Busan Bumin Hospital's Chief Seok Sangyun Identifies Prognostic Factors in Degenerative Spinal Deformity Surgery

Analysis of Causes of Lordosis Loss After Deformity Correction for Degenerative Kyphosis... Published in Neurosurgery

Busan Bumin Hospital announced on the 5th that Seok Sangyun, Chief of the Spine Center and neurosurgeon (corresponding author), had published research findings on prognostic factors for surgery in patients with degenerative spinal deformity in Neurosurgery (SCIE), a leading international journal in the field of neurosurgery.

Neurosurgery is the official journal of the Congress of Neurological Surgeons (CNS) in the United States and has been regarded as a top-tier journal representing the global field of neurosurgery since its launch in 1977. Its 5-year impact factor is approximately 4.3.

This study was conducted as a joint research project with Professor Hwang Changjoo of Asan Medical Center in Seoul, under the title "Fusion Construct Settling Down After Deformity Correction for Degenerative Sagittal Imbalance." The researchers analyzed the phenomenon of fusion construct settling that occurs after deformity correction surgery in patients with degenerative sagittal imbalance. In particular, they focused on patients with degenerative kyphosis, a condition commonly seen in older adults, and closely examined the prevalence and causes of decreased lumbar lordosis after deformity correction using combined anterior and posterior approaches.

The study found that the decrease in lumbar lordosis, which frequently occurs after combined anterior and posterior surgery, is not caused solely by vertebral endplate injury or cage subsidence as previously known. Rather, it showed a tendency for a more frequent decrease in lordosis within approximately three months after surgery in cases where procedures including posterior column osteotomy were performed, suggesting that this factor needs to be thoroughly considered when planning lordosis correction before surgery.

Seok Sangyun said, "In the field of spinal deformity, not only adolescent idiopathic scoliosis but also so-called 'bent-back disease,' or degenerative kyphosis in the elderly, has recently emerged as an important issue. If surgeons sufficiently take prognostic factors into account when planning surgery, it can provide substantial help to those performing deformity correction procedures." He added, "We will continue to study ways to improve postoperative outcomes in patients with spinal deformity."
