Chapter 8 - Musculoskeltal System Flashcards
Flexor muscle
Causes flexion, bending of a limb or body part
Extensor muscle
Causes straightening of a limb or body part
Adductor muscle
Moves a body part towards the midline of the body
Abductor
Moves a body part away from the midline of the body
Pronator muscle
Turns a part downward or backwards by rotating
Supinator muscle
Turns a part upward or forward by rotation
Colle’s fracture
Fracture of the wrist at the distal radius. Sometimes the ulnar styloid is also involved
Smith’s fracture
Similar to colle’s fracture but the bones are displaced toward the palm.
Jones fracture
Stress fracture of the fifth metatarsal of the foot
Salter-Harris fracture
An epiphyseal plate fracture. Common injury in children
Dupuytren’s fracture
Fracture of the distal fibula with rupture of the distal tibiofibular ligaments and lateral displacement of the talus.
Monteggia’s fracture
Fracture of the proximal third of the ulna with associated dislocation of the radial head.

Chapter 13 Diseases of the Musculoskeletal System, Chapter 18 Signs, Symptoms, Abnormal Clinical Findings, Chapter 19 Injury, Poisoning, and other consequences of external causes.
Arthropathies
Arthropathy is a pathology or abnormality of a joint. Arthritis conditions are listed here. Verify if underlying disease is also coded.
Rheumatoid arthritis
Autoimmune disease involving the joints. Coded based on presence with other conditions like splenoadenomegaly, lung disease, presence of rheumatoid factor. Symmetrical inflammation
Osteoarthritis
Most common joint disorder. Gradual onset of pain, stiffness, and swelling. Documentation must include whether it’s primary, secondary, post traumatic, site, and laterality.
Bucket handle tear
Inside portion of a meniscus tears off but the sides stay attached creating what looks like a bucket handle.
Systemic Lupus Erythematosus
Lupus. Autoimmune inflammatory connective tissue disease that affects multiple body systems. Most common in women with no known cause. Manifestations are included in the code
Spondylosis
Osteoarthritis of the spine.
Spondylitis
Inflammation of the spine
Ankylosis
Stiffening of a joint
Ankylosing spondylitis
Stiffening and inflammation of the spine. More common in men than women.
Spinal stenosis
Narrowing of the spinal canal. Causes pressure on the nerves causing pain, paresthesia, weakness, or diminished reflexes. Coded based on region of the spine. Neurogenic claudication is included in this code
Neurogenic claudication
Pain in the lower back, buttock, thigh, and leg. Precipitated by walking and prolonged standing. Relieved by change in position or flexion of the waist and not by rest.
Rheumatism
Nonspecific reference to any painful disorder of joints, muscle, or connective tissue. Codes from M65-M67
Synovitis
Condition that causes joint tenderness and swelling. Can be very painful. Synovial lining becomes inflamed.
Tenosynovitis
When the protective lining of the tendon sheath becomes inflamed.
Trigger finger
Condition that causes the finger to snap straight when extending the hand.
Ganglion of the joint or tendon
Benign cyst that occurs above a tendon or on a joint. Most common in the hands and wrist.
Capsulitis
Inflammation of the tissues surrounding a joint.
Adhesive capsulitis
Reduction in mobility of the shoulder. Often called frozen shoulder.
De Quervain’s Syndrome
Radial styloid tenosynovitis. Caused by repetitive motion of the wrist.
Bursitis
Inflammation of the bursa.
Compartment syndrome
Compression of the nerves, muscles, and blood vessels in an enclosed space. Can be traumatic and non traumatic.
Osteomyelitis
Inflammation of the bone and bone marrow caused by infection. Based on acute, subacute, chronic, and by site and laterality. Need to code infectious agent and major osseous effect.
Osteochondrosis
Causes degeneration of ossification centers of the epiphyses of the bone. Often seen in children experiencing periods of rapid growth.
Osteoporosis
Bone disease that decreases bone density. Coded based on type, and with or without pathologic fracture.
Pathologic fracture
Fracture caused by disease such as an infection or tumor leading to weakness in the bone. Most often osteoporosis. Verify if codes are needed for underlying condition.
Lordosis
Curving of the lumbar spine
Kyphosis
Curving of the thoracic spine.
Scoliosis
Curvature of the spine to the left or right.
Sprain
Involves non-contractile tissue (ligaments)
Strain
Involves contractile tissue (muscle and tendons)
Nursemaid’s elbow
Partial dislocation of the elbow, or proximal radial head dislocation. Seen in children and caused by sudden pull on child’s arm or hand.
Closed fracture
Bone has not broken the skin. Unspecified fractures are coded as closed
Open fracture
Fracture where the bone has broken through the skin.
