In 24 cadaver knees the anterior cruciate ligament (ACL) was replaced by a bone-tendon-bone patellar tendon autograft in an endoscopic technique. This was carried out during an advanced arthroscopy course after intensive instruction and practice on a plastic model. When the knees were opened and evaluated according to the recent orthopaedic literature, only(More)
AIM Shoulder arthrodesis following prosthesis explantation or resection of the acromion has not often been described in the literature. The presented article analyses the special features and problems of these preoperative circumstances in 4 cases and discusses them within the entire group. PATIENTS AND METHOD Between 06/1987 and 02/2001, a total of 30(More)

Indikationen Irreparable Lähmung des Ramus profundus nervi radialis. Zusätzlich bei langstreckigem Nerventransplantat mit fraglicher Prognose.(More)
PURPOSE Intraoperative femoral fracture is a well recognized intraoperative complication of cementless total hip arthroplasty (THA). This study was designed to establish an in-vitro model for initiation of fractures of the femur in cementless THA and to assess the effect of fracture fixation by cerclage wiring using steel wire (Protasul). METHODS Ten(More)
Intraoperative femoral fracture is a well recognized technical complication of cementless total hip arthroplasty (THA). The aim of this study was to establish an in vitro model for initiation of fractures of the femur in cementless THA and to assess the effect of fracture fixation by cerclage wiring. An in vitro comparison of two methods of cerclage(More)
Between March 1994 and June 2003, 80 patients with brachial plexus palsy underwent a trapezius transfer. There were 11 women and 69 men with a mean age of 31 years (18 to 69). Before operation a full evaluation of muscle function in the affected arm was carried out. A completely flail arm was found in 37 patients (46%). Some peripheral function in the elbow(More)
Limited function due to paralysis following brachial plexus lesions can be improved by secondary operations of the bony and soft tissue. Between April 1994 and December 2000, 109 patients suffering from arm-plexus lesions underwent a total of 144 reconstructive operations guided by our concept of integrated therapy. The average age at the time of surgery(More)
AIM Dysplastic hips or dislocated hips lead to loss of muscle strength claudication, and finally to coxarthrosis. This study analytically compares the hip joint forces in normal, dysplastic hips and hips after implantation of a hip prosthesis for several positions. METHOD The results of 173 total hip replacements in 153 cases of either severe congenital(More)
Ziel der Untersuchung war es, das persistierende Lähmungsmuster nach traumatischen Arm-Plexus-Schäden festzustellen und daraus resultierende funktionsverbessernde Operationen im Rahmen eines Gesamtkonzepts darzustellen.Dazu wurden von 04/1994 bis 12/2000 bei 104 Patienten mit Plexusläsion prospektiv die Kraftgrade sämtlicher Muskeln der betroffenen(More)
