What are the two types of articular surfaces
Ovoid
Sellar/saddle
In which direction do surfaces move in an avoid articular surface
In the same direction (either all convex or all concave)
How are concave and convex surfaces in relation to one another in sellar/saddle surfaces
Convex and concave surfaces at right angles of one another
T/F articulating surfaces are always perfectly congruent
False, they aren’t always perfectly congruent
What are the two types of diarthrosis synovial joints
Anatomical and mechanical
Diarthrosis synovial anatomical
- Simple
1 joint space / 1 capsule - Compound
>1 joint space, division made by meniscus or articular disc
Diarthrosis synovial compound
- Simple
1-3 axes - Compound
>3 axes
Axes are not at right angles to one another
Flat joint surface
What are the 5 joint positions
- Zero position
- Resting position (loose-packed position)
- Actual (momentary) resting position
- Nonresting position
- Closed-packed position
How do you find the zero position
- The starting point of any ROM
- Use of a goniometer
How do you find the resting position (loose-packed)
Most lax position for periarticular structures
Most often patients position of comfort:
- most relaxed
- Least muscle tension
In which position is there subtle joint dysfunction
nonresting position
T/F in the nonresting position, there is LESS joint play present and requires more skill for mobilization
True
What rotation/ translation occurs on the bone?
Rotations: curved angular movement around axis
What rotation/translation occurs at the joint
Rotation: rolling/gliding
Translations: Traction, compression, gliding
What is the glide test
You apply all gliding movements at the affected joint to determine restrictions
