The intertarsal joint is a synovial roll-and-glide joint. Ligament damage and luxations of this joint are often the result of traumatic injury or growth deformities and result in significant functional impairment. A 9-month-old female Pekin duck ( Anas platyrhynchos domesticus) was examined because of progressive, nonweight-bearing lameness of the left leg. Moderate effusive swelling was present at the level of the left intertarsal joint, without radiographic evidence of bone involvement. The duck failed to respond to nonsteroidal anti-inflammatory medications and analgesia and was diagnosed with rupture of the medial collateral ligament. Extracapsular surgical correction using bone tunnels and circumferential nylon suture on the medial aspect of the intertarsal joint led to a complete clinical resolution with normal return to function 2 weeks after surgery. This report reviews the anatomy and function of the intertarsal joint in the duck and details a simple extracapsular repair technique useful in the correction of collateral ligament rupture in this joint of ducks.
跗间关节是一种滑膜滚动-滑动关节。该关节的韧带损伤和脱位通常是创伤性损伤或生长畸形的结果，并导致严重的功能障碍。一只9个月大的雌性北京鸭（绿头鸭家鸭）因左腿进行性非负重跛行而接受检查。左跗间关节水平出现中度渗出性肿胀，影像学检查未发现骨骼受累迹象。这只鸭子对非甾体类抗炎药和镇痛治疗无反应，被诊断为内侧副韧带断裂。在跗间关节内侧使用骨隧道和环形尼龙缝线进行关节囊外手术矫正，术后2周临床症状完全消失，功能恢复正常。本报告回顾了鸭跗间关节的解剖结构和功能，并详细介绍了一种简单的关节囊外修复技术，该技术可有效矫正鸭该关节的副韧带断裂。
