BACKGROUND

There are no formal practice guidelines for the surgical management of closed, Salter-Harris (SH) II distal tibia fractures. The purpose of this study was to survey the indications for operative and nonoperative management of this injury across pediatric tertiary care centers.

METHODS

We surveyed pediatric orthopedic surgeons at 20 tertiary care level-1 pediatric trauma centers. Surgeons were provided with 16 clinical scenarios that varied based on patient age and sex, and highlighted the following surgical indications: translation <3 mm, translation ≥3 mm, sagittal plane angulation >5 degrees, and coronal plane angulation >5 degrees. Each case's scenario and radiographs after closed reduction were presented in a randomized manner. Consensus was defined as 80% agreement, and descriptive statistics were used to summarize the results.

RESULTS

In total, 33 of 37 surgeons completed the survey (89% response rate). All surgeons took trauma call at a level-1 pediatric trauma center and had an average of 8.8 years (SD: 6.5 y) of experience. Consensus was reached in 4 of 16 scenarios. Specifically, nonoperative management was recommended for all scenarios showing <3 mm of translation after closed reduction. The majority of surgeons recommended operative management in scenarios showing coronal plane angulation after closed reduction, but none of these scenarios reached consensus. There was a near-equal split in operative and nonoperative management in 8 of 16 scenarios. These scenarios showed ≥3 mm translation after closed reduction and sagittal plane angulation after closed reduction. Surgeons with 6 to 10 years in practice were the most likely to recommend surgery, especially in the case of >5 degrees coronal plane angulation postreduction ( P <0.05).

CONCLUSIONS

There is considerable variation regarding the indications for operative and nonoperative management of closed, SHII distal tibia fractures. Consensus was reached for nonoperative management in patients with <3 mm of translation after closed reduction; however, with greater deformity consensus regarding optimal treatment was unable to be achieved. The variation in the management of distal tibia SHII fractures is significant, suggesting that perhaps clinical equipoise exists between operative and nonoperative management.
