Role Of Greater Sciatic Notch In Sex Determination

Context:The sciatic notch has been widely used as a sexing criterion in modern humans. Aims:To study characteristic of sciatic notch in 59 no. of hip bones Bhopal region. Settings and Design:was a cross sectional study conducted on 59 hip bones (Male=30, female=29) Statistical analysis used: Unpaired t test using Graph Pad Prism software. Results:There was significant difference seen between males and females in all parameters. Differences were very significant for length of posterior segment of greater sciatic notch and posterior angle of greater sciatic notch. Conclusions: Greater sciatic notch can be used in sex determination. Length of posterior segment of greater sciatic notch and posterior angle of greater sciatic notch are considered to be better parameters.

Normal and variant origin and branching pattern of inferior phrenic arteries and their clinical implications: a cadaveric study.

Background: Inferior phrenic arteries, which constitute the chief arterial supply to the diaphragm, are generally the branches of abdominal aorta, however, variations in their mode of origin is not uncommon. Very less information is available regarding the functional anatomy of the inferior phrenic artery in anatomy textbooks. Methods: The present study was conducted utilizing 36 formaline-fixed cadavers between 22 years to 80 years over a period of 5 years. The frequency and anatomical pattern of the origin of the right and left inferior phrenic arteries were studied. Results: On the right side, the inferior phrenic artery arose independently from abdominal aorta in 94.4% cases and on the left side in 97.2% cases.Other sources of origin were seen in 5.55% cases. Left hepatic artery was seen as the source of origin for right inferior phrenic artery in one case while in second case left gastric artery was the source for both the right and left inferior phrenic artery. The right inferior phrenic artery is the most common source of collateral arterial supply to hepatocellular carcinoma, next to the hepatic artery. Conclusion: Knowledge of variations of inferior phrenic artery origin could be valuable during treatment of hepatic neoplasm, liver transplants, biliary tract surgery and during tanscatheter oily chemoembolisation technique.

An undocumented variation involving auriculotemporal nerve, inferior alveolar nerve and middle meningeal artery.

Auriculotemporal nerve typically has two roots, encircling the middle meningeal artery, one anterior to it and another posterior to it as well as maxillary artery. The middle meningeal artery is largest of the meningeal arteries, ascends between the sphenomandibular ligament and lateral pterygoid muscle and traverses between the roots of the auriculotemporal nerve before entering the cranial cavity through the foramen spinosum. The knowledge of the neurovascular relationships of the infratemporal region is significant in surgical practice. We present a case of unusual communication between the auriculotemporal nerve and inferior alveolar nerve together with an extraordinary change in relations with the middle meningeal artery. Some clinical implications that these relations may have on the development of the supplementary innervations and the surgical interventions in this region are discussed in this article.
