Patients with this disorder may have recurrent hip surgeries and may need physical therapy in the following years. The aim of this case report is to raise awareness among doctors, that hip denervation can be used in pain management for the rehabilitation of patients with congenital hip dislocation.Methods After repeated hip surgeries, limitation of hip joint mobility developed in a 27-year-old female patient with congenital hip dislocation (figure 1). Due to her pain, she could not receive restricted treatment and could not continue physical therapy. Repetitive Pericapsular nerve group (PENG) blocks (bupivacaine%0.125 + methylprednisolone 40mg mixture) were applied to the patient under USG guidance, and the pain was relieved for a limited time. A perminent pain relief theraphy was sought. Sensory branches of the obturator and femoral nerve pulsed radiofrequency (PRF) (for 6 minutes at 42 degrees) which is called hip denervation, were applied to the patient for long-term pain management under fluoroscopy guidance.Results After the intervention, the patient‘s pain decreased and she was able to continue physical therapy and exercise. At the 6th month follow-up, the patient‘s pain was under control. No procedural adverse event was noted.Abstract #36470 Figure 1 Patient with congenital hip dislocationConclusions The use of this hip denervation technique for hip pain control is evolving. In our experience, percutaneous radiofrequency lesioning of the sensory branches of the nerves innervating the hip joint can be an option for patients with intractable hip joint pain.
