Ilium is the most common site of pelvic Ewing’s sarcoma (ES). Resection of the ilium and iliosacral joint causes pelvic disruption. However, the outcomes of resection and reconstruction are not well described. In this study, we report patients’ outcomes after resection of the ilium and iliosacral ES and reconstruction with a tibial strut allograft. Medical files of 43 patients with ilium and iliosacral ES who underwent surgical resection and reconstruction with a tibial strut allograft between January 2010 and October 2021 were reviewed. The lesions were classified into four resection zones: I1, I2, I3, and I4, based on the extent of resection. Functional outcomes, oncological outcomes, and surgical complications for each resection zone were of interest. Functional outcomes were assessed using a Musculoskeletal Tumor Society (MSTS) score and Toronto Extremity Salvage Score (TESS).Aims
Methods
Few studies dealing with chondrosarcoma of the pelvis are currently
available. Different data about the overall survival and prognostic
factors have been published but without a detailed analysis of surgery-related complications.
We aimed to analyse the outcome of a series of pelvic chondrosarcomas
treated at a single institution, with particular attention to the
prognostic factors. Based on a competing risk model, our objective
was to identify risk factors for the development of complications. In a retrospective single-centre study, 58 chondrosarcomas (26
patients alive, 32 patients dead) of the pelvis were reviewed. The
mean follow-up was 13 years (one week to 23.1 years).Aims
Patients and Methods
The aims of this study were to evaluate the incidence
of local argyria in patients with silver-coated megaprostheses and
to identify a possible association between argyria and elevated
levels of silver both locally and in the blood. Between 2004 and
2011, 32 megaprostheses with silver coatings were implanted in 20
female and 12 male patients following revision arthroplasty for
infection or resection of a malignant tumour, and the levels of
silver locally in drains and seromas and in the blood were determined.
The mean age of the patients was 46 years (10 to 81); one patient
died in the immediate post-operative period and was excluded. Seven patients (23%) developed local argyria after a median of
25.7 months (interquartile range 2 to 44.5). Patients with and without
local argyria had comparable levels of silver in the blood and aspiration
fluids. The length of the implant did not influence the development
of local argyria. Patients with clinical evidence of local argyria
had no neurological symptoms and no evidence of renal or hepatic
failure. Thus, we conclude that the short-term surveillance of blood
silver levels in these patients is not required. Cite this article:
Pathological fractures due to metastasis with destruction of the acetabulum and central dislocation of the hip present a difficult surgical challenge. We describe a series using a single technique in which a stable and long-lasting reconstruction was obtained using standard primary hip replacement implants augmented by strong, fully-threaded steel rods with cement and steel mesh, where required. Between 1997 and 2006, 19 patients with a mean age of 66 years (48 to 83) were treated using a modified Harrington technique. Acetabular destruction was graded as Harrington class II in six cases and class III in 13. Reconstruction was achieved using three 6.5 mm rods inserted through a separate incision in the iliac crest followed by augmentation with cement and a conventional cemented Charnley or Exeter primary hip replacement. There were no peri-operative deaths. At the final follow-up (mean 25 months (5 to 110)) one rod had fractured and one construct required revision. Of the 18 patients who did not require revision, 13 had died. The mean time to death was 16 months (5 to 55). The mean follow-up of the five survivors was 31 months (18 to 47). There were no cases of dislocation, deep infection or injury to a nerve, the blood vessels or the bladder.
We treated 98 patients with peri-acetabular tumours by resection and reconstruction with a custom-made pelvic endoprosthesis. The overall survival of the patients was 67% at five years, 54% at ten years and 51% at 30 years. One or more complications occurred in 58.1% of patients (54), of which infection was the most common, affecting 30% (28 patients). The rate of local recurrence was 31% (29 patients) after a mean follow-up of 71 months (11 to 147). Dislocation occurred in 20% of patients (19). Before 1996 the rate was 40.5% (17 patients) but this was reduced to 3.9% (two patients) with the introduction of a larger femoral head. There were six cases of palsy of the femoral nerve with recovery in only two. Revision or excision arthroplasty was performed in 23.7% of patients (22), principally for uncontrolled infection or aseptic loosening. Higher rates of death, infection and revision occurred in men. This method of treatment is still associated with high morbidity. Patients should be carefully selected and informed of this pre-operatively.
