Minimally Invasive Spine Fusion (MISF) is a surgical procedure that uses smaller incisions and specialized instruments to fuse vertebrae and stabilize the spine. It aims to reduce tissue damage, pain, and recovery time compared to traditional open spine fusion.
How it works:
• In a traditional open fusion, the surgeon makes a large incision and retracts muscles to access the spine.
• MISF, on the other hand, uses smaller incisions, often just a few small punctures, and specialized instruments to reach the spine.
• The surgeon may use tubes with endoscopes or other instruments to see and work on the spine within a smaller space.
• Bone grafts or other materials are used to promote fusion, and metal hardware may be used to stabilize the vertebrae.
Conditions treated:
MISF can be used to treat various spine conditions, including:
• Spinal instability (including spondylolisthesis)
• Vertebral compression fractures
Advantages of MISF:
• Smaller incisions: Reduced tissue damage and pain.
• Shorter recovery: Patients often return to activities faster.
• Less blood loss: Reduced risk of infection.
• Less muscle damage: Less pain and quicker recovery.
• Shorter hospital stays: Some cases allow for outpatient surgery.
Considerations:
• Steeper learning curve: MISF techniques require specialized training.
• Technical challenges: Some anterior MISF procedures may be more difficult.
• Risk of complications: While less common than in open surgery, risks like infection, nerve damage, and non-union (failure to fuse) still exist.
Recovery:
• Recovery time is typically shorter than with open spine fusion, averaging 6-12 weeks.
• Patients may experience some stiffness and soreness after surgery.
• It's important to follow the surgeon's instructions and physical therapy recommendations for optimal recovery
