Prospectively 15 consecutive osteoarthritis total hip patients were treated with a new
type of total hip reconstruction (TriboFit® Hip). The acetabular component consisted
of a 3 mm soft, pliable polycarbonate-urethane (PCU) polymer that was snap-fit
directly into the acetabular bone after minimal reaming of cartilage (6) or into a metal
shell (9).The average age was 75 in the no shell group and 72 in the metal shell
group. The female/male distribution was 4/2 in the no shell group and 8/1 in the shell
group. The left/right distribution was 1/5 in the no shell group and 6/3 in the shell
group. Of the 15 total patients, 2 could not be followed--1 patient in the no shell group
was unavailable because of a traumatic acetabular fracture shortly after surgery and
1 patient in the shell group died of mesenterial ischemia within a month of surgery.
The no shell group average time after surgery is 28 months and the shell group 21
months, giving an average of the two at 24 months. The Harris Hip Score for the no
shell group was 54 pre-operatively and 83 at 12 months. In the shell group, the Harris
Hip Score was 37 pre-operatively and 89 at 12 months. No patient was revised,
became dislocated, or developed an infection. The results to date appear to favor the
metal shell group, but a longer term follow-up with more patients is needed.
