diameter and 6.6 cm (5cm-8cm) anteroposteriorly. The human heart was trapezoidal in shape. The pig heart, in contrast, was a broad cone shaped organ. In humans, the left atrium received the four pulmonary veins whereas in pig it received two pulmonary veins. In right atrium of man, orifices of superior and inferior caval veins were in a direct line whereas in pig veins opened at right angles to each other. The present study suggests that the morphology of human and porcine heart is almost similar with significant anatomical differences between porcine and human hearts that might effect the success of the cardiac xenograft within the human recipient.
The knowledge of anatomy of the heart has evolved over the ages and has contributed to the applications of cardio thoracic surgery and in understanding physiology of the various heart related diseases. In this study an attempt has been made to study the anatomy of pulmonary valve in human cadaveric hearts. The anatomy of pulmonary valve was studied by gross examination and dissection of hearts. The range of various parameters along with mean value and standard deviation was calculated. The annular length of the pulmonary valve was in the range of 5.4-7.8 cm with mean of 6.5 ± 0.59 cm. The width of right anterior, left anterior and of posterior leaflet was in the range of 1.9-3.1 cm with mean of 2.4 ± 0.35, 1.8-3.4 cm with mean of 2.5 ± 0.45 and 2.1-3.5 cm with mean of 2.7 ± 0.4 respectively. As a result of such studies, current notions may be so changed and extended so as to understand the better morphologic structures of the heart and to provide a scientific basis for its function.
Aim: The purpose of our study was to do a morphometric analysis of talus and calcaneum along with the pattern of articular facets on the surface to facilitate orthopedicians in planning surgeries for subtalar implants and foot prostheses.
Materials and Methods: For the study, 60 dry adult human tali(24 left and 26 right) and 60 dry calcanei(30 left and 30 right) were obtained from the Department of Anatomy.The tali and calcanei were looked for number and type of articular facets on their surface. The morphometry of talus and calcaneus was done using a digital caliper accurate to 0.01 mm and data recorded.
Results: The most common type of articular facet on tali and calcanei in the North Indian population studied was type B. The anteroposterior length and transverse width of the left tali were: 50.89 mm and 37.84 mm, respectively and of right tali were: 51.14 mm and 37.9 mm, respectively. The width, length and depth of left and right sulcus tali were: 6.75mm, 18.7 mm and 5.05 ± 0.33mm, and 7.13 mm, 18.21 mm and 5.44mm, respectively. For left and right calcanei, anteroposterior length and transverse width were: 70.61 mm and 40.1mm, and 71.02 mm and 41.48mm, respectively. The width, length and depth of left and right sulcus calcanei were: 6.08 mm, 46.52 mm and 3.78 mm and 5.34 mm, 45.91 mm and 3.81 mm.
Conclusion: Our study will be helpful as a vital tool for reconstruction surgeries of hindfoot deformities and foot reconstruction procedures.
Background: Morphometry of talus will be helpful for radiologists, orthopaedicians and surgeons for diagnosis and treatment of talar fractures and making bone prosthesis.
Aims and Objectives: The purpose of our study is to do a morphometric analysis of talus to facilitate orthopedicians in planning surgeries for subtalar implants and foot prostheses. This will be of great use to forensic anthropologists.
Materials and Methods: For the study, 60 dry adult human tali (24 left and 26 right) were obtained from the Department of Anatomy, SGT Medical College, Budhera. The morphometry of talar surfaces was done using a digital caliper accurate to 0.01 mm and data was recorded.
Results: The mean values of medial, central and lateral length on the trochlear surface were 27.0cm, 28.1cm, 27.4cm on right side and 29.4cm, 27.0cm, 29.1cm on left side. Mean anterior, central and posterior widths on the trochlear surface were 27.6cm, 26.2cm, 21.1cm on right side and 27.0cm, 24.0cm, 23.1cm on left side. The mean central height and width on the lateral articular surface was 26.2 cm and 21.9 cm on the right side respectively and 23.0 cm and 16.8 cm on the left side respectively. The mean central height and central width on the medial articular surface was 13.6 cm and 25.9 cm on the right side respectively and 10.8cm and 17.9 cm on the left side respectively.
Conclusions: The current study would be helpful as an important tool for reconstruction surgeries of hindfoot deformities and foot reconstruction procedures. Also it would be useful to orthopaedicians to design accurate talus bone prosthesis and talar implants. Morphometry of talus will be of use in objective categorization and racedetermination for forensic purposes.
