Vertebroplasty and Kyphoplasty Complications: What Attorneys Need to Know About Cement Augmentation Litigation

Vertebroplasty and kyphoplasty are performed tens of thousands of times a year to stabilize painful vertebral compression fractures, most often in osteoporotic and cancer patients who have few other options for rapid pain relief. The procedures are minimally invasive and generally well tolerated, which is precisely why a bad outcome draws scrutiny: when bone cement escapes its intended space, migrates into the spinal canal, or embolizes to the lungs, the injury is frequently severe and the question of whether it reflects a recognized procedural risk or a technical departure becomes the center of the case. Attorneys evaluating these claims need an expert who performs vertebral augmentation routinely and can speak to what proper cement handling and imaging guidance actually require.

What Vertebroplasty and Kyphoplasty Involve

Both procedures inject acrylic bone cement (polymethylmethacrylate) into a fractured vertebral body under fluoroscopic or CT guidance to stabilize the fracture and relieve pain. Kyphoplasty adds a preliminary step — inflating a balloon within the vertebral body to create a cavity and partially restore height before the cement is injected at lower pressure. The central technical requirement across both procedures is continuous, high-quality fluoroscopic visualization of the cement as it is injected, because cement is radiopaque and its extravasation beyond the vertebral body is visible in real time if the physician is watching closely enough and stops the moment leakage begins. A case built on a poor outcome without evidence that the physician was monitoring cement flow throughout the injection, not just before and after, is a case built on a real gap in the standard of care.

Cement Leakage Into the Spinal Canal

The most serious complication is posterior cement leakage into the epidural space or spinal canal, which can cause acute cord or nerve root compression requiring emergent decompressive surgery. Leakage of some degree occurs in a meaningful minority of cases and is not, by itself, evidence of malpractice — the relevant question is whether the physician recognized the leak as it began and stopped injecting, and whether the needle trajectory and cement viscosity were appropriate for a vertebral level where the posterior wall was already compromised by the fracture. A pre-procedure CT or MRI showing posterior vertebral body wall disruption is a recognized risk factor that should prompt a lower-pressure, smaller-volume technique or, in some cases, a decision to forgo the procedure — proceeding with a standard high-volume injection into a vertebra with a known posterior wall breach, without adjusting technique, is a pattern worth close review.

Cement Pulmonary Embolism

Cement can also enter the vertebral venous plexus and travel through the venous system to the lungs, producing a pulmonary cement embolism that ranges from asymptomatic and incidental to acutely fatal. Venography before cement injection — confirming venous drainage patterns and avoiding injection when a large venous channel is filling readily — is a technique some practitioners use specifically to reduce this risk, and its use or omission, along with the injected cement's viscosity at the time of administration, is relevant to whether the physician took reasonable precautions. Post-procedure imaging that identifies a pulmonary cement embolus should prompt immediate clinical evaluation regardless of whether the patient is symptomatic, and a delayed recognition of respiratory symptoms following a same-day vertebral augmentation procedure warrants scrutiny of the discharge and monitoring process.

Adjacent-Level Vertebral Fracture

A well-documented complication of vertebral augmentation is fracture of an adjacent vertebral body in the weeks to months following the procedure, thought to result at least in part from the altered biomechanical stiffness the cemented vertebra introduces to the surrounding spine. This is a recognized risk of the procedure itself in an osteoporotic spine and is rarely, standing alone, evidence of a standard-of-care departure — but cases can turn on whether the patient was appropriately counseled about this risk during informed consent, and whether ongoing osteoporosis management was addressed as part of the treatment plan rather than treating the augmentation as a standalone fix disconnected from the patient's underlying bone disease.

Patient Selection and the Threshold Question

Before any technical analysis, the expert must evaluate whether the patient was an appropriate candidate in the first place. Vertebral augmentation is indicated for painful compression fractures that have failed or are unlikely to respond to conservative management, confirmed by correlating the fracture level on imaging with the patient's reported pain location and, where the diagnosis is ambiguous, MRI evidence of bone marrow edema indicating an acute or subacute fracture. A procedure performed on a chronic, non-painful, or radiographically healed fracture — or at a level that does not correlate with the patient's actual pain — raises a threshold question about the indication for the procedure independent of how technically well it was performed.

Building the Causation Case

Causation analysis in vertebral augmentation litigation requires the expert to connect the specific complication to a specific point in the procedure and rule out the recognized baseline risk that exists even with proper technique. In a cement leakage case, that means correlating the location and volume of the leak visible on post-procedure imaging with the fluoroscopic images taken during injection, and assessing whether a competent physician monitoring the injection in real time would have stopped sooner. In an adjacent-level fracture case, the timeline and the patient's documented bone density and osteoporosis treatment status matter more than the technical conduct of the index procedure itself.

Critical Documentation for Case Evaluation

Attorneys evaluating a potential vertebral augmentation case should obtain the pre-procedure imaging used to select the treatment level and assess posterior wall integrity, the informed consent document and its discussion of cement leakage, embolism, and adjacent-level fracture risk, all intraprocedural fluoroscopic images (not just still captures before and after cement injection), any venography images if performed, the anesthesia and recovery record documenting immediate post-procedure monitoring, and post-procedure imaging obtained in response to any new symptoms.

How ApexMedLaw Supports Vertebral Augmentation Litigation

Vertebroplasty and kyphoplasty litigation requires an expert who performs these procedures as part of an active interventional pain or spine practice and can speak credibly to fluoroscopic cement monitoring, patient selection criteria, and the line between a recognized procedural risk and a technical departure. Our pain medicine experts bring that procedural experience to case review.

We provide detailed review of intraprocedural fluoroscopic imaging against the documented outcome, assessment of patient selection and pre-procedure imaging workup, evaluation of informed consent documentation against the complications at issue, and causation opinions connecting specific technical findings to the patient's clinical injury.
