Implication

Observational study demonstrates a 5.6% rate of acute proximal junctional failure after adult spinal deformity surgery, indicating failure modes vary by upper instrumented vertebra location.

Key Points

Determine the incidence, anatomical distribution, and failure mechanisms of acute proximal junctional failure following surgical correction of adult spinal deformity.
Evaluated patients undergoing surgical correction for adult spinal deformity to monitor for acute proximal junctional failure (APJF).
Analyzed failure mechanisms (fracture versus soft-tissue failure) relative to the level of the upper instrumented vertebra (UIV).
Acute proximal junctional failures occurred in 5.6% of patients following spinal deformity surgery.
Failures manifested predominantly in the thoracolumbar region of the spine.
Failure mode differed by upper instrumented vertebra level, with thoracolumbar junctions failing primarily via fracture and upper thoracic junctions failing predominantly through soft-tissue disruption.
