IntroductionAnkle fractures represent a significant portion of orthopedic injuries, with fracture dislocations tending to have worse outcomes. Logsplitter fractures represent a subset of fracture dislocations in which the talus is axially wedged in the tibiofibular joint. We aim to comprehensively investigate and report on the complications and functional outcomes associated with ankle fracture-dislocations.Materials And MethodsFollowing PRISMA guidelines, a medical librarian conducted a literature search in Embase, Ovid Medline, Scopus, Cochrane Central Register of Controlled Trials, and The Cochrane Database of Systematic Reviews. Studies examining ankle fracture-dislocations and reporting on functional or employment outcomes were included. Excluded were non-English studies, abstracts, conference proceedings, letters, perspective pieces, reviews, editorials, and case reports or series with fewer than five patients. Data on functional outcomes were extracted and reported using descriptive statistics. A comparative analysis of AOFAS scores between Logsplitter and ankle fracture-dislocations was conducted using pooled means and independent t-tests.ResultsA total of 21 studies involving 810 cases of ankle fracture-dislocations were included. The pooled mean AOFAS score across 13 studies was 81.5, indicating "good" outcomes, while Logsplitter injuries had a significantly lower mean score of 75.8 compared to 82.9 for other ankle fracture-dislocations (p = 0.016). Complications included wound infection (7.3%), posttraumatic osteoarthritis (29.2%), nonunion/malunion (12.6%), and malunion. No studies reported on employment outcomes.ConclusionsAnkle fracture-dislocations are high-energy injuries that affect a younger population compared to non-dislocated ankle fractures. Their functional outcomes resemble those of pilon fractures more than common ankle fractures. Logsplitter injuries are a subset of fracture dislocations that occur in even younger patients, with worse functional outcomes. This information can guide perioperative discussion and expectations for functional recovery. Additional studies are needed to evaluate the impact of these injuries on return to employment.© 2024.
