    Notizen: Summary The influence of immobilization on patellar tendon autograft healing was investigated in 12 sheep with replaced posterior cruciate ligaments of the knee (PCLs). In one group achillotomy immobilized the operated knee joint. In another group initial reduced weightbearing was obtained by hanging the sheep in a special trapeze. In the third group no protection at all was given to the operated knee. The sheep in this group went within 8 weeks from partial use of the operated leg to unrestricted weightbearing and mobility. Biomechanical testing 16 weeks after the operation demonstrated a considerable decrease in the maximum force, ligament stiffness, and strain values in the achillotomy group, as well as an increase in posterior laxity. The best data were observed in the no-protection group. This study demonstrates the negative effect of immobilization on autograft healing in a sheep PCL model. Even early in the healing process tissue may be extremely sensitive to stress and strain.

    Notizen: Summary In the pelvic region three major compartments (gluteus medius-minimus compartment, gluteus maximus compartment, and iliopsoas compartment) can be distinguished from the smaller compartment of the tensor fasciae latae muscle. Pelvic compartment syndromes are rare. A clear history of trauma is often lacking. Association with drug and alcohol abuse is common, as is the association with the widespread use of anticoagulant therapy. From 1982 to 1990 six patients with acute buttock compartment syndrome were treated in the Department of Trauma Surgery of Hannover Medical School. In five patients fasciotomy of the gluteal compartment was performed. Two patients with a compartment syndrome secondary to necrotizing fasciitis died of septic multiple organ failure. The mean follow-up of the four other patients was 29 months (7–48 months). Three of these four patients revealed a decrease of gluteal muscle volume. Ergometric tests showed a decrease in gluteal muscle force in all patients.

    Notizen: Abstract 176,177Ir were produced by irradiation of141Pr with40Ar. β-delayed γ-rays of176,177Ir were observed for the first time. From γγ-coincidence data decay schemes could be constructed. A new half-life of177Ir was obtained yielding t1/2=30 (2) s. α-branching ratios of 3.1(6) % for176Ir and 0.06(1)% for177Ir were measured.
