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.

A retrospective review of our prospectively collected database was undertaken to determine the functional and oncologic outcome following combined pelvic allograft and total hip arthroplasty (THA) reconstruction of large pelvic bone defects following tumour resection. There were twenty-four patients with a minimum followup of fifteen months. The complication rate following hemipel-vic allograft and THA reconstruction of resection Types I+II and I+II+III was high, but when successful this reconstruction resulted in reasonable functional outcome. In comparison, the functional outcome after allograft and THA reconstruction of isolated Type II acetabular resections was better and more predictable.

Resection of large pelvic bone tumours often results in segmental defects with pelvic discontinuity and loss of the acetabulum. We reviewed the functional and oncologic outcomes following pelvic allograft and total hip arthroplasty (THA) reconstruction.

Reconstruction of large pelvic defects including the acetabulum using hemipelvic allograft and THA is associated with high complication rates, however when successful provides reasonable function. In comparison, the outcomes of allograft and THA for acetabular defects alone are better and more predictable.

A retrospective review of our prospectively collected database was undertaken. Minimum followup was fifteen months (15–167). Nineteen patients were hemipel-vic resections (twelve Type I+II and seven Type I+II+III, eleven cases including partial sacral resection) reconstructed by hemipelvic allograft and THA. Five patients had Type II acetabular resections, reconstructed with structural allograft, roof ring and THA.

Osteosarcoma and chondrosarcoma were the most frequent tumours. All patients required walking aids. In the hemipelvic group there were two early deaths (peri-operative haemorrhage and aplastic anaemia). In seven patients (37%) the allograft remained intact without infection but three required revision THA for loosening. For these seven patients the functional outcome scores were TESS 64%, MSTS87 17/35 and MSTS93 of 45% (mean fifty-two months.). There were nine cases of deep infection (47%) with three patients maintaining a functional implant. The nineteenth patient was revised following allograft fracture.

In the Type II acetabular group, three patients had no complications, and two patients dislocated. The average scores were TESS 78%, MSTS87 21/35 and MSTS93 64% (mean fifty-five months).

We retrospectively reviewed thirty-six patients who had undergone dorsal opening wedge osteotomies using cancellous bone graft and plate fixation for symptomatic healed angulated distal radius fractures.

Average improvement of the distal radius dorsal articular tilt was 28° and the ulna variance 2.7mm. The final average range of motion was flexion 46°, extension 62°, pronation 79°and supination 75°. The range of supination and pronation was not significantly different from the unaffected limb (p> 0.115).

For healed angulated distal radius fractures, dorsal opening wedge osteotomy combined with cancellous bone grafting and plate fixation, is a reliable technique allowing significant deformity correction.

We retrospectively reviewed thirty-six patients with symptomatic healed angulated distal radius fractures who had undergone dorsal opening wedge osteotomies using cancellous bone graft and plate fixation by a single surgeon. Twenty-five patients were reviewed both clinically and radiologically with an average follow-up of forty-seven months. The radiographs of a further eleven patients were reviewed.

Average age at surgery was fifty years with an interval from injury of twenty-nine months. All osteotomies united. 20% required plate removal.

Preoperatively the average distal radius articular tilt was 25° dorsal, and ulna variance +4.3mm. Following correction, average articular tilt was 3° volar, and ulna variance +2mm. These changes were highly significant (p< 0.0005). There was no significant loss of correction of the deformity between the immediate postoperative radiographs and those following union (p> 0.33).

The average range of motion was flexion 46°, extension 62°, pronation 79°and supination 75°. The range of pronation and supination was not significantly different from the unaffected limb (p> 0.115).

The average Patient Rated Wrist Evaluation Score was thirty, indicating residual pain and disability greater than that for an age matched cohort of patients with uncomplicated distal radius fractures (PRWE=15), previously reported by our laboratory. Patients reported that they were satisfied with the cosmetic appearance and had regained 73% of wrist use – these values had a significant negative correlation with the final ulna variance (p< 0.05).

For healed angulated distal radius fractures, dorsal opening wedge osteotomy combined with cancellous bone grafting and plate fixation, is a reliable technique allowing significant deformity correction.

Introduction and Aims: Resection of large pelvic bone tumors often results in segmental defects with pelvic discontinuity and loss of the acetabulum. We reviewed the functional and oncologic outcomes following pelvic allograft and total hip arthroplasty (THA) reconstruction.

Method: A retrospective review of our prospectively collected database was undertaken. Minimum follow-up was 15 months (range 15–167 months). Nineteen patients were hemipelvic resections (12 Type I+II and seven Type I+II+III, 11 of these cases included partial sacral resection) reconstructed by hemipelvic allograft and THA. In comparison, five patients had Type II acetabular resections, reconstructed with structural allograft, roof ring and THA. Functional outcome was assessed by the Toronto Extremity Salvage score (TESS) and the Musculoskeletal Tumor Society scores (MSTS87 and MSTS93).

Results: Osteosarcoma and chondrosarcoma were the most frequent tumors. All patients required walking aids. In the hemipelvic group there were two early deaths (peri-operative haemorrhage and aplastic anaemia). In seven patients (37%), the allograft remained intact without infection but three required revision THA for component loosening. For these seven patients, the functional outcome scores were TESS 64%, MSTS87 17/35 and MSTS93 45% (mean follow-up 52 months). There were nine cases of deep infection (47%) with three patients maintaining a functional implant with antibiotic suppression. Of the remaining six patients with infection, four patients required hindquarter amputation, one patient required allograft removal and the allograft fragmented in the remaining patient. The 19th patient was revised following allograft fracture. Five patients sustained at least one allograft fracture.

In the Type II acetabular group, three patients had no complications, and two patients sustained dislocations. The average scores were TESS 78%, MSTS87 21/35 and MSTS93 64% (mean follow-up 55 months).

Conclusion: Reconstruction of large pelvic defects including the acetabulum using hemipelvic allograft and THA is associated with high complication rates, however when successful provides reasonable function. In comparison, the functional outcome after allograft and THA reconstruction of isolated Type II acetabular resections was better and more predictable.

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.

Purpose: The ABG Total Hip Joint Replacement is a cementless, hydroxyapatite coated prosthesis designed to be metaphyseal loading. The aim of our study was to analyze the changes in proximal femoral bone mineral density (BMD) following implantation of this prosthesis.

Method: Dual energy x-ray absorptiometry (DEXA) scanning has been shown to be an accurate and reliable method of assessing BMD following total hip arthroplasty. 14 patients undergoing primary ABG Total Hip Joint Replacement were recruited into the study following informed consent. BMD was determined for each of the seven periprosthetic zones of Gruen from DEXA scans, which were performed serially at preoperative,, 3 months, 6 months, 1 year and 2 years.

Results: 8 patients have now completed their scans. The most dramatic change in BMD was found in zone 7 which is the femoral calcar. In this region there was a progressive decrease in average BMD to 75% of the preoperative value at 2 years. In zones 2 and 3 representing the femoral cortex lateral to the prosthesis there was an increase in BMD to approximately 114.5% at 3 months and this was maintained at 2 years. In the remaining zones BMD was reasonably stable between 97.5 and 101%.

Conclusion: We have found that in the 2 years following ABG hip arthroplasty there is a dramatic decrease in BMD to 75% within the region of the femoral calcar. Further scans are required to determine if this is progressive. In the remaining regions BMD is either increased or relatively well preserved.

Aim: To determine whether there is a difference in outcome between reamed and unreamed tibial nails.

Method: We performed a prospective, randomised trial comparing the results of reamed versus unreamed titanium tibial nails. Perioperative oxygen saturation and FIo2 were measured in each patient. Time to union was compared using survival analysis.

Results: There were 60 patients with 60 tibial shaft fractures including 10 (17%) compound fractures and three patients with thoracic trauma. There were 32 reamed and 28 unreamed nails. Fifty-seven nails were statically locked (95%). The average nail diameter in the reamed group was 9.7mm, significantly larger than that in the unreamed group (9.2mm), (p=0.02). There were no significant differences in average oxygen saturation and FIo2 between reamed and unreamed nails during insertion, immediately postoperatively or during the first two postoperative days. Forty-eight (80%) patients were followed until the fracture healed. Two patients died and 10 (17%) were lost to follow up. The mean time to union was 13.5 weeks in the reamed group versus 16 weeks in the unreamed group. This was not significant (p=0.2). There were 10 (17%) complications including one delayed union in each group, both united following ‘dynamization’. There were three compartment syndromes treated with fasciotomies. No nails broke and there were no deep infections.

Conclusion: We have shown no difference in the effects on pulmonary function between the two groups, but unfortunately we had insufficient patients to assess the effect of thoracic trauma.

Aim: In 1990 the Christchurch Hospital Sarcoma Clinic established management guidelines for patients with suspected sarcomas, recommending referral prior to investigation, biopsy and excision. The aim of this study was to determine whether these guidelines are being followed.

Method: A review of the case notes of all sarcomas referred to the Sarcoma Clinic between 1990 and 1999 was performed.

Results: There were 53 referrals, 34 (22%) from orthopaedic surgeons, 56 (37%) from general surgeons, 16 (10%) from general practice and 47 (31%) from other specialties. Only 83 (54%) of the referrals had followed the guidelines. Twenty-five (74%) of the orthopaedic referrals, 19 (34%) of the general surgical, 10 (63%) of the general practice and 29 (62%) of the other specialties had followed the guidelines. Seventy (46%) of the referrals had failed to follow the guidelines. Thirty-four (49%) of these had undergone excision inadequate for sarcoma prior to referral, of which eight had been re-excised. Twenty-four patients had not been staged prior to excision despite having a positive fine needle aspiration (FNA) in four cases. Eighteen patients (26%) had FNA or biopsy prior to imaging or referral.

Conclusion: Forty-six percent of sarcoma patients had not been treated according to the recommended guidelines. Forty-nine percent of these had inadequate primary sarcoma excision and this may have compromised their outcome. Orthopaedic surgeons had the best record for following the guidelines at 74% of referrals but this could be further improved. Doctors and especially surgeons need to be more aware of the principle of early referral of patients with suspected sarcomas.
