What does ALAN HILIBRAND research?

Dr. Hilibrand studies various factors influencing the outcomes of spine surgeries, including lumbar fusion and cervical decompression. His research encompasses the impact of opioid use disorder, diabetes, and depression on recovery from surgery, as well as the effectiveness of medications like dexamethasone. He also investigates trends in outpatient surgeries and disparities in access to robotic spine surgery, which can affect patient care and recovery.

Key findings

  • Older adults (ages 30-69) have significantly higher odds of opioid use disorder during cervical fusion, facing longer hospital stays (3.23 days vs. 2.47 days) and higher costs ($31,900 vs. $27,000).
  • Patients with high depressive levels before lumbar fusion are more likely to need revision surgery within two years (13.4% vs. 5.15%).
  • Revision lumbar fusion patients require much higher long-term opioid usage compared to first-time patients (1,550 mg vs. 497 mg over 2 years).
  • Patients treated at Level I trauma centers have a 34% lower risk of dying in the hospital from operative spine trauma compared to those at Level II centers.
  • Access to robotic spine surgery is significantly lower in rural areas compared to wealthier regions, with a 22% discrepancy.

Semaglutide use before single-level lumbar fusion associated with fewer readmissions and 90-day costs.

2025

Journal of craniovertebral junction & spine

Ng MK, Mastrokostas PG, Rodriguez AN, Razi A, Mastrokostas LE +10 more

Plain English
This study looked at how using a diabetes and obesity medication called semaglutide affects patients who have single-level lumbar fusion surgery, a common spine procedure. Researchers found that patients taking semaglutide had lower readmission rates after surgery (8.7% compared to 11.4%) and also faced lower healthcare costs within 90 days after the operation. This matters because it shows that semaglutide can help improve recovery outcomes for these patients without increasing the risk of complications. Who this helps: Patients undergoing lumbar fusion surgery.

Spine

Huang R, Dalton J, Eichbaum Y, Heard J, Ezeonu T +17 more

Plain English
This study looked at how metformin, a diabetes medication, affects recovery in diabetic patients who had spinal surgery. Researchers found that patients taking metformin needed fewer opioids for pain relief after surgery—31.8 mg versus 52.0 mg within the first 90 days—and reported better improvement in their physical health a year after surgery. This is important because it suggests metformin may help reduce pain medication use and improve recovery outcomes for these patients. Who this helps: Patients with diabetes undergoing spinal surgery.

Delayed yet Durable Functional Recovery Following Posterior Cervical Decompression and Fusion for Mild Degenerative Cervical Myelopathy.

2025

Spine

Baidya J, Ng M, Green WA, Baek G, Dalton J +16 more

Plain English
This study looked at how well patients recover after a specific spine surgery called posterior cervical decompression and fusion (PCDF) for a condition called mild degenerative cervical myelopathy (DCM). The researchers found that while patients with more severe DCM showed quicker functional improvements after surgery, by two years, about 42% of patients with mild DCM achieved significant recovery, which is similar to the rates in moderate and severe cases. This is important because it indicates that even patients with mild DCM can experience meaningful benefits from surgery, though it may take longer for those benefits to appear. Who this helps: This helps patients with mild DCM and their doctors make informed decisions about surgery.

Relationship Between Preoperative Pfirrmann Grading and Adjacent Segment Degeneration After Anterior Cervical Diskectomy and Fusion.

2025

The Journal of the American Academy of Orthopaedic Surgeons

Dalton JF, Oris RJ, Mathew J, McCurdy MA, Alexander T +20 more

Plain English
This study looked at how the condition of the discs next to the ones being operated on can impact recovery after neck surgery, specifically anterior cervical decompression and fusion. Researchers found that patients with higher degeneration grades in their adjacent discs (Pfirrmann grades III and IV) had a significant decrease in disk height two years after the surgery. This means that if a patient's disc health is poor before surgery, it can lead to more serious issues after surgery, though the rate of needing follow-up surgeries remains the same after five years. Who this helps: This information helps patients and doctors by providing insights on the importance of assessing disc health prior to neck surgery.

Plain English
The study looked at emergency department visits after lumbar fusion surgeries, comparing patients who had their first surgery (primary) to those who had revision surgeries (to fix problems from their first surgery). It found that 10.2% of revision patients visited the emergency department within 90 days post-surgery, compared to 6.86% of primary patients. Most patients visited the ER for pain, and while revision surgery increased the chance of an ER visit, it only raised the risk by 3.4%. Who this helps: This information is valuable for patients and doctors involved in lumbar fusion surgeries.
