ObjectiveTo investigate the clinical effect of titanium elastic intramedullary nail(TEIN) on the treatment of adult radial neck fracture of Mason type Ⅱ. MethodsA total of 35 adult patients with radial neck fracture of Mason type Ⅱwere selected as subjects and were randomly divided into observation group (n=18) and control group (n=17). The observation group was treated with TEIN and the control group with manipulative reduction and plaster external fixation. The elbow joint movement function and elbow joint function score (Broberg-Morrey score) were compared between the two groups. ResultsAll of the patients were followed up for 12 to 18 months(the average was 16.2 months). In the observation group, reduction with the assistance of Kirschner wire was conducted in one patient during operation,and no open reduction and internal fixation was conducted in any cases. No cubitus varus and cubitus valgus were found in both groups. The flexion and extension degrees of elbow joint, pronation and supination degrees of forearm, and the Broberg-Morrey score in the observation group were superior to those in the control group (P＜0.05). ConclusionThe TEIN is a simple manipulation for treating adult radial neck fracture of Mason type Ⅱ, and has the advantages of less trauma and complications, and better overall effect. It is worth for clinical promotion and application.
