The Endolog system for moderate-to-severe hallux valgus

Purpose. To report the midterm outcome of the Endolog system for correction of moderate-to-severe hallux valgus. Methods. 23 women and 2 men (33 feet) aged 35 to 80 (mean, 52) years underwent minimally invasive surgery for moderate (n=25) and severe (n=8) hallux valgus using the Endolog system. The hallux valgus angle (HVA), the intermetatarsal angle (IMA), and the proximal articular set angle (PASA) were measured on radiographs. The feet were also assessed based on the American Orthopaedic Foot and Ankle Society (AOFAS) scale. Results. The mean follow-up duration was 18.2 (range, 12–36) months. The mean HVA, IMA, PASA, and the mean AOFAS score improved significantly after surgery (all p<0.0001). Periosteal reaction was noted by week 4, and callus formation after 3 months. There were no delayed or non-union or other complications. Conclusion. The Endolog system achieved good outcome for moderate-to-severe hallux valgus.
