Functional performance of the upper limb and the most common boxing-related injuries in male boxers: a retrospective, observational, comparative study with non-boxing population

BackgroundTo investigate the functional status and recording the most common injuries of the upper limb in male Greek boxing squad in comparison to the general population.MethodsA retrospective injury surveillance study using an electronic questionnaire was performed in 2021. The questionnaire was sent to male members of the Greek Boxing Federation and consisted of three parts. Demographic data, functional status scales, training conditions, hours of training, the location and description of upper limb injuries and whether the injury occurred during competition or training and also whether it was a new or a recurrent one were gathered. The same questionnaire was sent to non-boxer males (military recruits), but without asking them to report any training parameters. Inclusion criteria were age < 35 years-old for all participants and no involvement in martial arts for the control group. Also, all participants (boxers and non-boxers) completed the Patient Rated Wrist Evaluation (PRWE) scale and the Quick Disabilities of Arm, Shoulder and Hand (quick-DASH) score.ResultsThe final study cohort was consisted of 62 elite or amateur boxers and 75 non-boxer males, less than 35 years old. The quick-DASH score was found to be significantly lower (better) in boxers in comparison to the general population (15.65 ± 10.25 vs. 12.55 ± 8.62; p = 0.020) whereas the PRWE score was similar in both groups (9.25 ± 14.96 vs. 8.61 ± 13.05; p = 0.843). Physical therapy sessions, thumb injuries and boxer’s knuckle were also found to be significantly higher in the boxers group. On the other hand, upper limb surgeries were significantly less in the boxers group. Finally, the size of boxing gloves was associated to the number of finger fractures, thumb injuries and ulnar sided wrist pain in boxers.ConclusionsAlthough a controversial sport, boxing appears to have no long-term consequences to the upper limb function, especially regarding hand performance. The size of gloves during heavy bag training was found to be an aggravating factor for hand injuries.

Functional outcome and patient satisfaction with a 'self-care' protocol for minimally displaced distal radius fractures : a service evaluation.

AimsWe introduced a self-care pathway for minimally displaced distal radius fractures, which involved the patient being discharged from a Virtual Fracture Clinic (VFC) without a physical review and being provided with written instructions on how to remove their own cast or splint at home, plus advice on exercises and return to function.MethodsAll patients managed via this protocol between March and October 2020 were contacted by a medical secretary at a minimum of six months post-injury. The patients were asked to complete the Patient-Rated Wrist Evaluation (PRWE), a satisfaction questionnaire, advise if they had required surgery and/or contacted any health professional, and were also asked for any recommendations on how to improve the service. A review with a hand surgeon was organized if required, and a cost analysis was also conducted.ResultsOverall 71/101 patients completed the telephone consultation; no patients required surgery, and the mean and median PRWE scores were 23.9/100 (SD 24.9) and 17.0/100 (interquartile range (IQR) 0 to 40), respectively. Mean patient satisfaction with treatment was 34.3/40 (SD 9.2), and 65 patients (92%) were satisfied or highly satisfied. In total there were 16 contact calls, 12 requests for a consultant review, no formal complaints, and 15 minor adjustment suggestions to improve patient experience. A relationship was found between intra-articular injuries and lower patient satisfaction scores (p = 0.025), however no relationship was found between PRWE scores and the nature of the fracture. Also, no relationship was found between the type of immobilization and the functional outcome or patient satisfaction. Cost analysis of the self-care pathway V traditional pathway showed a cost savings of over £13,500 per year with the new self-care model compared to the traditional model.ConclusionOur study supports a VFC self-care pathway for patients with minimally displaced distal radius fractures. The pathway provides a good level of patient satisfaction and function. To improve the service, we will make minor amendments to our patient information sheet.Cite this article: Bone Jt Open 2022;3(9):726–732.

Three-Dimensionally Planned and Printed Patient-Tailored Plates for Corrective Osteotomies of the Distal Radius and Forearm

We evaluated the 1-year postoperative clinical and patient-reported outcomes in patients who had a 3-dimensional planned corrective osteotomy of their distal radius, radial shaft, or ulnar shaft using a printed, anatomical, patient-tailored plate to determine the feasibility and effectiveness of this methodology. Simulations in computer-assisted preoperative planning of corrective osteotomies resulted in 3-dimensionally printed surgical guides, surgical models, and anatomically customized plates for application at the distal radius and forearm. Patients with malunions of the distal radius or forearm who underwent fixation with the custom-made plates were documented in our registry. Grip strength and range of motion assessments were made before surgery (baseline), as well as at 6 weeks and 3 and 12 months. Additionally, patients rated their wrist-related pain and disability using the Patient-Rated Wrist Evaluation. Fifteen patients underwent corrective surgery, and the 1-year follow-up data of 14 patients with a median age of 56 years (interquartile range, 24-64 years) were available for analysis. The median baseline Patient-Rated Wrist Evaluation score improved from 47 to 7 after 1 year. The flexion-extension arc of motion of the wrist increased from 90° at baseline to 130° at 1 year and the pronation-supination arc of motion of the wrist increased from 135° to 160° in the same time period. Differences in radiological measurements for palmar and radial inclinations, as well as for ulnar variance between the affected and contralateral wrists, were reduced with the osteotomy. In 1 case, the plate was removed 11 months after the osteotomy. No severe adverse events were reported. Three-dimensionally planned and printed patient-tailored plates offer a reliable method for correcting even complex malunions of the distal radius and forearm. Therapeutic IV.

Outcomes of distal radial endoprostheses for tumour reconstruction: a single centre experience over 15 years.

We report a retrospective study over a 15-year period, between 2005 and 2020, evaluating clinical and functional outcomes in patients who underwent reconstruction of the distal radius with an endoprosthetic replacement following excision of both malignant and aggressive benign bone tumours. Data was collected retrospectively from a prospectively maintained electronic database, and prospectively via telephone patient consultation. Musculoskeletal Tumour Society and patient-rated wrist evaluation scores were assessed at a minimum of 1 year postoperatively. Of nine implants, five were arthrodeses and four were arthroplasties. One patient required amputation within 6 months for proximal metastatic disease. At last follow-up, eight patients subjectively reported good function. Five patients returned to high functionally demanding jobs. Mean Musculoskeletal Tumour Society and patient-rated wrist evaluation scores were 72% and 50/100, respectively. We conclude that distal radius endoprosthetic replacements offer acceptable functional outcomes and remain a viable option when biological reconstruction is not possible.Level of evidence: IV.

Long-term functional outcomes after total wrist arthrodesis

Current literature surrounding functional outcomes after total wrist arthrodesis is limited by short follow-up or limited use of validated patient reported outcome measures (PROMs). The primary aim of this study was to describe long-term functional outcomes following wrist arthrodesis. Secondary aims were to describe the incidence of complications and patient satisfaction. This was a retrospective single-center study. Patients with a minimum of 10-year follow-up completed a questionnaire including the Patient-Rated Wrist Evaluation (PRWE), the Quick version of the Disabilities of the Arm, Shoulder and Hand (Quick-DASH) score, the EQ-5D-5L score, and a question assessing satisfaction. Presence of a complication was also assessed. During the study period 66 patients underwent total arthrodesis. At a median follow-up of 15 years, complete patient reported outcomes were available for 34 patients. Thirty-two patients were lost to follow-up. Mean age at surgery was 49 and 16 patients were female. Mean PRWE and Quick-DASH scores were 44.8 (SD 27.7; range 0–96) and 41.9 (SD 23.6; range 2.3–97.7) respectively. Twenty-eight patients were satisfied. Nine patients reported complications. There were six cases of hardware removal and two cases of prominent metalwork. One patient underwent revision surgery for non-union. Presence of a complication did not affect the Quick-DASH or PRWE scores. Median EQ-5D-5L score was 0.7. This long-term follow-up suggests high levels of patient satisfaction and health related quality of life, despite significant functional disability. The complication rates are not insignificant, although the presence of a complication did not affect functional outcomes.

Volar Locking Plate Compared With Combined Plating of AO Type C Distal Radius Fractures: A Randomized Controlled Study of 150 Cases

The optimal way to stabilize intra-articular distal radius fractures is unclear despite recent advances in surgical management. Volar plating is the most common treatment but may not be sufficient for more complex intra-articular AO type C fractures. The purpose of this randomized controlled study was to evaluate the radiographic and clinical outcomes following surgical treatment of AO type C distal radius fractures, comparing volar with combined plating. In this study, 150 patients were randomized to volar locking plate (n= 75) or combined plating (n= 75) following a distal radius fracture AO type C. The 1-year follow-up included radiographic outcome (Batra score), visual analog scale pain score, hand grip strength, wrist range of motion, Patient-Rated Wrist Evaluation score, and Quick Disabilities of the Arm, Shoulder, and Hand score. Overall, 147 patients (median age 61 years) completed the 1-year follow-up (73 patients with volar plate and 74 with combined plating). No difference was found in radiographic outcome between the treatment groups. The volar plate group had significantly better Patient-Rated Wrist Evaluation scores, Quick Disabilities of the Arm, Shoulder, and Hand scores, hand grip strength, visual analog scale scores during activity, and flexion, extension, ulnar and radial deviation than the combined plate group. Hardware removal was performed in 10% in the volar plate group and in 31% in the combined plate group. There was no postoperative infection in the volar plate group but 3 cases in the combined plate group. In patients with complex AO type C intra-articular fractures, volar and combined plating yielded the same radiographic result. The differences in Patient-Rated Wrist Evaluation and Quick Disabilities of the Arm, Shoulder, and Hand scores between the groups did not reach the thresholds for minimal clinically important differences, suggesting similar clinical outcome. The combined plating group had a considerably higher frequency of hardware removal and postoperative infections. Therapeutic I.

Treatment Outcomes of All Arthroscopic 4-Corner Arthrodesis Techniques With 2 Headless Screws

Scaphoid excision with 4-corner arthrodesis is a safe procedure that relieves pain while also preserving the functional movements of the wrist. Different techniques have been described with successful results. In this study, we present the midterm clinical outcomes of 17 patients who underwent treatment with our arthroscopic 4-corner arthrodesis technique. Patients with at least 1 year of follow-up were included in our study. Preoperative and postoperative radiologic, functional, and clinical results were compared. Radiologic and clinical union were achieved in all patients. Significant improvement was observed in Quick Disabilities of the Arm, Shoulder, and Hand, Mayo Wrist Score, visual analog scale, and Patient-Rated Wrist Evaluation scores. Although wrist range of motion increased in the radioulnar plane, no clinically important change was observed in the flexion-extension arc. The patients were able to return to work in an average of 10 weeks. The arthroscopic 4-corner arthrodesis technique is a method with satisfactory outcomes. The main disadvantage of this procedure is that it requires a lengthy operative time, and both specific expertise and equipment. Therapeutic IV.

Computer-assisted correction of incongruent distal radioulnar joints in patients with symptomatic ulnar-minus variance

Our study described a computer-assisted, three-dimensional (3-D), planned surgical technique of a radial shortening osteotomy. The osteotomy of the distal radius was planned with computer assistance on 3-D bone models based on computed tomography data. The objective was to maximize the contact zone of the sigmoid notch with the ulnar head. Between 2012 and 2020 we treated 14 wrists in 11 patients with symptomatic ulnar-minus variance with a mean follow-up of 44 months (range 8 to 98) and a mean age of 28 years (range 19 to 38). Postoperatively, patients showed a decrease in pain at rest and during effort (numeric rating scale from 4.4 to 0 and 7.5 to 4.5, respectively). The range of motion postoperatively was similar to the contralateral side. Grip strength increased from 24 kg to 30 kg. The Disability of the Arm, Shoulder, and Hand and the Patient-Rated Wrist Evaluation scores were 28 and 35 postoperatively, respectively. Our technique of 3-D computer-assisted distal radioulnar joint reconstruction led to a pain reduction and improvement of the hand function in patients with symptomatic ulnar-minus variance.Level of evidence: IV

Arthroscopic management of traumatic TFCC tears

Background: Triangular fibrocartilage complex is a critical component of wrist biomechanics, serving important functions in both load transmission and distal radioulnar joint stability. This work aimed to assess the clinical outcome of wrist arthroscopy in the management of triangular fibrocartilage traumatic tears as a diagnostic aid and definitive therapeutic tool in terms of functional restoration, and patients’ satisfaction. Methods: This prospective study included 27 patients diagnosed with TFCC tear. Patients were categorized in two groups: group I: had arthroscopic TFCC debridement for central tears and group II: had an arthroscopic assisted capsular TFCC repair. All patients were subjected to ulna carpal stress test, ballottement of the DRUJ, hand grip, evaluation scores [visual analogue scale, Mayo wrist score and patient-rated wrist evaluation score] and radiographic evaluation. Results: PRWE score was signifcantly improved in patients to whom TFCC debridement was done P &lt;0.01. In patients to whom TC repair was done reported overall improvement of the PRWE score P &lt; 0.02. Conclusions: The two patterns of tears included, and the short term follow up period, but has shown significant improvement following the arthroscopic intervention chosen for each pattern in a reproducible and predictable manner in the majority of our series.

A Comparison of Arc of Motion, Radiological Parameters of the Wrist and Patient Rated Wrist Evaluation between Adult Transfusion Dependent Thalassemics and Normal Subjects.

Background: Bony deformities and arthropathies have been noticed in thalassemia patients. The aim of this study is to compare the arc of motion and radiological parameters of the wrist and patient rated wrist evaluation (PRWE) between adult transfusion-dependent thalassemics and normal subjects. Methods: An observational cross-sectional study was done in the department of orthopaedics over a period of 2 years where a total of 30 skeletally mature thalassemia major patients (group A) were assessed. The data was then compared with the data of demographically matched 30 healthy adults (group B). Arc of motion of the dominant wrist that included flexion, extension, radial and ulnar deviation, pronation and supination was measured using a handheld goniometer for both groups. Radiographs of the dominant wrist were obtained in both groups and used to determine the radial height, radial articular angle and carpal slip. PRWE was used to assess the function of the wrist. A p-value of <0.05 was considered statistically significant. Results: Clinical abnormalities at the wrist joint were found in 80% of thalassaemia patients. There was a statistically significant increase in ulnar deviation, wrist extension and decrease in wrist flexion in group A compared to group B. Radiological abnormalities were found in 100% of thalassaemia patients. All the radiological parameters were significantly increased in group A compared to group B. There were no differences in PRWE scores between both groups. Conclusion: Clinical and radiological changes of wrist joint occur in skeletally mature thalassaemia major patients due to shortened ulna compared to healthy adults. This may be due to disease itself, bone marrow expansion, osteopenia, drug (chelating agent) or iron toxicity. Understanding the changes at the wrist in patients with thalassemia major is important to increasing the life expectancy of these patients. Level of Evidence: Level IV (Diagnostic).

Plating vs Closed Reduction for Fractures in the Distal Radius in Older Patients

Distal radius fractures are common and are managed with or without surgery. Current evidence indicates surgical treatment is not superior to nonsurgical treatment at 12 months. Does surgical treatment for displaced distal radius fractures in patients 60 years or older provide better patient-reported wrist pain and function outcomes than nonsurgical treatment at 24 months? In this secondary analysis of a combined multicenter randomized clinical trial (RCT) and a parallel observational study, 300 patients were screened from 19 centers in Australia and New Zealand. Of these, 166 participants were randomized to surgical or nonsurgical treatment. Participants who declined randomization (n = 134) were included in the parallel observational group with the same treatment options and follow-up. Participants were followed up at 3, 12, and 24 months by a blinded assessor. The 24-month outcomes are reported herein. Data were collected from December 1, 2016, to December 31, 2020, and analyzed from February 4 to October 21, 2021. Surgical treatment consisting of open reduction and internal fixation using a volar-locking plate (VLP group) and nonsurgical treatment consisting of closed reduction and cast immobilization (CR group). The primary outcome was patient-reported function using the Patient-Rated Wrist Evaluation (PRWE) questionnaire. Secondary outcomes included health-related quality of life, wrist pain, patient-reported treatment success, patient-rated bother with appearance, and posttreatment complications. Among the 166 randomized and 134 observational participants (300 participants; mean [SD] age, 71.2 [7.5] years; 269 women [89.7%]), 151 (91.0%) randomized and 118 (88.1%) observational participants were followed up at 24 months. In the RCT, no clinically important difference occurred in mean PRWE scores at 24 months (13.6 [95% CI, 9.1-18.1] points for VLP fixation vs 15.8 [95% CI, 11.3-20.2] points for CR; mean difference, 2.1 [95% CI, -4.2 to 8.5]; P = .50). There were no between-group differences in all other outcomes except for patient-reported treatment success, which favored VLP fixation (33 of 74 [44.6%] in the CR group vs 54 of 72 [75.0%] in the VLP fixation group reported very successful treatment; P = .002). Rates of posttreatment complications were generally low and similar between treatment groups, including deep infection (1 of 76 [1.3%] in the CR group vs 0 of 75 in the VLP fixation group) and complex regional pain syndrome (2 of 76 [2.6%] in the CR group vs 1 of 75 [1.3%] in the VLP fixation group). The 24-month trial outcomes were consistent with 12-month outcomes and with outcomes from the observational group. Consistent with previous reports, these findings suggest that VLP fixation may not be superior to CR for displaced distal radius fractures for patient-rated wrist function in persons 60 years or older during a 2-year period. Significantly higher patient-reported treatment success at 2 years in the VLP group may be attributable to other treatment outcomes not captured in this study.

Total Wrist Arthroplasty with Integra Freedom® Implants: A Pilot Study with a New Evaluation System.

Recent innovations in wrist arthroplasty implants have led to remarkable improvements in terms of results with improved stability and preservation of bone stock. Despite the advances in such implants, poor outcomes and frequent complications still affect this procedure, not allowing a wider use of this treatment in wrist arthritis.The purpose of this study is to assess the preliminary mid-term results of a Wrist Arthroplasty System (Freedom®, Integra Lifesciences, Princeton, USA) in patients with rheumatoid arthritis or secondary osteoarthritis of the wrist and to propose a new classification system. We examined 12 patients (7 with rheumatoid arthritis and 5 with secondary osteoarthritis of the wrist) who underwent total wrist arthroplasties performed by a single surgeon using the fourth-generation prosthesis. Pre- and post-operative pain on a visual analogue score, functional parameters measured with Mayo Wrist score, patient-rated wrist evaluation score, range of motion, and radiographic analysis were collected. At a mean follow-up of 48 (SD 16.9) months a significant improvement (p < 0.0001) of the mean visual analogue, Mayo and PRWE scores following total wrist arthroplasty was observed. Wrist movements improved significantly (p < 0.001). We achieved significant improvements in pain relief, performance, and satisfaction both in rheumatic and non-rheumatic patients, confirmed by our scoring system. Level IV, case series.

The effects of partial wrist denervation in wrist osteoarthritis: patient-reported outcomes and objective function.

This prospective longitudinal study aimed to analyse the effect of partial wrist denervation on patient-reported outcomes, quality of life and objective function in symptomatic wrist osteoarthritis during the first year after surgery. Sixty consecutive patients underwent an anterior and posterior interosseous neurectomy during 2018–2020. Disabilities of the Arm, Shoulder and Hand, Patient-Rated Wrist Evaluation, EuroQol-5D-3L, pain at rest and on load, and objective function were assessed preoperatively and 3, 6 and 12 months postoperatively. Generalized estimating equations were used to analyse the effect on the outcome variables. Disabilities of the Arm, Shoulder and Hand, Patient-Rated Wrist Evaluation and pain scores improved significantly postoperatively with no decline over time, but no patient reported outcome measure reached the minimal clinically important difference. Quality of life, strength and range of motion did not improve. We found no complications. Seventeen patients needed further surgery during the study period. More studies are needed to evaluate whether denervation is truly effective or not.Level of evidence: II

Trapeziectomy and Alternative Suspension Technique in Thumb Carpometacarpal Arthritis: Patient-Reported Outcome Measures

PurposeFor treatment of carpometacarpal thumb joint osteoarthritis, a trapeziectomy with an alternative suspension technique can be performed as the primary surgery or as the secondary after a failed primary surgery. This study evaluates the midterm follow-up (median, 54 months) for this technique using patient-reported outcome measures.MethodsAfter trapeziectomy, an alternative suspension technique is performed with a flexor carpi radialis tendon strip. Leaving the insertion intact, the strip is tunneled through a drill hole in the base of the first metacarpal and then through a drill hole in the second metacarpal neck and then sutured back onto itself. This suspends the first metacarpal to the shaft of the second metacarpal, creating a strong, V-shaped suspension. As the technique is performed in both the primary and secondary surgery, we analyzed both groups separately. As the primary outcome, we evaluated pain and function with the Patient-Rated Wrist and Hand Evaluation. Further, we evaluated the Disabilities of the Arm, Shoulder and Hand and Short Form 12 questionnaire scores from eligible patients. Finally, we correlated pain and function to quality of life.ResultsThe median Patient-Rated Wrist and Hand Evaluation score was 16.0 (interquartile range, 1.5–40.4) after the primary surgery and 46 (interquartile range, 34.0–75.5) after the secondary surgery. Patients after the primary surgery also scored better on the Disabilities of the Arm, Shoulder, and Hand questionnaire compared to patients after the secondary surgery. The Short Form 12 questionnaire physical scores were negatively correlated with the Disabilities of the Arm, Shoulder, and Hand questionnaire scores for the primary group (correlation coefficient, −0.468) and negatively correlated with the Patient-Rated Wrist and Hand Evaluation pain scores for the secondary group (correlation coefficient, −0.703).ConclusionsTrapeziectomy with this alternative suspension technique for treatment of carpometacarpal thumb joint osteoarthritis shows good patient-reported outcome measures for primary surgery and poor patient-reported outcome measures after the secondary surgery.Type of study/level of evidenceTherapeutic IV.

Radiological, Clinical, and Functional Outcomes of Combined Dorsal and Volar Locking Plate Osteosynthesis for Complex Distal Radius Fractures

The purpose of this study was to assess the short- to mid-term radiologic, clinical, and functional outcomes of patients treated with combined dorsal and volar locking plating for internal fixation of complex, comminuted, intra-articular, distal radius fractures. We performed a retrospective review of 34 patients treated with combined dorsal and volar locking plates for the internal fixation of complex, comminuted, intra-articular distal radius fractures. Radiographic and clinical parameters were recorded at a mean of 48 months after surgery. Activities of daily living and quality of life were assessed by the Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation questionnaires. Compared with the contralateral wrist, the treated wrist regained 73% of flexion, 81% of extension, 86% of ulnar deviation, 90% of radial deviation, 98% of pronation, 99% of supination, and 93% of grip strength. Mean Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation scores were 11 (range, 0-78) and 11 (range, 0-77), respectively. Radial height and radial inclination were restored anatomically in 24% and 41% of patients, respectively, while volar tilt and ulnar variance were restored in 68% of patients. The overall functional and radiologic outcome of patients with comminuted intra-articular complex distal radius fractures treated with the combined dorsovolar plate osteosynthesis was good to excellent.

Outcomes of Arthroscopic-Assisted Distal Radius Fracture Volar Plating: A Meta-Analysis

The use of wrist arthroscopy to assist fixation of distal radius fractures with volar locking plates (VLPs) has been gaining popularity in recent years; however, there is no consensus on its benefits. This meta-analysis compares outcomes of arthroscopic-assisted VLP to fluoroscopic-assisted VLP in distal radius fractures through a systematic review of the published literature. A systematic search of publications from databases (Medline, EMBASE, Scopus, and Cochrane) was obtained from inception to May 2020. A random-effects meta-analysis was used to calculate effect sizes. Outcomes included postoperative radiographic reduction (gap, stepoff, radial inclination, volar tilt, and ulnar variance), procedural outcomes (operative time, additional soft tissue injuries and complications), and functional outcomes (range of motion; visual analog scale score; Disabilities of the Arm, Shoulder, and Hand score; Patient-Rated Wrist Evaluation score; Mayo clinic score; and grip strength). Six studies, involving 280 patients, met the final inclusion criteria. The meta-analysis for postoperative stepoff was statistically significant, favoring arthroscopic-assisted VLP. In addition, there was greater identification of associated soft tissue injuries, increased wrist extension, and a longer operative duration when performing arthroscopic-assisted VLP fixation. There were no differences in other postoperative radiographic outcomes, complications, or functional outcomes. The current literature suggests that arthroscopic-assisted VLP is a useful adjunct to intra-articular reduction and treatment of associated soft tissue injuries in distal radius fractures. Considerations should include operative time, costs, and the additional training required. Further studies are needed to assess functional outcomes. Therapeutic II.

Moulded cast compared with K-wire fixation after manipulation of an acute dorsally displaced distal radius fracture: the DRAFFT 2 RCT.

Patients with a displaced fracture of the distal radius are frequently offered surgical fixation. Manipulation of the fracture and moulded plaster casting is an alternative treatment that avoids metal implants, but evidence of its effectiveness is lacking. To compare functional outcomes, quality-of-life outcomes, complications and resource use among patients with a dorsally displaced fracture of the distal radius treated with manipulation and surgical fixation with Kirschner wires (K-wires) and those treated with manipulation and moulded cast. Pragmatic, superiority, multicentre, randomised controlled trial with a health economic evaluation. A total of 36 orthopaedic trauma centres in the UK NHS. Patients (aged ≥ 16 years) treated for an acute dorsally displaced fracture of the distal radius were potentially eligible. Patients were excluded if their injury had occurred > 2 weeks previously, if the fracture was open, if it extended > 3 cm from the radiocarpal joint or if it required open reduction, or if the participant was unable to complete questionnaires. Participants were randomly assigned in theatre (1 : 1) to receive a moulded cast (i.e. the cast group) or surgical fixation with K-wires (i.e. the K-wire group) after fracture manipulation. The primary outcome measure was the Patient-Rated Wrist Evaluation score at 12 months, analysed on an intention-to-treat basis. Health-related quality of life was recorded using the EuroQol-5 Dimensions, five-level version, and resource use was recorded from a health and personal social care perspective. Between January 2017 and March 2019, 500 participants (mean age 60 years, 83% women) were randomly allocated to receive a moulded cast (n = 255) or surgical fixation with K-wire (n = 245) following a manipulation of their fracture. A total of 395 (80%) participants were included in the primary analysis at 12 months. There was no difference in the Patient-Rated Wrist Evaluation score at 1 year post randomisation [cast group: n = 200, mean score 21.2 (standard deviation 23.1); K-wire group: n = 195, mean score 20.7 (standard deviation 22.3); adjusted mean difference -0.34 (95% confidence interval -4.33 to 3.66); p = 0.87]. A total of 33 (13%) participants in the cast group required surgical fixation for loss of fracture position in the first 6 weeks, compared with one participant in the K-wire group (odds ratio 0.02, 95% confidence interval 0.001 to 0.10). The base-case cost-effectiveness analysis showed that manipulation and surgical fixation with K-wires had a higher mean cost than manipulation and a moulded cast, despite similar mean effectiveness. The use of K-wires is unlikely to be cost-effective, and sensitivity analyses found this result to be robust. Because the interventions were identifiable, neither patients nor clinicians could be blind to their treatment. Surgical fixation with K-wires was not found to be superior to moulded casting following manipulation of a dorsally displaced fracture of the distal radius, as measured by Patient-Rated Wrist Evaluation score. However, one in eight participants treated in a moulded cast required surgery for loss of fracture reduction in the first 6 weeks. After a successful closed reduction, clinicians may consider a moulded cast as a safe and cost-effective alternative to surgical fixation with K-wires. Further research should focus on optimal techniques for immobilisation and manipulation of this type of fracture, including optimal analgesia, and for rehabilitation of the patient after immobilisation.

Distal ulna fractures in adults—subcapitular, transverse fractures did not benefit from surgical treatment

IntroductionFractures of the distal ulna, excluding the styloid, are rare. The cause of injury is often a fall on an outstretched hand with an extended wrist, and in most cases there is a concomitant distal radius fracture. The aims of this retrospective study were to investigate the results of the current treatment of distal ulna fractures in adults, with or without a concomitant distal radius fracture, and if a recently presented fracture classification could predict outcome.Materials and methodsPatients, 18 years or older, treated for a fracture of the distal third of ulna in our county, were included. Fractures of the styloid tip were excluded. The radiographs of the fractures were independently classified by two specialists in radiology according to the 2018 AO/OTA classification. Follow-up was performed 5–7 years after the injury, through the questionnaire Patient-Rated Wrist Evaluation (PRWE) and new radiographs of both wrists.ResultsNinety-six patients with 97 fractures were included and filled out the PRWE. 65 patients also had new radiographs taken. 79 patients were women and the mean age at the time of injury was 63 years (SD 14.5). The most common fracture class was the extra-articular transverse fracture, 2U3A2.3 (42%). We found that 40% of the fractures had been treated by internal fixation and only 2 fractures had not healed, one conservatively treated and one operated. The median PRWE was 15 (IQR 33.5). The PRWE score was significantly worse in the operated ulna fractures (p = 0.01) and this was also true for extra-articular transverse fractures 2U3A2.3 (p = 0.001). Initial displacement was more common in operated transverse fractures, but it could not be proven that this was the reason for the inferior result.ConclusionsDistal ulna fractures almost always unite and the result is comparable to that of isolated distal radius fractures when measured by PRWE. Based on the opinions of the radiologists and how often a consensus discussion was needed for classification, we found the updated AO classification system difficult to use, if dependent only on standard radiographic views. In the present study, transverse extra-articular ulna fractures did not benefit from internal fixation regardless if associated with a distal radius fracture or isolated.
