Abstract

Disclosed herein are systems and methods for automatically forming a cylindrical metal implant used for orthopedic surgery. A control system receives patient musculoskeletal data sets, derives spinopelvic alignment parameters, simulates candidate realignment configurations with estimated musculoskeletal forces, and generates an implant fabrication instruction set. An implant fabrication device comprising a bending assembly, a feeding assembly, and a controller circuit uses a three-point bending mechanism to locally bend successive discrete segments of a metal rod and globally deform the rod according to a desired postoperative spinal alignment. The feeding system intermittently advances the rod into the bending mechanism and rotates to change the bending direction. Force and angle sensors provide feedback to accurately deform the rod to the specified angle taking into account elastic spring-back. An intraoperative verification module compares post-attachment alignment against the target and triggers re-bending if needed.
