An **ACL Tear** is an injury to the anterior cruciate ligament of the knee. It is a **condition** that can cause knee instability, swelling, and functional limitation. It is commonly discussed in sports medicine, orthopedics, emergency care, and physical therapy settings. Clinicians use the term to describe a spectrum from partial fiber disruption to complete ligament rupture.

A SLAP Tear is an injury of the superior (top) part of the shoulder labrum. It is a **condition** affecting the glenohumeral (shoulder) joint and the biceps tendon anchor. It often relates to overhead sports, traction injuries, or age-related tissue change. It is commonly discussed in sports medicine, orthopedics, radiology, and rehabilitation settings.

Labral Tear means a disruption of the labrum, a ring of fibrocartilage that lines certain joints. It is a medical condition and an anatomic-pathology concept. It most commonly refers to the shoulder (glenoid labrum) or hip (acetabular labrum). In practice it is used to explain joint pain, mechanical symptoms, and instability patterns.

Shoulder Impingement is a clinical concept used to describe pain and dysfunction related to contact or compression of soft tissues around the shoulder during motion. It is most commonly discussed as a **condition** affecting the rotator cuff tendons and the subacromial bursa. In practice, it is used in outpatient orthopedics, sports medicine, primary care, and physical therapy as a framework for evaluating shoulder pain—especially with overhead activity. The term is also used in imaging interpretation and in planning conservative or surgical management pathways.

Adhesive Capsulitis is a shoulder condition that causes pain and progressive stiffness. It is commonly called “frozen shoulder” in plain language. It is a clinical diagnosis defined by restricted **active and passive** glenohumeral motion. It is commonly used in orthopedic, sports medicine, primary care, and rehabilitation settings as a framework for evaluation and management of atraumatic shoulder stiffness.

Frozen Shoulder is a shoulder condition marked by pain and a progressive loss of both active and passive range of motion. It is also called adhesive capsulitis in clinical language. It involves the glenohumeral (ball-and-socket) joint capsule and surrounding soft tissues. It is commonly used in practice as a diagnostic label when shoulder stiffness is out of proportion to imaging findings.

Rotator Cuff Tear is a condition involving disruption of one or more rotator cuff tendons in the shoulder. It ranges from partial-thickness fraying to full-thickness tendon failure with retraction. It is commonly discussed in sports medicine, orthopedics, primary care, and rehabilitation settings. Clinically, it is used as a diagnostic concept to explain pain, weakness, and loss of shoulder function.

A Compression Fracture is a fracture pattern in which bone collapses under axial load (a “squeezing” force). It is a **condition** (an injury diagnosis) most commonly discussed in the **spine**, especially the vertebral bodies. In practice, clinicians use the term to describe fracture stability, likely mechanism, and risk to the spinal canal and nerves. It is evaluated in emergency, inpatient, and outpatient musculoskeletal care using history, exam, and imaging.

Spinal Stenosis means abnormal narrowing of spaces in the spine where neural tissue travels. Spinal Stenosis is a medical condition with musculoskeletal and neurologic consequences. It is commonly discussed in orthopedic surgery, spine care, neurology, primary care, and rehabilitation settings. It is most often evaluated in patients with posture- or activity-related back/neck pain and neurologic symptoms.

Slipped Disc is a common, nontechnical term for an intervertebral disc herniation in the spine. It is best understood as a **clinical concept/condition** rather than a single, precise diagnosis. In practice, it is used to describe disc-related back or neck pain and sometimes arm or leg symptoms from nerve irritation. Clinicians often replace the term with more specific language such as **disc bulge**, **disc protrusion**, or **disc extrusion**.
