Abstract：
Checkrein deformity is characterized by the dynamic status of the hallux, in which flexion deformity is aggravated by ankle dorsiflexion and relieved by ankle plantarflexion. In most cases, a checkrein deformity occurs secondary to trauma or following surgery. It has been suggested that the flexor hallucis longus tendon tethers or entraps scar tissue or fracture sites. Improvement with conservative treatment is difficult once the deformity has already become entrenched, and surgical management is usually required in severe cases. Various surgical options are available for the correction of checkrein deformities. It includes a simple release of adhesion at the fracture site; lengthening of the flexor hallucis longus by Z-plasty at the fracture site combined with the release of adhesion; lengthening of the flexor hallucis longus by Z-plasty at the midfoot, retromalleolar, or tarsal tunnel area; and flexor hallucis longus tenotomy with interphalangeal arthrodesis for recurrent cases. This review aimed to summarize the overall etiology, relevant anatomy, diagnosis, and treatment of checkrein deformities described in the literature.
摘要：
Checkrein畸形的特征在于hallux的动态状态，其中屈曲畸形因踝背屈而加重，因踝趾屈而减轻。在大多数情况下,checkrein畸形继发于外伤或手术后。有人认为，长屈肌腱系链或包裹疤痕组织或骨折部位。一旦畸形已经根深蒂固，保守治疗很难改善，严重病例通常需要手术治疗。各种手术选择可用于纠正checkrein畸形。它包括在骨折部位简单地释放粘连；在骨折部位通过Z-成形术延长长屈肌，同时释放粘连；在中足通过Z-成形术延长长屈肌，后踝关节,或tar骨隧道区域；和指间关节固定术的长指屈肌切开术治疗复发性病例。这篇综述旨在总结总体病因，相关解剖学,诊断,以及文献中描述的checkrein畸形的治疗。
