Femoral neck stress fracture occured commonly in athlete and military recruit populations, some of them are bilateral. Bilateral femoral neck stress fracture that associated with other occupation is very uncommon. We report a bilateral femoral neck stress fracture case that presented with unilateral symptoms in a male shipman laborer. The patient was successfully treated conservatively. Stress ...

Although age-related variations in areal bone mineral density (aBMD) and the prevalence of osteoporosis have been well characterized, there is a paucity of data on femoral strength in the population. Addressing this issue, we used finite-element analysis of quantitative computed tomographic scans to assess femoral strength in an age-stratified cohort of 362 women and 317 men, aged 21 to 89 year...

BACKGROUND Coxa vara and pseudoarthrosis of the femoral neck after septic hip arthritis is a very rare disease. The aim of this study was to present a case with pseudoarthrosis of the femoral neck, with coxa vara after neonatal septic arthritis of the right hip, and treatment of the pseudarthrosis with proximal femoral valgus osteotomy. CASE REPORT A 12-month-old female, who had suffered neonat...

Bilateral femoral neck fractures are rare in the pediatric age group, and only a few cases have been reported following major trauma in children. A 9-year old girl presented with bilateral femoral neck fractures following a motor vehicle accident. The patient was managed with early operative fixation of the fractures with a successful outcome. This case highlights the importance of awareness of...

Osteonecrosis of the femoral head is an idiopathic, debilitating and progressive disease. A number of traumatic or non-traumatic animal models have been reported for research on osteonecrosis. This study was performed to compare the efficacy of femoral head osteonecrosis in rabbits by traumatic and non-traumatic methods. Twenty-seven New Zealand White rabbits were divided into three experimenta...

Femoral neck fractures resulting from pregnancy-associated osteoporosis is a rare condition. Herein, we report an undoubted case of pregnancy-associated osteoporosis in a 38-year-old primiparous patient with pre-existing anorexia nervosa who suffered bilateral femoral neck fractures in the third trimester and early post-partum period. Magnetic resonance imaging revealed femoral neck fractures a...

PURPOSE To report 3 patients operated on using medial hip arthroscopic portals, describe the surgical technique and clinical outcomes. METHODS Three medial portals were made, the first one at the posterior edge of the adductor longus muscle (posterior medial portal), the second one at the anterior (anterior medial portal) and the third at the posterior border of the adductor longus, 5 cm dist...

BACKGROUND The aim of this study was to develop and perform the 3D finite element analysis of a femoral head interior supporting device (FHISD). MATERIAL AND METHODS The 3D finite element model was developed to analyze the surface load of femoral head and analyze the stress and strain of the femoral neck, using the normal femoral neck, decompressed bone graft, and FHISD-implanted bone graft m...

The cortical strains on the femoral neck and proximal femur were measured before and after implantation of a resurfacing femoral component in 13 femurs from human cadavers. These were loaded into a hip simulator for single-leg stance and stair-climbing. After resurfacing, the mean tensile strain increased by 15% (95% confidence interval (CI) 6 to 24, p = 0.003) on the lateral femoral neck and t...

19 Objective: Avascular necrosis of femoral head and nonunion is a major complication 20 after the treatment of displaced femoral neck fracture in young adults. 21 The purpose of this study was to introduce a new technique using biodegradable 22 magnesium screws and vascularised iliac grafting for displaced femoral neck fracture 23 in young adults. 24 Methods: Totally 19 patients with displaced...
