Treatment of hallux rigidus by minimally invasive resection of the dorsal osteophytes, synovectomy and resection of the dorsal part of the metatarsal head. Hallux rigidus grades II and III CONTRAINDICATIONS: End-stage osteoarthritis of the first metatarsophalangeal joint with beginning ankylosis. Osteophytes around the metatarsophalangeal joint are removed using a 1 cm incision dorsomedial, approximately 3 cm proximal of the joint space. The dorsal third of the metatarsal head is resected with a burr to improve dorsiflexion. The extent of bone resection is checked with an image intensifier. Loose bone fragments removed with a rangeur. An arthroscopy can be performed to check the completeness of bone resection, the irrigation of the joint and, if needed, to extend the synovectomy. Removal of the sutures after 2 weeks. Depending on pain, the patient can change from the postoperative shoe to a normal soft, comfortable and wide shoe after 1-2 weeks. Nonsteroidal drugs can be prescribed as needed. Active and passive mobilization of the metatarsophalangeal joint is also recommended. The technique allows a soft-tissue-preserving resection of the osteophytes and a partial resection of the metatarsal head. The main advantages are limited soft-tissue trauma and rapid rehabilitation. In all, 21 women and 17 men with hallux rigidus stages II and III (Vanore) underwent surgery. Minimum follow-up was 12 months. In 1 patient, injury of the extensor hallucis longus tendon was observed. Two patients underwent revision surgery. One patient was converted to a metatarsophalangeal fusion, while another patient received a resection arthroplasty. At the latest follow-up, the AOFAS (American Orthopaedic Foot & Ankle Society) score averaged 88.7 points.
