Distal radius fracture minimally invasive 3D printing reduction instrument

Distal radius fracture is one of the most common fractures, accounting for 17-20% of fracture surgeries in the emergency department. Dorsal comminution of the distal radius cortext and articular surface fragmentation are indicators of instability. During open reduction and internal fixation surgery, our medical device manufactured through 3D printing assist in fracture reduction and open internal fixation, particularly for dorsal fragments of the distal radius cortex. The reduction clamp enables better restoration of the tilt, radial height, and congruity of the radiocarpal joint. The disposable material can be prepared in a high-temperature sterile manner without deformation, and it is nearly transparent under intraoperative X-ray imaging, allowing clear observation of fracture reduction. Combining open internal fixation with pelvic clamps and self-designed 3D printed tools provides advantages of counteracting forces, ease of use, and no need for an assistant. This helps minimize the incision size and achieve optimal reduction and fixation of distal radius fractures.
