Résumé

The best surgical management of displaced proximal humeral fractures remains a matter of considerable debate. This study presents mid-term functional outcome (median 4 years) after locking plate osteosynthesis for displaced proximal humeral fractures. Between February 2002 and December 2014 1031 patients with 1047 displaced proximal humeral fractures were treated by open reduction and locking plate fixation with the same implant and received consecutive prospective follow up at least 24 months after surgical treatment. Clinical follow-up consisted of Constant Murley score (CS), Disabilities of the Arm, Shoulder and Hand score (DASH), and Short Form 36 questionnaire (SF-36). Complete follow-up could be performed in 557 (53.2%) cases, with a mean follow-up of 4.0 ± 2.7 years. Of 557 patients (67% women; mean age at time of osteosynthesis: 68.3 ± 15.5 years) absolute CS of all patients 4 ± 2.7 years after surgery was 68.4 ± 20.3 points. Normalized CS according to Katolik was 80.4 ± 23.8 points, and CS in percentage to the contralateral side (%CS) was 87.2 ± 27.9%. DASH score was at 23.8 ± 20.8 points. Osteosynthesis related complications (secondary displacement, screw cutout, avascular necrosis (n = 117 patients) were associated with lower functional scores (mean CS was 54.5 ± 19.0 p.; nCS 64.5 ± 22.9 p.;%CS 71.2 ± 25.0%; DASH score 31.9 ± 22.4 p.). The SF 36 was 66.5 points in the case cohort and a vitality mean of 69.4 points. Patients with a complication showed lower results (SF 36 56.7; vitality mean 64.9 points). Overall, patients following locking plate osteosynthesis of displaced proximal humeral fractures showed good to moderate outcomes four years after surgery. Mid-term functional outcomes correlate significantly with those at 1 year postoperatively. Furthermore, there is a significant negative correlation of midterm functional outcome with the occurrence of complications. Level III, prospective nonconsecutive patients.

BACKGROUND BACKGROUND
The best surgical management of displaced proximal humeral fractures remains a matter of considerable debate. This study presents mid-term functional outcome (median 4 years) after locking plate osteosynthesis for displaced proximal humeral fractures.
METHODS METHODS
Between February 2002 and December 2014 1031 patients with 1047 displaced proximal humeral fractures were treated by open reduction and locking plate fixation with the same implant and received consecutive prospective follow up at least 24 months after surgical treatment. Clinical follow-up consisted of Constant Murley score (CS), Disabilities of the Arm, Shoulder and Hand score (DASH), and Short Form 36 questionnaire (SF-36). Complete follow-up could be performed in 557 (53.2%) cases, with a mean follow-up of 4.0 ± 2.7 years.
RESULTS RESULTS
Of 557 patients (67% women; mean age at time of osteosynthesis: 68.3 ± 15.5 years) absolute CS of all patients 4 ± 2.7 years after surgery was 68.4 ± 20.3 points. Normalized CS according to Katolik was 80.4 ± 23.8 points, and CS in percentage to the contralateral side (%CS) was 87.2 ± 27.9%. DASH score was at 23.8 ± 20.8 points. Osteosynthesis related complications (secondary displacement, screw cutout, avascular necrosis (n = 117 patients) were associated with lower functional scores (mean CS was 54.5 ± 19.0 p.; nCS 64.5 ± 22.9 p.;%CS 71.2 ± 25.0%; DASH score 31.9 ± 22.4 p.). The SF 36 was 66.5 points in the case cohort and a vitality mean of 69.4 points. Patients with a complication showed lower results (SF 36 56.7; vitality mean 64.9 points).
CONCLUSIONS CONCLUSIONS
Overall, patients following locking plate osteosynthesis of displaced proximal humeral fractures showed good to moderate outcomes four years after surgery. Mid-term functional outcomes correlate significantly with those at 1 year postoperatively. Furthermore, there is a significant negative correlation of midterm functional outcome with the occurrence of complications.
LEVEL OF EVIDENCE METHODS
Level III, prospective nonconsecutive patients.
