[Correlative study between length of first metatarsal and transfer metatarsalgia after osteotomy of first metatarsal].

Objective: To evaluate the correlation between the length of first metatarsal, hallux valgus angle (HVA), intermetatarsal 1-2 angle (IMA1-2), plantar appearance, sesamoid position and postoperative 2-5 transfer metatarsalgia.

Methods: Retrospective analysis was performed for the clinical data of 375 cases (626 feet) undergoing osteotomy of first metatarsal with mini-incision. All cases were examined radiographically via weight-bearing and lateral views.
