[Update on gluteus medius syndrome]

Back pain and/or gluteal region pain is a frequent complaint in primary care and often is difficult to determine their origin. When a patient consults us for this reason we tend to direct the focus to the study of bone and nerve structures, without considering that in a large number of cases the myofascial system is involved. In a study with 250 patients in order to determine the prevalence of tendinosis and tear of the gluteus medius or minimus muscles, was found by MRI that 14% of patients who went to the doctor for pain in the buttock, hip or groin had this type of injury in any of the muscles mentioned (1). In these cases a diagnosis and early treatment with injections is essential to prevent progression to persistent pain and decreased muscle function.
