OBJECTIVE The objective of this study was to compare treatment results and complication rates between lateral and posterior approaches in surgical treatment of extra-articular distal humeral shaft fractures. MATERIAL AND METHODS Between June 2008 and May 2012, a total of 68 patients with extra-articular distal humeral shaft fractures were treated by(More)
Calcium phosphate cement (CPC) that can be injected to form a scaffold in situ has promise for the repair of bone defects. However, its low-strength limits the CPC to non-stress-bearing repairs. Fibrin glue (FG) with good sticking property and biocompatibility is possible used to reinforce the CPC. The objective of this study was to investigate the effects(More)
OBJECTIVE To investigate the surgical treatment effectiveness of acetabular transverse and posterior wall fractures by Kocher-Langenbeck approach. METHODS Between January 2002 and February 2009, 17 patients with acetabular transverse and posterior wall fractures were treated with Kocher-Langenbeck approach and fracture reduction and fixation. There were(More)
OBJECTIVE To report the clinical results of hemiprosthesis for unstable intertrochanteric fractures in elderly patients. METHODS 86 cases (male 35 and females 51) of unstable intertrochanteric fractures in elderly patients were treated with hemiprosthesis arthroplasty in our hospital. The average age was 87 years old (range from 80 to 98 years old).(More)
OBJECTIVE To investigate the characteristics of patients with crush injury in Wenchuan earthquake and the corresponding operational methods. METHODS From May 12th 2008 to June 18th 2008, 202 patients with crush injury of soft tissue were treated, including 110 males and 92 females. Twenty-five patients aged 19 months to 16 years, 129 patients aged 17-60(More)
OBJECTIVE To evaluate the effects of tibial shaft fractures treatment with plate-screw or intramedullary interlocking nail. METHODS Thirty-five fractures were treated with intramedullary interlocking nail. Tape A, B and C were 11, 18 and 6 cases respectively according to AO classification. Forty-five fractures were treated with plate-screw system. Type(More)
OBJECTIVE To compare the effectiveness of internal fixation, hemiarthroplasty, and total hip arthroplasty in the treatment of displaced femoral neck fractures in elderly patients so as to provide the evidence for the selection of therapeutic methods. METHODS Between May 2005 and April 2008, 108 elderly patients with displaced femoral neck fractures were(More)
A novel biped robot and its control strategy are presented. The robot has cylindrical bar distributing in lateral plane as it's feet, which can acts as a pivot when walking. Then the robot can realize completely dynamic walking. The hybrid dynamic model is developed and gait is planned using strategy of time-invariant. By the finite-time nonlinear(More)
BACKGROUND Among the various treatments of neurologically involved unstable thoracolumbar burst fractures, the combination of anterior and posterior instrumentation provides the most stable reconstruction. However, the use of both approaches on a trauma patient may increase the morbidity. This study is a retrospective matched cohort study to evaluate the(More)
A novel stability criterion for underactuated biped robot is presented. The underactuated biped robot contacts ground with points and has not feet while walking and running. A stability definition of biped robot is given. The Loss Balance Degree(LBD) is proposed as a novel stability criterion for underactuated biped robot according to the stability(More)
