BACKGROUND: Controversy exists regarding the treatment of length unstable pediatric femoral shaft fractures. The purpose of this study was to investigate the outcomes of skeletally immature children with length unstable femur fractures treated with titanium elastic nails (TENs). METHODS: A retrospective review was conducted on all patients with femoral shaft fractures at a tertiary care pediatric hospital from April 2006 to January 2018. Patients with femoral shaft fractures treated with TEN and minimum 6 months follow-up were included. Exclusion criteria were age 11 years or above, weight >50 kg, pathologic fracture, and neuromuscular disorders. Femur fractures were categorized into 2 groups: length unstable (spiral, comminuted, or long oblique fractures) versus length stable (transverse and short oblique). Complications and reoperations were compared between the groups. RESULTS: A total of 57 patients with 58 femoral shaft fractures were included. The mean age was 5±2 (1 to 11) years and mean follow-up was 20.4±18.1 (6.0 to 81.2) months. The mean weight was 22.9±7.7 (11.0 to 40.5) kg. There was no difference in age (P=0.32), weight (P=0.28) or follow-up length (P=0.57) between patients with length unstable fractures and those with length stable fractures. A total of 32/58 (55%) fractures were length unstable and 26/58 (45%) were length stable. Mean time to union was 4.6 months, and there was no significant difference in mean time to union between the 2 groups (P=0.71). Thirty-one complications occurred in 27 patients. There was no difference between groups in the incidence of major complications requiring revision surgery (P=0.68) and minor complications that did not require revision surgery (P>0.99). CONCLUSIONS: In children with femoral shaft fractures treated with TEN, there was no difference in the incidence of complications or reoperations between those with length unstable fractures and those with length stable fractures. TEN are a safe and effective choice for operative fixation of length unstable femoral shaft fractures in children. LEVEL OF EVIDENCE: Level III-retrospective comparative study.
