Solitary Bone Cyst: What to Do When Conservative Treatment Has Not Worked
For patients with a solitary bone cyst, conservative management is typically the first step. When that approach fails to achieve the expected outcomes, escalation to a more active intervention is indicated. This protocol describes the clinical pathway taken at that point.
The preceding approach — conservative treatment with observation, and immobilization for uncomplicated pathological fracture — is considered to have failed when any of the following applies: fracture healing is not achieved within six weeks of a pathological fracture; clinical symptoms persist without stabilisation; or the cyst shows continued radiographic progression.
Once conservative care has failed, a direct surgical approach to the cyst becomes appropriate. The treatment goal is complete healing of the bone cyst confirmed on radiograph. The full protocol — including the specific procedure, site-specific indications, and follow-up criteria — is available via the link below.

- Intralesional curettage with filling up the resulting cavity with bone substitute is a common surgical procedure in case of a symptomatic SBC and an alternative treatment to simple observation.
- Curettage and defect reconstruction with bone substitute in cases without pathological fracture are performed due to pain under weight bearing in the lower extremity and due to the prevention of frequent fractures of the humerus in the upper extremity.
- After intralesional curettage and defect reconstruction with bone substitute complete healing of the cyst can be observed in one-third of the cases.
