Summary
Three-dimensional (3D)-printed prostheses effectively reconstructed cervical lateral masses in 7 patients, maintaining stability without complications. This innovative approach shows promise for cervical spine reconstruction and fusion.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Spinal Fusion
Background:
- Cervical lateral mass reconstruction is crucial for spinal stability.
- Traditional methods may face limitations in complex cases.
Purpose of the Study:
- To evaluate the efficacy of 3D-printed prostheses for cervical lateral mass reconstruction.
- To assess the maintenance of cervical stability and patient outcomes.
Main Methods:
- Retrospective analysis of 7 patients undergoing cervical lateral mass reconstruction.
- Utilized 3D-printed prostheses for axial and subaxial reconstruction.
- Included both unilateral and bilateral reconstructions.
Main Results:
- All 7 patients achieved stable internal fixation postoperatively.
- No implant-related complications (loosening, displacement, compression) were reported.
- Successful fusion was achieved in all cases.
Conclusions:
- 3D-printed prostheses are a viable option for cervical lateral mass reconstruction.
- Restoration of lateral mass structure aids in physiological load transfer.
- The technique promotes fusion and avoids complications, enhancing cervical stability.
