Minimally invasive lateral interbody fusion for the treatment of degenerative disc disease, spondylolisthesis, or scoliosis is becoming increasingly popular. The approach at L4-5 carries highest risk nerve injury given proximity lumbar plexus and femoral nerve. authors present 3 cases that were aborted during because pervasive electromyography responses throughout space. Preoperative imaging characteristics psoas muscle anatomy in all are analyzed discussed. In cases, on axial views was...
Surgical site infection (SSI) in spinal surgery contributes to significant morbidity and healthcare resource utilization. Few studies have directly compared the rate of minimally invasive (MIS) SSI with open surgery.To investigate whether MIS techniques had a lower degenerative lumbar procedures as traditional techniques.A single-center, retrospective review prospectively collected database was queried from January 2013 2016 for adult patients who underwent decompression and/or instrumented...
Percutaneous pedicle screws are used to provide rigid internal fixation in minimally invasive spinal procedures and generally require the use of Kirchner wires (or K-wires) as a guide for screw insertion. K-wires can bend, break, advance, or pull out during steps preparation This lead increased fluoroscopic surgical times potentially cause neurological, vascular, visceral injury. The authors present their experience with novel "K-wireless" percutaneous system that eliminates inherent risks...
Posterior cervical fusion (PCF) is performed to treat myelopathy, radiculopathy, and/or deformity. Constructs ending at the cervicothoracic junction (CTJ) may lead higher rates of adjacent segment disease, and much debate exists regarding crossing CTJ due paucity data in literature.To determine whether extension PCF constructs across decreases incidence disease need for revision surgery.A single-center retrospective case series patients undergoing multilevel PCFs since 2011 with least 6-mo...
Study Design: Prospective evaluation of 10 patients undergoing minimally invasive lumbar interbody fusion for degenerative disk disease and radiculopathy. Objective: To assess the feasibility percutaneous transfacet screw fixation in lateral decubitus position after fusion. Summary Background Data: Lumbar is commonly performed treatment with associated radiculopathy due to foraminal stenosis or protrusion. Minimally techniques, such as fusion, have been developed achieve this while reducing...
Abstract BACKGROUND Smartphone applications (apps) in the health care arena are being increasingly developed with aim of benefiting both patients and their physicians. The delivery adequate instructions before after a procedure or surgery is paramount importance ensuring best possible outcome for patients. OBJECTIVE To demonstrate that app-based built-in reminders may improve patient understanding compliance contribute to reducing number cancellations postoperative complications...
Background: Smartphone applications (apps) are being increasingly utilized in the health care arena to improve patient and outcomes. Objective: To further demonstrate ability of a smartphone app compliance with preoperative instructions decrease number last-minute surgery cancellations. Methods: Patients undergoing spine were prospectively accrued. users compared non-app users. Patient adherence as well cancellations analyzed. Results: All 85 adhered according acknowledgements sent web...
Single-position lateral lumbar interbody fusion (SP-LLIF) has recently gained significant popularity due to increased operative efficiency, but it remains technically challenging. Robot-assisted percutaneous pedicle screw (RA-PPS) placement can facilitate in the position. The authors have reported their initial experience with SP-LLIF RA-PPS position, and they compared this accuracy that of prone
This retrospective analysis examines the local control and toxicity of five-fraction fiducial-free CyberKnife stereotactic body radiation therapy (SBRT) for single vertebral (VB) metastases. All patients had favorable performance status (ECOG 0-1), oligometastatic disease, no prior spine irradiation. A prescribed dose 30-35 Gy was delivered in five fractions to planning target volume (PTV) using with X-sight tracking. Suggested maximum spinal cord esophagus point doses were 30 40 Gy,...
Achieving durable local control while limiting normal tissue toxicity with definitive radiation therapy in the management of high-risk brain metastases remains a radiobiological challenge. The objective this study was to examine and 5-fraction stereotactic radiosurgical approach for treatment patients inoperable single NSCLC metastases. This retrospective analysis examines 20 who were deemed have "high-risk" High-risk tumors defined as those maximum diameter greater than 2 cm and/or located...
Synovial cysts of the lumbar spine result from degeneration facet capsule and often mimic symptoms commonly seen with herniated intervertebral discs. In symptomatic patients, prevalence synovial may be as high 10%. Although conservative management is possible, majority patients will require resection. Traditional procedures for cyst resection use an ipsilateral approach requiring partial or complete complex, possibly leading to further destabilization. A contralateral technique using...
OBJECTIVE Surgery for thoracolumbar deformity can lead to significant muscle injury, excessive blood loss, and severe postoperative pain. The aim of the following studies was determine feasibility minimally invasive posterior thoracic corpectomy osteotomy techniques in human cadavers select clinical cases. METHODS Human cadaveric specimens were procured Smith-Petersen pedicle subtraction using a approach. Post-procedural computed tomography used assess degree decompression extent bone...
<b>Objective</b> The last decade has seen significant advances in minimally invasive techniques for lumbar interbody fusion that have reduced approach-related morbidity. Percutaneous involves a posterior transforaminal approach to the disk space with minimal access port through Kambin triangle. This technique obviates need facetectomy or laminectomy required traditional approach. article describes surgical technique, potential advantages and limitations, representative case illustrations....
Study Design A cadaver study comparing 3 different minimally invasive approaches to the anterior thoracic spine. Objective To assess feasibility of corpectomy from a posterolateral approach and compare surgical results approaches. Summary Background Data Traditional spine are effective but associated with high rate operative morbidity. Methods Thoracic corpectomies were performed using modified tubular retractor starting at 3, 6, 9 cm off midline. Postoperative computed tomography scans...
<h3>ABSTRACT</h3> <h3>Background:</h3> Anterior cervical discectomy and fusion (ACDF) has conventionally been performed using an allograft cage with a plate-and-screw construct. Recently, standalone cages have gained popularity due to theorized decreases in operative time postoperative dysphagia. Few studies compared these outcomes. Here, we directly compare the outcomes of plated versus ACDF constructs. <h3>Methods:</h3> A single-center retrospective review patients undergoing after June...
