PURPOSE 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(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)
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)
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)
INTRODUCTION 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(More)
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)
BACKGROUND The 360° fusion of lumbar segments is a common and well-researched therapy to treat various diseases of the spine. But it changes the biomechanics of the spine and may cause adjacent segment disease (ASD). Among the many techniques developed to avoid this complication, one appears promising. It combines a rigid fusion with a flexible pedicle(More)
BACKGROUND Postoperative wound infection is a preventable risk. One potential postoperative complication is blistering, which leads to increased pain, delayed healing, and higher care costs. The incidence of wound blisters has been reported to be between 6 and 24%. The aim of this study is to assess whether the risks of postoperative blistering and wound(More)
STUDY QUESTION 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(More)
INTRODUCTION Focusing on spondylodiscitis in elderly patients current literature does not contain much information. METHOD We performed a retrospective case series (n = 32) comparing conservative (group 1; n = 16) versus operative (group 2; n = 16) treated spondylodiscitis patients aged > or =65 years (mean age 74.9 years) from January 2002 to April 2004.(More)
