Surgical outcomes of single stage surgery for Tandem spinal stenosis (TSS) in elderly and younger patients: A comparative study.

STUDY DESIGN

Retrospective study.

OBJECTIVE

To evaluate and compare the outcomes of single stage surgery for Tandem Spinal Stenosis (TSS) in elderly (Age ≥65 years) and younger patients (Age <65 years).

SUMMARY OF BACKGROUND DATA

Tandem spinal stenosis among elderly is common and often missed diagnosed with delayed presentation. Literature evaluating efficacy and safety of single staged surgery for TSS in elderly patients is scanty.

METHODS

Analysis of 74 patients with TSS managed with single stage posterior surgery from 2007 to 2016 was done. A total of 62 patients who satisfied our inclusion criteria were evaluated and subdivided into two groups based on age; Study group (age ≥65years)] (n = 32) and control group (age <65years) (n = 30). Perioperative, clinical/radiological parameters and postoperative complications and recovery rate were noted.

RESULTS

The Mean ODI and mJOA showed significant improvement post-operatively in both groups however there was no significant difference between the two groups at final follow-up. There was no statistical difference in operative time, blood loss and hospital stay between the groups. As per Odom's criteria, 78.1% had excellent to good results in study group, while 83.3% had excellent to good results in control group. Postoperative complications were more in elderly group however, there was no significant difference among neurological or cardiopulmonary complications between both groups.

CONCLUSIONS

Single stage surgery is safe & efficacious modality with less morbidity and optimal results in elderly patients with proper preoperative risk assessment. Our study showed that increased age does not proved to be deterrent in the outcome of single staged surgery in tandem spinal stenosis.
