Stereolithography in spine pathology: a 2-case report

Area of Science:

• Medical Imaging
• Biomedical Engineering
• Orthopedic Surgery

Background:

• Stereolithography enables the creation of solid plastic anatomical replicas from medical imaging data (CT and MRI).
• These 3D models serve as valuable adjuncts in diagnosing and planning treatments for various spinal pathologies.

Observation:

• A 62-year-old male with degenerative cervical disease utilized a 3D spine replica for pre-surgical planning and patient education, improving his understanding and acceptance of necessary surgery.
• A 27-year-old female with chronic pain and anxiety, experiencing distress over a perceived failed surgery, found resolution after visualizing her repaired spine via a 3D model, leading to reduced anxiety and pain.

Findings:

• 3D spine replicas facilitate detailed study of pathological features and simulation of surgical approaches, such as osteophyte removal.
• Patient engagement with physical anatomical models enhances comprehension of their condition and the rationale behind surgical interventions.
• Visual and tactile interaction with 3D models can alleviate patient anxiety and misconceptions regarding treatment outcomes.

Implications:

• 3D printed anatomical models are effective tools for enhancing surgical planning, simulation, and patient education in spine care.
• These replicas can improve patient adherence and satisfaction by fostering a clearer understanding of complex medical information.
• The use of 3D models represents a significant advancement in personalized medicine, bridging the gap between complex imaging data and patient comprehension.
