Abstract

From 1971 to 1985, 369 athletes presented to us with stress fractures. Of these patients, 10 (37) were treated for development of delayed unions or non-unions. Twenty-seven of the patients were male and 10 were female. Their mean age was 23.1 years (range, 17 to 39). About half of the athletes were involved in endurance sports. The diagnostic criteria for a delayed union or nonunion were clinical and radiological evidence. There was a diagnostic delay of about 3.5 months in the series. Plain radiographs, tomography, and isotope scans were used in the diagnosis. Special radiographic views were also used. In 15 cases (10 hallux sesamoid bone fractures, 1 midtibial shaft fracture, 1 metatarsal V base fracture, 1 tarsal navicular fracture, 1 olecranon fracture, and 1 proximal tibial shaft fracture) nonoperative treatment was used. Operative treatment was used 22 times (5 sesamoid fractures, 5 midtibial fractures, 5 metatarsal V base fractures, 3 tarsal navicular fractures, 3 olocranon fractures, and 1 proximal tibial shaft fracture). Results were good or excellent in 32 cases (86.5), moderate in 4 cases, and poor in 1 case. - Verf.-Referat -
