Delayed treatment of supracondylar elbow fractures in children.

ABSTRACT

BACKGROUND: Supracondylar fractures are the most common elbow fractures in children and are usually treated on an emergency basis, using percutaneous pinning. However, the treatment is often delayed in areas where healthcare resources are scarce. HYPOTHESIS: Delaying treatment does not influence the perioperative complication rate. MATERIALS AND METHOD: We retrospectively reviewed the medical charts of 89 children aged 2 to 15 years in whom surgery for extension-type supracondylar elbow fractures was delayed by more than 48 hours. The 53 boys and 36 girls with a mean age of 6 years 9 months had severe fracture displacement (28 stage III and 61 stage IV according to Lagrange and Rigault classification scheme). Mean time to treatment was 4.5 days (range 2-17 days). Open reduction and crossed K-wire fixation via the posterior approach were performed in all 89 patients. Postoperative complications and sequelae were collected. Functional outcomes were evaluated using Flynn's criteria. RESULTS: Outcomes were satisfactory in 74 (83.2%) of patients. Postoperative complications occurred in 13 (14.6%) patients and consisted of surgical site infection (n=7, 7.8%), iatrogenic nerve injury (n=3, 3.4%), and reoperation (n=3, 3.4%). At last follow-up after a mean of 5 months, three (3.4%) patients had cubitus varus and one had a recurrent fracture due to massaging. Elbow motion was limited in 11 (12.4%) patients. No case of compartment syndrome was recorded. DISCUSSION: Despite an average time to surgery of 4.5 days, the outcome was satisfactory in 83% of cases. Delayed treatment was not associated with an increased rate of perioperative complications. LEVEL OF EVIDENCE Level IV, retrospective study.
