Prophylactic adjacent-segment vertebroplasty following kyphoplasty for a single osteoporotic vertebral fracture and the risk of adjacent fractures: a retrospective study and clinical experience.

OBJECTIVE This study investigated the benefit of prophylactic vertebroplasty of the adjacent vertebrae in single-segment osteoporotic vertebral body fractures treated with kyphoplasty. METHODS All patients treated with kyphoplasty for osteoporotic single-segment fractures between January 2007 and August 2012 were included in this retrospective study. The patients received either kyphoplasty alone (kyphoplasty group) or kyphoplasty with additional vertebroplasty of the adjacent segment (vertebroplasty group).

10-Year Survival of Acetabular Reinforcement Rings/Cages for Complex Hip Arthroplasty.

Introduction: Acetabular reinforcement rings/ cages (AR) are commonly used for reconstruction of bone defects in complex hip arthroplasty. The aim of this study was to retrospectively investigate the 10-year survival rate of Ganz reinforcement rings and Burch-Schneider cages used in a single institution.

Material And Methods: Between September 1999 and June 2002 all ARs, implanted in one institution, were identified.

Acromioclavicular dislocation Rockwood III-V: results of early versus delayed surgical treatment.

Introduction: The management of acute acromioclavicular joint (ACJ-) injuries especially of type III is still controversial.

Methods: In this retrospective study the results of early ACJ reconstructions immediately after trauma (group early repair, ER) were compared with the results of delayed reconstructions in patients who first got conservative treatment and failed after some time (group delayed repair, DR). Overall, 49 patients were analysed clinically and radiographically with a mean follow-up of 53 months (range 20-92).
