[Treatment of spinal fracture in ankylosing spondylitis].

Clinical guidelines for the treatment of vertebral fractures associated with ankylosing spondylitis are derived from case reports and a review of literature. The coincidence of paravertebral calcifications and fracture formations leads to problems in the establishment of a proper initial diagnosis. Therefore computed tomography and magnetic resonance imaging have to be employed to define the extent of fracture and the presence of spinal lesions.

[Morbidity and mortality in para-articular femoral fractures in advanced age. Results of a prospective study].

Unlabelled: This study was designed to determine risk factors and individual dispositions associated with morbidity and mortality in the operative treatment of hip fractures in elderly patients.

Patients And Methods: In a prospective clinical trial, a consecutive series of 278 patients (mean age: 78.7 +/- 6.

Proprioception of the cruciate ligaments: receptor mapping in an animal model.

Ten anterior and posterior cruciate ligaments (ACL and PCL) harvested from adult sheep were investigated under light microscopy for data on the frequency and localisation of neural structures. Serial sections of 25 microns thickness were stained with a modified gold chloride technique. Receptors were classified according to their histological structure.

[Local surgical measures in chronic wounds].

The treatment of chronic wounds is initiated by resection of gangrenous tissue, drainage of abscess formations, and--if necessary--primary resection of necrotic bone and joint structures in the phalanxes. The restoration of arterial blood perfusion in the periphery is a central part of wound management. Several surgical procedures such as necrosectomy, topical application of antiseptic solutions, and hydrocolloid wound dressings serve to create well-vascularized granulative tissue.

Proprioceptive mechanisms in the cruciate ligaments: an electromyographic study on reflex activity in the thigh muscles.

The hypothesis of a proprioceptive mechanism arising from mechanoreceptors in the cruciate ligaments and with efferences to the thigh muscles is investigated in an animal model. Electromyographic (EMG) studies of the quadriceps and hamstrings muscles were performed in six sheep anesthetized by intravenous injection of chloralose on applying static and dynamic shear forces to isolated fascicle bundles in the anterior (ACL) and posterior (PCL) cruciate ligaments at 200 to 500 N and 50 to 200 N/sec, respectively. With the help of an external fixator, the knee joint position was varied at 25 to 150 degrees.
