Aneurysmal bone cysts (ABC) mainly occur in the long bones but only rarely in the bones of the feet. This study reviews the 25-year experience of a tertiary orthopaedic oncology referral center treating ABC's in the bones of the feet, using prospectively collected data to document their incidence, treatment and the outcome.


Information on the diagnosis, treatment, complications and outcomes were collected for all eligible patients from our prospectively collected database. Radiologic healing was used as our primary outcome measure. Cases were considered to have failed treatment if there was progression of the lesion that needed further treatment.


Of 273 patients with ABC, 16 patients (5.9%) were found to have their lesions in the foot. There were ten female and six male patients, aged from 4 to 52 (mean, 18.2) years. The metatarsals were the most commonly affected site (44%). Curettage of the lesion without additional adjuvant measures (14 of 16 patients) was sufficient for the treatment in 11 of 14 patients (79%). This gave a recurrence rate of 21% (three of 14 patients) in those treated by curettage alone and 19% (three of 16 patients) if the whole cohort is considered.


Although relatively rare, there is no reason to assume that ABCs of the feet will respond to treatment or recur any differently from ABCs that occur elsewhere in the body. Our experience has been that surgical curettage alone is sufficient to treat most ABCs of the feet.
