Surgical treatment strategies for proximal femur metastasis have been reported with mixed results. Little is known about risk factor for implant failure except for longer patient survival. Therefore, we determined whether implant survivorship differed among treatment strategies, as well as risk factors for implant failure. We retrospectively reviewed a consecutive 106 patients with proximal femur metastasis treated with prosthesis replacement (n = 38), intramedullary nail (n = 32), and dynamic hip screw (DHS) (n = 36)...

BACKGROUND: Femoral neck fractures are the most common fractures among the elderly. The two operative approaches used for the treatment of AO/OTA 31 intertrochanteric fractures include an intramedullary device (proximal femoral nail [PFN]) or an extramedullary device (sliding/dynamic hip screw [DHS]). The aim of this study was to provide objective evidence of local soft tissue injury by measuring serum creatine phosphokinase (CPK), a biochemical marker, to quantify muscle damage and inflammation in patients treated by the two approaches...

INTRODUCTION: Management of unstable intertrochanteric fractures have posed a unique challenge to orthopaedicians over years. Several surgical techniques and implants have been developed for the same. Fractures of the lateral wall have been considered as the major cause of femoral medialization after fixation by Dynamic Hip Screw (DHS). Studies have shown that supplementation of trochanteric stabilization plate reduces the incidence of femoral medialization. AIM: To assess the radiological union and hip function after fixation of unstable intertrochanteric fractures with DHS and Trochanteric Stabilization Plate (TSP)...

Posterior dislocations of the hip are known to be associated with fractures of the femoral head, neck, shaft, or posterior acetabular wall. However, its association with ipsilateral intertrochanteric fracture has only been anecdotally described in the English literature. We report two such cases managed by open reduction (OR) of the hip and internal fixation (IF) of the intertrochanteric fracture. The first case was a 26-year-old male who was managed by OR of the hip with IF of the intertrochanteric fracture with a dynamic hip screw and had a good functional result at 1-year followup...

To evaluate a new technique of Dynamic hip screw (DHS) fixation without using traction table. From july 2006 to july 2012, 328 patients undergoing DHS fixation using manual traction technique were evaluated in terms of Tip apex distance (TAD), -quality of fracture reduction, operation time, preoperative preparation time. In 97% cases good to moderate reduction could be achieved. The mean TAD was 19.2 millimeters, mean operation time 37 minutes and screw cutout rate was only 0.91%. This technique is easy, reproducible, cheap do not sacrifice reduction alignment, screw position and is extremely beneficial in polytrauma patients where multiple surgeries are to be done...

INTRODUCTION Dynamic hip screw (DHS) fixation for proximal femur fractures is one of the most common procedures in trauma that requires the use of fluoroscopy. Emphasis is often placed on producing the 'perfect picture', which may lead to excessive use of fluoroscopy, without added patient benefit. This study, the largest of its kind, aimed to determine the effect of surgical experience on the amount of radiation exposure from fluoroscopy during DHS fixation. METHODS All hospital admissions for extracapsular proximal femur fractures to our institution between 2007 and 2012 were analysed...

Femoral neck fractures in young patients are rare but of high clinical relevance due to the complexity of risk factors and complications. Early stabilization and accurate reduction are of high priority. Femoral head-preserving stabilization by dynamic hip screws or threefold screw osteosynthesis are the methods of choice. Postoperative results should be closely controlled in every case in order to be able to treat possible complications in time.

INTRODUCTION: The Variable angle Martin Plate (MP) is designed to offer patient-specific adaption for the treatment of intertrochanteric hip fractures. Its proposed benefits include optimization of lag screw placement, plate shaft congruence and reduced risk of failure. Often its use has been criticized as representing a poor reduction of the fracture. The purpose of this study was to assess for a poorer quality of reduction, and compare functional outcomes and mortality, using a MP to that of a fixed angle Dynamic Hip Screw (DHS) in a matched cohort of patients...

A T-handle has been designed to be used for minimally invasive implantation of a dynamic hip screw to repair fractures of the proximal femur. It is capable of being used in two actions: (i) push and hold (while using an angle guide) and (ii) application of torque when using the insertion wrench and lag screw tap. The T-handle can be held in a power or precision grip. It is suitable for either single (sterilised by γ-irradiation) or multiple (sterilised by autoclaving) use. The principles developed here are applicable to handles for a wide range of surgical instruments...
