BACKGROUND:
The long-term results of total hip arthroplasty performed with cement and
use of a bulk autograft for acetabular reconstruction in patients with
developmental dysplasia of the hip have varied considerably. We evaluated the
results of total hip arthroplasties performed with acetabular bulk autograft
to identify the factors that influence the results of this procedure.
METHODS:
Acetabular roof defects secondary to developmental dysplasia of the hip
were reconstructed with a bulk femoral head autograft at the time of total hip
arthroplasties performed with use of the Charnley technique and prosthesis.
Thirty-seven hips in thirty patients (mean age at the time of the operation,
fifty-seven years) were followed for ten to twenty-six years (mean, nineteen
years). The Crowe classification of hip subluxation or dislocation was Group
II for sixteen hips, Group III for seventeen, and Group IV for four.
RESULTS:
Coverage of the socket by the graft ranged from 5% to 49% (mean, 33%).
Twenty-nine sockets were located within the true acetabulum, and eight were
placed more proximally. At the time of the latest follow-up, all of the
patients had an excellent clinical result, all of the grafts had united, and
no hip had radiographic evidence of failure of the fixation.
CONCLUSIONS:
We found that total hip arthroplasty performed with cement and use of a
bulk autograft to reconstruct an acetabulum with severe bone deficiency
secondary to developmental dysplasia of the hip can provide long-term success
in patients forty-eight years of age and older when coverage of the socket by
the graft does not exceed 50%. When it is not possible to achieve >50%
coverage of the socket by the ilium at the level of the true acetabulum, more
proximal placement of the socket to obtain adequate coverage is
recommended.
