のROM制限の合併を認めれば本疾患の合併の可能性を考える必要がある．, Dislocation of the metacarpophalangeal joint (MP joint) is a relatively rare trauma. We report a case of distal
radius fracture with dislocation of the index finger MP joint. Case: an 86-year-old man. The chief complaint: right
wrist joint pain. Current medical history: May 29, 2019 he fell and injured with right wrist joint. He complained of
a right wrist joint pain and visited a doctor on June 4. At the first visit, the diagnosis of distal radius fracture was
made by plain X-ray, and the cast was fixed. Therefore, the patient was referred to our clinic on June 6. Progression
2
of dislocation was observed at X-ray on June 20, but the possibility of ROM（ Range of motion）restriction was
communicated and consent was obtained for follow-up. Immediately after the cast was removed on July 11 and
ROM training was performed, a marked ROM restriction was observed in MP joint of the index finger. Therefore,
when X-ray was performed, dorsal dislocation of the index finger MP joint was observed. On the same day, he was
introduced to another hospital for the purpose of surgery. On July 30, surgery was performed. He was introduced to
our clinic for the purpose of rehabilitation. As of March 26, 2020, although ROM restrictions were recognized, no
ADL problems were observed. If ROM restriction of MP joints is observed during treatment for distal radius fracture,
it is necessary to consider the possibility of complication of dislocation of metacarpophalangeal joint.},
