Learning objectives

The iliopsoas muscle is one of the main flexor muscles of the hip and plays a very important role in the static of the spine. In this poster we will study the following issues: - We will describe the anatomy and function of the iliopsoas tendon. - Review the different imaging methods of the tendon. - Describe the tendon pathology

Background

ANATOMY: The iliopsoas muscle is found in the abdominal cavity and in the anterior part of the thigh. It is one of the most powerful muscles of the body, the main flexor of the thigh and the most powerful of the flexor muscles of the hip. It is constituted by two parts: a long medial part, the psoas, and a wide lateral part, the iliac. The psoas or psoas major portion originates in the T12 vertebrae and the first five lumbar vertebrae (T12-L5), as well...

Imaging findings OR Procedure Details

The iliopsoas tendon can be evaluated with ultrasound or magnetic resonance. The major advantages of ultrasound include dynamic evaluation of structures, low cost and wide availability while MR imaging provides higher soft tissue resolution and is particularly useful for showing other structures like bones and joints. US EVALUATION: To examine this tendons with ultrasound, one trick is first look for the rectus femoris in the axial plane, which is very easy to identify due to its characteristic central septum, and continue it proximally until its...

Conclusion

Hip pain is a clinical picture that can be caused by multiple pathologies, including iliopsoas tendon injuries. Iliopsoas muscle tendon unit presents a very complex anatomy and its knowledge will help us explain its functions and to understand possible injuries that may occur. Its treatment is usually conservative and a prompt diagnosis will permit a rapid recovery.
