Block 1 Flashcards
(119 cards)
Freely movable, bones do not touch each other, bones covered by articular cartilage
Surrounding the membrane is a joint capsule
Synovial Joint
Separated by a synovial cavity
Synovial membrane lines the cavity and secretes synovial fluid
Slightly movable; at the center of each disc is a nucleus pulposus
Examples are intervertebral discs, ribs-sternum, epiphyseal plates of long bones
Cartilaginous
Fibrocartilaginous discs separate the bony surfaces
Immovable; examples are sutures, distal talofibular joint, teeth/socket
Fribrous
Bones are connected by fibrous connective tissue
Intervening layers of fibrous tissue hold the bones together
Tibiofibular (KoJ)
Syndesmosis
Skull (KoJ)
Suture
Vertebrae (KoJ)
Symphysis
Rib (KoJ)
Synchondrosis

Radioulnar (KoJ)
Gliding
Elbow (KoJ)
Hinge
Hip (KoJ)
Ball and socket
CMC - Thumb (KoJ)
Saddle
Atlantoaxial (KoJ)
Pivot
When gathering social history, what is the one big thing to ask that impedes bone healing (orthopedics)?
Smoking
Approach for the musculoskeletal exam should be systematic after first assessing general appearance body proportions, and ease of movement (walk, sitting, etc.)…
1) Inspection
2) Palpation of bony and soft tissue landmarks
3) AROM/PROM
4) Neurovascular examination
5) Special maneuvers
6) Further studies (x-ray, MRI, blood studies, etc.)
Acute involvement of only 1 joint suggests…
Trauma, septic arthritis, or gout
Rheumatoid arthritis typically involves…
Several joints, symmetrically distributed
What is a fasciculation and how does it differ from a tremor?
The muscle starts to tremor without any movement (important during strength testing)
Patient bends arm, starts to twitch and/or tremor but no movement
Tremor alone has slight movement
During palpation of bony and soft tissue landmarks, what are you looking for?
Tenderness, nodules (popliteal cysts behind knee), crepitus, swelling (effusion or synovitis), warmth (arthritis, tendinitis bursitis, osteomyelitis), redness (erythema)
How do you test strength?
Asking patient to move actively against your resistance
What is the big difference for the grade of strength between 2 and 3?
Grade 2: active movement of body part with gravity eliminated (parallel to earth)
Grade 3: active movement against gravity only
TMJ is the most active joint in the body. Where does it lie between?
External Acoustic Meatus and the Zygomatic Arch
What muscle is responsible for opening the jaw? (Depression)
External Pterygoid
What muscles are responsible for closing the jaw? (Elevation/retraction)
Masseter, temporalis, and internal pterygoids
