Aims

To identify a core outcome set of postoperative radiographic measurements to assess technical skill in ankle fracture open reduction internal fixation (ORIF), and to validate these against Van der Vleuten’s criteria for effective assessment.

Introduction. Fixation of posterior malleolar fragments associated with ankle fractures aims to stabilise the syndesmosis and prevent posterior subluxation. Haraguchi described 3 types of posterior malleolar fractures, with type 2 being a medial extension injury, these fractures often involve medial and posterior fragments. We describe the techniques and outcomes for a double window posteromedial approach allowing optimal reduction and stabilisation. Methods. A retrospective review was performed at 2 units, Bristol Royal Infirmary and QE Hospitals Birmingham, between August 2014 and April 2016. Inclusion criteria were all patients having this posteromedial approach for closed ankle fracture fixation. Patients were assessed for complications and postoperative ankle function with the Olerud and Molander scoring system. Results. We identified 9 patients treated over an 18 months with average follow up 9 months (range 4–18 months). All had an ankle dislocation reduced on scene or in ED, with 5 having posterior subluxation of the talus on the original films. None were open injuries. All had fixation of a posteromedial malleolar fragment, with 7 requiring a further direct lateral incision. Olerud and Molander ankle function score averaged at 72 (range 60–85) at short term follow up. Discussion. Approaches to the posteromedial fragments have been previously described in 2 ways. One utilises a window just medial to the Achilles tendon taking the neurovascular bundle medially, while the other approaches between tibialis posterior and FDL taking the neurovascular bundle laterally. Neither delivers complete access to an injury that often has sagittal and coronal splits needing individual reduction and fixation. Our approach over the neurovascular bundle allows 2 safe corridors through a single incision facilitating fragment specific fixation of both the medial and posterior components of the injury. Early results suggest this to be a safe and reliable technique to reduce and stabilise complex posteromedial ankle fractures

Objectives

The surgical challenge with severe hindfoot injuries is one of technical feasibility, and whether the limb can be salvaged. There is an additional question of whether these injuries should be managed with limb salvage, or whether patients would achieve a greater quality of life with a transtibial amputation. This study aims to measure functional outcomes in military patients sustaining hindfoot fractures, and identify injury features associated with poor function.
