[Repeated cervical laminoplasty for progressive ossification of posterior longitudinal ligament: a case report]. / Povtornaya lyaminoplastika sheinogo otdela pozvonochnika pri progressiruyushchei ossifikatsii zadnei prodol'noi svyazki: klinicheskii sluchai.

Posterior longitudinal ligament ossification is a progressive disease resulting in severe multilevel spinal stenosis with myelopathy. Decompression via anterior or posterior approach is the main treatment option. Decompressive laminoplasty is currently considered the most effective and safest method. This procedure provides favorable outcomes with low trauma and short surgery time. Redo surgeries are rare and most often performed within 2 years after primary laminoplasty. The most common causes are progressive spinal stenosis following posterior longitudinal ligament ossification, insufficient primary decompression and progressive cervical spine kyphosis. Considering few data on redo laminoplasty, we present a patient with progressive ossification of posterior longitudinal ligament who underwent redo surgery at the same level in 10 years after primary laminoplasty.

[The effect of spinal cord stretching on development of spondylogenic cervical myelopathy associated with kyphotic spinal deformity]. / Znachenie rastiazheniia spinnogo mozga v formirovanii spondilogennoi tservikal'noi mielopatii na fone kifoticheskoi deformatsii pozvonochnika.

OBJECTIVE: The study objective was to specify the role of spinal cord stretching in the pathogenesis of spondylogenic cervical myelopathy associated with kyphotic spinal deformity. MATERIAL AND METHODS: We analyzed long-term outcomes of surgical treatment for spondylogenic cervical myelopathy accompanied by kyphotic spinal deformity. RESULTS: The surgical treatment outcomes were significantly better (p<0.000001) in the case of simultaneous decompression/correction of kyphotic deformity and spine stabilization. CONCLUSION: Spinal cord stretching associated with kyphotic spinal deformity significantly contributes to the pathogenesis of clinical manifestations of spondylogenic cervical myelopathy.
