Effect of sesamoid position on long-term results of hallux abducto valgus surgery.

Radiographic parameters for 70 patients that underwent hallux abducto valgus (HAV) surgery were evaluated with emphasis on the tibial sesamoid position. The preoperative and postoperative sesamoid positions were analyzed. Soft tissue bunionectomies, metatarsal head and base osteotomies, and first metatarsocuneiform arthrodesis are procedures that were included in this evaluation. The inadequate relocation of the sesamoids, along with other standard parameters, were then correlated with recurrence of hallux abducto valgus and metatarsus primus adductus. The surgical relocation of the sesamoid apparatus is discussed, including both an intracapsular and extracapsular release. Possible indications for fibular sesamoidectomy are suggested. Effects of sesamoid position on the long-term results of HAV surgery are presented.
