Epidemiology, classification, etiology, complications, and treatments of finger traumatic amputation: A literature review

Traumatic finger amputation is a significant medical and functional challenge with varied etiologies, ranging from workplace injuries to recreational accidents. While classification systems like Pulp, Nail, and Bone (PNB) have enhanced injury assessment, the management and outcomes of such injuries remain highly variable. This review aims to provide a comprehensive overview of the epidemiology, classification, etiology, complications, and management strategies for traumatic finger amputations. Relevant literature was identified through a systematic search of databases including PubMed, Scopus, and Google Scholar. Studies were selected based on their focus on traumatic finger amputation, including epidemiology, classification systems, mechanisms of injury, complications, and treatment approaches. The review reveals that traumatic finger amputations are most common among young males and are often associated with machinery and traffic accidents. The PNB classification system offers a detailed framework for evaluating injuries, complementing traditional systems. Complications such as arterial insufficiency, neuroma formation, and cold intolerance are frequently reported. Treatment options, primarily replantation and stump plasty, depend on the severity of tissue damage and patient-specific factors. Effective management of traumatic finger amputations requires a combination of surgical expertise and long-term rehabilitation to address functional and psychosocial challenges. Future research should focus on improving surgical techniques, advancing prosthetic designs, and standardizing treatment protocols to enhance patient outcomes.
