Risk factors for poor outcomes of early rehabilitation after total en bloc spondylectomy: a retrospective chart review of 140 patients.

Abstract

A retrospective chart review. Total en bloc spondylectomy (TES) has been reported to decrease the rate of local recurrence and increase survival. Although it is important to achieve early recovery of physical functions after surgery, no studies have evaluated rehabilitation outcomes during the acute phase after TES. This study evaluated ambulatory functions and activities of daily living (ADLs) after surgery and analyzed the prognostic significance of variables affecting rehabilitation outcomes at 1 month after TES. University hospital in Kanazawa, Japan. This study included 140 patients with spinal tumors who underwent TES between April 2010 and April 2017. Demographic characteristics, neurological functions, perioperative complications functional status as measured by the Functional Independent Measure, and independent indoor walking based on the Spinal Cord Independent Measure were extracted from medical records. Multivariate analyses were performed to assess factors associated with the recovery of ambulation and ADL at 1 month after TES. Preoperative neurological deficits were observed in 51 patients (36%), and postoperative neurological deterioration was found in 41 patients (29%). Multivariate analyses indicated that preoperative neurological deficits (odds ratio [OR], 5.23; 95% confidence interval [CI], 2.07-15.99), postoperative cerebrospinal fluid leakage (OR, 13.42; 95% CI, 2.93-78.82), surgical site infections (OR, 15.27; 95% CI, 2.26-127.7), and postoperative neurological deterioration (OR, 4.86; 95% CI, 1.33-19.99) were risk factors for walking ability and recovery of ADL (P < 0.01). This study identified preoperative neurological dysfunction and perioperative complications as independent risk factors for poor recovery of ambulation and ADL early after TES.
