Filter by:The main objective of the study is to evaluate the safety, performance and clinical benefits of the Persona implant and its instrumentation in primary total knee arthroplasty
The aim of this retrospective longitudinal study was to describe a key factor in the prenatal diagnosis of isolated cleft palate on the axial transverse view, in order to provide better understanding, detection and diagnosis of this anomaly.
A clinical study designed to validate the safety and performance of the TrueLabor™ device in monitoring labor vs. current standard of care.
The purpose of the study is to determine the prevalence of tongue anomalies in a group of Egyptian children and to relate the presence of malocclusion in cases of macroglossia, tongue tie and microglossia.
The fetal CNS screening examination during the mid-trimester scan in low-risk pregnancies should include evaluation of the fetal head and spine, using transabdominal sonography. Evaluation of two axial planes allows visualization of the relevant cerebral structures to assess the anatomic integrity of the fetal brain.These planes are commonly referred to as the transventricular and transcerebellar planes. A third plane, the so-called transthalamic plane, is frequently added, mostly for the purpose of biometry. Structures that should be noted in the routine examination include the lateral ventricles, the cerebellum, the cisterna magna, and the cavum septi pellucidi (CSP). Head shape and brain texture should also be noted on these views.
The goal of this clinical trial is to test augmented reality (AR) based neuronavigation system in surgeries for patients of brain neoplasm or cerebral vascular disease. The main questions it aims to answer are: • AR based neuronavigation system can achieve accuracy that is not inferior to conventional intraoperative navigation system. Participants will participate the study after informed consent. When participants undergo surgery for their brain tumor, we will set up 2 types of neuronavigation, conventional navigation system and developed AR based neuronavigation system. Surgeon will plan and conduct surgery based on only conventional navigation system, but 3D errors at several selected points between two types of navigation will be measured and analyzed.

The aim of this retrospective study is to analyze the third molar agenesis with respect to sella turcica bridging and other craniofacial patterns in patients asking for orthodontic consultation. The main question[s] it aims to answer are: - is there a relationship between third molar agenesis and sella turchina bridging? - is there a relationship between third molar agenesis and craniofacial patterns?
The goal of this randomized controlled trial is to evaluate whether use of a pannus retractor adhesive improves fetal anatomic ultrasound examinations. The primary question it aims to answer is: • Does the use of a pannus retractor adhesive increase the rate of detailed anatomic survey completion, defined by satisfactory visualization of sixteen prespecified fetal anatomy views, for participants with a pannus and body mass index of at least 40 kg/m2?
3D modeling associated with the tracking of nerve fibers meets the needs of preoperative planning for tumors and cervico-facial congenital malformations. Indeed, these lesions are closely related to the cranial nerves and in particular nerve V (infratemporal fossa), nerve VII (temporal bone, parotido-masseter region), nerves IX, X, XI, XII and the chain cervical sympathetic (infratemporal and cervical regions). The development of a model of this region will therefore improve the surgical management of these children.
