Squatting Facets and Trochlear Extensions of Talus Bone in Indian Population

Introduction:The talus is a tarsal bone articulated with the tibia, fibula, navicular, and calcaneus bones to form supratalar, pretalar, and subtalar joints, respectively. A squatting facet is a kind of anomaly that forms on the surfaces where the tibia and talus articulate. The squatting facet states the daily activities and living style of society. Squatting is described as the hyperflexion of the hip and the knee and the movement of hyperdorsiflexion between the leg and the ankle. Materials and Methods: In the present cross‑sectional study, 600 dry adult human tali were taken from the osteology laboratory in the Department of Anatomy, King George’s Medical University, UP, Lucknow. Each talus was examined for the presence of various patterns of articular facets on the neck of the talus and extensions of its trochlear surface. Ethical clearance was obtained from the Institutional Ethics Committee, King George’s Medical University, Lucknow, as reference code: 121 ECMIIA/P3. Results: In our study, we observed that the lateral, medial, and combined squatting faces are 282 (47.64%), 49 (8.28%), and 22 (3.72%), respectively. Lateral, medial, and continuous trochlear extensions are 126 (21.12%), 120 (20.58%), and 31 (5.36%), respectively, in the Indian population. Conclusion: Modifications of the neck of the talus (squatting facets and trochlear extensions) are the result of prolonged squatting positions, which is a common habit of the Indian population, and incidences of these variations can be used as an anthropological marker for racial and regional differentiation of unidentified bones.

The Morphologicalanalysis Of Pterion In North Indian Population

Pterion is defined as an H-shaped small circular area formed by the junction of four bones: Frontal, Parietal, Temporal and Sphenoid on Norma lateralis of the skull. A 35 dry adult human skulls of unknown sex without any gross pathology or abnormalitywere taken for the study. Sphenoparietal was the commonest type of pterion observed on both the sides. Second most common type of pterion found in our study was stellate type. Stellate type of pterion was present only on right side of skull. The accomplishments of this study contribute to anatomical variations of the pterion, which are of interest to anthropologists, forensic pathologists and surgeons. This topic of study deserves further investigation in other populations from different geographical areas.

Variation In Branch Free Length Of Renal Artery And Its Clinical Significans: A 64-slice Ct Angiographic Morphometric Study

Background: Length of renal artery is an important morphological parameter while performing surgeries in renalarea. The present study was conducted to evaluate variations in length of renal artery.Materials and Methods: The study was conducted in the department of anatomy and department of radiology ofKing George’s Medical University, Lucknow. 53 subjects (106 renal arteries), undergoing 64-slice CT angiographyfor different indications were included in the study group. The angiographic images of all the subjects in abdominalregion were analyzed for renal arteries and their length was measured utilizing computerized tools.Results: The length of main renal artery varied from 8.5mm to 54.8mm on the right side. On the left side minimumlength was 7.7mm and maximum length was 48.8mm. The average length of renal artery was 30.5±10.4 mm on theright side and 26.91±10.0 mm on the left side. There was great variation in the length of renal artery due tovariation in site of ramification.Conclusion: The variation of renal artery length is critically important for maintaining vascularity of kidney aftersurgery

Coracoclavicular and costoclavicular joints at a common juncture: a rare phenomenon / Articulaciones coracoclavicular y costoclavicular en una unión común: un raro fenómeno

Movements at the human shoulder girdle are the result of complex interplay of glenohumeral, acromioclavicular, sternoclavicular and scapulothoracic articulations. Clavicle apart from articulating with the scapula and sternum is also connected with first rib by costoclavicular ligament and with coracoid process by coracoclavicular ligament. At times the area of attachment of these ligaments on clavicle, first rib and scapula show faceted apophysis suggesting the presence of additional diarthrodial articulations. Costoclavicular joint exists between clavicle and first rib and coracoclavicular joint between clavicle and coracoids process. Both these joints are described in the literature, but the concurrent occurrence of them in the same bone has not been reported yet. We found two clavicles, one of right and other of left side, both of them showed faceted apophysis for costoclavicular and coracoclavicular joint simultaneously, which is rare phenomenon.

Los movimientos de la cintura escapular humana son el resultado de la interacción compleja de las articulaciones glenohumeral, acromioclavicular, esternoclavicular y escapulotorácica. La clavícula, aparte de la articulación con la escápula y el esternón también está conectada con la primera costilla por el ligamento costoclavicular y con el proceso coracoides por el ligamento coracoclavicular. A veces la zona de unión de estos ligamentos de la clavícula, la primera costilla y la escápula muestran procesos facetarios que sugieren la presencia de nuevas articulaciones diartrodiales. La articulación costoclavicular existe entre la primera costilla y la clavícula y la articulación coracoclavicular entre la clavícula y proceso coracoides. Ambas articulaciones están descritas en la literatura, pero la aparición simultánea de ellas en el mismo hueso no se ha informado aún. Se encontraron dos clavículas, uno del lado derecho y otra del lado izquierdo, las dos presentaron procesos facetarios para las articulaciones costoclavicular y coracoclavicular simultáneamente, lo cual es un fenómeno raro.

Unusual lateral presentation of popliteal cyst: a case report.

The commonest cyst to occur in the popliteal region is the popliteal cyst and over the past years it has received much clinical attention. The commonest position of the popliteal cyst is in the posterosuperior aspect of the medial femoral condyle. The present case report describes a rare case of popliteal cyst, which was found on the postero-superior aspect of the lateral condyle of the femur. Interestingly, there are fewer reports of popliteal cysts occurring in the postero-superior aspect of the lateral condyle. We as anatomists describe the topographical anatomy of an unusual presentation of popliteal cyst in the postero-superior aspect of the lateral popliteal region and discuss its clinical significance. Anatomical knowledge of such anomalies may be important for clinicians, orthopedic surgeons and academicians in routine clinical practice.
