Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Bone Markings01:26

Bone Markings

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...
Growth of Cartilage and Bone Tissue01:27

Growth of Cartilage and Bone Tissue

Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...
Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

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 bone...
Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
Introduction to Joints00:58

Introduction to Joints

The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no movement.

Summary
This summary is machine-generated.

Acromegaly, caused by excess growth hormone (GH) and insulin-like growth factor-I (IGF-1), significantly impacts bone metabolism and joints. Understanding these osteoarticular effects is crucial for managing patient complications and immobility.

Area of Science:

  • Endocrinology
  • Bone Metabolism
  • Rheumatology

Background:

  • Acromegaly results from excess growth hormone (GH) and insulin-like growth factor-I (IGF-1), typically due to pituitary tumors.
  • The precise impact of GH excess on bone metabolism and the development of osteoarticular complications remain areas of active investigation.
  • Acromegaly is traditionally linked to secondary osteoporosis, but the role of bone mineral density (BMD) in fracture risk is debated, highlighting the importance of bone quality.

Purpose of the Study:

  • To elucidate the complex effects of growth hormone (GH) and insulin-like growth factor-I (IGF-1) excess on bone metabolism.
  • To investigate the prevalence and significance of osteoarticular manifestations in acromegaly patients.
  • To assess the current understanding of fracture risk in acromegaly, considering both BMD and bone quality.

Main Methods:

  • Review of existing literature on acromegaly, GH/IGF-1, bone metabolism, and osteoarticular complications.
  • Analysis of studies examining bone turnover markers and bone quality assessments in acromegaly.
  • Evaluation of clinical data regarding the incidence and impact of articular manifestations.

Main Results:

  • Growth hormone (GH) excess increases bone turnover, with associated changes in bone markers.
  • Articular manifestations are common, often presenting early, and contribute significantly to morbidity and immobility.
  • The role of BMD in predicting fractures in acromegaly is uncertain, suggesting bone quality is a more critical factor.

Conclusions:

  • Acromegaly profoundly affects bone and joint health, leading to significant clinical complications.
  • Early recognition and targeted therapy for osteoarticular changes in acromegaly are essential for reducing morbidity.
  • Further research into bone quality is needed for accurate fracture risk assessment in acromegaly patients.
