The orientation of the acetabular component can
influence both the short- and long-term outcomes of total hip replacement
(THR). We performed a prospective, randomised, controlled trial
of two groups, comprising of 40 patients each, in order to compare
freehand introduction of the component with introduction using the transverse
acetabular ligament (TAL) as a reference for anteversion. Anteversion
and inclination were measured on pelvic radiographs. With respect to anteversion, in the freehand group 22.5% of the
components were outside the safe zone With respect to inclination, in the freehand group 37.5% of the
components were outside the safe zone The transverse acetabular ligament may be used to obtain the
appropriate anteversion when introducing the acetabular component
during THR, but not acetabular component inclination. Cite this article:
Revision of a cemented hemiarthroplasty of the
hip may be a hazardous procedure with high rates of intra-operative complications.
Removing well-fixed cement is time consuming and risks damaging
already weak bone or perforating the femoral shaft. The cement-in-cement
method avoids removal of intact cement and has shown good results
when used for revision total hip arthroplasty (THA). The use of
this technique for the revision of a hemiarthroplasty to THA has
not been previously reported. A total of 28 consecutive hemiarthroplasties (in 28 patients)
were revised to a THA using an Exeter stem and the cement-in-cement
technique. There were four men and 24 women; their mean age was
80 years (35 to 93). Clinical and radiographic data, as well as
operative notes, were collected prospectively and no patient was
lost to follow-up. Four patients died within two years of surgery. The mean follow
up of the remainder was 70 months (25 to 124). Intra-operatively
there was one proximal perforation, one crack of the
femoral calcar and one acetabular fracture. No femoral components
have required subsequent revision for aseptic loosening or are radiologically loose. Four patients with late complications (14%) have since undergone
surgery (two for a peri-prosthetic fracture, and one each for deep
infection and recurrent dislocation) resulting in an overall major
rate of complication of 35.7%. The cement-in-cement technique provides reliable femoral fixation
in this elderly population and may reduce operating time and rates
of complication. Cite this article:
