Abstract
A series of 76 distal tibial pilon fractures treated with surgical fixation were retrospectively reviewed from case notes, plain radiographs and CT imaging. Patient demographics, injury and fracture patterns, methods and timing of fixation and clinical and radiological outcomes were assessed over a mean follow up period of 8.6 months (range 2–30).
Definitive fixation was most commonly performed through an open technique (71 cases) with plate fixation. CT imaging was used to plan the most direct approach to access the fracture fragments. Single or double incision techniques were used to access the tibia, with fixation of the fibular performed when necessary.
Superficial infection occurred in 5 cases (6.9%) and deep infection in 2 (2.8%). Aseptic wound breakdown occurred in 5 cases (6.9%). The rate of wound breakdown after three-incision technique was 37.5%.
There were 10 cases of non-union (13.9%) and 8 of mal-union (10.5%). Post-traumatic arthritis was present on the most recent x ray in 17 cases (23.4%). Further surgery was required in 20 cases (27.8%), most commonly for metalwork related problems and also for treatment of non-union, post-traumatic arthritis and infection.
This review gives comprehensive injury specific and surgical outcome data from one of the largest reported series of these complex and problematic injuries.
