Full Percutaneous Treatment of Degenerative Disc Disease with Intradiscal Lumbar Interbody Fusion and Posterior Stabilization: Preliminary Results

Purpose To report the preliminary results of a novel full percutaneous interbody fusion technique for the treatment of degenerative disc disease (DDD) resistant to conservative treatment with posterior stabilization with rods and screws and transforaminal placement of an 8-mm-width intradiscal cage. Materials and Methods A total of 79 patients with lumbar spine DDD resistant to medical therapy and/or spondylolisthesis up to grade 2 were treated. We performed preoperative X-rays, CT and MRI. The outcomes were assessed using the VAS score and the Oswestry Disability Index at a 1-, 6- and 12-month follow-up and also included X-rays to evaluate the correct bone fusion and the absence of complications. Results Mean operation time was 130 min, and mean postoperative time until hospital discharge was 2 days. Postoperative values for VAS scores and ODI improved significantly compared to preoperative data: Mean preprocedural VAS was 7.49 +/- 0.69 and decreased at 12-month follow-up to 1.31 +/- 0.72, and mean preprocedural ODI was 29.94 +/- 1.67 and decreased at 12-month follow-up to 12.75 +/- 1.44. No poor results were reported, and no postprocedural sequelae were observed. Conclusions In our experience, this preliminary report shows a feasible and safe full percutaneous alternative procedure and represents a minimally invasive management of degenerative disc disease with low back pain resistant to medical therapy with or without lumbar spondylolisthesis up to grade 2.
