Total Hip Arthroplasty (THA) - 2 - Femoral Component

In Part 2 of our Total Hip Arthroplasty (THA) series, we explore the biomechanics and design concepts behind Femoral Components, focusing on hip center of rotation, offset restoration, and trunnion-head modularity. Key concepts discussed in this video: • The Lever Arm Principle in hip biomechanics (Single-leg stance, gait, and abductor mechanics). • Charnley’s Concept in THA: Deepening the acetabulum, trochanteric osteotomy, and why modern practice moved away from it. • Modern anatomical restoration: Vertical height, medial offset, and neck version. • Under-restored vs. Over-restored Femoral Offset: Impact on abductor lever arm, joint reaction force (JRF), polyethylene wear, impingement, and varus torque/stress shielding. • Morse Taper / Trunnion design (12/14 tapers) and mismatch risks. • Modular head options, neck length adjustments, and the clinical implications of skirted heads . Essential viewing for orthopedic surgery residents, arthroplasty fellows, and candidates preparing for post-graduate orthopedic exams (FRCS Orth, EBOT, SICOT, and Board examinations). #TotalHipArthroplasty #HipArthroplasty #THA #FemoralComponent #FemoralOffset #HipBiomechanics #OrthopedicSurgery #Arthroplasty #MorseTaper #Orthopedics
