BACKGROUND: Plate fixation has been the traditional technique for fracture repair of unstable ankle injuries with an associated lateral malleolus fracture. Recently, biomechanical and clinical data have demonstrated lag screw only fixation to be an effective alternative to plate fixation in the adult population. This comparison has yet to be studied in the adolescent or pediatric population. The objective of this study was to compare lag screw only fixation with traditional plating for lateral malleolus fractures in adolescents.
METHODS: A retrospective review was conducted of 83 adolescents with unstable oblique lateral malleolus fractures treated at a single pediatric level-1 trauma center between 2011 and 2019 with a minimum clinical follow-up until fracture union. Patients were divided into 2 surgical groups: (1) plate fixation (n=51) or (2) lag screw fixation (n=32). Radiographic and clinical outcomes and complications were measured in both groups.
RESULTS: All patients in both groups achieved our primary outcome measure of fracture union without loss of reduction. The mean surgical time for subjects treated with a plate was 15 minutes longer (64 vs. 49 min) (P=0.001) and these patients were 3.8 times more likely to have symptomatic implants (P<0.044) than subjects treated with screws. Approximately 50% of the cohort was available by phone for patient-reported outcomes at a mean follow-up of 50 months. The mean Single Assessment Numerical Evaluation scores, Foot and Ankle Ability Measure Activities of Daily Living scores, Foot and Ankle Ability Measure sports scores, and return to sports rates were similar (92 vs. 93, 98.2 vs. 98.1, 93.2 vs. 94.0, 95% vs. 86%, respectively; P>0.05) between the 2 treatment methods.
CONCLUSIONS: Lag screw only fixation is a safe and effective procedure for noncomminuted, oblique fibula fractures in the adolescent population as demonstrated by equivalent fracture healing rates without loss of reduction and similar outcome scores. Given these comparable results with the additional benefits of shorter surgical time and less symptomatic implants, lag screw only fixation should be considered as a viable treatment alternative to traditional lateral plating in the adolescent population.
LEVEL OF EVIDENCE: Level III.
