Summary
The PRECICE nail offers accurate and precise bone lengthening for limb length discrepancies, with minimal effects on joint motion. Further long-term studies are needed to confirm its efficacy and compare it with other devices.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Regenerative medicine
Background:
- Internal bone lengthening devices have historically faced challenges with precision, leading to complications.
- The magnet-operated PRECICE nail is a recent FDA-approved device, but its clinical effectiveness requires evaluation.
Purpose of the Study:
- To assess the accuracy and precision of distraction achieved with the PRECICE nail.
- To evaluate the nail's impact on bone alignment and adjacent joint range of motion (ROM).
- To determine the frequency of implant-related and non-implant-related complications.
Main Methods:
- Retrospective review of 24 patients undergoing femoral/tibial lengthening with the PRECICE nail.
- Analysis of medical and radiographic records from August 2012 to July 2013.
- Evaluation of distraction accuracy, bone alignment, joint ROM, and complications at postoperative visits.
Main Results:
- Mean total lengthening was 35 mm, with 96% accuracy and 86% precision.
- Minimal adverse effects on bone alignment and adjacent joint ROM were observed.
- One implant failure (4%) and six non-implant-related complications (24%) were reported.
Conclusions:
- The PRECICE internal lengthening nail is a viable option for accurate and precise limb lengthening.
- Further randomized, larger-sample, long-term studies are necessary to confirm clinical efficacy and compare with alternative devices.
