Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years and older (Adult, Older Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

Eligible patients must meet all of the following inclusion criteria:

1. patients with an acute open fracture of the tibial shaft secondary to trauma assessed by medical examination and current radiographs indicated for open fracture reduction and internal fixation using osteosynthesis plates or intra-medullary nails
2. soft tissue management (if medically warranted, eg. debridement, irrigation, application of antibiotics) performed according to local hospital practice no later than 24h after the trauma
3. male and female patients >= 18 years
4. body mass index (BMI) 16-33 (minimum body weight 50 kg, maximum 140 kg)
5. females of child-bearing potential must be willing to undergo a pregnancy test (urine) prior to treatment start (at screening)

6. females of child-bearing potential randomized in the intervention group must agree to have acceptable contraception for at least 3 months after receiving the study medication.

   Acceptable contraceptive measures are:

   • Hormonal types of birth control with a failure rate of less than 1% per year (such as implants, injections, combined oral contraceptives, patches or other methods) or copper IUDs or other IUDs with a failure rate of less than 1% per year, AND
   • An additional barrier type of birth control measure (such as condoms, diaphragms, cervical caps, etc.) Sterilized women and abstinent women of child-bearing potential will not be required to take contraceptive measures
7. willingness and ability to understand, participate and comply with the study requirements
8. patient be able to give consent personally and sign the Informed Consent Form.

Exclusion criteria:

Patients will be not eligible if they meet one of the following exclusion criteria:

1. IIIc open fracture according to the Gustilo-Anderson classification
2. tibial defects requiring bone-grafting (e.g. large segmental defects)
3. duration from trauma to surgery longer than 14 days
4. concomitant acute bone injuries and/or major skin or other significant injuries that in the opinion of the investigator would interfere with the tibial shaft fracture healing process
5. concomitant ipsilateral tibial fractures other than in the diaphyseal region
6. evidence of immune suppression
7. suspected or known hypersensitivity to the study medication or components of it
8. evidence of hypercalcemia
9. hyperparathyroidism
10. on treatment and/or planned treatment with products containing PTH (e.g. Forteo)
11. pregnant or lactating females
12. participation in another clinical trial within the last 3 months
13. active or past history of malignant tumor
14. history or evidence for any hereditary or acquired chronic metabolic bone disease other than primary osteoporosis.
15. history or evidence for any clinically relevant organ failure or any other relevant medical condition that, in the opinion of the investigator, will relevantly interfere with the assessment of study outcome or will impose hazard to the patient if study therapy will be initiated
16. known history of allergy to anaesthetics
17. evidence of moderate or severe renal failure (serum creatinine > 3.0 times ULN, NCI CTC grades 3 and 4)
18. known history of allergic thrombocytopenia (type II) induced by heparin
19. inexplicable elevations of alkaline phosphatase or alkaline phosphatase > 5.0 times ULN, NCI CTC grades 3 and 4
20. prior external beam or implant radiation therapy to the skeleton
