Abstract
This study was conducted in order to evaluate the cost-effectiveness of percutaneous automated lumbar nucleotomy in comparison with traditional macro-procedure discectomy in the treatment of herniated discs.
Sixty-eight patients undergoing surgical procedures and 90 treated with nucleotomy were consecutively included. Both cohorts were assessed pre-operatively and at regular intervals for one year or more after treatment by independent observers, using a clinical overall scoring system (COS) with 0 being the best attainable result and 1000 the poorest conceivable status of the patients.
There were better clinical results after surgery with 78% successes after one year compared to 62% after nucleotomy. By including subsequent operations and re-operations after failure to respond to the primary treatment, the success rates rose to 79% and 77%, respectively.
The cost of surgical treatment was calculated to USD 6.119 per patient and the cost of a nucleotomy procedure was USD 1.252. Owing to an almost five times higher price of surgery than nucleotomy, the latter turned out to be 2.7 to 3.9 times more cost-effective, depending on whether secondary treatment was included or not. Due to the minimal difference in final outcome between the groups, however, the marginal cost per extra success in patients primarily treated with surgery was as high as USD 205.850.
The study concludes that nucleotomy, as a mini-invasive procedure with low complication rates and the potential of a quick recovery, is more cost-effective than traditional surgical treatment for lumbar disc herniation.
