Skeletal dysplasias (SD) are a heterogeneous group of rare hereditary diseases with pronounced skeletal involvement and include over 750 phenotypes, which are associated with disease-triggering variants in more than 550 genes. In addition to orthopedic treatment, a network of various disciplines is necessary to ensure high-quality diagnostics and treatment for SD. This is ideally carried out at a center specialized in the treatment of rare bone diseases (European Reference Network on Rare Bone Diseases). The close networking of orthopedics with pediatrics and other disciplines is important to enable a state-of-the-art treatment and to monitor the influences of new forms of pharmacotherapy on the musculoskeletal apparatus.

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...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...
