Elbow Flashcards
Humeroulnar/Humeroradial: Classification
Structure: synovial
Function: diarthrotic
Subtype: hinge
Axis: uniaxial
Humeroulnar/Humeroradial: ROM
Flexion 135º
Extension up to 5º
Humeroulnar Joint: Resting position
70º flexion, 10º supination
Humeroulnar Joint: Closed-pack position
Full extension and supination
Humeroulnar Joint: Capsular pattern
Flexion more than extension
Humeroradial Joint: Resting position
Full extension and supination
Humeroradial joint: closed pack position
90º flexion 5º supination
Humeroradial joint: capsular pattern
flexion more than extension
Humeroulnar/Humeroradial: Articular surfaces
Humerus: capitulum and trochlea (convex)
Radius: articular surface of the head (concave)
Ulna: trochlear notch (concave)
=> concave on convex
Humeroulnar/Humeroradial: ligaments
Radial collateral ligament
Ulnar collateral ligament
Humeroulnar: Joint mob’s
Traction/distraction (flexion/extension)
Distal glide
Radial glide
Ulnar glide
Humeroradial: Joint mob’s
Traction/distraction
Dorsal glide
Joint compression
Proximal Radioulnar Joint: Classification
Structure: synovial
Subtype: pivot
Function: diarthrotic
Axis: uniaxial
Proximal Radioulnar Joint: ROM
Pronation 70-90º
Supination 90º
Proximal Radioulnar Joint: Resting position
35º flexion, 70º supination
Proximal Radioulnar Joint: Closed pack position
full supination/pronation
Proximal Radioulnar Joint: Capsular pattern
supination = pronation
Proximal Radioulnar Joint: Articular surfaces
Articular surface of radius bone (Convex)
Radial notch of ulna (concave)
=> convex on concave
Proximal Radioulnar Joint: ligaments
annular
oblique cord
interosseous membrane
Proximal Radioulnar Joint: Joint Mob’s
dorsal/volar glides (pronation/supination)
