| Summary: | Purpose. To review the outcome after intralesional curettage without bone grafting for simple bone cysts in the capitate. Methods. Records of 12 hands in 10 consecutive females aged 14 to 21 (mean, 17.5) years who underwent intralesional curettage without bone grafting for a simple bone cyst in the capitate were reviewed. Clinical outcome was evaluated using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Wrist/hand pain was assessed using the modified Mayo wrist score. Patient satisfaction, range of motion, and grip strength were self-evaluated as improved, unchanged, or worse. Results. After a mean follow-up of 7.5 (range, 2.5–12.5) years, the mean DASH score was 12.3 (range, 0–25), and the mean modified Mayo wrist score was 85 (range, 70–95); the modified Mayo wrist score was excellent in 8 hands and good in 4 hands. All patients had bone union and preservation of capitate height. All patients had no pain except for 2 patients (4 hands) who reported pain after strenuous activity. All patients had improved range of motion, and all but 2 patients had improved grip strength. Conclusion. Curettage without bone grafting for a simple bone cyst in the capitate is a sufficient and viable option.
