Observational Study
Predictors of the analgesic efficacy of CT-guided percutaneous pulsed radiofrequency treatment of Gasserian ganglion in patients with idiopathic trigeminal neuralgia.
Although pulsed radiofrequency (PRF) has few postoperative adverse reactions, its analgesic efficacy for trigeminal neuralgia (TN) is not always guaranteed. The response rate of PRF targeting the Gasserian ganglion for patients with TN varies. This study aims to identify the predictors of the analgesic efficacy of CT-guided percutaneous PRF in patients with idiopathic TN. ⋯ For patients who previously had positive responses to peripheral branch nerve block of the trigeminal nerve, PRF is likely to have better efficacy.

Adhesive capsulitis and disorders of the intra-articular portion of the long head of the biceps brachii tendon are common causes of shoulder pain. Sonographic findings, coupled with clinical evaluation and medical history, are paramount for prompt diagnosis. Herewith, either to precisely confirm the pain generator(s) or to appropriately treat relevant cases, ultrasound-guided interventions are often required in daily clinical practice. Targeting the anatomical structures involved in the aforementioned pathological conditions, we briefly describe some technical tips and tricks as regards ultrasound-guided hydrodilatation of the shoulder capsule at the rotator interval.

Total knee arthroplasty is a common and successful treatment modality for knee arthritis that is refractory to conservative management strategies. Over 600,000 arthroplasties are performed per year in the United States, and this number is expected to increase in the coming years. Unfortunately, 8% to 34% of patients experience chronic pain after having a total knee arthroplasty. ⋯ In this article, we outline the work-up of a painful total knee arthroplasty. Then we provide a thorough review of interventional pain management strategies and highlight the pertinent literature. Lastly, we hypothesize future developments in the field that may provide better outcomes for patients suffering from painful total knee arthroplasty.
