Filter by:Background : Segmental spinal instability after a laminectomy, and adjacent segment disease (ASD) at after an arthrodesis, are well-known concerns in spinal surgery, which may require re-interventions, usually by surgical arthrodesis, posing the problem of a new heavy intervention under general anesthesia, in often fragile patients. Trans-facet fixation (TFF) under local anesthesia and double fluoroscopic and CT guidance is a minimally invasive technique involving the placement of screws through the posterior facet joints, improving spinal stability. Purpose : The aim of our study is to evaluate the efficacy, in terms of pain reduction (VAS) and improvement of daily activities (ODI), of TFF under CT scan guidance in the context of low back pain and/or radiculalgia related to focal instability secondary to laminectomy or ASD. Methods : TFF were performed in 24 patients having a history of spinal surgery such as laminectomy and/or classic surgical arthrodesis and remaining symptomatic, at Nice University Hospital between 2017 and 2021 Pre- and postoperative pain and disability levels were measured using the visual analogue scale (VAS) and the Oswestry Disability Index (ODI), collected prospectively at systematic 6-month and 1-year follow-up visits. Long term evolution were assessed by phone consultation.
This observational study aims to determine the efficacy and safety of the Shark Screw® transplant for osteotomy and arthrodesis in hand and foot surgery.
The goal of this research study is to determine the change in frontal plane rotation of the 1st metatarsal from pre to post arthrodesis of the 1st TMT joint with the Phantom® Intramedullary Nail combined with a supinating reduction technique. The study hypothesis is that multi-planar correction can be achieved with the Phantom® Intramedullary Nail.
Ultrasonic bone osteotome has been utilized in various surgical field, but the use in neurosurgery especially in spine surgery is not widely spread. In the present study, the investigators are going to compare bony fusion rate after cervical laminotomy either with ultrasonic osteotome or conventional drill.
