Predictive value of Singh index and bone mineral density measured by quantitative computed tomography in determining the local cancellous bone quality of the proximal femur.

Objective: The purpose of this study was to assess the predictive value of the Singh index as well as quantitative computed tomography for the in vitro local mechanical competence of the cancellous bone of the proximal femur.

Design: An experimental study examining the relation between mechanical properties and bone mineral density of the femoral neck determined in vitro and the clinical estimated Singh index on X-rays.

Background: Evaluation of the predictive value of the Singh index, an inexpensive and simple technique for the mechanical properties of the cancellous bone of the proximal femur.

[Therapy of para-articular hip fractures in the elderly].

Unlabelled: Fractures of the hip in old patients are life-threatening events. A steady increase of that fracture type is likely in the near future. Surgical therapies and strategies have to consider the special requirements and problems of geriatric patients to achieve better results.

[Fractures of the upper extremity in the elderly].

Problem: The primary goal in treating fractures in elderly persons is safe and rapid restoration of their functional capabilities to secure independence in everyday activities. The intention of this paper is to present an overview of treatment principles useful in this age group.

Methods: We analysed a series of 404 patients above the age of 70 years who underwent surgery for fractures of the arm between 1981 and 1997.

Drug prophylaxis of deep vein thrombosis in traumatology: is there a benefit of a score in outpatients?

Introduction: Guidelines are lacking for the administration of drug prophylaxis of deep vein thrombosis (DVT) in outpatients. This study attempted to develop such a guideline in the form of a score.

Patients And Methods: In a prospective study of 731 outpatients with injury or surgery of the leg or pelvis a score was assigned based on "simulated physiological conditions" of the venous flow, including breathing, mobilization (activity of daily live), weight bearing and range of motion of joints of the lower extremities, lesions of the venous endothelium, date of injury, and localization of injury.

[Arthroscopic stabilization of anterior shoulder instability with bioresorbable tacks].

We examined 38 patients with an arthroscopic bioabsorbable tack repair for anterior shoulder instability in a prospective evaluation. The mean follow-up was 22 months (range 12 to 33). The average age was 28.
