This PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-compliant case-based systematic review and meta-analysis aimed to comprehensively explore TPAD, covering clinical presentation, diagnosis, treatment, and clinical and radiological outcomes. Following the presentation of a case of TPAD without an associated fracture, we conducted a systematic search of electronic databases, including Scopus, PubMed, and Web of Science, from inception through October 2023, without language restrictions. Cases involving dislocations due to congenital anomalies or inflammatory processes were excluded. The search yielded 31 eligible cases of TPAD without an associated fracture. The majority (81%) of the cases were males, with traffic accidents being the leading cause (87%). Notably, 52% of the cases presented without any neurological deficits. Regarding treatment approaches, 23% of the cases were managed through closed reduction alone, 32% required fusion following closed reduction, and 45% underwent open reduction and fusion. A time delay exceeding 7.5 days was associated with a significantly higher risk of closed reduction failure (odds ratio, 56.463; p =0.011). This review identified key management strategies for TRAD without fracture, informed by the available evidence. Optimal management entails prompt closed reduction under C-arm while monitoring neurological status once hemodynamic stability is achieved. Surgical fusion is indicated for cases with magnetic resonance imaging-confirmed transverse ligament rupture or residual instability. If closed reduction fails, open reduction and fusion should be carried out. Posterior C1-C2 screws fixation is the preferred fusion technique, providing high levels of safety and biomechanical stability.</p>","PeriodicalId":8555,"journal":{"name":"Asian Spine Journal","volume":" ","pages":"889-902"},"PeriodicalIF":2.3,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11711164/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142799307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Postoperatively, the mean thoracic kyphosis was 13.84°±2.10° and 21.02°±1.68° in T and TP groups (p=0.044). Transient signal-loss intraoperatively was noted in two patients, one in each group. No episodes of postoperative neurological deficits were reported. No incidences of pseudarthrosis/implant-related complications were reported at the end of 2 years in either group.</p><p><strong>Conclusions: </strong>IOT and PO complement one another and can be safely combined without an attributable risk of neurological injury.</p>","PeriodicalId":8555,"journal":{"name":"Asian Spine Journal","volume":"18 6","pages":"794-802"},"PeriodicalIF":2.3,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11711172/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142942949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
