magnetic resonance imaging morphometry of the patella bone in South Indian population.

Racial differences exist in the dimensions of structures and the commercially available prostheses are designed based on the Caucasians. In this context, the goal of the present investigation was to determine the gender wise measurements of patella bone in South Indians. The present study included axial magnetic resonance images of the knee joint from 140 South Indian adults (70 males, 70 females; aged between 20-70 years).

Morphology and topography of the parietal emissary foramina in South Indians: an anatomical study.

The objectives of the present study were to study the prevalence of the parietal emissary vein in adult South Indian population and to study the distance of foramen from the sagittal suture. There were 58 adult human skulls in the present study which were available at the anatomy department of our institution. The study included 116 parietal bones which have been observed macroscopically for the number, prevalence and topography of the emissary foramen.

The Paracondylar Skull Base: Anatomical Variants and Their Clinical Implications.

Aim: The knowledge of the vasculature around the paracondylar region is important in neurosurgical procedures such as the paracondylar and lateral supracondylar approaches. The objectives of the present study were to determine the prevalence of paracondylar emissary foramina in the adult skull bases and to study the morphology of condylar canals and hypoglossal canals.

Material And Methods: The present study included 48 adult human skulls that were obtained from the gross anatomy laboratory of our institution.

A morphometric study of foramen ovale.

Aim: To note the morphological variations and morphometric details of foramina ovale in dry adult skulls of Indian origin.

Material And Methods: 82 dry adult human skulls of unknown sex and of Indian origin were obtained and variations in appearance and number of foramen ovale were noted. The length and width of the foramina ovale of both sides were determined using digital Vernier calipers and area (A) was also calculated and analyzed.

Morphological and topographical anatomy of nutrient foramina in the lower limb long bones and its clinical importance.

Background: Knowledge regarding nutrient foramina of bones is useful in surgical procedures such as microvascular bone transfer in order to preserve the circulation. The objective of the present study was to study the morphology and topography of nutrient foramina and to determine the foraminal index of the lower limb long bones to provide detailed data on such features.

Method: The study comprised examination of 206 lower limb long bones which included femora, tibiae and fibulae.

Anatomy of plantaris muscle: a study in adult Indians.

Aim: The plantaris muscle (PM) and its tendon is subject to considerable variation in both the points of origin and of insertion. The present study was carried out to fi nd the different types of origin, insertion and possible variations of the PM in the population of southern costal region of India.

Materials And Methods: 52 embalmed (Formalin fixed) cadaver lower limbs of 26 males (age ranged 48-79 years, mean age 68 years) were dissected, to study the origin and insertion of PM.

Variation and clinical significance of extensor pollicis brevis: a study in South Indian cadavers.

Background: de Quervain's disease is a condition in which there is pain in the radial styloid process caused by stenosing tenosynovitis of the abductor pollicis longus (APL) or/and extensor pollicis brevis (EPB) tendons in the first extensor compartment of the wrist. In this study we studied variations in the tendons of the EPB in the first extensor compartment and its site of insertion.

Methods: One hundred fifty six upper limbs from adult cadavers of south Indian origin were dissected to observe the number of EPB tendons and the presence of an osseo-fibrous septum in the first extensor compartment of the wrist.

Origin of the sinoatrial and atrioventricular nodal arteries in South Indians: an angiographic study.

Background: To study the arterial supply of the conducting system and its correlation with the dominance of the coronary arteries in the South Indian population.

Objective: To determine angiographically the origins of the sinoatrial nodal artery (SAna) and atrioventricular nodal artery (AVna) in Indians.

Methods: The study included 300 consecutive patients (114 females, 186 males; mean age, 55 years) living in the southern coastal region of India, who underwent coronary angiography either for the symptoms of chest pain, angina pectoris or positive Treadmill Test.
