INTRODUCTION: Non-union following interlocking nailing is a troubling complication in treatment of shaft femur fractures. There is no clear consensus on the treatment of this problem. This research was undertaken to study the role of augmentation plating combined with exchange nailing in such cases. PATIENTS AND METHODS: A prospective clinical study was undertaken from January 2010 to December 2015. Patients with aseptic femoral shaft non-union, with or without implant failure following intramedullary nailing were included in the study...

The intraoperatively rotational control of femoral shaft fractures treated with a closed intramedullary interlocking nailing is a challenging problem. A novel surgical technique that includes respective insertions of guidewires into the proximal and distal femur under the guidance of a 2-dimensional fluoroscopy-based navigation system and the measurements of the intersection angle subtended by the proximal and distal guidewires with the smartphone positional software has been designed to provide intraoperatively quantitative parameters of femoral rotation deformation...

Interlocked intramedullary nailing is the treatment of choice for femoral shaft fractures. However, distal locking is a technically challenging part of the procedure that can result in distal femoral malrotation and high radiation exposure. We have tested a robotic procedure for robotic distal locking based on the computation of a drilling trajectory on two calibrated fluoroscopic images. Twenty distal holes were attempted in ten cadaveric femur specimens. Successful screw hole drilling was achieved at the first attempt in each of the ten specimens (20 drill holes in total)...

BACKGROUND: To determine if the AAOS clinical practice guidelines (CPG) for the treatment of pediatric femoral shaft fractures (2009) changed treatment, we analyzed pediatric femoral shaft fractures at 4 high-volume, geographically separated, level-1 pediatric trauma centers over a 10-year period (2004 to 2013). METHODS: Consecutive series of pediatric femoral shaft fractures (ages, birth to 18 y) treated at the 4 centers were reviewed. Treatment methods were analyzed by age and treatment method for each center and in aggregate...

Slipped capital femoral epiphysis (SCFE) is an adolescent disease that leads to retroversion of the femoral neck and shaft, relative to the head. Observing that patients with SCFE must walk with an outward foot progression angle and externally rotate the leg in order to flex the hip, we have been performing a femoral shaft rotational osteotomy wherein we rotate the lower femur 45° inward, relative to the upper femur. By correcting retroversion, our goal is to improve functional hip and knee motion, thereby mitigating the effects of SCFE impingement...

PURPOSE: New research is focusing on the use of autologous growth factors to increase the effect of bone fracture healing while decreasing the amount of healing time for the patient. Platelets have been demonstrated to be the natural storage vessel for several growth factors and cytokines that promote blood coagulation, tissue repair, and the process of bone mineralization. The present study aims to evaluate the role of platelet-rich plasma (PRP) in healing of acute femoral shaft fractures radiologically...

INTRODUCTION: Biomechanically proximal femoral nail (PFN) is a better choice of implant, still it is associated with screw breakage, cut out of screw through femoral head, Z effect, reverse Z effect, and lateral migration of screws. The purpose of this study is to evaluate the results of augmented PFN in terms of prevention of postoperative complications and failure rates in unstable trochanteric fractures. MATERIAL AND METHODS: We carried out a prospective study of 82 cases with unstable trochanteric femoral fractures from April 2010 to December 2015...

INTRODUCTION: Removal of symptomatic implants is a common procedure performed by orthopaedic trauma surgeons. No guidance is available regarding which factors contribute to the likelihood of an implant becoming symptomatic. Our objective was to determine whether radiographic parameters associated with distal interlocks in retrograde femoral nails are associated with the rate of symptomatic screw removal. PATIENTS AND METHODS: We conducted a retrospective review at a Level I trauma center...

Femoral and tibial shaft fractures are common injuries in the United States. Since their introduction, reamed intramedullary nails have become the treatment of choice for most of these fractures. However, delayed union and nonunion can complicate treatment in up to 10% of patients. Removal of interlocking screws, or dynamization, can promote fracture healing in cases of delayed union or nonunion. The efficacy of nail dynamization has been reported to range from 19% to 82%. This study was conducted to evaluate the efficacy of dynamization, identify the factors associated with its success or failure, and analyze the cost compared with exchange nailing...

Recently, we experienced a case where the diagnosis and management of a deep femoral artery rupture was delayed. This vascular complication occurred during the insertion of a distal interlocking screw of a proximal femoral nail for the fixation of an intertrochanteric femur fracture. A 79-year-old male patient was diagnosed with a right intertrochanteric fracture after a fall. We fixed the fracture with a proximal femoral nail (Zimmer® Natural Nail™ System). One day after the procedure, the patient complained of pain and swelling on the anteromedial side of his middle thigh followed by hypotension, anemia and prolonged thigh swelling...

The piriformis fossa is the ideal portal of entry for antegrade interlocking nailing. Localizing this portal can be difficult and its eccentricity leads to complications. This prospective comparative study was designed to compare an innovative way to obtain the ideal portal from inside the medullary canal in cases of plate failure and compare it to the classic antegrade portal. It included 41 cases (19 antegrade and 22 retrograde). The retrograde portal was significantly better in terms of entry time, radiation time, blood-loss, and wound length...

INTRODUCTION: We usually use short femoral nails for the treatment of trochanteric fracture of the femur. In this retrospective study, we investigated and compared the clinical results of the conventional intramedullary hip screw (IMHS) and the Asian IMHS, which is a redesigned version of the former. MATERIALS AND METHODS: The subjects were 42 patients; 21 treated with the Asian IMHS and 21 were treated with the conventional IMHS. From the clinical records, we retrospectively investigated the patients' age, sex, in-hospital waiting period for operation, operating time, intraoperative blood loss, walking ability before fracture and at discharge, and complication pertaining to the operation...

OBJECTIVE: Non-union after intramedullary nail fixation of femur shaft fractures is although infrequent but a challenging condition to treat. The treatment options available to deal with such a situation include exchange nailing, removal of nail and re-osteosynthesis with plating, or Ilizarov fixation. We believe that rotational instability, in the presence of a nail, is one of the main reasons for most of the non-union. We present our experience of plate augmentation leaving the nail in situ for non-union of femoral shaft fracture...

BACKGROUND: The integrity of bone-cement interface is very important for the stabilization and long-term sustain of cemented prosthesis. Variations in the bone-cement interface morphology may affect the mechanical response of the shape-closed interlock. METHODS: Self-developed new reamer was used to process fresh pig reamed femoral canal, creating cortical grooves in the canal wall of experimental group. The biomechanical effects of varying the morphology with grooves of the bone-cement interface were investigated using finite element analysis (FEA) and validated using companion experimental data...
