Recurrence of Local Kyphosis After Percutaneous Kyphoplasty: The Neglected Injury of the Disc-Endplate Complex.

Background: Recurrent of local kyphosis after percutaneous kyphoplasty (PKP) is rarely reported and discussed. Literatures reported that re-kyphosis is usually a consequence of refractures of augmented or adjacent vertebra. However, whether re-kyphosis should be considered as a complication of refractures and has an impact on clinical efficacy of PKP during follow-up time is unknown.
