Late sequelae of secondary Haglund's deformity after malunion of tongue type calcaneal fracture: report of two cases.

We are reporting two cases of calcaneal fractures with posterior heel pain due to a prominent superior calcaneal tuberosity impinging on the Achilles tendon after a tongue type fracture. Malunion of the tongue fracture fragment resulted in the symptomatic bony prominence, which we defined as the secondary Haglund's deformity. Both cases were treated with resection of the superior calcaneal tuberosity when symptoms continued after non-surgical treatment. Clinical results after operations were both satisfactory with complete pain relief.
