The location of 327 solitary enchondromata of the hand reported in the English and German medical literature and 30 solitary enchondromata treated at our hospital was studied. Four were located in the carpus, 70 in the metacarpals and 283 in the phalanges. There were highly significant preferences for involvement of the proximal phalanges and the little finger ray. The proximal phalanx of the little finger was the most commonly involved bone.
