Introduction Non-union of femur fracture is a known complication, managed by various methods, including exchange nailing. Additional bone grafting is known to enhance fracture healing. Percutaneous bone grafting has been reported for tibia and humerus in the literature. The authors report a series of aseptic non-union of the femoral shaft managed by exchange nailing, supplemented with percutane...

OBJECTIVE To present the clinical and radiological results of treatment of periprosthetic fractures of the femur after hip and knee replacements. SUBJECTS AND METHODS Thirty-four patients (8 males and 26 females) with 34 fractures of the femur complicating hip and knee replacements are the subjects of this report. In 21 cases, the fracture affected the femur after hip replacement, and in 13 c...

The study describes the acoustic emission (AE) activity during human femur tissue fracture. The specimens were fractured in a bending-torsion loading pattern with concurrent monitoring by two AE sensors. The number of recorded signals correlates well with the applied load providing the onset of micro-fracture at approximately one sixth of the maximum load. Furthermore, waveform frequency conten...

We present a case of fatigue fracture of the femur after navigated total knee arthroplasty with the Orthopilot system. A 60-year-old woman with rheumatoid arthritis and osteoporosis (T-score = -3.1) reported increasing pain of the thigh 8 weeks after the surgery. A fatigue fracture of the right femur through the pinholes was diagnosed and stabilized with an intramedullary nail, achieving union ...

The treatment of basicervical femoral fractures remains controversial. The aim of this study was to examine the efficacy of intramedullary nail use in the surgical treatment of basicervical fractures. In total, 28 patients with basicervical fractures treated with proximal femoral nails were examined retrospectively. Fracture healing was observed in all patients, who were followed at least for 6...

The optimal management of pathologic long bone lesions remains a challenge in orthopedic surgery. The goal of the current study was to investigate the effect of defect depth on the torsional properties of the distal femur. A laterally placed distal metaphyseal cylindrical defect was milled in the cortex of the distal femur in 20 composite models. The proximal extent of the defects was constant....

The objective of this study was to evaluate right proximal femur shape as a risk factor for incident hip fracture using active shape modeling (ASM). A nested case-control study of white women 65 years of age and older enrolled in the Study of Osteoporotic Fractures (SOF) was performed. Subjects (n = 168) were randomly selected from study participants who experienced hip fracture during the foll...

Combined fracture neck femur with anterior dislocation of the head of femur is a very rare injury with little resources available in the literature. This case report describes a case that was treated by open reduction and internal fixation with 2-year follow-up showing good radiological and functional outcome. Functional evaluation was done according to Merle d'Aubigné score modified by Matta J...

Background: This study evaluates submuscular locked plate in the pediatric femoral shaft fractures at the age from 6 to 12 years old. Methods: A prospective study was done on 30 patients with fracture shaft femur. 18 of them were males and 12 of them were females. Fixation of all cases was done with a submuscular locked plate using the cluster technique. Results: All fractures healed within 6 w...
