Simple Bone Cyst

Simple Bone Cyst

You should consult an orthopedic oncologist for a Simple Bone Cyst (SBC) or Unicameral Bone Cyst (UBC) because these specialists are experts in diagnosing and treating bone conditions. Although SBC is benign (non-cancerous), it can weaken the bone and lead to fractures or other complications. An orthopedic oncologist will accurately diagnose the condition, help monitor its progress, and provide the best treatment options, including surgical and non-surgical interventions.

A Simple Bone Cyst (SBC) or Unicameral Bone Cyst (UBC) is a benign (non-cancerous) bone lesion filled with fluid. These cysts are typically found inside the bones and are generally located in the long bones, such as the femur (thigh bone) or humerus (upper arm bone). UBCs are generally solitary (one cyst), and although they are not cancerous, they can cause the bone to become weak and more susceptible to fractures.

Simple Bone Cysts (SBCs) or Unicameral Bone Cysts (UBCs) most commonly affect children and adolescents between the ages of 3 and 14 years. The condition is less common in adults.

  • Humerus (upper arm bone)

  • Femur (thigh bone)

  • Tibia (shin bone)

  • Pelvis and spine can also be affected, but less frequently.

    • In many cases, SBCs/UBCs may not cause noticeable symptoms, and the cyst may be found incidentally during imaging studies for another issue. When symptoms do occur, they may include:

  • Swelling or tenderness at the site of the cyst.

  • It can make it harder to plan for later surgery if the cancer needs to be removed completely.

  • Fracture: The most common complication is a pathological fracture, meaning the bone becomes weakened by the cyst and may break more easily, often with minimal trauma.

    • The exact cause of Simple Bone Cyst (SBC) or Unicameral Bone Cyst (UBC) is not fully understood. It is thought to result from an abnormal development or failure of bone growth. While trauma or bone injury may sometimes be associated with the formation of the cyst, it is generally not considered the main cause. It’s believed that the cyst may form when fluid accumulates within the bone, possibly due to issues with blood supply or bone remodeling.

  • X-ray: The first step in diagnosing a simple bone cyst. It typically appears as a clear area in the bone, often surrounded by a thin border of bone.

  • MRI (Magnetic Resonance Imaging): An MRI provides more detailed images and can help assess the extent of the cyst and whether it affects surrounding soft tissues.

  • CT scan (Computed Tomography): This imaging tool is sometimes used for more detailed visualization of the bone structure.

  • Bone biopsy: In rare cases, a biopsy may be necessary to rule out other conditions if the cyst’s characteristics are unclear.

    • The treatment for Simple Bone Cyst (SBC) or Unicameral Bone Cyst (UBC) depends on the size and location of the cyst, as well as the severity of symptoms. Common treatments include:

  • Observation: If the cyst is small and not causing symptoms, it may simply be monitored over time with periodic imaging.

  • Curettage and bone grafting: This is a common surgical treatment where the cyst is scraped out (curettage), and the space is filled with bone grafts or synthetic bone materials to promote healing and prevent future fractures.

  • Steroid injection: Steroids can sometimes be injected into the cyst to help reduce the size of the cyst and prevent it from causing further problems.

  • Bone marrow/PRP injection: In some cases, bone cement may be injected into the cyst to fill the cavity and stabilize the bone.

  • Stabilisation – Stabilisation with TENS nail, plates/nail for lesions of proximal femur

    • Yes, there are non-surgical options for treating Simple Bone Cysts (SBCs) or Unicameral Bone Cysts (UBCs), particularly for smaller cysts that are not causing significant symptoms. These options include:

  • Observation: If the cyst is small and there are no symptoms, it may just be observed with regular imaging to ensure it is not growing.

  • Steroid injection: As mentioned, steroid injections can sometimes help shrink the cyst and reduce the risk of fractures, especially in younger patients.

  • Aspiration: In some cases, the fluid inside the cyst can be drained (aspirated) to reduce pressure and pain, although this may need to be repeated.

  • Accurately diagnose cancer in bones and soft tissues.

  • Make sure the biopsy is done safely, without spreading cancer or causing unnecessary damage.

  • Plan the best treatment for bone or soft tissue cancers after the biopsy results are in.
