[Arthroscopic Bankart repair combined with Reimplissage for the treatment of recurrent anterior dislocation of shoulder in adults with Hill-Sachs defect].

Objective: To investigate the method and clinical effects of the treatment of recurrent anterior dislocation of shoulder with Hill-Sachs injury by arthroscopic Bankart repair and Remplissage.

Methods: From March 2016 to March 2019, 106 patients with recurrent anterior dislocation of shoulder with glenoid bone defect less than 20% underwent arthroscopic Bankart repair, including 76 males and 30 females, aged from 18 to 45 (27.3±8.

Investigation on the role of VEGF gene polymorphisms in the risk of osteosarcoma.

Objective: The VEGF in low oxygen conditions are reported to prolong the survival of malignant cell, and thus this gene has a critical role in tumor growth and invasion as well as development of malignant tumor. We aimed to assess the association between the six common SNPs and the risk of osteosarcoma, and their association with environmental factors.

Methods: 176 subjects with osteosarcoma and 176 gender- and sex-matched healthy control individuals were enrolled into our study.

[Comparative analysis of modified Dewar method versus arthroscopic double Endobutton fixation technique for the treatment of acute acromioclavicular joint dislocation].

Objective: To compare the clinical outcomes of modified Dewar method versus arthroscopic double Endobutton fixation technique for the treatment of acute acromioclavicular joint dislocation (Rockwood types III-V).

Methods: All cases with acute acromioclavicular joint dislocation (Rockwood types III-V) were treated at our department from October 1997 to October 2009. Among them, 28 cases undergoing modified Dewar method were followed up.
