Title: Etiology of traumatic causes of extensor pollicis longus tendon rupture; systematic review

Abstract

Introduction: The Extensor pollicis longus (EPL) is a muscle that follows a complex anatomical course in the hand to allow for thumb extension. Almost all manual activities require the use of the EPL; therefore, when ruptured can be very disabling for patients. The etiologies behind traumatic EPL rupture were mostly attributed to distal radius fracture in the literature. However, EPL rupture remains uncommon, and other traumatic etiologies exist. Therefore, this systematic review aimed to provide a holistic view of the traumatic etiologies behind the EPL rupture and fill the global lack of knowledge regarding this rare injury. Materials and Methods: We searched among Cochrane Central Register of Controlled Trials (CENTRAL) Embase, Medline, and Cochrane Database of systematic review register databases via Ovid, with no restriction on the date, including studies containing data about the etiology of traumatic causes of extensor pollicis longus tendon rupture with available full text, and excluding non-English and animal studies. Results: A total of 37 articles with 371 cases constituted the basis of this review. We classified the etiology of the extensor pollicis longus rupture into three groups according to the affected anatomical structure that caused the EPL rupture (fracture-related, soft-tissue-related, and mallet thumb).
Conclusion: Distal radius fractures remain the most common cause of EPL rupture; however, other causes, such as lacerations, blunt trauma, and direct cuts to the EPL tendon, should be considered.

Biography

I am medical intern with a passion for volunteering and research. Throughout my medical education, I have been an active member of the university's volunteering community, dedicating countless hours to various causes and organizations. I have volunteered at local hospitals, clinics, and community centers, providing care and support to those in need especially during Covid-19 pandemic. In addition to volunteering, I have passion for research. I worked on several research projects, including different types of studies. I believe that access to healthcare is a fundamental human right and has worked to address healthcare disparities through volunteering and research. I am approaching graduation, and excited about the opportunities that lie ahead. I plan to continue volunteering and pursuing research opportunities while completing residency training
