There is some clinical evidence to suggest that fractures of long bones heal more rapidly in patients with severe head injury or acute traumatic spinal cord injury. The mechanism underlying this orthopedic phenomenon is not well understood. The aim of the current study was to investigate the bone healing of diaphyseal femoral fractures in patients with concomitant head or spinal cord injuries a...

INTRODUCTION Posterior hip dislocation of the hip with acetabular fracture is a challenging problem to treat. Such dislocations are associated with avascular necrosis of the femoral head if neglected. Managing such conditions with total hip replacement (THR) is very difficult because of associated altered anatomy. CASE PRESENTATION We hereby report a two-year neglected hip dislocation with as...

Purpose The purpose of this study is to analyze the relationship between significant femoral neck shortening (SFNS) and bone density after three parallel screw fixation in valgus impacted femoral neck fracture, and to analyze the risk factors for SFNS. Materials and Methods This is retrospective study of 83 patients. We performed univariate analysis for patient information, bone density, frac...

Introduction Unstable intertrochanteric hip fractures can be difficult surgical challenges. Screw and side plate devices reliably stabilize stable fracture patterns [1,2], but unstable fractures require a mechanically optimized device and better implant purchase in the femoral head. These fractures have been more prone to implant failure with standard devices [3, 4]. The trochanteric femoral na...

Fibrous dysplasia (FD) is a rare bone disorder in which normal medullary bone is replaced by fibro-osseous tissue. It typically presents in childhood with pain, skeletal deformities, gait abnormalities and occasionally, fatigue fractures. The management of FD remains a challenge. Surgical procedures have been developed to provide symptom relief, correct skeletal deformity and offer mechanical s...

OBJECTIVE Increasing evidence suggests long-term alendronate use may overly suppress bone metabolism, limiting repair of microdamage and creating risk for insufficiency fractures. The purpose of this study is to demonstrate an association between alendronate use and a specific pattern of low-energy femoral shaft fracture. DESIGN, SETTING, AND PATIENTS A retrospective review was performed of p...

Total hip arthroplasty in the young leads to difficult choices in implant selection. Until recently bone conserving options were not available for younger patients with deficient femoral head bone stock. The novel Birmingham Mid-Head Resection (BMHR) device offers the option of bone conserving arthroplasty in spite of deficient femoral head bone stock. Femoral neck fracture is a known complicat...

Hip resurfacing is an established treatment for osteoarthritis in young active patients. Failure modes include femoral neck fracture and prosthesis loosening, which may be associated with medium-term bone adaptation, including femoral neck narrowing and densification around the prosthesis stem. Finite element modelling was used to indicate the effects of prosthesis sizing and positioning on the...

BACKGROUND Individuals with osteoporosis are predisposed to hip fracture during trips, stumbles or falls, but half of all hip fractures occur in those without generalised osteoporosis. By analysing ordinary clinical CT scans using a novel cortical thickness mapping technique, we discovered patches of markedly thinner bone at fracture-prone regions in the femurs of women with acute hip fracture ...

Background: Femoral head osteonecrosis is a progressive disease with disabling outcomes in hip joint if not treated.This study was designed to compare the effects of zoledronic acid plus vitamin E versus zoledronic acid alone insurgical induced femoral head osteonecrosis in rabbits.Methods: 26 Japanese white adult normal male rabbits at 28-32 weeks old were undertaken surgical femoraldislocatio...
