Our study aimed to determine the duration of pain relief from intraarticular hip corticosteroid injections and identify patient predictive factors on injection response. We also sought to determine the subsequent rate of hip surgery and whether severity of hip osteoarthritis or injection response correlated with the decision to undergo surgery. ⋯ Gender, age, BMI, duration of symptoms, and radiographic severity of disease do not predict injection response. Due to high surgical rates and poor response, intraarticular hip steroid injections may be less effective in the long term, and surgical management may be considered earlier.

To determine the effect of needle position and foraminal stenosis on contrast flow directionality during CT-guided transforaminal epidural steroid injections (TFESI). ⋯ Needle position is not significantly associated with contrast flow directionality during CT-guided TFESI, although there was a trend towards relatively decreased central flow with posterolateral positioning. Degree of foraminal stenosis and volume of injected contrast did not affect contrast flow directionality. There was no difference in immediate post-procedural pain scores with either direction of contrast flow.

The treatment of persistent cervical radicular pain (CRP) by CT-guided epidural steroid injections (CTESI) by a transforaminal anterolateral (TFA) approach is associated with rare but serious complications. Two recently described transforaminal posterolateral (TFP) and transfacet indirect (TFT) approaches may be safer options, but have not been extensively evaluated. We compared the efficacy of three CTESI approaches (TFA, TFP, and TFT) in the treatment of persistent CRP (>6 weeks). ⋯ The results of CTESI using the TFP or TFT approach are similar to those for TFA in the treatment of persistent CRP and could be a safer option.
