The Katikataruna marma, has helped in giving relief in many diseases related to the prstha pradesha & the adho udara bhaga related pathologies.
The details of the Katikataruna, as per the classical textual reference of Sushrutha & it’s interpretation as of my understanding with the modern anatomy is being discussed henceforth.
On either side of the vertebral column at the place where in each of the component (i.e the Ileum & Ischium) of the shroni kandam (hip bone) join together to form the Katikataruna marma.
Dalhan commenatary on Katikataruna:
The word Prati shroni kAndam is referred to as PratishronikarNou by some scholars. This ShronikarNou is present on either sides above the Trika (Sacrum) bone attached to the pelvis. The structure that which resembles the ear in the pelvis is supposed to be auricular surfaces of the both the Ileium & Sacrum bone together forming the sacro-iliac joint. This joint is has a peculiarity in the way the cartilages are attached to the articular surfaces of either of the Ilium & Sacrum bones, which can be understood from the following statement of Gray's anatomy, which reads as "The sacroiliac articulation is an amphiarthrodial joint, formed between the auricular surfaces of the sacrum and the ilium. The articular surface of each bone is covered with a thin plate of cartilage, thicker on the sacrum than on the ilium. These cartilaginous plates are in close contact with each other, and to a certain extent are united together by irregular patches of softer fibro cartilage, and at their upper and posterior part by fine interosseous fibers."
Hence, the taruna predominance in this particualr joint present at the Katika regions, helps in determining the sacroiliac joint to be considered as the katika taruna..
My above observation may differ from the work of my seniors in the field of Marmas, but I am strongly akin of the above opinion.
The Katikataruna are two in numbers, one on either side of the back.
Katikataruna:- Type of Marma classification:-
The katikataruna is a kalantara pranahara marma.
And further classified under the category of Asthi predominant marma (Vide:- reference of Dalhan above).
Katikataruna viddha lakshana:-
This marma on getting injured results in internal blood loss causing pallor and gradually leads to death
Anatomical Structures in close association with the katikataruna are :-

Blood vessels:- External iliac artery & vein;Hypogastric artery
Morbidity of diseases involving Katikataruna:-
The following diseases shows some kind of hectic activity involving the Katikataruna marma, where in the tenderness observed in the marma is more than the usual nature.
