ABSTRACT
Background: Fracture of the radial head constitute 1/3rd of all the elbow fractures. It occurs as a result of a fall onan outstretched hand or a direct blow to the lateral aspect of elbow joint. This is now becoming more commondue to pre existing co-morbidities like osteoporosis and chronic osteoarthritis. Surgical correction of thecomminuted fractures of radial head involves reconstruction or replacement with artificial radial head prosthesisin cases where reconstruction is not possible.Aims and Objectives: To analyze the morphometric details of proximal end of radius and to describe themorphological features of head and bicipital tuberosity of the radius.Materials & Methodology: Sixty dry human adult radius bones of unknown age and sex were assessed formorphometric and morphological characters. Vernier caliper was used to measure the various parameters onthe proximal ends of radius bones. The data was tabulated and analyzed using SPSS software.Results: The mean length of radius was found to be 23.98 cm. Antero-posterior diameter and transverse diameterof head was 2.01 cm and 1.98 cm respectively. The height of radial head at medial end, height of radial head atlateral end, depth of articular facet and radial head circumference were 0.91 cm ,0.73 cm, 2.91 cm, 4.78 cmrespectively. The length of neck of the radius, diameter of proximal end of neck of radius, diameter of distal endof neck of radius was 1.28 cm , 1.37 cm , 1.32 cm respectively. The width of bicipital tuberocity, length of bicipitaltuberocity were 1.21 cm, 2.29 cm respectively.Conclusions: Fractures of radial head and neck are more common. Surgical management of displaced andcomminuted radial head fractures needs replacement with radial head prosthesis when reconstruction is notindicated. The results of our study are important in making anatomically and biomechanically suitable radialhead prosthesis
ABSTRACT
Introduction: Dental trauma is an irreversible pathologyand it is a commonly encountered problem in school childrenwhich after occurrence is characterized by lifelong debilitatingeffects because of physical, psychological discomfort andpain. Thus a study was conducted to assess the prevalence ofthe traumatic dental injuries to the permanent anterior teeth inrelation to occlusal relationship among 7-14 years old schoolchildren in Chitradurga townMaterial and Methods: Descriptive cross sectional studywas conducted among 3,363, 7-14 years old school childrenof Chitradurga Town. WHO (ICD-DA) 1995 Classificationwas used for assessing traumatic dental injuries and Angle’sclassification with Dewey’s Modification was used forrecording occlusal relationship. Fifteen Primary and HigherPrimary Schools and Five High schools were selected usingsimple random sampling procedure. Children aged 7-14 yearswere included in the study. Data was recorded using speciallydesigned proforma. The collected data was subjected tostatistical analysis.Results: Among 3,363 children examined prevalence rate was5.5% with higher prevalence in boys than girls. Prevalenceof traumatic dental injuries was more in the age group of10-12 years. Traumatic injuries of permanent anterior teethinvolved both maxillary and mandibular teeth with the higherprevalence in Maxillary anterior’s. Enamel fracture was thehighest (87.8%). Children with Class I type 2 and class IIdivision 1 occlusal relation exhibited very highly significantnumber of dental injuries.Conclusion: Prevalence of traumatic dental injuries wasmore in the age group of 10-12 years. Children with ClassI and class II division 1 occlusal relation exhibited veryhighly significant number of dental injuries than other type ofocclusal relationship
