We describe 4 patients with an extension contracture of the little metacarpophalangeal joint without definite cause. We encountered this entity only in adolescent girls. When treated conservatively, we observed no improvements in motion. The main pathology of this entity was a hypertrophied dorsal capsule. The 2 patients treated by surgical release of the fifth dorsal capsule and collateral ligaments achieved considerable flexion 2 years later.
我们描述了4例无明确病因的小指掌指关节伸展挛缩患者。我们仅在青春期女孩中遇到这种情况。保守治疗时，我们观察到活动度没有改善。该病症的主要病理是背侧关节囊肥大。通过手术松解第五背侧关节囊和侧副韧带治疗的2例患者在2年后获得了显著的屈曲。
