Spine surgery is entering a period of difficult trade-offs. Surgeons have more ways to preserve motion, operate less invasively and measure outcomes, but greater technical capability does not always translate into better care or lower costs.
From the growing scrutiny of spinal fusion to the financial consequences of new technology, long-standing assumptions about how spine care should be delivered are being challenged.
Here are seven debates shaping the specialty, according to recent Becker’s reporting.
1. Spinal fusion vs. motion preservation: As artificial disc replacement and minimally invasive techniques advance, surgeons are reconsidering when spinal fusion is necessary and when preserving motion may offer a better long-term outcome.
Ramin Raiszadeh, MD, of San Diego Spine and Brain Institute, has made artificial disc replacement his preferred approach for appropriately selected patients. But other surgeons caution that avoiding fusion should not become an objective in itself, particularly when instability or other structural conditions require it.
“To me, a fusion is sort of the last resort,” Farah Musharbash, MD, a spine surgeon at Atlantic Brain and Spine in Morristown, N.J., told Becker’s. “But many times, it’s the right thing to do.”
The debate is shifting from whether surgeons can avoid fusion to whether motion-preserving alternatives can reliably address the underlying pathology without creating additional problems.
2. Surgical intervention vs. overtreatment: The ability to perform increasingly complex spinal reconstructions has raised questions about whether some patients are receiving more surgery than they need.
Vijay Yanamadala, MD, a neurosurgeon who has studied unnecessary spine surgery, has argued that the specialty needs stronger evidence to distinguish appropriate operations from potentially avoidable procedures.
In a commentary published by Becker’s, he emphasized the consequences of choosing the wrong intervention.
“The right operation, in the right patient, at the right time, gives people their lives back. The wrong one takes something from them that we cannot return,” Dr. Yanamadala wrote. The tension extends beyond clinical judgment. Reimbursement incentives, patient expectations and inconsistent surgical recommendations can complicate decisions about when to operate and how extensively.
3. Robotics and navigation vs. clinical value: Robotics, navigation and augmented reality are expanding what spine surgeons can accomplish, but their growing adoption is raising questions about cost, necessity and long-term clinical benefits.
Robert Hirschl, MD, a neurosurgeon at Orlando (Fla.) Health Neuroscience Institute, has questioned the use of expensive technologies for relatively straightforward procedures when their advantages remain uncertain.
“I have seen surgeons use robotics and augmented-reality goggles for straightforward, single-level [transforaminal lumbar interbody fusions], adding complexity and expense to cases that may not require it,” Dr. Hirschl told Becker’s.
He supports innovation but believes new systems should demonstrate measurable improvements in safety, outcomes, efficiency or costs. For health systems investing heavily in surgical technology, the debate increasingly centers on whether technical improvements justify the financial and operational burden.
4. Payer restrictions vs. clinical judgment: Prior authorization remains a major point of friction between spine surgeons and insurers, particularly when physicians believe delays or denials interfere with medically necessary treatment.
Payers use authorization requirements to manage utilization and spending. Surgeons, however, argue that those decisions can create additional administrative expenses, delay recovery and shift costs elsewhere in the healthcare system.
Kern Singh, MD, and Daniel Park, MD, of Chicago-based Rush University Medical Center, were among the authors of an Orthopaedic Forum paper examining the broader consequences of surgical denials.
“Delaying or denying indicated surgery does not reduce cost; it simply redistributes it,” the authors wrote. The dispute raises a fundamental question about whether restricting access to procedures ultimately reduces healthcare spending or simply transfers the financial burden to patients, physicians and employers.
5. Radiographic success vs. patient recovery: A spine operation can appear successful on imaging while leaving unanswered questions about whether the patient is functioning better.
Corinna Zygourakis, MD, a neurosurgeon and associate professor at Stanford (Calif.) University School of Medicine, is studying whether wearable technology can help close that gap.
Through her SpineTrack clinical trial, researchers are using Apple Watches to collect activity data before and after elective spine surgery, examining whether objective measurements can complement traditional patient-reported outcomes.
“Perfect imaging does not always equate to a happy patient,” Dr. Zygourakis told Becker’s.
Wearable data has not yet been shown to provide a superior assessment of recovery, but the research reflects a broader reconsideration of how the specialty defines successful surgery.
6. Surgical innovation vs. financial sustainability: As reimbursement pressures intensify and more spine procedures move into ASCs, surgeons are questioning whether hospitals understand the full cost of delivering surgical care.
Ahilan Sivaganesan, MD, director of minimally invasive spine surgery at Penn Medicine in Philadelphia, is studying expenses that traditional accounting may overlook, including instrument sterilization, transportation, equipment handling and personnel.
He describes those behind-the-scenes operations as an “invisible factory” supporting every procedure.
“In the past, hospitals could afford not to know the true cost of this invisible factory because their margins were good enough,” Dr. Sivaganesan told Becker’s. “But I think that’s going away.”
His research could challenge assumptions about the economics of reusable instruments, single-use equipment and expensive surgical technologies. The question is no longer simply whether a device improves surgery, but whether its benefits justify the infrastructure required to use it.
7. More surgical data vs. better decision-making: Spine surgeons can measure alignment, analyze imaging and predict certain procedural risks with increasing precision. Yet determining which patients will meaningfully benefit from surgery remains a significant challenge.
Alpesh Patel, MD, an orthopedic spine surgeon and co-director of the Northwestern Center for Spine Health at Chicago-based Northwestern Medicine, believes the specialty has more work to do in predicting individual outcomes.
“We’re probably not as good as we think we are, across the profession, at truly predicting who’s going to improve and not improve,” Dr. Patel told Becker’s.
Even when surgery produces measurable improvement, patients may not experience the degree of relief or functional recovery they expected.
As AI and predictive analytics become more sophisticated, surgeons face a critical question: Will additional data meaningfully improve patient selection and counseling, or simply make existing decisions more technologically complex?
At the Becker’s 32nd Annual Meeting: The Business and Operations of ASCs, taking place October 29-31 in Chicago, ASC leaders, surgeons and healthcare executives will explore strategies to drive growth, enhance operational performance, navigate reimbursement challenges and prepare for the future of ambulatory surgery.
