We report a patient with limitation in active extension of the metacarpophalangeal joint (MCPJ) of the ring finger due to a scarred JT in a 37-year-old man. Surgical exploration showed a hard, fixed and scarred JT in the third intermetacarpal space. After resection of the scarred JT, the patient achieved full range of active extension of the ring finger MCPJ. Scarring of the JT may decrease excursion of the extensor digitorum communis and must be considered as one of the differentials in patients with limitation in MCPJ extension. Level of Evidence: Level V (Therapeutic). 抄録：英語フィールド
