Abstract

We describe 2 men with seronegative rheumatoid arthritis who presented non-union of bone after osteotomy of the tibia in one case and of a metatarsal bone in the second. Both patients were still being treated with oral low doses of methotrexate (MTX). After MTX was stopped, a prompt healing of the bone occurred. These observations suggest that MTX should be stopped temporarily in cases with delayed bone healing after surgery.
