To investigate the effectiveness of a decision-based protocol designed to minimise the use of medial incisions when performing crossed-wire fixation of supracondylar fractures of the distal humerus whilst minimising ulnar nerve injury. We have employed a protocol for placing the medial wire during crossed k-wire fixation of supracondylar fractures dependent upon the medial epicondyle. When this is palpable, the wire is introduced percutaneously; when it is not, a mini-incision is made. All cases of closed reduction and crossed K-wiring of supracondylar fracture over a three year period (2008–2011) were identified from our department database. Cases with a neurological injury identified pre-operatively, and those in which the protocol had not been followed were excluded. Casenotes were reviewed to determine the incidence and outcomes of post-operative ulnar nerve deficit.Aim
