However, no published clear guidelines are available about the access route for the surgical treatment of pyogenic spondylitis. The objective of this study was to compare clinical outcomes according to surgical treatment approach (anterior approach with or without posterior approach versus posterior only approach) of pyogenic spondylitis. Methods: This study included patients who underwent surgical treatment for pyogenic spondylitis. These patients were divided into two groups according to surgical treatment approach: anterior approach with\/without posterior approach (anterior group) and posterior-only approach (posterior group). Their baseline data, treatment failure, radiologic outcome, and ambulatory ability were compared. Results: Demographic data and clinical characteristics were similar (p &gt; 0.05) between the two groups. Baseline radiologic characteristics of infection, including infected spinal level, number of infected segments, presence of epidural abscess, and vertebral body collapse, were also comparable between the two groups. The number of unplanned surgeries was less in the anterior group than in the posterior group (p &lt; 0.05). Approach-related complications tended to occur more often in the anterior group, although the difference was not statistically significant (p = 0.067). There was no significant difference in radiologic outcome or final ambulation ability after surgery between the two groups (p &gt; 0.05). Conclusions: Anterior approach with or without posterior approach offers fewer treatment failure rates, particularly regarding revision surgeries, than a posterior-only approach. Thus, an anterior approach with or without a posterior approach should be used when planning surgical treatment for pyogenic spondylitis.<\/jats:p>","DOI":"10.3390\/jcm15103843","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T12:36:40Z","timestamp":1779107800000},"page":"3843","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Clinical Outcomes of Surgical Treatment for Pyogenic Spondylitis According to Surgical Approach"],"prefix":"10.3390","volume":"15","author":[{"given":"Sung-Woo","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital, Seoul 04401, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chi Young","family":"An","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital, Seoul 04401, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Lim","family":"Baek","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital, Seoul 04401, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min Jung","family":"Baek","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, CHA University College of Medicine, Seoul 06135, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8272-6723","authenticated-orcid":false,"given":"Jae Chul","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital, Seoul 04401, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8783-3122","authenticated-orcid":false,"given":"Hae-Dong","family":"Jang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital, Seoul 04401, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byung-Joon","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital, Seoul 04401, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"739","DOI":"10.31616\/asj.2020.0262","article-title":"Tuberculous and brucellar spondylodiscitis: Comparative analysis of clinical, laboratory, and radiological features","volume":"15","author":"Hammami","year":"2021","journal-title":"Asian Spine J."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"381","DOI":"10.31616\/asj.2020.0086","article-title":"Functional outcomes in spinal tuberculosis: A review of the literature","volume":"15","author":"Yong","year":"2021","journal-title":"Asian Spine J."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"e29366","DOI":"10.1097\/MD.0000000000029366","article-title":"Clinical differences between delayed and acute onset postoperative spinal infection","volume":"101","author":"Choi","year":"2022","journal-title":"Medicine"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"3065","DOI":"10.1038\/s41598-021-82695-2","article-title":"One-stage posterior debridement, autogenous spinous process bone graft and instrumentation for single segment lumbar pyogenic spondylitis","volume":"11","author":"Su","year":"2021","journal-title":"Sci.
