Fractura por avulsión de tipo II de la tuberosidad posterior del calcáneo (en pico de pato). Serie de casos

Abstract

BackgroundThe objective of the study is to know the incidence, the results of the surgery and the need for rehabilitation of type II avulsion fractures of the posterior tuberosity of the calcaneus. Materials and methodsAn observational study of a series of cases was carried out. We retrospectively reviewed all the calcaneal fractures diagnosed in our hospital in the last 12 years and selected the ones classified as avulsion fractures of the tuberosity of the calcaneus (duck beak). ResultsWe found 10 fractures with an avulsion fracture pattern of the calcaneal tuberosity (duck beak), which correspond to 4% of all the calcaneal fractures reviewed. All were treated by an open reduction and internal fixation. One case was treated urgently due to signs of suffering of soft tissue. Four cases presented post-surgical complications. Three cases required specific rehabilitation treatment. Usually, there is no a unique formula to establish a rehabilitation program after surgery. DiscussionIt is likely to expect an increase rate of this particular fracture according to that elderly population increase with associated osteoporosis and diabetes. The displaced fragment produced by the Achilles’ tendon may compromise scaring after surgery. Often a specific rehabilitative protocol is not needed.Evidence level. IV.
