面对全髋关节置换多种手术方式,为什么要选择DAA呢?今天小编将通过临床效果及假体选择向各位介绍DAA的应用。
骨科手术的一个基本原则,是倾向于通过肌肉间隙和神经间隙的空间进行手术,将软组织损伤最小化。虽然所有全髋关节置换手术方式都取得优良结果,但DAA是唯一一种利用肌肉间隙和神经间隙进行的手术方式。
研究显示,DAA手术方式比后外侧入路、前外侧入路更好地保护了外展肌群、外旋肌群[1-3]。

在术后恢复方面,DAA THA可能比较有优势[4],多项研究[5-8]显示DAA存在更少的疼痛,更早地恢复髋关节功能,更快地恢复正常步态,更短的住院时间,术后早期及晚期Harris评分更高,更好的活动范围等优势。
短柄假体可以解决DAA手术方法中股骨暴露与假体植入的难题。短锥型柄属于干骺端稳定型假体,冠状面呈楔形,与股骨干大转子结合后获得良好的稳定性,同时还能在植入时灵活调整角度。为DAA手术方法提供了一个很好的假体选择。
嘉思特MINI微创生物股骨柄干骺端+近端骨干双重锁定机制、双锥度设计实现可靠的初始稳定,近端Ti+HA双涂层设计,利于远期骨长入。
工欲善其事必先利其器,DAA THA手术医生必须有该手术的基础工具才能开展手术,例如:弯的牵开器、带偏心距的拉钩等。嘉思特提供专业的DAA手术工具,为医生开展一台完美的DAA THA手术奠定基础。
