Posterior Leaflet of Mitral Valve-Is it Really Tri-scalloped? -A Morphological and Morphometric Study in North Indian Cadaveric Hearts.

Background: Maintaining normal left ventricular geometry and function depends on the mitral valve's normal integrity. Irreparable damage to the mitral valve calls for its replacement using either a valve made up of biological tissue or metal, pyrolytic carbon, and similar materials.

Materials And Methods: The material consists of 50 formalin-fixed adults, seemingly normal cadaveric hearts of either sex which were received from the Department of Anatomy of various institutes in the north region.

Intratemporal Facial Nerve Anatomy and its Variations in 30 Cases of Cadaveric Temporal Bones.

It is important for the ENT surgeon to be familiar with the anatomy of the facial nerve and to prevent iatrogenic injury to nerve as it shows variations in its intratemporal course. Present study was done to delineate the intratemporal course of facial nerve and observe its variations. Thirty wet cadaveric temporal bones were dissected in the temporal bone dissection laboratory in the Department of Otorhinolaryngology and Head Neck Surgery, Government Medical College, Patiala.

Morphometric Analysis of the Corpus Callosum Using Cadaveric Brain: An Anatomical Study.

Purpose: The present study was conducted to measure the longitudinal and vertical lengths of the brain hemisphere, longitudinal length of the corpus callosum (CC), and distances of CC from the frontal and occipital poles, in order to define its topographic location within the brain hemispheres.

Materials And Methods: Fifty formalin-fixed human brains were dissected in the midsagittal plane. The parameters measured were as follows: (i) straight distance between frontal and occipital pole (AB); (ii) vertical distance (height) between the upper and lower surface of the brain hemisphere (CD); (iii) frontal pole to anterior-most point of CC (EG); (iv) occipital pole to posterior-most point of CC (ZO); (v) anterior-most point to posterior-most point of CC (EZ); and (v) anterior edge of genu to the upper end of lamina terminalis (EF).

Re-definition of position and calculation of safe area for axillary nerve in deltoid muscle with its clinical relevance: a cadaveric study.

Several authors have made efforts to define the position of the axillary nerve within deltoid muscle and to calculate the so called safe area for this nerve but it still remains a matter of debate. The primary aim of the study was to investigate the acromio-axillary (AA) distance and its correlation with upper arm length. The secondary aim was to re-define the safe area for axillary nerve within deltoid muscle.

Morphological and Morphometric Study of Coronary Sinus in North Indian Population.

Introduction: Coronary sinus (CS) is the largest vein draining the blood from heart. It is a muscular tube of about 2 cm to 3 cm length and 1 cm in caliber. It has become a clinically important structure through its role in providing access for different cardiac procedures viz.

Cadaveric Study of Berretini Communications in North Indian Population.

Introduction: Intercommunication between peripheral nerves deserves special attention in view of their clinical significance. Superficial palmar communication between the median nerve and ulnar nerve is referred to as Berrettini Anastomosis. The presence or absence of this communicating branch varies between individuals.

Martin-Gruber Anastomosis- A Cadaveric Study in North Indian Population.

Introduction: Communications between peripheral nerves are important in the light of the fact that these are responsible for a myriad of clinical symptoms. Communication between the median nerve and ulnar nerve (Martin-Gruber anastomosis) is a frequent finding observed anatomically in 10%-30.6% subjects and physiologically in 5-40%.

Morphometric analysis of upper end of tibia.

Introduction: The present study aims to assess different morphometric parameters of condylar and intercondylar surface of tibia and to compile the results, analyze and formulate a baseline data for future studies with relevance to Indian population and also to compare the current data with accessible literature for pertinent surgical utilities. Morphometric parameters of upper end of tibia can be used to guide treatment and monitor outcome of total knee replacement surgeries. Information regarding morphometry of upper end of the tibia is vital as it provides reliable method of assessing knee deformity.

A cadaveric study of different angles of scapula and their role in kinesiometrics and muscle morphology.

Introduction: The bipedal gait and consequential freedom of the upper limb in human beings has made the movements of the shoulder joint a subject of extensive investigations. The scapular angles provide the base and leverage to various muscles and have been correlated with the different movements of the shoulder joint.

Methods: In the present study, different angles of scapula namely superior, inferior, lateral, medial, acromial and coracoid angles were measured in the North Indian population.

Human tibial torsion--morphometric assessment and clinical relevance.

Background: Tibial torsion is an important anatomical parameter in clinical practice and displays variability among individuals. These variations are extremely significant in view of alignment guides such as those related to rotational landmarks of tibia in total knee arthroplasty. Further, precise knowledge and information pertaining to angle of tibial torsion also helps in correction of traumatic malunion or congenital maltorsion of tibia.

A two trunked brachial plexus: a case report.

The brachial plexus is a major and a complicated plexus at the root of the neck. It is formed by the ventral primary rami of the C5, C6, C7, C8 and the T1 spinal nerves. During the routine under graduate dissection of the right upper limb of an adult female cadaver, a variant pattern of a two trunked brachial plexus was encountered.

Multiple musculovascular anomalies in the superior extremities of a cadaver: a case report.

During the evolution from the lower animals to man, the upper limbs have acquired a great mobility, but at the cost of their stability. The reverse is true for the lower limbs. The muscular anomalies which are common in the upper limbs are largely explainable on a phylogenetic basis.

Prevalence of the persistant median artery.

Introduction: Neurovascular variations in the upper limb are common and they are well documented. An accurate knowledge of the normal and the variant anatomy of the median nerve and the median artery are important for clinical procedures and for vascular surgeries. The persistant median artery is one such anomaly which was seen in 6.

The role of the anterior border of the hip bone in sexual dimorphism: a morphometric study in the North Indian population.

Understanding sexual dimorphism is very important in studies of human evolution and skeletal biology. The ability to determine sex from unknown skeletal remains is vital and methods to do this on the various bones of the human skeleton have been researched extensively especially in the studies related to forensic anthropology. The distinctive morphology and clear sexual dimorphism of the hip bone makes it an ideal bone for sex determination.

Role of transcutaneous electric nerve stimulation in the management of trigeminal neuralgia.

Background: Trigeminal neuralgia typically involves nerves supplying teeth, jaws and face of older females. Though the etiology is usually obscure, different treatment modalities have been tried for it viz. medicinal treatment, injection alcohol, peripheral neurectomy, rhizotomy, and microvascular decompression etc.
