We have evaluated the survivorship, outcomes, and failures of an interlocking, reconstruction-mode stem-sideplate implant used to preserve the native hip joint and achieve proximal fixation when there is little residual femur during large endoprosthetic reconstruction of the distal femur. A total of 14 patients underwent primary or revision reconstruction of a large femoral defect with a short remaining proximal femur using an interlocking, reconstruction-mode stem-sideplate for fixation after oncological distal femoral and diaphyseal resections. The implant was attached to a standard endoprosthetic reconstruction system. The implant was attached to a standard endoprosthetic reconstruction system. None of the femoral revisions were amenable to standard cemented or uncemented stem fixation. Patient and disease characteristics, surgical history, final ambulatory statusAims
Methods
The purpose of this study was to assess whether
the use of a joint-sparing technique such as curettage and grafting was
successful in eradicating giant cell tumours of the proximal femur,
or whether an alternative strategy was more appropriate. Between 1974 and 2012, 24 patients with a giant cell tumour of
the proximal femur were treated primarily at our hospital. Treatment
was either joint sparing or joint replacing. Joint-sparing treatment
was undertaken in ten patients by curettage with or without adjunctive
bone graft. Joint replacement was by total hip replacement in nine patients
and endoprosthetic replacement in five. All 11 patients who presented
with a pathological fracture were treated by replacement. Local recurrence occurred in five patients (21%): two were treated
by hip replacement, three by curettage and none with an endoprosthesis.
Of the ten patients treated initially by curettage, six had a successful
outcome without local recurrence and required no further surgery.
Three eventually needed a hip replacement for local recurrence and
one an endoprosthetic replacement for mechanical failure. Thus 18
patients had the affected joint replaced and only six (25%) retained
their native joint. Overall, 60% of patients without a pathological
fracture who were treated with curettage had a successful outcome. Cite this article:
