Angiography and different investigations are done by catheterization of the femoral artery. 50 femoral triangles in 25 human were dissected. The femoral artery and its major branches were dissected. The average distance of the superficial circumflex iliac artery origin from mid inguinal point on right side 12.6 mm and on left side 14.4 mm. with highest distance 45mm. Average distance of origin of the superficial epigastric artery on right side 23.08mm and on left side 22.28mm from the mid inguinal point. Average distance of origin of the superficial external pudendal artery on right side 26.4mm and on left side 26.5mm from the mid inguinal point. The profunda femoris artery originated from either posterior posterolateral or lateral aspect of the common femoral artery. The distance of origin of profunda femoris from the mid inguinal point on the right side and left side commonly placed between 40 and 60mm. Deep external pudendal artery arises at the distance of 30.02 mm on right side and 29.80 mm on left side .

  • The Arterial Supply of the Patellar Tendon: Anatomical Study with Clinical Implications for Knee Surgery
    Clinical Anatomy 22:371–376 (2009) ORIGINAL COMMUNICATION The Arterial Supply of the Patellar Tendon: Anatomical Study with Clinical Implications for Knee Surgery JACK PANG,* SARAH SHEN, WEI REN PAN, IAN R. JONES, WARREN M. ROZEN, AND G. IAN TAYLOR Jack Brockhoff Reconstructive Plastic Surgery Research Unit, Department of Anatomy and Cell Biology, University of Melbourne, Parkville, Victoria, Australia The middle-third of the patellar tendon (PT) is well-established as a potential graft for cruciate ligament reconstruction, but there is little anatomical basis for its use. Although studies on PT vascular anatomy have focused on the risk to tendon pedicles from surgical approaches and knee pathophysiology, the significance of its blood supply to grafting has not been adequately explored previously. This investigation explores both the intrinsic and extrinsic arterial anatomy of the PT, as relevant to the PT graft. Ten fresh cadaveric lower limbs underwent angiographic injection of the common femoral artery with radio- opaque lead oxide. Each tendon was carefully dissected, underwent plain radi- ography and subsequently schematically reconstructed. The PT demonstrated a well-developed and consistent vascularity from three main sources: antero- proximally, mainly by the inferior-lateral genicular artery; antero-distally via a choke-anastomotic arch between the anterior tibial recurrent and inferior medial genicular arteries; and posteriorly via the retro-patellar anastomotic arch in Hoffa’s fat pad. Two patterns of pedicles formed this arch: inferior-lateral and descending genicular arteries (Type-I); superior-lateral, in- ferior-lateral, and superior-medial genicular arteries (Type-II). Both types sup- plied the posterior PT, with the majority of vessels descending to its middle- third.

ISSN 2321- 4287 Original Research Article DOI: http://dx.doi.org/10.16965/ijar.2015.316 AN ANATOMICAL STUDY OF GRACILIS MUSCLE AND ITS VASCULAR PEDICLES M.S. Rajeshwari *¹, B.N. Roshan kumar ². *1 Professor, Department of Anatomy, Bangalore Medical College & Research Institute, Bangalore, Karnataka, India. 2 Professor and Head, Department of Orthopaedics, RajaRajeshwari Medical College Bangalore, Karnataka, India. ABSTRACT Background: Gracilis muscle being easily accessible and functionally a weak muscle is suitable for muscle graft to replace the damaged muscle in any part of the body. The length of the muscle, vascular pedicles and limited donor site morbidity helps the surgeon to plan accordingly. The muscle receives a number of vascular pedicles ranging from one to five. The source of these pedicles varies. Material and Methods: The study was conducted on 36 formalin fixed lower limbs of both sexes of unknown age from the department of Anatomy, BMCRI, Bangalore. Results and Discussion: In 75% of limbs two vascular pedicles were seen penetrating the muscle at different levels and in 25% accessory pedicles were seen in the lower 2/3rd of the muscle. Conclusion: The findings suggest that the first vascular pedicle to the muscle is always constant in position accompanied by its venae comitans and branch from obturator nerve and is placed at a distance of 10.5cms±2cms from the pubic tubercle. KEY WORDS: Gracilis Muscle, Vascular Pedicle, Muscle Transplantation, Flap Reconstruction. Address for Correspondence: Dr. M. S.

H.; JUNG, S. J.; LEE, H.; CHOI, I. J. & LEE, J. H. Topography of the middle genicular artery is associated with the superior and inferior genicular arteries. Int. J. Morphol., 35(3):913-918, 2017. SUMMARY: Total knee arthroplasty has increased substantially, however anatomical studies of the genicular arteries (GAs) in this region are rare. The aim of this study was to identify the pattern and branching points of GAs and their relationship. In 42 lower limbs, the pattern and branching points of GAs were confirmed. The horizontal line which extends between the most prominent point of the lateral and medial margins of patella was defined as a reference line. The distance of branching point of the GAs from the reference line was measured, and the correlations between these points were analyzed. The superior lateral and medial genicular arteries (SLGA and SMGA) were located at + 38.17 ± 3.10 mm and + 32.68 ± 3.83 mm from the reference line, respectively. The middle genicular artery (MGA) was originated from + 7.57 ± 3.98 mm. The inferior lateral and medial genicular arteries (ILGA and IMGA) were located at - 18.46 ± 2.63 mm and - 24.09 ± 3.52 mm, respectively. The branching points of the SLGA changed significantly according to the arterial branching pattern with the MGA.

Medical College, Jammu, India Email: [email protected] Abstract The femoral artery is the continuation of external iliac artery. It begins behind the inguinal ligament midway between anterior superior iliac spine and pubic symphysis, descends along the anteromedial part of the thigh in the femoral triangle, enter and passes through the adductor canal, and becomes the popliteal artery as it passes through an opening in adductor magnus near the junction of the middle and distal thirds of the thigh. Since femoral artery has vast clinical applications in almost all fields of medicine, it is crucial to know the arterial characteristics of lower extremity before proceeding with any interventional or surgical procedure. Due to the above said reasons, We have done a cadaveric study about femoral artery, its branching pattern and variations, with its clinical application. The origin of the femoral artery coincided with the mid inguinal point in most of the cases. The origin of the profunda femoris artery is lateral to the femoral artery in most of the cases .
