Two patients with a deviated overlapping second toe due to rupture of the dorsal lateral metatarsophalangeal (MTP) collateral ligament and the lateral interosseous tendon were diagnosed, analyzed, and treated. Athletic activities were responsible for the tendon-ligament ruptures and the ensuing medial deviation of the second toe. Pain occurred in the second MTP joint, and a dorsal corn formed over the proximal interphalangeal joint (PIP). Reconstructive procedures included lengthening of the interosseous-lumbrical tendons and the collateral ligament on the medial side of the joint; a dorsal capsule incision; repair of the lateral collateral ligament and interosseous tendon; transfer of the flexor digitorum longus to the extensor digitorum longus; and shortening of the proximal phalanx in one patient. These soft tissue reconstructive procedures and realignment joint congruity are essential to relieve pain and prevent traumatic arthrosis. The treatment completed on the two patients resulted in relief of pain, satisfactory function, and alignment of the digits involved.
诊断、分析并治疗了两名因背外侧跖趾（MTP）侧副韧带和骨间侧肌腱断裂而导致第二趾重叠偏斜的患者。体育活动导致了肌腱韧带断裂以及随之而来的第二趾向内侧偏斜。第二跖趾关节出现疼痛，近端指间关节（PIP）背侧形成鸡眼。重建手术包括延长骨间蚓状肌腱和关节内侧的侧副韧带；背侧关节囊切开；修复外侧副韧带和骨间肌腱；将趾长屈肌转移至趾长伸肌；以及在一名患者中缩短近节趾骨。这些软组织重建手术和恢复关节一致性对于缓解疼痛和预防创伤性关节炎至关重要。对这两名患者完成的治疗缓解了疼痛，功能良好，受累趾对齐。
