Transdural retrieval of retropulsed transforaminal lumbar interbody fusion cages.

Transforaminal lumbar interbody fusions (TLIFs) are performed for various lumbar spine pathologies. Posterior migration of an interbody cage is a complication that may result in neurologic injury and require reoperation. Sparse information exists regarding the safety and efficacy of a transdural approach for cage retrieval. We describe a surgical technique, in which centrally retropulsed cages were safely retrieved transdurally. A patient with prior L3-S1 posterior lumbar fusion and L4-S1 TLIFs presented with radiculopathy and weakness in dorsiflexion. Imaging revealed posterior central migration of TLIF cages causing compression of the traversing L5 nerve root. Cages were removed transdurally; the correction was performed with an all-posterior T10-pelvis fusion. Aside from temporary weakness in right-sided dorsiflexion, the patient experienced complete resolution in their radiculopathy and strength returned to its presurgical state by 3 months. The transdural approach for interbody removal can be safely performed and should be a tool in the spine surgeon's armamentarium.

Correction of cervical kyphoscoliosis, bisected spinal cord, and vertebral artery to epidural vein fistula in neurofibromatosis type 1.

Neurofibromatosis-1 (NF1) presents complex challenges due to its multisystemic effects, including kyphoscoliosis, dural ectasia, and arteriovenous fistulas (AVF). We present a case of a 31-year-old male with NF1 exhibiting severe cervical kyphoscoliosis, dural ectasia, a bisected cervical cord, and an arteriovenous fistula, highlighting the intricacies of managing such intricate cases. Rapid weakening in the patient's right arm and leg prompted imaging revealing severe cervical kyphotic deformity and a dural fold dividing the spinal cord. Surgical intervention addressed a high-flow arteriovenous fistula involving the right vertebral artery and an epidural vein, necessitating sacrifice of the artery. Posterior fusion and laminectomy were performed, resulting in stable neurological status postoperatively and significant improvement in sensory loss and weakness at three months. This case underscores the importance of a tailored posterior-only approach, involving dural fold release, to allow the spinal cord to relocate to a less tense position, thus demonstrating effective decompression in complex NF1 cases with concurrent kyphotic deformity and vertebral artery AVF.

Utilization of Locum Tenens in Neurosurgery.

INTRODUCTION: Despite its rising popularity, little has been described about locum tenens employment (locums) in neurosurgery. This study provides the first nationwide overview of the locums neurosurgery experience. METHODS: An anonymous online survey examined practice characteristics of respondents, extent of and satisfaction with locums, motivations for pursuing locums, case volumes, agencies used, compensation, and positive/negative aspects of experiences. Responses were collected between November 2020 and February 2021. RESULTS: Response rate for the 1852 neurosurgeons who opened the survey request was 4.9%; 36 of 91 respondents had previously worked locums and were commonly motivated by compensation or transitioning to new jobs or retirement. In our response group, 92% of locums respondents had taken more than one position and 47% had taken more than 10. Neurosurgeons performing <200 cases/year were significantly more likely to have also worked locums than those performing >200 cases/year (41.6% locums, 12.7% non-locums, P = 0.001). Responses showed that 69% of locums respondents earned $2000-$2999/day and 16% earned >$3500/day. Nearly 78% of locums respondents were satisfied with their experience(s) and 86% would take another future locums position. Being in practice for >15 years was significantly associated with satisfaction with locums (P = 0.03). Reported flaws included unfamiliarity with hospitals, limited continuity of care, credentialing burdens, and inadequate travel compensation. CONCLUSIONS: Locums is utilized by neurosurgeons across multiple practice types and may serve to complement workloads or "fill in gaps" between longer-term employment. Overall, locums neurosurgeons are well compensated, and the majority are satisfied with their experience(s). Inevitably, flaws still exist with locums employment, which may be the focus of organized efforts aiming to improve the experience.

Is spinopelvic mismatch associated with increased disability at 2 years following short-segment lumbar fusions?

OBJECTIVE: This study aimed to investigate the impact of pelvic incidence (PI) and lumbar lordosis (LL) matching on health-related quality of life (HRQOL) outcomes in patients undergoing one- or two-level lumbar fusions for degenerative pathology. The study also examined changes in alignment and HRQOL over a 24-month follow-up period. METHODS: A retrospective cohort study used data from a multicenter, prospectively collected database. Radiographic parameters were measured preoperatively and at 3-month and 24-month postoperative time points. Patients were categorized as having alignment (PI-LL ≤ 10°) or malalignment (PI-LL > 10°) at all time points. The Oswestry Disability Index scores were collected at the same time points. Statistical analyses assessed differences in HRQOL scores and radiographic parameters between the aligned and malaligned groups. RESULTS: Seventy-six patients were included. Both the aligned and malaligned groups showed improved HRQOL scores after surgery, but patients with proper alignment (PI-LL ≤ 10°) had significantly better HRQOL scores at the 24-month follow-up. Alignment remained stable from 3 months to 24 months postoperatively, with minimal movement between the aligned and malaligned groups. CONCLUSIONS: Proper PI-LL matching in one- and two-level lumbar fusions for degenerative pathology leads to improved HRQOL outcomes at the 24-month follow-up. Patients with maintained proper alignment after surgery experience continued improvement in disability levels. Surgeons should consider longer follow-up for patients who do not achieve proper alignment initially, as 24 months is crucial for assessing the consequences of malalignment in short-segment lumbar fusions.

Monthly multidisciplinary complex spine conference: a cost-analysis utilizing time-driven activity-based costing.

PURPOSE: To understand costs and provide an initial framework associated with conference implementation as it pertains to complication prevention. METHODS: Team members' time spent on conference preparation, presentation, and follow-up tasks was recorded and averaged to determine the time required to prepare and present one patient. Using 2022 hourly wage rates based on our urban hospital setting, wage values were calculated for each personnel type and applied to their time spent. The total cost of the conference was annualized and calculated from the time spent in the three phases of the conference multiplied by the wage rate. Published data on complication rates and associated costs before and after conference implementation were used to calculate total cost reduction. RESULTS: With 3 active spine surgeons and 108 patients per year, the total time investment was 104.04 min per patient, costing $21,791 annually. Total RN equivalent value per patient was 5.25 for all three phases. Using a historical model, this multidisciplinary approach for adult spinal deformity reduced complications by 51% at 30 days, resulting in cost savings of $418,518 per year. Thus, the model demonstrates that implementation of this approach resulted in a potential total savings of $396,726/year. CONCLUSION: Implementing a cost-saving tool for managing complex spinal disorders is a responsibility of the spine team, who should lead a multidisciplinary conference. The combination of TDABC and lean methodology can effectively demonstrate the variable costs associated with this multidisciplinary effort and models provide evidence of potential cost-savings when applied to a multidisciplinary adult spinal deformity conference. These findings should encourage clinicians and administrators to allocate resources to improve patient care by reducing complications and costs.

"There's got to be a better way": Global Perspectives of Medicolegal Environment and Neurosurgical Socioeconomics.

Neurosurgery is considered to have one of the greatest risks of medical malpractice claims. However, medicolegal issues in neurosurgery are often disregarded and underrated worldwide. Medical errors in the neurosurgical field can be attributed to multiple factors, including highly morbid pathologies, the technical difficulty of neurosurgical procedures, and the involvement and interaction of a multidisciplinary team in the care of neurosurgical patients. Health care providers worldwide are at risk of lawsuits, sometimes even when no deviation from the standard of care had occurred in a given case. Often, governments use additional tactics to decrease the burden on compensators and extrajudicial institutions and to decrease the court's flow of irrational litigation. Continuous amendments to health care acts and newer reforms to address these issues have materialized worldwide. In the present narrative review, we have reviewed the global perspectives of medicolegal issues, with a focus on neurosurgical discipline.

The Medical Legal Environment in Neurosurgery: An Informative Overview of the Stages of Litigation and Distinct Challenges.

Medical malpractice litigation is something that every neurosurgeon encounters in his or her career and causes significant strife to amateur physicians attempting to navigate the medicolegal process. Neurosurgery in particular is one of the highest risk specialties for litigation. This calls to order the importance of a clear understanding of the medicolegal proceedings that may follow after a complaint has been filed. This report describes the steps to be taken by the physician in the instance that litigation is expected or considered a possibility. We describe the elements that comprise a medical malpractice claim, details of the lawsuit process including hospital peer review and expert witness selection, and how to communicate appropriately with the patients and their families in an empathetic way. It is imperative to gain an appropriate understanding of the entirety of the malpractice claim process to ease the anxiety of litigation for the physician and decrease the amount of avoidable complications.

Advocacy to Government and Stakeholders.

Participation in the health care and government advocacy arena may represent new and challenging perspectives for the traditional neurosurgeon. However, those with a strong understanding of the laws, rules, regulations, and fiscal allocation process can directly influence the practice of neurosurgery in the United States. We seek to shine light on the black box of how health care laws are passed, the influence and techniques of lobbying, and the role and rules surrounding political action committees. This practical review of health care advocacy is supplemented by a blueprint for engagement in the political arena for the practicing neurosurgeon.

Status of current medicolegal reform in the United States: a neurosurgical perspective.

OBJECTIVE: There are approximately 85,000 lawsuits filed against medical practitioners every year in the US. Among these lawsuits, neurosurgery has been identified as a "high-risk specialty" with exceptional chance of having medical malpractice suits filed. Major issues affecting the overall medicolegal environment include tort reform, the formation of medical review panels, the increasing practice of defensive medicine, and the rising costs of medical insurance. In this study, the authors provide a concise update of the current medicolegal environments of the 50 states and provide a general guide to favorable and unfavorable states in which to practice neurosurgery. METHODS: Data were acquired related to state-by-state medical review panel status, noneconomic damage caps, economic damage caps, and civil suit filing fees. States were placed into 5 categories based on the status of their current medicolegal environment. RESULTS: Of the 50 states in the US, 18 have established a medical review panel process. Fifteen states have a mandatory medical review process, whereas 3 states rely on a voluntary process. Thirty-five states have tort reform and have placed a cap on noneconomic damages. These caps range from $250,000 to $2,350,000, with the median cap of $465,900. Only 8 states have placed a cap on total economic damages. These caps range from $500,000 to $2,350,000, with the median cap of $1,050,000. All states have a filing fee for a medical malpractice lawsuit. These costs range from $37 to $884, with the median cost for filing of $335. CONCLUSIONS: Medicolegal healthcare reform will continue to play a vital role in physicians' lives. It will dictate if physicians may practice proactively or be forced to act defensively. With medicolegal reform varying greatly among states, it will ultimately dictate if physicians move into or away from certain states and thus guide the availability of healthcare services. A desirable legal system for neurosurgeons, including caps on economic and noneconomic damages and availability of medical review panels, can lead to safer practice.

Contract Negotiation for Neurosurgeons: A Practical Guide.

Contract negotiation is a reality in the career of any neurosurgeon. However, little formal training exists for physicians - including neurosurgeons - on potential techniques and strategies for conducting meaningful contract negotiation. Increasing numbers of neurosurgeons seek hospital employment for which an employment contract will be provided. During contract negotiation, it is likely that a young neurosurgeon will be in discussion with an experienced negotiator acting on behalf of a hospital, practice, or department. Understanding and adapting to this imbalance in experience and using basic negotiating techniques as a means of approaching and resolving key contract issues is critical for the neurosurgeon to maximize his or her value in the course of contract negotiation. Even without formal training in negotiation in residency, negotiation skills can be taught, practiced, and improved. In affiliation with the Medical Director's Ad-Hoc Representational Section of Council of State Neurosurgical Societies (CSNS) this article is intended to serve as a practical guide for contract negotiation. Contract basics, negotiation terms, strategies, unique neurosurgical issues, and value creation are explored.

Analysis of Factors and Conditions Influencing Military Neurosurgery Recruitment and Retention.

INTRODUCTION: The Defense Health Agency has shifted focus of military medicine to operational readiness. As such, neurosurgery remains a critical wartime specialty. We investigate the factors impacting recruitment and retention of military neurosurgeons. METHODS: Survey of military neurosurgeons was performed via the American Association of Neurological Surgeons/Congress of Neurological Surgeons Joint Committee of Military Neurosurgeons and the Council of State Neurosurgical Societies. Retention and recruitment were queried. RESULTS: 93/119 (78.2%) current or previously affiliated military neurosurgeons would recommend service as a military neurosurgeon to a colleague. Those who felt a sense of patriotism were 4.3 times more likely to recommend military service (P = 0.027, CI 1.19-16.82). Those who developed a sense of camaraderie showed a trend to recommending military neurosurgery (P = 0.058, CI 0.95-9.78). Those with a current military obligation were.28 times (P = 0.02, CI 0.09-0.85) as likely to recommend service. Military physicians who felt a need for reform to increase salary were 2.5 times less likely to be retained. DISCUSSION: Service in the US military is a positive experience with camaraderie, patriotism, and unique military experiences predictive of recruitment. Meanwhile, focus on pay discrepancy can result in lost retention. These factors should be explored regarding recruitment and retention of military neurosurgeons.

The Medical Review Panel in Louisiana Neurosurgery and Beyond.

For the past several decades, medical malpractice claims in the state of Louisiana have been screened by a pretrial medical review panel (MRP). Composed of 3 physicians and 1 attorney, these panels are a method of filtering nonmeritorious lawsuits while expediting creditable claims. Currently, 14 jurisdictions in the United States require medical liability/malpractice cases be heard by an MRP or screening panel prior to trial. In this article, we review the MRP process in Louisiana and compare it to those in other states. Data are presented for the past 10 yr of malpractice claims in Louisiana with an emphasis on the neurosurgery specialty. Finally, the benefits and challenges of pretrial screening panels are discussed.

Orbitopterional Craniotomy Resection of Pediatric Suprasellar Craniopharyngioma.

The orbitopterional approach provides an excellent combination of basal access and suprasellar access. This approach also allows for less brain retraction when resecting larger suprasellar tumors that are more superiorly projecting due to a more frontal and inferior trajectory. In this operative video, the authors thoroughly detail an orbitopterional craniotomy utilizing a one-piece modified orbitozygomatic technique. This technique involves opening the craniotomy through a standard pterional incision. The craniotomy is performed using the standard three burr holes of a pterional approach; however, the osteotomy is extended anteriorly through the frontal process of the zygomatic bone as well as through the supraorbital rim. In this operative video atlas, the authors illustrate the operative anatomy, as well as surgical strategy and techniques to resect a large suprasellar craniopharyngioma in a 4-year-old male. Other reasonable approach options for a lesion of this size would include a standard pterional approach, a supraorbital approach, or expanded endoscopic transsphenoidal approach. The lesion was quite high and thus, the supraorbital approach may confine access to the superior portion of the tumor. While recognizing that some groups may have chosen the endoscopic expanded transsphenoidal approach for this lesion, the authors describe more confidence in achieving the goal of a safe and maximal resection with the orbitopterional approach.

Multiple supratentorial subependymomas causing obstructive hydrocephalus.

INTRODUCTION: Subependymomas are benign intraventricular tumours that most often occur asymptomatically and are found incidentally on autopsy. Symptomatic examples requiring surgical intervention are exceedingly rare. CASE PRESENTATION: A 55-year-old man with no history of neurological symptoms presented with multiple episodes of loss of consciousness and increasing headaches. MRI revealed a lobulated intraventricular mass centred at the right Foramen of Monro. Obstructive hydrocephalus with localised midline shift and a second lesion were noted. Right frontal craniotomy with total removal via transcortical resection was performed. DISCUSSION: Symptomatic subependymomas generally present with signs of hydrocephalus due to obstruction of cerebrospinal fluid pathways. There is only one other reported case of multifocal subependymomas in a symptomatic patient. An example of multiple supratentorial subependymomas causing obstructive hydrocephalus has not been previously reported. CONCLUSIONS: Multiple subependymomas are rare. Judicious surgical management with full excision led to symptomatic improvement in our patient.
