The diagnosis of an acute partial tear of the anterior cruciate ligament was made in 56 patients who did not undergo surgical repair. After a period of up to 5 years, 39 returned for follow up evaluation. They were divided into three groups according to clinical analysis of the knee and the Lysholm-Gillquist score. Our aim was to determine their long term functional limitations. 56% had progressed to anterior cruciate ligament deficiency at the time of follow up. This came about not only after resuming sporting activities, but also occurred in those who were not so active. Our results suggests that a partial tear leaves an irreversible defect which may progress to a complete tear, especially in young athletes engaged in active sport.

Two cases of percutaneous transfemoral embolization of facial hemangiomas and arteriovenous (AV) malformations are reported. In both cases, Ivalon shavings were injected through a percutaneously placed catheter to permanently occlude peripheral feeders of the AV malformation. In one case, because of the size of the large venous sacs associated with the malformation, a steel coil was introduced to form a baffle, over which several additional strands of surgical silk were introduced to obliterate these sacs. These cases emphasize the need for embolization of small feeding arteries to prevent recurrence by collateral channels. To achieve this, specific-sized emboli are necessary; Ivalon is a suitable embolic material.

A 64-year-old female patient has been suffering from sinus histiocytosis with massive lymphadenopathy (SHML) for 2 years. After 12 months of illness, the patient developed swelling and pain in various skeletal regions. Scintigraphic, radiological and CT imaging revealed multiple osseous lesions. Subsequent biopsies yielded the histomorphological findings typical for SHML. After operative resection of the left cuboid, which was the most painful region during walking, the defect was filled with an autologous bone transplant. At this time no other osteolytic region was treated surgically, because the patient had first to undergo ENT treatment.
