AIM To reevaluate the Concorde position with different surgical interventions to the posterior fossa and cervical pathology and to improve patient comfort in the Concorde position through obtuse angle placement of the three-pin holder while the patient is in the supine position. MATERIAL AND METHODS Twenty-nine patients with posterior fossa pathology or cervical pathology were included in thi...

Study Design Retrospective radiologic study. Objective The sagittal alignment of the cervical spine can be evaluated using either a lateral cervical radiograph or a whole-spine lateral view on which the cervical spine is included. To our knowledge, however, no report has compared the two. The purpose of this work is to identify the difference in radiographic parameters between the cervical spin...

PURPOSE In this work a general method is presented that enables clinicians to rapidly select Rotating shield brachytherapy (RSBT) emission angles based on the patient-specific tradeoff between delivery time and tumor dose conformity. Cervical cancer cases are used as examples. METHODS Anchor plans with high dose conformity but infeasible delivery times are generated with a fine emission angle...

OBJECTIVES The correction of clinical and radiologic abnormalities in patients with symptomatic ossification of the posterior longitudinal ligament (OPLL) is the current mainstay of treatment. This study aimed to identify radiographic predictors of severity of myelopathy in patients with symptomatic OPLL. METHODS Fifty patients with symptomatic cervical OPLL were enrolled. Based on Japanese O...

BACKGROUND Reproductive health researchers are interested in finding better methods for predicting an unwanted type of delivery after induction of labor. The aim of this study was to compare the value of transvaginal ultrasonography findings and the Bishop score in predicting cesarean section after induction of labor. METHODS Two hundred women with singleton pregnancies undergoing induction o...

This article describes a method of fabricating a custom total occlusal convergence angle sticker with photo editing software and label stickers. The custom total occlusal convergence angle sticker can help clinicians achieve an accurate degree of taper during axial wall reduction of tooth preparation.

[Purpose] The purpose of this study was to assess how stretching exercise training and sling exercise training for stabilization influences the cervical spine angles and cervical range of motion of straight neck patients. [Subjects and Methods] Twenty straight neck patients were selected as subjects and they were randomly divided into two groups, the stretching and sling stabilization exercise ...

BACKGROUND Intraoperative assessment of neutral occipitocervical balance during a fusion procedure is challenging. We designed this study to introduce a more comprehensive method of evaluating the occipitocervical neutral position using lateral radiographs. METHODS One hundred neutral lateral cervical spine radiographs interpreted as normal were studied. Cervical spine radiographs were perfor...

OBJECTIVE To help elucidate the mechanism of action of the Arabin cervical pessary in pregnancies at high risk for preterm delivery. METHODS Cervical length and uterocervical angle were evaluated in relation to gestational age in 198 pregnancies not at high risk for preterm birth that underwent clinical fetal magnetic resonance imaging (MRI). Additionally, in 73 singleton pregnancies at high ...

BACKGROUND Cervical pedicle screw (CPS) insertion is a technically demanding procedure. The quantitative understanding of cervical pedicle morphology, especially the narrowest part of cervical pedicle or isthmus, would minimize the risk of catastrophic damage to surrounding neurovascular structures and improve surgical outcome. The aim of this study was to investigate morphology and quantify co...
