Chapter 15: Musculoskeletal System Question Answer Abduction Movement away from the midline. Achondroplasia Defect in the formation of cartilage at the epiphyses of long bones, producing a form of dwarfism. Acromioclavicular Dislocation Disruption of the articulation between the acromion and the clavicle. Also known as a shoulder separation. Adduction Movement toward the midline. Amyotrophic Lateral Sclerosis Degeneration of nerves in the spinal cord and lower region of the brain cause muscle paralysis. Also known as Lou Gehrig Disease. Ankylosing Spondylitis Chronic, progressive arthritis with stiffening of joints, primarily the spine. Bilateral sclerosis of the sacroiliac joints is a diagnostic sign. Ankylosis Immobility of a joint. Antinuclear Antibody Test (ANA) Detects an antibody present in serum of patients with systemic lupus erythematosus (SLE). Arthritis Inflammation of joints. Arthrocentesis Removal of fluid from a joint space with a needle. Arthrodesis Fusion of two bones. Arthrography X-ray of a joint, or x-ray of the synovial joint after injection with contrast. Arthroplasty Surgery to reshape, reconstruct, or replace a joint. Arthroscopy Direct joint visualization using an arthroscope. Arthrotomy Cutting into a joint. Articulation A joint. Atrophy Decrease in the size of an organ or tissue. Bone Density Test Low-energy x-ray detection of bones of the spinal column, pelvis, and wrist to measure bone mass. Also known as bone 1

Chapter 15: Musculoskeletal System densitometry and dual-energy x-ray absorptiometry (DEXA) Bone Scan Uptake of a radioactive substance is measured in the bone using a special scanning device. Areas of increased uptake may be signs of tumors, infection, inflammation, and stress fractures. Boney Ankylosis Abnormal union of the bones at a joint. Bunion Swelling of the metatarsophalangeal joint near the base of the big toe, accompanied by soft tissue and underlying bone build up at the distal/medial aspect of the first metatarsal. Bursitis Inflammation of the bursa. Carpal Tunnel Syndrome Compression by a wrist ligament of the median nerve as it passes between the ligament and the bones and tendons of the wrist. Chemonucleolysis Injection of a disk-dissolving enzyme (ex. chymopapain) into the center of a herniated disk in an effort to relieve pressure on the compressed nerve or spinal cord. Chondromalacia Patella Softening of the articular cartilage of the patella, resulting in pain, a grating sensation, and mechanical “catching” behind the patella. Chondromalacia Softening of the articular cartilage, usually involving the patella. Chrondoma Slow-growing, painless cartilage tumor, which may occur anywhere there is cartilage. Colles Fracture
