Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Background:

Elbow arthrograms are crucial for diagnosing intra-articular pathologies.
The radiocapitellar approach is commonly used but can present challenges.
Evaluating alternative approaches is essential for optimizing diagnostic procedures.

Purpose of the Study:

To assess the diagnostic accuracy and patient experience of the transtriceps approach for elbow arthrograms.
To compare the transtriceps approach with the traditional radiocapitellar method.
To determine the safety and efficacy of the transtriceps approach.

Main Methods:

Retrospective evaluation of two patients undergoing MRI arthrograms of the elbow via the transtriceps approach.
Procedures performed under fluoroscopic guidance with specific patient positioning and a 25-gauge needle.
Assessment of diagnostic quality, contrast leakage, and patient-reported pain (0-10 scale).

Main Results:

Successful contrast visualization within the elbow joint in both cases.
MRI confirmed no extra-articular contrast leakage or bubbles.
Patients reported zero pain during the procedure, indicating excellent comfort.

Conclusions:

The transtriceps approach is a diagnostically sound and effective method for elbow arthrograms.
This approach offers a significant advantage in patient experience, being virtually painless.
The transtriceps approach is a viable and potentially superior alternative to the radiocapitellar approach for elbow arthrograms.
