[An investigation on X-ray features of phalanges unguinal tuberosity for 2292 cases of normal adults].
The phalanges unguinal tuberosity of normal adults are always in different shapes because of many normal variations in anatomy. According to the difference in shape, the authors divided them into three types: smooth type (62.65%), mushroom type (28.40%) and irregular type (8.49%). It seems that the difference in shape forms are related with the person's age. It is of practical importance to distinguish occupational from non-occupational osteolytic lesions of finger's distal end if one bears in mind these normal physiological variations in anatomy.
