It is important to evaluate each swan-neck deformity to determine the mobility and radiographic condition of the PIP joint. This information forms a basis for logical treatment. In those fingers with little or no loss of motion, the treatment alternatives include DIP joint fusions, dermadesis, or flexor tenodesis. With significant loss of PIP joint motion, an attempt is made to first restore passive motion by manipulation and lateral band or skin releases. It then becomes essential to restore flexor tendon excursion. In those patients with destroyed joint surfaces the salvage procedures of fusion and arthroplasty are the treatments of choice.
评估每一例天鹅颈畸形以确定近端指间关节（PIP）的活动度和影像学状况非常重要。这些信息构成了合理治疗的基础。对于那些活动度轻度丧失或无明显丧失的手指，治疗选择包括远端指间关节（DIP）融合术、皮肤固定术或屈肌腱固定术。当PIP关节活动度显著丧失时，首先尝试通过手法操作以及侧束或皮肤松解来恢复被动活动度。接着，恢复屈肌腱滑动就变得至关重要。对于那些关节面已破坏的患者，融合术和关节成形术等挽救性手术是首选治疗方法。
