OBJECTIVES 1) To introduce a computed tomography-based "three-column fixation" concept; and 2) to evaluate clinical outcomes (by using a column-specific fixation technique) for complex tibial plateau fractures (Schatzker classification Types V and VI). DESIGN Prospective cohort study. SETTING Level 1 trauma center. PATIENTS Twenty-nine cases of(More)
Transforming growth factor (TGF)-beta1 can cause fibrosis diseases by enhancing production of collagen. However, the intracellular signaling mechanism for TGF-beta1 stimulation of this process has not been fully elucidated. The present study focused on this mechanism and the cross-talk between the MAPK and Smad pathways. Extracellular signal-regulated(More)
Results of two methods, conventional open reduction–internal plating and minimally invasive plating osteosynthesis (MIPO), in the treatment of mid-distal humeral shaft fractures were compared. Thirty-three patients were retrospectively analysed and divided into two groups. Group A (n = 17) patients were treated by MIPO and group B (n = 16) by conventional(More)
BACKGROUND Titanium elastic nails (TENs) are commonly used to repair displaced midshaft clavicular fractures. Although several clinical studies have shown that the use of TENs is more effective and less invasive than traditional plate fixation, high rates of complications associated with TENs have been reported. This retrospective study compared the use of(More)
The treatment for humeral shaft fracture is still controversial, especially for complex fractures. The purpose of this study was to evaluate the clinical and radiographic outcomes of treating complex humeral shaft fractures by using locking compression plate with minimally invasive technique. A total of 21 patients with 21 acute complex humeral shaft(More)
Extracorporeal shock wave treatment appears to be effective in patients with avascular necrosis of the femoral head. However, the pathway of biological events whereby this is accomplished has not been fully elucidated. The purpose of this study was to investigate the effect of extracorporeal shock waves on vascular endothelial growth factor (VEGF)(More)
We evaluated the healing rate, complications, and functional outcomes in 32 adult patients with very short metaphyseal fragments in fractures of the distal tibia treated with a polyaxial locking system. The average distance from the distal extent of the fracture to the tibial plafond was 11 mm. All fractures healed and the average time to union was 14(More)
This retrospective study compared the results after anterior cruciate ligament (ACL) reconstruction using a four-strand hamstring tendon graft (4SHG) versus Ligament Advanced Reinforcement System (LARS) artificial ligament in 60 patients between January 2003 and July 2004 with a minimum four-year follow-up. The KT-1000 examination, the International Knee(More)
The present investigation is a prospective study comparing the use of locked plates and classic double plates for the repair of bicondylar tibial plateau fractures. Eighty-four patients with bicondylar tibial plateau fractures were treated with plate fixation by either a locked plate (Less Invasive Stabilization System, LISS) or classic double plates (DP).(More)
BACKGROUND The purpose of our study is to introduce a new Three-Column Classification for tibial plateau fractures and evaluate its reproducibility and reliability. METHODS From December 2004 to December 2006, 278 consecutive patients with tibial plateau fractures were treated operatively at the Department of Orthopedics and Trauma III in Shanghai Sixth(More)
