[Bilateral necrosis of the lunate bone. A pathogenic study].

The incidence of clinically and roentgenologically manifest Kienböck disease was checked on the basis of a thorough analysis of 85 patients suffering from the condition. Apart from sex distribution and age at onset, particular importance was attached to certain "constitutional factors". The fact in all bilaterally affected patients the ulnar was smaller than average at the wrist, and the advanced signs of arthrosis were radiologically demonstrated in 81.8% of the patients, once again confirms that certain constitutional factors play a decisive role in the Pathogenesis of Kienböch disease. Their importance for treatment, and also for possible assessments for insurance purpose, is emphasized.

["Dislocation osteotomy" in the treatment of large juvenile bone cysts (author's transl)].

Dislocation osteotomy with subpositioning of the distal fragment - without additional implantation of bone material (!) - yields excellent results in the treatment of large juvenile bone cysts of the coxal end of the femur (Imhäuser), as confirmed by the author's own experience. The advantages of this procedure compared with other methods are described. Taking into consideration the two cases successfully treated by Imhäuser at the shaft of the upper arm in the same manner, it is demonstrated by describing the case of a patient with extended juvenile bone cyst in the region of the proximal humerus that here, too, dislocation osteotomy leads to complete cure within a short time, so that its increasing use appears justified.

[Large cyst of the ulnar head and simultaneous lunatomalacia].

The correlations between symptoms at the distal end of the ulna and lunatomalacia are discussed by demonstration of a case with large subchondral bone cyst within the head of the ulna and simultaneous lunatomalacia. The possible common factors with regard to the etiology are discussed.

[As to the traumatic etiology of the Freiberg-Köhler's epiphyseonecrosis (author's transl)].

There is demonstrated the case of a Freiberg-Köhler's epiphyseonecrosis developing without any doubt after a direct massive contusion of the forefoot by hit against the edge of a swimmingpool. While the X-ray from the date of accident only showed a tiny osseus avulsion fracture out of the base of the proximal phalanx II--in spite of the immediately taken accurate therapeutical provisions (by fixation with plaster and later on paviment dressing)--there took place a massive epiphyseonecrosis of the capitulum II within only three months.--The etiology of the necrosis--direct trauma of the nutritive arteries passing through the collateral ligaments--is discussed. There is given a reference to the particular problems arising by critical examination of similar cases for instance at medical reports.

[Modification of the operative technics for the ventralisation of the tuberositas tibiae (Maquet-Bandi) (author's transl)].

UNLABELLED: There is given a modification of operative technics for ventralisation of the tuberosity of the tibia (Maquet-Bandi-Operation). Similar to a sand-glass two triangular cortical/spongious bone grafts are taken from the medial side of the tibia, just beside the tuberosity. Their size can be determined exactly. After having chiseled the proximal part of the tuberosity from both sides and lifted it up, the bone grafts are put under it, one from the medial, the other one from the lateral side by the way, that the top of the triangle is looking in distal, the base in proximal direction. The cortical surfaces of the grafts, showing to the medial and lateral side, make sure the stable keeping place, while their spongious surfaces, showing to the internal side, by direct contact to the spongious backside of the tuberosity and its spongious bed guarantee the quick osseous consolidation. A minimal osteosynthesis by drilling 2 Kirschner-wires in ventro-dorsal direction through the tuberosity, the cortical part of the bone grafts up to the opposite cortex of the tibia finishes the operation. ADVANTAGES: 1. The bone graft can be taken directly at the field of operation. 2. The bone material is homogenous. 3. The cortical part of the grafts guarantee stable keeping place. 4. Their spongious parts make sure the quick osseous consolidation. 5. Minimal osteosynthesis is necessary.
