Divergent descriptions of the anatomic location and biomechanical function of the iliotibial tract (IT) can be found in the literature. This study attempted to obtain exact data regarding the anatomic course and material characteristics including the biomechanical properties of this structure. The following were its aims: (1) anatomical investigations of(More)
STUDY DESIGN Comparison was made of the accuracy of a pedicle bore performed by conventional technique and by using an individual template in the lumbar spine of cadavers. OBJECTIVES The fixation of pedicle screws necessitates a high amount of surgical skill and experience to avoid lesions of nerves and vessels. By using individual templates in a cadaver(More)
AIM The aim of our investigations was to answer the question of whether the radiologic classification according to the investigations of Nasca has prognostic relevance for congenital scoliosis. Based on our results, a therapeutic concept was given. PATIENTS AND METHODS Radiographs of 49 patients with a congenital scoliosis were classified according to(More)
Presently, extracorporeal shock-wave therapy (ESWT) is not yet a standard therapeutic technique in orthopaedics. The mechanism for the analgesic effect or the effect of shock waves on osseous defects are still unknown. With the help of a review of the literature, indications and success rates for ESWT in the treatment of non-unions are outlined, while(More)
Typically obturator nerve blockade is used to relieve hip pain. It sometimes only has a minor effect in resolving symptoms. This clinical observation led us to examine comprehensively the sensory nerve innervation of formalin-fixed hip joint capsules. Following macroscopic preparation, the area of the hip joint capsule was inspected with the aid of an(More)
AIM OF THE STUDY Osteoporotic vertebral fractures are an ailment of the aging population of increasing incidence and high socioeconomic impact. Intractable pain causing significant morbidity leads to long-term hospitalisation. Kyphoplasty offers a new minimal invasive operative stabilisation procedure for these vertebral compression fractures. This study is(More)
The transplantation of human allograft for restoration and filling of cortical bone defects is well known. Our aim was an experimental investigation of the mechanical stability of the often used femoral head spongiosa depending on the caliber and extent of the allograft. To evaluate the orientation of the trabecular structures of the femoral head and relate(More)
OBJECTS Beta tricalciumphosphate pellets loaded with individualized antibiotics may represent novel options in the treatment of osteomyelitis and infectious bone disease. Here, the in vitro antibiotic elution of vancomycin and gentamicin from the synthetic bone graft substitutes Cerasorb(®) and Cerasorb M(®) was tested. METHODS Antibiotic elution and(More)
QUESTION As part of our study, the effectiveness and patient's acceptance of the Wilmington-brace is to be evaluated. The effectiveness can be documented with the help of the primary correction achieved, especially in light of the fact, that the primary correction and the long-term results are directly dependant upon one another. MATERIAL AND METHOD We(More)
BACKGROUND Cervical disc nucleoplasty is a significant and clinically demonstrated innovation in percutaneous disc decompression in case of non-herniated disc protrusions or prolpase. It allows a percutaneous decompression via a 19-gauge needle under utilization of the Coblation technique and under C-arm control. Until now the patients suffering of a(More)
