Extra-articular distal tibia facture (AO-43A): A retrospective study comparing modified MIPPO with IMN.

Abstract

We introduce a new MIPPO procedure which is simple and effective for the treatment of extra-articular distal tibia facture (AO-43A). The aim of this retrospective study was to compare our modified MIPPO with IMN. This retrospective study included 64 patients treated with our modified MIPPO and 61 patients with IMN. The data of sex, age, operation time, blood loss, wound complications, mal-reduction, shortening and fracture healing was analyzed. The operation time was significantly shorter in the MIPPO group than in the IMN group (56.0min vs. 85.0min, P<0.001). There were 5 patients (8.2%) in the IMN group and 2 patients (3.1%) in the MIPPO group who had wound complications (P=0.399). Mal-reduction occurred in 17 patients (27.9%) managed with IMN and in 3 patients (4.7%) who had MIPPO (P<0.001). Furthermore, no patients had a left/right difference in the length of the tibia of >1cm and nonunion in both groups. Our results have shown that our modified MIPPO has enormous advantages over IMN for extra-articular distal tibia fracture (AO-43A).
