Macrodactyly of the foot is a rare but disabling
condition. We present the results of surgery on 18 feet of 16 patients, who
underwent ray amputation and were followed-up for more than two
years at a mean of 80 months (25 to 198). We radiologically measured the intermetatarsal width and forefoot
area pre-operatively and at six weeks and two years after surgery.
We also evaluated the clinical results using the Oxford Ankle Foot
Questionnaire for children (OxAFQ-C) and the Questionnaire for Foot
Macrodactyly. The intermetatarsal width and forefoot area ratios were significantly
decreased after surgery. The mean OxAFQ-C score was 42 (16 to 57)
pre-operatively, improving to 47 (5 to 60) at two years post-operatively
(p = 0.021). The mean questionnaire for Foot Macrodactyly score
two years after surgery was 8 (6 to 10). Ray amputation gave a measurable reduction in foot size with
excellent functional results. For patients with metatarsal involvement,
a motionless toe, or involvement of multiple digits, ray amputation
is a clinically effective option which is acceptable to patients. Cite this article:
