Fracture-Specific Inclusion Criteria
1. Radiograph-confirmed diagnosis of acute, single isolated fracture of the humerus. AO classification 11A2, 11A3 and 11B1, 11B2 and 12A1, 12A2, 12A3 and 12B1, 12B2 (The Netherlands); AO Classification 11A1, 11A2, 11A3 and 11B1, 11B2 and 12A1, 12A2, 12A3 and 12B1, 12B2 and 13A1, 13A2 and 13B1, 13B2 (Germany).
2. Fracture is closed, Gustilo Type I or II.
General Inclusion Criteria
3. Skeletally mature men and women, 50 years of age or older (The Netherlands only) or 61 years of age or older (Germany only) at time of index injury.
4. a) Female patients of child bearing potential agree to use double barrier method of contraception (The Netherlands only) b) Female patients of non-child bearing potential must meet one of the following criteria (The Netherlands only):
* Postmenopausal for at least 1 year, or
* Documented oophorectomy or hysterectomy, or
* Surgically sterile

Fracture-Specific Exclusion Criteria
1. Index treatment is greater than 28 days (The Netherlands only) or 14 days (Germany only) post fracture
2. Open fractures with severe contamination.
3. Extremely comminuted fractures where insufficient holding power of the balloon on the intramedullary canal is probable.
4. Marked bone loss or bone resorption patients, who due to a prior delayed union or non-union of the bones or other illnesses, may not be able to have their fracture adequately reduced prior to placement of the IlluminOss-device. This could leave bone void spaces that would preclude the device from maintaining alignment of the fractured bone.
5. Previous fracture of affected limb.
General Exclusion Criteria
6. Pregnant or lactating (The Netherlands only).
7. Patients with a contralateral fracture of the forearm or humerus (Germany only).
8. Active or incompletely treated infections that could involve the site where the device will be implanted.
9. Distant foci of infections that may spread to the implant site
10. Uncooperative patients or patients, who are incapable of following directions (for example as a consequence of a neurological or psychiatric disorder).
11. Concomitant metabolic disorders that may impair bone formation.
12. Osteomalacia.
13. Allergic to implant materials or dental glue.
14. Vascular insufficiency, muscular atrophy, or neuro-muscular disease.
15. Polytrauma patients (multiple injuries resulting from a high-impact event, eg- a motor vehicle accident).
