Providing pain relief and helping with the diagnosis of the cause of pain are the main benefits of hip joint injections for arthritis, according to Spine-health. Doctors determine the source of pain based on the amount of pain relief the patient experiences during the injection procedure.
Doctors usually recommend hip joint injections to patients who have arthritis, mechanical stress or an injury and are experiencing hip, buttock, low back or leg pain, states Spine-health. During the procedure, a numb and completely painless hip joint possibly indicates that the hip joint is the origin of the pain. Doctors also inject time-release cortisone to relieve inflammation, thus providing lasting pain relief. Hip joint injections take about 30 minutes to an hour.
