Abstract

We report a case of 4th metacarpal head collapse of a 19-year-old healthy man. MRI revealed Tl low and T2 high regions in the collapsed 4th metacarpal head, as well as in the right 3rd and left 4th metacarpal head. Our initial diagnosis was occult compression fracture due to avascular necrosis, known as Dieterichs disease. However, pathological findings of surgically resected right 4th metacarpal head were compatible with transient osteoporosis and metacarpal head fracture followed by active tissue repair. The autologous osteochondral transplants from costchondral junction survived and maintained their size and shape even at 10-year follow-up.
