We analyzed the long-term outcomes of patients observed over ten years after resection en bloc and reconstruction with extracorporeal irradiated autografts This retrospective study included 27 patients who underwent resection en bloc and reimplantation of an extracorporeal irradiated autograft. The mean patient age and follow-up period were 31.7 years (9 to 59) and 16.6 years (10.3 to 24.3), respectively. The most common diagnosis was osteosarcoma (n = 10), followed by chondrosarcoma (n = 6). The femur (n = 13) was the most frequently involved site, followed by the tibia (n = 7). There were inlay grafts in five patients, intercalary grafts in 15 patients, and osteoarticular grafts in seven patients. Functional outcome was evaluated with the Musculoskeletal Tumor Society (MSTS) scoring system.Aims

Aims. We present a retrospective review of patients treated with extracorporeally
irradiated allografts for primary and secondary bone tumours with
the mid- and long-term survivorship and the functional and radiographic
outcomes. Patients and Methods. A total of 113 of 116 (97.4%) patients who were treated with
extracorporeally irradiated allografts between 1996 and 2014 were
followed up. Forms of treatment included reconstructions, prostheses
and composite reconstructions, both with and without vascularised
grafts. Survivorship was determined by the Kaplan-Meier method.
Clinical outcomes were assessed using the Musculoskeletal Tumor

Bone sarcomas are rare cancers and orthopaedic
surgeons come across them infrequently, sometimes unexpectedly during
surgical procedures. We investigated the outcomes of patients who
underwent a surgical procedure where sarcomas were found unexpectedly
and were subsequently referred to our unit for treatment. We identified
95 patients (44 intra-lesional excisions, 35 fracture fixations,
16 joint replacements) with mean age of 48 years (11 to 83); 60%
were males (n = 57). Local recurrence arose in 40% who underwent
limb salvage surgery versus 12% who had an amputation.
Despite achieving local control, overall survival was worse for
patients treated with amputation rather than
We treated 50 patients with bony malignancy by en-bloc resection, extracorporeal irradiation with 50 Gy and re-implantation of the bone segment. The mean survivor follow-up was 38 months (12 to 92) when 42 patients were alive and without disease. There were four recurrences. The functional results were good according to the Mankin score (17 excellent, 13 good, nine fair, three failures), the Musculoskeletal Tumour Society score (mean 77) and the Toronto Extremity Salvage score (mean 81). There was solid union, but bone resorption was seen in some cases. The dose of radiation was lethal to all cells and produced a dead autograft of perfect fit. Extracorporeal irradiation is a useful technique for

We report the results of distraction osteogenesis (callotasis) for the reconstruction of extensive defects after the excision of skeletal tumours in the limbs. Bone transport was performed in ten patients (five osteosarcomas and five giant-cell tumours), shortening-distraction in three (two osteosarcomas and one Ewing’s sarcoma), and distraction osteogenesis combined with an intramedullary nail to reduce the time of external fixation in six (three osteosarcomas, two chondro-sarcomas, and one malignant fibrous histiocytoma). The mean length of the defects after excision of the lesion was 8.4 cm. The mean external fixation index was 39.5 days/cm for the group treated by bone transport, 34.1 days/cm for the shortening-distraction group, and 24.0 days/cm for the group treated by distraction and an intramedullary nail. Functional evaluation gave excellent results in 12 patients, good in five and fair in two. There were ten complications in 19 patients, all of which were successfully treated. We also classified reconstruction using distraction osteogenesis into five types based on the location of the defects after resection of the tumour: type 1, diaphyseal; type 2, metaphyseal; type 3, epiphyseal; type 4, subarticular reconstruction; and type 5, arthrodesis. Our results suggest that reconstruction using distraction osteogenesis provides bone which will develop sufficient biomechanical strength and durability. It is beneficial in patients with an expectation of long-term survival and in growing children.
Aims. We retrospectively report our experience of managing 30 patients with a primary malignant tumour of the distal tibia; 25 were treated by
We treated four patients with periacetabular malignant tumours by pelvic reconstruction with a free vascularised fibular graft after resection of the tumour. The mean follow-up period was 32 months (9 to 39). The diagnosis was chondrosarcoma in three patients and osteosarcoma in one. In two patients total resection of the hemipelvis was required and in the other two less, but still massive, resection was undertaken. All were treated with an immediate free vascularised fibular graft which included arthrodesis of the hip and reconstruction of the pelvic ring. One patient died. The other three have remained free from recurrence. Solid union of the graft was achieved between four and 14 months after surgery. Shortening of the involved limbs was less than 2 cm. The patients had no pain and were independent walkers without external support. Emotional acceptance was satisfactory. Our results suggest that reconstruction with the use of a free vascularised graft is an alternative to other types of reconstructive procedure after resection of periacetabular tumours.
Aims. The aims of the study were to analyze differences in surgical and oncological outcomes, as well as quality of life (QoL) and function in patients with ankle sarcomas undergoing three forms of surgical treatment, minor or major
Opinion remains divided as to whether the development
of pathological fracture affects the prognosis of patients with
an osteosarcoma of the extremities. We conducted a comprehensive systematic review and meta-analysis
of papers which reported the outcomes of osteosarcoma patients with
and without a pathological fracture. There were eight eligible papers
for final analysis which reported on 1713 patients, of whom 303
(17.7%) had a pathological fracture. The mean age for 1464 patients in
six studies was 23.2 years old (2 to 82). The mean follow-up for
1481 patients in seven studies was 90.1 months (6 to 240). The pooled estimates of local recurrence rates in osteosarcoma
patients with and without pathological fractures were 14.4% (8.7
to 20.0) versus 11.4% (8.0 to 14.8). The pooled
estimate of relative risk was 1.39 (0.89 to 2.20). The pooled estimates
of five-year event-free survival rates in osteosarcoma patients
with and without a pathological fracture were 49.3% (95% CI 43.6
to 54.9) versus 66.8% (95% CI 60.7 to 72.8). The
pooled estimate of relative risk was 1.33 (1.12 to 1.59). There
was no significant difference in the rate of local recurrence between
patients who were treated by amputation or
Aims. Following the resection of an extensive amount of bone in the
treatment of a tumour, the residual segment may be insufficient
to accept a standard length intramedullary cemented stem. Short-stemmed
endoprostheses conceivably have an increased risk of aseptic loosening.
Extra-cortical plates have been added to minimise this risk by supplementing
fixation. The aim of this study was to investigate the survivorship
of short-stemmed endoprostheses and extra-cortical plates. Patients and Methods. The study involved 37 patients who underwent

The scapula is a rare site for a primary bone tumour. Only a small number of series have studied patient outcomes after treatment. Previous studies have shown a high rate of recurrence, with functional outcomes determined by the preservation of the glenohumeral joint and deltoid. The purpose of the current study was to report the outcome of patients who had undergone tumour resection that included the scapula. We reviewed 61 patients (37 male, 24 female; mean age 42 years (SD 19)) who had undergone resection of the scapula. The most common resection was type 2 (n = 34) according to the Tikhoff-Linberg classification, or type S1A (n = 35) on the Enneking classification.Aims
Methods
We analysed the outcome of patients with primary
non-metastatic diaphyseal sarcomas who had en bloc resection with
preservation of the adjoining joints and reconstruction with re-implantation
of sterilised tumour bone after extracorporeal radiation (50 Gy).
Between March 2005 and September 2009, 32 patients (16 Ewing’s sarcoma
and 16 osteogenic sarcoma) with a mean age of 15 years (2 to 35)
underwent this procedure. The femur was the most common site in
17 patients, followed by the tibia in 11, humerus in three and ulna
in one. The mean resected length of bone was 19 cm (10 to 26). A
total of 31 patients were available at a mean follow-up of 34 months
(12 to 74). The mean time to union for all osteotomy sites was 7.3
months (3 to 28): metaphyseal osteotomy sites united quicker than
diaphyseal osteotomy sites (5.8 months (3 to 10) versus 9.5
months (4 to 28)). There were three local recurrences, all in soft-tissue
away from irradiated graft. At the time of final follow-up, 19 patients
were free of disease, one was alive with disease and 11 had died
of disease. The mean Musculoskeletal Tumor Society Score for 29
patients evaluated at the last follow-up was 26 (9 to 30). Extracorporeal irradiation is an oncologically safe and inexpensive

Dislocation rates are reportedly lower in patients requiring
proximal femoral hemiarthroplasty than for patients undergoing hip
arthroplasty for neoplasia. Without acetabular replacement, pain
due to acetabular wear necessitating revision surgery has been described.
We aimed to determine whether wear of the native acetabulum following
hemiarthroplasty necessitates revision surgery with secondary replacement
of the acetabulum after proximal femoral replacement (PFR) for tumour
reconstruction. We reviewed 100 consecutive PFRs performed between January 2003
and January 2013 without acetabular resurfacing. The procedure was
undertaken in 74 patients with metastases, for a primary bone tumour
in 20 and for myeloma in six. There were 48 male and 52 female patients,
with a mean age of 61.4 years (19 to 85) and median follow-up of
two years (interquartile range (IQR) 0.5 to 3.7 years). In total,
52 patients presented with a pathological fracture and six presented
with failed fixation of a previously instrumented pathological fracture.Aims

Aims. Current literature suggests that survival outcomes and local recurrence rates of primary soft-tissue sarcoma diagnosed in the very elderly age range, (over 90 years), are comparable with those in patients diagnosed under the age of 75 years. Our aim is to quantify these outcomes with a view to rationalizing management and follow-up for very elderly patients. Methods. Retrospective access to our prospectively maintained oncology database yielded a cohort of 48 patients across 23 years with a median follow-up of 12 months (0 to 78) and mean age at diagnosis of 92 years (90 to 99). Overall, 42 of 48 of 48 patients (87.5%) were managed surgically with either
