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
Surgical site infection (SSI) after soft-tissue sarcoma (STS) resection is a serious complication. The purpose of this retrospective study was to investigate the risk factors for SSI after STS resection, and to develop a nomogram that allows patient-specific risk assessment. A total of 547 patients with STS who underwent tumour resection between 2005 and 2021 were divided into a development cohort and a validation cohort. In the development cohort of 402 patients, the least absolute shrinkage and selection operator (LASSO) regression model was used to screen possible risk factors of SSI. To select risk factors and construct the prediction nomogram, multivariate logistic regression was used. The predictive power of the nomogram was evaluated by receiver operating curve (ROC) analysis in the validation cohort of 145 patients.Aims
Methods
The modern prevalence of primary tumours causing metastatic bone disease is ill-defined in the oncological literature. Therefore, the purpose of this study is to identify the prevalence of primary tumours in the setting of metastatic bone disease, as well as reported rates of pathological fracture, postoperative complications, 90-day mortality, and 360-day mortality for each primary tumour subtype. The Premier Healthcare Database was queried to identify all patients who were diagnosed with metastatic bone disease from January 2015 to December 2020. The prevalence of all primary tumour subtypes was tabulated. Rates of long bone pathological fracture, 90-day mortality, and 360-day mortality following surgical treatment of pathological fracture were assessed for each primary tumour subtype. Patient characteristics and postoperative outcomes were analyzed based upon whether patients had impending fractures treated prophylactically versus treated completed fractures.Aims
Methods
The primary objective of this study was to compare the postoperative infection rate between negative pressure wound therapy (NPWT) and conventional dressings for closed incisions following soft-tissue sarcoma (STS) surgery. Secondary objectives were to compare rates of adverse wound events and functional scores. In this prospective, single-centre, randomized controlled trial (RCT), patients were randomized to either NPWT or conventional sterile occlusive dressings. A total of 17 patients, with a mean age of 54 years (21 to 81), were successfully recruited and none were lost to follow-up. Wound reviews were undertaken to identify any surgical site infection (SSI) or adverse wound events within 30 days. The Toronto Extremity Salvage Score (TESS) and Musculoskeletal Tumor Society (MSTS) score were recorded as patient-reported outcome measures (PROMs).Aims
Methods
Tenosynovial giant cell tumour (TGCT) is one of the most common soft-tissue tumours of the foot and ankle and can behave in a locally aggressive manner. Tumour control can be difficult, despite the various methods of treatment available. Since treatment guidelines are lacking, the aim of this study was to review the multidisciplinary management by presenting the largest series of TGCT of the foot and ankle to date from two specialized sarcoma centres. The Oxford Tumour Registry and the Leiden University Medical Centre Sarcoma Registry were retrospectively reviewed for patients with histologically proven foot and ankle TGCT diagnosed between January 2002 and August 2019.Aims
Methods
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 limb salvage surgery (LSS), or amputation. A total of 69 patients with ankle sarcomas, treated between 1981 and 2017 at two tumour centres, were retrospectively reviewed (mean age at surgery: 46.3 years (SD 22.0); 31 females (45%)). Among these 69 patients 25 were analyzed prospectively (mean age at latest follow-up: 61.2 years (SD 20.7); 11 females (44%)), and assessed for mobility using the Prosthetic Limb Users Survey of Mobility (PLUS-M; for amputees only), the Toronto Extremity Salvage Score (TESS), and the University of California, Los Angeles (UCLA) Activity Score. Individual QoL was evaluated in these 25 patients using the five-level EuroQol five-dimension (EQ-5D-5L) and Fragebogen zur Lebenszufriedenheit/Questions on Life Satisfaction (FLZ).Aims
Methods
We have evaluated the survivorship, outcomes, and failures of an interlocking, reconstruction-mode stem-sideplate implant used to preserve the native hip joint and achieve proximal fixation when there is little residual femur during large endoprosthetic reconstruction of the distal femur. A total of 14 patients underwent primary or revision reconstruction of a large femoral defect with a short remaining proximal femur using an interlocking, reconstruction-mode stem-sideplate for fixation after oncological distal femoral and diaphyseal resections. The implant was attached to a standard endoprosthetic reconstruction system. The implant was attached to a standard endoprosthetic reconstruction system. None of the femoral revisions were amenable to standard cemented or uncemented stem fixation. Patient and disease characteristics, surgical history, final ambulatory statusAims
Methods
Although internal hemipelvectomy is associated with a high incidence of morbidity, especially wound complications, few studies have examined rates of wound complications in these patients or have identified factors associated with the consequences. The present study aimed to: 1) determine the rate of wound and other complications requiring surgery after internal hemipelvectomy; and 2) identify factors that affect the rate of wound complications and can be used to stratify patients by risk of wound complications. The medical records of 123 patients undergoing internal hemipelvectomy were retrospectively reviewed, with a focus on both overall complications and wound complications. Logistic regression analyses were performed to examine the association between host, tumour, and surgical factors and rates of postoperative wound complications.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
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. The primary aim of this study was to determine the morbidity
of a tibial strut autograft and characterize the rate of bony union
following its use. Patients and Methods. We retrospectively assessed a series of 104 patients from a single
centre who were treated with a tibial strut autograft of > 5 cm
in length. A total of 30 had a segmental reconstruction with continuity
of bone, 27 had a segmental reconstruction without continuity of
bone, 29 had an arthrodesis and 18 had a nonunion. Donor-site morbidity
was defined as any event that required a modification of the postoperative
management. Union was assessed clinically and radiologically at
a median of 36 months (IQR, 14 to 74). Results. Donor-site morbidity occurred in four patients (4%; 95% confidence
interval (CI) 1 to 10). One patient had a stress fracture of the
tibia, which healed with a varus deformity, requiring an osteotomy.
Two patients required evacuation of a
Few studies dealing with chondrosarcoma of the pelvis are currently
available. Different data about the overall survival and prognostic
factors have been published but without a detailed analysis of surgery-related complications.
We aimed to analyse the outcome of a series of pelvic chondrosarcomas
treated at a single institution, with particular attention to the
prognostic factors. Based on a competing risk model, our objective
was to identify risk factors for the development of complications. In a retrospective single-centre study, 58 chondrosarcomas (26
patients alive, 32 patients dead) of the pelvis were reviewed. The
mean follow-up was 13 years (one week to 23.1 years).Aims
Patients and Methods
The aims of this retrospective study were to report the feasibility
of using 3D-printing technology for patients with a pelvic tumour
who underwent reconstruction. A total of 35 patients underwent resection of a pelvic tumour
and reconstruction using 3D-printed endoprostheses between September
2013 and December 2015. According to Enneking’s classification of
bone defects, there were three Type I lesions, 12 Type II+III lesions,
five Type I+II lesions, two Type I+II+III lesions, ten type I+II+IV
lesions and three type I+II+III+IV lesions. A total of three patients
underwent reconstruction using an iliac prosthesis, 12 using a standard
hemipelvic prosthesis and 20 using a screw-rod connected hemipelvic
prosthesis.Aims
Patients and Methods
We investigated whether the presence of a pathological
fracture increased the risk of local recurrence in patients with
a giant cell tumour (GCT) of bone. We also assessed if curettage
is still an appropriate form of treatment in the presence of a pathological
fracture. We conducted a comprehensive review and meta-analysis
of papers which reported outcomes in patients with a GCT with and
without a pathological fracture at presentation. We computed the
odds ratio (OR) of local recurrence in those with and without a
pathological fracture. We selected 19 eligible papers for final analysis. This included
3215 patients, of whom 580 (18.0%) had a pathological fracture.
The pooled OR for local recurrence between patients with and without
a pathological fracture was 1.05 (95% confidence interval (CI) 0.66
to 1.67, p = 0.854). Amongst the subgroup of patients who were treated with
curettage, the pooled OR for local recurrence was 1.23 (95% CI 0.75
to 2.01, p = 0.417). A There is no difference in local recurrence rates between patients
who have a GCT of bone with and without a pathological fracture
at the time of presentation. The presence of a pathological fracture
should not preclude the decision to perform curettage as carefully
selected patients who undergo curettage can have similar outcomes
in terms of local recurrence to those without such a fracture. Cite this article:
We determined the efficacy of a devitalised autograft
(n = 13) and allograft (n = 16) cortical strut bone graft combined
with long-stem endoprosthetic reconstruction in the treatment of
massive tumours of the lower limb. A total of 29 patients (18 men:11
women, mean age 20.1 years (12 to 45) with a ratio of length of
resection to that of the whole prosthesis of >
50% were treated
between May 2003 and May 2012. The mean follow-up was 47 months
(15 to 132). The stem of the prosthesis was introduced through bone
graft struts filled with cement, then cemented into the residual
bone. Bone healing was achieved in 23 patients (86%). The mean Musculoskeletal
Tumour Society functional score was 85% (57 to 97). The five-year
survival rate of the endoprostheses was 81% (95% confidence intervals
67.3 to 92.3). The mean length of devitalised autografts and allografts
was 8.6 cm (5 to 15), which increased the ratio of the the length
of the stem of the prosthesis to that of the whole length of the
prosthesis from a theoretical 35% to an actual 55%. Cortical strut bone grafting and long-stem endoprosthetic reconstruction
is an option for treating massive segmental defects following resection
of a tumour in the lower limb. Patients can regain good function
with a low incidence of aseptic loosening. The strut graft and the
residual bone together serve as a satisfactory bony environment
for a revision prosthesis, if required, once union is achieved. Cite this article:
We report our early experience with the use of
a new prosthesis, the Modular Hemipelvic Prosthesis II, for reconstruction
of the hemipelvis after resection of a primary malignant peri-acetabular
tumour involving the sacroiliac joint. We retrospectively reviewed the outcome of 17 patients who had
undergone resection of a pelvic tumour and reconstruction with this
prosthesis between July 2002 and July 2010. One patient had a type I+II+III+IV resection (ilium + peri-acetabulum
+ pubis/ischium + sacrum) and 16 had a type I+II+IV resection (ilium
+ acetabulum + sacrum). The outcome was assessed at a mean follow-up
of 33 months (15 to 59). One patient was alive with disease, 11
were alive without disease and five had died of disease. The overall
five-year survival rate was 62.4%. Six patients had a local recurrence.
The mean Musculoskeletal Tumour Society score was 58% (33 to 77).
Deep infection occurred in two patients, problems with wound healing
in five and dislocation in one. For patients with a primary malignant peri-acetabular sarcoma
involving the sacroiliac joint, we believe that this new prosthesis
is a viable option for reconstruction of the bony defect left following
resection of the tumour. It results in a satisfactory functional
outcome with an acceptable rate of complications. Cite this article:
Resection of malignant bony tumours of the pelvis
creates large bone and soft-tissue defects, and is frequently associated
with complications such as wound dehiscence and deep infection.
We present the results of six patients in whom a rectus abdominis
myocutaneous (RAM) flap was used following resection of a malignant
tumour of the pelvis. Bony reconstruction was performed using a
constrained hip tumour prosthesis in three patients, vascularised
fibular graft in two and frozen autograft in one. At a mean follow-up
of 63 months (16 to 115), no patients had a problem with the wound. Immediate reconstruction using a RAM flap may be used after resection
of a malignant tumour of the pelvis to provide an adequate volume
of tissue to eliminate the dead space, cover the exposed bone or
implants with well-vascularised soft tissue and to reduce the risk
of complications. Cite this article:
We investigated the functional outcome in patients
who underwent reverse shoulder replacement (RSR) after removal of
a tumour of the proximal humerus. A total of 16 patients (ten women
and six men) underwent this procedure between 1998 and 2011 in our
hospital. Five patients died and one was lost to follow-up. Ten
patients were available for review at a mean follow-up of 46 months
(12 to 136). Eight patients had a primary and two patients a secondary
bone tumour. At final follow up the mean range of active movement was: abduction
78° (30° to 150°); flexion 98° (45° to 180°); external rotation
32° (10° to 60°); internal rotation 51° (10° to 80°). The mean Musculoskeletal
Tumor Society score was 77% (60% to 90%) and the mean Toronto Extremity
Salvage Score was 70% (30% to 91%). Two patients had a superficial
infection and one had a deep infection and underwent a two-stage
revision procedure. In two patients there was loosening of the RSR;
one dislocated twice. All patients had some degree of atrophy or
pseudo-atrophy of the deltoid muscle. Use of a RSR in patients with a tumour of the proximal humerus
gives acceptable results. Cite this article:
It is important to be able to identify patients
with an increased risk of venous thromboembolism (VTE) in order
to minimise the risk of an event. We investigated the incidence
and risk factors for post-operative VTE in 168 consecutive patients
with a malignancy of the lower limb. The period of study included
ten months before and 12 months after the introduction of chemical
thromboprophylaxis. All data about the potential risk factors were identified
and classified into three groups (patient-, surgery- and tumour-related).
The outcome measure was a thromboembolic event within 90 days of
surgery. Of the 168 patients, eight (4.8%) had a confirmed symptomatic
deep-vein thrombosis and one (0.6%) a fatal pulmonary embolism.
Of the 28 variables tested, age >
60 years, higher American Society
of Anesthesiologists grade and metastatic tumour were independent
risk factors for VTE. The overall rate of symptomatic VTE was not significantly
different between patients who received chemical thromboprophylaxis
and those who did not. Knowledge of these risk factors may be of
value in improving the surgical outcome of patients with a malignancy
of the lower limb. Cite this article:
