Aims. The aim of this study was to validate the Mirels score in predicting
pathological fractures in metastatic disease of the lower limb. Patients and Methods. A total of 62 patients with confirmed metastatic disease met
the inclusion criteria. Of the 62 patients, 32 were female and 30
were male. The mean age of patients was 65 years (35 to 89). The
primary malignancy originated from the breast in 27 (44%) patients,
prostate in 15 (24%) patients, kidney in seven (11%), and lung in
four (6%) of patients. One patient (2%) had metastatic carcinoma
from the lacrimal gland, two patients (3%) had multiple myeloma,
one patient (2%) had lymphoma of bone, and five patients (8%) had
metastatic carcinoma of unknown primary. Plain radiographs at the
time of initial presentation were scored using Mirels system by
the four authors. The radiographic components of the score (anatomical
site, size, and radiographic appearance) were scored two weeks apart.
Inter- and intraobserver reliability were calculated with Fleiss’
kappa test. Bland-Altman plots were created to compare the variances
of the individual components of the score and the total Mirels score. Results. Kappa values for the interobserver variability of the components
of the Mirels score were k = 0.554 (95% CI 0.483 to 0.626) for site,
k = 0.342 (95% CI 0.285 to 0.400) for size, k = 0.443 (95% CI 0.387
to 0.499) for radiographic appearance, and k = 0.294 (95% CI 0.258
to 0.331)for the total score. Kappa values for the intra-observer
reliability were k = 0.608 (95% CI 0.506 to 0.710) for site, k = 0.579
(95% CI 0.487 to 0.670) for size, k = 0.614 (95% CI 0.522 to 0.703)
for radiographic appearance, and k = 0.323 (95% CI 0.266 to 0.379)
for total score. Conclusion. Our study showed fair to moderate agreement between authors when
using the Mirels score, and moderate to substantial agreement when
authors rescored radiographs. The Mirels score is subjective and
lacks reproducibility in predicting the risk of

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

Bone loss secondary to primary or metastatic lesions of the proximal humerus remains a challenging surgical problem. Options include preservation of the joint with stabilisation using internal fixation or resection of the tumour with prosthetic replacement. Resection of the proximal humerus often includes the greater tuberosity and adjacent diaphysis, which may result in poor function secondary to loss of the rotator cuff and/or deltoid function. Preservation of the joint with internal fixation may reduce the time in hospital and peri-operative morbidity compared with joint replacement, and result in a better functional outcome.

A number of risk factors based upon mostly retrospective surgical data, have been formulated in order to identify impending pathological fractures of the femur from low-risk metastases. We have followed up patients taking part in a randomised trial of radiotherapy, prospectively, in order to determine if these factors were effective in predicting fractures. In 102 patients with 110 femoral lesions, 14 fractures occurred during follow-up. The risk factors studied were increasing pain, the size of the lesion, radiographic appearance, localisation, transverse/axial/circumferential involvement of the cortex and the scoring system of Mirels. Only axial cortical involvement >
30 mm (p = 0.01), and circumferential cortical involvement >
50% (p = 0.03) were predictive of fracture. Mirels’ scoring system was insufficiently specific to predict a fracture (p = 0.36). Our results indicate that most conventional risk factors overestimate the actual occurrence of pathological fractures of the femur. The risk factor of axial cortical involvement provides a simple, objective tool in order to decide which treatment is appropriate.
We reviewed ten patients with metastatic carcinoma and impending

The purpose of this study was to assess whether
the use of a joint-sparing technique such as curettage and grafting was
successful in eradicating giant cell tumours of the proximal femur,
or whether an alternative strategy was more appropriate. Between 1974 and 2012, 24 patients with a giant cell tumour of
the proximal femur were treated primarily at our hospital. Treatment
was either joint sparing or joint replacing. Joint-sparing treatment
was undertaken in ten patients by curettage with or without adjunctive
bone graft. Joint replacement was by total hip replacement in nine patients
and endoprosthetic replacement in five. All 11 patients who presented

The early mortality in patients with hip fractures from bony metastases is unknown. The objectives of this study were to quantify 30- and 90-day mortality in patients with proximal femoral metastases, and to create a mortality prediction tool based on biomarkers associated with early death. This was a retrospective cohort study of consecutive patients referred to the orthopaedic department at a UK trauma centre with a proximal femoral metastasis (PFM) over a seven-year period (2010 to 2016). The study group were compared to a matched control group of non-metastatic hip fractures. Minimum follow-up was one year.Aims
