Locking of the thumb metacarpophalangeal joint is a relatively rare condition. We report successful treatment in 11 cases of locking of the thumb. Ten patients were diagnosed at an average of 3.2 days (range: 0-21 days) from the injury onset, whereas one patient was diagnosed at 4 months from the injury. Seven of 11 cases underwent successful manual reduction, whereas the other four cases required surgical treatment. Among the surgically treated cases, all cases had a sharp prominent of the radial condyle of the metacarpal head. Therefore, this case series showed 1 chronic case and 4 of 10 cases with a nonround shape of metacarpal heads requiring open reduction.
拇指掌指关节绞锁是一种相对罕见的病症。我们报告了11例拇指绞锁的成功治疗病例。10例患者在受伤后平均3.2天（范围：0 - 21天）被诊断，而1例患者在受伤后4个月被诊断。11例中有7例成功手法复位，另外4例需要手术治疗。在接受手术治疗的病例中，所有病例的掌骨头桡侧髁均有尖锐突出。因此，该病例系列显示有1例慢性病例，10例中有4例掌骨头形状不规则需要切开复位。
