The incidence rate of pelvic fractures increases dramatically with age, from 5.4 and 3.8 per 10,000 person-years in women and men aged 65 to 69 years to 93.5 and 44.5 per 10,000 person-years in women and men aged 90 years and older, respectively. Pelvic fractures are accompanied by severe pain, chronic immobility and loss of function and independence in the elderly. Pelvic fractures consume substantial healthcare resources, and based on administrative claims data, they are one of the most costly osteoporosis related fractures. Un-healed fractures, occurring in one-third of pelvic fracture patients at 3 months, can cause continued pain and impact mobility. With aging of the population and expected concomitant increase in the incidence of pelvic fractures, there is a pressing need to find effective treatments that will accelerate healing. Fracture of the pubic ramus is most relevant and practical for randomized double-blinded placebo-controlled study as this fracture is accompanied by severe pain and immobility in elderly, is associated with delayed fracture healing, and is almost always treated non-operatively. The current standard of care for pelvic fractures includes pain management, patient mobilization, and the prevention of complications associated with comorbid conditions. The investigators hypothesize that development of a successful adjunctive therapy to accelerate fracture healing would lead to improved care and reduce both direct and indirect costs from pelvic fractures.
Postmenopausal women and men >65 years of age with acute pelvic fractures, occurring with minimal trauma, presenting to Helen Hayes Hospital, Hospital for Special Surgery, or New York Hospital (Cornell Medical). Patients that have either one or multiple pelvic fractures or sacral and pelvic fractures will be included in the study. Subjects must start treatment within one month of hip fracture.
- Persons unable to complete the NRS and other surveys based on their mini-mental status score (≤18; consistent with moderate and severe cognitive impairment)
- Previously (prior to fracture) non-ambulatory subjects
- Exclusion criteria related to contraindication or intolerance to TPTD:
- Hypersensitivity to TPTD
- Patients with increased risk of osteosarcoma: Paget's disease, history of radiation exposure
- Patients with active hypercalcemia
- Current hyperparathyroidism and other metabolic bone disease including osteogenesis imperfecta
- History of multiple renal calculi or renal calculus within the last 2 years
- Normal alkaline phosphatase levels will not be used as an entrance criterion because most fracture patients will have elevations due to the acute fracture. However, the investigators will attempt to obtain lab tests from the period prior to fracture to determine if they were normal. If unexplained elevations in alkaline phosphatase are found in labs prior to the fracture, we will exclude that subject.
- Evidence of metastatic cancer or history of bone cancer or any active cancer other than basal or squamous cell carcinoma.
