Muscle biopsy is an important test in the evaluation of individuals with suspected myopathy, including those with suspected idiopathic inflammatory myopathy (IIM). Various approaches, including open surgical biopsy, needle biopsy and conchotome forceps, have been reported. However the real-world utilisation of these approaches remains unclear. There are no established guidelines for the use of muscle biopsy, or selection of biopsy technique, in investigating IIM and international practices are not well-documented. This study describes current approaches to muscle biopsy amongst clinicians with expertise in IIM.
