Although acute vascular injury is a common complication in children with severely displaced supracondylar humeral fractures, the management of patients with a pink pulseless hand still remains controversial. Between 1994 and 2006, 66 children with displaced supracondylar fractures of the humerus were treated. Five patients had an absence of the radial pulse with an otherwise well perfused hand. ⋯ Thrombectomy was performed, which led to the restoration of a palpable radial pulse. In one patient with open fracture, brachial artery contusion and spasm were found, and treated by removal of adventitia. Surgical exploration for the restoration of brachial artery patency should be performed, even in the presence of viable pink hand after an attempt at closed reduction.

Review Meta Analysis
Closed suction surgical wound drainage after hip fracture surgery: a systematic review and meta-analysis of randomised controlled trials.
There is still debate over the use of drains following hip fracture surgery. We have performed a systematic review and meta-analysis of the literature for randomised trials that related to the use of closed suction drains following hip fracture surgery. ⋯ All other outcomes reported failed to show any benefit from the use of drains. Further randomised trials are required and until they have been undertaken the efficacy of closed surgical drainage systems in hip fracture surgery is unknown.

The aim of this prospective study was to measure bone density changes and to assess adaptive bone remodelling after uncemented total hip arthroplasty with a taper-design femoral component using quantitative computer-tomography-assisted osteodensitometry. This method is able to differentiate cortical and cancellous bone structures. Twenty-seven consecutive patients (29 hips) with degenerative joint disease were enrolled in the study. ⋯ We observed small changes of cortical bone density in the diaphyseal regions; in contrast, cancellous bone density increased (range 6% to 27%) in the diaphyseal regions. Overall, a trend of bone density recovery was observed throughout the follow-up period. Periprosthetic bone density changes at the 2-year follow-up are suggestive of stable osteointegration with proximal femoral diaphysis load transfer and moderate metaphyseal stress-shielding.

Comparative Study
Surgical treatment of midclavicular fractures: a prospective comparison of Knowles pinning and plate fixation.
Although several surgical techniques for midclavicular fractures have been reported, Knowles pinning has rarely been compared with plating. The purpose of this study is to compare the clinical results of these two alternative techniques. There were 88 patients with midclavicular fractures surgically treated with either a Knowles pin or a plate. ⋯ Plating has a significantly longer operation time, larger wound incision, higher pain level, more analgesic use, more complications and more symptomatic hardware (all p value<0.05). The shoulder score, union rate and healing time are not significantly different between the two groups (all p values>0.2). In conclusion, if the surgery of mid-third clavicular fractures is indicated, fixation with a Knowles pin has more advantages than plate fixation.
