[Experiences with primary osteosynthesis in radial head fractures].

Displaced fractures of the radial head are indications for early surgery. The resection is unsatisfactorily leading often to an instable elbow in valgus deformity and to painful troubles in the distal radio ulnar joint. Prosthesis implantation has its own problems. Reconstructive surgery is obviously the best solution. 21 internal fixations in 20 patients were performed using small screws (and 2 plates) between 1968 and 1976. The functional and radiological results are excellent in 15 out of 19 controlled patients. 3 patients have a moderate reduction of the mobility, 1 patient a non-union. -We were impressed by 4 operative observations: The fractures and the displacements use to be unexpectedly important. There is usually a periostal bridge between the head fragments and the neck. That is why complete devitalization of the articular fragments is rare. In about half of our cases we found an important avulsion of the humeral articular cartilage. In 8 of 10 cases these avulsions were interposed in the fragments of the radius. Their removal is necessary for the reduction. -These observations should influence the indication for reconstructive surgery in fractures of the radial head.

[Subcutaneous Achilles tendon rupture. Experiences with 99 operations on fresh injuries].

Influenced by new publications about the conservative treatment of the rupture of the Achilles tendon we reviewed our own material. 99 operations were performed within the first week after the accident. There were 7 slight early complications, one rerupture after 3 months, healed after resuture, and 1 osteodystrophy. 94 patients answered our question forms, and the result of 92 operated ruptures could be examined personally within an average of 5 years after the accident. 2/3 of the patients had a measurable--although unimportant--muscular atrophy but only 1/5 of them felt a weakness. 7 patients had a reduced movement of the ankle joint. Only one patient was disabled by the scar. 85 patients have taken up again the same sport, only one had to give up. The result of the primary suture of fresh Achilles tendon ruptures is good if the operation is performed as soon as possible and by using a strictly atraumatic technique.

[Operative treatment of distal tibial fractures. Technique of osteosynthesis and results in 128 patients (author's transl)].

Fractures of the distal tibia including the articular surfaces have considerably increased. A simple classification based on the surgical findings is recommended and some particular diagnostic criteria are pointed out. The operative approach and technique have been described in detail. Due to special osteosynthetic implants alignment of the axis, anatomical reconstruction of the articular surfaces, and stabilisation in comminuted fractures has been greatly facilitated. Cancellous bone from the ipsilateral proximal tibia is advantageous for the filling of metaphyseal defects in juvenile patients. Post-operative treatment has to be individualized with emphasis on functional treatment. Between 1963 and 1973, 128 osteosynthetic reconstructions for fracture of the distal tibia have been performed. Primary fusion was not necessary in any patients. 121 patients could be reviewed an average of 4 years after injury. Late complications (delayed healing, refracture, late infection etc.) were rare (about 7%) and healed without further sequelae. Secondary correction of the axis or fusions were not required. In 90% the functional results after these serious fractures were good. 85% returned to athletic activity, only 5% are disabled.
