Task: Answer Verification
Input (English): Question: Do primary and Revision Posterior Lumbar Fusion Have Similar Short-Term Complication Rates?
Answer: This study suggests that revision posterior lumbar fusion does not carry significantly increased risk of complications or readmission compared with a primary posterior lumbar fusion. Patients undergoing revision surgery were more likely to receive a blood transfusion. This information suggests that general health risk stratification for revision procedures can be similar to that considered for primary cases.
Output (English): yes
