Risk factors of unintended return to the operating room in adult spinal deformity

Abstract Background To evaluate the incidence and risk factors associated with unintended return to operating room in adult spinal deformity after corrective surgery. Methods Retrospect of 141 patients a single institution between January 2017 December 2019. Inclusion criteria enrolled 18 80 years old who diagnosed congenital/idiopathic/syndromic/acquired underwent posterior The surgical details complications were recorded. rate (UIROR) during hospitalization was examined, investigated via multivariate analysis. Results This is retrospective study. One hundred forty-one surgery mean age 31.8 (range 18-69 years) studied. 10.64% (15/141). Two 15 had twice (13.33%). most principal complication neurologic deficit (73.3%); six postoperative present implants deviation causes severe lower limbs radiating pain (40%). analysis shows higher apical vertebral rotation (AVR>grade II, odds ratio [OR] = 9.362; 95% CI= 1.930-45.420; P .006), obesity (OR 11.448; 1.320-99.263; .027), previous neurological symptom 7.358; 1.798-30.108; .006) independent predictors room. Conclusion Postoperative short-term implant malposition are essential patients. Preoperative such as AVR (> grade II), obesity, may significantly increase morbidity UIROR. Spine surgeons should be alert these require adequate preoperative evaluations reduce
