Q

Extensor tendon compartments

A

of the wrist are anatomical tunnels on the back of the wrist that contain tendons of muscles that extend (as opposed to flex) the wrist and the digits (fingers and thumb). The extensor tendons are held in place by the extensor retinaculum.

Q

Fibrocartilage

A

cartilage that contains fibrous bundles of collagen, such as that of the intervertebral disks in the spinal cord.

26
Q

Flexion

A

the action of bending or the condition of being bent, especially the bending of a limb or joint.

27
Q

Flexor Carpi Radialis

A

a muscle of the human forearm that acts to flex and (radial) abduct the hand.

28
Q

FOOSH

A

Acronym for fall onto outstretched hand.

29
Q

Glenoid

A

The glenoid cavity or glenoid fossa of scapula is a part of the shoulder. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula.

30
Q

Humerus

A

the bone of the upper arm or forelimb, forming joints at the shoulder and the elbow.

31
Q

Hyaline cartilage

A

a translucent bluish-white type of cartilage present in the joints, the respiratory tract, and the immature skeleton.

32
Q

Impingement

A

a clinical syndrome which occurs when the tendons of the rotator cuff muscles become irritated and inflamed as they pass through the subacromial space

33
Q

Intra-articular fracture

A

a bone fracture in which the break crosses into the surface of a joint. This always results in damage to the cartilage.

34
Q

Labrum

A

a structure corresponding to a lip, especially the upper border of the mouthparts of a crustacean or insect.

35
Q

Ligamentotaxis

A

a technique of using continuous longitudinal force (distraction) in order to bring fracture fragments more closely together.

36
Q

Mal-union

A

when a fractured bone doesn’t heal properly.

37
Q

Mason classification

A

used to classify radial head fractures and is useful when assessing further treatment options 1-2. type I: non-displaced radial head fractures (or small marginal fractures), also known as a “chisel” fracture. type II: partial articular fractures with displacement

38
Q

Metacarpals

A

any of the five bones of the hand.

39
Q

Metaphyseal fracture

A

is the narrow portion of a long bone between the epiphysis and the diaphysis. It contains the growth plate, the part of the bone that grows during childhood and as it grows, it ossifies near the diaphysis and the epiphyses.

40
Q

Neutralization plate

A

a metal plate used for the internal fixation of a bone fracture to neutralize the forces producing displacement.

41
Q

Non-displaced

A

the bone cracks either part or all of the way through, but does move and maintains its proper alignment.

42
Q

Olecranon

A

the bony prominence of the elbow, on the upper end of the ulna.

43
Q

Osteopenia

A

reduced bone mass of lesser severity than osteoporosis.

44
Q

Percutaneous fixation

A

technique used by orthopedic surgeons for the stabilization of unstable fractures.

45
Q

Pronation

A

refers to the natural side-to-side movement

46
Q

Pronator quadratus

A

is a square shaped muscle on the distal forearm that acts to pronate the hand

47
Q

Radial head

A

the most proximal aspect of the radius bone.

48
Q

Radial notch

A

is a narrow, oblong, articular depression on the lateral side of the coronoid process; it receives the circumferential articular surface of the head of the radius.

49
Q

Range of motion

A

The full movement potential of a joint, usually its range of flexion and extension

50
Q

Retinaculum

A

refers to any region on the body in which tendon groups from different muscles pass under one connective tissue band

51
Q

Rotator cuff

A

a capsule with fused tendons that supports the arm at the shoulder joint and is often subject to athletic injury.

52
Q

Rotator cuff arthropathy

A

(or shoulder arthritis with a large rotator cuff tear) can lead to progressive destruction of the bone of the arm bone (humeral head) and the socket of the shoulder blade (glenoid part of the scapula).

53
Q

Scapula

A

technical term for shoulder blade.

54
Q

Smith’s fracture

A

fractures of the distal radius with associated palmar angulation of the distal fracture fragment.

55
Q

Subchondral

A

the layer of bone just below the cartilage in a joint. the -chondral refers to cartilage, while the prefix sub means below.

56
Q

Supination

A

rotation of the forearm and hand so that the palm faces forward or upward;

57
Q

Surgical neck (humerus)

A

is a constriction below the tubercles of the greater tubercle and lesser tubercle, and above the Deltoid Tuberosity. It is much more frequently fractured than the anatomical neck of the humerus.

58
Q

Translation

A

the process of moving something from one place to another.

59
Q

Transverse carpal ligament

A

is a fibrous band on the palmar side of the hand near the wrist. It arches over the carpal bones of the hands, covering them and forming the carpal tunnel.

60
Q

Trochlear notch

A

is a large depression in the upper extremity of the ulna that fits the trochlea of the humerus (the bone directly above the ulna in the arm) as part of the elbow joint. It is formed by the olecranon and the coronoid process.

61

A

relating to the palm of the hand or the sole of the foot.
