title: Parathyroid hormone: is there a role in fracture healing?
abstract: Parathyroid hormone is a well-known regulator of calcium metabolism in the body. It binds to osteoblasts and assists in the regulation of bone turnover. Changes in parathyroid hormone levels have been documented in pathologic states such as osteoporosis, and fluxes are also noted during healing of fractures. Because fracture healing requires time and is sometimes unreliable, a search for fracture-healing adjuvants that accelerate the healing rate and improve reliability of healing is compelling. Parathyroid hormone, as a systemic mediator of calcium and bone metabolism, is a good candidate. Much research has been accomplished in animal models examining the role of parathyroid hormone in fracture healing. Although further research is required, especially in human fracture patients, early indicators are that parathyroid hormone may play a role in accelerating fracture healing in healthy patients and in reducing rates of fracture nonunion in compromised patients or tissue beds.
