An exostosis is a bony growth projecting from the surface of a bone. The most clinically significant exostoses are osteochondromas (also called osteocartilaginous exostoses) — the most common benign bone tumour, accounting for approximately 35% of all benign bone tumours. Osteochondromas consist of a bony stalk capped by a layer of cartilage, histologically continuous with the underlying bone cortex and medullary canal. They arise most commonly around the knee (distal femur, proximal tibia, fibula), the shoulder (proximal humerus), the pelvis, and the ribs, and typically present in childhood or adolescence — growing until skeletal maturity, after which they should be static.
Other types of exostoses include: subungual exostosis (a painful bony growth beneath the toenail or fingernail, most commonly the great toe, causing nail deformity and pain from shoe pressure); reactive bone spurs (at the heel — Haglund's deformity, plantar fasciitis-associated calcaneal spur; at the elbow — olecranon spur); and exostoses of the external auditory canal from repeated cold-water swimming (surfer's ear).
Surgical excision provides definitive treatment for symptomatic exostoses — removing the lesion with a complete cartilage cap (to prevent recurrence) and sending the specimen for histopathological confirmation.
Osteochondroma and When Surgery is Needed
Osteochondromas are classified as solitary (the vast majority — sporadic, no genetic basis) or multiple (hereditary multiple exostoses — HME, an autosomal dominant condition caused by mutations in the EXT1 or EXT2 genes, in which the patient develops dozens to hundreds of osteochondromas throughout the skeleton). HME is associated with a higher lifetime risk of malignant transformation (secondary chondrosarcoma) — estimated at 0.5–5% — and requires long-term orthopaedic surveillance.
Solitary osteochondromas are almost universally benign — malignant transformation to chondrosarcoma occurs in less than 1% of solitary lesions. Concerning features suggesting possible malignant transformation include: growth after skeletal maturity; a cartilage cap thickness greater than 2 cm on MRI (the cap should thin progressively as the patient matures); cortical destruction or soft tissue invasion; and new pain in a previously painless lesion.
Most osteochondromas require no treatment if asymptomatic — annual observation is appropriate. Indications for surgical excision include: pain from mechanical irritation of adjacent tendons or bursae (a bursa often forms over the prominent cap — this is the "exostosis-associated bursitis" that causes most symptoms); deformity (the osteochondroma distorts the adjacent bone — a common problem in the forearm and leg in HME); restricted joint range of motion; neurovascular compression; or concern about malignant transformation.
Exostosis Excision Procedure
Exostosis excision is performed under general or regional anaesthesia. The approach depends on the location: a direct approach over the palpable lesion through a skin incision over the bony prominence, with appropriate muscle retraction. The periosteum overlying the exostosis is incised and reflected; the base of the stalk is identified at its junction with the cortex of the underlying bone.
The excision must include the complete cartilage cap — which extends circumferentially around the stalk and is the regenerative tissue responsible for recurrence if left behind. The stalk is osteotomised flush with the bone surface using an osteotome and mallet or an oscillating saw; the surface is smoothed with a bur; the wound is irrigated and closed.
The specimen — including the stalk, cartilage cap, and perichondrium — is sent for histopathological analysis. The cartilage cap thickness, the interface between cap and stalk, and the cellular characteristics of the chondrocytes are assessed to exclude any transformation toward chondrosarcoma.
For small exostoses (subungual, small osteochondromas), local anaesthesia may suffice. For large, deeply located exostoses (pelvis, posterior shoulder, posterior knee), general anaesthesia and specialist positioning may be required.
Procedure Steps
- X-ray and MRI assessment of exostosis; cartilage cap thickness measured; concerning features assessed
- Surgical approach planned based on location; neurovascular structures mapped
- General or regional anaesthesia; tourniquet for peripheral limb lesions
- Approach over the lesion; periosteum reflected
- Osteotomy flush with the bone surface; complete cartilage cap removal confirmed
- Bone surface smoothed with bur; wound irrigated and closed in layers
- Specimen sent for histopathology; report reviewed at 48–72 hours

Osteochondroma excision in the USA costs $5,000–$12,000. In India, excision of a peripheral osteochondroma (knee, shoulder, forearm) costs $1,500–$3,000; large or deeply located exostoses requiring more complex surgery cost $3,000–$5,000. All excision specimens are sent for histopathology at India's partner centres.
Recovery & Follow-up
Recovery depends on the location and size of the excision. Small peripheral exostoses: walking the same day; normal activity within 1–2 weeks; return to sport at 4–6 weeks. Large or complex excisions: physiotherapy and rehabilitation tailored to the muscle groups involved; return to full activity at 6–12 weeks. Wound healing: sutures removed at 10–14 days; the surgical scar fades over 12 months. Histopathology results are communicated within 72 hours.
Recovery Tips
- Keep the wound clean and dry for 48 hours after surgery
- Elevate the operated limb for the first 48–72 hours to reduce swelling
- Begin gentle range of motion exercises of the adjacent joint as instructed by the physiotherapist
- Report any return of pain or new swelling at the surgical site — very rare early recurrence warrants MRI review
- Patients with hereditary multiple exostoses should continue annual radiological surveillance of the full skeleton
Risks & Complications
Exostosis excision risks include: recurrence (from incomplete removal of the cartilage cap — low with careful complete excision); wound healing problems; nerve or vessel injury near the excision site; haematoma; and (very rarely) stimulation of growth of adjacent bone in young patients whose growth plates are still open. The most important long-term concern is histopathological confirmation of benign pathology — all excised specimens are sent to pathology.
Why GAF Healthcare
GAF Healthcare connects patients with orthopaedic surgeons who have experience in bone tumour surgery and understand the importance of complete cartilage cap excision in preventing recurrence. All excised specimens are sent to pathology as standard, and the result is communicated to the patient within 72 hours. For patients with hereditary multiple exostoses, we coordinate with both orthopaedic surgery and clinical genetics for comprehensive management.
Frequently Asked Questions
Will my exostosis grow back after surgery?
If the cartilage cap is completely excised, the recurrence rate is very low (approximately 2–5% for most peripheral exostoses). In young patients who have not reached skeletal maturity, the base may show some periosteal reactive bone formation that can look like early recurrence on X-ray — MRI distinguishes this from a true recurrence. In hereditary multiple exostoses, new exostoses continue to arise from other sites (not a recurrence at the surgical site), requiring ongoing surveillance.
Do all osteochondromas need to be removed?
No. Asymptomatic, stable osteochondromas that are not causing any functional problem do not need to be removed. Regular observation with clinical examination and intermittent X-rays (every 2–3 years in children, or if any change is noticed) is appropriate. Surgical excision is indicated only when the lesion causes pain, deformity, mechanical restriction, neurovascular compression, or when worrying features suggesting possible malignant transformation are identified.
Is there a risk that my osteochondroma will become cancerous?
For solitary osteochondromas, the risk of malignant transformation to chondrosarcoma is less than 1% — very low. For hereditary multiple exostoses, the lifetime risk of any lesion transforming is estimated at 0.5–5%. The features that should prompt urgent MRI and orthopaedic oncology review are: growth of the lesion after skeletal maturity; new pain in a previously painless lesion; cartilage cap thickness greater than 2 cm on MRI; and cortical destruction or soft tissue invasion.
