BACKGROUND: Femoral neck fractures in young individuals are typically vertical shear fractures. These injuries are difficult to stabilize due to a significant varus displacement force across the hip with weight bearing. The purpose of this study was to evaluate the biomechanical stability offered by the addition of an augmented wire to conventional inverted triangle triple screw fixation for stabilizing vertical shear femoral neck fracture. METHODS: Sixteen medium 4th-generation synthetic composite femurs (Sawbones Pacific Research Laboratories, Vashon, WA) were divided into two groups...

BACKGROUND: Basicervical peritrochanteric fractures are relatively rare, with 1.8% to 7.6% of hip fractures being identified as true basicervical fractures. The compression hip screw traditionally has been considered the "gold standard" for operative fixation of peritrochanteric fractures, with generally good results. The purpose of this study was to report the outcomes of basicervical peritrochanteric fractures of the proximal part of the femur treated with cephalomedullary nailing (CMN)...

Periprosthetic hip fractures are an increasing problem in modern orthopedic and trauma surgery. Many options for the operative treatment are available to the surgeon ranging from modern variable angular systems to standard plates, screws and cerclages. However, there is no gold standard and therefore, the aim of this study was to investigate the biomechanical characteristics of double plating versus a lateral standard plate in a Vancouver B1 fracture model. Ten 4th generation composite femora were used to implant cementless total hip prosthesis and create Vancouver B1 periprosthetic fractures...

BACKGROUND: The number of hip fractures and resulting post-surgical outcome are a major public health concern and the incidence is expected to increase significantly. The acute recovery phase after hip fracture surgery in elder patients is often complicated by severe pain, high morphine consumption, perioperative blood loss with subsequent transfusion and delirium. Postoperative continuous-flow cryocompression therapy is suggested to minimize these complications and to attenuate the inflammatory reaction that the traumatic fracture and subsequent surgical trauma encompass...

OBJECTIVE: This study compared the stabilizing effect of 2 intertrochanteric (IT) fracture fixation devices in a cadaveric hemi-pelvis biomechanical model. METHODS: Eleven pairs of cadaveric osteopenic female hemi-pelves with intact hip joint and capsular ligaments were used. An unstable IT fracture (OTA 31-A2) was created in each specimen and stabilized with a single lag screw device (Gamma 3) or an integrated dual screw (IDS) device (InterTAN). The hemi-pelves were inverted, coupled to a biaxial apparatus and subjected to 13...

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. The situation gets more complex when "cut out" of femoral head screw occurs either alone or in combination with varus collapse when they are treated with DHS...

PURPOSE: Nowadays, the literature shows better results in the treatment of intertrochanteric (AO/OTA 31.A1-A2) hip fractures with dynamic hip screw (DHS) compared with gamma nail (GN). Besides, percutaneous compression plate (PCCP) gives results which are better or similar to those obtained with DHS. But only two reports compare the results between PCCP and GN. The aim of this trial is to compare the outcome of treatment of these fractures with either a PCCP or a GN. METHODS: A retrospective trial with 414 patients over 60 years of age treated in our institution for 6 years, with a minimum follow-up of 1 year, was performed to compare the outcome of a PCCP (240) with a GN (174)...

The dynamic hip-screw (DHS) system is a common implant for fixation of proximal femur fractures. During assembly, it has been recommended to remove the compression screw after initial compression has been obtained; however, related complications had been reported. So far, the role of compression screw in the reconstructed stability of hip fractures as well as the mechanical strength of the DHS system has rarely been mentioned. This study investigated the function of this screw in the DHS system during fracture healing...

BACKGROUND: Hip nailing is frequently used to treat unstable intertrochanteric femoral fractures (ITF) in elderly patients. In this retrospective study, we compared the functional and radiological results, and the complications, of patients treated using proximal femoral nails (PFN) with an integrated, interlocking, compression lag screw, or two separate lag screws, which allow linear compression at the fracture site. METHODS: A total of one hundred and eighteen patients were operated on for AO/OTA 31-A2 ITF between May 2010 and April 2012, and eighty-two of these patients, for whom sufficient follow-up data and documentation were available, were included into the study...

The study evaluated the incidence of and complications associated with the use of an intramedullary nail vs open reduction and internal fixation (ORIF) with a sliding compression hip screw and plate in treating intertrochanteric fractures. The authors hypothesized that the biomechanically stronger and less invasive intramedullary nail would have superior results and fewer complications compared with ORIF. Patients followed for up to 1 year postoperatively were identified from the 5% nationwide sample of Medicare administrative claims data (1998-2007) using the corresponding International Classification of Diseases, 9th revision, Clinical Modification, codes 820...
