interosseous border
bone anatomy
Quick Summary
The interosseous border is a ridge on the shaft of bones that serves as an attachment point for the interosseous membrane. This membrane is a strong sheet of fibrous tissue that connects the shafts of two parallel bones. In the forearm, it connects the radius and the ulna. Similarly, another interosseous membrane connects the shafts of the tibia and fibula in the lower leg. These membranes help stabilize the bones and provide surface area for muscle attachments.123
