The natural course of ankle fractures was studied in 143 patients treated by closed methods. The average time elapsing from fracture to follow-up was 29 years. Eighty-two per cent had no radiographic signs of arthrosis; 83 per cent were free of symptoms. The most common fracture, supination eversion Stage II (49 cases), gave rise to minimal signs of arthrosis in only one patient, who had moderate symptoms. The suggestion that all ankle fractures must be perfectly reduced is not supported by the findings of the present study.
Thirty patients with osteochondritis dissecans of the ankle have been followed up for an average of 21 years. The histories and radiographs were revi#{231}wed, and it was found that most patients had only minor radiographic changes and symptoms. Two patients had developed osteoarthritis but in only one was this severe Osteochondritis dissecans in the ankle thus seems to differ from the same lesion in the knee where late osteoarthritis often occurs. Two lesions were located on the joint surface of the distal tibia, a site not previously reported. The natural history of osteochondritis dissecans of the ankle has not been widely studied, although the results of its treatment have been extensively reported osteochondritis dissecans of the talus were found. Of these, 30 patients were still living in the city and were
The sex- and age-specific incidence has been calculated for ankle fractures from the first part of the 1950s and compared with the 1980s, a 30-year interval. The fractures were also classified according to Lauge-Hansen. Altogether 1784 fractures were found. During that time interval ankle fractures had become more common, particularly those with extensive skeletal involvement, such as the stage IV supination-eversion fractures, which today have an incidence pattern more typical of a fragility fracture in elderly women.
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.
