Distal tibia fractures represent a notable occurrence in clinical practice, constituting approximately 10% of all tibia fractures and 1.5% of all adult fractures. In recent years, the incidence of distal tibia fractures has significantly increased. Recent biomechanical studies have highlighted retrograde distal tibia nail (DTN) as an innovative surgical alternative for managing distal tibia fractures, demonstrating its potential superiority over plating techniques. First, the distal curved configuration of the DTN aligns more harmoniously with the distal tibia morphology. Biomechanically, retrograde DTN exhibits superior resistance to rotation and axial stability compared to antegrade tibia intramedullary nails and plates. The successful achievement of fracture healing without distal tibia valgus deformity in all DTN patients underscores the commendable stability of this technique. Second, DTN simplifies fracture reduction and fixation, offering greater convenience with a high accuracy in its locking nail aiming device, thereby reducing the operation time and radiation exposure. Third, the limited length of the DTN ensures that the nail does not traverse the isthmus of the tibia shaft, resulting in reduced influence on the bone marrow cavity. This feature can reduce the risk of fat embolism. Finally, DTN employs the medial ankle as the entry point, effectively averting anterior knee pain. Postoperative AOFAS results confirmed its minimal impact on the ankle joint.
