This article describes the critical clinical sequelae of a patient with diffuse idiopathic skeletal hyperostosis who sustained an acute iatrogenic thoracic vertebral body fracture with subsequent spinal cord injury after a total hip replacement, with a final lethal course.A 57-year-old woman was referred to the authors' institution after undergoing a total(More)
INTRODUCTION The surgical treatment of displaced proximal humeral fractures (ORIF) is a perpetual challenge to the surgeon. For this reason, the principle of polyaxiality was developed to provide an improved primary stability of the fracture through better anchorage of the screws, especially in osteoporotic bone. The aim of this study was to present(More)
AIMS Our aim was to investigate the outcomes of patients with a displaced fracture of the glenoid fossa who are treated conservatively. There is little information in the literature about the treatment of these rare injuries non-operatively. PATIENTS AND METHODS We reviewed 24 patients with a mean age of 52 years (19 to 81) at a mean of 5.6 years (11(More)
BACKGROUND It is still not clear which method is the most efficient for treating primary traumatic anterior shoulder dislocation. Immobilization in external rotation has become increasingly discussed within the last 10 years. The aim of this study was to evaluate the rate of recurrence and clinical outcome of the immobilization in external rotation after(More)
BACKGROUND There is no biomechanical basis to determine the influence of different length of the central peg of the baseplate anchored within the native scapula in glenoid defect reconstruction in cases of degenerative or posttraumatic glenoid bone loss in reversed shoulder arthroplasty. OBJECTIVE The purpose of this study was to analyse the stability of(More)
Das chronisch dezentrierte Ellenbogengelenk nach einer Luxationsfraktur stellt eine operative Herausforderung dar. Bei einer Insuffizienz des Processus coronoideus über 40 % sind eine Rezentrierung über einen Knochenaufbau sowie eine zusätzliche ligamentäre Stabilisierung erforderlich. Als mögliche Techniken werden unterschiedliche Allografts und Autografts(More)
INTRODUCTION The sales of recreational trampolines have increased during the past few years. Severe injuries are associated in part with trampoline sport in the domestic setting. Therefore, this study was conducted to confirm the hypothesis of an increase in trampoline-related injuries in conjunction with the increasing sales of recreational trampolines and(More)
Aufgrund der anatomischen Besonderheiten sind Luxationen des Glenohumeralgelenks häufig. Verschiedene Prädispositionsfaktoren einer möglichen Dislokationsarthropathie werden in der Literatur diskutiert. Grundsätzlich entsteht der größte Knorpelschaden im Rahmen des sog. „first hit“, der traumatischen Erstluxation. Das Alter zum Zeitpunkt der Erstluxation(More)
Frame stability in Ilizarov external fixators is mainly dependent on the tension of the transosseous wires, which are clamped to the ring by connection bolts. It was the purpose of this biomechanical study to investigate the holding capacity of a modified bolt design featuring a ruffled wire-bolt interface (TrueLok™) and its influence on wire stiffness in(More)
Study design:Retrospective chart review.Objectives:Heterotopic ossification (HO) affecting the hips is a common complaint of patients suffering traumatic spinal cord injury. However, the incidence of HO of the shoulder is considerably rare. In this context, we report on our results of 13 patients with a total of 21 cases of shoulder HO and single-dose(More)
