Results of operative treatment of avulsion fractures of the iliac crest apophysis in adolescents.

Abstract

Avulsion fracture of the iliac crest apophysis is a rare condition that commonly occurs in adolescent athletes. Conservative treatment for this injury can produce excellent functional outcomes. However, the rehabilitation process requires a rather long immobilisation period. This study aimed to evaluate the use of cannulated screws for fixation of avulsion fractures of iliac crest apophysis. Ten patients with avulsion fractures of iliac crest apophysis were treated by open reduction and internal fixation using cannulated screws. The mean age of patients was 14.6 years (range, 13-15 years). The mean intraoperative blood loss was 14.9 ml (range, 10-25 ml). The mean operative time was 40.3 min (range, 33-52 min). The mean follow-up period was 11.2 months (range, 6-20 months). At the 4-week follow-up, all patients returned to previously normal activity without pain and had no evidence of lower extremity muscle weakness. At the final follow-up, all patients resumed their athletic activity without any complications. Open reduction and internal fixation for the treatment of avulsion fracture of iliac crest apophysis can be recommended for patients requiring rapid rehabilitation.
