BACKGROUND
The aim of the study is to analyse the functional outcome of spondylolisthesis treatment by posterolateral fusion and pedicle screw-rod instrumentation with decompression produced at AVMC and Hospital in period between May 2013 to July 2016 are to be analysed.(1)
MATERIALS AND METHODS
This is retrospective and prospective study comprising of 20 patients with spondylolisthesis who were treated with posterolateral fusion with Zeta Rods and pedicle screw fixation at Aarupadai Veedu Medical College and Hospital during the period between May 2013 to July 2016. These patients were reviewed periodically both clinically and radiologically for a minimum of 6 months following operative fixation.
Inclusion Criteria-
ï?· Patients in the age group of 30-60 days.
ï?· All cases of spondylolisthesis.
Exclusion Criteria-
ï?· Inoperability in certain cases due to multiple comorbid factors/systemic disease.
ï?· Bed ridden patients.
RESULTS
ï?· The follow up ranged from 6 to 10 months with an average follow up of 7.67 months.
ï?· Reduction of listhesis.
ï?· The following parameters are calculated to determine the correction of slip.
ï?· Fusion.
ï?· The average time taken for fusion is six months. The fusion was solid in 13 patients (65%), possibly solid in 6 patients (30%) and 1 case of pseudoarthrosis (5%).
CONCLUSION
Our study is a retrospective and prospective study, which was conducted at Aarupadai Veedu Medical College and Hospital to analyse the functional outcome in twenty cases of degenerative spondylolisthesis who were treated by posterolateral fusion and pedicle screw (2) - rod instrumentation as a definitive treatment modality.
