The paired medial crura conform the central-leg of the tripod, which is attached to the anterior nasal spine and septum, in the midline. The lateral crura compose the second-leg and the third-leg of the tripod, and are attached to the (pear-shaped) pyriform aperture, the nasal-cavity opening at the front of the skull.
Front and posterior views. Saphenous, ... The medial crural cutaneous branches of saphenous nerve provide cutaneous innervation to the medial leg.
The medial crura are attached to the septal cartilage, forming fleshy parts at the front of the nostrils on each side of the septum, called the medial crural footpods. The medial crura meet at the midline below the end of the septum to form the columella [11] and lobule. The lobule contains the tip of the nose and its base contains the nostrils ...
The direction of insertion follows from lateral anterior distal to medial posterior proximal, aligning with the sinus tarsi. To prevent the guidewire from sliding back during trials, the guide pin is pushed towards the medial side and clamped with a hemostat. The guiding pin passes beneath the medial malleolus and above the posterior tibial ...
The horizontal mattress stitch is a suture technique used to close wounds.It everts skin well and spreads tension along the wound edge. [1] [2] [3] This makes it ideal for holding together fragile skin [4] as well as skin under high tension such as the distant edges of a large laceration or as the initial holding suture in complicated repairs.
The fibers of the crura diverge as they ascend, the most lateral being directed upward and lateralward to the central tendon. The medial fibers of the right crus ascend on the left side of the esophageal hiatus , and occasionally a fasciculus of the left crus crosses the aorta and runs obliquely through the fibers of the right crus toward the ...
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and size as well as thread material ...
Suturing continues 180 degrees from each initial suture. The position of the lateral sutures is reversed to expose the opposite side and sutured the same way. Glue can be used in the place of some sutures to limit scarring, resulting in better axonal growth, and speed up the surgery.
