[Femur head necrosis. Diagnosis and morphologic analysis using roentgen, scintigraphy, computerized tomography and magnetic resonance tomography].

35 patients with a total number of 53 AVN were examined with conventional radiographs (n = 53), radionuclide scans (n = 37), CT (n = 19) and MRI (n = 53). Findings were classified according to FICAT (stage 0-IV). With a sensitivity of 96.2% and a specificity of 98.1% MRI proved to be the most accurate imaging modality especially in early stages. CT proved to be a reliable technique, too, although accuracy was less compared with MRI. Radionuclide scanning was of minor value with a sensitivity of 62.1% and a specificity of 59.5%. Typical findings with plain radiographs, radionuclide scans, CT and MRI in different stages of AVN are described.

[Extracorporeal shockwave therapy in epicondylitis humeri ulnaris or radialis--a prospective, controlled, comparative study].

AIM OF THE STUDY: Has extracorporal shockwave therapy in chronic golfer's elbow comparable results as in tennis elbow? METHOD: 30 patients for extracorporal shockwave therapy who suffered from chronic medial epicondylitis (group I) and 30 patients with persistent tennis elbow (group II) received 500 impulses of 0.08 mJ/mm2 three times at weekly intervals. The final follow-up examination was done after 24 weeks. RESULTS: Significant differences in relief of pain and improvement of function were observed in favour of group II. Good or excellent outcome was found in only 27% for the epicondylitis humeri ulnaris, but in 60% for epicondylitis humeri radialis. CONCLUSION: The indication for extracorporeal shock-wave therapy in medial epicondylitis must be questioned.

[New classification of recommendations for forensic assessment of patients with scoliosis].

In 1977, for the first time, a recommendation for the expert evaluation of scoliosis-sufferers was given out. On the basis of this a new classification followed, which takes into consideration modern orthetics and new operative procedures. Unchanged are the classifications of incapacity to work with regard to decreasing lung capacity. The levels of vital capacity are still the main factor for determining lung capacity.

[Initial results of the surgical treatment of scoliosis with the Cotrel and Dubousset CD instruments].

At the Orthopaedic University Hospital Muenster 50 patients were surgically treated according to the Cotrel and Dubousset technique from June 1985 to October 1986. An outstanding characteristic of this method is the three-dimensional correction of the curve without exclusive application of distraction or transverse forces, bringing about excellent stability. By means of this operation an average preoperative angle of 63.4 degrees could be diminished to 33.9 degrees, meaning a gain of correction of 46.5%. Complications occurred essentially due to insufficient experience with this technique in the first patients operated on. After sufficient training this procedure is as practicable as the Harrington technique.

[Laceration of the vessels of the kidney hilus. A complication not previously described in halo extension treatment].

During the last years the halo traction proved to be an appropriate preoperative procedure to provide the spinal region with corrective forces, although several complications became known. As a complication unknown as yet a laceration of the renal hilus vessels is described, and the possible causes are discussed. Consequently, in case of abdominal symptoms and signs, a possible intraabdominal or retroperitoneal vascular lesion must be taken into consideration besides the well-known spinal-traction/spinal-cord-traction-syndrome.

[Long-term results of the conservative treatment of scoliosis using the Chêneau brace].

At present, we survey 52 patients who had been fitted with Chêneau braces in the years 1978 to 1980. The average primary correction of the single curved thoracic, single curved lumbar, and double curved scolioses amounted to 41%. The best late results are to be expected in the single curved thoracic and single curved lumbar scolioses that presented corrections of 14.2% and 9.2%. In the double curved scoliosis we found a correction of 5.5% of the thoracic and 5.6% of the lumbar curves. The Chêneau orthosis was well accepted by the patients. A final valuation, however, will not be possible till some years have passed.
