Thyrotoxic Periodic Paralysis: A Spine Consultation.

Area of Science:

• Neurology
• Endocrinology
• Orthopaedics

Background:

• Orthopaedic spine surgeons frequently evaluate patients with acute-onset extremity weakness.
• It is crucial to consider non-spinal pathologies that can present with similar symptoms.

Observation:

• A 32-year-old man presented with rapid lower extremity weakness, tachycardia, and chest pain.
• Initial investigations focused on spinal pathology (CT, MRI), but were complicated by the patient's unstable condition.
• Metabolic panel revealed hypokalemia, prompting further investigation.

Findings:

• The patient was diagnosed with thyrotoxic periodic paralysis.
• Correction of hypokalemia led to rapid resolution of weakness.
• Spinal pathology was ruled out.

Implications:

• This case underscores the importance of a comprehensive differential diagnosis for acute extremity weakness.
• Awareness of non-orthopaedic conditions like thyrotoxic periodic paralysis is essential for spine surgeons.
• Prompt recognition and management of metabolic derangements can prevent unnecessary invasive procedures.
