Herein, we present a case with a burst fracture injury at the proximal Conus Medullaris (CM). Case Presentation: A 48-year-old Taiwanese male presenting with lower back pain and paraparesis was having difficulty standing independently after a traumatic fall. An Imaging survey showed an incomplete D burst fracture of the T12 vertebra. Posterior decompression surgery was subsequently performed. However, spasticity and back pain persisted for four months after surgical intervention. Follow-up imaging with single photon emission computed tomography (SPECT) and a whole body bone scan both showed an increased uptake in the T12 vertebra. Conclusion: The high-riding injury site for CMS is related to a more exclusive clinical representation of UMNS. Our case\u2019s persistent UMNS and scintigraphy findings during follow-up showcase the prolonged recovery period of a UMN injury. In conclusion, our study provides a different perspective on approaching follow-up for CM injuries, namely using scientigraphy techniques to confirm localization of persistent injury during the course of post-operative rehabilitation. Furthermore, we also offered a new technique for analyzing the location of lumbosacral injuries, and that is to measure the location of the injury relative to the tip of the CM. This, along with clinical neurological examination, assesses the extent to which the UMN is involved in patients with CMS, and is possibly a notable predictive tool for clinicians for the regeneration time frame and functional outcome of patients with lumbosacral injuries in the future.<\/jats:p>","DOI":"10.3390\/tomography9060156","type":"journal-article","created":{"date-parts":[[2023,10,27]],"date-time":"2023-10-27T11:18:52Z","timestamp":1698405532000},"page":"1999-2005","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["High-Riding Conus Medullaris Syndrome: A Case Report and Literature Review\u2014Its Comparison with Cauda Equina Syndrome"],"prefix":"10.3390","volume":"9","author":[{"given":"Ya-Lin","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Medical Education, Kaohsiung Veterans General Hospital, Kaohsiung 813414, Taiwan"},{"name":"School of Medicine, National Defense Medical Center, Tri-Service General Hospital, Taipei 114201, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4005-2094","authenticated-orcid":false,"given":"Shin-Tsu","family":"Chang","sequence":"additional","affiliation":[{"name":"School of Medicine, National Defense Medical Center, Tri-Service General Hospital, Taipei 114201, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, Kaohsiung Veterans General Hospital, Kaohsiung 813414, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"886","DOI":"10.1038\/sc.2017.54","article-title":"Definitions of traumatic conus medullaris and cauda equina syndrome: A systematic literature review","volume":"55","author":"Brouwers","year":"2017","journal-title":"Spinal Cord"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"e204","DOI":"10.1016\/j.apmr.2022.08.041","article-title":"The ambulatory outcomes of traumatic cauda equina syndrome and conus medullaris syndrome: A systematic review","volume":"103","author":"Chen","year":"2022","journal-title":"Arch.
