Morphologic and Morphometric Evaluation of Oblique Popliteal Ligament - A Clinico-Anatomical Study.

The oblique popliteal ligament (OPL), chief posterior support of the knee, is an extension of the semimembranosus (SM) tendon and runs superolaterally to the lateral femoral condyle. Due to variations and immense functional value of the OPL, the present study was undertaken to explore the OPL morphology and morphometry. Thirty cadaveric lower limbs were dissected to observe the OPL in the floor of the popliteal fossa, and its general shape, number of bands and extensions were noted.

Variations in the Pattern of the Deep Palmar Arch of the Hand and Its Surgical Importance.

Background The deep palmar arch is formed by anastomosis of the continuation of the radial artery with the deep palmar branch of the ulnar artery. With recent advances in microsurgical techniques for vascular repair, the knowledge of variations in the arteries of the hand, as well as the caliber of these arteries, has become more important for surgeons. Additionally, radial artery harvesting for myocardial revascularization is being performed nowadays, for which collateral circulation in the hand through the palmar arches is a prerequisite.
