What flexor tendon zone is noted for having the worst prognosis when injured?

• A. Zone 1
• B. Zone 3
• C. Zone 2
• D. Zone 4

Answer: (C)

The flexor tendon zone noted for having the worst prognosis when injured is indeed Zone 2, commonly referred to as the "no man's land." This area encompasses the region between the A1 and A4 pulleys in the finger, where the flexor tendons are at a greater risk for complications if injured. The reason this zone has a poor prognosis is due to several factors related to the anatomy and healing potential within this area. In Zone 2, the tendons are surrounded by a dense, fibrous sheath, which can complicate surgical repair and healing. This zone has less vascular supply compared to other areas, leading to a higher risk of adhesions and decreased mobility post-repair. Moreover, injuries in this region often result in significant functional impairment, given the complexities of tendon gliding and the need for precise alignment during surgical intervention. Furthermore, the challenging nature of performing tendon repairs in this zone, along with the associated complications such as scarring, make rehabilitation more difficult. Clinicians often find that patients with Zone 2 injuries face longer recovery times and a higher likelihood of persistent dysfunction, which further emphasizes the poor prognosis associated with injuries in this particular area. Understanding the anatomical and functional implications of a Zone 2 injury is crucial
