Abstract
Our aim was to evaluate the outcome in patients with bilateral non-simultaneous hip fracture treated with hemiarthroplasty at our institution between 1997 and 2003. We looked for any important modification factor that could change the devastating functional and social results.
Twenty-two patients with a mean age of 79 at the initial fracture and 82 at the subsequent fracture were evaluated; all were Garden grade III-IV. The second fracture happened a mean of 28 months after the first one.
The outcome measurement was the incidence of hip pain, recovery of pre-injury level of ambulation and activities of daily living at a minimum follow-up of one year. Following the first hemiarthroplasty patients deteriorated in their walking capacity and other activities of daily life, and this happened to an even greater extent after the second operation.
With respect to walking ability (measured in metres) we concluded that it improved if a modular hemiarthroplasty was used after both fractures (p<0.05) and that worse functional outcomes were observed when different kinds of hemiarthroplasties were used in the same patient.
