A retrospective study.The purpose of this study was to determine, using survivorship analysis, the rate adjacent segment pathology (ASP) development and identify risk factors for reoperation.The Hilibrand defined "adjacent disease" as symptomatic radiculopathy or myelopathy due an documented on 2 consecutive office visits. In addition being somewhat subjective, their criterion is not practical identifying by need reoperation.This a analysis 1038 patients who underwent primary anterior...

In Brief Study Design. Prospective study. Objective. To identify the impact of laminoplasty on range motion (ROM) and sagittal alignment cervical spine. Summary Background Data. Cervical is an effective procedure decompressing multilevel spinal cord compression. Preoperative lordosis spine a prerequisite for laminoplasty, maintaining postoperative also important decompression cord. Materials Methods. Eighty-five patients who planned open door from C3–C7 were studied. diagnosis included...

In Brief Study Design. A prospective, randomized study. Objective. To analyze the effect of local retropharyngeal steroid to reduce prevertebral soft tissue swelling (PSTS) after anterior cervical discectomy and fusion (ACDF). Summary Background Data. There have been several reports on intravenous corticosteroid prevent airway complication without a consensus; however, there no date that discussed use steroids PSTS. Methods. Fifty cases underwent ACDF involving 1 or 2 segments were enrolled....

Background: Adjacent-segment pathology is an important issue involving the cervical spine, but there have been few comprehensive studies of this problem. The purpose current study was to determine risk factors for adjacent-segment and compare survivorship adjacent segments in patients who underwent spine operations including arthrodesis motion-sparing procedures. Methods: This a retrospective analysis consecutive series 1358 with radiculopathy, myelopathy, or myeloradiculopathy surgery...

A retrospective study.To analyze incidence of asymptomatic cervical cord compression and related factors in lumbar stenosis patients.Neural resulted from degenerative disc is not unusual the spine. However, its clinically patients have been studied.We analyzed index (LSI), (CCI), Torg-Pavlov ratio whole spine magnetic resonance images 93 patients. We compared involving a single segment versus multiple segments cases with LSI double-level or more, 60s 70s, male female for above variables.Of...

Ovarian microcystic stromal tumor (MCST ) is a very rare neoplasm; hence, its nomenclature was recently designated as “Distinctive morphologic and immunohistochemical features” in 2009. Its exact origin, etiological genetic alterations, background are not yet clearly known. Familial adenomatous polyposis (FAP) an autosomal dominant disease that leads to development of colorectal polyps via germ‐line mutations the APC gene on chromosome 5q21∼22. In this study, we report 40‐year‐old female...

This study was designed to reevaluate the effectiveness of Pavlov ratio in patients with cervical myelopathy.We studied 107 who underwent open door laminoplasty for treatment myelopathy between C3 C7 levels. We determined on preoperative and postoperative spine lateral radiographs, vertebral body-to-canal sagittal reconstruction CT scans, body-to-cerebrospinal fluid (CSF) column T2-weighted MR images from C6. The severity using JOA score both images. recovery rate also calculated. plain...

A retrospective study.To present the accuracy and safety of a novel "key slot (KS)" technique for cervical pedicle screw (CPS) placement with learning curve.Safety curve are issues preventing wide acceptance CPS. On basis local anatomy pedicle, authors modified conventional to increase comfortableness CPS minimal bone loss.A total 277 subaxial in 50 patients had been inserted using author's were reviewed. The KS-shaped entry was created on medial half lateral mass 3 mm cutting burr. shape...

In Brief Study Design. A case report. Objective. To report the successful consecutive spinal osteotomies of multiple segments performed on a patient with extremely severe kyphotic deformity. Summary Background Data. There have been no reports experience and surgical strategy osteotomy for global spine Methods. 48-year-old man, ankylosing spondylitis "chin-on-pubis" deformity, underwent to correct severe, fixed kyphosis. The axial skeletons from skull, all vertebrae, both sacroiliac joints...

Ankylosing spondylitis is a chronic inflammation that results in progressive ossification of the ligaments and joints spine.Pain stiffness are hallmarks this disease especially axial skeleton these symptoms progress upwards.Eventually, spine becomes stiff global kyphosis fixed due to loss lumbar lordosis increased thoracic kyphosis.Back pain occurs positive balance horizontal gaze difficult as progresses.Because combined reasons, normal social activities affected.The major concerns (90%),...

A retrospective studyTo classify the types and identify related factors on sagittal decompensation after corrective osteotomy for lumbar degenerative kyphosis (LDK).There has been a skeptical view of surgical treatment LDK owing to loss balance even correction kyphosis. However, there had no report classification risk decompensation.A total 23 patients who undergone were enrolled. The mean follow-up period was 45.7 months. Radiographic parameters including balance, cross-sectional area...

This study aimed to determine the feasibility and safety of adenomyomectomy with transient occlusion uterine arteries (TOUA) in patients symptomatic diffuse adenomyosis.Twenty-six adenomyosis underwent TOUA by a single surgeon at Ulsan University Hospital between May 2011 September 2012. Surgical outcomes included operative time, intraoperative injury blood vessels, nerves, pelvic organs loss. We assessed degree improvement dysmenorrhea menorrhagia 4-month follow-up after completion adjuvant...

To determine the accuracy of frozen section diagnosis and factors associated with final pathological upgrade in patients mucinous ovarian tumors.This study included 1,032 tumors who underwent during surgery. Sensitivity, specificity, diagnostic was calculated. Univariate multivariate regression analyses were performed to pathology report.The sensitivity specificity 99.1% (95% confidence interval [CI]=98%-99.6%) 82.2% CI=77.9%-85.7%), respectively, for benign tumors; 74.6% CI=69.1%-79.4%)...
