Swan neck deformity, or hyperextension of the proximal interphalangeal joint, may occur secondary to trauma, rheumatoid arthritis, cerebral palsy, or Ehlers-Danlos syndrome, and can be treated with tenodesis of one slip of the flexor digitorum sublimis tendon. This technique has several variations, differing primarily in the specific location and method that a single slip of the flexor digitorum sublimis tendon is secured, but they all serve to create a static volar restraint against hyperextension. Options include tunneling the tendon through the bone of the proximal phalanx, attaching the tendon to the A1 or A2 pulley, or securing the tendon with bone anchors in the proximal phalanx.
鹅颈畸形，即近端指间关节过伸，可能继发于创伤、类风湿性关节炎、脑瘫或埃勒斯-当洛综合征，可通过对指浅屈肌腱的一条束带进行腱固定术来治疗。该技术有多种变体，主要区别在于固定指浅屈肌腱单束带的具体位置和方法，但它们都用于产生对抗过伸的静态掌侧约束。选择包括将肌腱穿过近节指骨的骨隧道、将肌腱附着于A1或A2滑车，或用骨锚将肌腱固定在近节指骨上。
