Minimally Invasive Percutaneous Extended Plantar Limb (Modified) Chevron Osteotomy for Hallux Valgus Correction
Introduction: This video demonstrates percutaneous correction of severe hallux valgus in a patient with a hallux valgus angle of 46°, an intermetatarsal angle of 20°, a distal metatarsal articular angle of 30°, an incongruent joint, and a crossover deformity of the second toe.
Methods: Surgical correction consists of percutaneous extra-articular reverse-L proximal chevron osteotomy of the first metatarsus, with the plantar arm longer than the vertical arm, stabilization with the use of a bioabsorbable screw, and percutaneous osteotomy of the proximal phalanx. The third presentation of the surgical procedure involves a sawbone demonstration of the percutaneous osteotomies. The crossover deformity of the second toe is corrected via percutaneous plantarization osteotomy of the proximal phalanx base, dorsalizing osteotomy of the intermedial phalanx, percutaneous tenotomy of the extensor longus, dorsal capsulotomy of the metatarsophalangeal joint, and flexor longus and brevis tenotomy using a plantar approach. The fifteenth postoperative radiograph and clinical photograph are shown.
Conclusions: This procedure allows for adequate percutaneous management of severe hallux valgus deformity.
