Quadratus Lumborum Type 2 as Chronic Hip Pain Treatment

Study Overview
=================
Brief Summary
-----------------
The main objective of the study is to assess whether the performance of type 2 quadratus lumborum block produces an improvement in the quality of life of the patient with osteoarthritis of the hip.

Detailed Description
-----------------
The lumbar square block is an interfascial block of the posterior wall of the abdomen, initially described for the management of postoperative pain in abdominal surgery due to its suggested effect on the T7-11 roots. The analgesic efficacy of type 1 lumbar square block (QL1) in hip surgery was subsequently published. Regarding chronic pain, QL2 has been successfully performed in posttherniorrhaphy pain or pancreatic cancer. This quadratus lumborum type 2 is performed in the patients with hip joint based on the innervation of the hip and taking the role of thoraco-lumbar fascia in the analgesia of these patients as a reference. The good results obtained in the first 5 patients have led us to evaluate whether this blockade can indeed be an analgesic alternative in patients with coxarthrosis.
