Peri-articular Nerve Group Block Versus Fascia Iliaca Block on Postoperative Pain After Hip Arthroscopy
Peri-articular Nerve Group Block Versus Fascia Iliaca Block on Postoperative Pain After Hip Arthroscopy
The study aims to evaluate the efficacy of pericapsular nerve group block versus fascia
 iliaca block in reducing post operative pain within the first 24 hours following hip
 arthroscopy
In recent decades hip arthroscopy gained popularity and the number of procedures increase
 every year , due to the widening range of indications, as femoroacetabular impingement,
 labral tears, chondral injuries, loose bodies, osteonecrosis and septic arthritis Pain after
 hip arthroscopy due to several factors. divided in two regions. First the intra-articular
 where pain originates from the joint capsule (capsulotomy), a repaired labrum or bony
 resection. Outside the joint caused by traction, the portal tracts and extravasation of
 irrigation , soft tissue swelling.

 the hip joint found to be innervated from the femoral nerve for its anterior part, the
 obturator nerve for its antero-medial part, the sciatic nerve for its posterior part, and the
 nerve to the quadratus femoris muscle for its postero-medial par

 Pericapsular Nerve Group (PENG) Block aims to block the articular branches of the accessory
 obturator and femoral nerve Also, it could spread to block the obturator nerve and its
 articular branches the high articular branches from FN and AON are found between the anterior
 inferior iliac spine(AIIS) and the ilio pubic eminence (IPE), whereas the ON is located close
 to the inferomedial acetabulum.

 The fascia iliaca compartment is a virtual space anteriorly limited by the posterior surface
 of the fascia iliaca, posteriorly by the iliacus muscle and is cranially in continuation with
 the space between quadratus lumborum muscle and its fascia . Three important nerves for hip
 innervation are located in this space, the femoral nerve, obturator nerve and lateral femoral
 cutaneous nerve
