Effect of elbow flexion angles on stress distribution of the proximal ulnar and radius bones under a vertical load: measurement using resistance strain gauges.

Objectives: This study aimed to explore the surface stress at the proximal ends of the ulna and radius at different elbow flexion angles using the resistance strain method.

Methods: Eight fresh adult cadaveric elbows were tested. The forearms were fixed in a neutral position.

Revision hip arthroplasty as a treatment of Vancouver B3 periprosthetic femoral fractures without bone grafting.

Background: It is conventionally considered that bone grafting is mandatory for Vancouver B3 periprosthetic femoral fractures (PFF) although few clinical studies have challenged the concept previously. The aim of the current study was to investigate the radiographic and functional results of Vancouver B3 PFF treated by revision total hip or hemiarthroplasty (HA) in combination with appropriate internal fixation without bone grafting.

Materials And Methods: 12 patients with Vancouver B3 PFF were treated by revision THA/HA without bone grafting between March 2004 and May 2008.

Clinical value of the Ottawa ankle rules for diagnosis of fractures in acute ankle injuries.

Background: The Ottawa ankle rules (OAR) are clinical decision guidelines used to identify whether patients with ankle injuries need to undergo radiography. The OAR have been proven that their application reduces unnecessary radiography. They have nearly perfect sensitivity for identifying clinically significant ankle fractures.

Surgical approach for high-energy posterior tibial plateau fractures.

Background: High-energy fractures of posterior tibial plateau always need surgical treatment. Generally, posterior fragments of these fractures could not be exposed and reduced well in conventional anterior approaches. Although a posterolateral/posteromedial approach to manage posterior tibial plateau fractures can achieve satisfactory results, there are few presentations concerning the treatment of these high-energy injuries based on posterior approaches combined with anterior approach if necessary.
