Aim. The arthroscopic anatomy of the hip can be divided into two compartments separated from the acetabular labrum: the central compartment (CC) and the peripheral compartment (PC). In the treatment of femoral-acetabular impingement (FAI) cam type, due to asphericity of the femoral head, the arthroscopy of the peripheral compartment has provided new therapeutic options. The following report presents the technique we adopted to perform a hip arthroscopy of the peripheral compartment, adopted portals and potential benefits obtainable in the treatment of femoral-acetabular conflict type CAM.
Methods. We have re-evaluated complications related to the first 20 cases of FAI CAM type operation who underwent arthroscopic surgery at the Orthopedics and Traumatology Department of San Luigi Gonzaga Hospital. The operations were performed in the supine position using the technique proposed by Dienst to access the peripheral compartment the coxo-femoral.
Results. From our experience the use of superior and anterolateral portals as described by Dienst has highlighted the possibility of entering into joint by limiting the possible risk of injury to the cartilage by arthroscope and labrum. The absence of traction also means less potential risk to avoid allowing soft tissue injuries and neurological complications.
Conclusion. The hip arthroscopy in the treatment of FAI CAM type, thanks to advances in technology and developing new and better equipment, is now a standardized technique, and validated by the results.
