ABSTRACT
Supratrochlear foramen is formed as a result of perforation of bony septum that separates olecranon fossa and coronoid fossa at the lower end of humerus. It is more common in lower animals and primates. The incidence is increasing in different human races. Aim: To study the prevalence, shape and morphometry of supratrochlear foramen in south Indian population. Methods: 156 Adult dry humeri (84 left and 72 right) irrespective of sex were studied in Department of Anatomy, Government Coimbatore medical college, Coimbatore. Presence of supratrochlear foramen was studied on the basis of its shape, size and dimensions. Also their distance from the epicondyles and lower trochlear margin were noted. Results: Out of total 156 bones studied STF was present in 43 humeri (27.5%) more common in left humeri (30.9%). Most common shape reported was oval shape in 21 humeri (48.8%). The mean transverse diameters on right and left side were 9.5 mm and 9.18 mm; while mean vertical diameters on right and left side were 6.7 mm and 6.9 mm. The mean diameter for round foramen was 4.5 and 6 mm for right and left sides respectively. The distance from the STF to medial epicondyle, lateral epicondyle and lower trochlear margin were measured and the values were tabulated. Conclusion: The knowledge of STF is important for the anatomists, orthopedicians, surgeons, radiologists and anthropologists. It is helpful for the orthopaedicians in preplanning for intramedullary nailing in supracondylar fracture of humerus.
ABSTRACT
Background: The lungs are the essential organs of respiration which are divided into lobes and fissures. Fissureshelp in a more uniform expansion of lungs. Knowledge about the fissures is helpful in appreciation of lobaranatomy and for locating bronchopulmonary segments and it is important for anatomists, pediatrician,radiologists, cardiothoracic surgeons and also for clinicians.Materials and methods: 50 spontaneously aborted fetuses were collected from labour room of Obstretrics andGynaecology Department of PSG Institute of Medical Science and Research Centre, Coimbatore and the study wasconducted in the Department of Anatomy. The morphological details of fissures and lobes of the lungs andpresence of any variation in the fissures and accessory fissure were studied.Results: Out of 50 specimens in the age group of 10 weeks to 39 weeks of gestation, the horizontal fissure wasincomplete in 35 fetuses (68%), complete in 14 fetuses (28%), absent in 1 fetus (2%) and accessory fissure wasfound in 1 fetus (2%).Conclusion: Awareness of the variations in the lobes and fissures of the lungs is important for radiologists forproper diagnosis and to surgeons for performing segmental lung resections.
ABSTRACT
Background: The human orbit is a complex anatomic region. Each of its four bony walls has its own uniquefeatures and is perforated by a number of fissures and foramina that carry important nerves and blood vessels.This is an anatomical region which is of clinical & surgical interest to many disciplines like ophthalmology, oraland maxillofocial surgery and neurosurgery. This morphometric study is undertaken to provide the normalreference values of roof and floor of the orbit in south Indian population.Materials and Methods: The study was done on 200 skulls (105 males and 95 females). The length of orbital roofand floor were measured by using manual vernier caliper. All the data obtained were tabulated and analysedstatistically by computing descriptive statistics like mean, standard deviation and range. Mann-Whitney testwas done to find out the statistical significance of all parameters of orbits, with respect to gender and side (rightand left side).Results: The results showed that the length of orbital roof and floor were significantly larger in males than infemales. There were no significant differences in between the right and left side orbits.Conclusion: This study has compared the orbital roof and floor length between the genders and between the sidesof the skulls. The prior knowledge of the orbital parameters may help to restore the normal anatomy of the orbitduring maxillofacial and reconstructive surgeries.
