title: The ASNIS guided system for fixation of subcapital femoral fractures.
abstract: We report a prospective, consecutive series of 84 patients with 86 subcapital femoral fractures treated by internal fixation using ASNIS cannulated screws. At 1 year the clinical and radiological failure rate was 15 per cent. The failure rate was significantly influenced by age over 75 years, dementia, and fracture displacement (P less than 0.001).
