Single versus double row suture anchor fixation for greater tuberosity fractures – a biomechanical study
BACKGROUND Fractures of the humeral greater tuberosity (GT) are a frequent injury progressively treated with arthroscopic suture anchor repair. Yet, no biomechanical study has been performed comparing fixation strength of arthroscopic single- (SR) vs. double row (DR) fixation. METHODS Standardized fractures of the greater tuberosity were created in 12 fresh frozen proximal humeri. After rando...
متن کاملBiomechanical evaluation of subpectoral biceps tenodesis: dual suture anchor versus interference screw fixation.
BACKGROUND Subpectoral biceps tenodesis has been reliably used to treat a variety of biceps tendon pathologies. Interference screws have been shown to have superior biomechanical properties compared to suture anchors; although, only single anchor constructs have been evaluated in the subpectoral region. The purpose of this study was to compare interference screw fixation with a suture anchor co...
متن کاملIsolated fractures of the greater tuberosity of the proximal humerus
BACKGROUND AND PURPOSE The diagnosis and treatment of isolated greater tuberosity fractures of the proximal humerus is not clear-cut. We retrospectively assessed the clinical and radiographic outcome of isolated greater tuberosity fractures. PATIENTS AND METHODS 30 patients (mean age 58 (26-85) years, 19 women) with 30 closed isolated greater tuberosity fractures were reassessed after an aver...
متن کاملCannulated versus non-cannulated cancellous screw fixation for femoral neck fractures: a synthetic bone biomechanical study
Purpose. To compare the compressive strength of cannulated versus non-cannulated cancellous screws for undisplaced femoral neck fractures in synthetic bones. Methods. 18 synthetic proximal femurs simulating an AO B1 valgus impacted femoral neck fracture in osteoporotic bone were used. The fracture angles were between 55o and 63o (Pauwels grade 2). Fixation was made using 6.5-mm non-cannulated s...
متن کاملLong-term Results, Functional Outcomes and Complications after Open Reduction and Internal Fixation of Neglected and Displaced Greater Tuberosity of Humerus Fractures
Background: Humerus fractures include 5% to 8% of total fractures. Non-union and delayed union of GT (GT) fractures is uncommon; however they present a challenge to the orthopedic surgeons. Significant controversy surrounds optimal treatment of neglected fractures. The purpose of this article was to perform a comparative study to evaluate the outcomes of open reduction and internal fixatio...
