological instability. We suggest a modified classification with a mechanism that may distinguish physiological laxity from pathological instability

Aims. There is no level I evidence dealing with the optimal period of immobilization for patients with a displaced distal radial fracture following closed reduction. A shorter period might lead to a better functional outcome due to less stiffness and pain. The aim of this study was to investigate whether this period could be safely reduced from six to four weeks. Methods. This multicentre randomized controlled trial (RCT) included adult patients with a displaced distal radial fracture, who were randomized to be treated with immobilization in a cast for four or six weeks following closed reduction. The primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) score after follow-up at one year. Secondary outcomes were the abbreviated version of the Disability of Arm, Shoulder and Hand (QuickDASH) score after one year, the functional outcome at six weeks, 12 weeks, and six months, range of motion (ROM), the level of pain after removal of the cast, and complications. Results. A total of 100 patients (15 male, 85 female) were randomized, with 49 being treated with four weeks of immobilization in a cast. A total of 93 completed follow-up. The mean PRWE score after one year was 6.9 (SD 8.3) in the four-week group compared with 11.6 (SD 14.3) in the six-week group. However, this difference of -4.7 (95% confidence interval -9.29 to 0.14) was not clinically relevant as the minimal clinically important difference of 11.5 was not reached. There was no significant difference in the ROM, radiological outcome, level of pain, or complications. Conclusion. In adult patients with a displaced and adequately reduced distal radial fracture, immobilization in a cast for four weeks is safe, and the results are similar to those after a period of immobilization of six weeks.

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

Aims. There is a lack of published evidence relating to the rate of nonunion seen in occult scaphoid fractures, diagnosed only after MRI. This study reports the rate of delayed union and nonunion in a cohort of patients with MRI-detected acute scaphoid fractures. Methods. This multicentre cohort study at eight centres in the UK included all patients with an acute scaphoid fracture diagnosed on MRI having presented acutely following wrist trauma with normal radiographs. Data were gathered retrospectively for a minimum of 12 months at each centre. The primary outcome measures were the rate of acute surgery, delayed union, and nonunion. Results. A total of 1,989 patients underwent acute MRI for a suspected scaphoid fracture during the study period, of which 256 patients (12.9%) were diagnosed with a previously occult scaphoid fracture. Of the patients with scaphoid fractures, six underwent early surgical fixation (2.3%) and there was a total of 16 cases of delayed or nonunion (6.3%) in the remaining 250 patients treated with cast immobilization. Of the nine nonunions (3.5%), seven underwent surgery (2.7%), one opted for non-surgical treatment, and one failed to attend follow-up. Of the seven delayed unions (2.7%), one (0.4%) was treated with surgery at two months, one (0.4%) did not attend further follow-up, and the remaining five fractures (1.9%) healed after further cast immobilization. All fractures treated with surgery had united at follow-up. There was one complication of surgery (prominent screw requiring removal). Conclusion. MRI-detected scaphoid fractures are not universally benign, with delayed or nonunion of scaphoid fractures diagnosed only after MRI seen in over 6% despite appropriate initial immobilization, with most of these patients with nonunion requiring surgery to achieve union. This study adds weight to the evidence base supporting the use of early MRI for these patients. Cite this article: Bone Joint J 2024;106-B(4):387–393

Disorders of the pisotriquetral joint are well recognised as the cause of pain on the ulnar side of the wrist. The joint is not usually examined during routine arthroscopy because it is assumed to have a separate joint cavity to the radiocarpal joint, although there is often a connection between the two. We explored this connection during arthroscopy and in fresh-frozen cadaver wrists and found that in about half of the cases the pisotriquetral joint could be visualised through standard wrist portals. Four different types of connection were observed between the radiocarpal joint and the pisotriquetral joint. They ranged from a complete membrane separating the two, to no membrane at all, with various other types of connection in between. We recommend that inspection of the pisotriquetral joint should be a part of the protocol for routine arthroscopy of the wrist

Aims. It is not clear which type of casting provides the best initial treatment in adults with a distal radial fracture. Given that between 32% and 64% of adequately reduced fractures redisplace during immobilization in a cast, preventing redisplacement and a disabling malunion or secondary surgery is an aim of treatment. In this study, we investigated whether circumferential casting leads to fewer fracture redisplacements and better one-year outcomes compared to plaster splinting. Methods. In a pragmatic, open-label, multicentre, two-period cluster-randomized superiority trial, we compared these two types of casting. Recruitment took place in ten hospitals. Eligible patients aged ≥ 18 years with a displaced distal radial fracture, which was acceptably aligned after closed reduction, were included. The primary outcome measure was the rate of redisplacement within five weeks of immobilization. Secondary outcomes were the rate of complaints relating to the cast, clinical outcomes at three months, patient-reported outcome measures (PROMs) (using the numerical rating scale (NRS), the abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Patient-Rated Wrist/Hand Evaluation (PRWHE) scores), and adverse events such as the development of compartment syndrome during one year of follow-up. We used multivariable mixed-effects logistic regression for the analysis of the primary outcome measure. Results. The study included 420 patients. There was no significant difference between the rate of redisplacement of the fracture between the groups: 47% (n = 88) for those treated with a plaster splint and 49% (n = 90) for those treated with a circumferential cast (odds ratio 1.05 (95% confidence interval (CI) 0.65 to 1.70); p = 0.854). Patients treated in a plaster splint reported significantly more pain than those treated with a circumferential cast, during the first week of treatment (estimated mean NRS 4.7 (95% CI 4.3 to 5.1) vs 4.1 (95% CI 3.7 to 4.4); p = 0.014). The rate of complaints relating to the cast, clinical outcomes and PROMs did not differ significantly between the groups (p > 0.05). Compartment syndrome did not occur. Conclusion. Circumferential casting did not result in a significantly different rate of redisplacement of the fracture compared with the use of a plaster splint. There were comparable outcomes in both groups.

We have measured the three-dimensional patterns of carpal deformity in 20 wrists in 20 rheumatoid patients in which the carpal bones were shifted ulnarwards on plain radiography. Three-dimensional bone models of the carpus and radius were created by computerised tomography with the wrist in the neutral position. The location of the centroids and rotational angle of each carpal bone relative to the radius were calculated and compared with those of ten normal wrists. In the radiocarpal joint, the proximal row was flexed and the centroids of all carpal bones translocated in an ulnar, proximal and volar direction with loss of congruity. In the midcarpal joint, the distal row was extended and congruity generally well preserved. These findings may facilitate more positive use of radiocarpal fusion alone for the deformed rheumatoid wrist

Aims. The aim of this study was to analyze the association between the shape of the distal radius sigmoid notch and triangular fibrocartilage complex (TFCC) foveal tear. Methods. Between 2013 and 2018, patients were retrospectively recruited in two different groups. The patient group comprised individuals who underwent arthroscopic transosseous TFCC foveal repair for foveal tear of the wrist. The control group comprised individuals presenting with various diseases around wrist not affecting the TFCC. The study recruited 176 patients (58 patients, 118 controls). The sigmoid notch shape was classified into four types (flat-face, C-, S-, and ski-slope types) and three radiological parameters related to the sigmoid notch (namely, the radius curvature, depth, and version angle) were measured. The association of radiological parameters and sigmoid notch types with the TFCC foveal tear was investigated in univariate and multivariate analyses. Receiver operating characteristic curves were used to estimate a cut-off for any statistically significant variables. Results. Univariate analysis showed that the flat-face type was more prevalent in the patients than in the control group (43% vs 21%; p = 0.002), while the C-type was lower in the patients than in the control group (3% vs 17%; p = 0.011). The depth and version angle of sigmoid notch showed a negative association with the TFCC foveal tear in the multivariate analysis (depth: odds ratio (OR) 0.380; p = 0.037; version angle: OR 0.896; p = 0.033). Estimated cut-off values were 1.34 mm for the depth (area under the curve (AUC) = 0.725) and 10.45° for the version angle (AUC = 0.726). Conclusion. The proportion of flat-face sigmoid notch type was greater in the patient group than in the control group. The depth and version angle of sigmoid notch were negatively associated with TFCC foveal injury. Cite this article: Bone Joint J 2020;102-B(6):749–754

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

Aims. Total wrist arthrodesis (TWA) produces a spectrum of outcomes. We investigated this by reviewing 77 consecutive TWA performed for inflammatory and post-traumatic arthropathies, wrist instability and as a salvage procedure. . Patients and Methods. All operations were performed by a single surgeon using a specifically designed pre-contoured dorsally applied non-locking wrist arthrodesis plate at a single centre. . Results. Median post-operative Buck-Gramcko Lohman (BGL), Disabilities of the Arm, Shoulder and Hand and Patient Rated Wrist Evaluation scores at six years (interquartile range (IQR) 3 to 11) were 9 (IQR = 6 to 10), 19 (IQR = 7 to 45) and 13 (IQR = 1 to 31) respectively. Polyarticular inflammatory arthritis and female gender were associated with poorer patient-reported outcomes, although the effect of gender was partly explained by higher rates of inflammatory disease among women. Return to work was negatively influenced by workers’ compensation and non-inflammatory wrist pathology. There was no difference in complication rates for inflammatory and non-inflammatory indications. . Take home message: Polyarticular inflammatory arthritis is a risk factor for adverse patient-reported outcomes in TWA. Furthermore, when compared with patients without inflammatory arthritis, dorsally applied pre-contoured plates can be used for wrist arthrodesis in patients with inflammatory arthritis without an increased risk of complications.

1. A simple and effective method of wrist arthrodesis is described. Originally designed for the correction of flexion deformity of the wrist, it is useful also as a routine method of wrist fusion. 2. The results in nineteen cases are reviewed

Three palmar wrist ligaments from fresh human cadavers were dissected from the proximal to the distal insertions and stained to identify the mechanoreceptors. Golgi organs, Pacinian corpuscles, Ruffini endings and free nerve endings were present in all three ligaments. In the radial collateral and radiolunate ligaments they were found in increased density towards the proximal and distal insertions. A more uniform distribution was found in the radioscaphocapitate ligament which has attachments to three bones. The palmar wrist ligaments may have a significant sensory role in maintaining the stability of the wrist and in controlling its movement. Although technically difficult, the surgical repair of traumatic wrist defects should attempt to preserve the innervation of the ligaments, shown to be mainly near bony attachments. This may allow improvement in postoperative outcomes by preserving some proprioception. In some painful post-traumatic or degenerative conditions, however, denervation may be advantageous

We have implanted 76 biaxial total wrist prostheses as a primary procedure in patients with rheumatoid arthritis of the wrist. A total of 66 was reviewed at a mean follow-up time of 52 months. Pain was relieved in 67% of the surviving wrist replacements. On the basis of the Hospital for Special Surgery scoring system, 49 wrists (74%) were graded as fair to excellent. More than half of the 27 patients who had an arthrodesis on the contralateral wrist would have preferred a second arthroplasty. Five replacements were revised or fused because of loosening and a further nine showed signs of radiological loosening, three of which were asymptomatic. The probability of survival of the biaxial total wrist replacement at eight years was 83% with revision surgery as the terminal event, 78% with radiological loosening as the endpoint and 82% with dorsal migration and displacement from the metacarpal as the terminal event. There was a linear relationship between subsidence of the component and distal loosening. There was no evidence that the length of the stem of the carpal component, within the third metacarpal, affected any of the terminal events. The position and alignment of the carpal component within the bone at the time of surgery significantly affect the outcome and can be used to predict failure

A study has been made of fifty-six patients suffering from rheumatoid arthritis in whom sixty-nine wrists were fused. The purpose of the investigation was to evaluate to what extent the position of the fused wrist influenced the position of the fingers in the frontal plane. All sixty-nine wrists were followed up by radiographic examination controls, and thirty-seven of the wrists were also examined clinically. The mean period of observation after operation was seven years and ten months. The findings support the so-called "zigzag" theory based on the concept of carpus-metacarpus acting as Landsmeer's intercalated bone in a bi-articular system. When the wrists were fused in more than 5 degrees of radial deviation seventeen of twenty hands showed ulnar drift of the fingers on radiographic examination. Of the nine patients in this group examined clinically, all showed ulnar drift. A strong tendency to correction of the finger position is seen when the hands are pressed against the cassette. For this reason the clinical examination, during which the finger deviation was examined with the metacarpo-phalangeal joints in 30 degrees of flexion regularly revealed an ulnar deviation of 5 degrees more than that shown by radiographic examination. In eighteen wrists the fusion had been done in more than 5 degrees of ulnar deviation. Fourteen of these hands showed a resulting radial deviation of the fingers on radiographic examination. In a group of thirty-one wrists fused in neutral position (0 degrees±5 degrees) only six hands showed more than 5 degrees of finger deviation to either side. The condition of the metacarpo-phalangeal joints asjudged from radiographs did not seem to influence the deviation of the fingers either in direction or in degree. The direction of the deviation of the fingers was almost regularly the opposite to that of the fused wrist. Five hands showing no visible pathological changes in the metacarpo-phalangeal joints displayed finger drift

Simple decompression of the extensor tendons at the wrist was carried out on fifty-four wrists in a total of forty-one patients with rheumatoid disease. This procedure was combined with excision of the ulnar head in forty-five wrists. Complete resolution of the synovitis occurred in 81.5 per cent of the wrists. In two patients the tendons ruptured soon after operation and in both cases this was due to prolapse of the ulnar stump after an associated Darrach procedure. The clinical results of decompression compare favourably with those of the widely accepted operation of dorsal tenosynovectomy

Aims. The aims of this study were: firstly, to investigate the influence of the thickness of cartilage at the sigmoid notch on the inclination of the distal radioulnar joint (DRUJ), and secondly, to compare the sensitivity and specificity of MRI with plain radiographs for the assessment of the inclination of the articular surface of the DRUJ in the coronal plane. . Patients and Methods. Contemporaneous MRI images and radiographs of 100 wrists from 98 asymptomatic patients (mean age 43 years, (16 to 67); 52 male, 53%) with no history of a fracture involving the wrist or surgery to the wrist, were reviewed. The thickness of the cartilage at the sigmoid notch, inclination of the DRUJ and Tolat Type of each DRUJ were determined. . Results. The assessment using MRI scans and cortical bone correlated well with radiographs, with a kappa value of 0.83. The mean difference between the inclination using the cortex and cartilage on MRI scans was 12°, leading to a change of Tolat type of inclination in 66% of wrists. No reverse oblique (Type 3) inclinations were found when using the cartilage to assess inclination. . Conclusion . These data revealed that when measuring the inclination of the DRUJ using cartilage, reverse oblique inclinations might not exist. The data suggest that performing an ulna shortening osteotomy might be reasonable even in distal radioulnar joints where the plain radiographic appearance suggests an unfavourable reverse oblique inclination in the coronal plane. We recommend using MRI to validate radiographs in those that appear to be reverse oblique (Tolat Type 3), as the true inclination might be different, thereby removing one possible contraindication to ulnar shortening.

We describe a technique for arthroscopy of the wrist which is carried out without traction and with the arm lying horizontally on the operating table. The wrist is not immobilised, which makes it possible to assess the extent of instability after a ligamentous tear. In a prospective study of 30 patients we compared this technique with conventional wrist arthroscopy, performing the new method first followed by conventional arthroscopy. The advantages are that the horizontal position of the arm allows the surgeon to proceed directly from arthroscopic diagnosis to treatment, and that no change of position is required for fluoroscopy. In terms of diagnostic sensitivity, we found our technique matched that of conventional arthroscopy. We had no difficulty in carrying out minor surgical procedures such as debridement and suturing

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.

We enrolled 34 normal volunteers to test the hypothesis that there were two types of movement of the wrist. On lateral radiographs two distinct patterns of movement emerged. Some volunteers showed extensive rotation of the lunate with a mean range of dorsiflexion of 65°, while others had a mean range of 50°. The extensive rotators were associated with a greater excursion of the centre of articulation of the wrist. It is suggested that dynamic external fixation of a fracture of the distal radius carries with it the risk of stretching the ligaments or causing volar displacement at the site of the fracture

In a prospective study, 204 consecutive patients with displaced Colles' fractures had closed reduction then plaster immobilisation. Three different positions of the wrist in plaster were randomly allocated: palmar flexion, neutral and dorsiflexion. The results in the three groups were compared. Fractures immobilised with the wrist in dorsiflexion showed the lowest incidence of redisplacement, especially of dorsal tilt, and had the best early functional results. Immobilisation of the wrist in palmar flexion has a detrimental effect on hand function; it is suggested that it is also one of the main causes for redisplacement of the fracture. This is discussed in relation to the functional anatomy of the wrist and the mechanics of plaster fixation

Although the outcome of fractures of the distal radius is traditionally assessed using objective clinical variables such as grip strength and range of movement of the wrist, the extent to which they reflect function and outcomes of importance for the patient is uncertain. This may cause considerable inconsistencies in the assessment of outcome using current scoring systems. We prospectively studied 31 patients recovering from unstable fractures of the distal radius in order to investigate the association between objective variables and the level of post-traumatic disability of the wrist as measured by the patient-rated wrist evaluation (PRWE) score. Multiple regression showed considerable differences in the extent to which limitations in specific objective clinical variables reflected the level of disability of the wrist. Grip strength was shown to be a significant predictor of the PRWE score (regression coefficient −1.09, 95% confidence interval −1.76 to −0.42, p < 0.01) and thus appears to be a sensitive indicator of return of function of the wrist. Forearm rotation and flexion and extension of the wrist were not significantly associated with the PRWE score. These observations should be taken into account during the evaluation of methods of treatment and in constructing future clinical outcome scoring systems

Twenty-six index patients with primary Madelung's deformity of the wrist were examined, as were sixty-five of their relatives. Standard radiographs were taken and measured to determine whether mesomelic dwarfism, a feature of dyschondrosteosis, was present. No case of mesomelia was found. No evidence of Madelung's deformity was found in the relatives of the index patients, who were all female. It is concluded that primary Madelung's deformity of the wrist is not an expressions of dyschondrosteosis, that it is not inherited, and that it does not occur in the male. One index patient with dyschondrosteosis was examined. Eight of her relatives were similarly affected, and three of these were male. It is suggested that previously recorded male cases of Madelung's deformity of the wrist were expressions of dyschondrosteosis or of secondary deformity

Arthrodesis of the wrist is a standard operation which is indicated for severe rheumatoid arthritis in which destruction is too advanced for more conservative procedures, or after failure of previous surgery. We have developed an L-shaped plate designed for this purpose. It provides rigid internal fixation with the wrist in the neutral position and utilises bone grafts obtained from the distal ulna and the carpal bones. We have carried out 29 successful fusions between 1992 and 1995. In all 29 patients synovectomy and resection of the head of the ulna were performed; 11 also had reconstruction of ruptured extensor tendons. All the patients obtained bony union, pain relief and improved function

We performed a neurological and radiological study of the wrists of 58 patients with Hansen’s disease and 60 age-matched healthy control subjects. Significant differences (p < 0.01) were found between the groups in the carpal glenoid sector, the radial physeal widening index, the carpal ulnar distance, the carpal index and in distal radio-ulnar discrepancy. Comparison of the results in three subgroups of leprous patients with sensory impairment (group A-1), motor deficit (A-2) and no neurological impairment (A-3), showed significant differences (p < 0.01) between group A-1 and the other two. This suggests that in these patients the changes in the carpus and radiocarpal joint may be caused by neuropathic arthropathy of the wrist. Our findings are of particular interest since there are few reports of neuropathic arthropathy in non-weight-bearing joints

We performed 45 wrist arthrodeses in 43 patients by a modification of the AO technique using the dynamic compression plate. Radiological follow-up was obtained in 41 wrists; all had united at a mean of ten weeks. Clinical follow-up was obtained in 32 wrists. Subjectively, the surgical outcome was satisfactory in 26, marginally satisfactory in two and unsatisfactory in four. This method is safe and reliable. The plate can be contoured to allow a variety of positions of fusion, and gives rigid immobilisation. The rate of union is higher than that for other techniques

1 . A specific mechanism of injury can produce a tear of the articular disc of the wrist without any associated bony lesion. 2. Torn discs have been found associated with Colles's fractures and with dislocation of the inferior radio-ulnar joint. 3. The injury gives rise to clear-cut symptoms and definite physical signs. 4. Operation in fourteen cases has shown five types of tear of the disc. 5. Arthrographs of the wrist are helpful in establishing the diagnosis. 6. In isolated tears removal ofthe disc relieves the symptoms and does not prejudice function. 7. If there is other joint injury, removal of the disc cannot be expected to give as satisfactory a result

We analysed the results of arthroscopic synovectomy of the wrist in 18 patients (19 wrists) with rheumatoid arthritis who had not responded to conservative treatment. The patients’ symptoms were assessed using visual analogue scales for pain and satisfaction. Standard posteroanterior radiographs which were taken pre-operatively and at final follow-up were analysed using a modified Larsen scoring system (normal, 0; total destruction, 40). The mean follow-up period was 29.2 months (24 to 45). The mean pre-operative pain score was 8.58 which decreased to 3.58 one year after surgery and increased again to 4.42 at final follow-up. This suggested a gradual increase in pain with time. The mean satisfaction score was 6.26. The mean modified Larsen’s score was 9.8 pre-operatively and 13.9 at final follow-up, which demonstrated the slow progression of degenerative changes. Arthroscopic synovectomy for rheumatoid arthritis of the wrist allows effective pain relief and high patient satisfaction, although any prolonged benefits will require long-term follow-up

Fractures of the odontoid peg are common spinal injuries in the elderly. This study compares the survivorship of a cohort of elderly patients with an isolated fracture of the odontoid peg versus that of patients who have sustained a fracture of the hip or wrist. A six-year retrospective analysis was performed on all patients aged > 65 years who were admitted to our spinal unit with an isolated fracture of the odontoid peg. A Kaplan–Meier table was used to analyse survivorship from the date of fracture, which was compared with the survivorship of similar age-matched cohorts of 702 consecutive patients with a fracture of the hip and 221 consecutive patients with a fracture of the wrist. A total of 32 patients with an isolated odontoid fracture were identified. The rate of mortality was 37.5% (n = 12) at one year. The period of greatest mortality was within the first 12 weeks. Time made a lesser contribution from then to one year, and there was no impact of time on the rate of mortality thereafter. The rate of mortality at one year was 41.2% for male patients (7 of 17) compared with 33.3% for females (5 of 15). . The rate of mortality at one year was 32% (225 of 702) for patients with a fracture of the hip and 4% (9 of 221) for those with a fracture of the wrist. There was no statistically significant difference in the rate of mortality following a hip fracture and an odontoid peg fracture (p = 0.95). However, the survivorship of the wrist fracture group was much better than that of the odontoid peg fracture group (p < 0.001). Thus, a fracture of the odontoid peg in the elderly is not a benign injury and is associated with a high rate of mortality, especially in the first three months after the injury.

We have examined whether the rotatory subluxation of the scaphoid which is seen in patients with advanced Kienböck’s disease is associated with scapholunate advanced collapse (SLAC) wrist. We studied 16 patients (11 men, 5 women) who had stage-IV Kienböck’s disease with chronic subluxation of the scaphoid. All had received conservative treatment. The mean period of affection with Kienböck’s disease was 30 years (14 to 49). No wrist had SLAC. In eight patients, 24 years or more after the onset of the disease, the articular surface of the radius had been remodelled by the subluxed scaphoid with maintenance of the joint space. The wrists of six patients were considered to be excellent, nine good, and one fair according to the clinical criteria of Dornan. Our findings have shown that rotatory subluxation of the scaphoid in Kienböck’s disease is not a cause of SLAC wrist and therefore that scaphotrapezio-trapezoid arthrodesis is not required for the management of these patients

We used the Ilizarov method in seven patients with severe congenital radial club hands who had had previous wrist surgery, to correct residual shortening and bowing of the ulna together with recurrent wrist deformity. The mean age at operation was 6.5 years. The mean ulnar shortening was 5.3 cm and the mean angular deformity 42°. The mean length gained was 51% of the original ulna. The mean healing index was 46.9 days (29.8 to 64.0). The ratio of the length of the lengthened ulna to the normal side improved on average from 64% to 95%. The angular deformity was initially completely corrected in six out of seven patients. The length ratio, however, decreased to 83% at the final follow-up. In four patients, the angular deformity partially recurred. We recommend correction of congenital radial club hand by staged procedures. The first is centralisation and stabilisation of the wrist and the second lengthening of the ulna and correction of the angular deformity using the Ilizarov method

Between June 1991 and May 1996 we carried out arthrodesis on 15 patients with flail or partially flail wrists using an AO/ASIF dynamic compression plate (DCP) without a bone graft. The wrist was approached through the second extensor compartment. The minimum follow-up was for 24 months with a mean of 34.2 months. All 15 wrists fused without major complications at a mean of 11.9 weeks. Stabilisation improved the function of the hand affected with paralysis and the appearance of the extensively paralysed upper limb with a flail hand. In the absence of bony abnormality fusion can be obtained with a DCP alone without the need for bone grafting

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.

1. Pain at the front of the radial side of the wrist may be caused by various lesions of the tendon and sheath of the flexor carpi radialis tendon. 2. The diagnosis may be established by testing resisted movement at the wrist and by the effect of injecting local anaesthetic into the tendon sheath. 3. In women over the age of fifty the lesion is associated with osteoarthritis of the joint between the scaphoid and the trapezium. 4. Osteoarthritis of the joint between the scaphoid and the trapezium is found in about 25 per cent of women over the age of fifty. 5. If the pain is not relieved by simple conservative measures it can usually be cured by incision of the tendon sheath. 6. The histological changes in the tendon sheath are similar to those found in tenovaginitis of the abductor pollicis longus and tibialis posterior tendons

1. A medial approach is preferred for arthrodesis of the wrist in reconstructive surgery because there is no interference with the extensor tendons. 2. The value of pre-operative assessment by a trial period in plaster is mentioned. 3. The technique of operation is described. 4. In the absence of active pronation, screwing the ulna to the radius in 45 degrees of pronation is advised. 5. The necessity for securing haemostasis before closing the wound is emphasised. 6. Thirty-four cases are reviewed. The shortest follow-up was one year and the longest twelve years. The result was satisfactory in all cases. Most patients were discharged from hospital after the plaster had been changed two weeks after operation. Union occurred in about sixteen weeks

The purpose of this study was to assess the clinical and radiological outcomes of dorsal intercarpal ligament capsulodesis for the treatment of static scapholunate instability at a minimum follow-up of four years. A total of 59 patients who underwent capsulodesis for this condition were included in a retrospective analysis after a mean of 8.25 years (4.3 to 12). A total of eight patients underwent a salvage procedure at a mean of 2.33 years (0.67 to 7.6) and were excluded. The mean range of extension/flexion was 88° (15° to 135°) and of ulnar/radial deviation was 38° (0° to 75°) at final follow-up. The mean Disabilities of the Arm Shoulder and Hand (DASH) score and Mayo wrist scores were 28 (0 to 85) and 61 (0 to 90), respectively. After significant improvement immediately post-operatively (p < 0.001 and p = 0.001, respectively), the mean scapholunate and radiolunate angles deteriorated to 70° (40° to 90°) and 8° (-15° to 25°), respectively, at final follow-up, which were not significantly different from their pre-operative values (p = 0.6 and p = 0.4, respectively). The mean carpal height index decreased significantly from 1.53 (1.38 to 1.65) to 1.48 (1.29 to 1.65) indicating progressive carpal collapse (p < 0.001); 40 patients (78%) had radiological evidence of degenerative arthritis. Capsulodesis did not maintain carpal reduction over time. Although the consequent ongoing scapholunate instability resulted in early arthritic degeneration, most patients had acceptable long-term function of the wrist

1. A case of ulnar nerve compression at the wrist caused by rheumatoid arthritis producing motor and sensory changes is presented. 2. The diagnosis from compression at the elbow can be determined by electromyography. 3. It may be that lesions of the deep branch leading to motor changes only occur in rheumatoid arthritis more often than is suspected, their effects being hidden by the concomitant disease and its associated muscle wasting

A case of unusually extensive pigmented villonodular synovitis of the wrist with involvement of bone, particularly of the distal end of the radius, is reported. The clinical and radiographic evidence suggested a diagnosis of primary bone tumour, possibly a giant-cell tumour with sarcomatous transformation

Osteoarthritis of the wrist is a complication of a number of common traumatic conditions. Arthrodesis of the radiocarpal joint, proximal row carpectomy and excision of the scaphoid, combined with midcarpal arthrodesis, have all been reported as surgical options. There have been no randomised studies comparing these procedures, and the feasibility of conducting this type of trial is limited. We used decision analysis to compare the three surgical techniques. The variables for the model used were based principally on data from the literature. Extensive sensitivity analyses were carried out to test the impact of the values given to these variables on the outcome of the model. The model indicated that the preferred treatment is proximal row carpectomy. Decision analysis allows a comparison between alternative treatments, when evidence from a randomised trial is lacking or unobtainable. The decision-analysis model may also provide insight into aspects of a problem which would be difficult, or impossible, to evaluate by a cohort study

Two girls with congenital postural deformity of the wrist associated with deformity of the feet are reported. Fetal position in utero is discussed as a likely cause, and treatment by simple manipulation is recommended

Traumatic tenosynovitis of the wrist extensors is a common and disabling condition associated with overuse. It has been found to be associated with hypertrophy of the bellies of abductor pollicis longus and extensor pollicis brevis where they overlie the radial extensor tendons in the forearm, compressing these tendons and their enveloping paratenons against the deep structures beneath. Simple surgical decompression of the sheath of these overlying muscles has been found to give quick relief of symptoms and to allow a more rapid return to strenuous work than the conservative treatments usually employed

A consecutive series of 100 cases of wrist injury, other than those referred with a radial fracture, have been reviewed to determine the incidence of acute scapholunate instability; a "clenched fist" radiograph was used in addition to the routine scaphoid views. Of 19 patients with an increase in the scapholunate gap, five were eventually considered to have significant scapholunate instability, two in association with Colles' fractures. Injuries producing significant ligamentous damage and carpal instability may be as common as scaphoid fractures. They require special consideration in diagnosis and management

Darrach's procedure was performed for post-traumatic symptoms in the inferior radio-ulnar joint in 36 patients, who were reviewed after a mean follow-up of 6 years. Only 18 of the patients had a satisfactory clinical result. Poor outcome was associated with osteoarthritis of the wrist, the occurrence of algodystrophy and a short ulnar remnant

Debate continues about the origin of Dupuytren’s disease, which is usually in the palm but is seen elsewhere as ectopic lesions. We describe a young patient with Dupuytren’s disease extending proximal to the wrist crease in continuity with the palmar lesion. Our findings support the view that the condition starts within the palmar connective tissue, but there is no palmar aponeurosis in the forearm and the proximal extension probably started in the deep layer of the superficial fascia

Malunion is the most common complication of the distal radius with many modalities of treatment available for such a problem. The use of bone grafting after an osteotomy is still recommended by most authors. We hypothesised that bone grafting is not required; fixing the corrected construct with a volar locked plate helps maintain the alignment, while metaphyseal defect fills by itself. Prospectively, we performed the procedure on 30 malunited dorsally-angulated radii using fixed angle volar locked plates without bone grafting. At the final follow-up, 22 wrists were available. Radiological evidence of union, correction of the deformity, clinical and functional improvement was achieved in all cases. Without the use of bone grafting, corrective open wedge osteotomy fixed by a volar locked plate provides a high rate of union and satisfactory functional outcomes

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.

Aims

Distal radial fractures are the most common fracture sustained by the adult population. Most can be treated using cast immobilization without the need for surgery. The aim of this study was to assess the feasibility of a definitive trial comparing the commonly used fibreglass cast immobilization with an alternative product called Woodcast. Woodcast is a biodegradable casting material with theoretical benefits in terms of patient comfort as well as benefits to the environment.

Aims

The management of completely displaced fractures of the distal radius in children remains controversial. This study evaluates the outcomes of surgical and non-surgical management of ‘off-ended’ fractures in children with at least two years of potential growth remaining.

This article is a systematic review of the published literature about the biomechanics, functional outcome and complications of intramedullary nailing of fractures of the distal radius.

We searched the Medline and EMBASE databases and included all studies which reported the outcome of intramedullary (IM) nailing of fractures of the distal radius. Data about functional outcome, range of movement (ROM), strength and complications, were extracted. The studies included were appraised independently by both authors using a validated quality assessment scale for non-controlled studies and the CONSORT statement for randomised controlled trials (RCTs).

The search strategy revealed 785 studies, of which 16 were included for full paper review. These included three biomechanical studies, eight case series and five randomised controlled trials (RCTs).

The biomechanical studies concluded that IM nails were at least as strong as locking plates. The clinical studies reported that IM nailing gave a comparable ROM, functional outcome and grip strength to other fixation techniques.

However, the mean complication rate of intramedullary nailing was 17.6% (0% to 50%). This is higher than the rates reported in contemporary studies for volar plating. It raises concerns about the role of intramedullary nailing, particularly when comparative studies have failed to show that it has any major advantage over other techniques. Further adequately powered RCTs comparing the technique to both volar plating and percutaneous wire fixation are needed.

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.

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 primary aim of this study was to assess if traumatic triangular fibrocartilage complex (TFCC) tears can be treated successfully with immobilization alone. Our secondary aims were to identify clinical factors that may predict a poor prognosis. Methods. This was a retrospective analysis of 89 wrists in 88 patients between January 2015 and January 2019. All patients were managed conservatively initially with either a short-arm or above-elbow custom-moulded thermoplastic splint for six weeks. Outcome measures recorded included a visual analogue scale for pain, Patient-Rated Wrist Evaluation, Disabilities of the Arm, Shoulder and Hand score, and the modified Mayo Wrist Score (MMWS). Patients were considered to have had a poor outcome if their final MMWS was less than 80 points, or if they required eventual surgical intervention. Univariate and logistic regression analyses were used to identify independent predictors for a poor outcome. Results. In total, 76% of wrists (42/55) treated with an above-elbow splint had a good outcome, compared to only 29% (10/34) with a short-arm splint (p < 0.001). The presence of a complete foveal TFCC tear (p = 0.009) and a dorsally subluxated distal radioulnar joint (DRUJ) (p = 0.032) were significantly associated with a poor outcome on univariate analysis. Sex, age, energy of injury, hand dominance, manual occupation, ulnar variance, and a delay in initial treatment demonstrated no significant association. Multiple logistic regression revealed that short-arm immobilization (p < 0.001) and DRUJ subluxation (p = 0.020) were significant independent predictive factors of an eventual poor outcome. Conclusion. Nonoperative management of traumatic TFCC injuries with above-elbow immobilization is a viable treatment method, particularly in patients without DRUJ subluxation. Early surgery should be considered for patients with dorsal ulnar subluxation treated with short-arm splints to prevent prolonged morbidity. Cite this article: Bone Joint J 2021;103-B(8):1386–1391

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.

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

Injury to the triangular fibrocartilage complex (TFCC) may result in ulnar wrist pain with or without instability. One component of the TFCC, the radioulnar ligaments, serve as the primary soft-tissue stabilizer of the distal radioulnar joint (DRUJ). Tears or avulsions of its proximal, foveal attachment are thought to be associated with instability of the DRUJ, most noticed during loaded pronosupination. In the absence of detectable instability, injury of the foveal insertion of the radioulnar ligaments may be overlooked. While advanced imaging techniques such as MRI and radiocarpal arthroscopy are well-suited for diagnosing central and distal TFCC tears, partial and complete foveal tears without instability may be missed without a high degree of suspicion. While technically challenging, DRUJ arthroscopy provides the most accurate method of detecting foveal abnormalities. In this annotation the spectrum of foveal injuries is discussed and a modified classification scheme is proposed. Cite this article: Bone Joint J 2023;105-B(1):5–10

Aims. The study aimed to assess the clinical outcomes of arthroscopic debridement and partial excision in patients with traumatic central tears of the triangular fibrocartilage complex (TFCC), and to identify prognostic factors associated with unfavourable clinical outcomes. Methods. A retrospective analysis was conducted on patients arthroscopically diagnosed with Palmer 1 A lesions who underwent arthroscopic debridement and partial excision from March 2009 to February 2021, with a minimum follow-up of 24 months. Patients were assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, Mayo Wrist Score (MWS), and visual analogue scale (VAS) for pain. The poor outcome group was defined as patients whose preoperative and last follow-up clinical score difference was less than the minimal clinically important difference of the DASH score (10.83). Baseline characteristics, arthroscopic findings, and radiological factors (ulnar variance, MRI, or arthrography) were evaluated to predict poor clinical outcomes. Results. A total of 114 patients were enrolled in this study, with a mean follow-up period of 29.8 months (SD 14.4). The mean DASH score improved from 36.5 (SD 21.5) to 16.7 (SD 14.3), the mean MWS from 59.7 (SD 17.9) to 79.3 (SD 14.3), and the mean VAS pain score improved from 5.9 (SD 1.8) to 2.2 (SD 2.0) at the last follow-up (all p < 0.001). Among the 114 patients, 16 (14%) experienced poor clinical outcomes and ten (8.8%) required secondary ulnar shortening osteotomy. Positive ulnar variance was the only factor significantly associated with poor clinical outcomes (p < 0.001). Positive ulnar variance was present in 38 patients (33%); among them, eight patients (21%) required additional operations. Conclusion. Arthroscopic debridement alone appears to be an effective and safe initial treatment for patients with traumatic central TFCC tears. The presence of positive ulnar variance was associated with poor clinical outcomes, but close observation after arthroscopic debridement is more likely to be recommended than ulnar shortening osteotomy as a primary treatment.

Aims. The aims of this study were to identify means to quantify coronal plane displacement associated with distal radius fractures (DRFs), and to understand their relationship to radial inclination (RI). Methods. From posteroanterior digital radiographs of healed DRFs in 398 female patients aged 70 years or older, and 32 unfractured control wrists, the relationships of RI, quantifiably, to four linear measurements made perpendicular to reference distal radial shaft (DRS) and ulnar shaft (DUS) axes were analyzed: 1) DRS to radial aspect of ulnar head (DRS-U); 2) DUS to volar-ulnar corner of distal radius (DUS-R); 3) DRS to proximal capitate (DRS-PC); and 4) DRS to DUS (interaxis distance, IAD); and, qualitatively, to the distal ulnar fracture, and its intersection with the DUS axis. Results. In the study (fracture) and control groups, respectively, the mean values were: RI, 17.2° (SD 7.2°; -7° to 35°) and 25.6° (SD 2.6°; 21° to 30°); DRS-U, 13.5 mm (SD 1.7; 4.9 to 20.8) and 15.3 mm (SD 0.72; 13.8 to 16.3); DUS-R, 13.4 mm (SD 2.1; 4.8 to 18.5) and 12.0 mm (SD 0.99; 9.7 to 13.9); DRS-PC (positive value radial to DRS, negative value ulnar), 0.14 mm (SD 5.4; -10.9 to 22.7) and -6.1 mm (SD 1.6; -10.6 to -2.3); and IAD, 25.3 mm (SD 2.5; 17.6 to 31.1) and 27.1 mm (SD 1.5; 24.5 to 31.0). All means were significantly different between the study and control groups. RI correlated strongly with DRS-PC. Ulnar styloid fracture intersection with the DUS axis, reflective of ulnar translation of both radial and ulnar shafts, was associated with significantly lower RI. Conclusion. After DRF, the relationship of the proximal capitate to the DRS axis in the coronal plane correlates with the final radial inclination. Additionally, ulnar styloid intersection with the DUS axis is associated with even lower radial inclination. DRF reduction should seek to restore the normal coronal relationship of both radial and ulnar shafts to their distal counterparts. Cite this article: Bone Joint J 2023;105-B(6):688–695

Aims. The aim of this study was to describe the introduction of a virtual pathway for the management of patients with a suspected fracture of the scaphoid, and to report patient-reported outcome measures (PROMs) and satisfaction following treatment using this service. Methods. All adult patients who presented with a clinically suspected scaphoid fracture that was not visible on radiographs at the time of presentation during a one-year period were eligible for inclusion in the pathway. Demographic details, findings on examination, and routine four-view radiographs at the time of presentation were collected. All radiographs were reviewed virtually by a single consultant hand surgeon, with patient-initiated follow-up on request. PROMs were assessed at a minimum of one year after presentation and included the abbreviated version of the Disabilities of the Arm, Shoulder and Hand Score (QuickDASH), the EuroQol five-dimension five-level health questionnaire (EQ-5D-5L), the Net Promoter Score (NPS), and return to work. Results. A total of 221 patients were referred to the virtual pathway. Their mean age was 41 years (range 16 to 87) and there were 99 male patients (45%). A total of 189 patients (86%) were discharged with advice and 19 (9%) were recalled for clinical review: seven with an undisplaced scaphoid fracture, six with another fracture of the hand or wrist, two with a scapholunate ligament injury, and four in whom no abnormality was detected. A total of 13 patients (6%) initiated follow-up with the hand service: no fracture or ligament injury was identified in this group. PROMs were available for 179 patients (81%) at a mean follow-up of 19 months (range 13 to 33). The median QuickDASH score was 2.3 (interquartile range (IQR) 0 to 15.9), the median EQ-5D-5L was 0.85 (IQR 0.73 to 1.00), the NPS was 76, and 173 patients (97%) were satisfied with their treatment. There were no documented cases of symptomatic nonunion one year following injury. Conclusion. We describe the introduction of a virtual pathway for the management of patients with a suspected scaphoid fracture. We found high levels of patient satisfaction, excellent PROMs, and no detrimental effects in the vast majority of cases. Cite this article: Bone Joint J 2022;104-B(6):709–714

Aims. The aim of this study was to compare the clinical effectiveness of Kirschner wire (K-wire) fixation with locking-plate fixation for patients with a dorsally displaced fracture of the distal radius in the five years after injury. Patients and Methods. We report the five-year follow-up of a multicentre, two-arm, parallel-group randomized controlled trial. A total of 461 adults with a dorsally displaced fracture of the distal radius within 3 cm of the radiocarpal joint that required surgical fixation were recruited from 18 trauma centres in the United Kingdom. Patients were excluded if the surface of the wrist joint was so badly displaced it required open reduction. In all, 448 patients were randomized to receive either K-wire fixation or locking-plate fixation. In the K-wire group, there were 179 female and 38 male patients with a mean age of 59.1 years (19 to 89). In the locking-plate group, there were 194 female and 37 male patients with a mean age of 58.3 years (20 to 89). The primary outcome measure was the patient-rated wrist evaluation (PRWE). Secondary outcomes were health-related quality of life using the EuroQol five-dimension three-level (EQ-5D-3L) assessment, and further surgery related to the index fracture. Results. At 12 months, 402/448 participants (90%) recruited into the main study provided PRWE scores. At year two, 294 participants (66%) provided scores; at year five, 198 participants (44%) provided scores. There was no clinically relevant difference in the PRWE at any point during the five-year follow-up; at five years, the PRWE score was 8.3 (12.5) in the wire group and 11.3 (15.6) in the plate group (95% confidence interval -6.99 to 0.99; p = 0.139). Nor was there a clinically relevant difference in health-related quality of life. Only three participants had further surgery in the five years after their injury (one in the wire group and two in the plate group). Conclusion. This follow-up study continues to show no evidence of a difference in wrist pain, wrist function, or quality of life for patients treated with wires versus locking plates in the five years following a dorsally displaced fracture of the distal radius.

Aims. Carpal malalignment after a distal radial fracture occurs due to loss of volar tilt. Several studies have shown that this has an adverse influence on function. We aimed to investigate the magnitude of dorsal tilt that leads to carpal malalignment, whether reduction of dorsal tilt will correct carpal malalignment, and which measure of carpal malalignment is the most useful. Methods. Radiographs of patients with a distal radial fracture were prospectively collected and reviewed. Measurements of carpal malalignment were recorded on the initial radiograph, the radiograph following reduction of the fracture, and after a further interval. Linear regression modelling was used to assess the relationship between dorsal tilt and carpal malalignment. Receiver operating characteristic (ROC) analysis was used to identify which values of dorsal tilt led to carpal malalignment. Results. A total of 250 consecutive patients with 252 distal radial fractures were identified. All measures of carpal alignment were significantly associated with dorsal tilt at each timepoint. This relationship persisted after adjustment for age, sex, and the position of the wrist. Capitate shift consistently had the strongest relationship with dorsal tilt and was the only parameter that was not influenced by age or the position of the wrist. ROC curve analysis identified that abnormal capitate shift was seen with > 9° of dorsal tilt. Conclusion. Carpal malalignment is related to dorsal tilt following a distal radial fracture. Reducing the fracture and improving dorsal tilt will reduce carpal malalignment. Capitate shift is easy to assess visually, unrelated to age and sex, and appears to be the most useful measure of carpal malalignment. The aim during reduction of a distal radial fracture should be to realign the capitate with the axis of the radius and prevent carpal malalignment.

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. The primary aim of this study was to describe patient satisfaction and health-related quality of life (HRQoL) following corrective osteotomy for a symptomatic malunion of the distal radius. Methods. We retrospectively identified 122 adult patients from a single centre over an eight-year period who had undergone corrective osteotomy for a symptomatic malunion of the distal radius. The primary long-term outcome was the Patient-Rated Wrist Evaluation (PRWE) score. Secondary outcomes included the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, the EQ-5D-5L score, complications, and the Net Promoter Score (NPS). Multivariate regression analysis was used to determine factors associated with the PRWE score. Results. Long-term outcomes were available for 89 patients (72%). The mean age was 57 years (SD 15) and 68 were female (76%). The median time from injury to corrective osteotomy was nine months (interquartile range (IQR) 6 to 13). At a mean follow-up of six years (1 to 11) the median PRWE score was 22 (IQR 7 to 40), the median QuickDASH score was 11.4 (IQR 2.3 to 31.8), and the median EQ-5D-5L score was 0.84 (IQR 0.69 to 1). The NPS was 69. Multivariate regression analysis showed that the presence of an associated ulnar styloid fracture was the only significant independent factor associated with a worse PRWE score when adjusting for confounding variables (p = 0.004). Conclusion. We found that corrective osteotomy for malunion of the distal radius can result in good functional outcomes and high levels of patient satisfaction. However, the presence of an ulnar styloid fracture may adversely affect function. Level of Evidence: III (cohort study). Cite this article: Bone Joint J 2020;102-B(11):1542–1548

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 aim of this study was to investigate whether intraoperative 3D fluoroscopic imaging outperforms dorsal tangential views in the detection of dorsal cortex screw penetration after volar plating of an intra-articular distal radial fracture, as identified on postoperative CT imaging. Methods. A total of 165 prospectively enrolled patients who underwent volar plating for an intra-articular distal radial fracture were retrospectively evaluated to study three intraoperative imaging protocols: 1) standard 2D fluoroscopic imaging with anteroposterior (AP) and elevated lateral images (n = 55); 2) 2D fluoroscopic imaging with AP, lateral, and dorsal tangential views images (n = 50); and 3) 3D fluoroscopy (n = 60). Multiplanar reconstructions of postoperative CT scans served as the reference standard. Results. In order to detect dorsal screw penetration, the sensitivity of dorsal tangential views was 39% with a negative predictive value (NPV) of 91% and an accuracy of 91%; compared with a sensitivity of 25% for 3D fluoroscopy with a NPV of 93% and an accuracy of 93%. On the postoperative CT scans, we found penetrating screws in: 1) 40% of patients in the 2D fluoroscopy group; 2) in 32% of those in the 2D fluoroscopy group with AP, lateral, and dorsal tangential views; and 3) in 25% of patients in the 3D fluoroscopy group. In all three groups, the second compartment was prone to penetration, while the postoperative incidence decreased when more advanced imaging was used. There were no penetrating screws in the third compartment (extensor pollicis longus groove) in the 3D fluoroscopy groups, and one in the dorsal tangential views group. Conclusion. Advanced intraoperative imaging helps to identify screws which have penetrated the dorsal compartments of the wrist. However, based on diagnostic performance characteristics, one cannot conclude that 3D fluoroscopy outperforms dorsal tangential views when used for this purpose. Dorsal tangential views are sufficiently accurate to detect dorsal screw penetration, and arguably more efficacious than 3D fluoroscopy. Cite this article: Bone Joint J 2020;102-B(7):874–880

Aims. The aim of this study was to compare patient-reported outcome measures (PROMs) and the Single Assessment Numerical Evaluation (SANE) score in patients treated with a volar locking plate for a distal radial fracture. Methods. This study was a retrospective review of a prospective database of 155 patients who underwent internal fixation with a volar locking plate for a distal radial fracture between August 2014 and April 2017. Data which were collected included postoperative PROMs (Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) and Patient-Rated Wrist Evaluation (PRWE)), and SANE scores at one month (n = 153), two months (n = 155), three months (n = 144), six months (n = 128), and one year (n = 73) after operation. Patients with incomplete data were excluded from this study. Correlation and agreement between PROMs and SANE scores were evaluated. Subgroup analyses were carried out to identify correlations according to variables such as age, the length of follow-up, and subcategories of the PRWE score. Results. The Pearson correlation coefficient (r) between PROMs and SANE scores was -0.76 (p < 0.001) for DASH and -0.72 (p < 0.001) for PRWE, respectively. Limits of agreement between PROMs and ‘100-SANE’ scores were met for at least 93% of the data points. In subgroup analysis, there were significant negative correlations between PROMs and SANE scores for all age groups and for follow-up of more than six months. The correlation coefficient between PRWE subcategories and SANE score was -0.67 (p < 0.001) for PRWE pain score and -0.69 (p < 0.001) for PRWE function score, respectively. Conclusion. We found a significant correlation between postoperative SANE and PROMs in patients treated with a volar locking plate for a distal radial fracture. The SANE score is thus a reliable indicator of outcome for patients who undergo surgical treatment for a radial fracture. Cite this article: Bone Joint J 2020;102-B(6):744–748

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

We performed a retrospective study to determine the effect of osteoporosis on the functional outcome of osteoporotic distal radial fractures treated with a volar locking plate. Between 2009 and 2012 a total of 90 postmenopausal women with an unstable fracture of the distal radius treated with a volar locking plate were studied. Changes in the radiological parameters of 51 patients with osteoporosis (group 1, mean age 66.9, mean T-score –3.16 (. sd.  0.56)) were not significantly different from those in 39 patients without osteoporosis (group 2, mean age 61.1, mean T-score –1.72 (. sd. 0.57)). The mean Disabilities of the Arm, Shoulder and Hand (DASH) score at final follow-up was 11.5 (. sd. 12.2) in group 1 and 10.5 (. sd.  13.25) in group 2. The mean modified Mayo wrist score at final follow-up was 79.0 (. sd.  14.04) in group 1 and 82.6 (. sd. 13.1) in group 2. However, this difference was not statistically significant (p = 0.35 for DASH score, p = 0.2 for modified Mayo wrist score). Univariable and multivariable logistic regression analysis showed that only the step-off of the radiocarpal joint was related to both a poor DASH and modified Mayo wrist score. Pearson’s correlation coefficient showed a weak negative relationship only between the T-score and the change in volar tilt (intraclass coefficient –0.26, p = 0.02). We found that osteoporosis does not have a negative effect on the functional outcome and additional analysis did not show a correlation between T-score and outcome.

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

Aims. The aim of this study was to evaluate the outcome of Monteggia-like lesions at midterm follow-up and to determine whether the surgical treatment of the radial head influences the clinical and radiological results. Patients and Methods. A total of 78 patients with a Monteggia-like lesion, including 44 women and 34 men with a mean age of 54.7 years (19 to 80), were available for assessment after a mean 4.6 years (2 to 9.2). The outcome was assessed using the Mayo Elbow Performance Score (MEPS), Oxford Elbow Score (OES), Mayo Modified Wrist Score (MMWS), and The Disabilities of the Arm, Shoulder and Hand (DASH) score. Radiographs were analyzed for all patients. A total of 12 Mason type I, 16 type II, and 36 type III fractures were included. Surgical treatment consisted of screw fixation for all type II and reconstructable type III fractures, while radial head arthroplasty (RHA) or excision was performed if reconstruction was not possible. Results. The mean MEPS was 88.9 (40 to 100), mean OES was 40.1 (25 to 48), mean MMWS was 88.1 (50 to 100), mean DASH score was 14.7 (0 to 60.2), and mean movement was 114° (. sd. 27) in extension/flexion and 155° (. sd. 37) in pronation/supination. Mason III fractures, particularly those with an associated coronoid fracture treated with RHA, had a significantly poorer outcome. Suboptimal results were also identified in patients who had degenerative changes or heterotopic ossification on their latest radiograph. In contrast, all patients with successful radial head reconstruction or excision had a good outcome. Conclusion. Good outcomes can be achieved in Monteggia-like lesions with Mason II and III fractures, when reconstruction is possible. Otherwise, RHA is a reliable option with satisfactory outcomes, especially in patients with ligamenteous instability. Whether the radial head should be excised remains debatable, although good results were achieved in patients with ligamentous stability and in those with complications after RHA.

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
