Hand Injuries: General or unspecified injuries to the hand.Accidents, Occupational: Unforeseen occurrences, especially injuries in the course of work-related activities.Finger Injuries: General or unspecified injuries involving the fingers.Amputation, Traumatic: Loss of a limb or other bodily appendage by accidental injury.Occupational Injuries: Injuries sustained from incidents in the course of work-related activities.Injury Severity Score: An anatomic severity scale based on the Abbreviated Injury Scale (AIS) and developed specifically to score multiple traumatic injuries. It has been used as a predictor of mortality.Wrist Injuries: Injuries to the wrist or the wrist joint.Hand: The distal part of the arm beyond the wrist in humans and primates, that includes the palm, fingers, and thumb.Tenosynovitis: Inflammation of the synovial lining of a tendon sheath. Causes include trauma, tendon stress, bacterial disease (gonorrhea, tuberculosis), rheumatic disease, and gout. Common sites are the hand, wrist, shoulder capsule, hip capsule, hamstring muscles, and Achilles tendon. The tendon sheaths become inflamed and painful, and accumulate fluid. Joint mobility is usually reduced.Tendon Injuries: Injuries to the fibrous cords of connective tissue which attach muscles to bones or other structures.Wounds and Injuries: Damage inflicted on the body as the direct or indirect result of an external force, with or without disruption of structural continuity.Brain Injuries: Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.
