We report a series of epidural hematomas which cause neurologic deterioration after spinal surgery, and have taken risk factors and prognostic factors into consideration. We retrospectively reviewed the database of 3720 cases of spine operation in a single institute over 7 years (1998 April- 2005 July). Nine patients who demonstrated neurologic deterioration after surgery and required surgical decompression were identified. Factors postulated to increase the postoperative epidural hematoma and t

Occurrence of HO is an inevitable postoperative complication after cervical ADR. The occurrence rate of HO was higher than our expectation. Moreover, definite differences in occurrence rate according to the prosthesis type were identified by this study.

OBJECTIVE: The goal of this study was to determine the relationship between cervical spine sagittal alignment and clinical outcomes after cervical laminoplasty in patients with ossification of the posterior longitudinal ligament (OPLL). METHODS: Fifty consecutive patients who underwent a cervical laminoplasty for OPLL between January 2012 and January 2013 and who were followed up for at least 1 year were analyzed in this study. Standing plain radiographs of the cervical spine, CT (midsagittal vi

STUDY DESIGN: Retrospective study. OBJECTIVES: To compare the efficacy of 2-level anterior cervical discectomy and fusion with cage alone (ACDF-CA) and with cage and plate construct (ACDF-CPC) with regard to clinical outcome and radiologic changes. SUMMARY OF BACKGROUND DATA: The use of stand-alone cervical interbody cages in ACDF has become popular, but high subsidence rates have been reported in the literature. METHODS: A total of 54 consecutive patients who underwent 2-level ACDF-CA or ACDF-C

Arthroplasty using the Bryan disc provided a favorable clinical and radiologic outcome thus far; however, we should not underestimate emergent adverse outcomes. To prevent postoperative sagittal imbalance after cervical arthroplasty, intentional modification in disc insertion angle and depth would be helpful. Unexpected compensatory biomechanical loads should be elucidated in future studies.

PCT may be useful in the diagnosing neurosurgical patients with postoperative fever of unknown origin.

PURPOSE: We have experienced 23 patients who had underwent cervical disc replacement with Mobi-C disc prosthesis and analyzed their radiological results to evaluate its efficacy. PATIENTS AND METHODS: This study was performed on 23 patients with degenerative cervical disc disease who underwent CDR with Mobi-C disc prosthesis from March 2006 to June 2006. RESULTS: The age of the study population ranged from 31 to 62 years with mean of 43 years, and 16 male and 7 female cases. Regarding axial pain

Although bony fusion had been completed, the effects of lumbar arthrodesis on adjacent segments could vary according to the surgical technique used for arthrodesis. Semirigid fixation combined with arthrodesis deserves careful consideration and further detailed study because it may cause less stress on adjacent segments than rigid fixation while maintaining the benefits of the latter procedure.

This study sought to determine the outcomes of posterior lumbar interbody fusion (PLIF), via a unilateral approach, in selected patients who presented with unilateral leg pain and segmental instability of the lumbar spine. Patients with a single level of a herniated disc disease in the lumbar spine, unilateral leg pain, chronic disabling lower back pain (LBP), and a failed conservative treatment, were considered for the procedure. A total of 41 patients underwent a single-level PLIF using two PE

HIRA's HUMS works well to monitor healthcare utilization of patients at the national level. The HUMS has a high-capacity hardware infrastructure and several operational programs that allows easy access to summaries as well as details to identify contributing factors for abnormality, but it has a limitation in that there is often a time lag between the provision of healthcare to patients and the filing of health claims.

BACKGROUND AND OBJECTIVES: Cervical laminoplasty is commonly used to treat cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL). Postoperative kyphotic changes can restrict spinal cord dorsal shift, leading to poor neurological outcomes. This study analyzes risk factors for loss of cervical lordosis (LCL) after laminoplasty in 3 groups: CSM, continuous OPLL, and other OPLL. It also evaluates postoperative changes in cervical spine parameters: C2-7
