Filter by:The objective of this study is to evaluate the impact of VRSim 3.0 on power wheelchair (PWC) driving skills and to obtain qualitative feedback from users on the design of the virtual reality (VR) simulator to inform device development.
Cervical myelopathy (CM), a chronically compressive spinal cord lesion, is the most common cause of non-traumatic paraparesis/quadriparesis among the elderly. Hong Kong is facing a heavy social economic burden from CM with the rapidly aging population. Surgical decompression is considered as the mainstay of the treatment for CM patients to relieve their symptoms and signs. Yet the surgical outcome is not always satisfactory. There is a pressing need for understanding the exact mechanism of surgical decompression on the recovery of myelopathic cord in order to improve the prognosis of CM patients in near future.This project will evaluate neuronal activities and axon regeneration by longitudinally monitoring at time zero, 3 and 6 month after the surgery in CM patients using UTE, BOLD-fMRI and DTI, and to investigate the relationship of preoperative neuronal activities of myelopathic cord with axon regeneration.
The main objectives of this study are to evaluate the benefits of back bracing in the symptomatic management of patients with CLBP due to degenerative lumbar disc disease. The plan is to study patients with uncomplicated CLBP without symptoms of radiculopathy or neurogenic claudication. The secondary objectives of the study are to evaluate if a back brace provides any additive benefit to usual care consisting of exercise and patient education in patients with CLBP due to degenerative disc disease. Specific Aim 1. To evaluate the effectiveness of back brace to improve pain and patient-reported functional measures in patients with uncomplicated CLBP due to degenerative disc and degenerative joint disease without associated symptoms of neurogenic claudication or lumbosacral radiculopathy. Hypothesis 1. Back brace in addition to usual care will provide statistically significant improvement in pain and functional measures compared to usual care alone. Specific Aim 2. To evaluate the adherence to back brace wear instructions in patients with uncomplicated CLBP due to degenerative disc and degenerative joint disease without associated symptoms of neurogenic claudication or lumbosacral radiculopathy Hypothesis 2. Patients with CLBP, due to degenerative disc and degenerative joint disease without associated symptoms of neurogenic claudication or lumbosacral radiculopathy, who are prescribed a back brace, will demonstrate clinically acceptable rates of adherence to brace wear instructions.
This study compares the intraoperative opioid free anesthesia approach in multilevel spine posterior instrumentation surgery to a conventional opioid-based anesthesia. Half of participants will receive opioid free anesthesia with dexmedetomidine, lidocaine and ketamine while the other half will receive opioid based anesthesia with fentanyl, remi-fentanyl and ketamine
The five-repetition sit-to-stand test has been validated and is used primarily in pulmonary medicine and cardiology, and has recently been shown to be a useful tool for the objective assessment of functional impairment in patients with degenerative diseases of the lumbar spine. The goal of this study is to assess the possibility of supervised and unsupervised at-home-assessment. Validation of at-home-assessment would allow the 5R-STS to be easily used as a follow-up tool in clinical trials, for example.
The purpose of this study was to evaluate the efficacy, in preventing Spinal Surgical Infection, of intraoperative pulsatile irrigation with a 2000-ml saline solution of PVP-Iodine in a group of patients undergoing complex spine surgery with a posterior approach. To confirm and better assess the efficacy of intraoperative irrigation on the infection rate in spinal surgery, specimens for bacterial culture were harvested by swabs from muscular tissue before and after irrigation of the wounds
In spine surgery postoperative pain can often be severe and difficult to treat.With the use of ultrasound, the performance of plane blocks and other techniques like root blocks, facet infiltration have become possible without the use of either unreliable " pop-techniques" or the use of x-ray.The erector spinae block was recently described as a safe and simple and safe technique for neuropathic pain and acute post surgical pain, with effect on the dorsal rami of the spinal nerves and with promising results. In this observational pilot study we want to test the influence of these to blocks on the postoperative pain and opioid consumption after spine fusion.
The investigators will do the Goal directed fluid therapy by protocolized fluid management in the experimental group, using PPV to guide the fluid administration, compare with standard fluid management in patients undergoing complex spine surgery.
Subclinical infection of the intervertebral disc after lumbar disc herniation surgery has been correlated to chronic low back pain and vertebral endplate changes. The most commonly reported agent is Propionibacterium acnes. However, the real incidence is unclear, as it has been reported in some series ranging from 3.7% to 46%. Recently, a systematic review concluded that there is a relationship between P. acnes and endplate changes, but, there are so far no studies to verify whether the reported presence of that pathogen in the intervertebral discs is due to local infection or whether intraoperative contamination occurred during the collection of samples. Thus, the main objective of this study is to estimate the incidence of subclinical infection in patients surgically treated for lumbar disc herniation. To this end, a prospective cohort study will be conducted with a minimum of 95 patients between 18 and 65 years of age who have been submitted to surgery after failure of conservative treatment. The extruded disc will be removed and cultured for bacterial identification. As controls, the ligamentum flavum and the multifidus muscle, taken respectively before and after removal of the herniated fragment will also be cultured. Patients will be followed-up for a year and MRI will be done at the end of this period.
Ultrasound guided thoracolumbar interfascial plane (TLIP) block was first described in 2015 by Hand et al. TLIP block involves injection of local anesthetics between multifidus and longissimus muscles at the third lumbar vertebra level and can block the dorsal rami of thoracolumbar nerves. In new approach differently, the investigators made the injection between longissimus and iliocostalis muscles with a 15 degree angle from medial to lateral. The aim of this study is to determine effectiveness of ultrasound guided thoracolumbar interfascial plane (TLIP) block in patients undergoing spinal surgery.
