Musculoskeletal disorders 

Tendinopathies are a group of clinical disorders characterized by chronic, localized tendon pain and impaired function that worsen with mechanical loading. They result primarily from repetitive tendon overuse, failed tendon healing, and degenerative changes rather than acute inflammation alone. Tendinopathies may present as acute or chronic conditions and commonly affect the rotator cuff, Achilles tendon, patellar tendon, lateral epicondyle (tennis elbow), medial epicondyle (golfer's elbow), and wrist tendons.

Heterotopic ossification (HO) is the abnormal formation of mature lamellar bone within soft tissues where bone does not normally exist. It most commonly develops after musculoskeletal trauma, fractures, burns, spinal cord injury, traumatic brain injury, or orthopaedic surgical procedures, particularly around major joints.

Juvenile idiopathic arthritis (JIA) is the most common chronic inflammatory rheumatic disease of childhood and one of the leading causes of acquired childhood disability. It is a heterogeneous group of autoimmune disorders characterized by persistent arthritis of unknown cause beginning before the age of 16 years and lasting for at least six weeks after exclusion of other causes of chronic arthritis, including infections, malignancies, connective tissue diseases, and hematological disorders such as sickle cell disease.

Inflammatory musculoskeletal conditions comprise a diverse group of disorders characterized by inflammation affecting joints, peri-articular structures, muscles, tendons, ligaments, bursae, fascia, and connective tissues. These conditions may result from autoimmune disease, crystal deposition, infection, trauma, metabolic disorders, or reactive inflammatory processes.

Necrotizing fasciitis is a rapidly progressive, life-threatening soft tissue infection characterized by extensive necrosis of the deep fascia, subcutaneous tissues, and surrounding soft tissues, with secondary involvement of the skin and underlying muscles.
