Understanding the natural history of the spinopelvic alignment in adolescent idiopathic scoliosis (AIS) is important in developing surgical strategies for patients with adult idiopathic lumbar scoliosis (AdLS). Because it is challenging to follow individuals without any treatments, we sought to estimate its natural history by comparing radiographic characteristics of patients with AIS and AdLS.
We included patients with Lenke 5 AIS and patients with AdLS who were diagnosed with Lenke 5 AIS in adolescence. The Cobb angle of the curve and spinopelvic parameters were measured by whole spine radiographs. The AdLS patients were divided into 2 groups according to age <50 years (AdLS<50) or ≥50 years (AdLS≥50). Radiographic parameters were compared among the AIS, AdLS<50, and AdLS≥50 groups. The relationship between age and each parameter was analyzed using nonlinear regression analysis.
We analyzed 40 patients with AIS (all female, mean age 16.8 ± 3.2 years) and 35 patients with AdLS (34 female and 1 male, mean age 55.4 ± 12.1 years). Thoracolumbar/lumbar curve and thoracolumbar kyphosis was significantly greater in the AdLS<50 group compared with the AIS group, without progression after age 50 years. Lumbar lordosis and pelvic tilt deteriorated linearly with age. AIS and AdLS<50 patients maintained sagittal balance, which deteriorated in AdLS≥50 patients.
Our results may predict the following natural course of Lenke 5 AIS (1) progression of scoliotic deformity of thoracolumbar/lumbar curve with increased thoracolumbar kyphosis; (2) subsequent lumbar hypolordosis followed by pelvic retroversion; and (3) sagittal imbalance after failure of compensation.

Postoperative spinal epidural hematoma is a rare complication of anterior cervical discectomy and fusion. This condition may rapidly produce severe neurologic deficits, often requiring a prompt surgical decompression. A multilevel extension of the epidural bleeding has been rarely described after anterior cervical procedures. In such cases, the choice of the most suitable surgical approach may be challenging. Herein, we describe an effective surgical decompression of a C2-T1 ventral epidural hematoma following anterior cervical discectomy and fusion at the C5-C6 level.
By reopening the previous approach, the C5-C6 intersomatic cage was removed and the surgical field inspected for bleeding. After removal of the spinal epidural hematoma at this level, a lumbar external drainage catheter was inserted into the epidural space to perform multiple irrigations with saline solution until the washing fluid was clear.
Immediate postoperative cervical computed tomography and magnetic resonance imaging revealed grose epidural space with saline solution may be a useful technique for removal of unexposed residual blood collection, avoiding the need for posterior laminectomy or other unnecessary bone demolition.
Spinal chondrosarcomas are rare primary malignant neoplasms composed of cartilage-producing cells. They are slow-growing but locally aggressive lesions that have high rates of recurrence and progression after treatment. We provide the largest comprehensive analysis of prognostic factors, treatment modalities, and survival outcomes in patients with spinal chondrosarcoma using a large, prospectively collected national database.
Patients with diagnosis codes specific for chondrosarcoma of the spine, sacrum, and coccyx were queried from the National Cancer Database (NCDB) during 2004-2016. Outcomes were investigated using Cox univariate and multivariate regression analyses, and survival curves were generated for comparative visualization.
A total of 1843 individuals were identified with a diagnosis of chondrosarcoma, 82.1% of which were at the sacrum or coccyx and 17.9% at the spine. The mean overall survival of patients in our cohort was 7.91 years. Increased age, larger tumor, dedifferentiated histology, ved overall survival compared with those who receive lower doses. Further studies into optimal radiation modality and doses are required.We present a case of a progressive symptomatic intramedullary cyst, diagnosed decades after Lipiodol injection. Lipiodol was originally administered intrathecally for the radiologic diagnosis of spinal masses. A link between the lesion and the history of Lipiodol injection was never suspected. Surgical exploration revealed a membrane above the lesion, separating the intradural space in a cranial and caudal compartment. On the level of the cyst, we identified glassy pearls containing a fatty liquid, compatible with Lipiodol deposits. We hypothesize that the syrinx is secondary to the impact of cerebrospinal fluid pulsations on the reactive membrane and that this membrane originated from an arachnoiditis caused by Lipiodol deposits. Lipiodol was indeed abandoned after it was found to cause arachnoiditis and neurologic sequelae. Despite the cessation of its usage, the causal role of Lipiodol in arachnoiditis and spinal cyst formation should still be considered, as symptoms may arise many years after Lipiodol administration.
To evaluate the relationship between prevalence of osteoporosis and risk factors, medical costs, reoperation, and readmission in patients after spine surgery.
Patients >50 years old with thoracic or lumbar spine diseases who underwent spine surgery between 2005 and 2008 were selected from the Korean National Health Insurance Service databases for analysis. https://www.selleckchem.com/products/epz015666.html There were 147,676 patients selected, who were divided into 2 groups (osteoporosis and non-osteoporosis) and followed for 8 years. Multiple logistic regressions were performed to examine the effect of osteoporosis following spine surgery.
Patients with osteoporosis showed significant increases in readmission rates (odds ratio= 1.26, P < 0.001). Osteoporosis was found to be significantly associated with longer hospital stays and increased medical costs regardless of the cause of spine disease. For readmission, there was a 62-day difference in hospitalization time and U.S. dollars $2040 difference in medical costs between the osteoporosis group and non-osteoporosis group.
