Prominence of the calcaneus

Description: Undue prominence of the posterosuperior edge of the calcaneal tuberosity can lead to mechanical irritation by footwear, and to painful bursitis. Haglund (1927) recommended radical resection of this part of the calcaneus when conservative treatment failed, but there is uncertainty about the amount of bone which should be removed.
The aim of surgery is to produce a gently sloping, smooth surface above the level of the insertion of the Achilles tendon which does not make contact with the tendon
