The extensor digitorum brevis island flap: possible applications based on anatomy.

In the past few years, the proximally based extensor digitorum brevis island flap has been recognized as a useful method in the reconstruction of the lower extremity. The major goal of this study, which was performed in 16 cadavers, was to show the possible application of the extensor digitorum brevis island flap based on its anatomy. The vascularization and morphology of the muscle were also studied. We are able to show that, with sufficient mobilization of the vascular pedicle, the extensor digitorum brevis easily can reach both the lateral and the medial malleoli. In most cases, the island flap even reaches the Achilles tendon, the posterior aspect of the heel, and the lower to middle part of the anterior crural region. The vascular supply of the extensor digitorum brevis muscle shows a great consistency, with the lateral tarsal artery being the dominant supply of the muscle. The mean surface of 27 cm2 allows coverage of small to medium-sized defects.

[Quality assurance in surgery].

Since 1990 the Surgical Department of the Kantonsspital Schaffhausen has been taking part in a quality assurance program organized by the "Bundesland Baden-Württemberg". The traceroperation "appendectomy" will be used to demonstrate the principle of quality assurance and our results for the years 1991 and 1992 will be presented.

[Loss of the extremity despite patent vascular reconstruction].

This retrospective study concerns 8 patients, who had successful vascular reconstruction for ischaemia of a lower extremity but nevertheless needed lower or upper leg amputation. The analysis shows that in four patients (one of them diabetic) misjudgement was the cause of failure. The other four patients all had diabetic angiopathy. No misjudgement or wrong decision was found in the analysis of their case. Here the failure is interpreted as the fatal destiny of a seriously damaged microangiopathic extremity.

[Treatment of an infected inguinal wound following vascular reconstruction with a sartorius muscle flap].

Infection or breakdown of a wound in the groin is a dreaded complication in vascular surgery. On 8 patients with such impending or declared wound complications, a distally pedicaled sartorius muscle-flap was performed immediately after wound debridement, to cover the autologeous or alloplastic vascular graft. In all but one case the groin healed promptly. In 6 cases the vascular repair remained patent.

[Muscle-flap plasty in fractures of the tibial pilon].

It is not rare in fractures of the distal lower leg, that precarious soft-tissue conditions compromise the outcome of early osteosynthesis. Because of oedema and haematoma the wound is widely split open and its primarily closure is perilous. In such a situation the stabilized fracture can be covered primarily with a local muscle-flap, such as extensor digitorum communis or peronaeus brevis. In the last 2 years we have chosen this solution in 6 cases.

[Burn mortality and morbidity: experience of the burn center in Zürich from 1967 to 1977].

Ten years of burn treatment in a burn center are compared to the ten years prior to 1967: --Survival has increased markedly, due to aggressive local treatment with débridement, topical ointments, biologic dressings, and rapid closure of wounds. --Functional and cosmetic results have improved since tangential excision and immediate autografting are routinely performed. --Favourable results with shorter duration of hospitalization are obtained if doctors and nurses can acquire and apply their knowledge in many cases as is possible in a burn center.

[Experiences with the Sarmiento-cast].

The patella-tendon-bearing cast described by Sarmiento was used in the treatment of 96 tibial fractures. Full weight-bearing was permitted even if the fractures were completely unstable and had a marked tendency to shorten. Only in one case weight-bearing led to a dislocation of the fragments. Specific complications were not seen. It was evident that the PTB-cast was most advantageous to the patient in comparison with a conventional cast and sometimes even in comparison with an osteosynthesis, which does not tolerate weight-bearing. To integrate the Sarmiento-cast in the routine of a small or middle sized hospital, we recommend to observe the following rules: 1. The cast is not applied immediately after the accident, but after one to three weeks of conventional conservative treatment. 2. It is made by two specially trained doctors. 3. The controls of the out-patients are performed in the hospital and not delegated to the family doctor.

[Gas gangrene. The files of the Swiss Accident Insurance Company 1963-1975].

The clinical histories of 28 cases registered as gas gangrene by the Swiss National Accident Insurance (Schweizerische Unfallversicherungsanstalt) from 1963 to 1975 are reviewed. According to the classification of Altemeier (1. gas gangrene, 2. clostridial cellulitis, 3. simple contamination of a wound by Clostridium, and 4. gaseous infection without Clostridium) only 5 cases were assignable to group one (1 survivor), 2 cases to group two, 9 to group three and 9 to group four. Typical cases from each group are discussed to illustrate the advantages of this classification, the dangers of treatment based on wrong diagnosis, and the necessary prophylaxis. The more serious prognosis in gas gangrene in comparison to the other groups is emphasized.

[Arthroscopic knee diagnosis in the non-specialized surgical department].

From the review of 200 cases we conclude that arthroscopy is not only indispensable to the specialized knee surgeon, but also very useful to the general surgeon in a smaller hospital who has to deal with the routine knee problems. The method allows to establish the diagnoses in almost any situation and helps to avoid unnecessary delays and unnecessary operations. Arthroscopy needs general anaesthesia, but when the diagnosis calls for surgical treatment, the operation is performed immediately under the same anaesthesia. The knee examination by arthroscopy is neither time-consuming nor technically or financially demanding. Complications are extremely rare.
