tubercle

(to͞o`bərkyo͞ol') [Lat.,=little swelling], small, usually solid, nodule or prominence. In anatomy the term is applied to natural prominences in certain muscles, to nerve nuclei of the central nervous system, and to eminences on bones, especially in regions where muscles (through tendons) or bones (through ligaments) are attached. In dentistry tubercle refers to the cusp of a tooth. In pathology it describes small morbid growths, particularly the lesions of tuberculosistuberculosis
(TB), contagious, wasting disease caused by any of several mycobacteria. The most common form of the disease is tuberculosis of the lungs (pulmonary consumption, or phthisis), but the intestines, bones and joints, the skin, and the genitourinary, lymphatic, and

designated the connecting line between pubic tubercle and medial femoral epicondyle as the longitudinal reference line, the connecting line from pubic tubercle to greater trochanter of femur as the horizontal reference line.
(2,16,17) These shear forces place stress on the inguinal wall musculature and can lead to attenuation of local soft tissues, including the following: tearing of the transversalis fascia or conjoined tendon, abnormalities at the insertion of the rectus abdominis muscle, avulsion of the internal oblique muscle fibers at the pubic tubercle, intrasubstance tear of the internal oblique muscle, and attenuation of the external oblique muscle and aponeurosis.
In order to describe the mediolateral relationship between NEPs and bony landmarks, another suture thread immersed in barium sulfate was sewn into the skin between the femoral greater trochanter and the pubic tubercle and designated as H (Fig.
2 cm medial to pubic tubercle, upper margin should be approximately 3 to 4 cm above the Hesselbach's triangle and 3 cm lateral to deep inguinal ring.
A swelling over left inguinal region 5 X 5 cm present % inch above and lateral to pubic tubercle, no warmth with mild tenderness, irreducible, no cough impulse with restricted mobility.
This emerged below and lateral to the pubic tubercle. The rest of the abdominal examination was unremarkable.
oblique aponeurosis (Total 35 mL) through wheal 2, 5 mL solution was injected directly on to the pubic tubercle, a further 5 mL lateral to the pubic tubercle at a depth of 3 cm and further 10 mL subcutaneously towards the umbilicus for a distance 8 cm (Total vol.
The longer end of the onlay patch covered the posterior wall and overlapped the pubic tubercle. The onlay patch was then secured with the clip or suture with pubic tubercle and mid portion of transverses aponeurosis using 3-0 Prolene.
The cord structures are then separated from the inferior flap of EOA by blunt dissection and elevated from the inguinal ring en masse with the fingers of one hand at the pubic tubercle so that the index finger can be passed underneath to meet the index finger of the other.
This was followed by the placement of appropriate sized polypropylene mesh in the posterior wall which was tied to the pubic tubercle, inguinal canal below, conjoint tendon above and around the spermatic cord at the deep inguinal ring using 2/0 polypropylene suture.
Using a proper sized polypropylene mesh, which extended 2cm medial to pubic tubercle, 3cm above the Hesselbach's triangle and 5cm lateral to the inguinal ring, LMH were done; 2-0 vicryl were used to fix the mesh in the conjoint above and rectus sheath medially.
