Overview

If left untreated, patients with osteochondroma may progress to develop overlying bursitis, vascular compromise, and rise to malignant chondrosarcoma. Common complications of osteochondroma include fracture, osseous deformation, and growth arrest. Prognosis is generally regarded as good after surgical excision. The recurrence rate of osteochondroma is 2%.^[1]

Natural History

Most patients with osteochondroma are initially asymptomatic.
If left untreated, most of the patients with osteochondroma will develop palpable lump, overlying bursitis and malignant transformation.^[1]

Complications

Common complications of osteochondroma include:

Bone fracture
Growth arrest
Skeletal deformation

Prognosis

Osteochondroma prognosis is generally regarded as good, after surgical excision.^[2]
The overall recurrence rate after resection is 2%.^[1]
