Specimen Requirements

  1. Submit three separate muscle segments.
  2. The biopsy site should be one that is clinically affected, but not severely atrophic or previously needled for electromyography. Avoid fascia and fat.
  3. Select muscle bundles approximately 3 cm long x 0.5 cm in diameter.
  4. Do not infiltrate muscle with local anesthetic. Avoid trauma or stretching during excision.
  5. Tie a suture around one end of the muscle bundles to be removed using a small round curved needle. Tie a second suture at the other end of a 3 cm long and 0.5 cm in diameter bundle, cut across the bundle just beyond the suture.  Continue retracting, undercutting the strip of muscle.  Cut across the muscle attachment leaving both sutures attached to the specimen.
  6. Attach the muscle bundle to muscle biopsy clamps.
  7. Cover the biopsy with a saline moistened telfa. Do not immerse in saline solution.  Submit specimen on wet ice immediately.
