RESUMO
INTRODUCTION: Pain and hemorrhage are common in midshaft femoral fractures. Traction splints (TSs) can reduce pain and control hemorrhage, but evidence of their effectiveness in femoral fractures is still lacking. Through a systematic review, we aimed to analyze and discuss the potential role of TSs in the prehospital and emergency department (ED) setting. METHODS: The Embase, CINAHL, Cochrane, and PubMed databases were searched up to January 2022. All studies on femoral fractures in the prehospital or ED setting that compared TSs with immobilization or no intervention were included. Articles not written in English, German, or Dutch were excluded. Two authors screened all articles, assessed their quality, and included them if both agreed on their inclusion. The risk of bias was assessed using the modified Methodological Index for Non-Randomized Studies (MINORS). The primary outcome measures were pain and hemorrhage control, while the secondary outcome measures were survivability, morbidity, and complications. RESULTS: A total of 1,248 articles matched the search strategy, 24 articles were assessed for eligibility based on their abstracts, resulting in 20 articles being included in the synthesis. Ten articles reviewed the effects of TSs on pain, while five reported that the use of a TS was appropriate. All five articles that reviewed blood loss found benefits from the use of a TS. One study found significantly fewer pulmonary complications in patients who were splinted earlier at the scene of injury (level III). No difference was found in complications or mortality between prehospital patients receiving a TS or no TS (level III). None of the studies noted that TSs were a necessity in the ED setting; however, some argued that a TS is a necessary and useful prehospital tool in rural or military areas. CONCLUSION: TS use is associated with a decreased necessity for blood transfusions and fewer pulmonary complications. No favorable effects were found in terms of pain relief. We recommend the use of TSs in situations where one is likely to encounter a femoral fracture as well as when the time to definitive treatment is long. Further well-designed studies are required to validate these recommendations.
