A girl with a deviated index finger

A 7-year-old girl was seen at the ER with severe pain of her index finger after twisting her hand whilst performing a handstand. Physical examination and X-rays showed an isolated dorsal dislocation of the metacarpophalangeal joint, also known as a Kaplan’s lesion. A Kaplan’s lesion is a complex dislocation with volar plate interposition. Therefore, most of the lesions require surgical reduction, preferably from a dorsal approach.
