A total of 250 acute femoral neck fractures (244 patients) were operated using cemented
unipolar hemiarthroplasty (Lubinus sp II) in Central Finland Hospital, Jyväskylä
between 2007–2008. We retrospectively searched the patient records for
complications. Women composed 70 % (n=171) of the study population. The average
age of the women was 82,5 years and that of men 79,6 years. All operations
were performed using posterior approach. We found 29 (11,6 %) complications in
28 patients during mean follow-up of 4 years. There were 12 dislocations (4,8 % of
all patients), 3 (1,2 %) periprosthetic fractures, 2 (0,8 %) super! cial wound infections,
5 (2,0 %) deep (prosthetic) infections, 1 (0,4 %) protrusions of the prosthesis, 2
(0,8 %) intraoperative iatrogenic fractures, 2 (0,8 %) paralysis of the peroneal nerve
and 2 (0,8 %) conversions to total hip artroplasty (THA) due to groin pain. A conversion
to THA for any reason was performed in 9 cases (3,6 %) and revision surgery
was required in 14 (5,6 %) cases. Complication rate in our hospital is at par with the
level described in international literature. The need for conversion to THA and revision
surgery is low.
