Nine sites in three countries prospectively studied 69 displaced femoral neck fracture
patients treated with a new type of total hip reconstruction (TriboFit® Hip). 22 cases
were from the first author institution. The acetabular component consisted of a single
3 mm soft, pliable polycarbonate-urethane (PCU) polymer that was snap-fit directly
into the acetabular bone after minimal reaming of cartilage only and preparation of a
unique groove. The average age of these patients was 80,4 (range: 66-96), the sex
distribution was 55 females and 14 males, with 33 fractures of the left hip and 36
right. Of the 69 patients, 3 died of unrelated causes and 3 were lost to follow-up. Of
the 63 available for follow-up, all were followed for an average of 18 months (range: 6
to 44 months). The Harris Hip Score for a subset of these fractures patients was 79
at 12 months. Of the 63 followed, 4 (6,3%) were revised, 2 of which had dislodgment
of the acetabular component at 9 and 44 months. Of the revisions, 3 were from the
first four surgeries, all of which had instrumentation issues with this new technique.
One patients (1,6%) had a dislocation that was reduced non operatively at 15 days, 1
other (1,6%) became infected and 2 were bedridden. We believe the results with this
new type of prosthesis are encouraging and comparable to if not better than other
prosthetic options in the literature for this difficult-to-treat patient population.
