TO EVALUATE THE MORPHOLOGICAL AND MORPHOMETRIC FEATURES OF ADULT HUMAN CADAVERIC RIGHT LUNG IN NORTH INDIAN POPULATION

Objectives: In the present study, different morphological and morphometric features of adult human cadaveric right lungs were observed and noted on the predesigned pro forma. Not much of such measurements have been done in the past. The mean values and standard deviations are calculated. The data thus obtained were tabulated scrutinized, analyzed, and compared with the earlier studies wherever possible. If any variant from the normal is observed, an attempt has been made to explain the same on ontogenic or phylogenic basis. Methods: The present study has been conducted on 50 adult human cadaveric right lungs obtained from embalmed cadavers, used for dissection in the department of Anatomy, Govt. Medical College, Amritsar, formed the material for the current study. Results: Majority of the lungs (49 [98%]) were spongy in texture while 1 (2%) lung was firm to touch. It is evident that majority of lungs depicted mottling in the form of black, brown or grey in color in 38%, 28%, and 26% of the specimens, respectively. A complete grey, brown, or brownish black color was seen in 2% lungs each. In one lung yellow mottling was seen which could be because of fat deposition. Length of posterior border (19.9cm) was more as compared to anterior border (17.8 cm). Lungs were measured both along lateral and medial surfaces. Along the lateral surface its mean value was 18.52±3.178 cm (Range 12–25 cm) while along medial surface its mean value was 15.11±2.241 cm (Range 9–23 cm). The mean AP width of right lung at center was 11.05±2.864 cm (Range 7–23 cm) and along inferior border was 13.26±2.743 cm (Range 9–20 cm). The mean mediolateral width was found to be 7.536±2.318 cm with range being 4–15.2 cm. Conclusion: Knowledge of normal measurements of lungs and their variations may help cardiothoracic surgeons to avoid undue complications during surgery. Furthermore, it may help radiologist to resolve perplexed radiographic findings

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. Transcutaneous electric nerve stimulation (TENS) is an emerging and promising option for management of such patients. Aims and Design: The present study was designed with an aim to study the efficacy of TENS in management of trigeminal neuralgia. Materials and Methods: The study was conducted on 30 patients of trigeminal neuralgia confirmed by diagnostic nerve block. They were given bursts of TENS for 20-40 days over the path of the affected nerve and subsequently evaluated at 1 month and 3 month intervals by visual analogue scale (VAS), verbal pain scale (VPS), a functional outcome scales for main daily activities like sleep, chewing, talking, or washing face. Results: The results showed that, on VAS, the score decreased from 8.9 (Pre TENS) to 3.1 at 1 month and 1.3 at 3 months, and on VPS, the score decreased from 3.5 (Pre TENS) to 1.2 at 1 month and 0.3 at 3 months. Similarly, a considerable decrease in scores was seen on functional outcome scale for different activities. No side effects like irritation or redness of skin were seen in any of the patients. Conclusions: Thus, TENS was found to be a safe, easily acceptable, and non-invasive outdoor patient department procedure for management of trigeminal neuralgia

Symmetry and isometry of human adult hyoid bone: A cadaveric study in North Indian population

Introduction: Hyoid bone fracture is one of the most integral parts of internal examination during autopsy of hanging, ligature strangulation, or a throttling case. The reasons why some hyoids fracture and others do not may be related to the nature, magnitude, and position of the force applied to the neck, age of victim, nature of instrument (ligature or hand) used to strangle, and intrinsic anatomical features of the hyoid bone, such as rigidity and shape of the bone and symmetry of greater horns. Materials and Methods: The material for the present study comprised of 30 dried hyoid bones (M:F: 15:15). Their outline was drawn on the graph paper to study the symmetry and isometry of the bone. Results: Forty percent of the hyoids bones were symmetrical, while 60% were asymmetrical. Similarly, the number of anisometric bone is more (86.6%) as compared with isometric bone (13.3%) in both the sexes. Conclusion: Hyoid bone is not bilaterally symmetrical bone. The incidence of asymmetrical and anisometric bones is more as compared with symmetrical and isometric bones in both the sexes

A Cadaveric Study of Different Angles of Scapula and Their Role in its 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. The study was conducted on 100 scapulas (R:L = 50:50) obtained from Department of Anatomy, Government Medical College, Amritsar. For measuring the angles, centimetre scales and protractor were used. Results: The mean value of superior angle was observed to be 100.830 (R=100.320 : L=101.340) ; inferior angle was 63.620 (R=68.10 : L=59.140) ; lateral angle was 61.720 (R=65.90 : L=57.540) ; medial angle was 147.640 (R=151.320 : L=143.960) ; acromial angle was 106.470 (R=107.680 : L=105.260) and coracoid angle was 83.30 (R=84.240 : L=82.020). Conclusions: It was observed that all angles were higher in the right sided bones except superior angle. Also a wide range was seen in all the angles. _______________________________________________________________________________________ Keywords: acromial; coracoid; inferior; medial; superior. ______________________________________________________________________________________

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. Methods: The present study was carried out to determine the angle of tibial torsion in 100 adult dry tibia bones in the Department of Anatomy, Government Medical College, Amritsar. The study group comprised 50 males and 50 females with equal number of right- and left-sided bones. The measurements were meticulously recorded and the data were subjected to statistical analysis. The results were analyzed and discussed in the light of existing literature. Results: On the right side, it was found to be 29.84° ± 4.86°° (range = 22.00° -38.00°) in males and 28.92° ± 5.10°° (range = 15.00°-38.00°) in females. On the left side, it was found to be 28.00° ± 4.94°° (range = 20.00°-40.00°°) in males and 28.12° ± 4.28°° (range = 20.00°-37.00°°) in females. Conclusion: The present study is an endeavor to provide baseline data with reference to the angle of tibial torsion in the Indian population. The results of the study assume special importance in view of the technical advancements in reconstructive surgical procedures in orthopedic practice
