Therapeutic effect of bone cement injection in the treatment of intraosseous ganglion of the carpal bones.

The aim of the present study was to treat intraosseous ganglia of the carpal bones with injectable bone cement grafting. Between January 2012 and December 2013, 4 patients (3 men and 1 woman) presenting with wrist pain and activity limitation were diagnosed with intraosseous ganglion of the carpal bones by radiography. The patients were treated with minimal invasive curettage and bone cement injection surgery. All patients were followed up for a mean time of 17 months (range, 12-22 months). The wrist pain was significantly reduced in all patients following surgery. In addition, the activity range and grip strength were also improved compared with the preoperative parameters. Subsequent to treatment, the Mayo wrist score and the Disabilities of the Arm, Shoulder and Hand score presented mean values of 78.8 (range, 75-80) and 11 (range, 7.7-15.0), respectively. These results suggested that the patients showed a good recovery. All patients were satisfied with the postoperative results and returned to work within 4 weeks. In conclusion, bone cement injection is an effective and safe therapeutic strategy for the treatment of intraosseous ganglia of the carpal bone.
