CTP: Suggested Study Strategy
Frequently Asked Questions
What is a test socket and why is it used?
A test socket (check socket) is a clear thermoplastic socket — typically PETG or polypropylene vacuum-formed over the positive mold — used to assess fit BEFORE committing to a definitive (laminated) socket. The clarity allows visualization of pressure points, soft tissue contact, and alignment. Modifications are made to the positive mold based on the test fitting, then the definitive socket is laminated.
How is a definitive prosthetic socket laminated?
Definitive socket lamination over modified positive mold: (1) PVA bag inner layer (release agent); (2) nylon stockinette layers; (3) reinforcement fabrics — carbon fiber, fiberglass, perlon — strategically placed; (4) outer PVA bag with vacuum drawn; (5) acrylic or polyester resin poured into bag, drawn through layup by vacuum; (6) cure 8-12 minutes for acrylic; (7) trim, smooth, attach hardware.
What is the standard TF socket alignment?
Transfemoral bench alignment starting points: 5° initial socket flexion (anterior tilt), 5° adduction (medial tilt), and slight external rotation (matching contralateral toe-out). These initial angles are then refined through static (standing) and dynamic (gait) alignment with the patient. The TKA line (trochanter-knee-ankle) should be vertical in the sagittal plane through the trochanter.
How should I study for ABC CTP?
Plan 50-80 hours over 6-10 weeks. Focus weighted study on Fabrication Techniques (25%) and Prosthetic Components (20%). Master test socket forming, definitive socket lamination, knee/foot/pylon assembly, alignment hardware, and OSHA resin handling. Hands-on socket fabrication and alignment time is essential.
