Introduction: Previous studies have reported various factors related to the prognosis after lumbar spine surgery. However, it is unclear to what extent each factor affects the postoperative outcome. This study aimed to clarify the factors affecting postoperative hospitalization using preoperative physical function, a questionnaire, intraoperative information, and patient information as independent variables.
Methods: This study comprised 115 patients with lumbar spinal canal stenosis and herniation of lumbar discs who underwent posterior lumbar spinal decompression (n = 46) and fusion surgery (n = 69) at our hospital. At the time of the surgery, the average age of the 48 men and 67 females was 63.4±17.4 years. Physical functions, including 6-min walk test (6MWT) and Manual Muscle Test (MMT), were performed before the surgery. The questionnaire included the RDQ, which was provided before the surgery. Additionally, we investigated operative information (the presence or absence of fusion surgery) and patient information (BMI, gender, and the number of days to acquire ambulation). Multiple regression analysis was performed with these factors as the independent variables and the duration of hospitalization as the dependent variables.
Results: The number of days to acquire ambulation, the presence or absence of fusion surgery, age, and the muscle strength of the hip extension were found to be significant related factors (p < 0.01).
Conclusions: The factors influencing the duration of hospitalization following lumbar spine surgery were identified in this study. The duration of hospitalization depend on the prolonged walking acquisition period, the fusion surgery, old age, and the weakness of hip extension muscles.
