The authors undertook a prospective study to evaluate the influence that the anatomical dimensions of the ramus of the mandible and the presence of lower third molar teeth may have on the sagittal split ramus osteotomy. The anatomical dimensions measured included the width of the anterior mandibular ramus, the height of the corpus posterior to the second mandibular molar and the antero-posterio...

OBJECTIVE To assess whether patients with a fracture of the high superior pubic ramus have functional outcomes worse than those of the lower or more central superior pubic ramus. METHOD We carried out a retrospective cohort study of all patients with pubic ramus fractures seen in either the emergency department or outpatient clinic of a level-1 trauma centre in Montreal. Patients were grouped...

BACKGROUND AND PURPOSE Lumbar zypapophyseal joints are innervated by the medial branch of the posterior lumbar ramus. The aim of this work was to describe the precise course of the medial ramus on axial CT scans and to define a precise location for its selective infiltration. METHODS Lumbar spines of two cadavers were first dissected to assess the route of the L1-L5 posterior ramus. Thirty lu...

UNLABELLED The purpose of this manuscript was to assess mandibular ramus block grafts used for augmentation of mandibular posterior segments, followed by subsequent implant placement. Twenty-four human subjects in need of lateral ridge mandibular augmentation were included in the current patient series. INCLUSION CRITERIA recipient site had at least 10-mm residual height, but less than 4.3-mm...

Aim. The present study aims at exemplifying the incidence, and aetiology and analyses the outcomes of open reduction internal fixation (ORIF) over closed treatment of mandibular ramus fractures. Patients and Method. In the present retrospective analysis of mandibular fracture patients, variables analysed were age, sex, cause of injury, pretreatment occlusion, treatment given, period of maxillo-...

PURPOSE The purpose of this study was to evaluate changes in the mandibular canal and ramus morphology before and after a sagittal split ramus osteotomy. PATIENTS AND METHODS The subjects were 30 patients (60 sides) with mandibular prognathism who had undergone bilateral sagittal split ramus osteotomy setback surgery. The mandibular canal position and ramus morphology were measured at the 3 h...

The absolute and relative breadths of the mandibular ramus (MRB) display substantial variation in modern humans, and are of analytical value in paleoanthropology. According to Enlow et al. ([1969] Am. J. Orthod. 56:6-23), the ramus is the growth counterpart of the middle cranial fossa (MCF) and the pharynx. Such counterpart principles state that variation in ramus breadth is a frequent function...

At the Specialty Clinics of Georgia we have been evaluating the comparative efficacy of the Gray Ramus Communicans Nerve Block for the treatment of painful osteoporotic vertebral compression fracture. The relative frequency of Thoracic and Lumbar fractures being equal, we began to ask the question why was the utilization of the Gray Ramus Communicans Nerve Block more frequent for a lumbar verte...

Myxofibroma is a rare tumor. Three cases of myxofibroma, each of which developed at the right mandibular ramus, mandibular anterior tooth region, are presented. Myxofibroma developing in the mandibular ramus region is rare, and there has been only one case reported so far in Japan.
