PubMed^® Literature Review

Corrective osteotomy of the radius following fracture nonunion is a complex procedure that requires meticulous preoperative planning and precise intraoperative execution to restore normal anatomy and function [1-3]. The fundamental themes emerging from the literature emphasize the importance of detailed imaging analysis, three-dimensional (3D) simulation, patient-specific instrumentation, and advanced intraoperative visualization techniques.

The use of 3D imaging has revolutionized preoperative planning by allowing surgeons to appreciate deformities in all planes accurately. This technology facilitates the simulation of corrective procedures using mirrored images from the unaffected limb as templates [3]. Bauer et al. demonstrated that patient-specific surgical guides manufactured based on such simulations could lead to successful outcomes in children with forearm deformities [3]. Their study showed significant improvements in forearm rotation arc postoperatively without any loss of range motion when using these custom guides.

Yoshii et al.'s research further supports technological advancements by introducing an image fusion system combining 3D preoperative plans with real-time fluoroscopy during surgery [1]. Their findings suggest improved reproducibility when utilizing this image fusion system compared to traditional methods without it. Specifically, they reported smaller discrepancies between planned corrections versus actual post-operative results at specific anatomical reference points when using their system.

Wada et al.’s article provides a step-by-step technique for simultaneous radial closing-wedge and ulnar shortening osteotomies aimed at treating malunions specifically involving distal radial fractures [2]. They underscored critical steps such as restoring volar tilt angle within a specified range through radial osteotomy while correcting ulnar variance via ulnar shortening. Although they did not utilize 3D printing or image fusion technologies directly mentioned in other studies reviewed here, their emphasis was on achieving precise correction through careful operative technique supported by fluoroscopic evaluation.

Collectively, these articles highlight several key considerations for planning corrective osteotomies:

1. Detailed Imaging: Preoperative imaging must be comprehensive enough to allow full appreciation of deformity. 2. Simulated Planning: Utilizing computer software aids in simulating potential corrections based on mirror images or other reconstruction algorithms. 3. Patient-Specific Instrumentation: Custom guides can ensure accurate translation from plan to surgical execution. 4. Intraoperative Visualization: Advanced systems like image fusion can enhance accuracy during surgery by superimposing virtual plans onto live fluoroscopic images. 5. Surgical Technique: Even with technological aids, meticulous surgical technique remains crucial; this includes respecting anatomical landmarks, managing soft tissues carefully, ensuring stable fixation post-osteotomy.

In conclusion, while each study contributes valuable insights into different aspects or techniques involved in corrective osteotomy for radius fracture nonunion—the integration of advanced imaging modalities coupled with patient-specific instruments appears essential for optimizing outcomes—this synthesis underscores an evolving paradigm shift towards precision medicine even within orthopedic surgery where individualized treatment strategies informed by high-fidelity simulations may become standard practice.
