Abductor pollicis longus suspensionplasty is a simple, effective treatment alternative forbasal joint arthritis. Use of a suspensionplasty technique acknowledges our current understanding of forces involved during pinch and grip, as well as the role of normal ligamentous anatomy. The primary rationale for performing suspensionplasty revolves around resisting the sagittal plane collapse that will occur when the thumb is loaded during pinch. In the absence of a volar-based suspension of the metacarpal, cantilever bending forces and axial force transmission will result in the dissipation of force along the thumb lever arm, and ultimately longitudinal collapse. Maximal grip and pinch strength require suspensionplasty, which can be performed using a variety of techniques. The author's current technique for suspensionplasty is described.
拇长展肌悬吊成形术是治疗第一腕掌关节关节炎的一种简单、有效的替代方法。采用悬吊成形术技术是基于我们目前对捏握过程中所涉及的力以及正常韧带解剖结构作用的理解。进行悬吊成形术的主要理由是抵抗在捏物时拇指受力时发生的矢状面塌陷。如果没有基于掌侧的掌骨悬吊，悬臂弯曲力和轴向力传递会导致沿拇指杠杆臂的力消散，并最终导致纵向塌陷。最大握力和捏力需要进行悬吊成形术，可采用多种技术来实施。本文描述了作者目前的悬吊成形术技术。
