Introduction: Pedicle screw placement in spinal surgery has evolved to incorporate increased use of technology for both preoperative planning and intraoperative guidance. In recent years, robotic guidance has been used to increase the precision, accuracy, and overall patient safety of spinal column fixation via screw placement. Within this context, the present study aims to quantify and classify complications of spinal robotic devices using a nationally representative database.

This is particularly pertinent in minimally invasive spine surgeries that rely on imaging and technologies for visualization and the ability to accomplish surgical goals through smaller surgical corridors. The ability to preoperatively plan and then place pedicle screws across a wide range of applications has reduced the difficulty of even complex surgeries that once may have been considered prohibitive for minimally invasive approaches.

Objective: Perform a systematic review to identify all reports directly comparing outcomes of lateral lumbar interbody fusion (LLIF) using static versus expandable interbody cages. Specifically focusing on periprocedural complications, intraoperative morbidity, and fusion outcomes.
Background: Cervical stenosis (CS) is the pathologic narrowing of the central canal of the cervical spine. It is often incidentally discovered. It is unclear whether pre-existing CS can lead to worse outcomes and higher incidences of post-traumatic spinal cord injury (SCI).

If thoracic herniation can produce angina-like pain, then it is important to consider whether pathology of the thoracolumbar spine, in general, can trigger false pain syndromes distinct from pseudoangina.
Objective: We seek to provide the most comprehensive study regarding the diagnosis and treatment of spinal conditions causing false pain syndromes.
Background: Tethered cord syndrome (TCS) is a rare neurological disorder characterized by longitudinal stretching on the distal end of the spinal cord. The condition commonly manifests in lumbosacral and lower-extremity pain and weakness, sensory disturbances, and incontinence. Traditionally, tethered cord release has been the first-line management for TCS, but retethering and complications such as cerebrospinal fluid leakage are commonly reported.

Single-position lateral surgery is a popular variation that places patients in the lateral decubitus position, allowing concomitant placement of lateral interbodies and posterior segmental instrumentation without the need for repositioning the patient. The addition of robotics to this technique can help to overcome ergonomic limitations of the placement of pedicle screws in the lateral decubitus position; however, its description in the literature is relatively lacking.

Surgical correction may involve the major and/or distally-located fractional curves (FCs). Correction of the FC has been increasingly recognized as key to ameliorating radicular pain localized to the FC levels.

A diagnosis of BRP is typically confirmed with the "ice-pack" test and evidence of cervical spine pathology using magnetic resonance imaging. Treatment options consist of application of ice, reduction in sun exposure, and topical capsaicin, antiepileptics, or tricyclic antidepressants.
View Article and Find Full Text PDF(1) The correction of adult spinal deformity (ASD) can require long, complex constructs with multiple rods which traverse important biomechanical levels to achieve multi-pelvic fixation. Minimally invasive (MIS) placement of these constructs has historically been difficult. Advanced technologies such as spinal robotics platforms can facilitate the design and placement of these constructs and further enable these surgical approaches in MIS deformity surgery.
View Article and Find Full Text PDFBackground: Adult spinal deformity (ASD) occurs from progressive anterior column collapse due to disc space desiccation, compression fractures, and autofusion across disc spaces. Anterior column realignment (ACR) is increasingly recognized as a powerful tool to address ASD by progressively lengthening the anterior column through the release of the anterior longitudinal ligament during lateral interbody approaches. Here, we describe the application of minimally invasive ACR through an oblique antepsoas corridor for deformity correction in a patient with adult degenerative scoliosis and significant sagittal imbalance.
View Article and Find Full Text PDFBackground/objective: The recent development of minimally invasive surgical techniques (MIS) has made possible the correction of adult spinal deformity (ASD) with less blood loss and shorter hospital stays. However, minimally invasive placement of pedicle screws at the proximal level of the construct can increase pseudarthrosis risk, leading to implant failure, kyphosis, and reoperations. We aggregate existing literature to describe pseudarthrosis rates at the proximal thoracic or thoracolumbar junction in MIS and subsequent reoperation rates.

With the introduction of robotics in spine surgery, surgeons can place pedicle screws with a high degree of accuracy and efficiency; moreover, the robot allows us to localize the disk space and perform endplate preparation accurately with minimal radiation. In this study, we discuss the potential synergistic benefits of integrating robotic-assisted spine surgery and singleposition prone lateral surgery.

This variation in anatomy exposes patients to additional surgical risks.
Methods: In order to shed light on surgical considerations reported for lumbar spine cases involving LSTV as described in the extant literature, we performed a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.
We present here a 58-year-old female patient with L4-5 spondylolisthesis, who underwent a minimally invasive L4-5 oblique lumbar interbody fusion (OLIF) with robot-assisted bilateral posterior instrumented fixation in a single lateral position (Mazor X Stealth Edition, Medtronic). There has been interest in detailed video-based descriptions of single-position surgery with lateral approach interbody fusions, either in the prone or lateral decubitus position.1-6 Particularly, the addition of robotics has been shown to help increase overall operating efficiency in the lateral position with reduced case times even with the increased up-front robot setup time.

Methods: A systematic review of the literature was performed through an electronic search of the PubMed, Scopus, and Web of Science databases. Human studies between 2012 and 2023 were included.
Background: Lumbosacral transitional vertebrae (LSTVs) are congenital anomalies that occur in the spinal segments of L5-S1. These vertebrae result from sacralization of the lowermost lumbar segment or lumbarization of the uppermost sacral segment. When the lowest lumbar vertebra fuses or forms a false joint with the sacrum (pseudoarticulation), it can cause pain and manifest clinically as Bertolotti syndrome.

As the envelope for endoscopic approaches continues to be pushed, a recurrence of interest in laparoscopic and/or endoscopic anterior approaches seems possible. Therefore, evaluating the current evidence base in regard to this approach is of much clinical relevance.

These gains have been achieved without increases in operative times, blood loss, or hospitalization duration. However, most work has been done in the degenerative population and little is known of the utility of robotic assistance when applied to spinal trauma.

Single-position surgery with lumbar interbody fusion in the lateral decubitus position with concomitant PSP has been associated with increased operative efficiency. What remains unclear is the accuracy of PSP with robotic guidance when compared with the more familiar prone patient positioning.

Interbody fusion is a workhorse technique in lumbar spine surgery that facilities indirect decompression, sagittal plane realignment, and successful bony fusion. The 2 most commonly employed cage materials are titanium (Ti) alloy and polyetheretherketone (PEEK). While Ti alloy implants have superior osteoinductive properties they more poorly match the biomechanical properties of cancellous bones.
