Intermediate-term outcomes for floating elbow and floating elbow variant injuries.
BACKGROUND
There are limited outcome studies describing floating elbow injuries. The purpose of this report is to describe patient outcomes after floating elbow injury using the American Shoulder and Elbow Surgeons (ASES) elbow assessment form.


METHODS
From 1994 to 2004, 19 patients were retrospectively identified at 3 Level I trauma centers and returned for follow-up evaluation after treatment of their floating elbow injury. Patient outcomes were assessed based on physical examination and the ASES elbow form.


RESULTS
The 19 patients were evaluated at a mean of 6.7 years (range, 2.3-13.4 years) after treatment of their floating elbow injuries. The mean ASES elbow score was 89 (range, 13-99), and the mean visual analog scale satisfaction with elbow surgery was 8.7 (range, 7-10). Fifteen of 19 patients reported continued pain in the elbow. Patient age, arm dominance, type of humeral fixation, type of forearm fixation, open fracture, multiple surgeries, and fracture pattern were not significantly associated with outcomes. Nerve injury was associated with lower ASES elbow scores (P = .03). There was also a significant correlation between the ASES elbow score and follow-up time, indicating that patients with a longer duration of follow-up had better subjective outcomes (Spearman coefficient = 0.55; P = .02).


CONCLUSIONS
Floating elbow fractures represent high-energy trauma and have significant associated injuries. Nerve injury is correlated with lower subjective outcomes. Patients continue to improve for several years with acceptable mid-term results.
