Traumatic trapeziometacarpal joint dislocation of the thumb accounts for less than 1% of all hand injuries. This injury is even less common in children. Optimal treatment strategies for this injury are still the subject of debate for both children and adults. We report a case of recurrent posttraumatic trapeziometacarpal joint dislocation in an eight-year-old girl. We believe our case is the first report of recurrent acute dislocation leading to chronic dislocation in the English medical literature. Restoring the anatomy and biomechanics of the trapeziometacarpal joint is essential when treating these injuries; for this reason, surgical treatment is usually indicated. Overall, the prognosis of trapeziometacarpal dislocation treated acutely is favorable and stable over time. However, the role of open surgery and ligament reconstruction remains controversial, especially in children.
拇指创伤性大多角骨-第一掌骨关节脱位占所有手部损伤的比例不到1%。这种损伤在儿童中更为罕见。对于儿童和成人，这种损伤的最佳治疗策略仍是一个有争议的话题。我们报告了一例8岁女孩复发性创伤性大多角骨-第一掌骨关节脱位的病例。我们认为我们的病例是英文医学文献中首例复发性急性脱位导致慢性脱位的报道。治疗这些损伤时，恢复大多角骨-第一掌骨关节的解剖结构和生物力学至关重要；因此，通常需要进行手术治疗。总体而言，急性治疗的大多角骨-第一掌骨脱位预后良好且随时间推移稳定。然而，开放手术和韧带重建的作用仍存在争议，尤其是在儿童中。
