Prospective Study of ProteiOS in Lumbar Interbody Fusion (TLIF)

This is a prospective, multicenter, randomized, controlled study evaluating Influx™ ProteiOS®, an allograft-derived growth factor product, in transforaminal lumbar interbody fusion (TLIF). Participants undergoing 1- to 2-level TLIF (L2-S1) are randomized 2:1 to receive ProteiOS or a control graft (local bone with optional cancellous chip augmentation, no ProteiOS). The primary objective is to determine whether the 12-month interbody fusion rate (assessed by CT using the Brantigan-Steffee-Fraser classification) with ProteiOS is non-inferior to control, using a 5-percentage-point non-inferiority margin. Patient-reported outcomes (ODI, VAS, EQ-5D-5L), safety, and healthcare utilization are also assessed. A separate exploratory cohort at one study site will evaluate the same outcomes in participants undergoing anterior lumbar interbody fusion (ALIF) with or without ProteiOS, without formal hypothesis testing.

NSAIDS Following Elective Lumbar Spine Fusion

This study will compare two common approaches to pain control after lumbar spinal fusion surgery. Participants will be randomly assigned to receive either standard pain medication alone or standard pain medication plus a short course of nonsteroidal anti-inflammatory drugs (NSAIDs), including intravenous ketorolac while in the hospital and oral naproxen for one week after discharge. The main goal is to determine whether taking NSAIDs after surgery affects how well the spine heals by increasing the chance of needing another surgery because the bones did not fuse properly within 2 years. The study will also evaluate pain medication use, recovery, hospital readmissions, complications, physical therapy progress, patient-reported pain and function, and overall healing. The results will help determine whether NSAIDs can be used safely as part of pain management after lumbar spinal fusion surgery while potentially reducing the need for opioid medications.
