Hallux valgus correction with a new percutaneous distal osteotomy: Surgical technique and medium term outcomes.

BACKGROUND

Many procedures and different osteotomies have been described for percutaneous hallux valgus correction. Percutaneous techniques may lead to reduced morbidity, surgery, and recovery time. The aim of this study is to evaluate the clinical and radiographic outcome of a new percutaneous procedure (PBS-Percutaneous Bianchi System).

METHODS

Fifty-eight cases were treated with Percutaneous Bianchi System procedure for correction of mild, moderate or severe hallux valgus deformity. All patients were clinically assessed preoperatively and then followed up by weight-bearing x-rays, AOFAS (American Orthopedic Foot and Ankle Score), VAS (Visual Analog Scale) pain score, and patient satisfaction.

RESULTS

AOFAS scores improved from 28.6 at the preoperative assessment to 91.7 at the latest follow-up. The VAS pain score improved from 6.7 before surgery to 0.6 at the latest follow-up. The mean Hallux valgus angle (HVA), Intermetatarsal angle (IMA) and Distal metatarsal articular angle (DMAA) significatively decreased from the preoperative assessment to the latest follow-up.

CONCLUSIONS

The PBS technique is a safe, reliable, and effective procedure for the correction of symptomatic mild-to-severe hallux valgus.
