Background of the Study: Accessory bone found in the human skull bone between squamous part of parietal and in between lambda suture is called inca bone or wormian bone .A total of 100 dried skulls were examined to know the anatomical variations of the inter parietal bone. This variants of the bones are considered as normal. This knowledge of the study very useful for the neurosurgeon, orthopedic surgeons and forensic experts for their clinical intervention.

Comprehensive Study

The lower end of humerus has numerous fossae which play a significant role during extreme movements. Coronoid fossa and olecranon fossa are separated by a delicate supratrochlear septum; occasionally septum has perforation and form an aperture, named as Supratrochlear foramen (STF). The knowledge of this foramen will be beneficial for anatomists, anthropologists, orthopedic surgeons, and radiologists. The aim of the present study was to establish the prevalence and morphometry of STF of the humerus in South Indian population and to correlate with the previous studies. The present prospective study was carried out with 274 (146 left sided + 127 right sided) dried humeri of unknown sex and age. The distal humeri were examined for the presence of STF, morphometry such as diverse shapes, vertical and horizontal diameters, and distance from STF to medial, lateral epicondyle and also to the inferior margin of trochlea using digital vernier caliper. In the present study, out of 274 dried humeri, 69 showed presence of STF, 163 were translucent and 42 were opaque. The prevalence of STF was 25.18%. After keen observation, shapes of the STF were categorized accordingly. The oval (42%) showed higher percentage whereas the other shapes showed as follows: - irregular (12%), round (19%), rectangular (12%), reniform (9.7%), sieve (7.3%) and triangular (2%). The mean vertical and transverse diameters of STF on the right side were 3.12 ± 1.09 and 5.5 ± 1.83mm and on the left side, it was 3.47± 1.32 and 4.9± 1.5mm respectively. The mean distance from STF to medial and lateral epicondyle on the right side was 25.12± 3.1 and 28.09± 2.3mm and for the left side 24.97± 2.9mm and 27.16± 2.4mm respectively. The anatomical knowledge regarding the supratrochlear foramen is much promising for the orthopaedic surgeons during intramedullary nailing for supracondylar fracture of humerus. STF appears as a radiolucent area in radiographs, which may pose a difficulty for the radiologist in differentiating it from an osteolytic or cystic lesion. In addition, STF is predominantly found in the primates, it may act an evolutionary link between the humans and lower animals.

Abstract Background and aim of the study: The clavicle is a subcutaneous bone most frequently fractured at the junction of its lateral and middle third of the shaft. Anatomical variations of the curvatures of clavicle can be of relevance for surgical correction procedures like intramedullary or internal plate fixation. The aim of the present study was to observe variations of length and medial and lateral angles of curvatures of the clavicle in a sample of South Indian population. Materials and methods: One hundred and thirteen unpaired clavicles (50 left side, 63 right side) of unknown sex and age were studied from the bone collection available at Anatomy departments of Annapoorana Medical College, Vinayaka Mission's Medical and Homeopathy Colleges, Salem. To measure the angles, Parsons method and a protractor was used. Length of the clavicle was measured with a Vernier Calipers. Observation: The average length of the clavicle was found to be 13.74cm left side and 13.76cm on the right side. The average medial angle of the clavicle on the left side is 146° and right side is147.5°. The average lateral angle on the left side is 144° and right side is 142.05°.The total average angle of the clavicle is 290.30° on left side and 289.59° on right side. Conclusion: The average length of the clavicle on the right side is more than the left side. The medial angle on the right side and the lateral angle on left side are more than corresponding opposite sides. These variations can be useful for the orthopaedic surgeons during the surgical correction procedures of clavicle fractures.

Maxillary molars contain various anatomical variations with diverse shapes and forms. The variations in root canal anatomy may be due to developmental patterns or may have a genetic influence. The root morphological studies have led to a better understanding of canal morphology that contributes to successful cleaning and shaping of the root canal system. This study was done to assess the prevalence of the number of canals in Maxillary second molars and to determine its association with age and gender in a South Indian Population by evaluating post- operative periapical radiographs. A total of 384 case sheets of root canal treated maxillary second molars were reviewed and analyzed. The patients undergoing root canal treatment for maxillary second molars were screened, and cases selected for the study were in the age group of 18- 65 years. Data was analyzed using SPSS software. Out of 384 teeth, 211 were male and 173 were female patients. Number of canals had no significant correlation with age but had significant association with gender (p=0.085). There were 3 canals in most of the cases. Within the limitations of the study, the maxillary second molars consisted mostly of 3 canals in both male and female patients. There was significant association between gender and number of canals.
