The use of NSAIDs for postoperative pain management following orthopaedic surgery or during conservative treatment of fractures is controversial. Experimental animal models suggest NSAIDs inhibit bone healing. In a review of the literature, there was no clinical evidence to support categorical discard of NSAID for postoperative pain relief in uncomplicated cases. However, NSAID should be considered a potentiel risk factor of impaired bone healing and avoided in patients with a high risk of pseudoarthrosis. Recommended daily doses should be respected and duration of treatment should be limited.
