Biomechanical assessment of proximal junctional semi-rigid fixation in long-segment thoracolumbar constructs.

Authors:

J Neurosurg Spine 2018 Oct 1:1-9. Epub 2018 Oct 1.

OBJECTIVEProximal junctional kyphosis (PJK) and failure (PJF) are potentially catastrophic complications that result from abrupt changes in stress across rigid instrumented and mobile non-fused segments of the spine (transition zone) after adult spinal deformity surgery. Recently, data have indicated that extension (widening) of the transitional zone via use of proximal junctional (PJ) semi-rigid fixation can mitigate this complication. To assess the biomechanical effectiveness of 3 semi-rigid fixation constructs (compared to pedicle screw fixation alone), the authors performed cadaveric studies that measured the extent of PJ motion and intradiscal pressure changes (ΔIDP).

Postoperative Cervical Sagittal Realignment Improves Patient-Reported Outcomes in Chronic Atlantoaxial Anterior Dislocation.

Oper Neurosurg (Hagerstown) 2018 Dec;15(6):643-650

Spine Surgery, Department of Ortho-paedics, The First Affiliated Hospital of Nanchang University, Nanchang, China.

Background: Chronic atlantoaxial anterior dislocation (AAD) not only results in myelopathy, but dislocation-related kyphosis also results in cervical malalignment, which permanently affects neck function and patient-reported outcomes (PROs).

Objective: To investigate the effect of kyphotic correction on realigning cervical spine and independent cervical alignment parameters, which may be correlated with an improvement of PROs.

Methods: The study included 21 patients with chronic AAD-related kyphosis who underwent C1-2 reduction and correction surgery. Read More
