FINALS: Arthroplasty Flashcards
(35 cards)
Q: What is hemiarthroplasty?
A: Partial hip replacement; replaces femoral head only.
Q: Difference between unipolar and bipolar hemiarthroplasty?
Unipolar: One-piece, for elderly fractures.
Bipolar: Two-piece, better motion, for younger or active patients.
Q: Indications for total hip arthroplasty (THA)?
A: End-stage osteoarthritis, AVN, inflammatory arthritis, ankylosis.
Q: What is press-fit or cementless fixation?
A: Bone grows into a rough prosthetic surface; used in younger patients.
Q: What are the parts of a THA implant?
A: Femoral stem, acetabular component, and liner (plastic, ceramic, metal).
Q: Components of total knee arthroplasty (TKA)?
A: Femoral, tibial, and often patellar components.
Q: What are the parts of a THA implant?
A: Femoral stem, acetabular component, and liner (plastic, ceramic, metal).
Q: TKA rehab goals in first 2 weeks?
A: Achieve 0–90° flexion, use CPM, begin weight-bearing (depends on fixation).
Q: What is hip resurfacing arthroplasty?
A: Reshapes and caps joint surfaces, preserves bone; best for younger patients.
Q: What is hip resurfacing arthroplasty?
A: Reshapes and caps joint surfaces, preserves bone; best for younger patients.
Q: When is cemented fixation used?
A: In older adults with poor bone quality or previous radiation exposure.
Q: What is unicompartmental knee arthroplasty (UKA)?
A: Replacement of one joint compartment, usually medial.
Q: Indications for knee arthroplasty?
A: Advanced OA or inflammatory arthritis with functional limitations.
Q: Posterolateral hip precautions?
A: Avoid hip flexion >90°, adduction, internal rotation, and leg crossing.
Q: Weight-bearing protocol for cementless TKA?
A: TDWB for 6 weeks, then progress.
Q: Types of TKA constraint?
Unconstrained: Relies on soft tissues
Semiconstrained: Corrects moderate deformity
Fully constrained: For severe instability
Q: Weight-bearing protocol for cemented TKA?
A: WBAT with walker.
Q: What is reverse shoulder arthroplasty?
A: Reverses ball and socket orientation for rotator cuff deficiency.
Q: Rehab position post-shoulder replacement?
A: Immobilized in airplane splint (80° flex, 70° abduction, 5° IR).
Q: Indications for total shoulder arthroplasty?
A: Arthritis, AVN, or fractures of proximal humerus.
Q: Indications for elbow arthroplasty?
A: Pain, deformity, instability, failed surgeries, tumor resection.
Q: When can active ROM start post-shoulder arthroplasty?
A: Around 6 weeks if the rotator cuff is intact.
Q: Goal of trapezio-metacarpal arthroplasty?
A: Pain relief in thumb base arthritis; FWB at ~12 weeks.
Q: Rehab after elbow replacement?
Start ROM 3–5 days post-op (if triceps spared).
Avoid valgus/varus stress for 6–8 weeks.
