Finger Injury Related to Climbing: Anatomy, Function, Mechanism of Injury, Diagnosis, Treatment

Abstract

Introduction Rock climbing has surged in popularity over the past few decades, attracting a diverse range of participants from recreational enthusiasts to professional athletes. While climbing offers numerous physical and mental benefits, it also presents significant injury risks. Rock climbing is a sport that imposes extreme stress on the fingers, particularly on the flexor pulley system. Injuries to these structures can severely impact a climber's ability to perform and progress in the sport. Understanding the anatomy, injury mechanisms, and treatment modalities is essential for effective management and prevention. Aim of the study The purpose of this narrative review is to comprehensively describe information on the anatomy, function, mechanism of injury, diagnosis, and treatment modalities of the finger flexor pulley system (FFPS). Materials and methods The methodology for the literature search involved using the keyword "pulley" and adding terms such as "treatment", "mechanism", "function", "anatomy", "diagnosis", and "symptoms". The search terms were entered into the PubMed and Google Scholar databases. The review works and clinical trials were taken into account. Conclusion Finger flexor pulley system (FFPS) strain is a common overuse injury in climbers, often caused by the crimp grip used in rock climbing. Pulleys A2 and A4 are particularly vulnerable. Diagnosis involves physical examination and imaging tests, such as ultrasonography and, if necessary, magnetic resonance imaging. Grade I to III injuries are typically treated conservatively, while surgical treatment may be necessary for grade IVb injuries. Using a splint or H-taping the fingers after an injury can help prevent further damage and provide support for the affected pulleys.
