Overview
Open injuries to the common digital nerve are typically caused by penetrating trauma 1. These injuries are often not isolated and may involve other structures, such as flexor tendons and neurovascular bundles 1.Diagnosis
Thorough clinical assessment is required for suspected injuries 1.
Detailed understanding of digital nerve anatomy and spatial relationships is essential 1.Management
Principles of repair include preserving nerve blood supply and ensuring a smooth repair interface 1.
Adequate exposure of the zone of injury using full-thickness skin flaps is essential 1.
Preservation of neurovascular structures is critical 1.Key Recommendations
Suspected flexor tendon injuries require a thorough clinical assessment and often are not isolated injuries 1. (Evidence: Expert opinion)
Adequate exposure of the zone of injury using full-thickness skin flaps and preservation of neurovascular structures is essential 1. (Evidence: Expert opinion)
Principles of repair include a strong suture construct, minimising gap formation between ends, preserving blood supply, and providing a smooth repair interface 1. (Evidence: Expert opinion)References
