Article Synopsis
- * An analysis of 110 patients showed that 14.5% experienced rod fractures, with notable risk factors including larger changes in lumbar lordosis, pre-existing vertebral fractures, and smaller rod diameters (6 mm or less).
- * The research concludes that pre-existing vertebral fractures and the degree of lumbar lordosis change are key independent risk factors for rod fractures, suggesting surgeons should incorporate these considerations in preoperative planning.
Objective: This study aimed to identify risk factors for postoperative proximal junctional kyphosis (PJK) with vertebral fracture in adult spinal deformity (ASD) patients. We performed a survival analysis considering various factors, including osteoporosis.
Methods: This single-center retrospective study included 101 ASD patients (mean age: 67.
Purpose: To identify risk factors, including FRAX (a tool for assessing osteoporosis) scores, for development of proximal junctional kyphosis (PJK), defined as Type 2 in the Yagi-Boachie classification (bone failure), with vertebral fracture (VF) after surgery for symptomatic adult spinal deformity.
Methods: This was a retrospective, single institution study of 127 adults who had undergone corrective long spinal fusion of six or more spinal segments for spinal deformity and been followed up for at least 2 years. The main outcome was postoperative development of PJK with VF.
Background: Corrective surgery for adult spinal deformity has recently been increasingly performed because of aging populations and advances in minimally invasive surgery. Low bone mineral density is a major contributor to proximal junctional kyphosis after spinal long fusion. Assessment for low bone mineral density ideally involves both dual energy X-ray absorptiometry and identification of pre-existing vertebral fractures, the latter, requiring only standard equipment, being performed more frequently.
