Calcific spurs occur the calcaneal insertion of the Achilles tendon. They are seen in various rheumatic and articular diseases but also in physically active individuals. If symptomatic it is referred to as insertional calcific tendinopathy and may be present with or without calcific deposits in the main body of the tendon. It should be distinquished from Haglund deformity - a bony bump/lump that develops on the postero-superior aspect of the calcaneum away from the Achilles due to pressure from rigid-backed shoes eg basketball sneakers.
