A preliminary study of Acoustic Emission during orthopaedic screw fixation was performed using polyurethane foam as the bone-simulating material. Three sets of screws, a Dynamic Hip Screw, a small fragment screw and a large fragment screw were investigated, monitoring acoustic emission activity during the screw tightening. Some specimens were overtightened on purpose to investigate the possibil...

Introduction Proximal femur is the common site for localization of benign bone lesions, and the diagnosis is often delayed and potentially challenging due to their atypical presentations. Early diagnosis is difficult as intra-articular lesions often present with clinical and radiological features of inflammatory synovitis in the joint. Case Report Two patients of intra-articular osteoid osteo...

Kerala Journal of Orthopaedics 2012;25:6-13 Introduction Surgical stabil isation of the intertrochanteric fracture is the optimal treatment today, except in patients with medical problems in whom surgery is contraindicated (1). The goal of surgery is to provide fracture stability to allow early mobilisation and some weightbearing. The introduction of the Dynamic Hip Screw was a quantum leap in ...

OBJECTIVE To analyze the in vitro mechanical strength of the DHS-AF(®). METHODS We evaluated the in vitro resistance of a sliding bolt modified by the addition of a connector system, DHS-AF(®). RESULTS The changes performed by the authors allow the exchange by the surgeon of the sliding bolt without the need to remove the plate and disassemble the entire device to reposition it properly. We...

OBJECTIVE To analyze the short-term results from treating unstable intertrochanteric fractures with Dynamic Hip Screws (DHS), using a minimally invasive route, focusing on the functional aspects and complication and mortality rates of the method. METHODS This was a prospective longitudinal study on 140 patients who underwent fixation of transtrochanteric fractures with the DHS system with a l...

INTRODUCTION We report the case of an unusual combination of concomitant subcapital and intertrochanteric fractures of the hip in a patient after a motorcycle accident. To the best of our knowledge, there is no previous report in the literature of these conditions as a result of high energy trauma or of the treatment used. CASE PRESENTATION A 36-year-old Caucasian man was admitted with this r...
