strain and sprain involves the ligaments
A traumatic injury to a joint involving the ligaments is graded based on the severity of the injury. Grade 1 is a mild sprain with slight stretching or microscopic tearing of the ligament. Grade 2 is a moderate sprain with partial tearing of the ligament. Grade 3 is a severe sprain with complete tearing of the ligament, resulting in joint instability.
Some examples of injuries that can occur suddenly during activities include sprains (stretching or tearing of ligaments), strains (overstretching or tearing of muscles or tendons), fractures (broken bones), dislocations (bone out of its normal position), and concussions (brain injury from a blow to the head).
A sprain is a stretching or tearing of ligaments that connect bones at a joint. It can cause pain, swelling, and limited range of motion in the affected joint. In severe cases, a sprain may require medical treatment and rehabilitation to heal properly.
A hyperextended thumb occurs when the thumb is bent backwards beyond its normal range of motion. This can result in stretching or tearing of the ligaments supporting the thumb joint, causing pain, swelling, and instability in the thumb. Treatment may involve rest, ice, splinting, and physical therapy.
