Hip Arthroscopy in Adolescents Through an Extra-Capsular Approach.

Hip arthroscopic treatment for femoroacetabular impingement syndrome and labral tears is the gold standard in the adult and adolescent population, as we all know the most common surgical approach to the hip is entering the central compartment with fluoroscopy and with continuous distraction. A periportal capsulotomy in traction must be done to have visibility and instrument maneuverability. These maneuvers avoid scuffing the femoral head cartilage. In adolescents, extreme care must be taken in hip distraction, as the force used can cause iatrogenic neurovascular lesions, avascular necrosis, and lacerations of the genitals and foot/ankle. Experienced surgeons around the world have developed an extracapsular approach to the hip with smaller capsulotomies with a low complication rate. This approach to the hip has brought attention in the adolescent population because it is more secure and simple. Less force of distraction is needed because the capsulotomy is done first. This surgical technique allows observation of the cam morphology while entering to the hip without distraction. We describe an extracapsular approach as an option to treat femoral acetabular impingement syndrome and labral tears in the pediatric and adolescent population.
