OBJECTIVE To study the outcome of subtrochanteric hip fractures treated with proximal lateral femur locking plate. METHOD We retrospectively reviewed the clinical results of 48 cases of femoral subtrochanteric fractures treated with proximal lateral femur locking plates from January 2008 to May 2010. The progress of fracture healing, as well as the occurrence of complications, was recorded. T...

BACKGROUND Several factors are known to influence osseous union of femoral neck fractures. Numerous clinical studies have reported different results, hence with different recommendations regarding treatment of Pauwels III fractures: femoral neck fractures with a more vertically oriented fracture line. The current study aimed to analyze biomechanically whether this fracture poses a higher risk o...

Previous studies have shown that impacted mandibular third molars (M3s) increase the risk of mandibular angle fractures and decrease the risk of mandibular condylar fractures. This study attempted to verify these relationships and identify the influence of mechanism and cause of injury. The incidence of fractures was compared in 700 patients with and without impacted M3s. The results showed tha...

Osteochondral fracture of lateral femoral condyle can result from support and other twisting injuries of the knee. Arthroscopy is a better diagnostic and therapeutic tool as standard radiographs can mislead regarding the size and location of the fragment. If fragment is large and displaced, arthrotomy may become necessary. We present a case of large osteochondral fracture of lateral femoral con...

It is unclear whether there is a limit to the amount of distal bone required to support fixation of supracondylar periprosthetic femoral fractures. This retrospective multicentre study evaluated lateral locked plating of periprosthetic supracondylar femoral fractures and compared the results according to extension of the fracture distal with the proximal border of the femoral prosthetic compone...

Rotational alignment of the femoral component in total knee arthroplasty (TKA) is important for patellar tracking and ligament balance. Preoperative planning based on radiography might have a potential risk for over-rotation because these X-ray based measurements can not detect asymmetric cartilage wear on posterior condyle. The purpose of this study is to evaluate the effect of the posterior c...

PURPOSE To evaluate the effect of femoral condylar offset and posterior tibial slope on maximal flexion angle of the knee in posterior cruciate ligament (PCL)-sacrificing total knee arthroplasty (TKA, Medial-Pivot Knee System). MATERIALS AND METHODS Forty-five knees in 35 patients who could be followed up more than 1 year after PCL-sacrificing TKA were evaluated retrospectively. We measured a...

BACKGROUND The treatment of the condylar fractures is difficult. Factors that result in the fractures are complex. The objective of this morphometric study was to investigate the relationship between condylar fracture patterns and condylar morphological characteristics. METHODS We conducted a retrospective analysis of 107 patients admitted to the West China Hospital of Stomatology for bilater...

w d f ractures of the condylar head are generally treated conseratively because exposure and fixation are difficult without amaging the facial nerve. Conservative treatment is also recmmended for children or for patients whose condylar head s in several fragments.1 The conservative approach requires ong-term treatment, whereas open surgery can provide early ecovery of occlusion and movement of ...
