[Breast hypertrophy and dorsolumbar spine. Prognostic influences of lumbar lordosis: preliminary results].

In a prospective study, the influence of a mammary hypertrophy on some clinical and radiological parameters of the lumbar and dorsal spine had been studied in 14 women comparatively to 14 control women, before and after a reduction surgery. Clinically, the frequency of the lumbar pain was identical in the two groups of patients before surgical treatment but a significant decrease of the frequency and the intensity of the lumbar pain was found after the surgery in the mammary hypertrophic group (p less than 0.01). Some radiological parameters of lordosis and the dorsal kyphosis were significantly higher in mammary hypertrophic patients than in control patients. After surgery, an increase of parameters of lordosis was observed associated with a significant decrease of the dorsal kyphosis (p less than 0.05). Nevertheless, by use of a radiological classification of the lumbar lordosis with the Ferguson's indice, two main groups of lordosis had been distinguished. The intensity of the lumbar pain and the dorsal kyphosis were significantly higher in patients with a low indice than in those with an high indice. More, the dorsal kyphosis has decreased only in patients with a low anterior lumbar indice. In conclusion, a mammary hypertrophy must be searched in women with a lumbar pain and an surgical treatment may be proposed.
