On the 16th, Barunsegae Hospital (Director Seo Dong-won) published a thesis titled “Radiological Risk Factors of Proximal Adjacent Segment Failure According to Age in Adult Spinal Deformity” by Geun-ho Lee (Orthopedic Surgeon, Director of Spine Center) in an international journal called Clinics in Orthopedic Surgery. ) was listed.”
Proximal adjacent segment failure, one of the serious complications that may require reoperation in adult spinal deformity, is related to the age of the patient, and it is known that older patients tend to have more proximal adjacent segment failure. Proximal adjacent segment failure refers to the loss of movement when vertebrae and bones are attached through fusion, so the movement of the upper and lower nodes and discs adjacent to the surgical site increases, and the shock and stress of the fused nodes are added, resulting in unstable adjacent segments following surgery and nerves. This means that it causes rapid degeneration, such as pain caused by being pressed.
In this study, a total of 186 patients who underwent thoracolumbar or lumbar fusion to prevent possible complications following lumbar fusion (long segment deformity fusion) were divided into two groups: a group under 70 years of age and a group over 70 years of age. The study was conducted under the assumption that radiological risk factors would be different. A total of 186 patients (90.3% female) were followed up and analyzed the time and age at which proximal adjacent segmental failure appeared following surgery. . In particular, in the case of patients under 70 years of age, multifactor statistical analysis showed that the change in lumbar lordosis before and following surgery was a risk factor for proximal adjacent segment failure, and overcorrection was a risk factor for proximal adjacent segment failure in the case of patients aged 70 years or older.
The results of this study demonstrated that different approaches are needed according to age to prevent postoperative complications during lumbar fusion (long segment deformity fusion). Corresponding author, Dr. Lee Geun-ho (orthopedic surgeon), said, “Spine fusion is a surgical procedure performed on severe spinal stenosis, spondylolisthesis, spondylolisthesis, and herniated discs. It is a treatment that relieves pain by restoring stability to an unstable spine.” “However, there have been many people who have endured the pain while postponing or putting off surgery due to anxiety regarding the possibility of reoperation due to adjacent segmental disease,” he explained. Director Lee said, “Through the results of this study, we expect to prevent complications following lumbar fusion by identifying and preparing for the risk factors of adjacent segment failure according to age, and to reduce concerns regarding reoperation, thereby increasing the satisfaction of surgery.”
