Surgical Outcome of Degenerative Spinal Stenosis Clinical: Clinical Correlation of Patient Satisfaction and Surgical Results / 대한척추외과학회지

ABSTRACT

STUDY DESIGN: This study is a retrospective evaluation of the surgical outcome by the patient satisfaction and Oswestry low back pain questionnaire. OBJECTIVE: The goal of this study was to evaluate the clinical correlations of various factors with the patient's satisfaction and with the surgical results in degenerative spinal stenosis. SUMMARY OF LITERATURE REVIEW The patients satisfaction and surgical outcome of the degenerative spinal stenosis by the objective method have not been well described in the literature. MATERIAL AND METHODS: Mean follow-up period was 4.8 years after surgery in 114 patients. Outcome was based on subjective disability using Oswestry low back pain questionnaire. Patient satisfaction degree was rated to 'very satisfied(1)', 'somewhat satisfied(2)', 'somewhat dissatisfied(3)' and 'very dissatisfied(4)'. Several factors that might be associated with patient satisfac-tion and outcome were investigated. RESULTS: Of the one hundred and fourteen patients, 84(73.9%) were satisfied to the surgery and mean satisfaction degree was 1.94. Ninety two patients(80.7%) had excellent-to-good results with the mean Oswestry disability score 26.9. There were 7 complications including dural tear in 3 cases, pseudarthrosis in 1 case, dissociation between rod and screw in 1 case, pedicle screw breakage in 1 case and termination of operatin due to massive bleeding during operation in 1 case. CONCLUSION: Clinical results and patient satisfaction were better in the cases with short segments fusion than long segments fusion and the patients with preoperative leg symptom as major symptom had significantly lower Oswestry disability score.
