[Case-control study on shoulder pain caused by hook palte for the treatment of acromioclavicular joint dislocation].

Objective: To explore causes of shoulder pain and propose prevention measures in treating acromioclavicular joint dislocation.

Methods: From January 2005 to January 2013, 86 patients with acromioclavicular joint dislocation (Tossy III) were treated with hook plate fixation, and were divided into two groups. Bsaed on recovery of shoulder function mostly, the patients who suffered from rest pain, motion pain were named as shoulder pain group, while the patients without pain were named as painless group.

Percent free prostate-specific antigen is effective to predict prostate biopsy outcome in Chinese men with prostate-specific antigen between 10.1 and 20.0 ng ml(-1).

Percent free prostatic-specific antigen (%fPSA) has been introduced as a tool to avoid unnecessary biopsies in patients with a serum PSA level of 4.0-10.0 ng ml-1 , however, it remains controversial whether %fPSA is effective in PSA range of 10.

Unilateral or bilateral percutaneous vertebroplasty for acute osteoporotic vertebral fracture: a prospective study.

Background: Percutaneous vertebroplasty (PVP) has been demonstrated to be effective in the treatment of acute osteoporotic vertebral fracture (AOVF). However, the matter of which surgical approach should be selected remains controversial. This research aims to compare the clinical results of unilateral and bilateral PVP for AOVF.

Locking internal fixator with minimally invasive plate osteosynthesis for the proximal and distal tibial fractures.

Objective: To investigate the efficacy of the locking internal fixator (LIF), which includes the locking compression plate (LCP) and the less invasive stable system (LISS), in the proximal and distal tibial fractures.

Methods: We did a retrospective study on a total of 98 patients with either proximal or distal tibial fractures from January 2003 to January 2007, who had received the operation with LIF by the minimally invasive plate osteosynthesis (MIPO) technique. The data consisted of 43 proximal tibial fractures (type AO41C3) and 55 distal tibial fractures (type AO43C3).

[Strategy and analysis of early management on ninety multiple trauma patients].

Objective: To explore the therapeutical effects through investigating the results of multiple traumas treated by means of damage control surgery (DCS) or early total care (ETC).

Methods: The clinical data of 90 patients with severe multiple traumas admitted from June 2001 to June 2007 were analyzed retrospectively. Forty-five patients were classified to the DCS group, 45 patients to the ETC group as a control.

[Combination of volar buttress plate with external fixator for the distal radial fractures of type C3 caused by high-energy injuries].

Objective: To preliminarily explore the effect of combination of volar buttress plate with external fixator for the distal radial fractures of type C3 caused by high-energy injuries.

Methods: From January 2001 to June 2007, 13 patients with distal radial fracture of type C3, 9 males and 4 females aged from 26 to 47 (average 37 years), were treated with volar buttress plate combined with external fixator plus the techniques of K-wires and bone grafting as necessary, whose effects were evaluated preliminarily through comparing the volar tilt, radial inclination, radial shortening and wrist function.

Results: Followed up from 7 to 29 months (average 18 months), the volar tilt, radial inclination, radial shortening and wrist function of all patients recovered remarkably.
