Filter by:To implant a complete lumbar disc prosthesis removal of the anterior portion of the annulus fibrosus is required. As the anterior portion of the annulus limits the movement in extension and axial rotation, we would like to know how much increase these two disc movements and also the effect on the postoperative prevertebral scar on the reduction of these abnormal movement ranges. We also aim to see if repairing intraoperatively the anterior portion of the annulus has any advantage in the final result achieved.
High blood pressure is a serious and common health problem. This disease affects 1 billion people all over the world and responsible for 7,1 million deaths. Trials involving more than 1 million people state that stroke incidence rises as blood pressure rises. The effects of high blood pressure on cerebral perfusion is not well realized. Intraoperative blood pressure management of patients with high blood pressure is not well known. And it is still not clear how autoregulation of cerebral perfusion is affected by high blood pressure. Systemic arterial pressure changes have little effect on cerebral perfusion. This is regulated by changes of precapillary resistance. When systemic arterial blood pressure drops, it is regulated by vasodilatation of arteriolar smooth muscles. And when systemic blood pressure rises, it is regulated by vasoconstriction of arterioles. Cerebral perfusion is well preserved between 50-125 mmHg changes of mean arterial blood pressure (MAP). Patients with high blood pressure have higher ranges. Patients with chronic high blood pressure can better tolerate higher blood pressures. But even physiologic drops of systemic blood pressure can cause ischemia. Anesthetic drugs have variable effects on cerebral blood flow and physiology. The drugs used with anesthetic drugs, the noxious stimulus of surgery, intracranial compliance, blood pressure, and carbon dioxide pressure can all alter and complicate these effects. Anesthetic drugs must be selected carefully in patients with high blood pressure. It is still investigated whether, management of blood pressure under anesthesia, should be individualized. For patients with high blood pressure, some neuromonitorization technics have been evaluated to prevent neurologic complications under anesthesia. But there is not a technic, which is considered as a gold standard. Cerebral blood pressure has been studied by, nitrous oxide method, krypton uptake method, and xenon injection methods previously. Near-infrared spectroscopy (NIRS) is the best monitorization technic of intracranial pressure (ICP), cerebral blood flow (CBF), and cerebral metabolism. But it can not be applied to all patients. Recently, it is possible to measure blood flow of cerebrum with transcranial Doppler ultrasound in anesthesia practice. In this trial, the investigators aim to evaluate cerebral perfusion of hypertensive patients with transcranial Doppler during lumbar disc surgery to optimize the blood pressure under anesthesia. To best of our knowledge, there is no trial evaluating cerebral perfusion of hypertensive patients with transcranial Doppler ultrasound.
Monocentric, comparative, randomized, controlled interventionnal study in 2 parallel groups, aiming to compare the efficacy of the ATLAS device with that of a standard lumbar belt on the reduction of pain felt in patients with subacute or chronic low back pain with lumbar disc disease.
The purpose of this study is to determine if treatment with low-dose oral propranolol in the days before and after surgery decrease postoperative pain and improve pain scores.
122 ASA I-II patients were enrolled into the study. IV propofol, fentanyl and rocuronium were used for the induction and a total intravenous anesthesia technique for the maintenance of anesthesia. Sugammadex was given for neuromuscular blockade reversal. A multi-modal analgesic regimen was utilized. Primary outcome measures were PACU bypass rates and hospital discharge times. Secondary outcome measure was to compare discharge scoring systems for PACU bypass assessment: modified Aldrete Scoring System (mASS), White's Fast-Tracking Scoring System (WFTSS), and SPEEDS criteria
The purpose of this study is to prospectively review outcomes of patients who have surgery with the ExcelsiusGPS™ robotics system in order to analyze screw placement accuracy. Patient demographics, intraoperative data and radiographic imaging to determine screw placement accuracy will be collected and reviewed. This information will be compared in a separate study to retrospectively collected data from sites who have done a similar number of cases without the robot.
Ultrasound (US)-guided peripheral nerve blocks have been used increasily due to the advantages of ultrasound in anesthesia practice. TLIP block is one of these nerve blocks performed under US guidance. In this technique, local anesthetic solution is injected between the multifidus and logissimus muscles nearly at the level of the 3rd lumbar vertebra and targets the dorsal rami of the thoracolumbar nerves. However, the visualisation of this technique may be difficult under US guidance. Therefore, modified-TLIP (mTLIP) block was defined as a new approach. It has been reported that mTLIP block may provide effective analgesia management after lumbar spine surgery. The ultrasound (US) guided erector spina plane block (ESPB) is a novel interfacial plan block defined by Forero et al. at 2016. Visualization of sonoanatomy with US is easy, and the spread of local anesthesic agents can be easily seen under the erector spinae muscle. Thus, analgesia occurs in several dermatomes with cephalad-caudad way. It has been reported that ESPB provides lumbar analgesia at T10-12, L3. The aim of this study is to compare US-guided mTLIP block and ESPB pain management after multi-level lumbar spinal instrumentation surgery.
Investigators team propose to evaluate the impact of the use of intraoperative scanning coupled with Stryker navigation, compared to the conventional fluoroscopy technique, on the accuracy of pedicle screws, in instrumented spinal surgery, by a randomised prospective study, in terms of pedicular screw accuracy. We will also evaluate the radiation exposure of the neurosurgical team and the patient in these two techniques.
The primary objective is to determine the validity of the Six-Minute-Walking Test (6WT) and Timed-Up and Go (TUG) test to measure objective functional impairment (OFI) in patients undergoing either interlaminar epidural steroid injection (ESI) or transforaminal epidural steroid injections (TFESI) for lumbar degenerative disc disease (DDD)
The aim of this study is to compare the effectiveness of four physical therapy treatment approaches for lumbar region pathologies. Eighty volunteers who have back pain will be included in the study. Subjects will be randomly divided into four groups; Group 1: Soft tissue mobilisation techniques and stabilization exercises (n=20), Group 2: Kinesiotape and stabilization exercise (n=20), Group 3: Stabilization exercises (n=20), Group 4: Reflexology and stabilization exercises (n=20).
