Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

RATIONALE: Collecting and storing bone samples from patients with osteoporotic and nonosteoporotic fracture to study a special vessel subtype in the laboratory may help surgeon learn more about the relationship between bone mineral density (BMD) and a special vessel subtype (type H vessel).

PURPOSE: This research study is looking at changes of a special vessel subtype in bone samples from patients with osteoporotic and nonosteoporotic fracture.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OBJECTIVES:

1. Establish type H vessel in bone specimen in patients with hip fracture.
2. Explore the correlation of BMD and type H vessel.

OUTLINE:

1. Collect human bone specimens from patients with Osteoporotic and Nonosteoporotic Fracture.
2. Provide a repository for storage of tissue and make these specimens available for approved projects by laboratory-based investigators.
3. Observe the type H vessel in bone slice by immunofluorescence staining.
4. Collect clinical data on these patients including bone mineral density.
5. Investigate the relationship between BMD and type H vessel.
