IntroductionEndoprosthetic reconstruction is a widely used technique; however, it is associated with various postoperative complications. One often overlooked complication is the alteration of foot loading patterns. This pilot study evaluated functional outcomes with postoperative static foot loading patterns in patients undergoing endoprosthesis replacements compared to the contralateral limb.

Methods: With representation from Europe (43%; n = 133), North America (17%; n = 53), South America (16%; n = 49), Asia (13%; n = 40), Australasia (5%; n = 16), the Middle East (4%; n = 12), and Africa (2%; n = 6), the combined experience of treating bone sarcomas among attendees totalled approximately 30,000 cases annually, equivalent to 66 years of experience in the UK alone. The meeting's process began with the formation of a local organizing committee, regional leads, and a scientific committee comprising representatives from 150 specialist units across 47 countries.

Bipolar hip endoprosthesis replacement is a commonly employed procedure in orthopaedic oncology that requires the resection and reconstruction of the proximal femur. With improving survival rates, issues of implant durability and acetabular wear have become increasingly important. The decision to replace the acetabulum in bipolar hip endoprosthesis replacement procedures remains a topic of debate.

Introduction: The foot is a complex structure composed of several tissues, each of which can be the origin of the proliferation and development of the tumour. Most lesions about the foot are reactive or inflammatory, but some are true neoplasms.
Method: This is a retrospective analysis of 4997 patient records treated in the Orthopaedic Oncology Unit of University Malaya Medical Centre, Malaysia, between 1 January 2010 to 31 December 2020.
Background: Clavicle fractures are traditionally treated non-operatively. This study determines the functional outcome of midshaft clavicle fractures treated non-operatively, the factors influencing it, and the incidence of acromioclavicular joint (ACJ) arthrosis.
Methods: Patients with midshaft clavicular fractures treated non-operatively between 16 and 50 years old with no prior AC joint problems were assessed.
Background: Ulna styloid fracture occurs approximately about 55% of all distal end of radius fractures. However, the clinical and functional outcome of these fractures remains indefinite.
Results: Only 56 patients with distal radius fractures had concomitant ulna styloid fractures.
The main role of the host immune system is to identify and eliminate cancer cells, which is a complex process, but it is not a fail-safe mechanism. Many sarcoma patients succumb to this disease despite treatments rendered. The aim of this pilot study was to compare the levels of CD4+ T-cells, T-regulatory (Treg) cells, and cytokines such as tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), interleukin-17A (IL-17A), and transforming growth factor-beta-1 (TGF-β1) in peripheral blood leukocytes of sarcoma patients and healthy controls.

Introduction: There is no consensus regarding the reconstruction method for type 1 resections around the pelvis. Various methods are currently used, such as resection without reconstruction, bone graft (autologous, recycled, allograft) with simple fixation, and pedicle screw-rod fixation with or without bone grafting. We aim to study the outcome of pedicle screw-rod reconstruction without bone grafting in type 1 pelvic resections involving sacroiliac joint to show that pedicle screw-rod construct alone is stable and has low risk of failure.

Background: This study aimed to determine the prevalence and risk factors of anxiety and depression among orthopaedic oncology patients, their quality of life and coping strategies.
Methods: This cross-sectional study recruited patients from the outpatient orthopaedic oncology clinic at a tertiary institution. Data were collected from self-report questionnaires: Hospital Anxiety and Depression Scale Hospital Anxiety Depression Scale, World Health Organization Quality of Life (WHOQOL-BREF) and Brief Coping with Problems Experienced (Brief COPE).

Purpose: Bone tumours are increasingly treated with limb-salvage surgeries. However, implant infection is a devastating complication, greatly affecting the functional outcome. Yet, data on functional outcome post-implant infection are scarce.

For Campanacci grade II and III lesions of the distal radius and in cases of recurrence, we usually carry out wide resection and reconstruction. There are numerous publications on the treatment of GCT of the distal radius.

Giant cell tumour of the bone (GCTB) has been classically treated surgically. With the advent of denosumab, there is potential to use it as a targeted therapy to downstage the tumour and control its progression. Like all new therapies, the dosage, duration, and long-term effects of treatment can only be determined over the time through numerous trials and errors.

The natural course of compensation leads to biomechanical alteration in human musculoskeletal system leading to adverse effects. General consensus accepts LLD more than 2 cm as significant to cause biomechanical alteration.

Giant cell tumor (GCT) of the bone is a benign, locally aggressive neoplasm that has a high tendency for local recurrence. It usually has a higher incidence in the third decade of life. This is a retrospective review of a case with histologic confirmation of GCT in a skeletally immature patient involving the metatarsal bone, which is a rare site.

In this study, we evaluated the effectiveness of periodic intraoperative text messages regarding the status of ongoing surgery in reducing anxiety levels among the patients' family members.
Materials And Methods: Family members of 60 patients (one for each patient) who were undergoing major oncological surgery lasting more than 1 h were recruited and randomized into two groups (30 patients each).

Purpose: Inflammation plays a major role in tumour development, progression and metastasis. Multiple inflammatory markers such as absolute lymphocyte count, neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR) and platelet-lymphocyte ratio have been discovered as prognostic markers for various malignancies. We investigate preoperative lymphocyte count and other cell count ratios and their relation to survival and prognosis of sarcoma patients after surgery.
