The indication for minimally invasive plate osteosynthesis (MIPO) may include articular fractures depending on the fracture pattern. The goal of this study was to evaluate the feasibility of the MIPO technique for extra- and intra-articular distal humeral fractures.
The feasibility of the MIPO technique was assessed on 8 cadaveric elbows and 2 clinical cases. The four surgical approaches tested included a 20-mm ulnar incision, a 20-mm dorsoradial incision, and two incisions for olecranon osteotomy (A and B). Surgical incision A was 40 mm on the osteotomy level of the olecranon, and surgical incision B was an extension of the radial incision toward the osteotomy of the olecranon (80 mm). The four approaches were tested on 4 extra-articular (AO 13 A3) fractures and 4 intra-articular (AO 13 C3) fractures.
Reduction and plate fixation of all distal humeral fractures (8 cadaveric) with and without osteotomy was feasible. However, when using approach B, the soft tissue tension is reduced due to the wider incision. Nevertheless, both approaches A and B showed the same adequate intra-articular fracture control and reduction.
The MIPO technique for reduction and plate fixation in distal humeral fractures is feasible.
As a feasibility study, this study cannot be clearly classified into a level of evidence. It corresponds most closely to level IV.
