Patients with spinal stenosis with concomitant degenerative spondylolisthesis (DS) and predominant back pain (PBP) have been shown to have inferior outcome after surgery. Studies comparing outcome according to preoperative pain predominance and treatment received are lacking. ⋯ Patients with PBP operated with DF report better outcomes in terms of pain, function, and health-related quality of life than patients with D. Although these differences are significant on a group level, they may fail to reach minimal clinical significant difference. Patients with PLP report significantly more improvement in terms of BP with DF compared with D, but because of baseline differences in preoperative BP, these improvements may not be explained by the added fusion per se. At the 2-year follow-up, no significant differences were observed between the D and DF patients in either the PBP or PLP groups, but greater loss to follow-up in the DF groups could potentially bias these findings.

The Scoliosis Research Society 22 Questionnaire (SRS-22) has shown to worsen with increasing deformity in adolescents with idiopathic scoliosis (AIS). However, all the studies have been performed on patients who have already been diagnosed and in relatively small samples. ⋯ According to our results, deformity is apparently not a real issue for AIS before diagnosis made, treatment planned, and/or specialists interfere with their everyday life. Scoliosis Research Society 22 Questionnaire demonstrated some discriminative validity between small and large curves, but the differences found were small.

Randomized Controlled Trial Comparative Study
Comparison of the lumbar disc herniation patients randomized in SPORT to 6,846 discectomy patients from NSQIP: demographics, perioperative variables, and complications correlate well.
The Spine Patient Outcomes Research Trial (SPORT) is a highly referenced clinical trial that randomized patients with lumbar pathology to receive surgery or continued conservative treatment. ⋯ Spine Patient Outcomes Research Trial lumbar disc herniation results are similar to those from a large national patient sample. Even statistically significant differences would be considered clinically similar. These findings support the generalizability of the SPORT lumbar disc herniation results.

Spine surgery is usually associated with large amount of blood loss, necessitating blood transfusions. Blood loss-associated morbidity can be because of direct risks, such as hypotension and organ damage, or as a result of blood transfusions. The antifibrinolytic, tranexamic acid (TXA), is a lysine analog that inhibits activation of plasminogen and has shown to be beneficial in reducing surgical blood loss. ⋯ Tranexamic acid reduces surgical bleeding and transfusion requirements in patients undergoing spine surgery. Tranexamic acid does not appear to be associated with an increased incidence of pulmonary embolism, DVT, or MI.

Adverse events (AEs) in thoracic and lumbar spine fractures are common, but little is known about the type of AEs that are specific to this population. Furthermore, very little is known about the incidence and clinical impact of these AEs on patients in the presence of traumatic spinal cord injury and whether they are treated operatively or nonoperatively. ⋯ The presence of neurologic injury and the need for operative fixation of thoracic or lumbar injuries lead to a greater risk of AEs. Only pneumonia and delirium consistently increase LOS.
