Abstract

Background:

Avulsion injuries of the pelvis and hip region are typical injuries in adolescent athletes but can be found in adults as well. Typical sites for avulsion injuries include the origin/insertion of tendons and ligaments. Among adolescents, the not yet ossified apophysis is also frequently involved. The pelvis and hip are especially prone to such injuries due to their complex musculotendinous anatomy. Clinical history and physical examination in combination with the recognition of typical imaging findings are essential for correct diagnosis of these mostly acute, but sometimes also chronic injuries.

Methods:

This review article describes typical avulsion injuries of the pelvis and hip and illustrates common radiological findings. Taking current literature into account, there is a special focus on the trauma mechanism, clinical examination, typical imaging findings and clinical management.

Results And Conclusion:

Detailed knowledge of musculotendinous anatomy and typical injury mechanisms allows a correct diagnosis of avulsion injuries often only based on clinical examination and radiographic findings. Further imaging with ultrasound and MRI may be necessary to evaluate tendon retraction in non-osseous avulsion injuries and extent of soft-tissue damage. Knowledge of potential complications of acute/chronic injuries can help to avoid unnecessary examinations or invasive interventions. Conservative management of avulsion injuries usually leads to functionally good results. However, in the case of competitive athletes, relatively wide bone fragment dislocation or marked tendon retraction, operative re-fixation may be considered in order to expedite the rehabilitation process.

Key Points:

· Avulsion injuries are common injuries at the pelvic region especially in adolescent athletes, due to not yet ossified apophysis.. · Excellent anatomical knowledge is essential for proper diagnostic evaluation and predicting the mechanism of injury.. · Imaging plays a crucial role in diagnosing avulsion injuries starting from X-Ray and using MRI and CT for anatomical details by utilizing multiplanar capabilities..

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

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...

Muscles that Move the Thigh

Muscles that Move the Thigh

The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

Abdominal Regions and Quadrants

Abdominal Regions and Quadrants

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...

Arteries of Lower Limbs

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Abdominal Aorta

Abdominal 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...

Muscles of the Pelvic Floor and Perineum

Muscles 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...
