Abstract BACKGROUND: The failure modes, time to development, and clinical relevance are known differ between proximal junctional kyphosis (PJK) (PJF). However, there no reports that study the risk factors of PJK PJF separately. OBJECTIVE: aim this was investigate for METHODS: A retrospective 160 consecutive patients who underwent a long instrumented fusion sacrum adult spinal deformity with minimum follow-up 2 years conducted. separate survivorship analysis performed using Cox proportional...
Abstract Background Comparatively little is known about the relation between sagittal vertical axis and clinical outcome in cases of degenerative lumbar spondylolisthesis. The objective this study was to determine whether balance affects outcomes after posterior interbody fusion. This series suggests that consideration during fusion for spondylolisthesis can yield high levels patient satisfaction restore spinal Methods A retrospective a radiological review performed on 18 patients with one...

In present study, clinical features and prognostic factors OLF were examined large number Korean patients.Data 51 consecutive patients who underwent decompressive laminectomy with or without fusion for between 1998 2008 retrospectively analyzed. Patients evaluated pre- postoperatively using...
In accordance with extending survival periods of cancer patients, number consecutively developing metastatic spinal tumor is also increasing. There have been improvements in the treatment results spine by virtue developments diagnostic radiology, chemotherapy, adjuvant treatment, operative device and technique, discrete preoperative plan, standardized operation. Accordingly, surgical indication has increased. Clinically, case tumor, itself should be focused on pain relief, preservation...
Retrospective study.To validate the age-adjusted ideal sagittal alignment in terms of proximal junctional failure (PJF) and clinical outcomes.It is reported that optimal correction with regard to reduces risk PJF development. However, few studies have validated this concept. The age-considered likely be undercorrection conventional surgical target, such as pelvic incidence (PI)-lumbar lordosis (LL) within ±9°. Therefore, impact should evaluated along radiographic effect.Adult spinal...
Four guidelines have been suggested for optimal correction in adult spinal deformity surgery: Scoliosis Research Society (SRS)-Schwab classification, age-adjusted sagittal alignment goals, Global Alignment and Proportion (GAP) score, the Roussouly algorithm. Whether these goals provide benefit both proximal junctional kyphosis (PJK) reduction clinical outcome improvement remains unclear.To validate 4 preoperative surgical planning tools PJK development outcomes.We retrospectively reviewed...
Study Design. Retrospective study. Objective. The aim of this study was to investigate the risk factors for proximal junctional failure (PJF) following long instrumented fusion stopping at thoracolumbar junction (TLJ) in adult spinal deformity (ASD) and determine which cases are suitable TLJ stop without increasing PJF. Summary Background Data. PJF ASD is a well-recognized complication that negatively affects clinical outcomes. Generally, uppermost vertebra (UIV) associated with Little known...
A single case history is worthy of report if it presents a previously unrecognized condition or sheds further light on unproven concepts pathogenesis treatment. The present seems to fulfill both criteria. Congenital cutaneous defects the scalp are quite rare. When they occur appear as variously discolored areas completely devoid hair, usually over vertex head. They range in size from circular lesions 1-2 cm. diameter large embracing anterior and posterior fontanelles narrower area between....
A retrospective study.To determine the critical length of fusion that warrants additional stronger fixation in lumbosacral (L-S) fusion, and to analyze risk factors nonunion at L-S junction.Long lever arm down S1 requires than short fusion. However, no published criteria are available about requiring ilium or S2 obtain adequate stability for union junction.A total 327 adult patients with degenerative lumbar disease, who were treated instrumented including junction, included this study. Mean...
Study Design. A retrospective analysis. Objective. To evaluate the long-term clinical and radiographic outcomes to investigate who achieved successful after lumbar total disc replacement (TDR) using ProDisc II. Summary of Background Data. There are few evidences regarding efficacy safety TDR. Furthermore, it has not been addressed which patients good in follow-up. Methods. Data at 1-, 2-, 5-, 7-year, last follow-up were used for According presence combined pathologies, categorized as groups...
A case is presented in which multiple well differentiated sebaceous glands are demonstrated within the parenchyma of parotid gland. The possible relationship such structures to origin so-called “mixed tumors” suggested.
Study Design Retrospective study. Objective This study aimed to identify the key determinants of long-term patient satisfaction after adult spinal deformity (ASD) surgery. Methods Data 393 patients who underwent long-segment fusion for ASD were retrospectively analyzed. Patients classified into highly satisfied (HS) and less (LS) groups based on mean scores Scoliosis Research Society-22 (SRS-22) questionnaire at final follow-up. Demographic data, surgical variables, radiographic parameters,...
Study Design A multinational, multiethnic, cross-sectional image-based study was performed in 33 institutions, representing 10 countries, which were part of the AOSpine Asia Pacific Research Collaboration Consortium. Objective Lumbar facet joint orientation has been reported to be associated with development degenerative spondylolisthesis (DS). The role ethnicity regarding remains uncertain. As such, following across a wide-ranging population base assess patients DS region. Methods Lateral...
OBJECTIVE Short-segment fusion (SSF) is an effective surgical option for appropriately selected patients with de novo degenerative lumbar scoliosis (DNDLS). Considering that DNDLS frequently accompanied by multisegment degeneration and potential instability across the entire segments, it inevitable unhealthy segments remain after SSF, thereby increasing risk of adjacent-segment disease (ASD) occurrence. Therefore, authors aimed to identify factors ASD in who underwent SSF. METHODS This...
OBJECTIVE Conventional decompression surgery for beak-type ossification of the posterior longitudinal ligament (OPLL) thoracic spine, whether approached anteriorly or posteriorly, poses several challenges, including technical complexity, cerebrospinal fluid leakage, incomplete decompression, and potential neurological deterioration. Therefore, authors introduce a novel technique, anterior sliding osteotomy (ASDO), myelopathy caused by OPLL evaluate efficacy safety this technique. METHODS Six...
