Richard Webber's Cobalt Toxicity Diagnosis
Richard's assumed Alzheimer's diagnosis is overturned when numbness, EMG findings, and a cobalt hip implant point to cobalt toxicity.
In Plain English
Richard's numbness changes the question: instead of accepting Alzheimer's disease, the team looks for nerve damage and a toxic source.
What Happened in the Episode
Andrew stops the nerve biopsy and points to Richard's cobalt replacement hip as the missing clue.
Clinical Concept
Cobalt toxicity from a hip implant
What ER Teams Would Evaluate
A real team would review implant records, neurologic findings, EMG results, blood cobalt and chromium levels, hip imaging, medication and exposure history, and whether revision surgery is appropriate.
Treatment and Management Overview
Episode-supported management includes EMG testing, blood testing for cobalt toxicity, stopping a nerve biopsy, implant removal, new hip replacement, and postoperative monitoring.
What TV Gets Right
The episode correctly treats new neurologic clues as a reason to revisit the diagnosis.
What TV Compresses
It compresses device-record review, metal ion test turnaround, imaging, informed consent, surgical planning, and postoperative recovery.
