Institutional Review Board, Hospital for Special Surgery
The safety of our participants is our top priority. The trial/study is approved and periodically reviewed by the Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.
Before enrolling in a clinical trial or research study, the investigator will explain the purpose of the trial/study, its expected benefits, any possible risks or side effects, and what your role will be. If you want to join the trial/study, you must sign informed consent documents. You can leave a trial/study at any time without penalty.
For further information, see Understanding Clinical Trials/Research Studies.

Teriparatide (Forteo) is a potent osteoporosis medication that helps prevent fractures. However, we know little about its effect on the hip. The purpose of this study is to determine what changes Teriparatide has on hip structure and how it might help reduce hip fracture risk. We will evaluate hip bone samples from patients that we will be treating with either teriparatide (Forteo) or a placebo (an inactive substance) for 6 weeks before their surgical hip replacement. The overall participation in this study will be over a period of 10 weeks. A total of 60 subjects (men and women) will participate in this study at HSS and HHH. Study participation will involve a total of 3 study visits. Most visits are expected to last 30-60 minutes, except the last visit, which is the date of surgical hip replacement.
Inclusion Criteria
• Age 60-85
• Male or postmenopausal (women who have had no menses for one year) female BMD T-Score at the Spine (at least 2 evaluable vertebrae), Total Hip, Femoral Neck or Trochanter between ¬

• Degenerative joint disease of the hip (osteoarthritis) requiring total hip arthroplasty, based on
radiologic and clinical impression by Dr Bostrom.
Exclusion Criteria
• Any contraindications to use of TPTD
• Age younger than 60, greater than 85.

• Prior radiation treatment
• Secondary hyperparathyroidism due to vitamin 0 deficiency or renal disease
• Active hyperthyroidism or excessive thyroid hormone replacement (with TSH below normal range)
• Moderately severe renal impairment (serum creatinine>2.0 mg/L or estimated GFR <30 ml/min)
• Severe vitamin D deficiency (250HD level <10 ng/ml)
• History of multiple renal calculi or renal calculus within 2 years
