Background Bone tumours of the talus are a rare cause of ankle pain. This study aims to provide additional clinical clarity regarding the presentation and management of a minimally researched topic. Methods Sixteen patients were diagnosed with bone tumour of the talus between 2002 and 2020 following referral for ankle pain.

Bone biopsy results in patients with a history of malignancy: a case series of 378 patients.

Objective: The value of a bone biopsy in patients who present with a bone lesion and past medical history of malignancy is uncertain. The objective of this study was to evaluate the outcome of bone biopsies in patients with a history of a malignancy undergoing bone biopsy of a lesion in a regional bone tumour unit. Secondary outcomes include the assessment of survival in the different outcome groups.

Prediction of pathological fracture in patients with metastatic disease of the lower limb.

The aim of this study was to investigate if the risk of pathological fracture can be predicted with the proportion of body weight that can be put through the affected leg in patients with metastatic bone disease of the lower limb. A prospective observational study was conducted in patients with metastatic disease in the lower limb. Receiver Operator Characteristic curves were used to identify the optimum threshold level of single stance weight bearing to predict fracture and compared to the Mirels score.

Prognostic indicators of outcome for patients with skeletal metastases from carcinoma of the prostate.

Aims: The purpose of this study was to identify prognostic indicators of outcome at presentation to the orthopaedic surgeon, in patients with metastatic prostate cancer. Our aim was to use this information in a pragmatic, clinic-based approach so that surgical decision making could be optimized to benefit the patient in their remaining lifetime.

Patients And Methods: A cohort analysis was undertaken of all patients with metastatic disease of the prostate who presented to a regional orthopaedic centre in the United Kingdom between 2003 and 2016.

The validity of the Mirels score for predicting impending pathological fractures of the lower limb.

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.

Hemiarthroplasty proximal femoral endoprostheses following tumour reconstruction: is acetabular replacement necessary?

Aims: Dislocation rates are reportedly lower in patients requiring proximal femoral hemiarthroplasty than for patients undergoing hip arthroplasty for neoplasia. Without acetabular replacement, pain due to acetabular wear necessitating revision surgery has been described. We aimed to determine whether wear of the native acetabulum following hemiarthroplasty necessitates revision surgery with secondary replacement of the acetabulum after proximal femoral replacement (PFR) for tumour reconstruction.

Complete resolution and remodeling of chronic recurrent multifocal osteomyelitis on MRI and radiographs.

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare condition thought to be under-diagnosed, with a true prevalence of more than the 1 in 10,000 estimated. It is a condition that is classically described as polyostotic with a relapsing and remitting course, preferentially affecting the metaphyses of tubular bones in the pediatric population. Lesions have characteristic appearances of cortical hyperostosis and mixed lytic/sclerotic medullary appearances radiographically, with active osteitis and periostitis best seen with fluid-sensitive sequences on magnetic resonance imaging (MRI).

The impact and efficacy of surveillance in patients with sarcoma of the extremities.

Objectives: In this cross sectional study, the impact and the efficacy of a surveillance programme for sarcomas of the extremities was analysed.

Methods: 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.

Results: Of the 909 patients who had a review appointment in 2014, 131 were under review for a high-grade sarcoma of the extremities following treatment with curative intent.

Osteobastoma of the Talus: A case report and review of the literature.

Osteoblastoma is benign bone forming tumour with rare malignant transformation. The common locations include spine, proximal humerus and hip. It rarely affects the talus.

Surveillance of intramedullary cartilage tumours in long bones.

Aims: The purpose of this study was to determine if clinical and radiological surveillance of cartilage tumours with low biological activity is appropriate.

Patients And Methods: A total of 98 patients with an intramedullary cartilage neoplasm in a long bone met our inclusion criteria and were included in the study. These patients had undergone a total of 384 scans.

Unusual lesions mimicking impingement syndrome in the shoulder joint - Think medially.

Impingement syndrome is usually caused by irritation of the rotator cuff within the sub acromial space and this includes the coraco-acromial arch (Acromion and Coraco-acromial ligament), the acromio-clavicular joint and occasionally the coracoid. Iatrogenic causes such as sutures, pins, plates or wires left from previous surgery can cause similar symptoms. We present a series of four cases mimicking "classical" impingement symptoms/signs in which the causal pathology was identified outside the sub-acromial space.

Patient factors affecting the Toronto extremity salvage score following limb salvage surgery for bone and soft tissue tumors.

Background And Objectives: The Toronto extremity salvage score (TESS) assesses physical function following limb salvage for bone and soft tissue sarcoma. In 2012, Clayer et al. showed increasing age affects the TESS score in normal individuals.

Prognostic factors for patients with skeletal metastases from carcinoma of the breast.

Aims: Surgical intervention in patients with bone metastases from breast cancer is dependent on the estimated survival of the patient. The purpose of this paper was to identify factors that would predict survival so that specific decisions could be made in terms of surgical (or non-surgical) management.

Methods: The records of 113 consecutive patients (112 women) with metastatic breast cancer were analysed for clinical, radiological, serological and surgical outcomes.

Whole-body magnetic resonance imaging in myxoid liposarcoma: A useful adjunct for the detection of extra-pulmonary metastatic disease.

Myxoid liposarcomas (MLS) are a subgroup of soft-tissue sarcomas which have a propensity for extra-pulmonary metastases. Conventional radiological staging of soft-tissue sarcomas consists of chest radiographs (CXR) and thoracic computed tomography (CT) for possible chest metastases, supplemented by magnetic resonance imaging (MRI) for local disease. The optimal radiological modality to detect extra-pulmonary metastases for systemic staging has not been proven.

Radiofrequency thermo-ablation of PVNS in the knee: initial results.

Introduction: Pigmented villonodular synovitis (PVNS) is normally treated by arthroscopic or open surgical excision. We present our initial experience with radiofrequency thermo-ablation (RF ablation) of PVNS located in an inaccessible location in the knee.

Materials: Review of all patients with histologically proven PVNS treated with RF ablation and with at least 2-year follow-up.

Subcutaneous and lung metastases from chondrosarcoma of the thumb.

We present a rare case of metacarpal chondrosarcoma with cutaneous metastases in the ipsilateral upper arm. Chondrosarcomas of the small bones of the hand rarely metastasise unlike chondrosarcomas elsewhere in the body. Excision/ray amputation rather than curettage may be preferable in the treatment of high-grade chondrosarcomas in the hand.

Accuracy of magnetic resonance imaging in planning the osseous resection margins of bony tumours in the proximal femur: based on coronal T1-weighted versus STIR images.

Objective: Assessment of the extent of tumours using magnetic resonance imaging (MRI) is the basis for bone resection in limb-salvage surgery. We aimed to compare the accuracy of T1-weighted MRI and STIR sequences in measuring the extent of proximal femoral tumours, using the macroscopic specimens as the gold standard for comparison.

Materials And Methods: We compared single coronal T1-weighted with STIR sequences in 34 proximal femoral tumours, using bivalved resected macroscopic tumours for comparison.

Image guided radiofrequency thermo-ablation therapy of chondroblastomas: should it replace surgery?

Objective: To assess the safety and effectiveness of image-guided radiofrequency ablation (RF ablation) in the treatment of chondroblastomas as an alternative to surgery.

Materials And Methods: Twelve patients with histologically proven chondroblastoma at our institution from 2003 to date. We reviewed the indications, recurrences and complications in patients who underwent RF ablation.

Diffuse pigmented villonodular synovitis (diffuse-type giant cell tumour) of the foot and ankle.

Pigmented villonodular synovitis (PVNS) is a rare benign disease of the synovium of joints and tendon sheaths, which may be locally aggressive. We present 18 patients with diffuse-type PVNS of the foot and ankle followed for a mean of 5.1 years (2 to 11.
