Aim: To describe our experience in treating patients diagnosed with floating hip injury and to communicate the outcomes achieved and the rate of complications. A secondary aim is to compare the results of this group in terms of quality of life with those of patients presenting with a fracture either of the pelvis or of the acetabulum, but in which the femoral segment is not involved.
Patients and methods: This is a descriptive study of the patients diagnosed with floating hip injury (25 patients) who were treated at our hospital between 2004 and 2007, with a minimum follow-up of seven years. The results are compared with those of a control group of 56 patients diagnosed with an isolated pelvic or acetabular injury. We describe the injuries and the associated lesion. The patients' quality of life was assessed using the EUROQOL tool.
Results: Among the floating hip group of patients, three suffered an additional arterial lesion and were later treated with a supracondylar amputation. Seven patients presented heterotopic ossification. No significant difference was observed between the study and control groups, according to the EUROQOL tool, although the scores for every dimension were lower among the floating hip patients. Among the patients in the control group, the quality of life scores were also affected in every dimension of the EUROQOL scale.
Discussion and conclusions: The addition of a femoral fracture to a pelvic or acetabular injury, the so-called floating hip, is a devastating injury which has an important impact on patients' quality of life, going beyond that experienced by patients with isolated injuries. Nevertheless, our results did not reflect statistically significant differences in the quality of life among the three groups analyzed: isolated fractures, floating hip and floating hip resulting in amputation.
