Abstract

Locking of the metacarpophalangeal joints has been occasionally reported in older adults, but reports of this problem are rare in younger individuals. We report 8 young adult patients with a metacarpophalangeal joint locked in 90° flexion after minor trauma. The cases included 6 little fingers and 2 thumbs in 1 male and 7 female patients aged 16 to 39 years. All were easily reduced closed. We postulate the mechanism of injury.

摘要

掌指关节绞锁在老年人中偶有报道，但在年轻人中这种问题的报告很少。我们报告了8例年轻成人患者，他们在轻微创伤后掌指关节锁定在90°屈曲位。这些病例包括6例小指和2例拇指，患者为1名男性和7名女性，年龄在16至39岁之间。所有病例均经手法闭合复位成功。我们推测了损伤机制。
