Introduction: To evaluate long term results after one and two level anterior cervical discectomy and fusion (ACDF) with stand-alone Empty PEEK cages
Methods: We performed a retrospective review of a consecutive patient cohort that underwent ACDF with stand-alone empty PEEK cages between 2007 and 2010 with a minimum of 12 Months. Radiographic follow-up included static and flexion/extension radiographs. Changes in the operated segments were measured and compared to radiographs directly after surgery. Clinical outcome was evaluated by a physical exam, pain VAS and the EuroQOL questionnaire (EQ-5D).
Results: From 359 consecutive cases, 49 were foreigners and 11 were dead due to surgery unrelated reasons.
Follow up data was obtained from 256 out of 299 eligible patients (86%). The mean age at presentation was 55 years, 131 patients were male (51%). 137 and 119 patients had one- two-level surgeries, respectively. 125 (48%) presented with spondylotic cervical myelopathy and 131 (52%) with cervical radiculopathy.
Fusion was achieved in 97% and 95% levels in one- and two-level surgeries, respectively. The alignment of the whole cervical spine worsened in 21 (15%) and 19 (16%) in one and two level surgeries, respectively (according to the Katsuura and Laing methods). Follow up operations for symptomatic adjacent disc disease or implant failure at index level were needed in 10 (4%) and 3 (1%) cases, respectively. Mean VAS declined from 6,7 to 2,2. Improvement or stability was observed in all dimensions of the EQ-5D.
Conclusions: One and two level ACDF with stand-alone empty PEEK cages achieved very high fusion rates, low rate of follow up operations. The rate of clinical Outcome is highly satisfactory.
Patient Care: By providing others with the clinical and radiological outcome of ACDF without ventral platting.
Learning Objectives: By the conclusion of this session, participants should be able to know the significance of the radiological outcome with regards to the clinical outcome following an anterior cervical discectomy and fusion with PEEK cages.
