Background and purpose Promising results have been reported after volar locked plating of unstable dorsally displaced distal radius fractures. We investigated whether volar locked plating results in better patient-perceived, objective functional and radiographic outcomes compared to the less invasive external fixation.Patients and methods 63 patients under 70 years of age, with an unstable extra-articular or non-comminuted intra-articular dorsally displaced distal radius fracture, were randomized to volar locked plating (n = 33) or bridging external fixation. Patient-perceived outcome was assessed with the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and the Patient-Rated Wrist Evaluation (PRWE) questionnaire.Results At 3 and 6 months, the volar plate group had better DASH and PRWE scores but at 12 months the scores were similar. Objective function, measured as grip strength and range of movement, was superior in the volar plate group but the differences diminished and were small at 12 months. Axial length and volar tilt were retained slightly better in the volar plate group.Interpretation Volar plate fixation is more advantageous than external fixation, in the early rehabilitation period.

The tendency of 267 consecutive Colles' fractures to dislocate during plaster-cast treatment was correlated with several parameters measured from the initial radiographs. Stepwise logistic regression analysis showed that radial axial shortening had the greatest prognostic power. The age of the patient and Lidström's class provided additional prognostic information. Initial radial axial shortening of 5 mm or more generally indicated an unfavorable anatomic end result.

The patient-rated wrist evaluation (PRWE) form is an established outcome questionnaire designed to measure wrist pain and disabilities in activities of daily living. We translated and validated this score for use in Sweden. The original PRWE score was translated forwards and backwards, and then the responsiveness, validity, and reliability of the Swedish version were tested in 99 patients who were recovering from a fracture of the distal radius. The patients completed the PRWE questionnaire 7 weeks and 4 to 6 months after the injury. Responsiveness was assessed by Standard Response Mean and Effect Size. Content validity was evaluated by examining the proportion of best and worse possible scores. Construct validity was assessed by comparing scores twice after the injury and by comparing patients with fractures of different severity. Criterion validity was evaluated by correlating the PRWE with another upper extremity score: the disability of the arm, shoulder, and hand (DASH) score. Reliability was evaluated with a test-retest and by internal consistency. Responsiveness was excellent (SRM = 1.4-1.7, ES = 1.3). Five patients reported the best possible result after 4 to 6 months but none at 7 weeks, and no patient reported the worst score at any time. The PRWE score corresponded well with improvement and showed good correlation with severity of fracture. The PRWE showed a strong correlation with DASH score (Spearman's rank coefficient = 0.86). Intraobserver reliability of the test-retest and internal consistency was good (Kendall W coefficient = 0.79, Spearman's rank coefficient = 0.99, Cronbach's alpha = 0.94-0.97). We found this Swedish version of the PRWE to be responsive, valid, and reliable for evaluating the patient-rated outcome after a fracture of the distal radius.

It would be a great advantage if it were possible to categorise the patients with first time dislocations to an initial treatment with the most beneficial outcome. MRI could be a useful method for finding lesions after shoulder dislocation. Fifty-eight patients with traumatic anterior shoulder dislocation were treated by closed reduction and were examined by MRI after a maximum of 2 weeks. The hemarthrosis or effusion present in the joint after the primary dislocation could be used as a contrast for arthrography to identify the lesions present on MRI. At follow-up more than 8 years later, the MRI findings were compared to the shoulder function, shoulder stability, Rowe score and Western Ontario Shoulder Instability Index (WOSI). Besides the age of the patient being above 30, the MRI findings analysed showed that an isolated fracture of the major tubercle, as well as a bony Bankart lesion are prognostic factors for a good functional result and a stable shoulder after a primary dislocation. The glenoid rim fracture was only detected on plain radiographs in 6 out of 10 findings on MRI. MRI findings of a gleniod rim fracture, equal to a bony Bankart lesion, were found to be a prognostic factor for stability and a good functional outcome.
