We first sought to compare survival for patients treated surgically for solitary and multiple metastases in the appendicular skeleton, and second, to explore the role of complete and incomplete resection (R0 and R1/R2) in patients with a solitary bony metastasis in the appendicular skeleton. We conducted a retrospective study on a population-based cohort of all adult patients treated surgically for bony metastases of the appendicular skeleton between January 2014 and December 2019. We excluded patients in whom the status of bone metastases and resection margin was unknown. Patients were followed until the end of the study or to their death. We had no loss to follow-up. We used Kaplan-Meier analysis (with log-rank test) to evaluate patient survival. We identified 506 operations in 459 patients. A total of 120 operations (in 116 patients) were for solitary metastases and 386 (in 345 patients) for multiple metastases. Of the 120 operations, 70 (in 69 patients) had no/an unknown status of visceral metastases (solitary group) and 50 (in 49 patients) had visceral metastases. In the solitary group, 45 operations (in 44 patients) were R0 (resections for cure or complete remission) and 25 (in 25 patients) were R1/R2 (resections leaving microscopic or macroscopic tumour, respectively). The most common types of cancer in the solitary group were kidney (n = 27), lung (n = 25), and breast (n = 20).Aims
Methods
The proximal tibia (PT) is the anatomical site most frequently affected by primary bone tumours after the distal femur. Reconstruction of the PT remains challenging because of the poor soft-tissue cover and the need to reconstruct the extensor mechanism. Reconstructive techniques include implantation of massive endoprosthesis (megaprosthesis), osteoarticular allografts (OAs), or allograft-prosthesis composites (APCs). This was a retrospective analysis of clinical data relating to patients who underwent proximal tibial arthroplasty in our regional bone tumour centre from 2010 to 2018.Aims
Methods
The aim of this study was to assess the clinical and radiological outcomes of an antiprotrusio acetabular cage (APC) when used in the surgical treatment of periacetabular bone metastases. This retrospective cohort study using a prospectively collected database involved 56 patients who underwent acetabular reconstruction for periacetabular bone metastases or haematological malignancy using a single APC between January 2009 and 2020. The mean follow-up was 20 months (1 to 143). The primary outcome measure was implant survival. Postoperative radiographs were analyzed for loosening and failure. Patient and implant survival were assessed using a competing risk analysis. Secondary parameters included primary malignancy, oncological treatment, surgical factors, length of stay in hospital, and postoperative complications.Aims
Methods
The incidence of bone metastases is between 20% to 75% depending on the type of cancer. As treatment improves, the number of patients who need surgical intervention is increasing. Identifying patients with a shorter life expectancy would allow surgical intervention with more durable reconstructions to be targeted to those most likely to benefit. While previous scoring systems have focused on surgical and oncological factors, there is a need to consider comorbidities and the physiological state of the patient, as these will also affect outcome. The primary aim of this study was to create a scoring system to estimate survival time in patients with bony metastases and to determine which factors may adversely affect this. This was a retrospective study which included all patients who had presented for surgery with metastatic bone disease. The data collected included patient, surgical, and oncological variables. Univariable and multivariable analysis identified which factors were associated with a survival time of less than six months and less than one year. A model to predict survival based on these factors was developed using Cox regression.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
There is an increased risk of dislocation of the hip after the resection of a periacetabular tumour and endoprosthetic reconstruction of the defect in the hemipelvis. The aim of this study was to determine the rate and timing of dislocation and to identify its risk factors. To determine the dislocation rate, we conducted a retrospective single-institution study of 441 patients with a periacetabular tumour who had undergone a standard modular hemipelvic endoprosthetic reconstruction between 2003 and 2019. After excluding ineligible patients, 420 patients were enrolled. Patient-specific, resection-specific, and reconstruction-specific variables were studied using univariate and multivariate analyses.Aims
Methods
The purpose of this study was to develop a prognostic model for
predicting survival of patients undergoing surgery owing to metastatic
bone disease (MBD) in the appendicular skeleton. We included a historical cohort of 130 consecutive patients (mean
age 64 years, 30 to 85; 76 females/54 males) who underwent joint
arthroplasty surgery (140 procedures) owing to MBD in the appendicular
skeleton during the period between January 2003 and December 2008.

Methods
Resection of the proximal humerus for the primary malignant bone
tumour sometimes requires We reviewed 45 patients who had undergone resection of a primary
malignant tumour of the proximal humerus. There were 29 in the deltoid
sparing group and 16 in the deltoid resecting group. Imaging studies
were reviewed to assess tumour extension and soft-tissue involvement.
The presence of a fat rim separating the tumour from the deltoid
on MRI was particularly noted. The cumulative probability of local
recurrence was calculated in a competing risk scenario.Aims
Patients and Methods
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:
