we measured the bone mineral density (BMD) of the calcaneus of treated legs by single X-ray absorptiometry in 28 patients after treatment with non-weight bearing for more than 2 weeks. 6 out of the 28 patients had more than 30% lossof BMD compared with untreated side even after 6 months of treatment. 2 of the 6 experienced problems during treatment; one pseudoarthrosis of the tibia, and another communited fracture of the tarus treated with long term non-weight bearing. However, no severe bone loss of the calcaneus was found in the other 4 patients, and these were associated with non-localized pain of the foot. 4 patients with severe bone loss without treatment problems showed a tendency of the risk of osteoporosis (female, old age, post menopause) and low BMD compared with the same age group with leg treatment. The relation of bone loss of the foot and continuous pain of the foot after treatment is suspected. Further investigation is essential to determine the clinical significance of bone loss after treatment of fractures.
