Summary
This study clarifies the rectus abdominis tendon (RAT) insertion anatomy for pelvic reconstruction. Surgeons can safely mobilize the RAT up to 33mm medially and 36.5mm laterally during anterior approaches.
Area of Science:
- Orthopaedic Surgery
- Anatomy
- Pelvic Reconstruction
Background:
- Anterior approaches in pelvic and acetabular surgery require clear understanding of rectus abdominis tendon (RAT) anatomy.
- Secure mobilization of the RAT from the pubic bone is crucial for surgical success.
Purpose of the Study:
- To determine the insertional anatomy of the rectus abdominis tendon (RAT).
- To clarify the safe mobilization extent of the RAT from the pubic bone during anterior pelvic reconstruction.
Main Methods:
- Dissection of 11 fresh-frozen cadaveric pelvises using the anterior intrapelvic approach (AIP).
- Identification, marking, and measurement of the RAT footprint on the pubic bone.
Main Results:
- Analysis of 19 RAT insertions.
- Average medial vertical length: 33 mm (range 26-42 mm).
- Average lateral vertical length: 36.5 mm (range 26-46 mm).
- Proximal insertion width: 20.42 mm (range 14-24 mm).
- Distal insertion width: 10.45 mm (range 8-13 mm).
Conclusions:
- The RAT can be safely mobilized up to 33 mm medially and 36.5 mm laterally.
- This anatomical data enhances surgeon understanding for safer surgical release in anterior pelvic approaches.

01:21Muscles of the Abdomen
1.0K
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and...

01:22Appendicitis-I: Introduction
86
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

01:26Muscles of the Pelvic Floor and Perineum

The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

01:19Abdominal Regions and Quadrants
7.3K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

01:16Bones of the Lower Limb: Femur and Patella
2.2K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

01:25Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...
