Lateral- or prone-position video-assisted thoracic surgery for dumbbell-type posterior mediastinal tumors: pros and cons.

ABSTRACT: Surgery for dumbbell-type posterior mediastinal tumors (D-PMTs) is difficult because surgeons should confirm the tumor's extension into the spinal cord and pay attention to the Adamkiewicz artery. We describe two patients of D-PMTs who underwent lateral- or prone-position video-assisted thoracic surgery (VATS). In patient 1 (a 70-year-old woman), the tumor extended to the spinal canal through the fourth thoracic intervertebral foramen. After hemi-laminectomies, she was moved to the lateral position, and the tumor was resected. In patient 2 (a 16-year-old boy), the tumor extended to the spinal canal through the seventh thoracic intervertebral foramen. Additionally, 320-row high-resolution computed tomography showed Adamkiewicz arteries running through the sixth and eighth thoracic intervertebral foramina. After laminectomy, the tumor was resected without repositioning. Prone-position VATS is a useful approach for D-PMTs because it provides a better view of the vertebrae compared with the lateral position. We discuss the advantages and disadvantages of both approaches.

Project description:BackgroundPosterior tibial plateau bicondylar fracture combined with anterior cruciate ligament injury, also known as the "Posterior Condylar Triad", is a regular combination injury. The traditional surgical strategy involves first fixing the posterior condyle in the prone position and then treating the anterior cruciate ligament avulsion injury after the patient turns over. This surgical strategy is cumbersome, requires multiple surgical preparations, prolongs the surgical time, and increases the patient's risk. Our centre proposed one lateral prone position with three incisions to treat the "Posterior Condylar Triad".MethodsThis was a retrospective analysis of the clinical data of 11 "Posterior Condylar Triad" patients who underwent surgical treatment at our centre from February 2017 to August 2020. Using a unified surgical strategy, the patient rotates the limb in a lateral prone position. The posterior condyle fracture of the tibial plateau is treated through a posterior medial incision and posterior lateral Frosch approach. Finally, anterior cruciate ligament avulsion fracture is treated through a small incision on the medial side of the patella. All patients were encouraged to perform functional exercises of the knee joint early after surgery. The postoperative complications (deep vein thrombosis, poor wound healing, deep infection, internal fixation failure and fracture reduction loss) and knee joint function (knee joint range of motion, Lysholm score and SF36 scale) of the patients were recorded 1 year after surgery.ResultsAll patients' fractures healed smoothly, with an average fracture healing time of 17.0 weeks, ranging from 12 to 22 weeks. There were 2 patients with deep vein thrombosis (DVT) after the operation. One patient experienced wound fat liquefaction, and no patients reported serious complications, such as loss of fracture reduction, failure of internal fixation, or deep infection. One year after surgery, the average range of motion (ROM) of the affected limb's knee joint was 3.6-120.5°, the average Lysholm score was 86.7, ranging from 61 to 100, and the average SF36 score was 76.96, with a range of 52.45-94.75.ConclusionThe "Posterior Condylar Triad" is a serious injury, and our proposed surgical strategy can simplify the surgical process, avoid large-scale changes in patient position during surgery, shorten surgical time, and reduce the risk of surgical anaesthesia, enabling patients to achieve good clinical prognosis.

Project description:Background and objectiveLateral access lumbar interbody fusion is an increasingly popular procedure that allows for anterior column support through discectomy, endplate preparation, and interbody insertion. This procedure was initially described and performed with the patient in the lateral decubitus position. This would typically be followed by repositioning the patient to the prone position for pedicle screw fixation. Increasingly common is the lateral access lumbar interbody fusion in the prone position. This narrative review seeks to summarize the available literature on advantages, disadvantages, and unique features of the prone position lateral access lumbar interbody fusion.MethodsWe performed a narrative review of articles published up to 01 November 2022 through a PubMed search. The search terms "prone lateral spine surgery" and "lateral approach spine surgery" AND "prone position" were used. Articles not available in English were excluded. The search result abstracts were independently reviewed by 2 authors and 28 full text articles were reviewed. Both reviewing authors were orthopedic surgery chief residents.Key content and findingsThere are several unique advantages as well as disadvantages to the prone position lateral interbody fusion. Some advantages include ease of placing pedicle screws, simultaneous posterior and lateral access, greater ease in achieving segmental lumbar lordosis, and a relatively safer positioning of the psoas muscle, lumbar plexus, and abdominal structures. Disadvantages include more difficulties with exposure and retraction, as well as visualization, positioning and ergonomics of surgery.ConclusionsProne position lateral interbody fusion is an increasingly prevalent and useful surgical technique with several advantages and disadvantages when compared to lateral interbody fusion in the lateral decubitus position. There are several surgical indications and goals for which prone lateral interbody fusion may provide significant benefit when compared to other interbody fusion techniques.
