The Unusual Presentation Of Excessive Spurs Like Osteochondromas In An Adolescent With Hereditary Multiple Osteochondromas

Abstract

Hereditary Multiple Osteochondromatosis (HMO) is characterised by the presence of multiple osteochondromas, mainly affecting the long bones.
Osteochondromas are bony projections that are either sessile or pendulated in form. Isolated osteochondromas in the form of spurs have been
described as occurring in the knee and the foot. Reports of thorn-like osteochondromas affecting the ribs are extremely rare. We describe the unique
case of an adolescent with multiple osteochondromas affecting the long bones. While in the lower limbs they were noted to be sessile and
pendulated, they had the form of excessively elongated spurs in the radius. They created pain and limitation of his activities. The surgical removal
of these spurs enabled us to restore activity in the patient's dominant (right) arm
