Abstract
INTRODUCTION Minimal trauma fractures (MTFs) often occur in older patients with osteoporosis and may be precipitated by falls risk-increasing drugs. One category of falls risk-increasing drugs of concern are those with sedative/anticholinergic properties. Collaborative medication management services such as Australia's Home Medicine Review (HMR) can reduce patients' intake of sedative/anticholinergics and improve continuity of care. This paper describes a protocol for an randomised controlled trial to determine the efficacy of an HMR service for patients who have sustained MTF. METHOD AND ANALYSIS Eligible participants are as follows: ≥65 years of age, using ≥5 medicines including at least one falls risk-increasing drug, who have sustained an MTF and under treatment in one of eight Osteoporosis Refracture Prevention clinics in Australia. Consenting participants will be randomised to control (standard care) or intervention groups. For the intervention group, medical specialists will refer to a pharmacist for HMR focused on reducing falls risk predominately through making recommendations to reduce falls risk medicines, and adherence to antiosteoporosis medicines. Twelve months from treatment allocation, comparisons between groups will be made. The main outcome measure is participants' cumulative exposure to sedative and anticholinergics, using the Drug Burden Index. Secondary outcomes include medication adherence, emergency department visits, hospitalisations, falls and mortality. Economic evaluation will compare the intervention strategy with standard care. ETHICS AND DISSEMINATION Approval was obtained via the New South Wales Research Ethics and Governance Information System (approval number: 2021/ETH12003) with site-specific approvals granted through Human Research Ethics Committees for each research site. Study outcomes will be published in peer-reviewed journals. It will provide robust insight into effectiveness of a pharmacist-based intervention on medicine-related falls risk for patients with osteoporosis. We anticipate that this study will take 2 years to fully accrue including follow-up. TRIAL REGISTRATION NUMBER ACTRN12622000261718.

Abstract
OBJECTIVE To examine patients' and carers' understanding of pharmacy generated medication labels. METHODS A user testing questionnaire was conducted individually for 80 participants at 2 hospitals through a face-to face semi-structured interview. Pharmacy generated medication labels from different locations were grouped based on components into 4 different variations. Participants were asked to read and demonstrate understanding of the dose and frequency from 1 of the 4 variations for 4 prescription medications. Twenty participants for each variation were recruited so that demographic characteristics matched between variations. RESULTS Overall, only 45% of participants were able to correctly understand the dose and frequency presented on all the pharmacy labels presented on medications. Medication labels with standardised timing performed better than other variations with 91% of participants able to determine the correct frequency. The use of numeric figures was understood by 80-90% of participants compared to the use of capitalised text (65-70%). Pharmacy generated medication labels that proposed one step were better understood than instructions that incorporated several steps. CONCLUSION/PRACTICE IMPLICATIONS The study supports the use of simple, clear and explicit written instructions along with the use of numeric figures in pharmacy generated medication labels to achieve higher understandability in patients.

Abstract
AIMS Extendible endoprostheses have been available for more than 30 years and have become more sophisticated with time. The latest generation is 'non-invasive' and can be lengthened with an external magnetic force. Early results have shown a worryingly high rate of complications such as infection. This study investigates the incidence of complications and the need for further surgery in a cohort of patients with a non-invasive growing endoprosthesis. PATIENTS AND METHODS Between 2003 and June 2014, 50 children (51 prostheses) had a non-invasive growing prosthesis implanted for a primary bone sarcoma. The minimum follow-up was 24 months for those who survived. Their mean age was 10.4 years (6 to 14). The incidence of complications and further surgery was documented. RESULTS The mean follow-up was 64 months (20 to 145). The overall survivorship of the patients was 84% at three years and 70% at five years. Revision-free survival was 81.7% at three years and 61.6% at five years with competing risk analysis. Deep infection occurred in 19.6% of implants at a mean of 12.5 months (0 to 55). Other complications were a failure of the lengthening mechanism in five prostheses (9.8%) and breakage of the implant in two (3.9%). Overall, there were 53 additional operations (0 to 5 per patient). A total of seven patients (14%) underwent amputation, three for local recurrence and four for infection. Their mean limb length discrepancy was 4.3 mm (0 to 25) and mean Musculoskeletal Tumor Society Score functional score was 26.5 (18 to 30) at the final follow-up. CONCLUSIONS When compared with previously published early results, this mid-term series has shown continued good functional outcomes and compensation for leg-length discrepancy. Infection is still the most common complication: post-operative wound healing problems, central line infection and proximal tibial location are the main risk factors.

Abstract
AIMS The aim of this study was to establish what happens to patients in the long term after endoprosthetic replacement for a primary malignant tumour of bone. PATIENTS AND METHODS We conducted a retrospective analysis of a prospectively maintained database to identify all patients who had undergone an endoprosthetic replacement more than 25 years ago and who were still alive. Their outcomes were investigated with reference to their complications and need for further surgery. A total of 230 patients were identified. Their mean age at diagnosis was 20.7 years (five to 62). The most common diagnosis was osteosarcoma (132). The most common site was the distal femur (102). RESULTS The mean follow-up was 29.4 years (25 to 43). A total of 610 further operations were undertaken, an average of 2.7 further operations per patient. A total of 42 patients (18%) still had the original prosthesis in place. The risk of amputation was 16% at 30 years (31 patients). Those without infection had a mean of 2.1 further operations (one to nine) while those with infection had a mean of 4.6 further operations (two to 11). The risk of infection persisted throughout the life of the prosthesis with a mean of 1% per year becoming infected. Of the 60 patients who developed an infection, 21 (35%) developed this following the primary procedure at a mean of 50 months, but another 19 developed this within a year of another surgical procedure. The risk of infection after any further surgery was 2.7%. The site with the highest risk of infection was the proximal tibia (43.3%). TAKE HOME MESSAGE This study highlights the inevitable need for further surgery following first-generation endoprosthetic reconstruction, although in most cases, limb salvage is maintained. Late complications, especially infection, continue for the lifetime of the implant. Cite this article: Bone Joint J 2016;98-B:857-64.

Abstract
We conducted a case-control study to examine the merit of silver-coated tumour prostheses. We reviewed 85 patients with Agluna-treated (silver-coated) tumour implants treated between 2006 and 2011 and matched them with 85 control patients treated between 2001 and 2011 with identical, but uncoated, tumour prostheses. In all, 106 men and 64 women with a mean age of 42.2 years (18.4 to 90.4) were included in the study. There were 50 primary reconstructions (29.4%); 79 one-stage revisions (46.5%) and 41 two-stage revisions for infection (24.1%). The overall post-operative infection rate of the silver-coated group was 11.8% compared with 22.4% for the control group (p = 0.033, chi-square test). A total of seven of the ten infected prostheses in the silver-coated group were treated successfully with debridement, antibiotics, and implant retention compared with only six of the 19 patients (31.6%) in the control group (p = 0.048, chi-square test). Three patients in the silver-coated group (3.5%) and 13 controls (15.3%) had chronic periprosthetic infection (p = 0.009, chi-square test). The overall success rates in controlling infection by two-stage revision in the silver-coated group was 85% (17/20) compared with 57.1% (12/21) in the control group (p = 0.05, chi-square test). The Agluna-treated endoprostheses were associated with a lower rate of early periprosthetic infection. These silver-treated implants were particularly useful in two-stage revisions for infection and in those patients with incidental positive cultures at the time of implantation of the prosthesis. Debridement with antibiotic treatment and retention of the implant appeared to be more successful with silver-coated implants.

Abstract
AIMS To investigate whether the oncological outcomes of patients with osteosarcomas in the upper distal extremity are similar to other sites and assess if limb-salvage surgery is safe in this location. METHODS The centre database was used to identify all patients with osteosarcomas in the lower humerus and distally between 1985 and 2012. Patient, tumor, treatment and outcome data was collected. RESULTS Twenty-six patients were included in this study. There were 9 males and 17 females with a mean age of 33 years (9-90). Seventeen osteosarcomas were located in the forearm bones (65%), six in the distal humerus (23%), and three (12%) in the hand. The three most common sub-diagnoses were parosteal 7/21 (33%), fibroblastic 4/21 (19%) and osteoblastic osteosarcomas 3/21 (14%). 2 patients (8%) had Paget's disease and 19 patients (73%) had high-grade tumors. Local excision was carried out in 12 patients (48%), 4 patients underwent endoprosthetic replacement (16%) and 9 underwent amputation (36%). The overall risk of local recurrence was 4% in our series. The five-year overall survival rate was 67%, with low tumor grade and parosteal type of osteosarcoma being positive predictors of survival. CONCLUSION This series has shown that patients with high-grade osteosarcomas of the upper distal extremities have a higher amputation risk than other limb sites but have favorable outcomes with limb-salvage surgery, comparable to other anatomical sites. Parosteal osteosarcomas in particular have a good prognosis.

Abstract
AIMS The aim of this study was to clarify the clinical features and outcomes of diaphyseal osteosarcoma. METHODS Patients with newly-diagnosed high-grade osteosarcoma occurring in the long bone were eligible for this retrospective study. Clinicopathological information was collected from our database and compared with 36 diaphyseal, 405 proximal and 519 distal metaphyseal, and 14 whole bone osteosarcoma patients. Additionally, case-control study matching by age, gender, site, and metastatic status at diagnosis with 1:3 ratio of 36 diaphyseal to 108 metaphyseal osteosarcomas patients was also conducted. RESULTS Five-year overall survival and metastasis-free survival of the three groups including diaphyseal, metaphyseal, and whole bone osteosarcoma patients showed significant difference (P = .029 and P = .013, respectively), although there is no difference for the survivals between proximal and distal metaphyseal osteosarcoma patients. Case-control study showed that patients with diaphyseal osteosarcomas had a significantly larger tumour (mean 13.5 cm vs 10 cm, P = .026), and demonstrated higher pathologic fracture rate (28% vs 12%, P = .033), superior 5-year metastasis-free survival (74% vs 40%, P = .0068), and slightly better 5-year overall survival (68% vs 46%, P = .074). Prognostic factor analysis showed that a pathologic fracture significantly decreased the survival of the patients with diaphyseal osteosarcoma. CONCLUSIONS The current study showed that diaphyseal osteosarcoma has distinct clinical features from metaphyseal osteosarcoma having an increased risk of pathologic fractures but with favorable survival outcome.

Abstract
We evaluated the risk of late relapse and further outcome in patients with soft-tissue sarcomas who were alive and event-free more than five years after initial treatment. From our database we identified 1912 patients with these pathologies treated between 1980 and 2006. Of these 1912 patients, 603 were alive and event-free more than five years after initial treatment and we retrospectively reviewed them. The mean age of this group was 48 years (4 to 94) and 340 were men. The mean follow-up was 106 months (60 to 336). Of the original cohort, 582 (97%) were alive at final follow-up. The disease-specific survival was 96.4% (95% confidence interval (CI) 94.4 to 98.3) at ten years and 92.9% (95% CI 89 to 96.8) at 15 years. The rate of late relapse was 6.3% (38 of 603). The ten- and 15-year event-free rates were 93.2% (95% CI 90.8 to 95.7) and 86.1% (95% CI 80.2 to 92.1), respectively. Multivariate analysis showed that tumour size and tumour grade remained independent predictors of events. In spite of further treatment, 19 of the 38 patients died of sarcoma. The three- and five-year survival rates after the late relapse were 56.2% (95% CI 39.5 to 73.3) and 43.2% (95% CI 24.7 to 61.7), respectively, with a median survival time of 46 months. Patients with soft-tissue sarcoma, especially if large, require long-term follow-up, especially as they have moderate potential to have their disease controlled.

Abstract
BACKGROUND Surgery remains the main treatment of bone metastases due to renal cell carcinoma (RCC). We reviewed 135 patients treated with resection and endoprosthetic replacement (EPR) and examined clinico-pathological factors predicting survival. METHODS Surgical and oncological outcomes were examined using a prospectively maintained database between 1976 and 2012. Survival rates were calculated by Kaplan-Meier method. Multivariate analyses were performed to investigate factors predictive of increased survival. RESULTS At diagnosis, 81 patients had synchronous RCC and bone metastases and the remaining developed metachronous metastases after primary treatment for RCC. The majority were solitary tumours (75%) and 77% had ≥ one concurrent visceral metastases. The median age at surgery was 61 years old (IQR 53-69). The median follow-up was 20 months (IQR 10-43) and the overall survival was 72% at one-year. This declined to 45% and 28% at three and five-years, respectively. After adjustments for prognostic factors, there was an increased risk of death in patients with multiple skeletal metastases (HR = 2), ≥one visceral metastases (HR = 3) and local recurrence (HR = 3) (all p ≤ 0.01). Ten patients required revision (7%) and the risk of revision was 4% at one-year and remained low at 8% from two years postoperatively. CONCLUSION Patients with solitary bone lesions and no visceral metastases should be considered for bone resection and EPR. As survival beyond one-year can be expected in a majority of patients and the risk of further surgery after EPR is low, patients with multiple skeletal metastases and visceral metastases should also be considered.

Abstract
A total of 157 hindquarter amputations were carried out in our institution during the last 30 years. We have investigated the reasons why this procedure is still required and the outcome. This operation was used as treatment for 13% of all pelvic bone sarcomas. It was curative in 140 and palliative in 17, usually to relieve pain. There were 90 primary procedures (57%) with the remaining 67 following the failure of previous operations to control the disease locally. The indication for amputation in primary disease was for large tumours for which limb-salvage surgery was no longer feasible. The peri-operative mortality was 1.3% (n = 2) and major complications of wound healing or infection arose in 71 (45%) patients. The survival at five years after hindquarter amputation with the intent to cure was 45%, and at ten years 38%. Local recurrence occurred in 23 patients (15%). Phantom pain was a significant problem, and only 20% used their prosthesis regularly. Functional scores were a mean of 57%. With careful patient selection the oncological results and functional outcomes of hindquarter amputation justify its continued use.

Abstract
We reviewed our initial seven-year experience with a non-invasive extendible prosthesis in 34 children with primary bone tumours. The distal femur was replaced in 25 cases, total femur in five, proximal femur in one and proximal tibia in three. The mean follow-up was 44 months (15 to 86) and 27 patients (79%) remain alive. The prostheses were lengthened by an electromagnetic induction mechanism in an outpatient setting and a mean extension of 32 mm (4 to 80) was achieved without anaesthesia. There were lengthening complications in two children: failed lengthening in one and the formation of scar tissue in the other. Deep infection developed in six patients (18%) and local recurrence in three. A total of 11 patients required further surgery to the leg. Amputation was necessary in five patients (20%) and a two-stage revision in another. There were no cases of loosening, but two patients had implant breakage and required revision. The mean Musculoskeletal Tumor Society functional score was 85% (60% to 100%) at last known follow-up. These early results demonstrate that the non-invasive extendible prosthesis allows successful lengthening without surgical intervention, but the high incidence of infection is a cause for concern.

Abstract
Seventeen patients underwent treatment for a pathological fracture of the proximal femur due to osteosarcoma. Their age range was from 9 to 84 (mean age 42) with nine patients under the age of 40 and eight above the age of 40. Twelve patients had a fracture at diagnosis and five developed a fracture after the diagnosis. Seven patients had metastatic disease at diagnosis. Five patients were referred after internal fixation of the fracture prior to diagnosis. Chemotherapy was used when appropriate and eight patients then underwent limb salvage surgery, six had an amputation, and three had palliative treatment. The estimated five-year survival was 14%. These results are significantly worse than expected, and it proved impossible to identify any group who fared well. The high incidence of metastases both at diagnosis and subsequently suggests this group of patients are at very high risk. Review of multicentre data may suggest an optimum treatment for this patient group.

Abstract
Purpose. The purpose of this study was to analyse the height at diagnosis and growth in 72 skeletally immature children who had been treated for osteosarcoma in the area of the knee. Subjects. Of the patients, the average age at diagnosis was 10 years in girls and 12 years in boys. All children received neo-adjuvant chemotherapy, and had limb salvage by endoprosthetic replacement. Results and conclusion. The results of this study indicate that there is no evidence that children with osteosarcoma are taller at diagnosis than their normal counterparts. However, there was a marked retardation in growth in the year following the administration of cytotoxic chemotherapy. There were 19 children who reached skeletal maturity. The final height in
these children was not significantly different from the normal population.

Abstract
Purpose Paget' s osteosarcoma has a fearful reputation with a quoted
survival of at best 5% at 5 years.We therefore reviewed our experience of 26 patients treated
over the last 25 years using modern staging and limb salvage techniques to see if there had
been any improvement in survival. Subjects: We identified 26 patients on the Royal Orthopaedic Hospital Oncological
database with a diagnosis of sarcoma secondary to Paget's disease. Results: The survival rate was 53% at 1 year, 25% at 2 years and no
patient survived for 5 years.The median survival was 21 months for those treated with
curative intent and 7 months for those treated palliatively. Four of the five patients treated
with limb-sparing surgery developed local recurrence between 5 and 12 months, the fifth
died at 14 months.There was no difference in survival between amputation and limb
salvage. Discussion: The development of sarcomatous change in Paget's
disease is well recognised. It represents an important segment of primary bone tumours in
patients over 40 years of age.The prognosis is appalling. Indeed only 15 of 368 cases (4%)
from a number of historical series have survived more than 5 years. Our results are similarly
disappointing with no survivors at 5 years despite modern methods of management of bone
tumours.While there is no difference in local recurrence rates or survival between limb
reconstruction and limb ablation the poor prognosis for both means that neither can be
recommended at present. Sarcomatous change in Pagetoid bone should therefore be
regarded as a different disease to primary osteosarcoma. It remains an incurable disease
with a poor prognosis.

Abstract
Purpose. The aim of this paper was to assess the growth in the unaffected lower limb of children who had received chemotherapy for a malignant primary bone tumour around the knee.Subjects/methods. Following diagnosis, all children (45, of which 32 were boys and 13 were girls) were staged. If limb-salvage surgery was thought appropriate, measured radiographs of both legs was performed, the bone age was estimated and the expected growth in the femur and tibia was calculated according to Tupman. These procedures were repeated at follow-up and the data plotted. Regression and correlation coefficients were also calculated.Results. The observed regression line in boys was almost identical to Tupman's curve. However, the observed growth in girls was larger than the expected growth.Discussion. It is recommended that the regression lines presented here are used in the calculation of the expected growth in the lower limb of children who have received chemotherapy for a malignant primary bone tumour, especially in girls.

Abstract
Purpose. We report on the quality of life following treatment for a malignant primary
bone tumour around the knee in skeletally immature children. Patients. Patients (n = 41; mean age = 18 years; range 8–28) had all
experienced chemotherapy in a neo-adjuvant setting, surgical excision of the tumour and endoprosthetic replacement. Methods. Interviews were conducted separately with the child and mother and focused
on mobility, body image and the impact of treatment on schooling, employment and plans for the future. Results. Mobility in the group was variable. Only 12% reported that they could run with
any confidence. The proportion who were able to swim (49%) or ride a bike (46%) was higher.
All had experienced major disruption in schooling (mean absence following diagnosis = 12 months).
Eight had repeated a school year and 41% patients reported that their schoolwork was affected.
As a result of their experience, eight (six females and two males) chose health-related employment.
Concerns for the future were highest among males and those with manual jobs. Three patients were receiving
psychiatric support, in relation to extreme concern about the risk of recurrence. All expressed satisfaction with treatment,
and older patients believed that the prosthesis gave a better quality of life than amputation. Discussion. Our data suggest that outcome following limb-salvage surgery is variable. Education is disrupted. Even so, only two left school with no qualifications. Employment is most restricted among males with few qualifications who may benefit from sensitive vocational counselling.

Abstract
Purpose Limb salvage surgery of soft tissue sarcomas is associated with both a risk of local recurrence and wound complications.
Although the lower limb appears to be at greater risk of wound-related morbidity, few studies separate anatomical
compartments. We believe that the adductor compartment of the thigh has a particularly high rate of complications and so
performed a retrospective analysis of all soft tissue sarcomas arising in this region undergoing limb salvage. Patients Patients with intermediate and high grade adductor compartment tumours were identified from our database and
the case notes were reviewed for patient, tumour, surgical and wound variables, identifying those with wound complications
both before and after discharge. Results Of 49 patients who underwent limb salvage surgery, 22 (42.9%) developed complications. Twelve patients (24.5%)
required further surgery prior to wound healing and 10 patients had delays in post-operative radiotherapy. There were significant
differences in the rates of preceding surgery, open biopsy performed at other centres and previous radiotherapy to this
region between the complicated and uncomplicated groups. Discussion The management of these difficult tumours carries a high rate of wound complications and requires careful planning
prior to tissue biopsy. Open biopsies should be performed by the tumour surgeon to allow easy inclusion of this site in
the definitive procedure. In previously irradiated or operated limbs, alternative strategies for wound management may need
to be considered.

Abstract
Purpose. Clear cell chondrosarcoma is a rare variant of chondrosarcoma. Six cases
are herein reported. Subjects. We have treated six patients with clear cell chondrosarcoma in the past 28
years, representing 1.6% of all chondrosarcomas seen in this time period. Results and Discussion. Half the patients had been initially underdiagnosed and
inappropriately treated. Conclusions. Our results and our review of the literature highlight the fact that
inadequate initial treatment leads to a high rate of both local recurrence and
metastasis whilst wide initial excision is usually curative.

Abstract
The aim of this study was to identify whether there was any difference in patient, tumour, treatment or outcome characteristics between patients with skeletal or extra-skeletal Ewing's sarcoma. We identified 300 patients with new primary Ewing's sarcoma diagnosed between 1980 and 2005 from the centres' local database. There were 253 (84%) with skeletal and 47 (16%) with extra-skeletal Ewing's sarcomas. Although patients with skeletal Ewing's were younger (mean age 16.8 years) than those with extra-skeletal Ewing's sarcoma (mean age 27.5 years), there was little difference between the groups in terms of tumour stage or treatment. Nearly all the patients were treated with chemotherapy and most had surgery. There was no difference in the overall survival of patients with skeletal (64%) and extra-skeletal Ewing's sarcoma (61%) (p = 0.85), and this was also the case when both groups were split by whether they had metastases or not. This large series has shown that the oncological outcomes of Ewing's sarcoma are related to tumour characteristics and patient age, and not determined by whether they arise in bone or soft tissue.

Abstract
We present our experience of treating patients with tumours involving the whole femur with excision and total femur endoprostheses over the last 30 years (1975-2005). There were 26 consecutive patients (14 men and 12 women). Average age was 40 years (14-82 years) at the time of surgery and 21 of the patients had primary malignant bone tumours with five having the procedure for metastases. 11 patients were still alive of which nine were free of disease at the time of review at a mean follow-up of 57 months (3-348). The overall patient survival at 10 years was 37%. The survival of patients with a primary localised tumour was 50% at 10 years. Revision of the prostheses was necessary in two patients (at 110 and 274 months) because of recurrent dislocation and aseptic loosening. Amputation was necessary in two patients but long term limb survival was 92% at 10 years. Nine patients alive with no evidence of disease had a mean MSTS functional score of 72%.

Abstract
AIM Research involving coronary artery disease (CAD) risk in young adults is limited; therefore we compared cardiovascular risk between college-aged men and women. METHODS Thirty college men and women volunteered as study subjects. CAD risk assessment included systolic blood pressure (SBP), diastolic blood pressure (DBP), waist circumference, percent body fat (%BF), maximum oxygen consumption, fasting plasma C-reactive protein (CRP), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), Body Mass Index (BMI) and fasting glucose. Risk factors were compared between groups using a t-test and Pearson product moment correlations were used to determine the relationships between CRP and CAD risk factors. RESULTS Statistically significant differences were observed for HDL, TC/HDL ratio, SBP, and %BF, between men and women. Total cholesterol and CRP concentration were not different between men and women. Log CRP was positively correlated with %BF and BMI. Further, 47% of the subjects met the criteria for one or more risk factors for CAD, as specified by the American College of Sports Medicine. CONCLUSION Our data indicate a gender difference in CAD risk in college students with similar reported activity. Waist circumference, fasting glucose, % body fat, and BMI are associated with CRP in college age men and women.

Abstract
To investigate the outcome of our management of patients with giant cell tumour of the sacrum and draw lessons from this. A retrospective review of medical records and scans for all patients treated at our unit over the past 20 years with a giant cell tumour of the sacrum. Of the 517 patients treated at our unit for giant cell tumour over the past 20 years, only 9 (1.7%) had a giant cell tumour in the sacrum. Six were female, three male with a mean age of 34 (range 15-52). All, but two tumours involved the entire sacrum and there was only one purely distal to S3. The mean size was 10 cm and the most common symptom was back or buttock pain. Five had abnormal neurology at diagnosis, but only one presented with cauda equina syndrome. The first four patients were treated by curettage alone, but two patients had intraoperative cardiac arrests and although both survived all subsequent curettages were preceded by embolisation of the feeding vessels. Of the seven patients who had curettage, three developed local recurrence, but all were controlled with a combination of further embolisation, surgery or radiotherapy. One patient elected for treatment with radiotherapy and another had excision of the tumour distal to S3. All the patients are alive and only two patients have worse neurology than at presentation, one being impotent and one with stress incontinence. Three patients required spinopelvic fusion for sacral collapse. All patients are mobile and active at a follow-up between 2 and 21 years. Giant cell tumour of the sacrum can be controlled with conservative surgery rather than subtotal sacrectomy. The excision of small distal tumours is the preferred option, but for larger and more extensive tumours conservative management may well avoid morbidity whilst still controlling the tumour. Embolisation and curettage are the preferred first option with radiotherapy as a possible adjunct. Spinopelvic fusion may be needed when the sacrum collapses.

Abstract
BACKGROUND Curettage of benign tumours commonly results in significant bone defects that are reconstructed with autologous grafts, allografts, bone cement or bone substitute. We have treated such defects in the talus without reconstruction with bone or any other material. We now report the healing of these ungrafted defects in eight patients treated with curettage for benign talar tumours. METHODS Eight consecutive patients were reviewed retrospectively at a mean follow-up of 82 months (range: 28-180 months). Mean age was 21.7 years (range: 12.3-31.3 years) and mean defect size was 16.5 cm(3) (range: 3.5-48 cm(3)). Outcome measures included time to radiological consolidation, ankle pain and stiffness, talar collapse, and tibiotalar joint osteoarthritis. RESULTS Full consolidation of the defect occurred within 6-12 months in all patients. One patient had minor discomfort over the scar, but there was no ankle joint pain. Two patients had some ankle stiffness, although one had established ankle osteoarthritis prior to surgery. No talar collapse, fracture or new significant osteoarthritis of the ankle was observed. CONCLUSIONS We conclude that bone grafting is not a necessary adjunct to the curettage of talar lesions.

Abstract
Endoprosthetic replacement of the proximal femur may be required to treat primary bone tumours or destructive metastases either with impending or established pathological fracture. Modular prostheses are available off the shelf and can be adapted to most reconstructive situations for this purpose. We have assessed the clinical and functional outcome of using the METS (Stanmore Implants Worldwide) modular tumour prosthesis to reconstruct the proximal femur in 100 consecutive patients between 2001 and 2006. We compared the results with the published series for patients managed with modular and custom-made endoprosthetic replacements for the same conditions. There were 52 males and 48 females with a mean age of 56.3 years (16 to 84) and a mean follow-up of 24.6 months (0 to 60). In 65 patients the procedure was undertaken for metastases, in 25 for a primary bone tumour, and in ten for other malignant conditions. A total of 46 patients presented with a pathological fracture, and 19 presented with failed fixation of a previous pathological fracture. The overall patient survival was 63.6% at one year and 23.1% at five years, and was significantly better for patients with a primary bone tumour than for those with metastatic tumour (82.3% vs 53.3%, respectively at one year (p = 0.003)). There were six early dislocations of which five could be treated by closed reduction. No patient needed revision surgery for dislocation. Revision surgery was required by six (6%) patients, five for pain caused by acetabular wear and one for tumour progression. Amputation was needed in four patients for local recurrence or infection. The estimated five-year implant survival with revision as the endpoint was 90.7%. The mean Toronto Extremity Salvage score was 61% (51% to 95%). The implant survival and complications resulting from the use of the modular system were comparable to the published series of both custom-made and other modular proximal femoral implants. We conclude that at intermediate follow-up the modular tumour prosthesis for proximal femur replacement provides versatility, a low incidence of implant-related complications and acceptable function for patients with metastatic tumours, pathological fractures and failed fixation of the proximal femur. It also functions as well as a custom-made endoprosthetic replacement.

Abstract
We report our experience of treating 17 patients with benign lesions of the proximal femur with non-vascularised, autologous fibular strut grafts, without osteosynthesis. The mean age of the patients at presentation was 16.5 years (5 to 33) and they were followed up for a mean of 2.9 years (0.4 to 19.5). Histological diagnoses included simple bone cyst, fibrous dysplasia, aneurysmal bone cysts and giant cell tumour. Local recurrence occurred in two patients (11.7%) and superficial wound infection, chronic hip pain and deep venous thrombosis occurred in three. Pathological fracture did not occur in any patient following the procedure. We conclude that non-vascularised fibular strut grafts are a safe and satisfactory method of treating benign lesions of the proximal femur.

Abstract
We investigated whether our policy of routine re-excision of the tumour bed after an unplanned excision of a soft-tissue sarcoma was justified. Between April 1982 and December 2005, 2201 patients were referred to our hospital with the diagnosis of soft-tissue sarcoma, of whom 402 (18%) had undergone an unplanned excision elsewhere. A total of 363 (16.5%) were included in this study. Each patient was routinely restaged and the original histology was reviewed. Re-excision was undertaken in 316 (87%). We analysed the patient, tumour and treatment factors in relation to local control, metastasis and overall survival. Residual tumour was found in 188 patients (59%). There was thus no residual disease in 128 patients of whom 10% (13) went on to develop a local recurrence. In 149 patients (47%), the re-excision specimen contained residual tumour, but it had been widely excised. Local recurrence occurred in 30 of these patients (20%). In 39 patients (12%), residual tumour was present in a marginal resection specimen. Of these, 46% (18) developed a local recurrence. A final positive margin in a high-grade tumour had a 60% risk of local recurrence even with post-operative radiotherapy. Metastases developed in 24% (86). The overall survival was 77% at five years. Survival was related to the grade of the tumour and the finding of residual tumour at the time of re-excision. We concluded that our policy of routine re-excision after unplanned excision of soft-tissue sarcoma was justified in view of the high risk of finding residual tumour.

Abstract
BACKGROUND Excision of a bone tumor requires reconstruction if limb salvage is a priority. Reconstruction with an endoprosthetic implant is preferred in our unit, as the patient typically can return rapidly to full weight-bearing and functional activities. Long-term complications, such as deep infection, aseptic loosening, and mechanical failure of the implants, have led to concerns about the efficacy of reconstruction and the ability to revise failed implants while maintaining limb salvage in the longer term. The purpose of this study was to investigate the survival of endoprosthetic reconstructions in the medium to long term in order to determine the factors associated with their failure. METHODS A consecutive series of 776 patients underwent endoprosthetic reconstruction following resection of a bone tumor at a minimum of ten years prior to this investigation. One hundred and nine children with a so-called growing endoprosthesis were excluded as they often require revision to an adult prosthesis near skeletal maturity. Six patients were excluded because of a lack of adequate follow-up data, leaving 661 patients for analysis. Kaplan-Meier survival analysis of the implant was performed, with implant revision for any cause (infection, local recurrence, and mechanical failure), mechanical failure alone, and amputation used as the end points. RESULTS The mean duration of follow-up was fifteen years for patients who survived the original disease. Two hundred and twenty-seven patients (34%) had revision surgery because of mechanical failure (116 patients), infection (seventy-five patients), and locally recurrent disease (thirty-six patients). Implant survival at ten years was 75% with mechanical failure as the end point and 58% with failure from any cause as the end point. The limb salvage rate was 84% at twenty years. CONCLUSIONS We believe these medium to long-term results with first-generation endoprostheses are encouraging and justify the continued use of endoprostheses for reconstruction following the excision of a bone tumor.

Abstract
We have investigated whether improvements in design have altered the outcome for patients undergoing endoprosthetic replacement of the proximal tibia following resection of a tumour. Survival of the implant and 'servicing' procedures have been documented using a prospective database. A total of 194 patients underwent a proximal tibial replacement, with 95 having a fixed-hinge design and 99 a rotating-hinge with a hydroxyapatite collar; their median age was 21.5 years (10 to 74). At a mean follow-up of 14.7 years (5 to 29), 115 patients remain alive. The risk of revision for any reason in the fixed-hinge group was 32% at five years, 61% at ten years and 75% at 15 and 20 years, and in the rotating-hinge group 12% at five years, 25% at ten years and 30% at 15 years. Aseptic loosening was the most common reason for revision in the fixed-hinge knees, fracture of the implant in the early design of rotating hinges and infection in the current version. The risk of revision for aseptic loosening in the fixed-hinge knees was 46% at ten years. This was reduced to 3% in the rotating-hinge knee with a hydroxyapatite collar. The cemented, rotating hinge design currently offers the best chance of long-term survival of the prosthesis.

Abstract
We investigated whether improvements in design have altered the outcome for patients undergoing endoprosthetic replacement of the distal femur after resection of a tumour. Survival of the implant and 'servicing' procedures have been documented using a prospective database, review of the design of the implant and case records. In total, 335 patients underwent a distal femoral replacement, 162 having a fixed-hinge design and 173 a rotating-hinge. The median age of the patients was 24 years (interquartile range 17 to 48). A total of 192 patients remained alive with a mean follow-up of 12 years (5 to 30). The risk of revision for any reason was 17% at five years, 33% at ten years and 58% at 20 years. Aseptic loosening was the main reason for revision of the fixed-hinge knees while infection and fracture of the stem were the most common for the rotating-hinge implant. The risk of revision for aseptic loosening was 35% at ten years with the fixed-hinge knee, which has, however, been replaced by the rotating-hinge knee with a hydroxyapatite collar. The overall risk of revision for any reason fell by 52% when the rotating-hinge implant was used. Improvements in the design of distal femoral endoprostheses have significantly decreased the need for revision operations, but infection remains a serious problem. We believe that a cemented, rotating-hinge prosthesis with a hydroxyapatite collar offers the best chance of long-term survival of the prosthesis.

Abstract
We identified 42 patients who presented to our unit over a 27-year period with a secondary radiation-induced sarcoma of bone. We reviewed patient, tumour and treatment factors to identify those that affected outcome. The mean age of the patients at presentation was 45.6 years (10 to 84) and the mean latent interval between radiotherapy and diagnosis of the sarcoma was 17 years (4 to 50). The median dose of radiotherapy given was estimated at 50 Gy (mean 49; 20 to 66). There was no correlation between radiation dose and the time to development of a sarcoma. The pelvis was the most commonly affected site (14 patients (33%)). Breast cancer was the most common primary tumour (eight patients; 19%). Metastases were present at diagnosis of the sarcoma in nine patients (21.4%). Osteosarcoma was the most common diagnosis and occurred in 30 cases (71.4%). Treatment was by surgery and chemotherapy when indicated: 30 patients (71.4%) were treated with the intention to cure. The survival rate was 41% at five years for those treated with the intention to cure but in those treated palliatively the mean survival was only 8.8 months (2 to 22), and all had died by two years. The only factor found to be significant for survival was the ability to completely resect the tumour. Limb sarcomas had a better prognosis (66% survival at five years) than central ones (12% survival at five years) (p = 0.009). Radiation-induced sarcoma is a rare complication of radiotherapy. Both surgical and oncological treatment is likely to be compromised by the treatment received previously by the patient.

Abstract
The influence of pathological fracture on surgical management, local recurrence and survival was established in patients with high grade, localised, extremity osteosarcoma (n=484), chondrosarcoma (n=130) and Ewing's sarcoma (n=156). Limb salvage was possible in 79% of patients with a fracture compared to 84% of patients without a fracture (p=0.17). No difference in local recurrence was found between fracture and control groups. In univariate analysis, survival in the fracture group was lower than in the control group for osteosarcoma (34% versus 58%, p<0.01) and chondrosarcoma (35% versus 63%, p=0.04), but not for Ewing's sarcoma (75% versus 64%, p=0.80). In multivariate analysis, fracture remained a significant predictor of survival for osteosarcoma, but not for chondrosarcoma, where dedifferentiated subtype appeared to be decisive. Pathological fracture independently predicts worse survival in osteosarcoma, but not chondrosarcoma and Ewing's sarcoma. Limb saving surgery seems safe, if adequate resection margins are achieved.

Abstract
BACKGROUND Despite neo-adjuvant chemotherapy osteosarcomas having significant mortality, recent studies have shown survival advantages following infections for some tumour types. This study investigates the effect of post-operative infection in patients treated for osteosarcoma using endoprosthetic replacement and neo-adjuvant chemotherapy. MATERIAL AND METHODS A consecutive series of 547 patients underwent surgery between 1981 and 2001 for osteosarcoma. Patients were excluded from the study if over 60 years old at diagnosis (n = 14) as they would not routinely receive chemotherapy. Studies showed that 70% of deep infections occur within one year from reconstruction. Therefore landmark analysis was performed; all patients infected after 12 months of reconstruction were excluded (15 patients, 2.7%) and those who died within 12 months from diagnosis due to metastases were excluded (105 patients, 19.2%), leaving 412 patients. Any survival advantage of early infection was analysed by Kaplan-Meier survival analysis from this landmark point. RESULTS Overall population survival was 65% at 10 years after landmarking. There were 41 patients (10%) who developed an infection within one year of implantation. These patients had significantly better survival (p = 0.017). The 10-year survival for patients with osteosarcoma with infection was 84.5% compared to 62.3% in the non-infected group after landmarking. There was no significant difference in the percentage post-chemotherapy specimen necrosis between the two groups (p = 0.36). Infection was an independent prognostic factor on cox regression analysis. CONCLUSIONS There was evidence for increased survival after deep post-operative infection in osteosarcoma patients, in keeping with other research. The authors feel this warrants further investigation.

Abstract
UNLABELLED Malignant triton tumour (MTT) is a very rare soft tissue tumour. AIM To report nine patients diagnosed with malignant triton tumour of the thigh between January 1996 and January 2005 to determine the natural history and factors that may affect survival in this aggressive tumour. METHODS Due to the association of Neurofibromatosis (NF Type I) with malignant triton tumour, two groups of patients were identified: those with NF type I (Group I cases); and those without (Group II). RESULTS Group I patients accounted for four cases and arose predominantly in young males, all tumours being high grade, >10 cm in size and all four patients died within two years of diagnosis. By contrast, the five patients of Group II were older, had smaller size and lower grade tumours and three patients are long-term survivors. CONCLUSION Although the number of cases is small, our data supports the views that the natural history of MTT is more aggressive in patients with NF type I. This poor outlook could be attributed to the high frequency of Grade III histology in this disease and the large tumour size.

Abstract
Giant cell tumours are rare bone tumours that are characteristically benign but locally aggressive, most frequently occurring in the distal femur with pathological fractures being common. This paper investigates relationships between tumour size and cortical breach on initial X-rays and subsequent treatment. The X-rays of 54 patients with distal femoral giant cell tumours were reviewed. The volumes of the tumour, distal femur and a ratio between the two parameters were estimated. The presence of a cortical breach, discrete fracture and Campanacci grade was recorded. X-rays revealed intact cortical rim in 20 patients (37%), cortical breach in 22 patients (41%) and discrete fracture in 12 patients (22%). There was a significant difference in the ratio of tumour volume to distal femoral volume between the discrete fracture group and the cortical breach group. No significant differences in rates of local recurrence were demonstrated. Extended curettage was effective for intact and cortical breach groups; however, patients in the fracture group often required radical treatment.

Abstract
AIMS To review the oncological and functional outcome in 80 patients who underwent disarticulation of the hip as part of their treatment. METHODS Eighty patients had disarticulation, of whom 46 had a bone sarcoma and 34 a soft tissue sarcoma. In 42 patients the operation was done as the first definitive surgical procedure for that patient. In 38 patients the disarticulation followed local recurrence after unsuccessful limb salvage, three of these patients had palliative amputations already having metastatic disease. All patients had adjuvant therapy when appropriate. RESULTS The overall survival of the patients following the amputation was 56% at 1 year, 39% at 2 years, 27% at 5 years and 21% at 10 years. The 5-year survival of patients having the amputation as a primary procedure was 32%, for those with local recurrence it was 25% whilst for those with a palliative amputation it was nil. Local recurrence developed in 10 patients following the amputation, and was related to close margins of excision; all of these patients subsequently died. Function was on the whole poor, with only one surviving patient regularly using an artificial limb. CONCLUSION Disarticulation of the hip remains a disabling procedure usually carried out for high grade sarcomas with extensive involvement of bone and soft tissues in the thigh. Long term survival is possible if wide margins of excision can be achieved.

Abstract
We undertook this retrospective study to determine the rate of recurrence and functional outcome after intralesional curettage for chondroblastoma of bone. The factors associated with aggressive behaviour of the tumour were also analysed. We reviewed 53 patients with histologically-proven chondroblastoma who were treated by intralesional curettage in our unit between 1974 and 2000. They were followed up for at least two years to a maximum of 27 years. Seven (13.2%) had a histologically-proven local recurrence. Three underwent a second intralesional curettage and had no further recurrence. Two had endoprosthetic replacement of the proximal humerus and two underwent below-knee amputation after aggressive local recurrence. One patient had the rare malignant metastatic chondroblastoma and eventually died. The mean Musculoskeletal Tumour Society functional score of the survivors was 94.2%. We conclude that meticulous intralesional curettage alone can achieve low rates of local recurrence and excellent long-term function.

Abstract
UNLABELLED Adjuvant treatment or filling agents have been recommended for reducing recurrence rates of giant-cell tumors of bone. However, reports of low recurrence rates without either caused us to question this concept. We retrospectively reviewed 193 patients treated during a 27-year period, comparing our results with historic controls. One hundred thirty-seven patients had curettage as a primary treatment, and of these, 26 (19%) had local recurrences. The local recurrence rate of giant-cell tumors confined to bone (Campanacci Grades I and II) was only 7% compared with 29% in tumors with extraosseous extension (Campanacci Grade III). Six patients (4%) had a fracture after curettage. Twenty-nine patients who were referred to us with local recurrences after treatment elsewhere had curettage, and 10 (34%) of these patients had local recurrences develop. Twenty-seven patients had excision as their primary treatment, and two (7%) of these patients had local recurrence develop. We recommend primary curettage for intraosseous giant-cell tumors without adjuvant treatment or filling agents, but tumors with soft tissue extension or with local recurrence require more aggressive treatment. LEVEL OF EVIDENCE Therapeutic study, Level IV (case series--no, or historical control group). See the Guidelines for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND Prosthetic replacement following excision of a bone tumor can be complicated by infection because patients who undergo surgery for a neoplastic condition often are subjected to extensive soft-tissue dissection and long operating times and are immunosuppressed. The aim of this study was to investigate the rate of periprosthetic infection, identify possible predisposing factors, and assess treatment efficacy in such patients. METHODS Prosthetic reconstruction was performed in 1264 patients over a thirty-seven-year period in a single hospital by four surgeons. Twenty-four patients were excluded because of incomplete follow-up, leaving 1240 patients who had been followed for a mean of 5.8 years. Infection was identified in 136 patients (11.0%). The management and outcome of the infections in all of these patients were analyzed. RESULTS Coagulase-negative Staphylococcus was the most common organism isolated. Two-stage revision successfully treated the infection in 72% (forty-two) of the fifty-eight patients in whom it was performed. Local surgical debridement with or without antibiotic implants was successful in only 6% (four) of sixty-eight patients. Amputation to treat the infection was performed in fifty (37%) of the 136 patients. The factors that were associated with a significant risk of infection (p <or= 0.05) included tibial and pelvic prosthetic replacements, radiation therapy, and the use of a pediatric expandable prosthesis. CONCLUSIONS Patients treated with an orthopaedic procedure for an oncological condition have high infection rates. The treatment of infection in these patients is arduous and lengthy, with a substantial risk of amputation.

Abstract
We retrospectively studied 35 patients who underwent endoprosthetic reconstruction of diaphyseal bone defects after excision of primary sarcomas. The patients were treated between February 1979 and May 1999 and had more than 5 years follow-up. There were 22 males and 13 females and the median age at diagnosis was 29 (8-75) years. The bone defect measured a mean of 19 (10-27.6) cm. There were 29 femoral reconstructions, three tibial and three humeral. Cumulative overall survival for all patients was 65% at 10 years. Cumulative overall survival for prosthetic reconstruction, using revision surgery as an end point, was 63% at 10 years. Cumulative risk of failure of reconstruction, including infection, fracture, aseptic loosening, local recurrence and amputation, was 60% at 10 years. Tibial and humeral reconstructions fared less well than femoral. Endoprosthetic replacement is a useful method of reconstructing long intercalary defects, especially if situated in the femur.

Abstract
Core-shell molecularly imprinted particles (CS-MIPs) have been synthesised using the technique of emulsion polymerisation with caffeine and theophylline being used in the surface template polymerisation with ethylene glycol dimethacrylate and oleylphenyl hydrogen phosphate. A radiolabelling study with caffeine-8-14C showed that the template was completely located at the particle surface during polymerisation. Caffeine could be specifically bound to a caffeine-imprinted CS-MIP to give a biphasic Scatchard binding curve, whereas the binding profile to a theophylline-imprinted CS-MIP was monophasic. The nanoparticles have the potential to be used in the molecular recognition of small molecules in a complex biological matrix. Water soluble highly-branched imidazole end-chain functionalised polymers of nanodimensions have also been synthesised via reversible addition-fragmentation chain transfer polymerisation. The polymers have lower critical solution temperatures which occur at sub-ambient temperatures and have proven useful in the affinity precipitation of proteins which are particularly temperature sensitive, e.g. the histidine-tagged protein fragment BRCA1. An overview of both of these areas of research is described outlining the diversity of these aqueous compatible polymers in molecular recognition processes at the nanoscale.

Abstract
BACKGROUND Giant-cell tumour of the distal radius is a rare neoplasm that affects the peri-articular metaphysial region of the bone. Curettage alone or with bone grafting has been reported to be associated with high incidence of local recurrence in these tumours. In the present series, we report the results of curettage only as the treatment for primary giant-cell tumour of the distal radius carried out at a single centre. PATIENTS AND RESULTS A total of 287 patients with giant-cell tumour have been referred to us for treatment over the last 28 years; 24 of these were found to have lesion in the distal radius. One patient underwent endoprosthetic replacement of the distal radius. The remaining 23 patients underwent curettage of the primary neoplasm. Four out of the 23 (17%) patients developed local recurrence of disease, The mean time to local recurrence was 17 months (range, 9-27 months). Complications such as collapse of the articular cartilage are more common in patients with an extensive soft tissue component of the tumour. CONCLUSIONS Curettage alone is adequate treatment for the majority of patients with giant-cell tumours of the distal radius but some form of stabilisation may be required in the presence of extensive bone destruction.

Abstract
We studied 100 patients who had undergone endoprosthetic replacement of the proximal humerus between 1976 and 1998. The outcome was assessed with regard to the survivorship of the patients, the salvaged limbs and the prostheses. Function was determined in the 47 surviving patients, of whom 30 were assessed using the Musculo-Skeletal Tumour Society (MSTS) rating scale and 38 completed the Toronto Extremity Salvage Score (TESS) questionnaire. The median age of the patients was 34 years (10 to 80). The mean follow-up period for surviving patients was nine years (2 to 20). The mean MSTS score at follow-up was 79% and the mean TESS score was 72%. The length of bone which was resected influenced the functional outcome. Abduction of the shoulder was to 45 degrees in most patients. The overall survival was 42% at ten years and that of the limb without amputation 93%. The survival of the prostheses using mechanical failure as the endpoint was 86.5% at 20 years. Endoprosthetic replacement of the proximal humerus is a predictable procedure providing reasonable function of the arm with a low rate of complications at long-term follow-up.

Abstract
A case of pencil-gore granuloma occurring 45 years after he initial injury is described. The clinical and radiological presentation was suggestive of a soft-tissue sarcoma. The diagnosis was confirmed by biopsy, which also revealed foreign body fragments which, on spectometric analysis, had high concentrations of carbon and aluminium.

Abstract
Ten patients underwent endoprosthetic replacement of the distal humerus for bone tumours over a period of 30 years. There were eight primary and two secondary tumours in four men and six women with a mean age of 47.5 years (15 to 76). The mean follow-up was eight years (9 months to 31 years). Four patients required further surgery, three having revision for aseptic loosening; two of these and one other later needing a rebushing. There were no cases of postoperative nerve palsy, infection, local recurrence or mechanical failure of the implant. Four patients died from their disease, all with the prosthesis functioning satisfactorily. At follow-up the mean flexion deformity of the elbow was 15 degrees (0 to 35) and the mean range of lexion was 115 degrees (110 to 135). The functional results showed a mean Toronto extremity salvage score of 73% of normal. Endoprosthetic replacement of the distal humerus and elbow is a satisfactory method of treating these rare tumours.

Abstract
Endoprosthetic replacements are commonly used for limb salvage following surgical excision of bone tumours. Advantages include initial reliability, rapid restoration of function and their ready availability. Potential long-term problems include loosening, infection and mechanical failure. Increasing problems may lead to the necessity for amputation; this paper assesses that risk. A total of 1,261 patients have undergone endoprosthetic replacements in our centre in the past 34 years, with a total of 6,507 patient years of follow up. A total of 112 patients have had subsequent amputation. The reasons for amputation were local recurrence in 71, infection in 38, mechanical failure in two and chronic pain in one. The proximal tibia had the greatest risk of amputation (n=38/245). The time to amputation varied from 2 days to 16 years, with a mean of 31 months. The risk of amputation decreased with time, although 10% took place after more than 5 years.

Abstract
We present the case of a 7-year-old boy with a haemorrhagic and spindle cell haemangiomas of the ring finger. The lesions appeared in a metachronous fashion initially in the distal phalanx and 16 months later in the proximal phalanx. Radiography revealed expansile lytic lesions of the phalanges. Haemorrhagic epithelioid and spindle cell haemangioma is a benign condition which, due to its unusual morphology, can be confused with more aggressive or malignant endothelial neoplasms. This condition with its possible multifocal presentation should be considered when diagnosing vascular lesions of bone in order that appropriate treatment can be implemented.

Abstract
We studied 153 patients with non-metastatic chondrosarcoma of bone to determine the risk factors for survival and local tumour control. The minimum follow-up was for five years; 52 patients had axial and 101 appendicular tumours. Surgical treatment was by amputation in 27 and limb-preserving surgery in 126. The cumulative rate of survival of all patients, at 10 and 15 years, was 70% and 63%, respectively; 40 patients developed a local recurrence between 3 and 87 months after surgery and 49 developed metastases. Local recurrence was associated with poor survival in patients with concomitant metastases but not in those without. On multivariate analysis independent risk factors for rates of survival include extracompartmental spread, development of local recurrence and high histological grade. Independent risk factors for local recurrence include inadequate surgical margins and tumour size greater than 10 cm. Location within the body, the type of surgery and the duration of symptoms are of no prognostic significance. Surgical excision with an oncologically wide margin provides the best prospect both for cure and local control in these patients.
