背景情况:
- 初级增多性骨关节病 (PHO) 是一种罕见的遗传疾病,具有已确定的遗传亚型,但对临床亚型特征的理解有限.
- 以前的研究集中在病例报告和家庭分析上,在描述PHO的临床表现方面留下了一个空白.
研究的目的:
- 确定PHO的三个临床亚型的全球分布:完整的 (CO),不完整的 (IN) 和fruste (FR).
- 为了比较这些PHO亚型的临床特征.
- 为了确定临床和遗传亚型之间的潜在相关性.
主要方法:

01:26Bone Markings
5.0K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:31Osteoclasts in Bone Remodeling
2.8K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
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...
