The role of teriparatide in diabetes patients with CN has not been studied, till date. Keeping the pathophysiology of CN in mind, the present study plans to assess the efficacy of teriparatide in chronic CN by studying the change in bone remodeling as quantitated by F18 SPECT CT, BMD and markers of bone turnover. We will also assess the benefits of teriparatide, if any, on the foot morbidity i.e incidence of fractures, progression of deformity or need for amputation over the follow up period of 18 months.
