Entrapment of the sesamoids within the metacarpophalangeal joint can result in irreducible dislocations; however, dysfunction from trauma-induced, chronic sesamoiditis is unfamiliar. Twenty-five patients with intractable posttraumatic pain of the metacarpophalangeal joint of the thumb are reported. The mechanisms of the palmar plate injury included hyperextension, direct compression, shear forces, and lateral stress. Sesamoidectomy achieved good results in 80% of patients as evidenced by return to preinjury activities. Residual joint stiffness was present in 20% of patients, and 8% had significant residual pain. Traumatic microtears appear to produce pathologic findings in the perisesamoid tendon and/or sesamoid-metacarpal articulation.
籽骨被困于掌指关节内可导致不可复位的脱位；然而，创伤性慢性籽骨炎所致功能障碍并不常见。本文报告了25例拇指掌指关节创伤后顽固性疼痛患者。掌板损伤机制包括过伸、直接压迫、剪切力和侧方应力。籽骨切除术使80%的患者取得了良好效果，表现为恢复到伤前活动水平。20%的患者存在残留关节僵硬，8%有明显残留疼痛。创伤性微撕裂似乎在籽骨周围肌腱和/或籽骨-掌骨关节处产生病理改变。
