Capsulitis is inflammation and dysfunction of a joint capsule. Capsulitis is a clinical condition, not a single procedure or device. Capsulitis is most commonly discussed in shoulder care as adhesive Capsulitis (“frozen shoulder”). Capsulitis is also used in practice to describe capsule-driven pain and stiffness in other joints.

Joint Capsule is a normal anatomical structure that surrounds many synovial joints. It is a tough outer envelope with an inner lining that helps contain and manage joint fluid. It functions as a stabilizing and sealing component of the joint, working with ligaments, cartilage, and muscles. In clinical practice, it is commonly referenced when discussing joint stability, stiffness, effusions, and intra-articular pathology.

Wrist Dislocation is an injury where the normal alignment of the wrist joint surfaces is lost. It is a **condition** that usually follows trauma and involves bones and ligaments of the wrist. It is commonly encountered in emergency, orthopedic, sports medicine, and trauma settings. It matters because missed or delayed recognition can affect pain, motion, and nerve function.

Elbow Dislocation is a condition where the bones of the elbow joint lose their normal alignment. It is typically an acute traumatic musculoskeletal injury rather than a disease process. It most often presents in emergency, sports medicine, and orthopedic trauma settings. Clinicians use the term to guide urgent assessment of joint congruence, stability, and neurovascular status.

Ankle Dislocation is a condition where the talus loses its normal alignment within the ankle mortise. It is an acute joint-injury category problem, most often caused by trauma. It is commonly encountered in emergency, orthopedic trauma, sports medicine, and radiology settings. It is clinically important because it can threaten skin, nerves, and blood flow around the ankle.

Knee Dislocation is a condition in which the tibia and femur lose their normal alignment at the tibiofemoral joint. It usually occurs after trauma and commonly involves injury to multiple ligaments. It is clinically important because nearby arteries and nerves can be damaged at the same time. The term is used in emergency, trauma, sports medicine, and orthopedic practice to guide urgent evaluation and management.

Hip Dislocation is a condition in which the femoral head is displaced out of the acetabulum. It is most often an acute traumatic injury, but it can also occur around a hip prosthesis. Clinically, it is treated as an urgent musculoskeletal problem because the hip is a major weight-bearing joint. The term is commonly used in emergency care, orthopedics, radiology, and rehabilitation medicine.

Shoulder Dislocation is a condition in which the humeral head is displaced out of the glenoid (shoulder socket). It is most commonly a traumatic injury affecting the glenohumeral joint, but it can also occur with recurrent instability. In clinical practice, it is used as a diagnostic label that guides urgent assessment, reduction, and follow-up planning. It is frequently discussed in emergency medicine, orthopedics, sports medicine, radiology, and rehabilitation settings.

A High Ankle Sprain is a ligament injury of the distal tibiofibular syndesmosis above the ankle joint. It is a **condition** that affects ankle stability, especially during twisting and push-off activities. It is commonly evaluated in sports medicine, emergency care, and orthopedic clinics after an ankle injury. It is clinically important because it can behave differently than a typical lateral ankle sprain.

Ankle Sprain is a common musculoskeletal condition involving injury to one or more ankle ligaments. It most often follows a twisting mechanism that exceeds normal ligament tensile capacity. It is used in everyday orthopedic, sports medicine, emergency, and rehabilitation practice. Clinicians use the term to communicate injury pattern, expected associated findings, and a general care pathway.
