Abstract
INTRODUCTION: The management of paediatric femoral fractures continues to spark debate in published literature, with poor quality evidence guiding current guidelines on the optimum treatment in children. Many centres report excellent results for both elastic intramedullary nailing and plate fixation of diaphyseal femoral fractures. This study aimed to investigate the outcomes of femoral fractures treated with elastic nail fixation versus those treated with plate fixation in a tertiary children's trauma unit, and discuss the advantages and disadvantages of each technique. MATERIALS AND METHODS: A retrospective review of all femoral fractures undergoing fixation at a level one paeditric trauma and tertiary referral unit, between 1(st) April 2009 and 30(th) April 2017, was performed.Clinical notes and radiographs were reviewed to determine patient demographics and injury, operative and hospital stay data. Radiological union, defined as bridging callus present on at least three out of four cortices on orthogonal radiographs, was determined at 12 weeks. Outcomes were determined using the Flynn Criteria. Patients were followed up for a minimum of 2 years. Data was statistically analysed, and a p value < 0.05 was considered significant. RESULTS: There were a total of 28 patients- 14 in each treatment group. Patients undergoing elastic nail fixation were significantly older than plate fixation (9.7 ± 1.9 Vs 7.7 ± 1.8; p = 0.008). A male preponderance was noted (21/28), with no difference between groups (10 Vs 11; p = 1.00). Plate fixation demonstrated a tendency towards shorter length of stay (6.3 ± 2.1 Vs 7.8 ± 3.0; p = 0.134), earlier radiological union at 12 weeks (14 Vs 10; p = 0.098), lower postoperative analgesia requirements (0.82 ± 0.45 Vs 1.12 ± 0.97; p = 0.200), and better outcomes, as determined by the Flynn criteria. CONCLUSIONS: In the authors opinion, plate fixation is a safe, effective alternative to elastic nail fixation with equivocal outcomes as determined by the Flynn Criteria. Plate fixation may offer advantages in shorter length of stay, reduced postoperative pain and earlier weightbearing. Further large scale, prospective research is required to determine whether these are borne out in practice.
