Dr. Roger Härtl, Neurosurgical Director, Och Spine at NewYork-Presbyterian/Weill Cornell Medical Center and a leading expert in minimally invasive and complex spine surgery, has contributed to two newly published studies that offer important insights into the use of expandable interbody cages in spinal fusion procedures. Coverage of both studies appeared in Becker’s Spine Review, underscoring their significance within the field.
Safety and Effectiveness in Cervical Fusion
A recent publication examining the use of expandable titanium cages in anterior cervical discectomy and fusion (ACDF) found that these implants are safe and effective for restoring cervical alignment and providing stable reconstruction. Because the device can be expanded during surgery, it allows surgeons to adjust height and positioning to meet the specific needs of each patient. Dr. Härtl noted that the technology supports more personalized and precise cervical spine care.
“Our goal is to use technologies that genuinely improve alignment and long-term stability for our patients,” Dr. Härtl explains. These studies help clarify where expandable cages offer clear benefits and where careful selection is essential. Evidence like this allows us to make more precise decisions and deliver care that fits each patient’s needs.”
Patient-Specific Use in TLIF
A second study evaluating expandable cages in transforaminal lumbar interbody fusion (TLIF) highlights that these devices are not a one-size-fits-all solution. Outcomes depend on several factors including implant design, degree of expansion and overall alignment goals. This reinforces the importance of careful patient selection and surgical planning, an approach central to Dr. Härtl’s commitment to evidence-based individualized treatment.
Advancing Personalized Spine Care
Together, these publications reflect Dr. Härtl’s ongoing effort to advance spinal surgery through innovation, research and patient-focused care. His work continues to guide best practices in minimally invasive techniques, surgical navigation and optimized spine reconstruction at Weill Cornell Medicine.
