Part 1: CBCT EVALUATION OF ATLANTOAXIAL/ATLANTO-OCCIPITAL JOINTS FOR CERVICAL INSTABILITY RISK ASSESSMENT

The objective of this study was to determine the potential risk for atlantoaxial/atlanto-occipital instability2 in patients who underwent cone beam computed tomography (CBCT) imaging of the head. The research was conducted at the Oral and Maxillofacial Radiology clinic of the University of Pennsylvania School of Dental Medicine (Philadelphia, PA).Materials and MethodsAfter institutional review board approval, a preliminary study was performed on patients undergoing either preimplantation assessment of jaws or evaluation of atypical facial pain, and measurements were recorded. A total of 50 CBCT volumes were identified for the selected craniocervical cephalometric measurements. Analysis of the CBCT volumes and cephalometry were performed to record various craniocervical measurements and determine the potential risk of atlantoaxial atlanto-occipital instability. The measurements were done by using the midsagittal-view CBCT images. These measurements included BAI, BDI, VAAI, and PR. It was anticipated that these measurements would provide a risk estimate for cervical instability that could potentially result in spinal cord injury. All CBCT volumes were acquired by using the Carestream CS9300 machine (Carestream, Atlanta, GA).ResultsBased on the preliminary results, the average VAAI measurement was 0.7626, the average BAI was 4.970 mm, the average BDI was 5.043 mm, and the average PR was 0.6961.DiscussionApart from VAAI, BDI, and BAI, the PR3 was uti...

Conclusions: Surgical treatment of upper thoracic spine fractures (T1-T6), although complex, is safe and effective. Reduction and fixation of these fractures decreases the risk of further neurological complications, allows for earlier mobilization, and correlates with shorter hospital LOS and improved outcomes.

Rationale: Spinal cord injuries could be catastrophic because they may result in severe neurovascular complications. Here, we present a case of thoracic spine-penetrating injury by a nail-gun. Patient concerns: A 60-year-old male presented to our emergency department with complaints of progressive right chest pain for 1 week that was preceded by back pain. He had a medical history of hypertension and denied any trauma history. He had alert consciousness and stable vital signs. He was a carpenter. Upon physical and neurological examination, no obvious wounds or vesicle formation were noted, and the patient was neurolog...

Publication date: February 2018 Source:Orthopaedics & Traumatology: Surgery & Research, Volume 104, Issue 1, Supplement Author(s): C. Mazel, L. Ajavon Thoracolumbar malunion is the result of loss of correction, insufficient correction or even no correction (both in the frontal and sagittal planes) of a thoracolumbar fracture. The main causes are incorrect assessment of the fracture's complexity (burst fracture), its potential progression to kyphosis and associated disc or ligament damage. It can also be the result of a poorly conducted initial treatment. The types of malunion have changed over the years because of...

AbstractRationale:In the treatment of noncontiguous lumbar burst fractures, there still remains controversy over proper surgical procedures.Patient concerns:A 19-year-old female patient visited our hospital after fall down from 3 m high.Diagnoses:Initial neurologic examination revealed an incomplete spinal cord injury characterized by hypoesthesia and motor grade of 2 below the L2 segment. Lumbar computed tomography and magnetic resonance imaging demonstrated L2 and L5 burst fractures severely obliterating the spinal canal.Interventions:She underwent emergent PSSPSF at L1-2-3 and L4-5-S1 following bilateral L1 and L4 lam...

Spondylolysis, Spondylolisthesis, Spondylitis &Spondylosis These four conditions affect the lumbar spine and may be confusing. What is the difference between spondylolysis, spondylolisthesis, spondylitis, and spondylosis? Spondylolysis (pars interarticularis Defect) - Used to describe the anatomic defect or break of the pars interarticularis of the vertebral arch. Spondylolysis usually occurs in the lower lumbar spine, especially the L5 vertebrae. It usually appears as a radiolucent gap on lateral X-ray. It occurs in about 5% of the population; it is not present at birth but develops over time and may run in fami...

A multidisciplinary approach is warranted to optimize outcome for both the mother and her fetus. The aim of this document is to provide the obstetric care provider with an evidence-based systematic approach to the pregnant trauma patient. Outcomes:...
