Abstract
Introduction: The treatment of fractures of the proximal humerus is still controversial. Conservative treatment may result in severe disability due to malunion and shoulder stiffness. Open reduction and rigid fixation requires extensive soft tissue exposure, which may results in a high incidence of avascular necrosis of the proximal humerus. We present our experience with “minimal invasive” surgical techniques of such fractures.
Materials & Methods: This study consists of 128 Pts. (52 M, 76 F, 18–84 year old, mean 53.5Y) followed for 2–7 years (mean 3.5Y), treated by closed reduction and percutaneous pinning (55), by ORIF and minimal osteosynthesis by screws (27), by ORIF with rigid plates (7), and by hemiarthroplasty of the proximal humerus (39). Patients were evaluated by the Neer’s shoulder grading score and radiographs.
Results: Overall results were excellent and good in 85% of patients with 2, and 3 parts fractures of the proximal humerus treated by “minimal invasive” fixation techniques, with some better results in less comminuted fractures. 9/14 young patients with 4 part fractures had good functional results. The other 5 patients had poor results and 3 of them developed AVN of the humeral head. 75% of the patients treated by hemiarthroplasty had satisfactory results. They were almost free of pain, but most of them had only a moderate improvement in shoulder motion.
Discussion: Based on this study it seems that “minimal osteosynthesis” by K.W. techniques, lag screws or rush pins, by closed or open reduction, remains as the first optional treatment of complex fractures of the shoulder, even in young patients with a 4 part fracture. In the elderly, hemiarthroplasty should be considered in such pathology as the treatment of choice.
