We biomechanically investigated whether the standard dynamic hip screw (DHS) or the DHS blade achieves better fixation in bone with regard to resistance to pushout, pullout and torsional stability. The experiments were undertaken in an artificial bone substrate in the form of polyurethane foam blocks with predefined mechanical properties. Pushout tests were also repeated in cadaveric femoral he...

Background: Intertrochanteric fractures are one of the most common fractures encountered in our practice. Most of them need operative intervention and union is achieved. As per the literature dynamic hip screw (DHS) is the gold standard for the treatment of these fractures, however problem arises with maintenance of neck shaft angle and proper reduction in unstable intertrochanteric fractures. ...

BACKGROUND Lag screw cut-out failure following fixation of unstable intertrochanteric fractures in osteoporotic bone remains an unsolved challenge. This study tested if resistance to cut-out failure can be improved by using a dual lag screw implant in place of a single lag screw implant. Migration behavior and cut-out resistance of a single and a dual lag screw implant were comparatively evalua...

In this retrospective study, we examine the impact that Background employing a permanent derotation screw (DRS) has on the rate of revision for 2-hole dynamic hip screws (DHS, a.k.a. sliding hip screws), used for internal fixation of intracapsular neck of femur (NOF) fractures. To the best of our knowledge, we are the first to examine the impact of using a derotation screw on DHS revision rate....

Postoperative blood recovery in eighty elderly patients (11 male, 69 female) treated for femoral neck fracture was prospectively studied. Twenty-eight patients underwent hemiarthroplasty for intracapusular fracture and 52 underwent Dynamic Hip Screw fixation for extracapsular femoral neck fracture. The mean blood drainage in the postoperative period and the mean drop in haemoglobin level was hi...

A case of arterial rupture of the profunda femoris arterial branches, following dynamic hip screw (DHS) fixation for an intertrochanteric femoral fracture, is presented. Bleeding is controlled by coil embolization, but, later on, the patient underwent orthopedic material removal due to an infection of a large femoral hematoma.

PURPOSE OF THE STUDY The objective of this study was to establish relative fixation strengths of proximal femoral nail (PFN), dynamic hip screw (DHS), monolateral external fixator (EF), and cannulated screw (CS) in basicervical hip fracture model. MATERIAL AND METHODS The study involved four groups of implanted composite proximal femoral synthetic bones of eight specimens per group; nailing wit...
