Individuals with spinal cord injury sustain significant loss of bone mass in their lower extremities (20-40% or more). This study evaluates the ability of PTH and weight-bearing, two interventions that build bone, to increase bone mass in this population.

Primary Outcome Measures:
  • BMD at Left Total Hip [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]
    Bone mineral density (gm/cm2) of the total hip region of interest on the left

Secondary Outcome Measures:
  • P1NP [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]
    amino-terminal propeptide of type I collagen (P1NP)

Enrollment: 12

Arms Assigned Interventions
Experimental: PTH/Weight-Bearing Drug: teriparatide
teriparatide 20ug daily sc for 6 months
Other Name: Forteo
Other: weight-bearing
device assisted walking
Other Name: exercise

Detailed Description:
This pilot project aims to evaluate PTH with weight-bearing in a group of individuals with chronic SCI and loss of bone mass in their lower extremities. A convenience sample of 12 people with SCI will be enrolled into a 6 month study assessing the effects of a weight-bearing regime plus daily PTH (Forteo 20ug sc) on BMD and bone markers. Subjects will be evaluated at 3 and 6 months after initiating treatment with measurement of bone density as well as bone markers of formation and resorption. An optional extension to 12 months will be offered to all subjects.

Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Age 18-75 years
  2. Complete SCI - total loss of motor function below level of lesion
  3. Capable of positioning to have DEXA performed
  4. Capable of undertaking the weight-bearing exercise regime
  5. Capable of reading and understanding informed consent document
  6. Able to self-administer PTH or have someone in the family who can do so
  7. T score <-2.5 or Z score <-1.5 on evaluation of total hip BMD
  8. No known endocrinopathies
  9. Normal TSH levels
  10. Normal 25-OH vitamin D levels
  11. Normal calcium levels
  12. Normal renal function (creatinine <2.0mg/dl)
  13. Able to return for all follow-up visits

Exclusion Criteria:

  1. Surgical or other intervention resulting in metal or anatomy precluding obtaining DEXA and/or MRI measurements
  2. Other medical conditions that in the opinion of the investigator would preclude the subject from completing the study
  3. History of malignancy
  4. History of radiation therapy
  5. Unable to self-administer PTH or have it administered
  6. Elevated liver function tests >2x normal
  7. For males, significantly abnormal free testosterone levels
  8. Currently being prescribed anti-convulsants
  9. Currently being prescribed glucocorticoids, other than inhaled glucocorticoids
  10. Currently being prescribed any bone-active agents, including any bisphosphonate, raloxifene, hormone therapy (estrogen and estrogen/progestin), calcitonin or strontium-containing compounds.
  11. No previous history of bisphosphonate use
  12. No previous use of other bone-specific agents during past 2 years
