Cement reinforcement for the treatment of osteoporotic vertebral fractures is efficient mean with high success in pain release and prevention of further sintering of the reinforced vertebrae; however, the technique does not allow to address the kyphotic deformity. Kyphoplasty was designed to address the kyphotic deformity and help to realign the spine. It(More)
Bei schwerer Osteoporose ist der progressive Kollaps mehrerer Wirbelkörper mit konsekutivem Haltungsverlust ein ungelöstes Problem. Die medikamentöse Therapie greift zu langsam, um diesen Verlauf aufzuhalten. Die zunehmende Erfahrung mit der Vertebroplastik hat dazu geführt, bei hochgradiger Osteoporose die mehrsegmentale Zementierungen durchzuführen. Von(More)
Minimally invasive augmentation techniques of vertebral bodies have been advocated to treat osteoporotic vertebral body compression fractures (VBCFs). Kyphoplasty is designed to address both fracture-related pain as well as kyphotic deformity usually associated with fracture. Previous studies have indicated the potential of this technique for reduction of(More)
Cement augmentation using PMMA cement is known as an efficient treatment for osteoporotic vertebral compression fractures with a rapid release of pain in most patients and prevention of an ongoing kyphotic deformity of the vertebrae treated. However, after a vertebroplasty there is no chance to restore vertebral height. Using the technique of kyphoplasty a(More)
In severe osteoporosis progressive collapse of multiple vertebrae is an unsolved problem. Medical treatment appears to be too slow to prevent the course. The evolving experience with vertebroplasty led us to treat these problems with more extensive cement injections. Of 362 patients who were treated with percutaneous cement injection over a 5-year period,(More)
STUDY DESIGN A prospective case control study design was conducted. OBJECTIVES The purpose of the current study was to determine the intraoperative radiation hazard to spine surgeons by occupational radiation exposure during percutaneous vertebroplasty and possible consequences with respect to radiation protection. SUMMARY OF BACKGROUND DATA The(More)
Between December 1995 and June 1996, we reviewed 53 consecutive patients who were at least 80 years old and had undergone a revision of a hip prosthesis between June 1988 and June 1995. Three patients (6%) had died after the operation in the hospital. Thirty-five patients were still alive with a mean follow-up of 4.0 years (range, 1.0-7.3 years). At(More)
We followed 39 patients with 40 revision hip arthroplasties using the Wagner stem. Mean follow-up was 65 (29–108) months. There were 12 intraoperative proximal femoral fractures, which all united, five postoperative dislocations not related to subsidence, and two loose stems that were revised. Clinical improvement was best for pain. Once the stem was(More)
BACKGROUND This study intends to prove the hypothesis that preoperative autologous blood donation in total knee arthroplasties (TKA) is dispensable. PATIENTS AND METHODS The study comprises a prospective analysis of 81 consecutive TKA without preoperative autologous blood donation (AB-donation). Guidelines for blood retransfusion were used. Surgery, as(More)
STUDY DESIGN Technical note and case series. OBJECTIVE To introduce an innovative minimal-invasive surgical procedure reducing surgery time and blood loss in management of U-shaped sacrum fractures. SUMMARY OF BACKGROUND Despite their seldom appearance, U-shaped fractures can cause severe neurological deficits and surgical management difficulties.(More)
