SpineSurgeryErrors.

Spine surgery operates in a region where external landmarks do not reveal the internal anatomy — a surgeon cannot tell by looking at the back which level is which. Internal orientation requires intraoperative imaging correlated with pre-operative imaging showing the pathology. When that correlation fails, the wrong level gets operated on.

Common clinical scenarios:

• Lumbar discectomy at the wrong level. The most common reported scenario. Pre-operative MRI showed disc herniation at L4-L5; surgeon operated on L3-L4 or L5-S1.
• Cervical decompression at the wrong level. Cervical anatomy is more technically demanding to localize because the thoracic cage provides fewer counting landmarks.
• Fusion at the wrong level. Particularly consequential because fusion permanently eliminates motion at the fused level, potentially destabilizing the actual diseased level.
• Pedicle screw placement at the wrong level. Even when the right levels are targeted, screws can be placed in the wrong level if counting fails.
• Wrong-side surgery. Right-side decompression when the pathology was left-sided — classified alongside wrong-level under the broader never-event category.

The published data on wrong-level spine surgery has a consistent pattern:

• Career incidence surveys. Studies asking spine surgeons whether they have ever performed a wrong-level procedure report high career-incidence rates across training programs and surveyed populations — often 10% or more.
• Sentinel event reports. The Joint Commission tracks wrong-site surgery through its sentinel event database. Spine procedures are consistently among the most-reported specific categories.
• Per-case incidence rates. The per-procedure rate is low (estimated at roughly 1 in 3,000 to 1 in 5,500), but applied across the hundreds of thousands of spine procedures performed annually in the U.S., the absolute number is meaningful.
• Likely underreporting. Internal data is often suppressed or normalized; published incidence likely understates the actual rate.

The spine-specific localization step has multiple components that must work together:

• Pre-operative imaging review. Before incision, the surgeon reviews the MRI or CT to confirm the level of pathology and the anatomic landmarks — transitional vertebrae, anatomic variants, fixed reference points like the sacrum or ribs.
• Intraoperative fluoroscopy or radiograph. After initial exposure, a localizing marker (typically a needle, clamp, or instrument) is placed at the suspected level and imaged. The image is correlated with pre-operative imaging.
• Counting from a fixed landmark. The surgeon counts vertebrae from a reliable reference — the sacrum, the first rib, the lumbosacral junction. Counting from unreliable landmarks (e.g., ribs that may have anatomic variants) contributes to errors.
• Team verification of the image. Surgeon, assistant, and imaging technologist should all agree on the level shown.
• Repeat imaging if uncertainty remains. When the initial image is unclear or the anatomy is ambiguous, additional imaging — different angle, CT-based navigation — may be required before proceeding.

When one or more of these steps is skipped or done perfunctorily, the wrong level becomes possible. The Joint Commission root-cause analyses of wrong-level events consistently identify localization failure as the proximate cause.

Recurring mechanisms of wrong-level surgery:

• Transitional vertebrae. Anatomic variants at the lumbosacral junction (lumbarization of S1 or sacralization of L5) produce counting confusion. Without pre-operative identification of the variant and careful counting, the surgeon can count one level off.
• Poor-quality intraoperative imaging. Overweight patients, poor fluoroscopy penetration, suboptimal beam angle — the localizing image may not clearly show the level.
• Image orientation errors. X-rays or fluoroscopy displayed rotated or inverted produce confusion about which level the marker is on.
• Counting from unreliable landmarks. Counting cervical levels from ribs or thoracic levels without a fixed reference produces errors.
• Schedule pressure. The time-out is abbreviated, the level verification feels perfunctory, the procedure proceeds.
• Hierarchy and team-culture failures. An assistant or technologist who suspects the wrong level is being operated on but feels unable to stop the procedure.
• Incomplete pre-operative planning. The plan did not note anatomic variants or fixed-landmark counting guidance.

The specific consequences that shape damages calculations:

• The wrong-level procedure cannot be reversed. Tissue altered is tissue altered. A fusion cannot be un-fused; a laminectomy cannot be un-done.
• The correct-level procedure is still required. The original pathology — the disc, the stenosis, the instability — remains and still needs treatment.
• Possible neurologic injury from the wrong-level procedure. Nerve root damage, chronic radicular pain, motor weakness — at the level that should not have been touched.
• Adjacent-segment disease. When a fusion is placed at the wrong level, adjacent levels take on abnormal stress and can develop accelerated degeneration.
• Psychological injury. Patients describe feelings of violation, loss of trust in medical care, and anxiety about further spine procedures. Significant and compensable.
• Prolonged recovery. Two spine procedures (wrong-level plus correct-level) mean two recoveries.

Non-wrong-level spine surgery claims also follow recognizable patterns:

• Pedicle screw malposition. Screws can breach the pedicle medially (into the spinal canal, with risk of nerve root or dural injury), laterally (with risk of neurovascular injury), inferiorly (into the disc or nerve root), or superiorly. Malpositioned screws can be asymptomatic or catastrophic; the breach analysis turns on technique and whether navigation or fluoroscopy was used appropriately.
• Inadequate decompression. When stenosis is not fully addressed, symptoms persist. If the technique fell short of the standard — incomplete foraminotomy, missed lateral recess decompression — revision is often required.
• Dural tear not recognized or repaired. Dural tears happen; unrepaired tears can cause persistent cerebrospinal fluid leak, headaches, and meningitis. Failure to recognize intraoperatively or address appropriately is the breach pattern.
• Missing neurologic deficit intraoperatively. When the standard of care called for neurophysiologic monitoring (e.g., during scoliosis correction, tumor resection) and monitoring was not used or was ignored.
• Anterior approach vascular injury. During anterior lumbar fusion, vascular structures at risk include the great vessels. Retraction injury, venous tear, arterial injury — catastrophic in worst cases.

Typical defendant mapping in a wrong-level spine surgery case:

• Operating surgeon. Primary defendant. Responsible for Universal Protocol adherence and, critically, for intraoperative level verification.
• Assistant surgeon or surgical resident. If involved in the time-out, the localization, or the decision to proceed.
• Radiology technologist. Who captured the localizing image and is responsible for image quality and orientation.
• Hospital. Vicariously liable for employed staff. Directly liable for institutional failures — inadequate localization protocols, insufficient fluoroscopy availability, culture of shortcuts.
• Neuromonitoring providers. In cases where intraoperative neurophysiologic monitoring was used or should have been used.

The damages arc in wrong-level spine surgery cases reflects the dual nature of the injury — the wrong procedure was performed and the correct procedure still must be:

• Past medical expenses. Wrong-level procedure, corrective procedure, additional hospitalization, rehabilitation, pain management.
• Future medical expenses. Ongoing care for any permanent neurologic consequence, adjacent-segment disease if fusion was performed at the wrong level, chronic pain management.
• Lost earnings. Measured in months rather than weeks for complex revision cases.
• Lost earning capacity. Where permanent neurologic impairment limits work options.
• Pain and suffering. Often substantial given the chronic nature of spinal injury and pain. Uncapped in Florida after Kalitan (2017).
• Disfigurement. Multiple surgical scars, potential neurologic appearance changes.
• Loss of consortium. When the injury has materially affected the marital or domestic relationship.

The documentary chain that wrong-level cases turn on:

• Pre-operative imaging. The MRI or CT that identified the pathology. Reviewed with the radiologist’s report describing the level.
• Pre-operative consent and plan. Documents the intended procedure and level.
• Operative report. The surgeon’s contemporaneous narrative, including any language about localization or verification.
• Intraoperative imaging. The localizing fluoroscopy or radiograph images — where available — show what the surgeon saw.
• Anesthesia and nursing OR records. Document the time-out and Universal Protocol compliance.
• Post-operative imaging. Shows the actual level operated on. Correlation with pre-operative imaging typically establishes the wrong-level error directly.
• Revision surgery records. When the correct level is subsequently addressed, the operative report may characterize the wrong-level error.

Florida Statute § 766.102 requires a corroborating expert affidavit before suit is filed. Spine surgery experts are typically board-certified orthopedic spine surgeons or neurosurgeons.
