Abstract
Background
Our hypothesis was that minimally invasive plate osteosynthesis (MIPO) using long philos plate (LPP) would show better clinical and radiological outcomes and less complications than narrow locking compression plate (NLCP) for spiral humerus shaft fractures with or without metaphyseal fracture extension.
Methods
From January 2009 to May 2016, we retrospectively studied 35 patients who underwent MIPO for spiral humerus shaft fractures with or without metaphyseal fracture extension (AO classification 12 A, B, C except A3). Eighteen patients underwent MIPO with a 4.5 mm NLCP (group I) in the early period of this study, while 17 patients underwent MIPO with LPP (group II) in the later period. Range of motion (ROM), pre- and post-operative anteroposterior (AP) and lateral angulation of the fracture, operation time, amount of bleeding, and functional outcomes including American Shoulder and Elbow Surgeons score, University of California at Los Angeles score, and Simple Shoulder Test score were analyzed at the final follow up.
Results
All patients had complete bony union and achieved satisfactory functional outcomes except 2 patients. In LPP group, better outcomes in postoperative fracture angulation on X-ray and operation time (p < 0.05) were shown. But, two revision surgery with NLCP and bone graft was performed owing to 2 metal failures.
Conclusions
In spiral humeral shaft fractures, LPP group showed better fracture reduction on X-ray and shorter operation time except metal failure owing to weak fixation. Even though MIPO technique using LPP is easier and more accurate reduction method, rigid fixation should be considered.
