Methods: Fifteen patients who underwent injection of a transposed ulnar nerve between 2014\u20132024 were identified. Sonographic appearances of the injected segment were scored using a Likert grading system for abnormality, and the cross-sectional area (mm2) was measured. Follow-up with respect to clinical response, need for subsequent therapeutic injection or decompressive surgery was recorded. Results: The grade of abnormality was mild (n = 4), moderate (n = 5), and severe (n = 3), with the remainder morphologically normal (n = 3). Inter-rater agreement was 0.91 (95% CI 0.80\u20131.00) with p &lt;0.001. Crosssectional area ranged from 8\u201318 mm2. Fourteen of fifteen patients (93%) experienced relief at the time of injection, decreasing to 12\/15 (80%) at short-term follow-up &lt;3 months, and further falling to 7\/15 (47%)\n&gt;3 months. Five patients (33%) underwent subsequent therapeutic injections, and three (20%) proceeded to revision surgery. There were no significant differences in grade between patients who experienced relief at any of the three time-points (p &gt;0.05), nor differences in deformity or cross-sectional area between those who underwent subsequent injection (p &gt;0.05) or surgery (p &gt;0.05). Conclusion: Ultrasound-guided injection is a viable option for refractory neuropathic symptoms, although relief was often temporary, and 20% eventually required revision surgery.<\/jats:p>","DOI":"10.15557\/jou.2026.0011","type":"journal-article","created":{"date-parts":[[2026,7,2]],"date-time":"2026-07-02T12:50:56Z","timestamp":1782996656000},"source":"Crossref","is-referenced-by-count":0,"title":["Ultrasound-guided therapeutic injection of the surgically transposed ulnar nerve at the elbow: sonographic appearances, technique and clinical follow-up"],"prefix":"10.15557","volume":"26","author":[{"given":"Christopher John","family":"Burke","sequence":"first","affiliation":[{"name":"Radiology, NYU Langone Orthopedic Hospital, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vinh","family":"Tran","sequence":"additional","affiliation":[{"name":"Radiology, NYU Langone Orthopedic Hospital, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allison","family":"Weinstock","sequence":"additional","affiliation":[{"name":"Radiology, University of Pittsburgh Medical Center, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dhruv","family":"Shankar","sequence":"additional","affiliation":[{"name":"Orthopedic Surgery and Sports Medicine, University of Washington School of Medicine, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald","family":"Adler","sequence":"additional","affiliation":[{"name":"Radiology, NYU Langone Orthopedic Hospital, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6250","published-online":{"date-parts":[[2026,6,30]]},"reference":[{"key":"ref0","doi-asserted-by":"crossref","unstructured":"Bartels RH, Menovsky T, Van Overbeeke JJ, Verhagen WI.
