Purpose:To evaluate and analyze the incidence, clinical features, cause and surgical outcomes of iatrogenic hallux varus deformity after hallux valgus surgery.
Material and Methods :Twenty-six Hallux varus deformities after hallux valgus surgery were evaluated. Clinical tolerability, patient’s satisfaction and the main causative factor for varus deformity were evaluated. Radiologically, we measured the 1st intermetatarsal angle and hallux valgus angle on pre- & postoperatively.
Results:10 cases of 26 varus deformities were clinically intolerable. The patients complaint of mainly cosmetic and shoe fitting problems rather than pain and the main cause of deformities were over-correction of 1st intermetatarsal angle. Radiologically, the average 1st intermetatarsal angle was 2.4 degrees and the hallux valgus angle was -9.2 degrees. After varus correction surgery, the average follow up were 17 months and the average 1st intermetatarsal angle was 2.3 degrees and the hallux valgus angle was 2.7 degrees. The average score of AOFAS Hallux Metatarsophalangeal-Interphalangeal Scale was 91 points.
Conclusions: The hallux varus deformity after hallux valgus surgery came from mainly overcorrection of 1st intermetatarsal angle. The management composed of just observation, tendon transfer and fusion, and each method could get satisfactory results with appropriate indication.
