Objective: To explore clinical outcomes and advantages of anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal tuberculosis.
Methods: From February 2010 to February 2014, totally 82 patients with lumbar spinal tuberculosis were treated by posterior individual fixation with small-incision focus debridement,including 50 males and 32 females with an average of 50.5 years old. All patients were divided into two groups according to different procedures. Forty-nine patients in group A were treated with anterior small-incision focus debridement with posterior internal fixation through muscle spa ring at stage I ; and 33 patients in group B were treated with focus debridement with posterior internal fixation by extraperitoneal approach at stage I . Postoperative mechanical ventilation time, preoperative and postoperative Cobb angle, visual analogue scale (VAS), erythrocyte sedimentation rate (ESR) and Frankel grading were observed and compared. Postoperative complications, stability of internal fixation and bone union were compared.
Results: All patients were followed-up from 15 to 36 months with an average of 23.7 months. Psoas abscess of three patients in group A and 1 patient in group B on the opposite side increased and were healed by the secondary apocenosis. The other 78 cases were healed at stage I, and no sinus tract formation, incisional hernia, leakage of cerebrospinal and occurrence of spinal tuberculosis were occurred. Fracture healing time ranged from 3 to 7 months with an average of 4.6 months. Postoperative mechanical ventilation time and VAS score in group A was better than group B. There were no statistical differences in Cobb angle, ESR and Frankel grading at the final following-up between two groups.
Conclusion: Anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal according to degree of damage is a safe and effective method.

Purpose: Diabetes mellitus (DM) is a well-established risk factor for postoperative complications. Distal radius fractures (DRFs) are a common orthopedic injury and often require open reduction and internal fixation (ORIF). The rise of ORIF utilization warrants investigation into factors that may expose patients to postoperative complications following DRF ORIF.

Objectives: This study aims to analyze the biomechanics of three kinds of rigid internal fixation methods for condylar head fractures.
Methods: A three dimensional finite element model of the normal mandible was constructed. It was then used to prepare condylar head fracture finite element model and three kinds of rigid internal fixation finite element model (unilateral tension screw, bilateral tension screw, tension screw+titanium plate).

Locking plates have a rapidly growing process especially in the past decades and results are satisfactory especially in the osteoporotic bones compared to non-locking compression plates. There are many forms of failure in the fracture fixation of locking plates, and screw pull-out is one of the main failure reasons. In this study, we aim to investigate pull-out failure in locking plates using locking spongious screws.

To investigate the feasibility and clinical efficacy of a novel approach to managing the incisions used to treat tibial plateau fractures (TPFs) with soft tissue swelling. We retrospectively enrolled 64 patients with TPFs who underwent surgery at the Second Hospital of Shandong University. Patients were divided into two groups: Group A (n = 32) underwent early surgery with the novel incision management technique, and Group B (n = 32) underwent conventional surgery after swelling reduction.
