Postoperative clinical outcomes with and without short-term intravenous tranexamic acid after posterior lumbar interbody fusion: A prospective cohort study.

The use of tranexamic acid (TXA) in posterior lumbar interbody fusion (PLIF) surgery is believed to be beneficial for reducing intraoperative blood loss, postoperative drainage volume (PDV), and length of hospital stay (LOS). However, whether continued administration of intravenous TXA within 24 hours after surgery is more beneficial to patients has not yet been studied. This study prospectively analyzed the perioperative outcomes of patients who received and did not receive intravenous TXA within 24 hours after PLIF (≥2 segments) surgery from January 2018 to December 2021.

Risk factor of residual leg numbness after lumbar microdiscectomy for lumbar disc herniation.

Although patients with lumbar disc herniation (LDH) can achieve significant relief from lower back and leg pain after lumbar microdiscectomy, a few patients complain of discomfort due to residual leg numbness (RLN). This study aimed to identify potential risk factors for RLN after lumbar microdiscectomy. We prospectively collected and analyzed patients with LDH who underwent microdiscectomy between September 2016 and December 2020.

Ulnar impaction syndrome with different operative methods: a comparative biomechanical study.

Objective: Ulnar impaction syndrome seriously impairs wrist and hand function. Three main treatment procedures are available; however, little systematic research on the post-operation changes in wrist biomechanics currently exists. This study aimed to determine the long-term effects of these procedures and the optimal treatment methods for ulnar impaction syndrome.

Establishing a rat model of spastic cerebral palsy by targeted ethanol injection.

Spastic cerebral palsy is generally considered to result from cerebral cortical or pyramidal tract damage. Here, we precisely targeted the left pyramidal tract of 2-month-old Sprague-Dawley rats placed on a stereotaxic instrument under intraperitoneal anesthesia. Based on the rat brain stereotaxic map, a 1-mm hole was made 10 mm posterior to bregma and 0.
