- Primary Outcome Measures
Name Time Method Oswestry disability index (ODI) at 1 year after surgery The ODI is based on a self-administered questionnaire measuring ''back-specific function.'' The questionnaire comprises 10 items, each with 6 levels of response. Each item is scored from 0 to 5, and the total summation is converted to a 0-100 scale. The ODI scores ranges from 0 to 100, with higher scores indicating severe symptoms.
This is assessed by ODI survey at 1 year after surgery
- Secondary Outcome Measures
Name Time Method Operation duration time (minutes) Immediate after operation Intraoperative time in minutes
Change from baseline Oswestry disability index (ODI) 3, 6, and 12, months, and every year, up to 5 year after operation The ODI is based on a self-administered questionnaire measuring ''back-specific function.'' The questionnaire comprises 10 items, each with 6 levels of response. Each item is scored from 0 to 5, and the total summation is converted to a 0-100 scale. The ODI scores ranges from 0 to 100, with higher scores indicating severe symptoms.
Change from baseline EuroQoL-5 dimension (EQ-5D) value 3, 6, and 12, months, and every year, up to 5 year after operation EQ-5D is a standardized instrument developed by the EuroQol Group as a measure of health-related quality of life that can be used in a wide range of health conditions and treatments. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Rated level can be coded as a number 1 to 5, which indicates having no problems for 1, and having extreme problems for 5. As a result, a person's health status can be defined by a 5-digit number, ranging from 11111 (having no problems in all dimensions) to 55555 (having extreme problems in all dimensions). EQ-5D health states may be converted into a single index value. The index values are a major feature of the EQ-5D instrument, facilitating the calculation of quality-adjusted life years (QALYs) that are used to inform economic evaluations of health care interventions. The value sets are anchored on 11111 = 1 and 55555 = 0 and can therefore be used in QALY calculations.
Change from baseline PainDETECT score 3, 6, and 12, months, and every year, up to 5 year after operation The painDETECT Questionnaire (PDQ) is a screening tool designed to detect neuropathic pain in patients with chronic low back pain (LBP) based on self-reported pain characteristics. The degree of the seven types of pain quality, the type of pain pattern, and the presence of radiating pain. From the three components of the PDQ, a total score is calculated; a high score indicates that the pain is likely to have a neuropathic component. Scoring is performed using a scoring manual, and results in a final screening score: a score of 0-12 indicates nociceptive pain, 19-38 indicates neuropathic pain, and 13-18 indicates mixed pain.
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 up to 1 month after operation Surgery related adverse events (incidental durotomy, wound infection, re-operation, re-admission)
Volume of postoperative drainage (ml) Within 3 days after operation Total drainage after surgery in milli-liter
Number of participants with complete discectomy Within 3 days after operation After surgery, degree of discectomy was measured using postoperative MRI
Concentration of creatine phosphokinase level in blood At 2 day after surgery Creatine phosphokinase assessment to measure muscle injury at operation
Times of hospital stay (hours) Within 7 days after operation Total hospital stay after surgery
Volume of postoperative Fentanyl consumption At 3 days after operation Total amount of fentanyl consumption after surgery (PCA dose + rescue dose)
Number of radiographic complications every year, up to 5 year after operation Radiographic complications includes disc degeneration, facet degeneration, re-ruptured disc, back muscle atrophy, kyphotic change, disc rupture...
Change from baseline Visual Analog Pain Scale (VAS) 4, 8, 12, 24, 48 hours, 2 weeks, 3, 6, and 12, months, and every year, up to 5 year after operation VAS is a measurement score that indicates pain severity status. VAS score comprised a 10-cm line with ''none'' (0) on one end of the scale and ''disabling pain'' (10) on the other.
