AI Article Synopsis
- The extensor pollicis longus (EPL) is a crucial muscle for thumb extension, and its rupture can significantly impair hand function in patients.
- This systematic review investigates various traumatic causes of EPL rupture, beyond the commonly known issue of distal radius fractures, to enhance understanding of this rare injury.
- The study analyzed 37 articles, revealing that while distal radius fractures are the primary cause, other factors like lacerations and blunt trauma also contribute to EPL rupture cases.
Article 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 it 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 EPL 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 EPL 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.

Background: Rupture of extensor pollicis longus tendon (EPL) is a known complication following a distal radius fracture (DRF). Although the precise mechanisms behind these ruptures remain unclear, vascular impairment is thought to play a significant role. Additionally, the impact of an EPL rupture on microstructure of the tendon and muscle is not well understood, but such information could be important in guiding treatment strategies.

Spontaneous rupture of the extensor pollicis longus (EPL) tendon has been reported to be uncommon. Several possible causes and precipitating factors have been reported for this rupture, including prior surgery to the distal radius. We report the case of an 18-year-old male professional athlete who presented with an inability to extend their left thumb.

Article Synopsis
- The study aimed to assess the course and positioning of the extensor pollicis longus (EPL) tendon in relation to nearby structures and its clinical importance in different functional positions.
- Twenty human cadaver arms were examined to measure the EPL tendon’s movement, its wrapping angle around Lister’s tubercle, and its path near other tendons.
- The results indicated significant tendon mobility, highlighting the importance of understanding its anatomy for better diagnosis and surgical treatment of wrist injuries.

Introduction: Due to its ability to provide stable fixation and permit early mobilization, volar plating has become the recommended technique for the surgical stabilization of distal radius fractures. The extensor pollicis longus (EPL) tendon may be injured or ruptured as a result of undetected screw penetration or drill plunging. During surgery, it is critical to detect any potential screw penetration so that it can be corrected.
