Surgical Techniques

Surgical Excision of Exostosis

Complete removal of the bony protrusion including its cartilaginous cap. Performed through a direct incision over the lesion.

When it is used

Symptomatic lesions (pain, movement limitation, neurovascular compression) after individual assessment. Growth after skeletal maturity or suspicious features require specialist evaluation first, including orthopaedic oncology when indicated, rather than automatic simple excision.

Recovery

Variable based on location. Recovery at upper-limb sites is generally faster than at the lower limb, where a period of protected weight bearing may be needed. Times remain orientative.

Postoperative Overview

After a complete excision, including the cartilaginous cap, the risk of recurrence is low. Recovery depends on the location of the lesion and its relationship with nearby structures. The course described below is an indicative pathway, personalised after surgery.

Recovery Pathway (indicative)

Note: This is an indicative pathway, personalised after surgery. Some elements are relatively stable (goal of the procedure, approximate hospital stay, presence of a cast or brace); others depend on the individual case (weight bearing, range of motion, imaging, sport, hardware removal, follow-up intervals) and on the surgical technique chosen.

  1. Hospital stay

    Day-surgery in most cases.

  2. First weeks

    First weeks: relative rest and elevation of the limb as instructed.

  3. Second month

    Gradual return to usual activities. A short rehabilitation course may be useful if the lesion was close to a joint.

  4. Third month

    Resumption of full activity, verified at clinical follow-up.

  5. Return to sport

    Indicative pathway: return to sport generally occurs within a few weeks for the upper limb and somewhat later for the lower limb, depending on the site and the clinical picture.

  6. Follow-up

    A few scheduled checks after surgery. In isolated exostosis, long-term follow-up is selective: it is proposed according to the site, the completeness of the excision and the appearance of new symptoms.

Possible Complications

Rare: wound complications, injury to nearby nerves or vessels, recurrence if excision is incomplete.
