Outcomes of Hemiepiphysiodesis in Treatment of Juvenile Hallux Valgus (Systematic Review)

Category: Bunion Introduction/Purpose: The aim of this study was to evaluate the efficacy of percutaneous hemiepiphysiodesis for JHV by investigating the available literature on the procedure. Methods: The literature search was conducted by using the following bibliographic electronic databases: EMBASE, MEDLINE, and PubMed.gov. Study screening at all stages was completed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) criteria. The Methodological Index for Non-Randomized Studies (MINORS) scale was used to evaluate the quality of included studies. Data on patient characteristics, radiological and clinical outcomes, and notable complications were also collected. Results: Of the 91 studies identified by our search strategy, 4 met the inclusion criteria. The identified studies included 62 patients and 109 feet. The mean hallux valgus angle (HVA) improved preoperative to postoperative at a range of Δ3.45 to Δ5.5. The mean intermetastartal angle (IMA) improved preoperative to postoperative at a range of Δ2.2 to Δ4.0. The mean HVA progression per month improved from preoperative to postoperative at a range of Δ0.07 degrees/month to Δ0.17 degrees/month. The mean IMA progression per month improved from preoperative to postoperative at a range of Δ0.046 degrees/month to Δ0.067 degrees/month. Of the studies that reported a mean American Orthopaedic Foot and Ankle Society (AOFAS) score or a mean Hallux Metatarsophalangeal Interphalangeal Scale (HMIS), there was an improvement at a range of Δ16.5 to Δ36. Conclusion: Percutaneous Hemiepiphysiodesis can serve as an effective procedure for treating Juvenile Hallux Valgus.
