The linea terminalis is the pronounced line separating the greater and lesser pelves, formed by the sacral promontory, the arcuate line, the pectineal line, and the pubic crest. The iliopectineal line is that part of the linea terminalis formed by the arcuate line and the pectineal line.

Sometimes, the pelvis cavity is considered to extend above the pelvic inlet, and in this case the pelvic inlet is used to divide the pelvic cavity into a false (above the inlet) and a true pelvis (below the inlet)….

Linea terminalis – Linea terminalis The terminal line of pelvis is a circular line the passes along the promontory of the sacrum dorsally, the wings of the ilia laterally and ends in the pecten of the pubis ventrally. It is circular in female animals an egg-shaped in male animal with the apex facing ventrally.

A hip fracture occurs when the upper part of the femur is broken. The hip is a ball-and-socket joint: the rounded top of the femur, called the femoral head, fits snugly into a cup-shaped area of the pelvis, called the acetabulum.

b) 61% of the patients with pelvic ring fractures were older than 65 years. c) The most common fracture type was Type B (58%), followed by Type A fractures (25%) and Type C fractures (17%). So, 75% of the pelvic ring fractures were classified as unstable fractures.

Medial to the pubic tubercle is the pubic crest, which extends from this process to the medial end of the pubic bone. It gives attachment to the conjoint tendon, the rectus abdominis, the abdominal external oblique muscle, and the pyramidalis muscle….

The primary benefit of pubic hair is its ability to reduce friction during sexual intercourse. Pubic hair can also help stop bacteria and other microorganisms from entering the body. Specifically, it can help trap dirt and pathogens that may enter the body through the vagina or penis.

(Left) An oblique fracture has an angled line across the shaft. (Right) A comminuted fracture is broken into three or more pieces. Femoral shaft fractures in young people are frequently due to some type of high-energy collision. The most common cause of femoral shaft fracture is a motor vehicle or motorcycle crash.

The linea aspera (rough line on the posterior shaft of the femur) reinforces the strength and is an attachment for the gluteus maximus, adductor magnus, adductor brevis, vastus lateralis, vastus medialis, vastus intermedius, and short head of the biceps.

The medial supracondylar line ends at the adductor tubercle, where the adductor magnus attaches. Fig 3 – Posterior surface of the right femoral shaft. Fractures of the femoral shaft are typically a high energy injury but can occur in the elderly as a result of a low energy fall.

Intertrochanteric line – a ridge of bone that runs in an inferomedial direction on the anterior surface of the femur, spanning between the two trochanters. After it passes the lesser trochanter on the posterior surface, it is known as the pectineal line.
