Activities of Daily Living after Surgical Treatment for Osteoporotic Vertebral Fracture with or without Diffuse Idiopathic Skeletal Hyperostosis: A Retrospective Single-Institutional Study

摘要

Study Design This investigation was a retrospective observational study. Purpose The aim of this study was to evaluate whether having diffuse idiopathic skeletal hyperostosis (DISH) as a comorbidity affects the patient’s ability to perform activities of daily living (ADL) after surgical treatment for osteoporotic vertebral fracture (OVF). Overview of Literature A few studies have extensively evaluated elderly patients with comorbidities such as DISH and OVF-induced persistent back pain and their ability to perform ADL postoperatively. Methods In this study, 63 patients (21 men and 42 women) who underwent surgical treatment for OVF were enrolled. Of these patients, 26 had DISH (D ) and 37 did not have DISH (D-). Patient demographic characteristics and surgical, clinical, and radiological findings were compared between those with and without DISH. The change in their ability to perform ADL after surgery was also evaluated. Results Age, number of comorbidities, and 1-year mortality rate were significantly higher in the D group ( p 0.05). Postoperative Visual Analog Scale (VAS) scores were significantly higher in patients with impaired (n=6, p =0.04) abilities to perform ADL, and improvements in VAS scores were significantly higher in patients with unchanged abilities to perform ADL (n=54, p =0.03) after surgery. The average postoperative VAS scores were 2.2 for the D group and 2.3 for the D- group, which were not significantly different. Conclusions The frequency of OVF with DISH was higher in elderly men with multiple comorbidities and contributed to a higher 1-year mortality rate than those in patients without DISH. However, preoperative and postoperative VAS scores and improvements in VAS scores were similar between those with and without DISH. Postoperative impaired ability to perform ADL was associated with old age, high postoperative VAS scores, and little improvements in VAS scores, which were limitedly influenced by DISH. Surgical treatment of OVF combined with DISH is effective and appropriate for elderly patients.
