Spontaneous flexor tendon rupture is a rare condition and the aetiology is not clear. We report 12 elderly Korean farmers with spontaneous flexor tendon ruptures. We found the rupture in the dominant hand in ten patients. A rupture in the little finger was found in all 12 patients (seven with both flexor tendons ruptured and five with only the profundus ruptured), in the ring finger in four patients (the profundus ruptured in all and both flexor tendons in two patients), and in the middle finger a partial rupture of the profundus in one patient. The tendons were ruptured close to the hook of the hamate. Repetitive friction between the flexor tendons and the hamate hook may cause the ruptures. The hamate hook was excised and the ruptured profundus tendons were reconstructed with tendon transfers with quite favourable functional recovery at follow-up of 1 to 2 years. The ruptured superficialis tendons were not reconstructed. Level of Evidence IV.
自发性屈指肌腱断裂是一种罕见病症，其病因尚不清楚。我们报告了12例患有自发性屈指肌腱断裂的韩国老年农民。我们发现10例患者的优势手出现断裂。12例患者均出现小指肌腱断裂（7例两根屈指肌腱均断裂，5例仅指深屈肌腱断裂），4例患者出现无名指肌腱断裂（4例均为指深屈肌腱断裂，2例两根屈指肌腱均断裂），1例患者中指指深屈肌腱部分断裂。肌腱在钩骨钩附近断裂。屈指肌腱与钩骨钩之间的反复摩擦可能导致断裂。切除钩骨钩，采用肌腱转位重建断裂的指深屈肌腱，在1至2年的随访中功能恢复良好。未重建断裂的指浅屈肌腱。证据等级为IV级。
