ABSTRACT

BACKGROUND:

Lumbar arthroplasty is an alternative to fusion for the treatment of degenerative disc disease. Replacement of the nucleus pulposus preserves the biomechanical properties in the annulus and plates, conserving lumbar motion. Our objective was to evaluate the feasibility and clinical and radiological findings at 3 months follow-up with the Nubac device.

METHODS:

Ten patients from the National Institute for Rehabilitation (INR, Mexico City) with degenerative disc disease were selected to participate in the study. They underwent discectomy with Nubac device with a follow-up period of 3 months. Evolution was evaluated with the VAS and Oswestry scales.

RESULTS:

Five men and five women were included in the study (average age 41.6 years). Surgical approach was anterolateral (4 patients), posterior (3 patients) and anterior (3 patients), VAS improved from 8.1 to 2.5 (p <0.05) and Oswestry Disability Index (ODI) improved from 58.2% to 24.2% (p <0.05). Disc height before surgery was 9.4 mm, and 3 months postoperatively was 12.5 mm with no complications, migration, or subsidence.

CONCLUSIONS:

Nubac prosthesis improved lumbar discogenic pain in a short time when evaluated using ODI and VAS scales. Disc height improved after a 3-month follow-up, but lumbar motion did not improve. No complications have been reported; however, a minimum follow-up of 4 years is needed to make a definite conclusion.
