Percutaneous basal closing wedge osteotomy for hallux valgus deformity.

OBJECTIVE: This article describes the percutaneous technique of a minimally invasive basal closing wedge osteotomy for correction of hallux valgus. INDICATIONS: This procedure allows correction of severe deformity with a minimally invasive approach. CONTRAINDICATIONS: No specific contraindication; a fusion would be preferred for an arthritic tarsometatarsal or metatarsophalangeal joint. SURGICAL TECHNIQUE: The surgical technique is based on the use of burrs specifically adapted for foot surgery. A basal closing wedge osteotomy is performed and fixed percutaneously. Each step is controlled under fluoroscopy. POSTOPERATIVE MANAGEMENT: A postoperative heel shoe is prescribed for 6 weeks with crutches. The foot is elevated during the first 2 weeks. Impact is forbidden for 3 months.
RESULTS: The authors report good and excellent results with an average correction of the hallux valgus angle of 26° and an intermetatarsal angle of 8.2°.
