Abstract

Background

Controversy exists regarding the best treatment of proximal humerus fractures in the elderly. Recent studies of open reduction and internal fixation have demonstrated high complication rates.

Questions/purposes

We asked whether (1) open reduction and internal fixation could be performed with low rates of immediate and delayed complications, (2) reduction of these fractures could be maintained over time by evaluating long-term radiographs and visual analog pain scores, and (3) 6-week immobilization would lead to disabling stiffness by evaluating postoperative motion and functional scores.

Patients and Methods

We retrospectively reviewed all 35 patients older than 75 years with displaced proximal humerus fractures treated using a “hybrid” technique between 2002 and 2008. All patients were immobilized for 6 weeks after surgery. Thirteen of the 35 patients either died or developed severe dementia during followup. The analysis included 22 patients followed a minimum of 1 year (mean, 3 years; range, 1–6.7 years).

Results

There were no early or late reoperations in this series. An acceptable reduction was achieved in 89% of the shoulders and maintained over time. All fractures healed. Osteonecrosis was noted on radiographs in 11% of the shoulders. Six weeks of immobilization did not lead to disabling stiffness. At most recent followup, mean active elevation was 141°, mean active internal rotation L1, mean active external rotation 36°, and mean American Society of Shoulder and Elbow Surgeons score 68.

Conclusions

Utilizing this approach, open reduction and internal fixation followed by 6-week immobilization results in a low rate of reoperation and good functional outcomes for elderly patients with proximal humerus fractures.
