Neurogenic heterotopic ossification (NHO) is a common complication in patients with spinal cord injury (SCI) and traumatic brain injury (TBI). Although there are many reports regarding the etiology, pathophysiology, and medical management, few studies elaborate the anatomical details of NHO, which leads to ankylosis of the hip joint. A prospective study on surgical resection of NHO in patients with hip ankylosis was conducted. Radiography and magnetic resonance imaging (MRI) were used to assess the relationship of the NHO block with the blood vessels, peripheral nerve, and surrounding muscles and bones. The anatomical relationships were also assessed and documented during the surgical procedures. NHO, which is anterior to the hip and causes hip ankylosis, settles into tissue planes without involving the tissue itself and does not disrupt the femoral neurovascular structures. The NHO bone block can then fuse to the cortex of adjacent bone. During resection, the normal bony contour should be exposed as a marker to guide the resection in order to avoid iatrogenic fracture.
神经源性异位骨化（NHO）是脊髓损伤（SCI）和创伤性脑损伤（TBI）患者常见的并发症。尽管有许多关于病因、病理生理学和药物治疗的报道，但很少有研究详细阐述导致髋关节强直的NHO的解剖细节。对髋关节强直患者的NHO手术切除进行了一项前瞻性研究。使用X线摄影和磁共振成像（MRI）评估NHO块与血管、周围神经以及周围肌肉和骨骼的关系。在手术过程中也对解剖关系进行了评估和记录。位于髋关节前方并导致髋关节强直的NHO，位于组织平面内，不涉及组织本身，也不破坏股神经血管结构。然后，NHO骨块可与相邻骨的皮质融合。在切除过程中，应暴露正常的骨轮廓作为标记以指导切除，以避免医源性骨折。
