A retrospective analysis of 140 patients with giant cell tumor in the extremity: a multicenter study based on four hospitals in South China.

Background: Update reports are rarely available regarding the bone giant cell tumors (GCTs) in the extremity in Chinese people. The aim of this study was to review the epidemiological characteristics of bone GCT in the extremity based on the clinical data from four hospitals in South China.

Methods: We searched medical electronic records from January 2001 to December 2011 in four hospitals in South China to identify patients with definite diagnosis of extremity GCT.

Should displaced midshaft clavicular fractures be treated surgically? A meta-analysis based on current evidence.

Purpose: This study was designed to compare clinical effectiveness of operative with nonoperative treatment for displaced midshaft clavicular fractures (DMCF).

Methods: We systematically searched electronic databases (MEDILINE, EMBASE, CLINICAL, OVID, BIOSIS and Cochrane registry of controlled clinical trials) to identify randomized controlled trials (RCTs) in which operative treatment was compared with nonoperative treatment for DMCF from 1980 to 2012. The methodologic quality of trials was assessed.

[Finite element analysis of the initial stability of subtalar arthrodesis with double-screw fixation].

Objective: To assess the optimal configuration of double-screw fixation for subtalar arthrodesis using finite element analysis.

Methods: Three-dimensional finite element double-screw models of subtalar arthrodesis were reconstructed using Mimics 13.0, Geomagic 10.

Surgical versus nonsurgical treatment of displaced intra-articular calcaneal fracture: a meta-analysis of current evidence base.

Purpose: Controversy still surrounds the optimal treatment for patients with displaced intra-articular calcaneal fractures (DIACF). An up-to-date meta-analysis was performed to evaluate clinical effectiveness of surgical treatment for DIACF compared with nonsurgical treatment.

Methods: We systematically searched four electronic databases (Medline, BIOSIS, Cochrane library and Google Scholar) to identify randomised controlled trials (RCTs) and clinical controlled trials (CCTs) in which surgical treatment was compared with nonsurgical treatment of DIACF from 1980 to 2011.
