Thoracolumbar fracture dislocation (AO type C injury): A systematic review of surgical reduction techniques.

ABSTRACT: Spinal injuries constitute about 3% of all injury cases and most of these injuries affect the thoracolumbar region, but thoracolumbar fracture-dislocations are much rarer. Dislocations (AO Type C injuries) of the thoracic and lumbar vertebrae, with or without associated fractures, happen due to very high energy trauma involving simultaneous, multidirectional, distractive and compressive forces across various spinal elements, which results in translational and rotational instability of the spinal column. Various reduction maneuvers have been described for thoracolumbar fracture-dislocations in the literature aiming to provide standardization in surgery for this situation. The aim of this review article is to systematically review the literature till date and describe various reduction maneuvers which help to achieve adequate sagittal and coronal balance as well as vertebral alignment with minimal soft tissue trauma. We searched the PubMed, the Cochrane Library (the most recent issue), Scopus, Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, Web of Science, International Clinical Trials Registry Platform (WHO), ClinicalTrials.gov and Google Scholar databases, besides other sources and general internet search. The strategy used in the search was briefly(''thoracolumbar'' OR ''dorsolumbar'') AND "dislocation" in PubMed. Similar searches were made in the other databases.Reference lists of the relevant papers were also examined and any further relevant studies, which were also included in the review. The initial search revealed 332 papers in Pubmed, out of which 302 were human studies. A similar search on Scopus revealed 528 documents and on WoS revealed 289 papers. Searching the Cochrane library revealed 9 trials, which were already revealed in Pubmed search results. All the references were imported into Endnote and we had 632 references after excluding duplicates and 126 papers were left in endnote after manual title screening and duplicate removal. Finally, 70 relevant papers were selected for consideration based on inclusion criteria, after excluding unrelated papers manually. We have summarised the published literature on the surgical management of thoraco-lumbar fracture dislocations and described the reduction maneuvers used in detail.

Project description:BackgroundA wide variety of surgical techniques are used to perform vasectomy. The purpose of this systematic review was to assess if any surgical techniques to isolate or occlude the vas are associated with better outcomes in terms of occlusive and contraceptive effectiveness, and complications.MethodsWe searched MEDLINE (1966-June 2003), EMBASE (1980-June 2003), reference lists of retrieved articles, urology textbooks, and our own files looking for studies comparing two or more vasectomy surgical techniques and reporting on effectiveness and complications. From 2,058 titles or abstracts, two independent reviewers identified 224 as potentially relevant. Full reports of 219 articles were retrieved and final selection was made by the same two independent reviewers using the same criteria as for the initial selection. Discrepancies were resolved by involving a third reviewer. Data were extracted and methodological quality of selected studies was assessed by two independent reviewers. Studies were divided in broad categories (isolation, occlusion, and combined isolation and occlusion techniques) and sub-categories of specific surgical techniques performed. Qualitative analyses and syntheses were done.ResultsOf 31 comparative studies (37 articles), only four were randomized clinical trials, most studies were observational and retrospective. Overall methodological quality was low. From nine studies on vas isolation, there is good evidence that the no-scalpel vasectomy approach decreases the risk of surgical complications, namely hematoma/bleeding and infection, compared with incisional techniques. Five comparative studies including one high quality randomized clinical trial provided good evidence that fascial interposition (FI) increases the occlusive effectiveness of ligation and excision. Results of 11 comparative studies suggest that FI with cautery of the vas lumen provides the highest level of occlusive effectiveness, even when leaving the testicular end open. Otherwise, firm evidence to support any occlusion technique in terms of increased effectiveness or decreased risk of complications is lacking.ConclusionsCurrent evidence supports no-scalpel vasectomy as the safest surgical approach to isolate the vas when performing vasectomy. Adding FI increases effectiveness beyond ligation and excision alone. Occlusive effectiveness appears to be further improved by combining FI with cautery. Methodologically sound prospective controlled studies should be conducted to evaluate specific occlusion techniques further.
