THORACIC KYPHOSIS SEVERITY INCREASES RISK OF VERTEBRAL FRACTURE. THORACIC KYPHOSIS INCREASES OVER A 3 YEAR PERIOD. 

comment from James M. Cox DC DACBR: If for no other condition than hyperkyphosis of the thoracic spine, f/d decompression is worth having in the doctor’s treatment bag. Posture control coupled with f/d is an excellent addition to thoracic kyphosis care when you consider the possible complications as described in the report by Roux et al.

(from Roux, C; Fechtenbaurn, J; Kolta, S; Said-Nahal, R; Briot, K; Benhamou, CL.  Prospective Assessment of Thoracic Kyphosis in Postmenopausal Women With Osteoporosis. JOURNAL OF BONE AND MINERAL RESEARCH 25 (2). FEB 2010.  p.362-368)

 The relation of thoracic kyphosis, its influence on incident fractures and quality of life over three years in postmenopausal women with osteoporosis and the effect of strontium ranelate on thoracic kyphosis progression was studied on women with postmenopausal osteoporosis.  Vertebral fractures were assessed on lateral thoracic radiographs performed at baseline and at three years according to standardized procedure. Kyphosis index (KI, %) was defined as the percentage ratio between the maximum depth of thoracic curvature and the height measured from the T4 to the T12 vertebrae. Baseline characteristics of the 3218 patients (1594 strontium ranelate, 1624 placebo) were mean age 73.3 years, spine bone mineral density (BMD) T-score (1-2-4)-3.1, femoral neck T-score -3.0, and KI 25.4%.   In the placebo group, patients with the highest baseline KI experienced significantly more vertebral fractures than those with medium KIs or the lowest KIs. There was no difference in the risk of nonvertebral fractures according to baseline KI. Three-year changes in quality-of-life physical scores reflected significantly better status for patients in the lowest tertile of KI compared with those in the highest at baseline. Over three years, the kyphosis index increased for all patients, indicating worsening of thoracic kyphosis, whatever the presence of prevalent or incident vertebral fractures. This KI progression was lower in the strontium ranelate group than in the placebo group. Thoracic kyphosis is a risk factor for vertebral fractures over three years and influences physical capacity changes in postmenopausal women with osteoporosis. Thoracic kyphosis progression over three years is lower in a subgroup of strontium ranelate-treated patients compared with placebo-treated patients.
