The optimal technique and implant for fixation of multifragmentary fractures of the distal humeral shaft remain inconclusive. We describe the use of minimally invasive plate osteosynthesis (MIPO) via posterior approach and extra-articular distal humerus locking compression plate (LCP-EADH) fixation for 18 such fractures. All fractures were united with a mean union time of 17.6 weeks (range 12-20). Transient radial nerve palsy was demonstrated in 2 patients. Six patients had 5° varus angulation and 1 had 5° valgus angulation. Triceps power was Grade 5 in all patients. The mean arc of elbow motion was 127.5 degrees (range 115-140). Six patients had an excellent MEP score and 12 had a good MEP score. As the results, posterior MIPO and LCP-EADH fixation could be an alternative for multifragmentary fractures of the distal humeral shaft, particularly for fractures with a very short distal fragment.
