[Compression neuropathy of the median nerve at the wrist joint caused by chondroma].

The case is reported of a 75-year old patient with diabetes, who suffered from a typical carpal tunnel syndrome, which was diagnosed by a neurologist. On the X-rays of hand and wrist there were no pathological findings. A small, clinically almost inapparent induration at the palmar and radial side of the wrist was found. Ultrasonography and CT-scan showed a tumor with compression of the median nerve. At operation the authors excised a tumor which on histological investigation was compatible with a soft tissue chondroma. Full recovery followed local excision with decompression of the median nerve. Soft tissue chondromas localised to the hand and wrist are extremely rare. A few cases have been described in the literature which led to a nerve compression.

[Results of screw fixation of the scaphoid pseudarthrosis].

MATTI-RUSSE's cancellous graft is successful in the management of scaphoid pseudarthrosis. The necessity of post-operative immobilization of the wrist, usually previously immobilized, for up to 16 weeks is its disadvantage. Screw fixation including radial styloidectomy and a small cancellous graft is an alternative abbreviating immobilization to only 2 to 6 weeks. the follow-up of 26 patients thus operated revealed osseous union in 19 cases. The failures were due to lack of proper indication or faulty technique. In spite of the correct position of the scaphoid screw one pseudarthrosis did not heal, the clinical result being satisfactory. The procedure described permits early remobilization of the wrist. Failures, also described by other authors, can be avoided by proper indication and technique.

[Local therapy in a case of intravenous mercury injection].

Intravenous injection of metallic mercury is very rare. It may induce pulmonary and renal complications. Locally serious abscess formation may occur. Radical dissection and excision of affected venous system may result in a satisfactory outcome.

Collagen polymorphism in pathologic human scars.

The collagen type composition of normal and pathologic scars was examined in comparison with normal skin from the same individual. Particular care was taken to separate scar tissue from adjacent normal dermis. After urea extraction, the tissue specimens were cleaved with cyanogen bromide. The presence of the dermal collagen types I and III was deduced from the electrophoretic distribution patterns of the CNBr peptides in 12% SDS-polyacrylamide gels. The intensity of the type III specific peptide bands correlates with the type III content of the samples. Using this method, the presence of both type I and III collagen can be proved in normal as well as pathologic scars. The type III content in older normal scars is slightly increased, whereas the type III content of pathologic scars is significantly increased in comparison with the type III content of normal skin. The electrophoretic CNBr peptide distribution pattern of pathologic scar tissue is almost the same as that of fetal skin. Both are clearly different from the peptide pattern of normal adult skin.

[Injuries to the tibial plateau (author's transl)].

Conservative management of considerably displaced tibial head fractures tends to stretch the ligaments and damage the soft tissue. Plateau steps impair mobility and lead to secondary osteoarthritis. Therefore operative procedures are prefered: A buttressing plate supports the displaced condyle after exposure and immaculate reduction. Impacted fragments call for elevation and underlining by cancellous graft. Postoperatively, early active motion and late weight bearing is the rule. Operative procedures will only produce satisfactory results when performed by an experienced surgeon.
