Introduction: Fractures of the proximal humerus (PHF) represent a common injury among orthopedic department; especially for three- and four-part fractures no consensus about the best treatment is still achieved. The aim of our study was to compare clinical and radiological outcomes in patients alternatively treated with plates and screws or external fixation system for a type III-IV proximal humerus fracture. Material and methods: Sixty-nine patients went surgery for type III-IV PHF between January 2011 and January 2014. According to the Neer classification, fractures were classified as type III in 50 cases (72,46%) and type IV in 19 cases (24,56%). 45 patients were treated with plates (65%) and 24 external fixators (35%). The patients’ mean age was 62 years (range, 31–87 y). At five years, 60 patients (86,9%) were assessed using the visual analog scale (VAS) pain score, Constant Score (CS), the range of motion, and radiological evaluation. The CS at five years was the primary outcome measure. Results were evaluated and compared with the contralateral unaffected side to avoid bias related to different ages. Results: At the final follow up, we found no clinical differences when comparing the two procedures. Moreover, when age was considered as a variable, a significative difference of the CS was observed in the group of patients younger than 65 years treated with a plate (Plate Group Mean: 79; SD: +/- 15. Ex Fi Mean: 58; SD:+/- 4. P = 0,008). In the group of patients older than 65 years, the two procedures did not show significative differences in outcomes (Plate Group Mean: 69; SD: +/- 15. Ex Fi Mean: 63; SD:+/- 7. P = 0,032). External fixation procedure was overall associated with a reduction in blood loss, surgical time, length of hospital stay. Conclusion: Percutaneous techniques have a long tradition in PHF treatment; the introduction of dedicated external fixation system has the advantage to improve the stability and allow early rehabilitation when compared to the classical pinning technique. In our experience, the indication elderly patients with osteoporosis and comorbidities may benefit by this type of mini-invasive surgery with low soft tissue damages.

Abstract

Introduction: Fractures of the proximal humerus (PHF) represent a common injury among orthopedic department; especially for three- and four-part fractures no consensus about the best treatment is still achieved. The aim of our study was to compare clinical and radiological outcomes in patients alternatively treated with plates and screws or external fixation system for a type III-IV proximal humerus fracture. Material and methods: Sixty-nine patients went surgery for type III-IV PHF between January 2011 and January 2014. According to the Neer classification, fractures were classified as type III in 50 cases (72,46%) and type IV in 19 cases (24,56%). 45 patients were treated with plates (65%) and 24 external fixators (35%). The patients’ mean age was 62 years (range, 31–87 y). At five years, 60 patients (86,9%) were assessed using the visual analog scale (VAS) pain score, Constant Score (CS), the range of motion, and radiological evaluation. The CS at five years was the primary outcome measure. Results were evaluated and compared with the contralateral unaffected side to avoid bias related to different ages. Results: At the final follow up, we found no clinical differences when comparing the two procedures. Moreover, when age was considered as a variable, a significative difference of the CS was observed in the group of patients younger than 65 years treated with a plate (Plate Group Mean: 79; SD: +/- 15.
