What is the supracondylar process of the humerus?

A bony projection on the anteromedial aspect of the distal humerus, approximately 5cm proximal to the medial epicondyle.

What are the common synonyms for the supracondylar process?

Supracondylar spur, supracondylar process, supratrochlear spur, or avian spur.

What complications can arise from the supracondylar process?

Neural impingement (median nerve), vascular impingement (brachial artery), and fracture.

What is Struthers' ligament?

A ligament that connects the medial epicondyle of the humerus to the supracondylar process.

What is a differential diagnosis related to the supracondylar process?

Osteochondroma, which can be sessile or pedunculated.

What is proximal radioulnar synostosis?

Osseous fusion of the proximal radius and ulna, which can be congenital or acquired.

What is the most common site of fusion in proximal radioulnar synostosis?

The proximal 1/3rd of the radius and ulna.

What is radial tuberosity pseudotumor?

An oval radiolucent-like lesion in the tuberosity of the radius that mimics a bone tumor.

What imaging findings are associated with a radial tuberosity pseudolesion?

A lucent pseudolesion in the radial tuberosity visible on a lateral radiograph of the elbow that disappears on the AP radiograph.

What population is commonly affected by radial tuberosity pseudolesion?

A 33-year-old female with medial elbow pain.

What is the maximum length of the supracondylar process?

Approximately 22mm.

What position does the supracondylar process point towards?

The elbow.

How is the supracondylar process typically characterized?

Usually asymptomatic.

What are the key structures involved in neural impingement due to the supracondylar process?

The median nerve.

What vascular structure may be impinged by the supracondylar process?

The brachial artery.

What types of tumors can mimic a radial tuberosity pseudotumor?

Bone tumors.

How can one differentiate between a true bone tumor and radial tuberosity pseudolesion?

The pseudolesion disappears on different radiographic views.

In what type of patients is proximal radioulnar synostosis often noted?

In congenital or rare cases.

What is the significance of identifying Struthers' ligament?

It is important for understanding nerve and vascular relationships at the elbow.

What imaging techniques are used for diagnosis in this lecture?

MRI and radiography.

What is the typical pathology associated with osteochondroma?

An abnormal growth on a bone that can be sessile or pedunculated.

What clinical symptom may lead to imaging for a radial tuberosity pseudolesion?

Medial elbow pain.

What are the common sites for osteochondromas?

Near the growth plates of long bones like the humerus.

What age group is often diagnosed with osteochondroma?

Typically occurs in children and adolescents.

What is the importance of differential diagnosis in assessing elbow lesions?

To correctly identify whether a lesion is benign or indicative of a more serious condition.

What key aspect of the supracondylar process can lead to misdiagnosis?

Its asymptomatic nature.

What does the term 'pseudocyst' imply about the radial tuberosity lesion?

It suggests that it resembles a cyst but is not a true cystic lesion.

What is a common imaging characteristic of a true bony tumor versus a pseudolesion?

True bony tumors typically do not disappear on different views.
