Osteoporosis among hospitalized patients with proximal femoral fractures in Assiut University Trauma Unit, Egypt.

The study was done to investigate osteoporosis prevalence in 275 hip fracture admissions at the Trauma Unit of Assiut University Hospitals and associated factors, which are understudied in our locality. Prevalence was 74.9%. Female sex, older age, low body mass index, and fall on the ground were associated with osteoporosis. PURPOSE: This study aims to identify osteoporosis prevalence in hip fracture admissions at the Trauma Unit of Assiut University Hospitals and to study the independent correlates of osteoporosis-related fracture. METHODS: A prospective cross-sectional study was carried out in 275 hip fracture patients admitted to the Trauma Unit of Assiut University Hospitals from January through December 2014 of both sexes aged 50 years and older. Exclusion criteria were polytrauma, major accidents, and history of chronic conditions and long-term medication associated with osteoporosis risk increase and bilateral hip fractures. For every patient, weight, height, and bone mineral density by dual-energy x-ray absorptiometry (DEXA) were recorded. Tests of significance for non-parametric data were used. The questionnaire included sociodemographic characteristics, dietary habits, lifestyle factors such as smoking and physical activity, and female obstetric and gynecological factors. RESULTS: Mean age was 70.82 ± 11.02 SD; 51.6% were males and 8.4% were obese. Fall on ground was in 81.1% of fractures. Osteoporosis (femoral neck T score ≤ -2.5 SD) prevalence was 74.9%. By univariable analysis, significant correlates were female gender, older age, normal BMI, and fall on the ground. Milk and cheese daily intake was significantly associated with lower prevalence of osteoporosis. In a multivariable logistic regression model, female sex, older age, low BMI, and fall on the ground were associated with osteoporosis. CONCLUSIONS: Osteoporosis prevalence is high among hip fracture patients and associated with female sex, increase in age, low BMI, and fall on ground. Strategies to prevent osteoporosis are needed to decrease hip fracture rates.

Salvage of failed dynamic hip screw fixation of intertrochanteric fractures.

Twenty-six patients with failed dynamic hip screw fixation of intertrochanteric fractures were included in this study. The mean age of the patients was 61 years (range, 38-84 years). Average limb shortening was 2.4 cm; 18 patients were treated with revision internal fixation and eight patients with prosthetic replacement. The decision depended on the physiological age of the patient, quality of bone, and condition of the femoral head and the acetabulum. The revision internal fixation group included DHS reinsertion in eight patients, valgus osteotomy and revision DHS fixation in six, while four patients were treated by valgus osteotomy and insertion of single-angled 130 degrees plate. The prosthetic replacement group included cemented Thompson endoprothesis in five patients and cemented total hip arthroplasty in three. The mean follow-up period was 31 months (range, 15-72 months). All patients of revision internal fixation group achieved fracture healing without bone grafting. Time to union averaged 17 weeks. Average gain in length was 2 cm Avascular necrosis of the femoral head occurred in one patient. Six patients of the prosthetic replacement group achieved good functional outcome and pain-free gait. The remaining two had unsatisfactory result.

An irreducible variant of intertrochanteric fractures: a technique for open reduction.

We report five cases of intertrochanteric fractures that needed open reduction after failed closed reduction techniques. In all cases the shaft fragment included the lesser trochanter, and there was a long spike on the head-neck fragment. This was evident clinically as the proximal shaft, pulled by the iliopsoas tendon, produced a swelling in front of the hip joint. Radiographically, the fracture was minimally comminuted. The anteroposterior view revealed upward riding of the shaft fragment, while lateral view showed the femoral shaft in front of the head and neck. We describe a three-step technique, which was applied for open reduction in these unusual cases. With the patient supine on a standard operating table, the fracture site was exposed. The limb was placed in full adduction and external rotation to slacken the iliopsoas tendon. A Hohmann retractor was then passed medial to the shaft and behind the fractured surface of the sunken femoral neck, levering it anteriorly. Traction in abduction and internal rotation was applied to complete the reduction. Additional iliopsoas tenotomy was performed in two patients. All cases were fixed with a dynamic hip screw and all fractures united uneventfully.

Resection-shortening-distraction for malignant bone tumours. A report of two cases.

We report two patients with malignant bone tumours treated by wide marginal resection in whom the residual bone defect was replaced by progressive distraction after allowing union to commence in the shortened position.
