Three randomized control trials with a total of 130 patients were pooled in this meta-analysis to compare non-operative treatment methods versus open reduction and internal fixation for proximal humerus fractures in the elderly. No differences were found in Constant Scores, nonunion rate, risk of avascular necrosis of the humeral head or osteoarthritis. The results of this study do not encourage the surgical treatment for older patients with fractures of the proximal humerus.

The Reporting Criteria Assessment evaluates the transparency with which authors report the methodological and trial characteristics of the trial within the publication. The assessment is divided into five categories which are presented below.

The Fragility Index is a tool that aids in the interpretation of significant findings, providing a measure of strength for a result. The Fragility Index represents the number of consecutive events that need to be added to a dichotomous outcome to make the finding no longer significant. A small number represents a weaker finding and a large number represents a stronger finding.
Why was this study needed now?
Six percent of all fractures treated in the emergency department are proximal humeral fractures and the majority can be successfully treated without surgery. These fractures are the most common type of fracture occurring in elderly patients and 13 to 16% are comminuted, displaced and categorized as 3- and 4-part fractures according to the Neer Classification. Controversy lies in the whether comminuted displaced fractures in elderly patients with osteoporosis who experienced low energy trauma should be treated with surgery or not. A select number of randomized control studies compare open reduction and internal fixation to conservative methods and this meta-analysis was brought forward to pool the data from the trials available to re-evaluate the use of both treatments.
What was the principal research question?
Are comminuted displaced humeral fractures in elderly patients best treated with open reduction and internal fixation or non-operative treatments?
What were the important findings?
- All three studies (n=130) examined Constant score and the outcomes were similar between surgical and nonsurgical treatment groups (WMD 20.51, 95% CI: 27.25 to 6.22, P= 0.88, I squared = 0%).
- The 3 studies found nonunion was uncommon in both groups and that the difference between the two was insignificant (RR =0.78; 95% CI: 0.18–3.41, P= 0.74, I squared = 0%).
- In the 3 RCT's examined, no difference was found in the risk of avascular necrosis of humeral head (RR = 0.86; 95% CI: 0.46–1.58, P= 0.62, I squared =0%).
- 2 of the studies (82 patients) reported data on osteoarthritis and neither treatment arm provided additional benefits (RR = 1.34; 95% CI: 0.37–4.82, P= 0.66, I squared =0%).
What should I remember most?
No benefits were found regarding constant score, nonunion rate, risk of avascular necrosis of the humeral head or osteoarthritis with open reduction and internal fixation over nonsurgical methods. Both nonunion rates and risk of avascular necrosis were low in each group.
How will this affect the care of my patients?
This meta-analysis of 3 randomized control studies suggests non-operative treatment should be used for 3- and 4-part proximal humeral fractures in elderly patients over open reduction and internal fixation, as there is no additional benefit of the operative treatment. This study was limited by the modest quantity of studies and few clinical outcomes observed.
