Outcome following temporal delay in fracture fixation of the femoral neck is primarily affected by osteonecrosis of the femoral head, whereas restriction of movements, shortening, and premature physeal closure has no significant influence. There was a significant correlation ( r = 0.52) between development of osteonecrosis and delayed fracture fixation of >10 days ( P = 0.016) and open reduction ( P = 0.016). Three (14.3%) patients had osteonecrosis of the hip, which was significantly related to poor outcome ( r = 0.495 P = 0.022). ResultsĪll fractures united at a mean duration of 12 (range 10.6–14) weeks. Patients were followed for a mean of 81 (range 66–129) months. Results were assessed on the basis of modified Ratliff criteria.

Patients were allowed full weight bearing after 12–18 weeks. Extraphyseal fixation was done using partially threaded cannulated cancellous screws after closed or open reduction. Radiological and functional evaluation was done for delayed fixation (>24 h) of displaced fractures in the femoral neck in 21 children (21 hips) treated over 11 years. Also, the role of capsular decompression in initial management needs to be elucidated. Prospective evaluation of results after delayed fixation of femoral neck fractures in children beyond the first 24 h is not reported in the literature and requires evaluation to increase our understanding of the procedure and improve fixation methods. Complications that develop after femoral neck fracture in children-especially osteonecrosis-have been retrospectively attributed to inadvertent delayed fixation and fracture type.
