1

bursitis (shoulder)

inflammation of the shoulder bursa from repeated motion

2

carpal tunnel

entrapment of the median nerve as it runs through the carpal bones of the wrist; this results from repeated flexion and extension of the wrist and also from mechanical pressure against the wrist

3

cubital tunnel

entrapment of the ulnar nerve as it runs through the elbow; this can result from repeated twisting of the forearm and mechanical pressure against the elbow when you rest it on the exam table while scanning

4

deQuervain’s disease

specific type of tendonitis involving the thumb that can result from gripping the transducer

5

epicondylitis (lateral and medial)

inflammation of the periosteum in the area of the insertion of the biceps tendon into the distal humerus; this can result from repeated twisting of the forearm

6

ergonomics

the science of designing a job to fit the individual worker

7

Occupational Safety and Health Act (OSHA)

federal law passed in 1970 to ensure that every working man and woman in the nation has safe and healthful working conditions

8

rotator cuff injury

repeated motion results in fraying of the rotator cuff muscle tendons; this injury increases with age and is even more prevalent when work-related stresses are added; repeated arm abduction contributes to this injury by restricting blood flow to the soft tissues of the shoulder

9

spinal degeneration

intervertebral disc degeneration results from bending and twisting and improper seating

10

tendonitis and tenosynovitis

inflammation of the tendon and the sheath around the tendon; these conditions often occur together

11

thoracic outlet syndrome

nerve entrapment can occur at different levels, resulting in a variety of symptoms

12

trigger finger

inflammation and swelling of the tendon sheath in a finger entraps the tendon and restricts motion of the finger

13

work-related musculoskeletal disorder (WRMSD)

current term to describe occupational injury; defined as injuries that result in restricted work, days away from work, symptoms of musculoskeletal disorder that remain for 7 or more days, and musculoskeletal disorders requiring medical treatment beyond first aid
