Randomized Controlled TrialRole of Parecoxib Sodium in the Multimodal Analgesia after Total Knee Arthroplasty: A Randomized Double-blinded Controlled Trial.
Total knee arthroplasty (TKA) is an established surgical technique and is the standard treatment for degenerative knee joint diseases. However, severe pain after TKA makes it difficult for many patients to perform early postoperative rehabilitation and functional exercise, which might result in subsequent unsatisfactory recovery of knee joint function and great reduction in patients' satisfaction and quality of life. Orthopaedic surgeons have tried a large variety of analgesics and analgesic modes to relieve patients' pain after TKA. There are many analgesic regimens available in clinical practice but all have some deficiencies. Parecoxib sodium, a highly selective inhibitor of cyclooxygenase-2 (COX-2), can reduce the synthesis of peripheral prostaglandin to exert the effect of analgesia, and relieve inflammation and prevent central sensitization through inhibition of peripheral and central COX-2 expression. In addition, it can be used as a preemptive analgesic without affecting platelet aggregation. However, there does seem to be conflicting evidence in the current research as to whether parecoxib sodium can be used successfully as a preemptive analgesic; the effect of preemptive analgesia with parecoxib sodium in multimodal analgesia is still controversial. This research investigated the effects of parecoxib sodium in a preemptive multimodal analgesic regimen. ⋯ In preemptive multimodal analgesia regimens, parecoxib sodium can significantly decrease the VAS score in the short term, relieve pain shortly after surgery, and does not increase the incidence of complications. Parecoxib sodium is a safe and effective drug in the perioperative analgesic management for TKA.

Management of Dumbbell and Paraspinal Tumors of the Thoracic Spine Using a Single-stage Posterolateral Approach: Case Series.
This study investigated the surgical results of a single-stage posterolateral approach with arc incision, unilateral laminectomy, and costotransversectomy for the management of dumbbell tumors and paraspinal tumors of the thoracic spine. From January 2010 to March 2017, 14 patients with dumbbell tumors or paraspinal tumors of the thoracic spine who underwent resection with single-stage posterolateral approach were followed up and analyzed retrospectively. The operations were performed using a single-stage posterolateral approach with arc incision, unilateral laminectomy, and costotransversectomy without any instrumentation. ⋯ The 14 patients were followed up for 14-68 months (mean 39.4 months). At the final follow-up, no obvious spinal deformity or tumor recurrence was found in any patient except one with paraganglioma. Single-stage posterolateral approach is a good alternative surgical method for removing dumbbell tumors and paraspinal tumors of the thoracic spine without necessitating a subsequent anterior operation.
