Unilateral lumbosacral facet joint dislocation without associated fracture

JOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 2 2004
Ranald M Stuart
Summary In the lumbosacral spine, unilateral facet joint dislocation is an infrequent injury, which is often associated with fractures at the involved or other lumbar levels. The rare occurrence of unilateral lumbosacral facet joint dislocation without any associated fractures is presented with CT and MRI, and surgical correlation. To our knowledge, cross-sectional imaging of this injury has not previously been described in the published literature. [source]

Alpha 1 antitrypsin deficiency alleles are associated with joint dislocation and scoliosis in Williams syndrome,

AMERICAN JOURNAL OF MEDICAL GENETICS, Issue 2 2010
Colleen A. Morris
Abstract Elastin haploinsufficiency is responsible for a significant portion of the Williams syndrome (WS) phenotype including hoarse voice, supravalvar aortic stenosis (SVAS), hernias, diverticuli of bowel and bladder, soft skin, and joint abnormalities. All of the connective tissue signs and symptoms are variable in the WS population, but few factors other than age and gender are known to influence the phenotype. We examined a cohort of 205 individuals with WS for mutations in SERPINA1, the gene that encodes alpha-1-antitrypsin (AAT), the inhibitor of elastase. Individuals with classic WS deletions and SERPINA1 genotypes PiMS or PiMZ were more likely than those with a SERPINA1 PiMM genotype to have joint dislocation or scoliosis. However, carrier status for AAT deficiency was not correlated with presence of inguinal hernia or with presence or severity of SVAS. These findings suggest that genes important in elastin metabolism are candidates for variability in the connective tissue abnormalities in WS. © 2010 Wiley-Liss, Inc. [source]

Etomidate for Pediatric Sedation Prior to Fracture Reduction

ACADEMIC EMERGENCY MEDICINE, Issue 1 2001
Richard Dickinson MD
Abstract. Objective: While etomidate is reported as a procedural sedative in adults, its use in children has not been extensively reported. The authors describe their experience with etomidate for procedural sedation in children with extremity fractures and major joint dislocations. Methods: This was a retrospective descriptive chart review. The setting was a university-based emergency department (ED) that follows national guidelines for procedural sedation. Subjects were children less than 18 years old who received etomidate prior to fracture reduction or major joint dislocations. Standardized data were abstracted from the medical records, including patient demographics, diagnosis, weight, types and doses of sedative and analgesic agents used, number of boluses of etomidate, attempts at reduction, complications encountered, vitals signs before, during, and after the reduction, disposition, and the time from procedure to discharge. Descriptive statistics calculated included means and proportions with 95% confidence intervals. Results: Fifty-three children received etomidate for fracture reduction. Their mean age was 9.7; 41.5% were females. Indications for reduction included forearm fractures (38), ankle fractures (12), upper arm fractures (2), and hip dislocations (1). In most cases (83%) reduction was successful after one attempt only. The mean initial and total doses of etomidate were 0.20 mg/kg (range, 0.1 to 0.4) and 0.24 mg/kg (range, 0.13 to 0.52), respectively. Thirteen patients required a second bolus of etomidate or midazolam. Thirty-four patients (64%) were discharged from the ED after a mean observation of 94 minutes (range, 35 to 255). There were no major adverse events (95% CI = 0% to 5.7%). One patient reported nausea and one required a fluid bolus for hypotension. One patient receiving multiple sedatives and opioid analgesics was admitted for observation due to prolonged sedation. No patient required assisted ventilation or intubation. Conclusions: These results suggest that etomidate is a safe and effective agent for procedural sedation in children requiring fracture and major joint reductions. [source]
