Percutaneous basal closing wedge osteotomy for hallux valgus deformity; [Perkutane basale Closing-Wedge-Osteotomie bei Hallux-valgus-Deformität]

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°. © 2021, Springer Medizin Verlag GmbH, ein Teil von Springer Nature.
