Proximal junctional kyphosis and proximal junctional failure

Neurosurg Clin N Am. 2013 Apr;24(2):213-8. doi: 10.1016/ Epub 2013 Feb 21.


Proximal junctional failure (PJF) should be distinguished from proximal junctional kyphosis, which is a recurrent deformity with limited clinical impact. PJF includes mechanical failure, and is a significant complication following adult spinal deformity surgery with potential for neurologic injury and increased need for surgical revision. Risk factors for PJF include age, severity of sagittal plane deformity, and extent of operative sagittal plane realignment. Techniques for avoiding PJF will likely require refinements in both perioperative and surgical strategies.
