This study compared the biomechanical properties of bone-stapling techniques with those other fixation methods used for stabilizing tibial tuberosity fractures using 3-dimensionally (3D)-printed canine bone models. Twenty-eight 3D-printed models made from computed tomography scan files were used. Tibial simulated osteotomy. All samples divided into 4 groups. Group 1 was stabilized a pin and ten...

OBJECTIVES An epidemiological study of young adults was conducted to determine whether environmental exposure to lead during childhood was associated with current adverse neurobehavioural effects. METHODS The exposed group consisted of 281 young adults who had been exposed environmentally to lead as children and the unexposed referent group consisted of 287 age and sex frequency matched subje...

Bone loss with large defects poses a complex and challenging problem in primary and revision knee arthroplasty. The defects are often irregular and difficult to quantify. One of the techniques available to restore bone in such cases is Knee Impaction Bone Grafting (KIBG); however, the clinical literature to support this technique is weak. Since 2006 we have used impaction bone grafting for cont...

Introduction: Osteoarthritis of the knee is one most common causes disability among elderly population. OA clinically presents as flexion with varus deformity. Various methods to manage bone defects during TKR surgery have been described like use Bone cement, grafts, metal wedges and augment Extension tibial stem in various permutations combinations. In this study we are evaluating results defe...

PURPOSE Our research was aimed at studying the radiographic and histological outcomes of using flexible intramedullary nailing (FIN) combined with Ilizarov external fixation (IEF) versus Ilizarov external fixation alone on a canine model of an open tibial shaft fracture. MATERIALS AND METHODS Transverse diaphyseal tibial fractures were modelled in twenty dogs. Fractures in the dogs of group 1...

Nonunion is known to occur in up 10% of all bone fractures. Until recently, the treatment options considered cases delayed union and nonunion focused on revision surgery improvement local healing. Lately, teriparatide has been introduced as an osteoanabolic factor that induces fracture healing with or nonunions. We report a series five nonunions treated teriparatide: unions atypical femoral fra...

INTRODUCTION Traumatic uncontained bone defect in the knee joint is one of the most serious knee injuries. As the knee joint is the main weight-bearing joint of the body, the problem of weight loading should be addressed while restoring the bone defect. However, no consensus exists regarding the treatment of this injury. PRESENTATION OF CASE Two patients in separate cases initially sustained ...

OBJECTIVES The development of computer-assisted surgery in total knee arthroplasty continues its search for better accuracy in the spatial positioning of prosthetic components and in achieving the best ideal ligament balance. Many studies have underscored the value of computer-assisted navigation in obtaining precise bone cuts in terms of both orientation and location, which would optimize bone...

Prosthetic knee replacement is a surgical procedure designed to restore knee joint function in cases of advanced osteoarthritis and fracture. Since tibial morphology and microstructure vary among different individuals, the surgeon’s anatomical expertise and knowledge of various implant designs is essential. In order to contribute to the pre-surgical diagnosis of bone degradation, we investigate...

The effect of resistance training on tibial cancellous and cortical bone was evaluated in rats by using static histomorphometry and Northern analysis. Five-month-old male Sprague-Dawley rats were randomly assigned to exercise (Ex; n = 8) or control (Con; n = 4) groups. Animals were operantly conditioned to press two levers, facilitating full extension and flexion of the hindlimbs ("squats"), wh...
