Abstract
To assess the biomechanical and clinical evidence available in use and efficacy of interspinous fusion devices and to explore indications for their application. MEDLINE search and Google Scholar were employed to find the relevant papers through the following key words: interspinous fusion, interspinous fixation, and posterior instrumentation. Based on their fixation modes and fused sites, the related classification for interspinous fusion devices will be established, and a systematic review of clinical and biomechanical studies was made. The results revealed that a total of 13 kinds of interspinous fusion devices were obtained, and they were classified into two main categories: (1) “interspinous fixation without situ fusion” type (or rigid interspinous fusion device) and (2) “interspinous fixation with situ fusion” type (or fused interspinous fusion device). Furthermore, a summary on its biomechanical and clinical study was given, which showed that interspinous fusion device could provide excellent biomechanical efficiency and promising clinical success. In conclusion, interspinous fusion device construct is a new potential fixation technique. However, further high-quality studies are still needed to clarify their long-term efficacy and indications for their use.
Highlights
Since the spinal fusion was initially introduced by Hibbs and Albee in 1911, the technique of fusion has been one of the most prevalent methods for treating conditions of the spine including deformity, trauma, degenerative disc disease (DDD), and spondylolisthesis.[1]
The stiffness provided by SPP was in flexion– extension similar to bilateral pedicle screw (BPS) and was equivalent in lateral bending and axial rotation to unilateral pedicle screw (UPS) SPP’s amount of decrease in postoperative fused residual sagittal range of motion (ROM) was not as much as observed in pedicle screw group
ROM resulted from Affix was not in flexion– extension, was significantly different from BPS, and was in lateral bending similar to UPS
