Research Synopsis

Dr. Soneji’s research has focused on ultrasound guidance techniques as an imaging modality for chronic pain interventions. Research initiatives and collaboration in this area have led to three peer-reviewed publications since his appointment in September of 2013, including a first author publication comparing ultrasound and x-ray guidance for sacroiliac joint injection. He most recently submitted a first author publication on ultrasound guidance for ankle interventions for chronic pain, which has been accepted for publication in Regional Anesthesia and Pain Management. This academic work has contributed to the growing body of literature on the role for ultrasound-guided interventions for chronic pain management. In addition, Dr. Soneji has collaborated with colleagues to study the issue of prolonged opioid use after major surgery. Their publication in the British Medical Journal helped provide insights regarding relatively low risk of prolonged opioid use after major surgery, insights that have been very important in the context of growing opioid use in society. Dr. Soneji and his colleagues are currently working on a subsequent stage of the study to help patients and physicians better understand rates and risk factors for prolonged opioid use after major surgery.
