Among these, data from patients who underwent MR neurography were analyzed. Abnormal nerve findings were defined as the presence of increased signal intensity, enlargement, constriction, and\/or loss of the fascicular pattern on MR neurography. Patients with abnormal nerve findings were categorized into two groups based on the presence or absence of constriction, and the differences in demographics, clinical symptoms, and treatment outcomes were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of 27 patients (19 males; mean age 47\u2009years), abnormal nerve findings were observed in 23 (85%) patients, of whom 13 (48%) had constrictions. Three patients (11%) exhibited no nerve abnormalities, whereas one patient had a tumor (malignant peripheral nerve sheath tumor). Nerve constrictions were most frequently observed proximal to the elbow joint, with a median location of 21\u2009mm proximal to the joint (interquartile range [IQR], \u22122 to 77\u2009mm). The patients with constriction were significantly younger (32 vs. 63\u2009years,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) and exhibited a higher prevalence of left\u2010sided involvement (85% vs. 20%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The relatively high frequency of nerve constriction suggests that MR neurography may be valuable in guiding further management, including possible surgical intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>III.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/mus.70245","type":"journal-article","created":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T06:05:14Z","timestamp":1780985114000},"page":"404-410","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Magnetic Resonance Neurography in Spontaneous Radial Neuropathy: An Unexpectedly High Rate of Nerve Constriction"],"prefix":"10.1002","volume":"74","author":[{"given":"Jae Woo","family":"Shim","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong Hun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung Min","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Radiology, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyun Su","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8001-7782","authenticated-orcid":false,"given":"Jong Geol","family":"Do","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Do Kyung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Samsung Changwon Hospital, Sungkyunkwan University School of Medicine  Changwon South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min Jong","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,8]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"1647","article-title":"Radial Nerve Palsy Associated With Fractures of the Shaft of the Humerus: A Systematic Review","volume":"87","author":"Shao Y.
