A 16-year-old male patient with severe kyphoscoliosis, paraplegia, and neurogenic bowel/bladder caused by a juvenile pilocytic astrocytoma was treated surgically using a hybrid fusion construct with polyethylene bands after neoplasm resection. Owing to the necessity of serial postoperative magnetic resonance imaging studies to evaluate the recurrence of pathology and known effect of metal artifact from spinal instrumentation, preservation of radiographic resolution was critical.
We describe the novel utility of polyethylene bands placed around the ribs as a safe and effective form of hybrid construct for reducing radiographic metal artifact in spinal deformity cases requiring serial imaging.
一名 16 岁男性患者，因幼年毛细胞星形细胞瘤导致严重的脊柱后凸侧凸、截瘫和神经性肠/膀胱，在肿瘤切除后采用聚乙烯带杂交融合结构进行手术治疗。由于需要进行连续的术后磁共振成像研究来评估病理复发和已知的脊柱器械金属伪影的影响，因此保持影像学分辨率至关重要。
我们描述了一种新的方法，即在肋骨周围放置聚乙烯带作为一种安全有效的杂交结构，用于减少需要连续成像的脊柱畸形病例中的放射金属伪影。
