[Value of primary stabilization of femoral shaft fractures in patients with simple and multiple injuries].

There is a variety of opinions about the optimal time when to stabilise femoral shaft fractures. The data of 100 patients were analysed in order to compare primary versus secondary intramedullary stabilisation. The rate of wound infections and of other concomitant complications was significantly lower after primary osteosynthesis which is therefore superior to secondary stabilisation in both kinds of patients--those with single and those with multiple injuries. In the group of 50 patients with immediate surgery four complications altogether were found, including one wound-infection, whereas in the group of 50 patients with delayed surgery there was a total of twelve complications, including five wound-infections and six cases of fat- and pulmonary-embolism. The average duration of stay in hospital was only 17 days after primary but 28 days after secondary surgery.

[Macroscopic and microscopic anatomy of the shoulder joint and the limbus glenoidalis].

Macroscopical and histological examinations were carried out in order to investigate the anatomy of the limbus glenoidalis, with respect to its surrounding structures such as tendons and ligaments. Basically the crosscut limbus glenoidalis has a triangular shape, however, especially in its anterior part, it has a meniscoid or labiate form. Histologically the limbus glenoidalis consists exclusively of connective tissue, rich in cells and fibers. It originates from the fibrocartilaginous rim of the glenoid surface, which merges into the hyalin cartilage. The bundles of fibers have a circular arrangement with radially and reticularly interwoven structures near the tendons of the biceps and triceps muscle.

[Stress to the lateral ankle joint ligament complex in confined imaging with an a.-p. radiation path].

Physical definition and laws of rotating systems will be stated. The application for supination in ankle joint shows, that lever action increases the force applied up to four times in case of stress X-rays in the a.-p. view. As quoted in literature, the test power of up to 25 kp means a loading of the lateral collaterals up to 100 kp. An additional iatrogenic rupture of already traumatically partially sprained structures seems possible. The critical judgement of five different methods producing stress X-rays of the ankle joint shows the weak points of this test system. Beck's method seems sufficient for precise statements and judgement of the stress X-ray tests without endangering ligaments so far unsprained.

[Anatomical separation and clinical importance of two different parts of the vastus medialis muscle].

In 32 corpses, either fresh or fixed, the deviations of the two heads (musculus vastus medialis longus and musculus vastus medialis obliquus) of the vastus medialis muscle from the long axis of the femur were measured. The deviations were between 15 and 18 degrees medially for the m. vastus medialis longus and between 46 and 52 degrees medially for the m. vastus medialis obliquus. Anatomical dissections of the vastus medialis muscle in 115 fixed thigh specimens could always demonstrate a clear separation between a long head of the muscle that inserts at the base (m. vastus medialis longus) and a short head (m. vastus medialis obliquus) that inserts at the medial margin of the patella. The plane of separation could be identified by a femoral nerve's branch in every case. In 17 instances the nerve's localization was superficial, in 57 in an areolar fascial plane, and in the depth between the muscles in 41 instances. The ramification of the femoral nerve's branch that runs along the separation plane showed four types of variation. With these investigations it was possible to distinguish between two individual heads of the vastus medialis muscle not only with regard to its function, but also to its anatomy.

[Treatment guidelines and results in severe open tibial fractures].

27 patients with compound fractures of the lower leg were treated according to the following scheme: Exact excision and surgical cleaning of the wound, reduction of the fragments without further exposure of the bone by additional incision, minimal osteosynthesis, stabilization by means of external fixation device and secondary closure of the accidental wound. During the last year we preferred the V-shaped arrangement in contrast to the tent shaped arrangement of the external fixation device as this minimizes the trauma to the extensor muscles of the foot. After external fixation combined with minimal osteosynthesis (n = 10) the patients had to stay in hospital for 6 weeks only. There was no infection at the incision of neither Steinmann-pins nor Schanz-screws and posttraumatic ostitis only in 1 case was seen. On an average only one secondary operation was necessary, a spongious bonegraft only at 3 patients. On an average the patients had the external fixation device for 5 months, bony union of the fracture was observed after 9 months. In case of external fixation without minimal osteosynthesis (n = 17) the patients had to stay in hospital for 16 weeks, 9 of them had infections at the incision of the Steinmann-pins, 9 of them developed posttraumatic ostitis with fistulae. On an average 4 secondary operations were necessary per patient and 9 patients needed a spongious bonegraft to get bony union of the fracture, which was reached on an average of 17 months.

[Treatment of infected tibial fractures and pseudarthrosis using an external fixator].

The clinical course and the results of our treatment of 18 patients with External Fixator after infection or pseudarthrosis are demonstrated. On an average of 6.1 months the patients wore the external fixator, the time of consolidation of the fracture was 17.2 months from the accident. At the date of examination - 16 months to 10 years after removal the external fixator all fractures and pseudarthroses were united. Two patients still had a fistula three years after removal of the external fixator. Three patients had slight pain in the area of the former fracture or the complication-wound; disturbance of sensibility in the area of the scar and the meshgrafts were found at 11 patients. The mobility of the knee joint was nearly free in all patients, the mobility of the ankle joint was impaired in most of them.

[Use of an external minifixator in severe open injuries of the hand].

Since January 1979 we have treated 14 patients at the 1st University Clinic of Traumatology in Vienna with the MFE described by Jaquet. The MFE was used mainly in severe open fractures of fingers and metacarpal bones. All 14 patients were examined for follow-up after a mean interval of 20 months. This method of treatment warrants minimal strain on the soft tissues while it ensures stability and optimal care of the wounds. Osseous consolidation was achieved in 13 of 14 patients; although one patient developed pseudarthrosis, he was, like 12 other patients, perfectly satisfied with the result of surgery. Only one patient was less satisfied by the result, as there was a rotational and axial deviation of 30 degrees between the fragments. However she refused operative correction, as the deviation does not interfere with her profession.
