Hip arthrosis is a frequent and difficult to manage disease. The generated pain supposes a great impact in the quality life of the patient. The goal of the treatment should be to reduce pain and to improve function. Based on the complex innervation of the hip, the minimally invasive thecniques have been increasing. In this context, we present the results obtained in four patients with a hip chronic pain due to arthrosis, to whom we performed a quadratus lumborum block type 2 (QL2) with levobupivacaine plus dexametasone as therapeutic option. The results have shown a significant decrease of the intensity of pain (NRS) for more than 6 months.
