[Clinical aspects and therapy of intestinal non-rotation in adults]. / Klinik und Therapie der intestinalen Nonrotation beim Erwachsenen.

The intestinal non-rotation is a rare fetal disorder of the gut torsion. Its manifestation is very rarely seen in the adult, either in form of a volvulus of the midgut or ileocecal with an acute onset, or as chronic recurrent abdominal pain. Each diagnostic or therapeutic delay increases the risk of strangulation and may end as an abdominal disaster. We describe three own cases and we try to elucidate the diagnostic and therapeutic problems. Our proceeding: In the acute symptomatic form the explorative laparotomy with a consequent staging of the abdominal situs is the safest way to get an exact diagnosis. Therapeutically the procedure described by LADD is the best torsion prophylaxis; the ascending colon is sawn to the descending colon. Due to a paratopia, the appendectomy is recommended. In the chronic forms the contrast enema and the gastrointestinal barium study are the main diagnostic procedures. In the operation described by Fitzgerald and the ascending colon and the mesentery of the small bowel are--after incision of the common mesentery--fixed at their anatomical site.

[Bone and joint transplantation. Alternatives to bridging segmental bone defects and a model for allogenic bone transplantation]. / Knochen- und Gelenktransplantation. Alternativen zur Uberbrückung segmentaler Knochendefekte und ein Modell zur allogenen Knochentransplantation.

Fresh allogeneic diaphyseal bone segments were transplanted into 12 dogs. We attempted to improve the immunogenity and incorporation of the bone segments through "graft manipulation" with and without immunosuppression. Through clinical and radiological study during the 20-week experimental period, we observed transplant healing with differing structural phenomena. After autologous knee joint replantation in 4 dogs and allogeneic transplantation in 2 dogs (with and without revascularization and immunomodulation with Cyclosporin A) we present a canine model to investigate all open questions about the transplantation of allogeneic, fresh joints (i.e. transplant biology, immunology, and vitality).

[External hypertension syndrome of the patella. Its significance in the recognition of arthrosis]. / Syndrome d'hyperpression externe de la rotule (S.H.P.E.). Son intérêt pour la connaissance de l'arthrose

Some chondromalacia are caused by an hyperpressure on the lateral articular facet of the patella. The authors describe the clinical signs and the radiological findings in this condition. It is due to a retraction of the lateral patellar ligament. They have operated on 133 cases and reviewed 115 knees. After a simple section of the lateral patellar ligament, results were satisfactory in 80 percent of the cases. Biopsies of the malacic cartilage were performed and pathological changes were described.
