The rate of nonunion or pseudoarthrosis after spinal fusion surgery varies widely, but generally ranges from 5% to 35%. This variation depends on several factors including the type of surgery, patient-specific factors, and surgical technique.
It is known that Anterior approaches with anterior support were associated with a decreased rate of pseudarthrosis.
Factors Influencing Nonunion Rates:
• Surgical Levels:
Multilevel fusions (more than two levels) have a higher risk of nonunion compared to single-level fusions.
• Patient Factors:
Factors like smoking, obesity, diabetes, and age can increase the risk of nonunion.
• Surgical Technique:
Use of autograft fusion (using the patient’s own bone) can lower the risk compared to allograft (donor bone).
• Follow-up Duration:
Longer follow-up periods may reveal more cases of nonunion.
• Surgical Approach:
Different surgical approaches (e.g., anterior vs. posterior) may have varying rates of nonunion
Several risk factors for pseudarthrosis in long-segment spinal fusions for adult spine deformity (ASD), including fusion length (≥ 4 levels), osteotomy requirement, pelvic fixation, and combined surgical approaches. This study found that pseudarthrosis was not related to malalignment but with the surgical techniques employed. Anterior approaches with anterior support were associated with a decreased rate of pseudarthrosis.
• Factors affecting spinal fusion success rates: Several factors can influence the success rates of spinal fusion, including:
• Patient factors: Age, overall health, specific spinal condition, smoking, and long-term steroid use.
• Surgical factors: Surgical technique (e.g., minimally invasive vs. open), experience of the surgeon, use of specific bone graft types and implants, and length of the fusion.
• Post-operative adherence: Following rehabilitation guidelines and minimizing factors that hinder bone healing.
