BACKGROUND: The purpose of this study was to evaluate the operating room (OR) intervention rates and quality of fracture reductions for pediatric diaphyseal both-bone forearm fractures performed by orthopaedic residents relative to the academic year. OR intervention was defined as any procedure performed in the OR, including closed reduction and casting, and was used to identify fractures that required secondary intervention after initial closed reduction performed by an orthopaedic resident in the emergency department.

METHODS: A retrospective analysis identified pediatric patients presenting at our institution with both-bone forearm fractures from July 2010 to June 2016. Emergency-room sedation time, highest experience of orthopaedic resident documented to be present at the time of sedation (in postgraduate months), and frequencies of OR intervention were obtained by chart review. Fracture characteristics were determined by radiographic review. Immediate postreduction radiographs were used to measure cast indices, and adequacy of reduction was determined by postreduction angulation and translation.

RESULTS: During the time period studied, 470 both-bone forearm reductions under sedation were performed by an orthopaedic resident at our institution. Of these, 41 fractures (41 patients) required 42 OR interventions (40 involved surgical fixation and 2 were repeat closed reductions). The academic year was divided into quartiles. The April to June quartile had the highest overall percentage of OR intervention (10.6%), followed by July to September (8.6%); however, there was no significant difference between quartiles in the percentages of reductions that needed OR intervention (P=0.553). There was also no correlation between the experience level of the resident performing the reduction (based on postgraduate months) and the frequency of OR intervention (P=0.244). The anteroposterior (AP) and lateral reduction grades did not vary based on quarters (P=0.584; 0.353). The ability to obtain adequate reduction and the rate of unacceptable cast index were also not significantly different between quarters (P=0.347 and 0.465).

CONCLUSIONS: We found no significant difference in rates of OR intervention or the quality of reduction for pediatric both-bone diaphyseal forearm fractures treated by orthopaedic residents relative to the academic year.

LEVEL OF EVIDENCE: Level III-comparative cohort study.
