Musculoskeletal Diagnostic Imaging

Flashcards covering essential vocabulary and definitions for musculoskeletal diagnostic imaging and related conditions.

Epiphysis

The end of a long bone which connects to joints.

Metaphysis

The region between the epiphysis and diaphysis that grows during childhood.

Diaphysis

The tubular midportion of the shaft of a long bone.

CT Scan

A detailed examination of bones that can pick up fractures missed by X-rays.

MRI

Imaging technique used to evaluate soft tissues such as tendons and ligaments.

Open Reduction Internal Fixation (ORIF)

A surgical procedure used to stabilize and heal fractured bones.

Subluxation

An incomplete or partial dislocation of a joint.

Dislocation

An injury where a bone is displaced from its proper position.

Osteoarthritis

Chronic degeneration of articular cartilage, common in weight-bearing joints.

Osteoporosis

Loss of bone density over time, commonly seen in postmenopausal women.

Malignant Bone Tumors

Tumors with poorly defined margins; can disrupt cortical bone.

Benign Bone Tumors: Osteochondroma

The most common benign bone tumor, painless and usually found incidentally.

Scaphoid Fracture

Typically caused by a fall on an outstretched hand; can lead to avascular necrosis.

Colle's Fracture

Fracture of the distal radius with dorsal displacement, commonly seen in elderly.

Buckle Fracture

A type of stable fracture typically occurring in children from axial loading.

Salter Harris Fractures

Fractures of the growth plate in children, classified into five types.

Ewing's Sarcoma

A bone tumor occurring mostly in younger patients, often mimics osteomyelitis.

Rheumatoid Arthritis

A chronic autoimmune disease causing joint inflammation and destruction.

Osteomyelitis

An infection and inflammation of the bone, often due to underlying conditions.
