Pubis is an angulated bone. It comprises a body, superior, and inferior ramus. Superior ramus helps in the formation of acetabulum. The thickening on the superior border of the body is the pubic crest and the most lateral prominent swelling of the pubic crest is named pubic tubercle (PT).

PTs are insertion points for inguinal ligament which extends from the anterior superior iliac spine (ASIS). Furthermore, the anterior pelvic plane which is a practical reference plane for pelvic orientation in space is constituted by a tangent passing between two ASIS and PTs.[1] In an ideal body posture, this plane is expected to be perpendicular to the ground. This is also the anatomical position of the hip bone. In the clinical setting, PT is used as a landmark for planning of inguinal lymphadenectomy, open inguinal hernia repair, obturator nerve block, and elevation of superficial circumflex iliac artery perforator flaps.[2],[3]

Faulty posture and associated multiple musculoskeletal diseases have been related to nonideal pelvis position.[4] Asymmetry within the pelvic structures is believed to lead to a cascade of postural compensations predisposing the individual to numerous neuromusculoskeletal dysfunctions.[5] Displacement of the anterior pelvic plane in a horizontal axis is defined as pelvic tilt. In a normal, asymptomatic population, anterior pelvic tilt was found among 85% of male and 75% of female participants, the tilt degree was in the range of 6°–7° for both sexes.[6] If a patient has a pelvic tilt, the anterior pelvic plane cannot be aligned parallel to the table on which the patient is lying.

In 2016, it was estimated for the global adult population, 39% of males and 40% of females were to be overweight.[7] We have been observing a similar increase in body mass index (BMI) among our inpatients.

This tendency of increased BMI hinders the location of the bony prominences. In an operation scenario where the patient is positioned supine, if the patient has an asymptomatic anterior pelvic tilt and has increased BMI, the superficial fascial system and the subcutaneous fat within the periphery of the pelvis will be displaced in an anterior-inferior direction. Moreover, if PT will be used as a landmark in this patient, a finger palpation directed from inferior to superior to locate PT will probably be misleading, as there will be excessive subcutaneous fat between palpating finger and bony prominences due to the positional displacement [Figure 1]. To avoid this pitfall, we suggest, the palpation to be made along the superior border of pubis and directed laterally. The edge point of the superior margin will correlate with PT [Figure 2].

We argue that this is a reliable method to locate PT as the anterior pelvic tilt will most probably go unnoticed during preoperative patient examination.
