Introduction: Muscular variations in the form of accessory muscles are common and observed during cadaveric dissections, surgeries or investigative radiological procedures. Knowledge of such variations in upper limb is useful for hand surgeons and neurosurgeons. Materials and Methods: Total 156 (80 of right side and 76 of left side) upper limbs of unknown sex were dissected for presence of accessory muscles in the flexor compartment of the forearm. Observed accessory bellies and anatomical variant muscles were studied for its origin and insertion, size and shape and its important relations. Observations: Accessory head for the flexor pollicis longus (ahFPL) was the most common variation found in 56 (36%) limbs. Accessory head for the flexor digitorum profundus (ahFDP) was observed in five (3.2%) limbs, and accessory head for the flexor digitorum superficialis (ahFDS) in two limbs (1.2%,). Two accessory bellies in the same hand with common or separate origin were found in 5 limbs (3.2%). An anatomical variant flexor carpi radialis brevis (FCRB), which is not very common, was found in one limb. Conclusion: Accessory bellies of the muscles in the forearm are known for compression neuropathies like anterior interosseous nerve syndrome (AINS). Available accessory muscles like FCRB could be used for tendon transfers in patients with arthritis of thumb. Awareness of such variations helps in diagnosis of neuropathies, to avoid complications during surgeries and most importantly accessory muscles could be used for tendon graft/ transfer to to transform disability into functional hands.
Background: Rouviere’s sulcus (RS) was first identified in 1924 by Henri Rouviere. It lies oblique to the anterior and inferior border of the liver and holds the right portal pedicle. Material and Methods: The study was conducted in the Department of Anatomy of a Medical College in Maharashtra, India, on 45 cadaveric livers. The morphological observations made were: presence/ absence RS; direction of RS (oblique/ horizontal/ vertical); sulcus type ( deep/ slit/ scar); length, width and depth; presence of right hepatic pedicle; distance of the hepatic vessels from edge of the sulcus . Results: 40 livers showed the presence of Rouviere’s Sulcus. It was absent in five specimens. Direction was horizontal in 40%, oblique in 57.5% and vertical in 2.5% .26 livers showed a deep type of sulcus, 12 showed the slit type and 2 showed scar type .29 livers showed the right hepatic pedicle entering the RS. Average length, depth, of the RS was 2.35 cm and1.07 cm respectively. The average width was 0.32cm at medial end, 0.22cm at midpoint and 0.1cm at lateral end. Present study has added the details of depth of vessels from the edge of RS, which was not recorded in earlier studies. Depth of vessels from the edge of the sulcus was average 5mm (0.5cm) for the right branch of the hepatic artery and was 12mm (1.2cm) for the right branch of portal vein. Conclusion: Rouviere’s sulcus is a reference landmark for surgeons during laparoscopic surgeries on gall bladder and during hepatic resection to avoid injuries. This study wishes to provide detailed morphological data of the Rouviere’s Sulcus to hepatobiliary surgeons including depth of hepatic vessels in the RS as an added parameter to aid them in their surgical endeavor. KEY WORDS: Rouviere’s sulcus, Anatomical Landmark, Morphology, Depth, Hepatobiliary Surgery.
Background: Anatomy of the hip must be taken into account to study the anatomy of various surgical approaches. Reconstruction of the acetabulum in patients with significant acetabular bone deficiency remains a major challenge in revision total hip arthroplasty. Appropriate anatomic concepts for surgery to treat femoroacetabular impingement require a precise appreciation of the native acetabular anatomy. Since the acetabulum is not always of same shape, width or depth, joint congruences are frequent with minor anatomical variations in the shape of the acetabulum. Hence the present study was undertaken as controversies still exist on the importance of these variations and to prevent problems following surgical procedures such as acetabular reconstruction and femoroacetabular impingement.Methods: Material of the study consisted of 110 human hip bones (60 males and 50 females). Depth of Acetabulum (DA) was measured on these hip bones on both the sides. Statistical analysis was done using SPSS (Statistical Package for the Social Sciences) version 11 and Microsoft Excel 2007.Results: The mean depth of acetabulum in male was 26.89 mm and female was 25.31 mm. The mean depth of acetabulum on right side was 26.24 mm and left side was 26.11 mm. Depth of the acetabulum was greater in males as compared to females and the differences were statistically significant. Depth was greater on the right side as compared to the left side but the difference was statistically non-significant.Conclusions: Depth of the acetabulum was greater in males as compared to females.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
