Importance of postoperative sesamoid reduction on the outcomes of proximal chevron osteotomy for moderate to severe hallux valgus deformity

Proximal metatarsal chevron osteotomy combined with a distal soft tissue procedure has been widely used to correct moderate to severe hallux valgus deformities. Previous studies have reported excellent outcomes with this procedure and high rates of patient satisfaction [1 –6]. However, there may be recurrence of the hallux valgus deformity after proximal metatarsal chevron osteotomy. The recurrence of the hallux valgus deformity is due to various reasons, including incomplete release of the adductor hallucis tendon, insufficient imbrication of the medial capsule, i ncreased distal metatarsal articular angle, insufficient correction of the metatarsus primus varus, excessive first ray mobility, and incomplete reduction of the sesamoid [7,8].
