Summary
This study demonstrates how 3D-printed guides and computer navigation precisely correct severe tibial deformities in osteogenesis imperfecta, enabling patients to walk unaided and reduce knee pain.
Area of Science:
- Orthopaedic Surgery
- Biomedical Engineering
- Medical Technology
Background:
- Osteogenesis imperfecta (OI) frequently causes severe musculoskeletal deformities, impacting mobility and quality of life.
- Corrective surgery for complex tibial deformities in OI patients presents significant challenges due to bone fragility and deformity severity.
Observation:
- A 44-year-old male patient with OI presented with debilitating valgus and procurvatum tibial deformities.
- Bi-level osteotomies utilizing 3-dimensional (3D)-printed patient-specific cutting guides were performed for deformity correction.
- Computer-navigated total knee arthroplasty was concurrently performed to achieve neutral mechanical alignment.
Findings:
- Postoperative X-rays confirmed successful correction of the tibial deformities and restoration of alignment.
- One year after surgery, the patient experienced significant knee pain relief and regained unaided ambulation.
Implications:
- 3D-printed guides and computer navigation offer high precision for complex orthopaedic procedures.
- These advanced technologies, when mastered by surgeons, enable personalized and effective management of challenging skeletal conditions.
- This approach holds promise for improving functional outcomes in patients with OI and similar complex deformities.
