Evaluation of Mandibular Incisive Canal using Cone Beam Computed Tomography in Malaysians
This study was aimed to estimate the length of the MIC in the interforaminal safe zone, to analyse its course in relation to the lingual and the buccal cortical plates of the mandible using cone beam computed tomography (CBCT) scans and to relate the above findings to age, gender, dental status and Malaysian races.MethodsRetrospective analysis of 100 CBCT scans (n = 200) was performed on both sides of the mandible. Cross-sectional and panoramic images were reconstructed. The length of the MIC and the horizontal distances between the MIC and the buccal and the lingual cortical plates were measured at the three different points (starting, mid-, end points) . Independent samples t-test and one-way ANOVA test were used to analyse the variation in the length and course of the MIC in gender, age, dental status and Malaysian races.ResultsThe mean length of the MIC was 11.31 ± 2.65 mm, with the Malays having the longest MIC, followed by the Chinese and the Indians (p
Abstract Treatment of pilon fractures remains challenging due to the difficulty of fracture reduction and associated soft tissue complications. The aim of this study was to evaluate the pitfalls and strategies of posterior column reduction in the treatment of complex tibial pilon fractures (AO/OTA 43-C3). Thirteen AO/OTA classification 43-C3 type pilon fractures treated between January 2013 and January 2016 were retrospectively analyzed. Nine cases were treated by external fixation within 26 hours (range, 6-56 hours) after injury. The definitive open reduction and internal fixation (ORIF) was performed after the w...
ConclusionsFixation for cervical instability is a critical component of the management of DS. A minority of patients receiving surgery were identified through asymptomatic screening. There was a high complication risk associated with surgery in our study; however, the addition of rigid fixation has lessened the complication rate compared with previous studies.Level of EvidenceLevel IV.
CONCLUSION: An anatomically contoured provisional restoration may provide a strategy to stimulate peri-implant soft tissue healing, minimize loss of buccal bone plate at the marginal level, and maintain pristine volume in the alveolar bone better than noncustomized restorations.

We report the case of a neonate, who presented with increasing respiratory distress and an abnormal chest radiograph, initially assumed as pneumonic changes. A revised diagnosis of CPAM was made after a chest computed tomography (CT) scan. The neonate subsequently had a successful excision of the affected lobe with remarkable clinical improvement. The case highlights the need to utilize superior imaging studies such as CT when plain radiographs are inconclusive.
This study aimed to analyze cervical alignment after single-level ACCF using autologous bone graft without spinal instrumentation for CPS compared with that for CDD.MethodsSix patients underwent single-level ACCF using autologous bone graft without spinal instrumentation for CPS. The control group included 18 age-matched patients who underwent single-level ACCF using autologous bone graft for CDD without spinal instrumentation for the same duration. Cervical and lateral plain radiographs and computed tomography scans were taken. The Frankel classification was used to assess the neurological status preoperatively, postopera...
Authors: Barbier NF, De Wouters S, Traore SY, Tran Duy K, Docquier PL Abstract Malunion in cubitus varus most often results from inadequate supracondylar fracture reduction or from secondary displacement. Treatment of cubitus varus needs an accurate preoperative planning to obtain a good functional and esthetical outcome. Planning based on conventional radiology is source of inaccuracy and clinical results are variable. Developments of computer-assisted orthopaedic surgery (CAOS) and of patient specific instruments (PSI) have made accurate three dimensional (3D) preoperative simulation possible. This original techn...
The aim of this paper is to evaluate contrast media (CM) bolus geometry and opacification patterns in the coronary arteries with particular focus on patient, scanner and safety considerations during coronary computed tomography angiography (CCTA).
ConclusionOur results demonstrate that bedside thoracic US is characterized by a very good accuracy in the diagnostic work-up of major trauma patients, even in difficult conditions, allowing rapid diagnosis of PNX.Advances in knowledgeThe novelty of this research lies in the possibility of diagnosing potential life-threatening conditions in a very short time by means of US, thus proposing a revision of the Advanced Trauma Life Support (ATLS) guidelines in order to incorporate it in the work-up of high-energy injured patients.
ConclusionIn cases of OGIB, superselective mesenteric angiography (SSMA) with intraoperative methylene blue injection can be used as an adjunct to routine diagnostic modalities to guide surgical interventions for controlling hemorrhage and for limiting the extent of bowel resection.

Toledo de Araujo, Renato Locks, Diego Pinheiro AguiarAbstractIntroductionThe aim of the study was to evaluate femoral torsion (FT) by computed tomography (CT) in young patients with hip pain and femoroacetabular impingement (FAI) in a Brazilian population. After the diagnosis of impingement, the complete analysis from the hip biomechanics and morphology has become essential.MethodsForty-one patients from 18 to 45 years presenting hip pain without arthrosis (Tönnis
