[An analysis of a case series of 342 short-stature patients examined by the Tanner-Whitehouse 2 (TW2) method].
342 short-stature patients were examined to assess the agreement between anagraphic and bone ages. 190 men and 152 women (age range: 0 to 17.5 years) underwent conventional radiographs of the left wrist. The radiographs were studied with the TW2 method which provides an index of the skeletal maturity of short and long bones and a global index of the hand. The bone ages thus obtained were compared with anagraphic ages. Patients' statures were compared with their parents' ones. Finally, radiation exposures were evaluated. Anagraphic and bone ages were in agreement in 199 patients and in disagreement in 220. Three patients were adult. The short stature in 78 patients was in agreement with their parents' one, while 253 patients had at least one parent with normal stature. No comparison could be made in 11 patients. In conclusion, TW2 is a simple method to calculate bone age (in months and years) and to select the patients to submit to further examinations and to hormone therapy.
