It is the author's belief that supination injuries with tear of the talofibular ligament are the most frequent ankle ligamentous injuries encountered on the football field (Figure 4). However, the author believes that the more significant injury is the rupture of the tibiofibular ligament and interosseous ligament incurred in pronation and external rotation. (Figure 5). Twenty time-loss injuries of significance, encountered over a five year period in one football team, are presented. The mechanism of injury and the force encountered at the ankle during an interruption of the normal sequence of running and turning on the football field are presented. It is the author's opinion that rigid immobilization of the more significant injury is necessary in order to return the participant to active athletics within a reasonable length of time. It is hoped that this report will stimulate others to closely evaluate ankle injuries occurring on the football field.
The surgical technique for hindquarter amputation is described in a step-by-step manner. Since 1955 we have performed 19 such operations for eradication of malignant bone and soft tissue tumors in the pelvic, hip and upper thigh regions. Three hindquarter amputations were performed for local recurrence following initial wide excision. The overall 5-year survival rate for our 19 patients was 42.1 per cent. Malignant soft tissue tumors appear to have a much better 5-year survival rate than malignant bone tumors (60 per cent vs. 22.2 percent). We feel that surgery is still the treatment of choice. However, in the presence of proper indications, chemotherapy and radiotherapy should be added to surgery in order to prolong survival time and save lives.
This is a retrospective study of 23 infrapatellar tendon ruptures in 22 patients seen at Henry Ford Hospital from 1969 to 1980. Two of the patients had a systemic disease known to predispose to tendon ruptures, while the remainder of the tendon ruptures occurred in otherwise normal individuals as the result of either repetitive or isolated trauma.
This article describes the clinical manifestations, roentgenographic appearance, microscopic features and short- and long-term prognosis of ten cases of extraosseous osteosarcoma. The surgical technique of wedge biopsy and en bloc excision with interlocking sutures has also been illustrated. We feel that en bloc excision is the treatment of choice, and that amputation should be reserved for large tumors with major neurovascular involvement and unresectable recurrence. The overall five-year survival rate was 42.9%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
