Ankle fractures: Getting it right first time

Ankle fractures are common injuries presenting to trauma departments and ankle open reduction and internal fixation (ORIF²) is one of the first procedures targeted in early orthopaedic training. Failure to address the fracture pattern with the appropriate surgical technique and hardware may lead to early failure, resulting in revision procedures or premature degenerative change. Patients undergoing revision ORIF are known to be at much greater risk of complications and many of these secondary procedures may be preventable.

A retrospective analysis of all patients attending our unit for ankle ORIF over a two year period was undertaken. Patients were identified from our Bluespier database and a review of x-rays was undertaken. All patients undergoing re-operation within eight weeks of the primary procedure were studied. The cause of primary failure was established and potential contributing patient and surgical factors were recorded.

236 patients undergoing ankle ORIF were identified. 13 patients (5.5%) returned to theatre for a secondary procedure within eight weeks. Within this group, seven (54%) patients returned for treatment of a neglected or under treated syndesmotic injury, three (23%) for complete failure of fixation, two (15%) with wound problems and one (8%) for medial malleolus mal-reduction. Of the patient group, five (39%) were known type 2 diabetics. Consultants performed two (15%) procedures, supervised registrars five (39%) and unsupervised registrars six (46%) operations.

Errors are being made at all levels of training in applying basic principles such as restoring fibula length and screening the syndesmosis intra-operatively. Appropriate placement and selection of hardware is not always being deployed in osteopenic bone resulting in premature failure of fixation and fracture patterns are not being fully appreciated. Patients are undergoing preventable secondary procedures in the operative treatment of ankle fractures.
