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
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. We included 32 patients with

Aims. Intra-articular (IA) tumours around the knee are treated with extra-articular (EA) resection, which is associated with poor functional outcomes. We aim to evaluate the accuracy of MRI in predicting IA involvement around the knee. Methods. We identified 63 cases of high-grade sarcomas in or around the distal femur that underwent an EA resection from a prospectively maintained database (January 1996 to April 2020). Suspicion of IA disease was noted in 52 cases, six had IA
Aims. Giant cell tumour of bone (GCTB) is a locally aggressive lesion that is difficult to treat as salvaging the joint can be associated with a high rate of local recurrence (LR). We evaluated the risk factors for tumour relapse after treatment of a GCTB of the limbs. Methods. A total of 354 consecutive patients with a GCTB underwent joint salvage by curettage and reconstruction with bone graft and/or cement or en bloc resection. Patient, tumour, and treatment factors were analyzed for their impact on LR. Patients treated with denosumab were excluded. Results. There were 53 LRs (15%) at a mean 30.5 months (5 to 116). LR was higher after curettage (18.4%) than after resection (4.6%; p = 0.008). Neither

Aims. This study aimed to compare mortality in trochanteric AO/OTA A1 and A2 fractures treated with an intramedullary nail (IMN) or sliding hip screw (SHS). The primary endpoint was 30-day mortality, with secondary endpoints at 0 to 1, 2 to 7, 8 to 30, 90, and 365 days. Methods. We analyzed data from 26,393 patients with trochanteric AO/OTA A1 and A2 fractures treated with IMNs (n = 9,095) or SHSs (n = 17,298) in the Norwegian Hip Fracture Register (January 2008 to December 2020).

The aim of this study was to investigate the rate of revision for distal femoral arthroplasty (DFA) performed as a primary procedure for native knee fractures using data from the Australian Orthopaedic Association National Joint Arthroplasty Registry (AOANJRR). Methods. Data from the AOANJRR were obtained for DFA performed as primary procedures for native knee fractures from 1 September 1999 to 31 December 2020.
