Background: The femur is the most common long bone affected by metastatic bone disease, with 25% involving the proximal third of the femur. Long stem cemented hip replacement (LHR) is an important option for cases of impending fracture. Pulmonary embolism is a critical complication that can occur. This study evaluates the effectiveness of distal femoral canal decompression in reducing the risk of cardiopulmonary events.

Materials And Methods: Thirty two patients with metastatic bone disease of the proximal femur undergoing LHR were recruited and randomized. Conventional technique was used in 16 cases and distal decompression of the medullary canal was carried out for the other 16 patients. The decompression was carried out through a trocar inserted into the distal medullary canal, connected to a vacuum suction. Quantity of emboli was detected through A4 chambers transesophageal echocardiography; the blood pressure and oxygen saturation readings were also recorded.

Results: The decompression group experienced significantly lower Grade 2 and Grade 3 embolic events compared to the conventional group (11 vs. 26), and the duration of the embolic phenomena was shorter. Insertion of the stem and relocating the hip gave the highest amount embolic events. There was a significant drop in systolic blood pressure (SBP) in 12 out of 16 patients (75.0%) in the conventional group and 5 out of 16 patients in the decompression group (31.3%). This is statically significant ( = 0.0124). The average drop in SBP for the conventional group is 45.8 mmHg and the decompression group was 32.9 mmHg. Oxygen saturation remained at above 96% in the decompression group. However, in the conventional group, 25% of the patients had their oxygen saturation drop to below 96% during the insertion of stem and relocation of hip joint.

Conclusion: Distal femoral canal decompression is an effective method in reducing the risk of cardiopulmonary embolic events associated with LHR.

Background/aim: The effectiveness of a transanal drainage tube (TAT) for the prevention of anastomotic leakage after double stapling technique (DST) anastomosis in colorectal cancer has been reported. Previously, TATs had been placed and connected to drainage bags. It was considered that a higher decompression effect could be expected by inserting an open-type TAT, without connection to a drainage bag.

Objective: Many patients with ruptured intracranial aneurysms (RIAs) underrepresented or excluded from previous randomized controlled trials (RCTs) comparing surgery with endovascular treatment (EVT) are still considered for surgical clipping, but the best management of these patients remains unknown.

Methods: The International Subarachnoid Aneurysm Trial-2 was a randomized trial comparing surgical versus EVT of RIAs considered for surgical clipping, despite the results of previous RCTs, and also eligible for EVT. The primary endpoint was death or dependency according to the modified Rankin Scale score (mRS score > 2) at 1 year.

Background: Posterior laminectomy is a standard treatment for thoracic ossification of the ligamentum flavum (TOLF), but it often leads to neurological deterioration during surgery. This study aimed to reduce iatrogenic neurological deterioration by using an S8 navigation system combined with an ultrasonic osteotome for three-dimensional real-time dynamic visualization decompression.

Methods: A retrospective analysis was conducted on patients who underwent laminectomy and internal fixation for TOLF in our centre from January 2016 to January 2023.

Multilevel lumbar spinal stenosis (LSS) is a prevalent degenerative condition characterized by lower back pain, intermittent claudication, and radicular leg pain. It ranks as one of the primary indications of spinal surgery in patients aged 65 and older. In this study, we aim to compare single-level and multilevel approaches for decompression alone in LSS considering the incidence of complications, reduction in pain score, and rates of surgical revisions.

Currently there is not a clear basis of evidence for post-operative antibiotic duration in spine surgery. A better understanding of risk factors and proper dosing for antibiotics will help improve outcomes and further define appropriate antibiotic use. A single-center retrospective cohort study of all patients undergoing spinal fusions and/or decompressions between January 1, 2018, and July 1, 2023 was performed.
