Patients may have a history of enchondroma or osteochondroma.

Osteochondroma is the most common benign bone tumor.

Some benign tumors are not true neoplasms, but rather, represent hamartomas, namely the osteochondroma.

Osteochondroma is a type of benign tumor that consists of cartilage and bone.

They are distinct from subungual osteochondroma.

Cancerous bone or soft tissue tumors (e.g. osteosarcoma, osteochondroma, fibrosarcoma, epithelioid sarcoma, Ewing's sarcoma, synovial sarcoma, sacrococcygeal teratoma, liposarcoma)

Examples of benign bone tumors include osteoma, osteoid osteoma, osteochondroma, osteoblastoma, enchondroma, giant cell tumor of bone, aneurysmal bone cyst, and fibrous dysplasia of bone.

This disorder is rare, and is characterised by an asymmetrical limb deformity due to localized overgrowth of cartilage, histologically resembling osteochondroma believed to affect the limb bud in early fetal life.

Ways in which they can be damaged include trauma (usually concussive), physical stress on the nerve, repetitious neck contraction, flexion or extension, and as a result of medical complications (such as osteochondroma, a benign tumour of the bone).

They also ruled out osteochondroma because the axis of the spur is 25 degrees relative to the vertical axis of the humerus, whereas an osteochondroma would have formed at 90 degrees to the axis of the humerus.
