  2. II II II 5-7° II - PARALLEL MEDIAL WALL MEDIAL FOOTLINE LINE OF PROGRESSION A 20-22 mm 1/2 AP 1/2 AP P 1/2 ML 1/2 ML M L TT INITIAL ALIGNMENT: TRANSVERSAL VIEW

  3. L 5 - 10 mm 0 mm TT INITIAL ALIGNMENT: ANTERIOR VIEW MEDIO-LATERAL PLACEMENT OF PP CUP LONG STUMP: MORE THAN 2/3 OF THE ANATOMICAL LENGTH; NORMAL POSITION: VARUM PHYSIOLOGIQUE MEDIUM STUMP: FROM 1/3 TO 2/3 OF THE ANATOMICAL LENGTH; NORMAL POSITION: NEUTRAL SHORT STUMP: LESS THAN 1/3 OF THE ANATOMICAL LENGTH; NORMAL POSITION: VALGUM PHYSIOLOGIQUE M 5 - 10 mm

  4. 20- 25 mm TT INITIAL ALIGNMENT: MEDIO-LATERAL VIEW ANTERO-POSTERIOR PLACEMENT OF PP CUP LONG STUMP: FLEXION : 0° - 5° MEDIUM STUMP: FLEXION : 5° - 7° SHORT STUMP: FLEXION : 10° - 15 ° 30- 35 mm 20 mm

  5. NEUTRAL HIGH HEEL = PLANTAR FLEXION NO HEEL = DORSAL FLEXION TT INITIAL ALIGNMENT: MEDIO OR LATERAL VIEW VERTICALITY OF THE TUBE ACCORDING TO HEEL HEIGHT

  6. NEUTRAL PRONATION = VALGUM SUPINATION = VARUM TT INITIAL ALIGNMENT: ANTERIOR VIEW VERTICALITY OF THE TUBE ACCORDING TO SOLE CONDITION

  7. PTB BAR IS HORIZONTAL POSITION IS NEUTRAL CUP IS HORIZONTAL HEIGHT IS CORRECT TUBE IS VERTICAL PLUMBLINE IS IN THE CENTER TT INITIAL ALIGNMENT: ANTERIOR & POSTERIOR VIEW MEDIUM STUMP

  8. PTB BAR IS HORIZONTAL TILT OF THE SOCKET CORRESPONDS WITH THE PHYSIOLOGICAL VARUM OF THE STUMP LATERALITY 5-10mm CUP IS HORIZONTAL TUBE IS VERTICAL FOOT 5-10 mm MEDIAL TT INITIAL ALIGNMENT: ANTERIOR & POSTERIOR VIEW LONG STUMP

  9. PTB BAR IS HORIZONTAL TILT OF THE SOCKET CORRESPONDS WITH THE PHYSIOLOGICAL VALGUM OF THE STUMP CUP IS HORIZONTAL MEDIALISATION 5-10mm TUBE IS VERTICAL FOOT 5-10 mm LATERAL TT INITIAL ALIGNMENT: ANTERIOR & POSTERIOR VIEW SHORT STUMP

  10. MEDIUM STUMP 1/2 AP • Anteriorisation of the socket is • according to stump length: • 20 mm for long / very long stump • 20 to 25 mm for medium stump • 30 to 35 for short stump FLEXION = 5° CUP IS HORIZONTAL TUBE IS VERTICAL 1/3 1/3 1/3 TT INITIAL ALIGNMENT: LATERAL VIEW
