Endoprosthetic reconstruction following distal femur tumour resection has been widely advocated. In this paper, we present the design of an uncemented endoprosthesis system featuring a short, curved stem, with the goal of enhancing long-term survivorship and functional outcomes. This study involved patients who underwent implantation of an uncemented distal femoral endoprosthesis with a short and curved stem between 2014 and 2019. Functional outcomes were assessed using the 1993 version of the Musculoskeletal Tumour Society (MSTS-93) score. Additionally, we quantified five types of complications and assessed osseointegration radiologically. The survivorship of the endoprosthesis was evaluated according to two endpoints. A total of 134 patients with a median age of 26 years (IQR 16 to 41) were included in our study. The median follow-up time was 61 months (IQR 56 to 76), and the median functional MSTS-93 was 83% (IQR 73 to 91) postoperatively.Aims
Methods
Limb salvage surgery (LSS) is the primary treatment option for primary bone malignancy. It involves the removal of bone and tissue, followed by reconstruction with endoprosthetic replacements (EPRs) to prevent amputation. Trabecular metal (TM) collars have been developed to encourage bone ingrowth (osseointegration (OI)) into EPRs. The primary aim of this study was to assess whether OI occurs when TM collars are used in EPRs for tumour. A total of 124 patients from July 2010 to August 2021 who underwent an EPR for tumour under the West of Scotland orthopaedic oncology team were identified. Overall, 81 patients (65%) met the inclusion criteria, and two consultants independently analyzed radiographs at three and 12 months, as well as the last radiograph, using a modified version of the Stanford Radiological Assessment System.Aims
Methods
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. 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 limb salvage or amputation.Aims
Methods
We have previously reported cryoablation-assisted joint-sparing surgery for osteosarcoma with epiphyseal involvement. However, it is not clear whether this is a comparable alternative to conventional joint arthroplasty in terms of oncological and functional outcomes. A total of 22 patients who had localized osteosarcoma with epiphyseal involvement around the knee and underwent limb salvage surgery were allocated to joint preservation (JP) group and joint arthroplasty (JA) group. Subjects were followed with radiographs, Musculoskeletal Tumor Society (MSTS) score, and clinical evaluations at one, three, and five years postoperatively.Aims
Methods
Local recurrence remains a challenging and common problem following curettage and joint-sparing surgery for giant cell tumour of bone (GCTB). We previously reported a 15% local recurrence rate at a median follow-up of 30 months in 20 patients with high-risk GCTB treated with neoadjuvant Denosumab. The aim of this study was to determine if this initial favourable outcome following the use of Denosumab was maintained with longer follow-up. Patients with GCTB of the limb considered high-risk for unsuccessful joint salvage, due to minimal periarticular and subchondral bone, large soft tissue mass, or pathological fracture, were treated with Denosumab followed by extended intralesional curettage with the goal of preserving the joint surface. Patients were followed for local recurrence, metastasis, and secondary sarcoma.Aims
Methods
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
Patients and Methods
Iliac wing (Type I) and iliosacral (Type I/IV) pelvic resections for a primary bone tumour create a large segmental defect in the pelvic ring. The management of this defect is controversial as the surgeon may choose to reconstruct it or not. When no reconstruction is undertaken, the residual ilium collapses back onto the remaining sacrum forming an iliosacral pseudarthrosis. The aim of this study was to evaluate the long-term oncological outcome, complications, and functional outcome after pelvic resection without reconstruction. Between 1989 and 2015, 32 patients underwent a Type I or Type I/IV pelvic resection without reconstruction for a primary bone tumour. There were 21 men and 11 women with a mean age of 35 years (15 to 85). The most common diagnosis was chondrosarcoma (50%, n = 16). Local recurrence-free, metastasis-free, and overall survival were assessed using the Kaplan-Meier method. Patient function was evaluated using the Musculoskeletal Tumour Society (MSTS) and Toronto Extremity Salvage Score (TESS).Aims
Methods
The aim of this study was to present the long-term surgical outcomes, complications, implant survival, and causes of implant failure in patients treated with the modified Harrington procedure using antegrade large diameter pins. A cohort of 50 consecutive patients who underwent the modified Harrington procedure for periacetabular metastasis or haematological malignancy between January 1996 and April 2018 were studied. The median follow-up time for all survivors was 3.2 years (interquartile range 0.9 to 7.6 years).Aims
Patients and Methods
The aim of this study was to evaluate the prosthesis characteristics and associated conditions that may modify the survival of total femoral endoprosthetic replacements (TFEPR). In all, 81 patients treated with TFEPR from 1976 to 2017 were retrospectively evaluated and failures were categorized according to the Henderson classification. There were 38 female patients (47%) and 43 male patients (53%) with a mean age at diagnosis of 43 years (12 to 86). The mean follow-up time was 10.3 years (0 to 31.7). A survival analysis was performed followed by univariate and multivariate Cox regression to identify independent implant survival factors.Aims

The aims of this study were to evaluate the long-term outcome
of surgery for bone or soft-tissue metastases from renal cell carcinoma
(RCC) and to determine factors that affect prognosis. Between 1993 and 2014, 58 patients underwent surgery for bone
or soft-tissue metastases from RCC at our hospital. There were 46
men and 12 women with a mean age of 60 years (25 to 84). The mean
follow-up period was 52 months (1 to 257). The surgical sites included
the spine (33 patients), appendicular skeleton (ten patients), pelvis (eight
patients), thorax (four patients), and soft tissue (three patients).

Patients and Methods
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
Patients and Methods
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. 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
Society (MSTS) scoring system, the Toronto Extremity Salvage Score
(TESS) and Quality of Life-C30 (QLQ-30) measures. Radiographic outcomes
were assessed using the International Society of Limb Salvage (ISOLS)
radiographic scoring system.Aims
Patients and Methods
The aim of the study was to investigate the controversial issue
of whether the pelvic ring should be reconstructed following resection
of the sarcomas of the ilium. From our database, we identified 64 patients who underwent excision
of a tumour involving the ilium between 1976 and 2015. A total of
35 underwent complete resection, of whom 24 were reconstructed with
a non-vascularised fibula graft, and four with extracorporeal irradiation
and reimplantation. A total of 29 patients had a partial resection.
The mean follow-up was 9.2 years (1.1 to 25.6). Functional outcomes
were assessed using the Toronto Extremity Salvation Score (TESS)
at final follow-up. In all, 32 patients (50%) had a chondrosarcoma.Aims
Patients and Methods
In this cross sectional study, the impact and the efficacy of a surveillance programme for sarcomas of the extremities was analysed. All patients who had treatment with curative intent for a high-grade sarcoma and were diagnosed before 2014 were included and followed for a minimum of two years.Objectives
Methods
As tumours of bone and soft tissue are rare, multicentre prospective collaboration is essential for meaningful research and evidence-based advances in patient care. The aim of this study was to identify barriers and facilitators encountered in large-scale collaborative research by orthopaedic oncological surgeons involved or interested in prospective multicentre collaboration. All surgeons who were involved, or had expressed an interest, in the ongoing Prophylactic Antibiotic Regimens in Tumour Surgery (PARITY) trial were invited to participate in a focus group to discuss their experiences with collaborative research in this area. The discussion was digitally recorded, transcribed and anonymised. The transcript was analysed qualitatively, using an analytic approach which aims to organise the data in the language of the participants with little theoretical interpretation.Objectives
Methods
Giant cell tumours (GCTs) of the small bones
of the hands and feet are rare. Small case series have been published but
there is no consensus about ideal treatment. We performed a systematic
review, initially screening 775 titles, and included 12 papers comprising
91 patients with GCT of the small bones of the hands and feet. The
rate of recurrence across these publications was found to be 72%
(18 of 25) in those treated with isolated curettage, 13% (2 of 15)
in those treated with curettage plus adjuvants, 15% (6 of 41) in
those treated by resection and 10% (1 of 10) in those treated by
amputation. We then retrospectively analysed 30 patients treated for GCT
of the small bones of the hands and feet between 1987 and 2010 in
five specialised centres. The primary treatment was curettage in
six, curettage with adjuvants (phenol or liquid nitrogen with or
without polymethylmethacrylate (PMMA)) in 18 and resection in six.
We evaluated the rate of complications and recurrence as well as
the factors that influenced their functional outcome. At a mean follow-up of 7.9 years (2 to 26) the rate of recurrence
was 50% (n = 3) in those patients treated with isolated curettage,
22% (n = 4) in those treated with curettage plus adjuvants and 17%
(n = 1) in those treated with resection (p = 0.404). The only complication
was pain in one patient, which resolved after surgical removal of remnants
of PMMA. We could not identify any individual factors associated
with a higher rate of complications or recurrence. The mean post-operative
Musculoskeletal Tumor Society scores were slightly higher after
intra-lesional treatment including isolated curettage and curettage
plus adjuvants (29 (20 to 30)) compared with resection (25 (15 to
30)) (p = 0.091). Repeated curettage with adjuvants eventually resulted
in the cure for all patients and is therefore a reasonable treatment
for both primary and recurrent GCT of the small bones of the hands
and feet. Cite this article:
We retrospectively studied 14 patients with proximal and diaphyseal tumours and disappearing bone (Gorham’s) disease of the humerus treated with wide resection and reconstruction using an allograft-resurfacing composite (ARC). There were ten women and four men, with a mean age of 35 years (8 to 69). At a mean follow-up of 25 months (10 to 89), two patients had a fracture of the allograft. In one of these it was revised with a similar ARC and in the other with an intercalary prosthesis. A further patient had an infection and a fracture of the allograft that was revised with a megaprosthesis. In all patients with an ARC, healing of the ARC-host bone interface was observed. One patient had failure of the locking mechanism of the total elbow replacement. The mean post-operative Musculoskeletal Tumor Society score for the upper extremity was 77% (46.7% to 86.7%), which represents good and excellent results; one patient had a poor result (46.7%). In the short term ARC effectively relieves pain and restores shoulder function in patients with wide resection of the proximal humerus. Fracture and infection remain significant complications.
Massive endoprostheses using a cemented intramedullary stem are widely used to allow early resumption of activity after surgery for tumours. The survival of the prosthesis varies with the anatomical site, the type of prosthesis and the mode of fixation. Revision surgery is required in many cases because of aseptic loosening. Insertion of a second cemented endoprosthesis may be difficult because of the poor quality of the remaining bone, and loosening recurs quickly. We describe a series of 14 patients with triplate fixation in difficult revision or joint-sparing tumour surgery with a minimum follow-up of four years. The triplate design incorporated well within a remodelled cortex to achieve osseomechanical integration with all patients regaining their original level of function within five months. Our preliminary results suggest that this technique may provide an easy, biomechanically friendly alternative to insertion of a further device with an intramedullary stem, which has a shorter lifespan in revision or joint-sparing tumour surgery. A short segment of bone remaining after resection of a tumour will not accept an intramedullary stem, but may be soundly fixed using this method.
