The use of a T-plate for the correction of angular limb deformities has not been previously described in the literature. This technique permits accurate correction of the angular limb deformity and minimizes postoperative complications.
Objective The aim of this study was to compare radiographic outcomes of open reduction versus fluoroscopic-guided closed reduction (FGCR) of sacroiliac fracture-luxations stabilized with a lag screw, as well as peri- and postoperative complications.
Study Design Medical records (2010–2015) and radiographs of dogs and cats diagnosed with sacroiliac fracture-luxation that underwent open reduction without fluoroscopic guidance (n = 24) or FGCR (n = 17) were retrospectively reviewed to assess sacroiliac fracture-luxation reduction and lag screw placement, and lag screw loosening on follow-up radiographs (range, 1–8 weeks postoperatively) when available. Peri- and postoperative complications were also recorded.
Results Optimal screw depth to sacral body width ratio (>60%) was achieved in a significantly higher proportion of FGCR cases than openly reduced fracture-luxations. A significantly lower rate of lag screw loosening was found for FGCR cases. Few peri- and postoperative complications were noted across both groups. Four out of 17 FGCR cases requiring conversion to an open approach were excluded from data analysis; they had a longer duration from trauma to surgical repair than the median duration from trauma to surgical repair for cases successfully reduced in closed fashion.
Conclusion Fluoroscopic-guided closed reduction of sacroiliac fracture-luxations leads to consistently more optimal screw placement, as well as a lower incidence of lag screw loosening on follow-up radiographs. However, for cases with a longer duration from trauma to surgical repair, one should be prepared to convert to an open approach if a closed approach is not amenable to adequate reduction and lag screw placement.
Most dogs recovered well with surgical decompression. Increasing degree of deficits preoperatively is significantly correlated with longer recovery time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
