Background

Wallis implant was developed in 1986 to stiffen unstable operated degenerate lumbar segments while preserving some intervertebral mobility. The long-term results of first-generation Wallis implant from developers were promising. However, documentation pertaining to safety and efficacy of second generation Wallis implant is sparse in literature.

Purpose

The objective of this study was to assess the clinical outcome of the second generation Wallis interspinous device for degenerative lumbar disc disease.
