Episode notes
Sources of Adverse Tissue Reaction
- Adverse tissue reactions come primarily from large head metal-on-metal bearings, dual modular necks, and taper corrosion.
- Although cobalt chrome heads are used less, taper corrosion remains significant in metal heads.
Thorough Hip Pain Evaluation
- Always rule out extrinsic causes of hip pain before focusing on metal-related diagnoses.
- Obtain operation reports to understand implant details and prepare for revision surgery.
Essential Workup for Painful Metal Hips
- For patients with metal heads and hip pain, perform H&P, obtain quality X-rays, inflammatory markers, serum metal ion levels, and aspirate if needed.
- Evaluate thoroughly for infection with ESR, CRP, white cells, cultures, and manual cell counts.
