Abstract

Objective: The optimal management of pediatric type II supracondylar humerus fractures (SCHFs) is debated. We conducted a systematic review comparing outcomes and complications of nonoperative versus operative management to aid decision-making and inform future research.

Methods: We searched PubMed, Web of Science, MEDLINE, and CINAHL from their inception until February 7, 2024, including studies on pediatric patients (<18 y) with any type II SCHF, provided they compared operative to nonoperative care and were in English. The quality of articles was evaluated using the Methodological Index for Non-Randomized Studies Scale.

Results: Out of 417 studies reviewed, 7 met the inclusion criteria. These studies involved 1446 patients (mean age: 4.9 y; mean follow-up: 5.0 mo), comparing operative (n = 427) and nonoperative (n = 1019) treatments. Functional outcomes such as carrying angle, Baumann angle, elbow range-of-motion, and patient satisfaction were similar across treatment groups. Nonoperative management showed a higher incidence of residual sagittal deformity (14.1% vs 0.0%; P < 0.0001) and a treatment failure rate of 8.9% to 20.6%, necessitating surgical intervention. Factors prompting operative care included rotational deformity, varus/valgus misalignment, and a shaft-condylar angle below 30 degrees.

Conclusion: Nonoperative treatment of type II SCHF is linked with higher rates of residual sagittal deformity and a notable failure rate requiring subsequent surgery. Both treatment strategies showed similar functional outcomes and patient satisfaction. Further research should focus on identifying anatomic criteria predictive of nonoperative treatment failure.

Level of evidence: Level III-systematic review.
