The ulna is an extremely rare location for primary bone tumours of the elbow in paediatrics. Although several reconstruction options are available, the optimal reconstruction method is still unknown due to the rarity of proximal ulna tumours. In this study, we report the outcomes of osteoarticular ulna allograft for the reconstruction of proximal ulna tumours. Medical profiles of 13 patients, who between March 2004 and November 2021 underwent osteoarticular ulna allograft reconstruction after the resection of the proximal ulna tumour, were retrospectively reviewed. The outcomes were measured clinically by the assessment of elbow range of motion (ROM), stability, and function, and radiologically by the assessment of allograft-host junction union, recurrence, and joint degeneration. The elbow function was assessed objectively by the Musculoskeletal Tumor Society (MSTS) score and subjectively by the Toronto Extremity Salvage Score (TESS) and Mayo Elbow Performance Score (MEPS) questionnaire.Aims

Venous tumour thrombus (VTT) is a rare finding in osteosarcoma. Despite the high rate of VTT in osteosarcoma of the pelvis, there are very few descriptions of VTT associated with extrapelvic primary osteosarcoma. We therefore sought to describe the prevalence and presenting features of VTT in osteosarcoma of both the pelvis and the limbs. Records from a single institution were retrospectively reviewed for 308 patients with osteosarcoma of the pelvis or limb treated between January 2000 and December 2022. Primary lesions were located in an upper limb (n = 40), lower limb (n = 198), or pelvis (n = 70). Preoperative imaging and operative reports were reviewed to identify patients with thrombi in proximity to their primary lesion. Imaging and histopathology were used to determine presence of tumour within the thrombus.Aims
Methods
We performed a systematic literature review to define features of patients, treatment, and biological behaviour of multicentric giant cell tumour (GCT) of bone. The search terms used in combination were “multicentric”, “giant cell tumour”, and “bone”. Exclusion criteria were: reports lacking data, with only an abstract; papers not reporting data on multicentric GCT; and papers on multicentric GCT associated with other diseases. Additionally, we report three patients treated under our care.Aims
Methods
Dislocation of the hip remains a major complication after periacetabular tumour resection and endoprosthetic reconstruction. The position of the acetabular component is an important modifiable factor for surgeons in determining the risk of postoperative dislocation. We investigated the significance of horizontal, vertical, and sagittal displacement of the hip centre of rotation (COR) on postoperative dislocation using a CT-based 3D model, as well as other potential risk factors for dislocation. A total of 122 patients who underwent reconstruction following resection of periacetabular tumour between January 2011 and January 2020 were studied. The risk factors for dislocation were investigated with univariate and multivariate logistic regression analysis on patient-specific, resection-specific, and reconstruction-specific variables.Aims
Methods
The modified Glasgow Prognostic Score (mGPS) uses preoperative CRP and albumin to calculate a score from 0 to 2 (2 being associated with poor outcomes). mGPS is validated in multiple carcinomas. To date, its use in soft-tissue sarcoma (STS) is limited, with only small cohorts reporting that increased mGPS scores correlates with decreased survival in STS patients. This retrospective multicentre cohort study identified 493 STS patients using clinical databases from six collaborating hospitals in three countries. Centres performed a retrospective data collection for patient demographics, preoperative blood results (CRP and albumin levels and neutrophil, leucocyte, and platelets counts), and oncological outcomes (disease-free survival, local, or metastatic recurrence) with a minimum of two years' follow-up.Aims
Methods
Surgery is often indicated in patients with metastatic bone disease (MBD) to improve pain and maximize function. Few studies are available which report on clinically meaningful outcomes such as quality of life, function, and pain relief after surgery for MBD. This is the published protocol for the Bone Metastasis Audit — Patient Reported Outcomes (BoMA-PRO) multicentre MBD study. The primary objective is to ascertain patient-reported quality of life at three to 24 months post-surgery for MBD. This will be a prospective, longitudinal study across six UK orthopaedic centres powered to identify the influence of ten patient variables on quality of life at three months after surgery for MBD. Adult patients managed for bone metastases will be screened by their treating consultant and posted out participant materials. If they opt in to participate, they will receive questionnaire packs at regular intervals from three to 24 months post-surgery and their electronic records will be screened until death or five years from recruitment. The primary outcome is quality of life as measured by the European Organisation for Research and the Treatment of Cancer Quality of Life questionnaire (EORTC-QLQ) C30 questionnaire. The protocol has been approved by the Newcastle & North Tyneside 2 Research Ethics Committee (REC ref 19/NE/0303) and the study is funded by the Royal College of Physicians and Surgeons of Glasgow (RCPSG) and the Association for Cancer Surgery (BASO-ACS).Aims

The aim of this study was to report the outcomes of patients who underwent definitive surgery for secondary chondrosarcomas arising from osteochondromas. A total of 51 patients with secondary chondrosarcomas occurring from osteochondromas were reviewed. Median age was 36 years (interquartile range (IQR) 15 to 82). Median follow-up was 6.9 years (IQR 2.8 to 10.6). The pelvis was the most commonly affected site (59%). Histological grades were grade I in 35 (69%), grade II in 13 (25%), and grade III in three patients (6%).Aims
Patients and Methods
The aim of this study was to identify factors that determine outcomes of treatment for patients with chondroblastic osteosarcomas (COS) of the limbs and pelvis. The authors carried out a retrospective review of prospectively collected data from 256 patients diagnosed between 1979 and 2015. Of the 256 patients diagnosed with COS of the pelvis and the limbs, 147 patients (57%) were male and 109 patients (43%) were female. The mean age at presentation was 20 years (0 to 90).Aims
Patients and Methods
The purpose of this study was to investigate the potential for achieving local and systemic control after local recurrence of a chondrosarcoma of bone A total of 126 patients with local recurrence (LR) of chondrosarcoma (CS) of the pelvis or a limb bone were identified from a prospectively maintained database, between 1990 and 2015 at the Royal Orthopaedic Hospital, Birmingham, United Kingdom. There were 44 female patients (35%) and 82 male patients (65%) with a mean age at the time of LR of 56 years (13 to 96). The 126 patients represented 24.3% of the total number of patients with a primary CS (519) who had been treated during this period. Clinical data collected at the time of primary tumour and LR included the site (appendicular, extremity, or pelvis); primary and LR tumour size (in centimetres); type of operation at the time of primary or LR (limb-salvage or amputation); surgical margin achieved at resection of the primary tumour and the LR; grade of the primary tumour and the LR; gender; age; and oncological outcomes, including local recurrence-free survival and disease-specific survival. A minimum two years’ follow-up and complete histopathology records were available for all patients included in the study.Aims

The aim of this study was to evaluate the surgical management and outcome of patients with an acral soft-tissue sarcoma of the hand or foot. We identified 63 patients with an acral soft-tissue sarcoma who presented to our tertiary referral sarcoma service between 2000 and 2016. There were 35 men and 28 women with a mean age of 49 years (Aims
Patients and Methods
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
Pelvic reconstruction after the resection of a tumour around
the acetabulum is a challenging procedure due to the complex anatomy
and biomechanics. Several pelvic endoprostheses have been introduced,
but the rates of complication remain high. Our aim was to review
the use of a stemmed acetabular pedestal cup in the management of
these patients. The study involved 48 patients who underwent periacetabular reconstruction
using a stemmed pedestal cup (Schoellner cup; Zimmer Biomet Inc.,
Warsaw, Indiana) between 2000 and 2013. The indications for treatment included
a primary bone tumour in 27 patients and metastatic disease in 21
patients. The mean age of the patients at the time of surgery was
52 years (16 to 83).Aims
Patients and Methods
To assess complications and failure mechanisms of osteoarticular
allograft reconstructions for primary bone tumours. We retrospectively evaluated 38 patients (28 men, 74%) who were
treated at our institution with osteoarticular allograft reconstruction
between 1989 and 2010. Median age was 19 years (interquartile range
14 to 32). Median follow-up was 19.5 years (95% confidence interval
(CI) 13.0 to 26.1) when 26 patients (68%) were alive. In addition, we
systematically searched the literature for clinical studies on osteoarticular
allografts, finding 31 studies suitable for analysis. Results of
papers that reported on one site exclusively were pooled for comparison.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
The aim of this study was to identify any progression between
benign osteofibrous dysplasia (OFD), OFD-like adamantinoma and malignant
adamantinoma, and to investigate the rates of local recurrence,
metastases and survival, in order to develop treatment algorithms
for each. A single institution retrospective review of all patients presenting
with OFD, OFD-like adamantinoma and adamantinoma between 1973 and
2012 was undertaken. Complete data were available for 73 patients
(42 with OFD; ten with an OFD-like adamantinoma and 21 with an adamantinoma).
The mean follow-up was 10.3 years (3 to 25) for OFD, 9.2 years (3.0
to 26.3) for OFD-like and 11.6 years (0.25 to 33) for adamantinoma.Aims
Patients and Methods
Due to the complex anatomy of the pelvis, limb-sparing resections
of pelvic tumours achieving adequate surgical margins, can often
be difficult. The advent of computer navigation has improved the
precision of resection of these lesions, though there is little
evidence comparing resection with or without the assistance of navigation. Our aim was to evaluate the efficacy of navigation-assisted surgery
for the resection of pelvic bone tumours involving the posterior
ilium and sacrum. Using our prospectively updated institutional database, we conducted
a retrospective case control study of 21 patients who underwent
resection of the posterior ilium and sacrum, for the treatment of
a primary sarcoma of bone, between 1987 and 2015. The resection
was performed with the assistance of navigation in nine patients
and without navigation in 12. We assessed the accuracy of navigation-assisted
surgery, as defined by the surgical margin and how this affects
the rate of local recurrence, the disease-free survival and the
effects on peri-and post-operative morbidity. Aims
Patients and Methods
Myxofibrosarcomas (MFSs) are malignant soft-tissue sarcomas characteristically
presenting as painless slowly growing masses in the extremities.
Locally infiltrative growth means that the risk of local recurrence
is high. We reviewed our experience to make recommendations about
resection strategies and the role of the multidisciplinary team
in the management of these tumours. Patients with a primary or recurrent MFS who were treated surgically
in our unit between 1997 and 2012 were included in the study. Clinical
records and imaging were reviewed. A total of 50 patients with a
median age of 68.4 years (interquartile range 61.6 to 81.8) were
included. There were 35 men; 49 underwent surgery in our unit.Aims
Patients and Methods
Osteosarcoma of the pelvis is a particularly difficult tumour
to treat as it often presents late, may be of considerable size
and/or associated with metastases when it presents, and is frequently
chondroid in origin and resistant to chemotherapy. The aim of this study was to review our experience of managing
this group of patients and to identify features predictive of a
poor outcome. Between 1983 and 2014, 121 patients, (74 females and 47 males)
were treated at a single hospital: 74 (61.2%) patients had a primary
osteosarcoma and 47 (38.8%) had an osteosarcoma which was secondary
either to Paget’s disease (22; 18.2%) or to previous pelvic irradiation
(25; 20.7%). The mean age of those with a primary osteosarcoma was 29.3 years
(nine to 76) and their mean follow-up 2.9 years (0 to 29). The mean
age of those with a secondary sarcoma was 61.9 years (15 to 85)
and their mean follow-up was one year (0 to 14). A total of 22 patients with a primary sarcoma (52.4%) and 20
of those with a secondary sarcoma (47.6%) had metastases at the
time of presentation. Aims
Patients and 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
Clinical studies of patients with bone sarcomas have been challenged
by insufficient numbers at individual centres to draw valid conclusions.
Our objective was to assess the feasibility of conducting a definitive
multi-centre randomised controlled trial (RCT) to determine whether
a five-day regimen of post-operative antibiotics, in comparison
to a
24-hour regimen, decreases surgical site infections in patients
undergoing endoprosthetic reconstruction for lower extremity primary
bone tumours. We performed a pilot international multi-centre RCT. We used
central randomisation to conceal treatment allocation and sham antibiotics
to blind participants, surgeons, and data collectors. We determined
feasibility by measuring patient enrolment, completeness of follow-up,
and protocol deviations for the antibiotic regimens. Objective
