The Minimally Invasive SERI Osteotomy for Pediatric Hallux Valgus

: Hallux valgus (HV), one of the most common forefoot pediatric pathologies, is characterized by lateral deviation of the big toe and medial displacement of the first metatarsal bone. Different surgical techniques have been described to correct the deformity, but no consensus has been reached regarding the best surgical option. The aim of this retrospective study was to report the results of the SERI technique in 58 pediatric HV of 45 consecutive patients. Pre- and postoperative VAS, AOFAS score, HVA, IMA and DMAA were collected. Preoperatively 3 patients (5.2%) had a mild deformity, 52 patients (89.6%) had moderate deformity and 3 patients (5.2%) had severe deformity according to Coughlin et al. Mean VAS score decreased from 5.2 ± 2.2 preoperatively to 0.8 ± 0.4 postoperatively. Mean AOFAS score improved from 68.1 ± 6.8 (range 59-75) preoperatively to 96.3 ± 3.2 (range 88-100) postoperatively, mean HVA reduced from 28.4° preoperatively to 13.2° postoperatively, mean IMA decreased from 15.2° preoperatively to 9.5° postoperatively (p < 0.01); mean DMAA decreased from 13.7° preoperatively to 8.2° postoperatively (p < 0.01). SERI technique showed satisfactory results when treating mild to severe pediatric HV deformity. No major complications were reported.
