[Analysis on risk factors of functional recovery after intramedullary nail fixation for femoral intertrochanteric fractures in elderly patients].

Objective: To investigate the risk factors of functional recovery after intramedullary nail fixation for femoral intertrochanteric fracture in elderly patients, and to propose corresponding measures to promote postoperative hip function recovery.

Methods: From June 2012 to June 2015, 74 patients after intramedullary nail fixation surgery were analyzed, including 33 males and 41 females, with an average age of(75.07±7.

[Complications of percutaneous kyphoplasty non-related with bone leakage in treating osteoporotic thoracolumbar vertebral compression fractures].

Objective: To analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures.

Methods: From October 2008 to October 2012,178 patients with 224 osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty under local anethsia. There were 72 males and 106 females,ranging in age from 58 to 92 years old,with an average of 75.

[Treatment of senile osteoporotic vertebral compression fractures with percutaneous kyphoplasty under local anesthesia].

Objective: To evaluate the clinical outcomes of percutaneous kyphoplasty (PKP) in treating senile osteoporotic vertebral compression fractures under local anesthesia.

Methods: From May 2007 to May 2010,129 patients with osteoporotic vertebral compression fractures were treated with PKP under local anesthesia. There were 47 males and 82 females, ranging in age from 61 to 92 years old,with an average of 73.

[Analysis of perioperative complications of percutaneous kyphoplasty for osteoporotic vertebral compression fracture].

Objective: To analyze the perioperative complications of percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture.

Methods: From June 2009 to December 2011, 63 patients with osteoporotic vertebral compression fracture underwent PKP, there were 18 males and 45 females with an average age of 75.3 years ( ranged, 62 to 91).

[Bernese periacetabular osteotomy for the treatment of severe hip dysplasia].

Objective: To analyze the mid-term clinical and radiographic results obtained with the Bernese periacetabular osteotomy for the treatment of severe hip dysplasia.

Methods: From October 1997 to December 2002 20 hips of 18 patients were classified as having severe acetabular dysplasia (Severin classification Grade IVb). Preoperatively, all patients had hip pain, and sufficient hip joint congruency on functional radiographs.

Acetabular medial wall displacement osteotomy in total hip arthroplasty: a technique to optimize the acetabular reconstruction in acetabular dysplasia.

Twenty-six patients (30 hips) who had acetabular dysplasia were operated on by circumferential acetabular medial wall displacement osteotomy to reconstruct the acetabulum during total hip arthroplasty. All patients had cementless acetabular components implanted. The average acetabular component size was 50 mm (range, 44-56 mm).
