Radiological and clinical associations with scoliosis outcomes after posterior fossa decompression in patients with Chiari malformation and syrinx from the Park-Reeves Syringomyelia Research Consortium

Jennifer M. Strahle, Rukayat Taiwo, Christine Averill, James Torner, Jordan I. Gewirtz, Chevis N. Shannon, Christopher M. Bonfield, Gerald F. Tuite, Tammy Bethel-Anderson, Richard C. E. Anderson, Michael P. Kelly, Joshua S. Shimony, Ralph G. Dacey Jr., Matthew D. Smyth, Tae Sung Park, David D. Limbrick Jr., and for the Park-Reeves Syringomyelia Research Consortium

, examination findings, and operative parameters. Review of radiographs and MR images for these patients identified 251 with scoliosis present at the time of their CM-I diagnosis, with scoliosis defined as a coronal curve of at least 10°. Curves were measured according to the guidelines from the Spinal Deformity Study Group’s Radiographic Measurement Manual by O’Brien et al. 21 Of these, 41 patients underwent PFD and had at least 1 follow-up image with a mean interval of 2 years before undergoing spinal fusion. Demographic information analyzed for an association with

Complications in ambulatory pediatric patients with nonidiopathic spinal deformity undergoing fusion to the pelvis using the sacral-alar-iliac technique within 2 years of surgery

Richard Menger, Paul J. Park, Elise C. Bixby, Gerard Marciano, Meghan Cerpa, David Roye, Benjamin D. Roye, Michael Vitale, and Lawrence Lenke

. Operative complications were queried from the clinical record, including hardware prominence, durotomy, pain, weakness, deep wound infection (DWI) below the fascia, seroma, and PJK or PJF. PJK was defined as a sagittal proximal junctional angle from the caudal endplate of the UIV to the cephalad endplate of UIV+2 ≥ 10° and/or a change ≥ 10° compared with the preoperative condition. Preoperative and postoperative motor strength examination findings were obtained during retrospective chart review. Radiographic measurements were obtained, including pelvic parameters

Resection of congenital hemivertebra in pediatric scoliosis: the experience of a two-specialty surgical team

Elise C. Bixby, Kira Skaggs, Gerard F. Marciano, Matthew E. Simhon, Richard P. Menger, Richard C. E. Anderson, and Michael G. Vitale

, levels of fusion, anesthesia time, OT, EBL, and use of navigation, were collected from the anesthesia and operative reports. Operative reports were reviewed for neuromonitoring changes and other intraoperative complications, and all subsequent clinical follow-up notes were reviewed for postoperative complications. Radiographic measurements were obtained from scoliosis radiographs obtained just prior to surgery, radiographs taken postoperatively prior to discharge, and the most recent, available radiographs. Surgical Technique The surgical team consisted of an

Computed tomography–generated anthropometric measurements of orbital relationships in normal infants and children

Garrett M. Pool, Ryne A. Didier, Dianna Bardo, Nathan R. Selden, and Anna A. Kuang

data have been generated by direct measurement (anthropometrics) and/or radiographic measurement (cephalometrics) of orbital anatomical characteristics and have more recently included ultrasound measurements of fetuses in utero. 34 Anthropometric measurements have generated a large database of normal values based on surface measurements, in which relatively thin soft tissues overlie bony surfaces, allowing for accurate measurement without the use of ionizing radiation. 20 Anthropometric measurements, however, are subject to inter- and intraobserver variability

Residual thoracolumbar/lumbar curve is related to self-image after posterior spinal fusion for Lenke 1 and 2 curves in adolescent idiopathic scoliosis patients

postoperative SRS-22r self-image scores. ATR was measured with a scoliometer. Radiographic parameters included MT and TL/L curve Cobb angle, MT curve apical vertebral translation (AVT), T5–12 kyphotic angle, and clavicular angle (absolute value). Lenke type was 1A in 38 patients, 1B in 12 patients, 1C in 19 patients, 2A in 13 patients, 2B in 3 patients, and 2C in 1 patient. All radiographic measurements were performed by a trained orthopedic surgeon who was uninvolved in the surgeries. Univariate and multivariate general linear models were employed to identify factors

Analysis of the growth pattern of a dermoid cyst

Case report

evidence of hair and fat within the lesion. Postoperative Course Immediate postoperative MRI revealed complete resection without evidence of residual lesion. The final pathological analysis was consistent with a dermoid cyst. The total length of the resected specimen was about 70 mm, although the cyst itself, which was dark red in color, was approximately 55 mm in length ( Fig. 6 ). These findings were consistent with our aforementioned radiographic measurements. The patient had an unremarkable postoperative course and was discharged home on the 5th day after

There is no consensus on the definition of instability that warrants surgical intervention 6 , 29 , 31 because of variability in the different radiographic measurements, different surgical indications and techniques, and limited

Cervical lordotic alignment following posterior spinal fusion for adolescent idiopathic scoliosis: reciprocal changes and risk factors for malalignment

cranial end-plates of L-1 and S-1. The C-7 sagittal vertical axis (SVA) was defined as the horizontal distance from the superior posterior end of the upper sacral endplate to the C-7 or C-2 plumb lines. The CLA, TK, LL, and SVA were measured immediately before surgery, 2 weeks after surgery, and 2 years after surgery. Each measurement is shown in Fig. 2 . Two independent spine surgeons (K.H. and H.T.) performed the radiographic measurements; the mean values of the measurements were then used for further analyses. The kappa coefficient of interrater reliability for CLA

-cassette standing radiographs. The radiographic measurements were done by 2 independent spinal surgeons, and the mean values were used for the analysis. The Scoliosis Research Society (SRS)–22 questionnaire was taken by patients before surgery and at the last follow-up; these scores served as clinical outcomes, which included subscores of 5 domains (pain, appearance, mental health, activity, and satisfaction) and a total score. Statistical Analysis Data were analyzed using SPSS statistical software (version 19.0; IBM SPSS Statistics) and expressed as the mean ± SD. The Pearson

Patient and operative factors associated with complications following adolescent idiopathic scoliosis surgery: an analysis of 36,335 patients from the Nationwide Inpatient Sample

through a procedural code, it is unclear whether the code corresponded to a Smith-Petersen osteotomy, Ponte osteotomy, pedicle subtraction osteotomy, or vertebral column resection. Given that the NIS is not specific to spine surgery, other parameters such as radiographic measurements, curve types, neurological status, and long-term results are not available. Lastly, the NIS contains only inpatient data, meaning that complications, including deaths, occurring after discharge are not captured. In the future, prospective investigations should help to better delineate the
