INTRODUCTION Painful fractures of the spine pose a serious clinical problem which gains in importance with the increasing ageing of our population. When conservative treatment of these fractures fails, with vertebroplasty and kyphoplasty we have two percutaneous minimally invasive stabilising procedures at our disposal. PATIENTS AND METHODS We performed a(More)
Pyogenic infections of the spine are relatively rare with an incidence between 1:100,000 and 1:250,000 per year, but the incidence is increasing due to increases in average life-expectancy, risk factors, and medical comorbidities. The mean time in hospital varies from 30 to 57 days and the hospital mortality is reported to be 2–17%. This article presents(More)
STUDY DESIGN Multicenter retrospective case series. OBJECTIVE To determine relevant clinical presentation and outcome of human immunodeficiency virus (HIV)-positive patients with spondylodiscitis as a function of the treatment. SUMMARY OF BACKGROUND DATA This is the first study comparing the clinical outcome of HIV-positive patients with(More)
BACKGROUND Fusion of lumbar spine segments is a well-established therapy for many pathologies. The procedure changes the biomechanics of the spine. Initial clinical benefits may be outweighed by ensuing damage to the adjacent segments. Various surgical devices and techniques have been developed to prevent this deterioration. "Topping off" systems combine(More)
BACKGROUND Osteoarthritis (OA) is the most common degenerative arthropathy. Load-bearing joints such as knee and hip are more often affected than spine or hands. The prevalence of gonarthrosis is generally higher than that of coxarthrosis.Because no cure for OA exists, the main emphasis of therapy is analgesic treatment through either mobility or(More)
Pedicle screw fixation is the standard technique for the stabilization of the spine, a clinically relevant complication of which is screw loosening. This retrospective study investigates whether preoperative CT scanning can offer a predictor of screw loosening. CT-scan attenuation in 365 patients was evaluated to determine the mean bone density of each(More)

Es wird gefördert durch das Bundesministerium für Bildung und Forschung (BMBF 01GH0605) mit dem Ziel, Infrastruktur und studienspezifische Expertise im Bereich der chirurgischen Disziplinen aufzubauen. Die qualifizierte Weiterbildung für Ärzte, die eine Rotationszeit im CHIR-Net(More)
Vertebral fractures (VF) are a leading cause of morbidity in the elderly. In the past decade, minimally invasive bone augmentation techniques for VF, such as percutaneous vertebroplasty (VP) and kyphoplasty (KP) have become more widespread. According to the literature, both techniques provide significant pain relief. However, KP is more expensive and(More)
Pathologic bone fractures in cryosurgery of bone tumors have been described in literature. This study utilizing a sheep model should prove the possible reduction of potential fracture while using a new miniature cryoprobe minimizing tissue damage and providing accurate control of the ablation process. Furthermore, postoperative histological changes should(More)
BACKGROUND Percutaneous cement augmentation systems have been proven to be an effective treatment for vertebral compression fractures in the last 10 years. A special form available since 2009 is the radiofrequency kyphoplasty (RF) in which the applied energy raises the viscosity of the cement. The aim of this study is to find out if a smaller cement amount(More)
