Description

用于矫正槌状脚趾和爪状脚趾的球窝式植入件
交叉引用
本申请与2012年12月31日提交的标题为“用于矫正槌状脚趾和爪状趾的球窝式植入件”、申请序列号为61/747,429的临时申请是共同待决的,并要求该临时申请的优先权,整个申请的内容通过引用的方式并入于此。 
技术领域
本公开的装置和方法通常涉及槌状脚趾和爪状趾矫正植入件和装置。 
背景技术
槌状脚趾或收缩脚趾是第二、第三或者第四脚趾的近侧内趾骨关节的变形,致使其永久地弯曲并且给予其以槌状的外形。初始地,槌状脚趾是柔性的并且可以通过简单的措施矫正,但是如果不治疗,槌状脚趾需要被固定并需要外科手术干涉以用于矫正。具有槌状脚趾的人还可能在脚趾的中间关节的顶部上或者在脚趾的脚尖上具有鸡眼或老茧。他们还可能感觉他们的脚趾或足部疼痛并且难以找到舒适的鞋。爪状脚趾是第二、第三、第四或者第五脚趾的跖趾骨关节的变形,造成相应的脚趾中的近侧内趾骨关节和远侧内趾骨关节的非对抗性弯曲并且给予其以爪状的外形。 
可获得用于矫正槌状脚趾和爪状脚趾的多种治疗策略。槌状脚趾的第一治疗线(line of treatment)开始于具有柔软并且宽敞内包头(toe boxes)的新鞋。可以规定脚趾练习以伸展与加强相应的肌肉,例如,手动地轻轻伸展脚趾,利用脚趾从地板将东西拾起等。另一个治疗线包括利用带、衬垫或者非医疗鸡眼垫来缓解症状。进一步地,如果其它治疗选择失败,那么能够通过外科手术矫正槌状脚趾或爪状脚趾。外科手术可能涉及将螺钉、线等或者其它类似植入件插入到脚趾中以使它们变直。 
传统的外科手术方法通常包括使用克氏线(K-线)。但是近来,由于使用K-线的多个弊端,压紧螺钉被用作植入件。因为临时地插入K-线,所以它需要通过脚趾端部的坪突出(pings potruding)。由此,K-线经常导致针孔感染(pin tract infections)、固定失败等。K-线的其它弊端包括k-线的迁移与损坏,从而需要多次手术。 
因此,存在对于开发矫正脚趾骨变形的改进的脚趾骨植入件和方法的需要。
