Wrist Ganglia in Children: Nonsurgical Versus Surgical Treatment.

PURPOSE: To compare the outcomes of nonsurgical and surgical treatment of children with wrist ganglia.

METHODS: We performed a retrospective review of children with wrist ganglia treated at 2 separate institutions. In one, a clinic setting, children were treated with observation. In the other, a hospital referral center, children had surgical excision. Information obtained included persistent or recurrent cyst, and Quick-Disabilities of the Arm, Shoulder, and Hand measure. Patients aged 17 years or less at the time of cyst appearance with at least 1 year of follow-up were included.

RESULTS: We successfully contacted 90 patients: 50 in the nonsurgical and 40 in the surgical group. Average follow-up was 4.6 years. The persistence rate in the nonsurgical group was 52%. The recurrence rate in the surgical group was 15%. In the nonsurgical group, if a ganglion resolved, it did so within 18 months in 94% of patients. Dorsal ganglions persisted more often than volar ones (63% vs 33%). Older children had a higher rate of persistence than did younger children (58% vs 31%). For children aged 10 or less, surgery was associated with a recurrence rate of 17%, compared with 31% persistence in the nonsurgical group. For children aged 11 and more, surgery was associated with a recurrence rate of 15%, compared with 58% persistence in the nonsurgical group. There was no significant difference between Quick-Disabilities of the Arm, Shoulder, and Hand scores in any group.

CONCLUSIONS: In a child with a wrist ganglion, if the cyst ultimately resolved, it usually did so within 18 months. Dorsal ganglion cysts and ganglion cysts in older children have a higher chance of persisting. In children treated with surgical excision, we found a 15% recurrence rate.

TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
