Recurrent ossification of the posterior longitudinal ligament in the upper thoracic region 10 years after initial decompression.

Background: Posterior decompression surgery consisting of laminoplasty is generally considered be the treatment of choice for upper thoracic OPLL. Here, we describe a patient who, 10 years following a C3-T4 level laminectomy, developed recurrent OPLL at the T2-3 level with kyphosis requiring a posterior fusion. Case Description: A 64-year-old male with CT documented OPLL at the C3-4, C6-7, and T1-4 levels, originally underwent a cervicothoracic laminectomy with good results. However, 10 years later, when T2-3 OPLL recurred along with kyphosis, he warranted an additional posterior fusion. Conclusion: Due to the long-term risks of developing kyphotic deformity/instability, more patients undergoing initial decompressive surgery alone for upper thoracic OPLL should be considered for primary fusions.
