Posterior Short Segment Fixation and Fusion and in a Displaced Hangman's Fracture
홍재택,이상원,손병철,김문찬 대한신경외과학회 2004 Journal of Korean neurosurgical society Vol.35 No.6
Although most cases of C2 traumatic spondylolisthesis, a so called Hangman's fracture, can be managed by a closed reduction and immobilization, surgery should be considered in the cases of non-reducible fractures or a recurrent subluxation. This report details our recent experience with the surgical treatment of a Type II Hangman’s fracture after an unsuccessful closed reduction. Advantage and the technique of the posterior short segment fixation are discussed.
A Case of Intramedullary Spinal Cord Astrocytoma Associated with Neurofibromatosis Type 1
홍재택,이상원,손병철,김문찬 대한신경외과학회 2004 Journal of Korean neurosurgical society Vol.36 No.1
The authors report a symptomatic intramedullary spinal cord astrocytoma in the thoracolumbar area associated with neurofibromatosis type 1 (NF-1). A 38-year-old woman presented with paraparesis. Magnetic resonance imaging revealed an intramedullary lesion within the lower thoracic spinal cord and conus medullaris, which was removed surgically. Pathological investigation showed anaplastic astrocytoma. This case confirms that the diagnosis criteria set by the National Institute of Health Consensus Development Conference can be useful to differentiate ependymoma from astrocytoma when making a preoperative diagnosis of intramedullary spinal cord tumor in patients of NF-1.
Surgical Experiences of the Tarsal Tunnel Syndrome
홍재택,이상원,손병철,성재훈,김인수,김문찬 대한신경외과학회 2004 Journal of Korean neurosurgical society Vol.36 No.6
Objective : Tarsal tunnel syndrome is a rare compressive neuropathy. In Korea, the reported cases of the tarsal tunnel syndrome are mainly related to diagnosis, so there are only a few reports about the surgical result. We report the significance of the decompressive surgery for the tarsal tunnel syndrome. Methods : Seven patients with tarsal tunnel syndrome were treated surgically. The patients were aged 31-70 years (mean 53.1 years), and all of them complained of pain or dysesthesia of the sole of the foot. The posterior tibial nerve and its branches were decompressed through the flexor retinaculum and under the abductor hallucis muscle fascia. Results : Surgical decompression was beneficial in most patients with tarsal tunnel syndrome in their feet. Neither wound infection nor recurrence of symptoms was found during the follow up period (mean 12.9 months). Conclusion : Surgical decompression is the good option for the treatment of the tarsal tunnel syndrome, especially in the cases of short symptom duration or mass lesion.

Although cervical spinal deformity (CSD) can have a profoundly negative impact on an individual’s quality of life and there have been many advances in surgical treatment of CSD in recent years, there exists no comprehensive classification system of surgical treatment that categorizes anterior and posterior surgery separately according to the grade of surgery. The objective of this study is to introduce the new classification system of various surgical treatments for CSD. We developed a new classification system (SOF system) for CSD surgery that describes the sequence of surgical approach (S), the grade of osteotomy (O), and the information of fixation (F) using alphanumeric codes. This new classification system can provide a consistent description of the various osteotomies performed in CSD surgery. Especially, regarding research, there has been a clear benefit to this classification. Having a standardized classification that allows for common frame for cervical deformity correction surgery, communication between surgeons and the evaluation of the CSD surgeries make it possible to conduct global comparative research about surgical outcome.
Evaluation and Surgical Planning for Craniovertebral Junction Deformity
홍재택,김일섭,이호진,박종혁,허정우,이종범,이정재,이상효 대한척추신경외과학회 2020 Neurospine Vol.17 No.3
Craniovertebral junction (CVJ) deformity is a challenging pathology that can result in progressive deformity, myelopathy, severe neck pain, and functional disability, such as difficulty swallowing. Surgical management of CVJ deformity is complex for anatomical reasons; given the discreet relationships involved in the surrounding neurovascular structures and intricate biochemical issues, access to this region is relatively difficult. Evaluation of the reducibility, CVJ alignment, and direction of the mechanical compression may determine surgical strategy. If CVJ deformity is reducible, posterior in situ fixation may be a viable solution. If the deformity is rigid and the C1–2 facet is fixed, osteotomy may be necessary to make the C1–2 facet joint reducible. C1–2 facet release with vertical reduction technique could be useful, especially when the C1–2 facet joint is the primary pathology of CVJ kyphotic deformity or basilar invagination. The indications for transoral surgery are becoming as narrow as a treatment for CVJ deformity. In this article, we will discuss CVJ alignment and various strategies for the management of CVJ deformity and possible ways to prevent complications and improve surgical outcomes.
