Bone cyst: symptoms, diagnosis and treatment

A bone cyst is a lesion generally observed in the first two decades of life. Usual age of patients is between 5 and 15 years. It is more common in males. It consists of this cavity in the bone. The cavity is filled with yellowish clear liquid.

It is mainly located in the lower extremities or higher of the long bones such as the upper end of humerus or arm bonethe upper end of the femur or thigh femurtibia humeruslower end end bonelower or shin bone bonetalusforearm

The account of the upper end of humerus and femur for the majority of lesions.

The cystdiagnosis is by examination of rays x. sometimes an MRI may be necessary if the diagnosis is not clear x-ray.

Usually cyst does no problem until a fracture occurs. The fracture involves the cyst and usually occurs after trivial injury as the bone around the cyst is small.

Sometimes the fracture may also occur following some unusual activity. A cyst in the lower branch can present as a limp.

Healing of the fracture occurs quickly in a few weeks. The cyst becomes sometimes postmarked with the healing of the fracture. In such conditions, no further processing is necessary.

If the cyst remains after the healing of the fracture for treatment of the cyst can be launched. Treatment includes the following methods

Aspiration of cyst fluid and instillation of methylprednisolone injection in to the cavitySurgery of cyst

Instillation of methylprednisolone has a success rate of 70 to 80% in the cyst of healing. More than one instillation of methylprednisolone may be required. High levels of prostaglandins are present in cyst fluid. Methylprednisolone reduces these levels.

In the course of the cyst surgery is opened by an incision and the cyst lining is removed. After this, cyst is packed with bone chips. The surgery is performed if methylprednisolone instillation is unable to heal bone cysts.

A more recent treatment tried for this condition is the injection of the patients own bone marrow into the cyst. The first results by this method have shown be good.

Disturbance of growth is more likely to occur if the cyst extends beyond the growth plate. Is this patient surgery should be avoided, because it can cause trauma to the growth plate. Injection of methylprednisolone should be preferred.

What are the chances of recurrence after surgery?

25% of the reform of cyst after surgery.

What treatment is carried out in this condition?

Cyst is re-operated if it is deemed be increasing the size and the weakening of the bones significantly.
