Abstract

Checkrein deformity is characterized by flexible plantar flexion contracture of the interphalangeal joint and flexible extension contracture of the metatarsophalangeal joint of the hallux. It occurs due to entrapment of the flexor hallucis longus in the callus formation at the fracture site or within scar tissue on lower limb. Currently, there is still no consensus about the best surgical treatment for this deformity. The aim of this study is to report a case of a patient that was treated with a novel approach for the treatment of checkrein deformity of the hallux located in the forefoot, with satisfactory functional outcomes. Level of Evidence V; Therapeutics Studies; Expert Opinion.

Summary

Introduction

Checkrein deformity is an uncommon condition that it is clinically characterized by dynamic plantar flexion contracture of the interphalangeal joint (IPJ) and dynamic extension contracture of the metatarsophalangeal joint (MPJ) of the hallux[1]. Miranda et al Checkrein deformity treated through a forefoot approach: a case report mity such as distal tibia, ankle, talus and calcaneal fractures[1,2,3,4,5,6,7]. Checkrein deformity occurs due the entrapment or tethering of the flexor hallucis longus (FHL) in the callus formation at the fracture site or within scar tissue, proximal or distal to the flexor retinaculum[1]. Several surgical approaches have been described, there is no consensus which is the best option[1,8]. Most of the procedures are based on adhesion releases and FHL lengthening with approaches at the fracture site, retromaleolar site or midfoot[1,9]
