Concave Convex manual therapy Flashcards
Ankle joint (Talocrural) Concave and convex
Talus - Convex
Tibial mortise - concave
Knee joint (Tibiofemoral) concave and convex
Femoral condyles - Convex
Tibial plateai - Concave
Hip joint (acetabulofemoral) Concave and convex
Femoral head - Convex
Acetabulum - Concave
Shoulder joint (Glenohumeral) concave and convex
Humeral head - Convex
Glenoid fossa - Concave
Elbow joint (Humeroulnar) or (radioulnar) Concave and convex
Trochlea of humerus - Convex
Trochlear notch of ulna - Concave
Wrist joint (Radiocarpal) Concave and convex
Proximal row of carpals - Convex
Radius and articular disc - Concave
Patellofemoral joint concave and convex
Patella - Convex
Femoral trochlea - Concave
1st MTP Joint (Big toe) Concave and convex
Metatarsal head - Convex
Base of proximal phalanx - Concave
1ST MCP joint (thumb) Concave and convex
Metacarpal head - Convex
Base of proximal Phalanx - Concave
Concave
bone that is rounded inwards
Convex
joint that is rounded outwards
Kaltenborn Convex-Concave Rule
used in identifying the direction of limitation and subsequently the direction that treatment and glide should be applied
Convex-on-Concave
the roll and glide occur in the opposite direction
Eg; hip or talocrural joint
Concave-on-Convex:
the roll and the glide takes place in the same direction
EG: 1st MCP or Radioulnar joint
Which way does 1st MTP glide occur
- Concave base of the proximal phalanx moves on the convex head of the metatarsal
- The roll and glide of the phalanx occur in the same direction.
Which way does Talocrural glide occur
- Convex talus moves on the concave tibia
- Roll and glide occur in opposite directions.
Which way does Patellofemoral Glide occur
- Convex patella moves on the concave femoral trochlea
- Patella glides inferiorly with knee flexion and superiorly with knee extension.
Which way does Glenohumeral glide occur
- Convex humeral head moves on the concave glenoid fossa
- Roll and glide occur in opposite directions.
Which way does Radiocarpal glide occur
- Convex carpal bones (scaphoid and lunate) move on the concave radius and articular disc
- Roll and glide occur in opposite directions.
Which way does Tibiofemoral glide occur
- Concave tibial plateau moves on the convex femoral condyles.
- Roll and glide occur in the same direction
