摘要

Background

Ollier disease is an uncommon skeletal disorder with a significant malignancy risk, which complicates surgical treatment.

Case presentation

This case study showcases the surgical treatment with advanced imaging and innovative patient-specific (PS) cutting guides implemented for intercalary allograft reconstruction to remove the deformity in a 12-year-old male with Ollier disease. Wide excision was performed successfully, followed by complete bone fusion within five months. Functional recovery of the left arm was achieved by 30 months through active assistive motion exercises, with no postoperative complications observed.

Conclusion

This case highlights the utility of computer-aided techniques and patient-specific (PS) instruments in achieving precision during orthopaedic surgeries. These tools enable accurate bone resections that help attain the desired surgical margins while preserving function, particularly in anatomically complex scenarios.
