Morphology and preliminary biomechanical interpretation of mandibular sutures in Metoposaurus krasiejowensis (Temnospondyli, Stereospondyli) from the…
2019
Altres ajuts: CERCA Programme/Generalitat de Catalunya The morphology of the mandibular sutures in the Late Triassic temnospondyl Metoposaurus krasiejowensis has been examined in order to determine their role in mandible biomechanics. Until now, no histological studies of mandibular sutures in extinct vertebrates were performed, in contrast to cranial sutures. As a consequence, mandibular suture interpretations herein are based mainly on comparisons with previous studies of cranial sutures and with 3D cranial finite element analysis of this species. A total of 32 standard thin sections were studied under standard petrographic microscope observations in order to differentiate the morphology …
Personality of Fragility Fractures of the Pelvis
2017
The personality of pelvic fractures in the elderly differs in many ways from pelvic ring lesions in adults. Only high-energy trauma leads to pelvic ring disruptions. Concomitant lesions of the soft tissues occur frequently. In the elderly, low-energy falls are the rule. The most important symptom is pain, which restricts mobility. Hemodynamic instability in fragility fractures of the pelvis is rare. Emergency stabilization with pelvic binders or sheets, C-clamping or emergency external fixation are not needed. Arteriography and selective embolization is only recommended in the rare patients, who develop an active arterial bleeding due to the pelvic fracture. Especially patients, who are tre…
Cross-sectional human study of soft tissue chin (STC) thickness in adult patients in relation to sex, facial pattern and skeletal class
2017
Abstract Purpose The aim of this study was to study the relations between the soft tissue chin (STC) and sex, skeletal class, and facial pattern; and to describe the shape and behavior of the STC. Methods 385 non-growing patients were selected, 206 women and 179 men, with a mean age of 28.8 years (SD 4.2). Patients were divided into groups by skeletal class (class I, II or III) and facial pattern (brachyfacial, mesofacial or dolichofacial). STC thicknesses were measured at pogonion (Pg), soft pogonion (Pg′), gnathion (Gn), soft gnathion (Gn′), menton (Me) and soft menton (Me′) in the CBCTs. Results Sexual dimorphism was observed at Pg-Pg′ and Me-Me′. STC thickness was not related to skeleta…
Biangular fractures of the mandible
2013
Summary Introduction Bifocal fractures of the mandible often associate the angle and condyle or symphysis. Little data is available on biangular fractures. The authors had for aim to study their characteristics and to suggest an adapted management. Material and methods We retrospectively reviewed the records of patients operated on for a biangular fracture from January 2005 to December 2009. The impact of a third molar was evaluated using Pell and Gregory's and Shiller's classifications. Results Six hundred and forty patients underwent surgery for a mandibular fracture, seven of whom (1.1%) for biangular fractures. The patients’ mean age was 27.6 years. Patients were predominantly men (85.7…
Radiological analysis, operative management and functional outcome of open book pelvic lesions: a 13-year cohort study.
2011
Abstract We present the clinical and radiological outcome of a 13-year cohort study of 38 open book pelvic lesions. All patients were treated in one Level I Trauma centre. In the posterior pelvis, sacro-iliac diastasis was seen in 31 patients, sacral fracture in 7. In all patients with sacro-iliac diastasis, the pubic bone was inferiorly displaced on the primary ap pelvic overview on the side of injury. All but one patient was treated with open reduction and internal fixation of the symphysis pubis. Additional stabilization of the posterior pelvis was done in 9 patients. 32 patients were seen after a median follow up of 84 months. Majeed score and SF-36 questionnaire were used. Functional o…
Internal Fixation in Postpartum Symphysis Pubis Rupture: Report of Three Cases
1997
We present three patients with postpartum symphysis pubis rupture whose severe complaints persisted after conservative treatment. All three ruptures were stabilized with open reduction and internal fixation. There were no postoperative problems, and implants were removed after a mean period of six months. Patients were free of complaints after implant removal. In select cases, operative treatment of postpartum symphysiolysis may be indicated.
Modified LEAD System distractor to prevent tilting during alveolar distraction in the mandibular symphyseal region
2006
This report describes a simple modification of the LEAD System distractor that prevents tilting of the distractor rod, and consequent deviation of distraction direction, during alveolar distraction in the mandibular symphysis region.
Versatility of nasolabial flaps in oral cavity reconstructions
2014
Objectives: Describe the techniques involved and the results obtained witn nasolabial flaps in small and medium- sized defects of the oral cavity. The procedure is an easy resconstructive option with a high success rate and with very good aesthetic and functional outcomes. Study Design: A retrospective analysis of 16 nasolabial flap reconstructions in 15 oncological patients with oral cavity defects undergoing single-stage surgical interventions. We evaluate the tumor type, its location, size, the resective and reconstructive techniques involved, as well as any complications. Results: Out of 15 patients, 9 were male and 6 female, with ages ranging from 60-85 years. The primary tumor was loc…
La pubalgia nello sportivo: quadri RM di “Osteite Pubica"
2005
La pubalgia è una sindrome dolorosa, a volte a carattere invalidante, che colpisce sia gli sportivi agonisti che quelli amatoriali, rappresenta il 2-5% delle patologie correlate all’attività sportiva agonistica e non sempre le sue cause sono facilmente diagnosticabili. L’osteite pubica rappresenta una delle principali cause di dolore inguinale e colpisce gli sportivi nel 0,5-0,7% dei casi. Dal settembre 2003 all’agosto 2004, 40 atleti, 37 uomini e 3 donne (età compresa tra 18 e 37 anni; età media: 24 anni), con diagnosi clinica di pubalgia sono stati sottoposti a RM del bacino. In tutti i casi la sintomatologia era caratterizzata da dolore mono (33%) o bilaterale (67%) con irradiazione alla…
