Randomized Controlled Trial
The dynamic vacuum orthosis: a functional and economical benefit?
In a prospective, randomised study, 27 patients with internally fixed ankle fractures were treated post-operatively for a period of six weeks by application of either a new dynamic vacuum orthosis with permitted mobilisation to 10 degrees -0 degrees -10 degrees at the ankle joint or a synthetic cast. Full weight bearing was allowed in both groups after two weeks. The cast group was prescribed four weeks of physiotherapy following six weeks of immobilisation. ⋯ Rehabilitation of ankle fractures with a dynamic vacuum orthosis leads to better early functional results and greater patient satisfaction. The orthosis fulfils the conditions for early return to work. Treatment with an orthosis not only reduces working time for medical personnel but economises on expenditure for treatment and rehabilitation.

Most gunshot injuries to the hand involve a combination of tissue types. The goal of this study is to report the results of early definitive treatment in extra-articular metacarpal and proximal phalangeal fractures due to low velocity gunshot wounds and to analyse their outcomes. A retrospective analysis of 51 metacarpal and 41 proximal phalangeal fractures of 76 patients due to low velocity gunshot wounds treated between January 2001 and December 2004 was carried out. ⋯ The bone grafting group was associated with good total active motion scores and low complication rates. The majority of the low velocity gunshot injuries are surgically clean wounds which allow not only early fracture fixation, but also early bone grafting and soft tissue reconstruction. Plate and screw fixation is associated with significantly better functional outcomes than the minimal fixation group.

The aim of this study was to assess the value of direct magnetic resonance (MR) arthrography of the wrist for detecting full-thickness tears of the triangular fibrocartilage complex (TFCC). Twenty-four consecutive patients who had ulnar-sided wrist pain and clinical suspicion of TFCC tear were included in the study. All patients underwent direct MR arthrography and then wrist arthroscopy, and the results of MR arthrography were compared with the arthroscopic findings. ⋯ The overall accuracy of MR arthrography in detecting a full-thickness tear of the TFCC in our study was 79% (19/24). We believe that diagnosis of tears in the TFCC by direct MR arthrography is not entirely satisfactory, although MR arthrography has a high positive predictive value for detecting TFCC tears. Negative results of MR arthrography in patients with clinical suspicion of TFCC tear should be interpreted with caution.
