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)
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)
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)
The treatment of traumatic brachial plexus lesions follows sequential steps. After acute therapy (phase I), neurological diagnostics (phase II), neurosurgery and postoperative treatment (phase III/IV), reconstructive operations (phase V) can be indicated and performed. In most cases an insufficient grade of muscle power remains. Within 6 months after(More)
AIM The surgical reconstruction of the dorsiflexion of the wrist and the abduction of the thumb in paralyzed radial nerve for the improvement of the useability of the hand is described. Likewise, the early functional subsequent treatment is described. Indications and contraindications are represented in detail. METHOD Between October 1997 and May 2000 we(More)
When infection of implants is suspected, optimal management requires accurate confirmation or exclusion of infection. However, in spite of demonstrative clinical signs cultures of smears or chemical parameters of inflammation frequently are ambiguous. Scintigraphy with indium-labeled white blood cells (WBC) has been reported to be sensitive and specific in(More)
We report the symptoms, clinical findings, and treatment of a patient with an extra-articular benign giant-cell tumor of the patellar ligament. Between the years 1966 and 1996 no similar case has been found to be documented by a Medline search. On palpation, a soft, mobile lesion, the size of a pigeon's egg, was felt in the lateral region of the patellar(More)
The aim of this study was to evaluate persistent patterns of paralysis after traumatic brachial plexus lesions. As a result, consecutive reconstructive operations according to our differential therapy concept are presented. Between 04/1994 and 12/2000 in 104 patients with brachial plexus palsy, the grade of muscle power of the affected upper extremities was(More)
