Question 10

Concave

Answer 10

bone that is rounded inwards

Question 11

Convex

Answer 11

joint that is rounded outwards

Question 12

Kaltenborn Convex-Concave Rule

Answer 12

used in identifying the direction of limitation and subsequently the direction that treatment and glide should be applied

Question 13

Convex-on-Concave

Answer 13

the roll and glide occur in the opposite direction

Eg; hip or talocrural joint

Question 14

Concave-on-Convex:

Answer 14

the roll and the glide takes place in the same direction

EG: 1st MCP or Radioulnar joint

Question 15

Which way does 1st MTP glide occur

Answer 15

• 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.

Question 16

Which way does Talocrural glide occur

Answer 16

• Convex talus moves on the concave tibia
• Roll and glide occur in opposite directions.

Question 17

Which way does Patellofemoral Glide occur

Answer 17

• Convex patella moves on the concave femoral trochlea
• Patella glides inferiorly with knee flexion and superiorly with knee extension.

Question 18

Which way does Glenohumeral glide occur

Answer 18

• Convex humeral head moves on the concave glenoid fossa
• Roll and glide occur in opposite directions.

Question 19

Which way does Radiocarpal glide occur

Answer 19

• Convex carpal bones (scaphoid and lunate) move on the concave radius and articular disc
• Roll and glide occur in opposite directions.

Question 20

Which way does Tibiofemoral glide occur

Answer 20

• Concave tibial plateau moves on the convex femoral condyles.
• Roll and glide occur in the same direction
