Bone metastasis

Transfer of disease or cancerous lesions from one organ or part that may not be directly connected

Bursitis

Inflammation of the bursae or fluid filled sacs that enclose the joints

Carpal tunnel syndrome

Common painful disorder of the wrist and hand that results from compression of the median nerve as it passes through the center of the wrist

Barton fracture

Fracture and dislocation of the posterior lip of the distal radius involving the wrist joint.

Bennett fracture

Fracture of the base of the first metacarpal bone, Extending into the carpometacarpal joint, Complicated by subluxation with some posterior displacement.

Boxer fracture

Transverse fracture that extends through the metacarpal neck

Most commonly seen in the fifth metacarpal

Colles fracture

Transverse fracture of the distal radius in which the distal fragment is displaced posteriorly.

Smith fracture

Reverse of Colles Fracture, Or transverse fracture of the distal radius with the distal fragment, displaced anteriorly.

Joint effusion

Refers to accumulated fluid in the joint cavity

Osteoarthritis

Non-inflammatory joint disease characterized by gradual deterioration of the articular cartilage with hypertrophic bone formation.

Osteomyelitis

Local or generalized infection of bone or bone marrow that may be caused by bacteria introduced by trauma or surgery.

Osteopetrosis

Hereditary disease marked by abnormally dense bone

Osteoporosis

Refers to reduction in the quantity of bone or atrophy of skeletal tissue

Paget disease

Common chronic skeletal disease, Bone destruction followed by a reparative process of overproduction of dense, soft bones that tend to fracture easily.

Rheumatoid arthritis

Chronic systemic disease with inflammatory changes throughout the connective tissues.

Schapolunate ligament tear

Involves the ligament that connects the scaphoid to the lunate bone. Tears are evident by a widening of the space between the scaphoid and lunate of 3 to 4 mm or greater.

Skiers thumb

Sprain or tear of the ulnar collateral ligament of the thumb near the MCP joint of the hyperextended thumb.

Chondrosarcoma

Slow growing malignant tumor of the cartilage

Enchondroma

Slow growing benign, cartilaginous tumor, most often found in small bones of the hands and feet.

Who is rheumatoid arthritis most common in

AP wrist

What will best demonstrate the wrist joint and enter carpal spaces?

Scaphoid fat stripe

Elongated and slightly convex in shape and is located between the radial collateral ligament and adjoining muscle tendons immediately lateral to the scaphoid.

Pronator fat stripe

Visualized approximately 1/4 inch from the anterior surface of the radius

Anterior fat pad

Formed by the super imposed, coronoid and radial pads

Seen as a slightly radiolucent teardrop shape located just anterior to the distal humerus.

Posterior fat pad

Located deep within the olecranon fossa and normally is not visible on a negative elbow examination

Supinator fat stripe

Long, thin stripe just anterior to the proximal radius.
