The report describes the herniation of a huge migrated cervical disc, which was treated by a combined anterior approach. A 50-year-old man presented with radiculopathy and myelopathy. Radiological images revealed the herniation of a huge disc which had migrated superiorly from the C6-7 disc to the C5-6 disc. We tried to combine an anterior cervical discectomy and fusion (ACDF) and transcorporea...

The purpose of this study was to evaluate the difference between disc and condyle position between temporomandibular joints (TMJs) without disc displacement (DD) in asymptomatic volunteers, and patients who have DD in contralateral joints, respectively unilateral DD. Secondly, there were two TMJ groups which consisted of measurements from patients' symptomatic DD and volunteers with asymptomati...

OBJECTIVE To determine the response of the anterior lamina cribrosa and prelaminar tissue to acute elevation of intraocular pressure (IOP) in glaucoma patients and healthy subjects. DESIGN Prospective case-control series. PARTICIPANTS AND CONTROLS Patients with open-angle glaucoma (n = 12; mean age ± standard deviation [SD], 66.8 ± 6.0 years), age-matched healthy controls (n = 12; mean age ...

PURPOSE To investigate the effect of optic disc center displacement on retinal nerve fiber layer (RNFL) measurement determined by spectral domain optical coherence tomography (SD-OCT). METHODS The optic disc center was manipulated at 1-pixel intervals in horizontal, vertical, and diagonal directions. According to the manipulated optic disc center location, the RNFL thickness data were resampl...

PURPOSE OF THE STUDY The conservative treatment of an odontoid fracture with immobilization in a halo-vest or collar often results in pseudoarthrosis. Therefore, surgical treatment is preferred, and the Magerl-Böhler anterior osteosynthesis of the C2 dens is one of the options for achieving good bony union. The aim of this study was to show that the success of reducing an odontoid fracture is r...

Mechanisms of disc displacement in temporomandibular joint (TMJ) internal derangement (ID) in mandibular asymmetry have not been clearly defined. This study examines the degree and direction of disc displacement and their relationship with vertical asymmetry in terms of both clinical and biomechanical aspects. A retrospective study of disc displacement was performed in 31 mandibular asymmetry p...

BACKGROUND Utilizing the literature, the results of three different minimally invasive surgery (MIS) anterior cervical percutaneous operations for neck/mild radicular pain and magnetic resonance (MR)-documented "contained" (not extruded/sequestrated) discs were evaluated. Results were compared with patients treated nonsurgically for comparable/greater neurological compromise, and even more seve...

An improved computation of the load-displacement prediction for a coned disc spring is proposed. This work is an extension work of the previous proposed energy-based computation for coned disc springs. To show the validity of the improved method, the load-displacement results using the improved computation, the previous proposed method, and the finite element analyses are compared. In this work...
