[Bristow surgical treatment of shoulder dislocation].

14 shoulders with recurrent anterior dislocation were treated with a modified Bristow procedure and had a 38 to 66 months follow up after surgery. Postoperatively no patient had recurrent anterior dislocation. 4 patients had an average loss of external rotation of 10-15 degrees, one patient had a non-union of the transplanted coracoid.

[Morphometric measurements in the area of the epiphyseal groove of the parietal vertebra in experimentally-induced scoliosis in rabbits].

In 3 rabbits we provoked a short-curved dorsolumbal scoliosis by costo-lumbal cerclage. In order to quantify with morphometric methods the morphologically by various authors described effect of pressure parallel to the axis of epiphyseal growth under Hueter-Volkmann's law, we measured the height and area of different parts of the epiphyseal plate in frontal semi-thin sections (Alcian-blue) by means of a pictoral analysis system based on a mini-computer. On the concave side, the side of increased pressure, we found a relative atrophy of the epiphyseal plate of 40% and a diminished area of 49%.

Rare fracture of a total hip replacement.

Material fractures in the femoral part of total hip replacements, a late complication, are usually observed in the shaft. In our case, a fatigue fracture of the ball-neck weld occurred 8 1/2 years after implantation of the prosthesis because of insufficient weld depth. Additional negative factors proved to be varus implantation and overloading of the prosthesis due to obesity.

[Functional variants in applying anatomical forearm splinting (author's transl)].

Two practical examples are given to demonstrate variants in the use of anatomical forearm-hand splinting in a child with arthrogryposis. Crucial to successful application had been thorough functional assessment carried out previously by the occupational therapist.
