Abstract
Introduction: The avulsion fractures of the calcaneal tuberosity represent a rare model of injury that is caused by a powerful tension force of the Achilles tendon associated or not to direct shock to the calcaneusCase report: We report a case of direct trauma to the heel on the edge of the swimming pool at the sport stroke of swimming.Percutaneous reduction by bone reduction forceps under fluoroscopy fluoroscopy with osteosynthesis by two percutaneous cannula screws on Kirchner wires. Equine cast immobilization after removal of the threads. Good clinical and functional radiological evolution.Conclusion: The percutaneous screw under fluoroscopy is the best technique with good results anatomical and functional and aesthetic.

But with a good prognosis, is a duckbill fracture of the posterior tuberosity, called avulsion of the insertion of the Achilles tendon.These injuries are usually caused by a violent concentric contraction of the gastrocnemius muscle complex after loss of balance or a fall. [1,2,3] Proximal displacement of the avulsed fragment of the postero-superior part of the calcaneal tuberosity leads to functional incapacity of the gastrocnemius-soleus complex and may result in skin necrosis due to the pressure of the fragment on the skin above the heel. [4, 5] The fragments vary in size and usually include the complete insertion of the Achilles tendon [1]
Summary
The tarsus is often exposed to severe trauma with high morbidity and disability associated with displaced intraarticular fractures. But with a good prognosis, is a duckbill fracture of the posterior tuberosity, called avulsion of the insertion of the Achilles tendon.These injuries are usually caused by a violent concentric contraction of the gastrocnemius muscle complex after loss of balance or a fall. [4, 5] The fragments vary in size and usually include the complete insertion of the Achilles tendon [1] They can extend into the subtalar joint and even present as open beak fractures. [8] Surgical management of avulsion fractures of the calcaneal tuberosity is generally indicated for open fractures, severe skin involvement and displaced fractures [1,2,3,4,5]
