INTRODUCTION: Treatment of moderate to severe slipped capital femoral epiphysis (SCFE) is controversial. Over the last years, 3 institutions in Argentina adopted the modified Dunn procedure for capital realignment in selected cases of SCFE. Our aim in this study was to evaluate the clinical outcome and the rate of complications of patients who had undergone surgical hip dislocation and capital realignment. METHODS: A multicenter retrospective cohort study of patients who received the modified Dunn procedure from January 2009 to 2013 was performed...

BACKGROUND: Stress fractures are the result of cyclic loading of the bone, which gradually becomes damaged. Most often they are treated by rest or plaster cast and, in rare cases, by internal fixation. There is little published data on initial reposition followed by stabilization with the Ilizarov apparatus in such fractures. MATERIAL AND METHODS: Six patients were treated with an external fixator according to the Ilizarov method for a stress fracture of the tibia between 2007 and 2015...

Bone marrow-derived mesenchymal stem cells (BMSCs) have the potential to be used for the treatment of delayed union, nonunion or persistent bone defects in MSC-based cell therapy. However, implantation of BMSCs into the fracture site is confronted with apoptosis on account of harsh conditions and oxidative stress. In the present study, the anti-apoptotic effects of berberine (BBR) on BMSCs subjected to hydrogen peroxide (H2O2) are investigated, and the potential underlying mechanisms are explored. Oxidative injury was induced by exposure to H2O2, and cell viability was assessed using a cell counting kit-8 assay...

Large bone defect creates an urgent need for osteogenic biomaterials. However, bone nonunion and infection are choke points in the therapy of this disease. How to recruit the mesenchymal stem cells to defect sites and increase the cell viability are the critical processes. One effective method was the fabrication of biomimetic silk fibrin/selenium-doped hydroxyapatite (SF/HASe) material, which could create a niche for cell proliferation. So, the aim of the present study was to seek a facile route to prepare this biocomposites and investigate the osteogenic capability...

Clavicle fracture is a common injury due to its subcutaneous and relatively anterior position. Fractures affecting the middle third account for majority of all clavicular fractures. Both non-operative and surgical methods have been described for the management of this injury. However, there is no uniform consensus on the definite choice of treatment. Hence, this study was undertaken to compare conservative approach with primary internal plate fixation in mid-shaft clavicular fractures in terms of subjective outcome, functional outcome, the rates of nonunion and malunion and other local complications...
