Active clinical trials for "Spondylolisthesis"

The purpose of this study is to evaluate a Zhineng Qigong intervention for patients with chronic low back pain and/or leg pain, and to test feasibility aspects.

The purpose of the study is to determine the proper use of lower back screws and rods (instrumentation) and bony fusion in subjects with one level of degenerative spinal narrowing (stenosis) compressing nerves to the legs with one spinal bone slipping forward on another (spondylolisthesis). There are two types of operations that surgeons perform for this problem. Some spinal surgeons remove some bone in the back (laminectomy) to decompress the nerves. Other surgeons perform a laminectomy (decompression) as above, but feel that it is also important to strengthen the back by placing screws and rods into the spine and adding more bone to obtain a new bridge of bone away from the nerves (decompression with instrumented fusion). This study aims to test the hypothesis that adding instrumented fusion to a decompression for this spinal problem will improve long term patient outcomes.

This is a single-arm post-market study in patients requiring lumbar fusion using allograft interbody spacer in conjunction with map3® Cellular Allogeneic Bone Graft in patients with degenerative disc disease (DDD). This cohort study will enroll 80 patients total at up to 10 sites. After subjects have signed an informed consent, the baseline visit and examinations will be completed. Patients will be evaluated at 6 weeks, 3 months, 6 months, 12 months, and 24 month visit after surgery.

This study assesses clinical outcomes following the use of the MvIGS spine navigation system for treatment of spinal stenosis and degenerative spondylolisthesis of the lumbar spine in adults. There will be separate study arms for cases utilizing the three-dimensional (3D) MvIGS spine navigation system and cases that utilize conventional two-dimensional (2D) fluoroscopy.

The trial was designed to demonstrate the comparability of the overall success rate in the OP-1 Putty treatment group to the autograft treatment group.

This study randomizes degenerative spondylolisthesis and/or degenerative disc patients into two groups: one to receive a new ceramic implant and a control group with a more traditional PEEK plastic implant. The procedure uses a single oblique cage in each group. The study will measure and compare pain and disability improvement with the two implanted devices over a period of two years. The fusion status will also be judged with plane x-rays and one CT scan.

Background: Different methods for lumbar pedicular screw insertion have been advocated, however each technique has its cons and pros. Due to limited resources for O-Arm and navigation in our locality, the investigator was enforced to use the surgical skills to minimize the need for such advanced modalities. Aim of the study: Is to clarify the benefits of the use of free hand technique using direct visualization of the pedicles and disc space as the only guide for pedicular screw insertion using postoperative CT for evaluation of the accuracy of pedicle screw insertion. Patients and methods: One hundred and forty four screws were inserted in 32 patients using direct pedicle visualization and disc space orientation as a single intraoperative reference guide. The study was conducted in Zagazig University Hospitals from May, 2014 to June, 2015. CT was done for all patients as a direct postoperative evaluation tool.

This was a retrospective study.PI and LL greatly influence IS and its progression. However, relationships between the spinopelvic parameters and clinical symptoms of patients with IS were not fully investigated in previous studies. Investigators hypothesized that spinopelvic parameters might be related to the clinical symptoms of IS patients. Therefore, the purpose of the present study was to investigate whether differences in spinopelvic parameters, especially spinopelvic alignment, may be associated with the clinical symptoms of low-grade IS patients.

The purpose of this study is to collect information about how patients feel when doctors manage their pain after lumbar spine surgery using a combination of EXPAREL® and bupivacaine injected into the lumbar spine at the end of surgery, compared to the patients that doctors use only EXPAREL® or bupivacaine to manage their pain. This information will help doctors determine which approach works best for patients who will receive surgery in their lumbar spine in the future.

Appropriate fluid management is an important part of anesthesia in patients undergoing surgery, and several dynamic indices have been suggested to have high predictability for fluid responsiveness in patients receiving mechanical ventilation. Among various surgical positions, the prone position is known to cause unique physiologic and hemodynamic changes and affect the predictability and cut-off values of dynamic indices for fluid responsiveness. A previous study reported that pulse pressure variation (PPV) and corrected flow time were able to predict fluid responsiveness with relatively high accuracy in patients undergoing spine surgery in the prone position using a Wilson frame. However, the Jackson frame is known to have less effects on the cardiovascular system compared to the Wilson frame, and therefore may be physiologically more appropriate in patients undergoing surgery in the prone position. The pleth variability index (PVI) is a dynamic index that can be monitored non-invasively in patients under mechanical ventilation. The present study aims evaluate the validity of PPV and pleth variability index (PVI) as predictors of fluid responsiveness in the supine and prone positions in patients undergoing posterior lumbar spinal fusion using the Jackson table.
