Technical methods involving four guide pins by orthopedic robot-assisted PFNA surgery.(a, b), Planning the placement of the 1st guide pin (White) used to temporarily fix the fracture ends, planning the placement of the 2nd guide pin (blue) used to fix the lesser trochanter bone block, planning the placement of the 3rd guide pin (pink) used to guide the spiral blade, and planning the placement of the 4th guide pin (red) used to guide the main pin position. (c, d), With the assistance of the robot mechanical arm, these guide pins were placed under the guidance of anteroposterior and lateral fluoroscopy of the hip joint as needed. (e, f), Finally, under the guidance, PFNA was implanted and the results were verified by fluoroscopy.
