RESUMEN
Introduction: Upper end of tibia is the component of knee joint. Accurate morphometric anatomical data of theupper end of tibia and morphometric differences according to gender are very important to make design of totalknee joint replacement prosthesis. Knee prosthesis made based on morphometric data of components of knee(femur and tibia) and according to gender difference will give better results after surgery in early mobility ofpatients as well as fewer post-operative complications.Aim: Present study was done to find out sexual dimorphism in upper end of tibia as well as differences inmorphometric data of upper end of tibia between other populations across the world and within India.Materials and Methods: For the present study the material consisted of 120 dry tibia of known gender were used.Out of them 60 were of male tibia (30 of right side and 30 of left side) and 60 were of female tibia (30 of right sideand 30 of left side). We have selected five metrical parameters 1. Bicondylar width (BCW), 2. Medial condylarantero-posterior distance of superior articular surface (MCAPD), 3. Lateral condylar antero-posterior distanceof superior articular surface (LCAPD), 4. Medial condylar transverse distance of superior articular surface(MCTD) and 5. Lateral condylar transverse distance of superior articular surface (LCTD) for the present studybased on which the tibial component of prosthesis for knee joint replacement surgery is made.Results: All five parameters which are chosen are found significantly larger in male than females. The findingsare smaller than Caucasian population and population of North India and found larger than population of SouthIndia.Conclusion: Present study provides data of measurement of upper end of tibia by direct observation which will beuseful to select correct sized knee prosthesis according to measurements. We have also provided data genderwise and on right and left side which will improve the longitivity of knee prosthesis, increased mobility of patientand improve the lifestyle after knee replacement surgery.
RESUMEN
Background & Objectives: will be useful for anatomists, anthropologists, aneasthetist, orthopedics and experts in the field of forensic medicine. The aim of the study was to examine the different morphometric variations of the human mandibles and comparing between dentate and edentulous mandibles is done. Methods: This study included only bone who exhibited no obvious bone pathology. All measurements were done bilaterally, performed with a stainless steel metric digital calliper with 0.01 mm precision. The relative position of the Mental foramena (MF)as analyzed with measurements made from nferior wall of mandible to the mandibular base, from anterior wall of mandible to the mandibular skeletal midline, from his posterior wall to the posterior mandibular rim. To determine this relation, the standard horizontal plane defined by Morrant was used. Briefly, the mandible was placed on a horizontal surface, to which the lower border of the mandible comes into greatest contact when vertical pressure is applied to the second molar teeth. Results: The most common location for the MF is a position aligned between second premolar and first molar (Rt. side 30% & Lt. Side 31%). Comparison of measurements of dentate and edentulous mandible is significnat on both sides. Conclusion: The knowledge of the distances from surgically encountered anatomical landmarks in the present study provide valuable information to dental surgeons that will facilitate effective localization of the neurovascular bundle passing through mental foramen thus avoiding complications from local anesthetic, surgical and other invasive procedures.
RESUMEN
Introduction: Arcuate foramen is less known trait of the human atlas vertebra formed by a delicate bony spiculum, which arches backward from the posterior end of the superior articular process. Method: Examination of 100 human atlas vertebra done. Result: Study revealed that the trait was present in 13% of the samples. The mean length of the arcuate foramen form was 7.16 mm on the left side and 9.99 mm on the right side in bilateral positive samples while it was 8.14 mm and 9.26 mm respectively in unilateral positive samples. The mean vertical height of this foramen was 6.57 mm on the left side and 6.52 mm on the right side in bilateral positive samples while it was 4.91 mm and 5.38 mm respectively in unilateral positive samples. The sides did not show any statistical significant differences. Conclusion: The importance of the arcuate foramen lies in the external pressure it may cause on the vertebral artery as it passes from the foramen transversaium of the first cervical vertebra to the foramen magnum of the skull.
RESUMEN
Background And Objectives: The study has been done to find out correlation between different parameters of foot. The aim and objective are to develop a model to reconstruct a stature from foot breadth. The study is carried out in 285 asymptomatic healthy adults 149 Males and 136 Females between 18-23 years of age, belongs to different region of Gujarat. Materials And Methods: Foot breadth and foot length were measured with sliding calliper and stature was measured by a standard anthropometer rod in erect anatomical position. Observation And Results: Obtained data was statistically analysed, and a significant correlation of stature was observed with foot breadth and foot length with foot breadth on both Rt. And Lt. side in males and females. Linear regression equations were derived to calculate foot length and stature from foot breadth. Interpretation And Conclusion: A highly significant correlation coefficient (p-value 0.0000) has been found between different parameters of foot on both Rt. and Lt.side in males and females. So stature can be more accurately calculated by foot breadth than long bones. The findings are useful to anatomists, criminologists, human biologist and forensic medicine experts.
RESUMEN
Sacrum is a large triangular bone. It is formed by fusion of five sacral vertebrae and forms the caudal region of the vertebral column. It forms posterosuperior wall of the pelvic cavity wedged between the two hip bones. The present study is undertaken to test the validity of the parameters by which it may be possible to know detail morphometry of sacrum and sacral hiatus. The material for the present study consists of 150 adult sacrum of unknown sex. The measuring was done on intact parts of normal bones. Bones showing wear and tear, fracture or any pathology were not considered. Each linear recording was taken to the nearest millimeter. shape and length of the sacral hiatus, level of apex and anteroposterior depth at apex, level of base and transverse width at base were measured with the help of vernier calipers, recorded, tabulated and analyzed. Significant findings in the present study are high, 83 (55.33%) bones showed narrowed sacral canal at the apex (0-3mm), where as previous studies reported 15.6%. This should be kept in mind while applying caudal epidural anaesthesia in Gujarati population.
RESUMEN
The distinctive morphology of human skeleton and its clear sexual dimorphism make it of interests from anatomical, forensic, obstetrical, radiological and anthropological point of view. 100 known sex normal dry human hip bones obtained from Medical College Bhavnagar, 168 known sex normal dry human hip bones from BJ Medical College, Ahmedabad and Smt. NHL Municipal Medical College, Ahmedabad were studied the year of 2005-06. The posterior segment of Greater Sciatic Notch, Genoves’ sciatic notch index and posterior angle are found to be significant by t test (P < 0.001). The posterior angle of greater sciatic notch was found to be highly significant for determination of sex of hip bone.
RESUMEN
Mandibular canines exhibit the greatest sexual dimorphism amongst all teeth. The present study was performed on 368 healthy MBBS students of Medical College, Bhavnagar (216 males, 152 females) of 18 – 24 years with the aim to investigate whether any correlation existed between odontometric measures including mandibular canine index, and sex determination in the year of 2006. Mean value of intercanine distance was higher in males than females and the difference was statistically highly significant (p value<0.01). Comparison of mean values of left and right mandibular canine widths exhibited lesser values in females. The variation in right and left mandibular canine width between males and females was highly significant (p value<0.01). The right and left mandibular canine index (MCI) among genders showed significant difference. Our study conclusively establishes the existence of a definite statistically significant sexual dimorphism in mandibular canines and MCI.
RESUMEN
The pterion is a commonly used landmark on neurocranium; classified in four types: sphenoparietal, frontotemporal, stellate and epipteric. In this study we have found out morphology and location of pterion of skull of Gujarat region and comparison of their morphology with other populations. 42 skulls of unknown gender were examined on both sides from Department of Anatomy, Medical College Bhavnagar. Measurements of the location of the pterion were made by using stainless steel callipers. Sphenoparietal was the most common form comprising 91.7%. Measurements between from center of pterion to posterior end of frontozygomatic suture, vertical distance to upper margin of zygomatic arch, horizontal distance to lateral margin of optic canal and horizontal distance to outer end of the sphenoid ridge on the lesser wing of the sphenoid were taken. Anatomical variations of the pterion, which are of interest to anthropologists, forensic pathologists and surgeons, deserve further investigation in other populations from different areas.
RESUMEN
The role of carrying angle in the sex determination and its cause of formation is a long debated issue in Anatomy and Anthropology. Most studies have focused on the question of cause of formation of carrying angle, difference in sex and age but little attention has been given to correlate the carrying angle with various parameters. Hence, an effort has been made to find out correlation of carrying angle with height, and length of forearm. For present study, total 333 (173 female & 160 male) asymptomatic, healthy students of Nursing School, Homeopathic Medical College, Ayurvedic College and Medical College belonging to various regions of Gujarat were selected. There ages ranged between 17 to 22 years. An improvised instrument goniometer was used for measurement of carrying angle. Height was measured in standing, erect, anatomical position from vertex to heel with bare foot. Vernier caliper of 12” was used to measure the length of forearm. According to the present study, height and length of forearm of the person are inversely related with the carrying angle. Greater carrying angle in female is considered as secondary sex characteristic. Knowledge of the carrying angle helps in paediatric elbow surgery. It also helps orthopedic surgeon for correction of cubitus varus deformity occurring after malunited supracondylar fracture of humerus.
RESUMEN
The purpose of this study was to estimate the average angle of femoral neck anteversion in an Indian population. Unpaired 92 dry femurs, 50 of female (27 right and 23 left) and 42 of male (22 right and 20 left) devoid of any gross pathology were used to measure the femoral neck angle (FNA) from Department of Anatomy, Govt. Medical College, Bhavnagar in year 2005. They were evaluated by the Kingsley Olmsted method, and the data were statistically analyzed. In female femoral neck anteversion range form –8.3° to +30.4º with a mean of 16.4º on left and 10.5º on right sides. In male femoral neck anteversion range from –13.7° to +25.6º with a mean of 14.3º on right and 7.2º on left sides. The female femora showed about 2.7° more anteversion than the male femora. The average left-sided femora showed about 6.4° more anteversion than the right-sided femora.
