Conservative versus surgical treatment for displaced olecranon fractures in the elderly: a retrospective study and a review of the literature.

Background: Surgery is the gold standard treatment of displaced olecranon fracture, but it presents a high rate of complications, especially in the elderly, including wound breakdown and fixation failure. Conservative treatment of these fractures has recently been proposed with good functional outcomes. The aim of this retrospective study was to compare the functional results and level of satisfaction of displaced olecranon fractures which were managed surgically or conservatively in geriatric patients. The rate of implant removal and reoperation in the surgical group were also calculated.

Materials and methods: Sixteen and eleven patients aged ≥ 75 years (mean 83 and 86.2, respectively) with isolated Mayo IIA or IIB olecranon fracture were surgically and conservatively treated, respectively. All but 1 were females. Due to coronavirus pandemic, they were contacted by phone to validated clinical scores (QuickDASH, PREE and VAS), which were used to assess the outcome.

Results: At an average follow-up of 26.5 months in the conservative group and 53.1 in the surgical group (range 4-82), the mean Quick DASH was 11.67 and 11.2, respectively, while the mean PREE was 11.36 and 12.67, respectively. There was no significant difference in functional outcomes between the two groups, and all patients were satisfied. Seven complications occurred in the surgical cohort (33.3%), requiring reoperation in 4 cases (19%).

Conclusions: Displaced olecranon fractures can successfully be treated conservatively in low-demand geriatric patients with good functional results and high satisfaction rate.
