Short Term Behaviour of Fixed-Loop Cortical Suspension System Used for Surgical Treatment of <i>Hallux valgus</i>

Abstract

Hallux valgus represents an acquired foot deformity characterized by lateral deviation of the hallux and medial deviation of the first metatarsal. Pain during gait is the main complain and is caused by reduction of plantar pressure under the first ray leading to insufficiency of the first ray and overload of the lesser rays. Treatment can be nonoperative or surgical with more than one hundred surgical techniques described so far. The scope of this study was to assess the short term reliability and stability of fixed loop suspension systems used for surgical treatment of this pathology using radiological evaluation of hallux valgus angle and the intermetatarsal angle. Our results show good stability of the reduction and good reliability of the suspension system, with a six months follow-up. Only one specific complication (failure of the wiring material) is highlighted by our conclusions and the need for biomechanical testing in controlled laboratory studies.

Review of current hallux valgus management options

“…A modern wave of techniques has reintroduced this concept by applying a dynamic, flexible fixation of a corrected IMA using high-strength suture wires secured on bone with metallic buttons or anchors (metallic or biodegradable). Also, variations of these procedures can be used for tarsometatarsal stabilization in conjunction with osteotomies for bone correction [48][49][50]. The results seem promising but a longer followup and biomechanical testing are needed for a comprehensive recognition as a reliable treatment strategy.…”
