BACKGROUND: In treatment of unstable trochanteric fractures dynamic hip screw and Medoff sliding plate devices are designed to allow secondary fracture impaction, whereas intramedullary nails aim to maintain fracture alignment. Different treatment protocols are used by two similar Swedish regional emergency care hospitals. Dynamic hip screw is used for fractures considered as stable within the respective treatment protocol, whereas one treatment protocol (Medoff sliding plate/dynamic hip screw) uses biaxial Medoff sliding plate for unstable pertrochanteric fractures and uniaxial Medoff sliding plate for subtrochanteric fractures, the second (intramedullary nail/dynamic hip screw) uses intramedullary nail for subtrochanteric fractures and for pertrochanteric fractures with intertrochanteric comminution or subtrochanteric extension...

BACKGROUND: Posteromedial and greater trochanteric fragments are a major cause of telescoping and medialization of the femoral shaft in an unstable intertrochanteric fracture. This leads to significant limb shortening, fracture collapse in varus position and implant failure, which can be prevented by trochanteric wiring in addition to dynamic hip screw (DHS) fixation. The purpose of our study is to assess the outcomes of DHS augmented with trochanteric wiring in unstable type A2 intertrochanteric fractures...

INTRODUCTION: Proximal Femoral Nailing (PFN) in Intertrochanteric Fractures (IF) is becoming the choice of implant due to better biomechanics and prevention of varus collapse associated with Dynamic Hip Screw (DHS). Technical difficulties and implant related complications are yet to be addressed. AIM: To understand the technical difficulties involved in PFN and role of provisional fixation of fracture by Steinmann-pin. MATERIALS AND METHODS: In this study, 55 patients presented to a tertiary trauma center in India with trochanteric fractures from April 2010 to March 2012 were included and treated with PFN...

INTRODUCTION: Posterior comminution of the femoral neck fracture is a major cause of delayed and non-union owing to the loss of the buttressing effect against the posterior rotation. When a femoral neck fracture with posterior comminution is anatomically reduced, only the anterior portions of the femoral neck fracture surfaces are brought into contact leaving a posterior defect. The purpose of this study was to evaluate the use of fibular strut grafting and dynamic hip screw (DHS) for fresh femoral neck fractures with posterior comminution in young patient less than 50 years...

BACKGROUND: Surgical site infection in orthopaedic implants is a major problem, causing long hospital stay, cost to the patient and is a burden on health care facilities. It increases rate of nonunion, osteomyelitis, implant failure, sepsis, multiorgan dysfunction and even death. Surgical site infection is defined as pain, erythema, swelling and discharge from wound site. Surgical site infection in orthopaedic implants is more challenging to the treating orthopaedic surgeon as the causative organism is protected by a biofilm over the implant's surface...

INTRODUCTION: Management of Pauwels type-3 vertical femoral neck fractures has been a challenging clinical problem as they experience high shear forces and thus a greater risk of treatment failure. There is no apparent consensus on the optimal implant type for these injuries. We developed a modified dynamic hip screw (DHS), which was designed to a cage in the lag screw, loaded with autologous bone graft for the treatment of Pauwels type-3 vertical femoral neck fractures. METHODS: Between February 2010 and January 2012, 17 consecutive patients with Pauwels type-3 vertical femoral neck fractures were treated with the modified DHS loaded with autologous bone graft...

INTRODUCTION: Fractures of the Intertrochanteric (IT) region are some of the most common fractures encountered by an orthopedic surgeon in his lifetime. With increase in life expectancy, the incidence of these fractures is also increasing. By 2040, the incidence of these fractures is expected to double. Unstable IT fractures are a major cause of concern in the elderly due to the associated increase in morbidity and mortality. AIM: The purpose of this study was to compare the intraoperative and postoperative parameters using the Dynamic Hip Screw (DHS), the Cemented Bipolar Hemiarthroplasty (BH) and the Proximal Femoral Nail (PFN) for the management of unstable IT fractures...
