Tillaux-Chaput tubercle fractures occur in adolescents, which are often associated with the separation of the distal tibial growth plate. These types of fractures are rare in adults and even rarer when accompanied by a rupture of the peroneus tertius muscle. Given the limited number of reported cases, there is limited clinical awareness, resulting in missed diagnoses and delayed treatment, ultimately affecting ankle function.
We report a case of an adult patient who experienced a right ankle injury resulting in swelling and pain after a traffic accident. Initial examination failed to identify the rupture of the peroneus tertius muscle, but the patient was observed to have restricted dorsiflexion and eversion of the foot. Surgical exploration through an anterolateral incision confirmed the rupture and the muscle was then repaired. The patient received four weeks of cast immobilization and then engaged in progressive rehabilitation exercises.
This report shares the diagnostic and therapeutic experiences of an adult with a Tillaux-Chaput tubercle fracture associated with peroneus tertius muscle rupture to improve clinical recognition of such injuries, thus preventing misdiagnosis and treatment delays.
Tillaux-Chaput 结节骨折发生于青少年，通常与胫骨远端生长板分离有关。这些类型的骨折在成年人中很少见，而当伴有第三腓骨肌断裂时则更为罕见。由于报告的病例数量有限，临床认识有限，导致漏诊和治疗延误，最终影响踝关节功能。
我们报告了一例成年患者，因交通事故导致右踝关节受伤，出现肿胀和疼痛。初次检查未能发现第三腓骨肌断裂，但观察到患者足背屈和外翻受限。通过前外侧切口进行手术探查证实了断裂，并对肌肉进行了修复。患者接受了四周的石膏固定，然后进行了渐进性康复锻炼。
本报告分享了一例成人 Tillaux-Chaput 结节骨折合并第三腓骨肌断裂的诊断和治疗经验，以提高对这类损伤的临床认识，从而避免误诊和治疗延误。
