To our knowledge, pseudoaneurysms of the posterior tibial artery after tibial plate removal are a rare phenomenon. We report a case of a 18-year-old male patient who had pseudoaneurysm of posterior tibial artery following plate removal.

A Comparison of Hand Pain and Hand Function after Z-plasty Reconstruction of the Transverse Carpal Ligament with Traditional Median Neurolysis in Carpal Tunnel Syndrome.

Background: Carpal tunnel syndrome is the most common focal mono-neuropathy. A study was designed to compare the effects of traditional open carpal tunnel release with median neurolysis and Z-plasty reconstruction of the transverse carpal ligament on post-operative hand pain and hand function in patients with idiopathic carpal tunnel syndrome.

Methods: Fifty-two patients with idiopathic carpal tunnel syndrome entered the study.

Comparison of surgical complications of intertrochanteric hip fractures between non-osteoporotic and osteoporotic patients.

Objective: To determine the role of bone quality in post-treatment complications among patients of intertrochanteric fracture.

Methods: The cross-sectional descriptive study was done on 61 patients who presented with intertrochanteric hip fractures to two affiliated hospitals of Mazandaran University of Medical Science, Sari, Iran between February 2009 and December 2010. All the patients went through open reduction and internal fixation using 4-hole dynamic hip screw.

Anterior shoulder dislocation and ipsilateral humeral shaft fracture.

Simultaneous dislocation of shoulder and humeral shaft fracture is a rare injury, and there is no clear protocol for its treatment. Herein we present a case of a 15-year-old boy, who suffered from a job-related accident and sustained fracture of humeral shaft associated with ipsilateral anterior shoulder dislocation and fracture of greater tuberosity 15 years ago. He received closed reduction of both injuries and coaptation plaster splint for four weeks, followed by Sarmiento splint at that time.
