[A long-term follow-up of treatment of adult unicameral bone cysts with allograft of lyophilized cancellous bone].

Abstract

OBJECTIVE:

To investigate the long-term clinical results of treatment of adult unicameral bone cyst with cancellous allograft.

METHODS:

From 1993 to 1998, 15 patients with unicameral bone cyst were treated by allograft with lyophilized cancellous bone. Among 15 patients, there were 5 males and 10 females, aging 19-41 years with an average of 27 years. The average follow-up time was 7.5 years (6-11 years). The X-ray films were taken and the CT scanning were carried out.

RESULTS:

The X-ray films showed that the allograft particles became vague 2-3 months after operation, that the allograft particles fused and began to form new bone and the bone density increased 5 months after operation, and that new bone formation completed after 7 months of operation. At the end of follow-up, remodelling in new bone occurred. Recurrence was not found in all patients. The symptom of pain disappeared or relieved obviously.

CONCLUSION:

Allograft of lyophilized cancellous bone is an effective treatment for adult unicameral bone cysts.
