[Ultrasound image of the lumbar spine and the lumbosacral transition. Ultrasound anatomy and possibilities for ultrasonically-controlled facet joint infiltration].
Is sonography helpful in facet joint infiltration of the lumbar spine? ⋯ This method is a secure and economic (extra time 2-4 min.) alternative to clinically guided infiltration. Flouroscopy guided infiltration is needed only in anatomical variations or if strictly intraarticular application is necessary.

[Use of new biochemical markers in diagnosis of aseptic hip endoprosthesis loosening].
Aseptic loosening of endoprosthesis is the most important problem in total hip arthroplasty. The diagnosis of aseptic loosening is based on anamnesis, the clinical findings, the radiography and scintigraphy. Despite the multitude of diagnostic possibilities it is still a problem to get an exact and early diagnosis. ⋯ All other measured parameters of the bone metabolism showed no significant differences between the both groups. Our results show, that biochemical markers can provide relevant information of endoprosthesic loosening. We are now analysing in a prospective longitudinal study whether these parameters are also suitable to detect early endoprosthetic loosening.

[Spatial orientation and postural regulation in patients with idiopathic scoliosis].
Etiology of idiopathic scoliosis is unknown. In literature a primarily neurogenic disturbance of postural regulation is discussed with subsequent changes of the spine. In the present paper, individual functions of postural regulation in patients with idiopathic scoliosis were examined by neurophysiologic investigations and compared to a normal population. ⋯ It has not to be considered as probable that idiopathic scoliosis is caused by a disturbance of postural regulation.

Review[Thoracic outlet syndrome--an interdisciplinary topic. Experience with diagnosis and therapy in a 15-year patient cohort (80 trans-axillary resections of the 1st rib in 67 patients) and a literature review].
Because of its wide variety of symptoms, the neurovascular compression syndrome of the upper thoracic aperture or thoracic outlet syndrome (TOS) has to be distinguished from several differential diagnoses, especially orthopedic ones. It is mainly characterized by pressure lesion of the brachial plexus and secondly, by accompanying vascular damages. An indication for surgery exists in cases of persisting or increasing complaints or function loss of shoulder, arm or hand muscles as well as in cases with occurrence of vascular damage. ⋯ Our results after surgery (84.5% of complete resolution or improvement of symptoms) compare favorably to those given by other authors. The average follow-up period was 6.6 years (0.5-14 years). Our results confirm, that transaxillary resection of the first rib is the method of choice in the treatment of thoracic outlet syndromes.

[Proton spin tomography imaging of the rotator cuff in calcific tendinitis of the shoulder].
An analysis of the MR-images of 75 patients with calcifying tendinitis of the shoulder was performed. The aim of the study was to recognize characteristic findings of the calcific deposits and their relation to the involved tendons as well as the coincidence with additional degenerative alterations of the rotator cuff. The calcifications can be demonstrated with high accuracy (> 95%) in T1-weighted images as areas of decreased signal intensity. ⋯ Analysing two perpendicular planes the calcifications can be assigned to the corresponding anatomical structure. 83 percent were located in the supraspinatus tendon above the humeral head or in the superior part of the subscapularis tendon. Degenerative areas of the rotator cuff are demonstrated as small zones of increased signal intensity, abnormal morphology or discontinuity of the tendon. Only in one patient a partial tear could be found; 11 percent showed variable signs of degenerative alteration of the involved tendon.
