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

. In botany it applies to the nodules on the roots or leaves of plants. In entomology the term is used for a compound or supplementary eye and for the nodules on the bodies of certain insects.

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.
If the tissues of the patient are weak and unsuitable for posterior wall repair, the inferior epigastric vessels are divided, the pre and retroperitoneal spaces from the pubic tubercle to the inguinal ligament are dissected and then a large synthetic mesh is placed into these spaces so that the entire peritoneal reflection in the inguinal canal is wrapped.
The mesh was then sutured along its lower edge to pubic tubercle, lacunar ligament and to the inguinal ligament beyond the internal ring with a continuous suture of 3-0 Prolene.
The upper leaf of the EOA is then sutured with the inguinal ligament from the pubic tubercle to the deep inguinal ring using Vicryl 1-0/Prolene 1-0 continuous sutures [Fig.
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.
Then master stitch was taken from pubic tubercle to the conjoint tendon with 0/1-1 silk sutures.
The first stitch was taken from the pubic tubercle and a darn was made locking each stitch between tendinous conjoint tendon and inguinal ligament, without tension in an interwoven fashion.
The lowness of pubic tubercle is associated with narrow origin of internal oblique muscle from lateral inguinal ligament.
of knots by fixing the prolene mesh by continous sutures and only knot was applied at pubic tubercle and this leads to reduced pain.
On Examination there was about 25 to 30 cm gut mucosal prolapse through an excoriated wound present in right groin below and lateral to pubic tubercle.
anterior-posterior distance between the pubic tubercles and posterior superior iliac spines [PSISs]), and distance between the anterior superior iliac spine (ASIS) (Figure 1) [11-13].
