A retrospective review of our prospectively collected database was undertaken and the functional and oncologic outcomes after Type One pelvic resections for bone tumours of the ilium and sacrum were analyzed. Seventeen patients were identified with a minimum followup after resection of twelve months. In seven patients the bone defect was reconstructed, with no reconstruction in the remaining ten patients. The functional/oncologic outcomes of the two groups are similar, however patients without reconstruction had fewer complications and less dependence on walking aids suggesting that reconstruction may not be justified.

Management of defects created by Type One pelvic resections of large iliac bone tumours remains controversial. We reviewed the functional/oncologic outcome following resection with and without reconstruction.

Similar functional/oncologic outcome was achieved in both groups suggesting that reconstruction is not justified.

A retrospective review of our prospectively collected database was undertaken analyzing functional/oncological outcome of seventeen patients with Type One pelvic resection. Minimum follow up was twelve months (12–96). Outcome data was available on 8/10 patients managed without reconstruction (WOR), with residual ilium collapsing back onto sacrum, and on 5/7 patients with bone graft reconstruction (WR).

Average age thirty-three years (WOR) and 48yrs (WR), (p=0.04), with average maximal tumour dimensions of 12cm and 9cm (p=0.1). The most frequent diagnosis was chondrosarcoma. The WOR group average TESS, MSTS 87 and MSTS 93 scores were respectively 73%, 18/35 and 58% at an average of 50 months (24–96) compared to 69%, 21/35 and 51% at an average of 37 months (12–60) for the WR group. 33% of WOR and 20% of WR patients did not require walking aids. Infection or wound necrosis occurred in 40% of WOR patients and 57% of WR patients. No local recurrences.

The perceived advantages of no reconstruction are shorter operating times, reduced incidence of complications and improved functional outcome due to medialization of the weightbearing axis in the absence of hip abductors. The oncologic/functional outcomes of both groups were similar but in those not reconstructed there was a lower incidence of complications and walking aids.

Patient postoperative outcome can be accurately predicted by the patient’s preoperative HHS or WOMAC score. Prospective, cohort studies of one hundred and seventy-five THAs. SF-36, WOMAC and Harris Hip Score (HHS)questionnaires were used to determine pre-operative and two year final outcome. Student’s t-test, 95% confidence intervals, receiver operator characteristic curves, simple regression analysis and probability were measured. Patients with a HHS = sixty-five pre-operatively had a 100% probability of having an excellent result postoperatively. A preoperative HHS value of thirty-four, and preoperative WOMAC (physical function) value of fifty were the best cutoff points to attain a significantly better postoperative functional outcome.

Total hip arthroplasty (THA) has been well documented to enhance patient function, but patient outcome is dependant on preoperative statuts. The exact timing of surgery to optimize patient outcome after THA remains unknown. This study determines the ideal timing for surgery to obtain the best possible functional outcome.

Prospective, multicenter, cohort studies of one hundred and seventy-five identical, cemented THAs. General health (SF-36) and disease specific (WOMAC and Harris Hip Score(HHS)) questionnaires were used to determine preoperative and two year final outcome. Student’s t-test, 95% confidence intervals, receiver operator characteristic curves, simple regression analysis and probabilty were measured.

All functional scores were improved significantly postoperatively (p< 0.001). Patients with a HHS = sixtyfive preoperatively had a 100% probability of having an excellent result postoperatively. A preoperative HHS value of thirty-four, and preoperative WOMAC (physical function) value of fifty were the best cutoff points to attain a significantly better postoperative functional outcome.

Patient postoperative outcome can be accurately predicted by the patient’s preoperative HHS or WOMAC score. Optimization of surgical timing, by prioritizing wait lists or deciding to treat the arthritis operatively, based on these preoperative score guidelines will help ensure an excellent outcome post THA.

Introduction and Aims: The management of bone defects created by Type 1 pelvic resections of large iliac bone tumors remains controversial. We reviewed the functional and oncologic outcome following Type I resection with and without bone reconstruction.

Method: A retrospective review of our prospectively collected database was undertaken analysing functional and oncological outcome of 16 patients with Type I pelvic resections. Minimum follow-up was 12 months (range 12–96 months). Outcome data was available on eight of 10 patients managed without reconstruction (WOR), with the residual ilium allowed to collapse back onto the sacrum, and on five of six patients with bone graft reconstruction (WR). Functional outcome was assessed by the Toronto Extremity Salvage score (TESS) and the Musculoskeletal Tumor Society scores (MSTS87 and MSTS93).

Results: Average age at surgery was 33 years (WOR) and 48 years (WR), (p=0.04), with average maximal tumor dimensions of 12cm and 9cm respectively (p=0.1). The most frequent diagnosis was chondrosarcoma. The WOR group average TESS, MSTS 87 and MSTS 93 scores were respectively 73%, 18/35 and 58% at an average of 50 months (range 24–96 months) compared to 69%, 21/35 and 51% at an average of 37 months (range 12–60 months) for the WR group. Thirty-three percent of WOR and 20% of WR patients did not require walking aids. Infection or wound necrosis occurred in 40% of WOR patients and 50% of WR patients. No local recurrences were identified.

Conclusion: Similar functional and oncologic outcome was achieved in both groups suggesting that bone reconstruction is not justified following Type I pelvic resection.
