Objective To evaluate the effect of surgical reconstruction of extracranial vertebral artery and to summarize the experience. Methods The clinical data of 15 patients undergoing surgical reconstruction of extracranial vertebral artery from September 2018 to June 2022 were collected.The operation methods,operation duration,intraoperative blood loss,operation complications,and relief of symptoms were retrospectively analyzed. Results Eleven patients underwent vertebral artery (V1 segment) to common carotid artery transposition,two patients underwent endarterectomy of V1 segment,two patients underwent V3 segment to external carotid artery bypass or transposition.The operation duration,intraoperative blood loss,and blocking time of common carotid artery varied within 120-340 min,50-300 ml,and 12-25 min,with the medians of 240 min,100 ml,and 16 min,respectively.There was no cardiac accident,cerebral hyperperfusion syndrome,cerebral hemorrhage or lymphatic leakage during the perioperative period.One patient suffered from cerebral infarction and three patients suffered from incomplete Horner's syndrome after the operation.During the follow-up (4-45 months,median of 26 months),there was no anastomotic stenosis,new cerebral infarction or cerebral ischemia. Conclusion Surgical reconstruction of extracranial vertebral artery is safe and effective,and individualized reconstruction strategy should be adopted according to different conditions.

Purpose: To investigate the rate and timing for return to football league games after anterior cruciate ligament reconstruction (ACLR) in Swedish players, examining associations with sex, age, level, graft and additional ACL surgery.
Method: Data from the Swedish National Knee Registry (SNKLR) and the Swedish Football Association's IT System (FOGIS) were used. The study cohort comprised 971 football players, 64% males, who underwent primary ACLR.
Financial Impact of Medicare Payment Reform for E/M Visits on Compensation for Otolaryngologic Procedures in 2023.

The Centers for Medicare & Medicaid Services (CMS) recently increased payment for evaluation and management (E/M) visits, but did not apply these updates to post-operative global period visits. We investigated the resulting Medicare fee-for-service revenue loss for otolaryngologists. Using publicly available Medicare spending/utilization data, we estimated how much additional payment otolaryngologists would have received in 2023 if CMS had reimbursed global period visits at the same rates as other E/M visits.

Objective: The optimal method for maintaining intraoperative blood pressure during microsurgical procedures remains controversial. While intravenous fluid administration is essential, overfilling can lead to complications. Vasopressor agents are used cautiously due to their vasoconstrictive effects, which could potentially lead to flap failure.

Background: Spacer-type tibial osteotomy have been proven a novel and effective osteotomy to treat osteoarthritis, while lack of comparison with other surgical methods in younger patients. This study aims to evaluate the short-term clinical outcomes of spacer-type tibial osteotomy versus open wedge high tibial osteotomy (OWHTO) and unicompartmental knee arthroplasty (UKA) for Kellgren-Lawrence (K-L) grade 3-4 osteoarthritis (OA) in patients younger than 65 years.
Methods: This retrospective study analyzed a total of 224 patients with K-L grade 3-4 knee OA treated from March 2018 to November 2020.

Background: Prospective trial evidence is lacking regarding the application of enhanced recovery after surgery (ERAS) in transvaginal pelvic floor reconstruction surgery among older patients. Our study aimed to investigate whether implementing the ERAS protocol could enhance post-operative recovery in this patient population.
Methods: Older patients undergoing elective transvaginal pelvic floor reconstruction surgery were randomly assigned to either the ERAS group or the conventional group.
