Abstract:

Objective

To investigate the short-medium term clinical outcome of the BacFuse interspinous implantation

for treatment of the degenerative lumbar spondylolisthesis in the elderly.

Methods

From January 2014 to June 2015, 32 patients with degenerative lumbar spondylolisthesis were surgically treated with BacFuse interspinous implantation, including 15 males and 17 females with a mean age of67.35.1years. In them, Grade I of spondylolisthesis was found in 29 segments while Grade II in 11 segments. Pre- and postoperatively, the VAS, ODI and JOA were used to assess clinical symptom and physical function. The posterior disk height, foraminal height, range of motion and the relative displacement between the upper and lower vertebral body were measured in X-ray film.

Results

The operation lasted55.012.4minutes with blood loss of 49.819.9ml on average without severe surgical complication . All the patients were followed up for an average of 15.65.0months. At the latest follow-up, VAS significantly decreased from 6.751.39preoperatively to 2.411.78P< 0.05, likewise ODI considerably decreased from35.4711.15to13.227.66P<0.05, whereas the JOA statistically increased from12.251.52to24.163.46P<0.05. In term of radiographic measurements, the posterior disk height significantly increased from6.752.43mm to8.442.56mmP<0.05, the foraminal height increased from19.983.34mmto21.722.74mmP<0.05,whereastherangeofmotioninaffectedsegmentsdecreasedfrom15.954.31 to 3.751.36 P<0.05, additionally, the relative displacement between the upper and lower vertebral body decreased from5.020.93mm to0.350.27mmP<0.05.

Conclusion

BacFuse interspinous implantation for treatment of the degenerative lumbar spondylolisthesis with advantages of shortened operation time, diminished blood loss, and reliable outcome,isasafesurgicalprocedure for the elderly.
