Abstract:
A 64-year-old woman came to our hospital because of intermittent claudication of her left leg. She had undergone meniscectomy of the left knee in her 30s. The ankle-brachial pressure index of the left leg was 0.70. Imaging examinations showed occlusion of the popliteal artery compressed by an enlarged sesamoid bone with osteophytes. No anatomic abnormalities of vessels and muscles were seen. A particular type of popliteal entrapment syndrome was diagnosed. After resection of the sesamoid bone, thromboendarterectomy and patch plasty were performed. After the operation, the claudication was improved, and the ankle-brachial pressure index of the left leg increased to 0.91.

Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
