Claw-toe deformity is a common and potentially debilitating condition that requires appropriate diagnosis and management. Operative treatments for claw-toe deformity depend on the severity and flexibility. In a subset of patients, causation for flexible clawed lesser toes can be related to the force transferred through the tendinous interconnection from the flexor hallucis longus tendon to the flexor digitorum longus tendon. The authors present a surgical technique for claw-toe deformity correction by releasing the tendinous interconnection from the flexor hallucis longus tendon to the flexor digitorum longus tendon in the midfoot area combined with toe manipulation. This technique can theoretically prevent the lack of toe grasp function associated with a flexor tenotomy as well as excessive stiffness associated with a flexor tendon transfer. Meticulous soft tissue dissection and protection of the medial plantar nerve are required to prevent complications.
爪形趾畸形是一种常见且可能使人衰弱的病症,需要进行适当的诊断和处理。爪形趾畸形的手术治疗取决于其严重程度和灵活性。在一部分患者中,柔软的爪形小趾的病因可能与通过腱性连接从拇长屈肌腱传递至趾长屈肌腱的力量有关。作者介绍了一种手术技术,即在中足区域松解从拇长屈肌腱到趾长屈肌腱的腱性连接并结合脚趾操作来矫正爪形趾畸形。从理论上讲,该技术可以防止与屈肌腱切断术相关的脚趾抓握功能丧失以及与屈肌腱转移相关的过度僵硬。需要细致的软组织解剖并保护足底内侧神经以防止并发症。
