STUDY.

Treatment with osseointegrated transfemoral amputation prostheses (OI-prostheses)
has been performed in Sweden since 1990. It comprises two surgeries and
rehabilitation with a total treatment period of 12-18 months. In 1999 a prospective
study named OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees)
was started with the aim to report outcome at 2-years following the second surgery.
Among the rehabilitation details prosthetic mobility and health related quality of life
(HRQL) are assessed. The study includes 55 implants on 51 patients, with 4 patients
treated bilaterally. Some preliminary results have previously been reported on
subsets of the material. Those include statistically significant improved general and
specific HRQL among the first 18 consecutive treated patients and decreased
walking energy cost and increased walking habits among 20 patients with unilateral
transfemoral amputation. In June 2010 all included patients will have been followed
for 2 years and analyses of definitive results can be started. In January 2010 a total
of 42 patients with 46 implants (50% male, 50% female, mean age 44 years (Sd
12,9), cause of amputation; 62% trauma, 29% tumour, 9% other) had passed the 2year
follow-up. Preoperatively 17% did not use any prosthesis and 60% reported
daily prosthetic use. At 2-years follow-up 7% did not use prostheses at all and 87%
reported to use the OI-prosthesis daily. Final outcome from the OPRA study will be
reported during 2010. Preliminary results indicate that treatment with transfemoral OIprosthesis
improve prosthetic mobility and HRQL.
