Muscle Biopsy; Processing and Evaluation

Muscle biopsy is a diagnostic procedure to recognize myopathological lesions in skeletal muscle. It may be an open surgical procedure or performed by needle biopsy. The muscle biopsy ought to target a myopathologically affected muscle, chosen by clinical features and/or myoimaging. Preparative techniques entail histology, electron microscopy, enzyme histochemistry, and immunohistochemistry, but it is essential to leave additional tissue for possible subsequent biochemical and molecular investigations. The backbone of light microscopic, diagnostic studies is unfixed frozen muscle tissue with cross-sectioned muscle fibers. Correct archiving of biopsied muscle tissue for future diagnostic and …
