    Area of Science:

    • Neurology
    • Surgical Pathology

    Background:

    • Muscle biopsy is essential for diagnosing neuromuscular disorders and investigating malignant hyperthermia.
    • Improper biopsy techniques can lead to inaccurate results and patient complications.

    Purpose of the Study:

    • To present a standardized, reproducible surgical technique for open vastus lateralis muscle biopsy.
    • To highlight the importance of technical details for optimal diagnostic yield and patient safety.

    Main Methods:

    • A specific surgical technique was applied to 93 open vastus lateralis muscle biopsies.
    • The procedure involved careful site selection, regional anesthesia, atraumatic dissection, and immediate sample processing.
    • A novel muscle biopsy clamp was utilized.

    Main Results:

    • The technique yielded high-quality samples for neuromuscular and malignant hyperthermia research.
    • 14 cases of malignant hyperthermia and various neuromuscular pathologies were identified.
    • No wound complications or patient disabilities were reported.

    Conclusions:

    • The described vastus lateralis muscle biopsy technique is safe, reproducible, and effective.
    • Meticulous attention to surgical detail is paramount for successful muscle biopsy procedures.
    • The vastus lateralis is recommended as the preferred biopsy site unless otherwise indicated.
