Introduction: The extra-articular hip impingement involves a group of recently recognized lesions, commonly underdiagnosed and poorly understood by many orthopedic specialists. However, these lesions are capable of leading to pain and important functional decline in the affected patients. The correct diagnosis of these conditions is primal. It involves the need for an adequate knowledge of its pathogenesis and clinical evaluation through specific physical examination maneuvers, as well as correct interpretation of the imaging exams. Objective: To update medical professionals, physiotherapists, physical educators or any others who work in direct contact with the affected patients. Material and methods: A review of the literature was conducted on the PubMed and Birene /Lilacs databases on regard of anatomy, pathogenesis, clinical findings, imaging and treatment of the main causes of extra-articular hip impingement. Results: The most cited extra-articular impingement syndromes in the literature are the ischiofemoral, subspinal, trochanteric and iliopsoas impingements. These syndromes are dynamic conditions and the diagnosis must be done observing the presence of anatomical abnormalities, positive clinical examination and confirmation by imaging exams or intraoperative finding. Because they are lesions with a low prevalence reported, there is little evidence regarding these conditions and more studies are needed. Conclusion: Knowledge of extra-articular hip impingement syndromes is essential in the evaluation of patients with hip pain and should be part of the differential diagnosis.
