Chapter 8 - Musculoskeletal System Flashcards
ORIF
open reduction internal fixation
Flexor
Causes flexion or bending of a limb or body part
Extensor
Causes straightening of a limb or body part.
Adductor
Moves a part of the body towards the midline of the body.
Abductor
Moves a part of the body away from the midline of the body.
Pronator
Turns a part downward or backward by rotating.
Supinator
Turns a part upward or forward by rotating.
Colles’ Fracture
A fracture of the wrist at the distal radius. Sometimes the ulnar styloid also is involved.
Smith’s Fracture
Similar to a Colles’ fracture, except the bones are displaced toward the palm.
Jones Fracture
A stress fracture of the fifth metatarsal of the foot.
Salter-Harris Fracture
An epiphyseal plate fracture; a common injury seen 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.
Tendons vs ligaments
Tendons attach muscles to bone, and ligaments attach bones to other bones.
Dorsopathies
Disorders affecting the spinal column
Spondylosis
Osteoarthritis of the spine
Enthesopathies
Disorders of ligaments
Compartment Syndrome
Compression of muscles, nerves and blood vessels within an enclosed space. Leads to muscle and nerve damage.
Osteomyelitis
Inflammation of the bone and bone marrow caused by infection
Sprain vs strain
A sprain involves the noncontractile tissue (ligament) and a strain involves the contractile tissue (muscle or tendon)
Nursemaid’s Elbow
A partial dislocation of the elbow, or proximal radial head dislocation. It is most common in small children and is caused by a sudden pull on the child’s arm or hand.
Subluxation
a partial or incomplete dislocation of the joint.
Dislocation
a complete dislocation of the joint.
Comminuted Fracture
The bone is crushed or splintered into several pieces.
Compression Fracture
The bone is compressed onto another bone caused by trauma or osteoporosis and common in vertebrae.
Depressed Fracture
Fracture typically resulting from blunt force trauma to the skull. There is a portion of the bone that is pushed in.
Greenstick Fracture
The bone is broken on one surface and bent on the other (think of the way a “green” twig will break when bent too far); this fracture occurs in children before the bones have hardened.
Impacted Fracture
One part of a bone is driven forcefully into another.
Simple Fracture
The bone is broken in only one place.
Torus or Incomplete Fracture
One side of the bone buckles. This is mostly common in children because of their softer bones.
AC
acromioclavicular
ACL
anterior cruciate ligament
AFO
ankle-foot orthosis
AKA
above-knee amputation
ANA
antinuclear antibody
BKA
below-knee amputation
C-Spine
cervical spine
CMC
carpometacarpal (joint)
