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
Introduction: Estimates suggest that 50% of new cases of invasive cancer diagnosed each year will eventually metastasise to bone. The proximal end of the femur is the most common site of long bone involvement by metastatic disease. Accepted principles for the treatment of metastatic disease of the proximal femur have been published. The results of 31 consecutive patients treated with a long intramedullary hip screw for metastatic disease of the proximal femur are reported. Patients and Methods: Retrospective case note review of all patients that had a long intramedullary hip screw for metastatic disease affecting the proximal femur over a four-year period 1998–2002.

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). Exclusions were made for patients aged < 60 years,
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.
A 52 year old male presented with a pathological subtrochanteric femoral fracture secondary to multiple myeloma. While stabilising the fracture with a Long Proximal Femoral Nail (PFN) distal femur fracture occurred, while introducing the distal locking screw, which was fixed with two cables. Partial weight bearing was allowed for the first six weeks. Three months after surgery the distal static locking screw broke. Eighteen months post surgery patient developed sudden spontaneous right hip pain and was treated with further chemotherapy and radiotherapy. Radiographs showed the fracture had not healed but there was no evidence of implant failure. Two years later patient presented with sudden increase in right hip pain with inability to walk. Radiographs showed that the nail had broken at the proximal hip screw hole. At revision surgery, with difficulty the broken distal locking screws were removed and the broken nail was removed by pushing it from below through the knee. The non union was stabilised with another long PFN. At four months post revision surgery there were radiological signs of bone healing and patient had no symptoms.
This is the first reported incidence of failure of long PFN in a pathological femoral fracture stabilisation.

The presence of metastatic bone disease (MBD) often necessitates major orthopaedic surgery. Patients will enter surgical care either through emergent or electively scheduled care pathways. Patients in a pain crisis or with an acute fracture are generally admitted via emergent care pathways whereas patients with identified high-risk bone lesions are often booked for urgent yet scheduled elective procedures. The purpose of this study is to compare the post-operative outcomes of patients who present through emergent or electively scheduled care pathways in patients in a Canadian health care system. We have conducted a retrospective, multicenter cohort study of all patients presenting for surgery for MBD of the femur, humerus, tibia or pelvis in southern Alberta between 2006 and 2021. Patients were identified by a search query of all patients with a diagnosis of metastatic cancer who underwent surgery for an impending or actual

Primary bone tumors are rare, complex and highly heterogeneous. Its diagnostic and treatment are a challenge for the multidisciplinary team. Developments on tumor biomarkers, immunohistochemistry, histology, molecular, bioinformatics, and genetics are fundamental for an early diagnosis and identification of prognostic factors. The personalized medicine allows an effective patient tailored treatment. The bone biopsy is essential for diagnosis. Treatment may include systemic therapy and local therapy. Frequently, a limb salvage surgery includes wide resection and reconstruction with endoprosthesis, biological or composites. The risk for local recurrence and distant metastases depends on the primary tumor and treatment response. Cancer patients are living longer and bone metastases are increasing. Bone is the third most frequently location for distant lesions. Bone metastases are associated to pain,
Acute Haematogenous Osteomyelitis (AHO) remains a cause of severe illness among children. Contemporary research aims to identify predictors of acute and chronic complications. Trends in C-reactive protein (CRP) following treatment initiation may predict disease course.

A retrospective review of all patients <16 years with presumed AHO presenting to a tertiary referral centre between 2008–2018 was performed. Multivariate was analysis used to identify factors associated with an acute or chronic complication. An “acute” complication was defined as need for two or more surgical procedures, hospital stay longer than 14-days, or recurrence despite IV antibiotics. A “chronic” complication was defined as growth or limb length discrepancy, avascular necrosis, chronic osteomyelitis,

Paediatric bone and joint infections remain common in low- and middle-income countries (LMICs). We aimed to determine the complication rate and incidence of disseminated infection in paediatric bone and joint infections in an LMIC setting. Secondly, we aimed to elucidate factors associated with complications and disseminated disease. We retrospectively reviewed our database for children that presented with bone and joint infections between September 2015 and March 2019. Data were extracted to identify factors that were associated with development of complications and disseminated infection. We analysed 49 children. The median age at presentation was 6 years (range 1 month to 12 years). Locally advanced disease was present in 13 children (27%). The remaining 36 children were evenly divided (18/49 each, 37%) between isolated AHOM and SA, respectively. Disseminated disease was present in 16 children (33%) and was associated with locally advanced disease, an increase in number of surgeries and an increased length of stay. Twenty-six complications were documented in 22 (45%) children. Chronic osteomyelitis developed in 15/49 (31%) cases, growth arrest in 5/49 (10%), and
This study aimed to investigate the outcomes of open tibia shaft fractures at a level one trauma center in a developing world setting.

We previously reported a 15% local recurrence rate at a median follow-up of 30 months in 20 patients with high-risk GCTB treated with neoadjuvant Denosumab. The aim of this study was to determine if this initial favourable outcome following the use of Denosumab was maintained with longer follow-up. Methods. Patients with GCTB of the limb considered high-risk for unsuccessful joint salvage, due to minimal periarticular and subchondral bone, large soft tissue mass, or
Waiting time to access medical care in Canada is 20% more than the international average. Delay in instituting care in trauma patients has been shown to correlate with higher complication rates and an increase in mortality. About 11% of all fractures occur in the femur and are usually treated operatively. Delay to operative treatment is a source of distress to patients and a major factor for poor outcome. Knowledge gaps exist for statistics on operative delay to fixation of femur fractures and the influence on complications and cost of treatment. This study describes (1) the effect of delay to fixation of femur fractures on complications and on the overall cost of care in hospitals in Quebec Province of Canada; and (2) proposes a time frame within which femur fractures should be operated on to minimize the risk of complications and reduce treatment cost. 6,520 adult patients operated for closed femoral fractures between July 1993 and December 2002 were reviewed. Data was accessed from (a) the Quebec Trauma Registry, (b) the hospitalised patients’ database, Maintenance et exploitation des données pour l’étude de la clientèle hospitalière (MED-ECHO) and (c) the medical insurance claims databases, Régie de l’assurance maladie Québec (RAMQ).

The aim of this study was to investigate mortality and risk of intraoperative medical complications depending on delay to hip fracture surgery by using data from the Norwegian Hip Fracture Register (NHFR) and the Norwegian Patient Registry (NPR). Patients and Methods. A total of 83 727 hip fractures were reported to the NHFR between 2008 and 2017.
Introduction: Despite advances in radiotherapy and chemotherapy, metastatic disease of the spine remains a challenging situation for spinal surgeons. An individual therapy should be chosen to provide the maximum palliative effect (reduction of pain, restoration of stability and function) with a minimum of operative morbidity and mortality. Predicting prognosis is the key factor in selecting the proper treatment. Therefore, various assessment systems have been designed in order to provide a basis for deciding the course of treatment. Such systems have been proposed by Tokuhashi, Sioutos, Tomita, Van der Linden, and Bauer. The scores differ greatly in the kind of parameters assessed. The aim of this study was to evaluate the prognostic value of each score. Patients and Methods: Eight parameters were assessed for 69 patients (37 male, 32 female): location, general condition, number of extraspinal bone metastases, number of spinal metastases, visceral metastases, primary tumour, severity of spinal cord palsy, and
Objectives. In this prospective cohort study, we investigated whether patient-specific finite element (FE) models can identify patients at risk of a pathological femoral fracture resulting from metastatic bone disease, and compared these FE predictions with clinical assessments by experienced clinicians.

Intracapsular neck of femur fractures may be treated with fixation or arthroplasty, depending on fracture characteristics and patient factors. Two common methods of fixation are the sliding hip screw, with or without a de-rotation screw, and cannulated screws. Each has its merits, and to date there is controversy around which method is superior, with either method thought to risk avascular necrosis of the femoral head (AVN) rates in the region of 10–20%. Fixation with cannulated screws may be performed in various ways, with current paucity of evidence to show an optimum technique. There are a multitude of factors which are likely to affect patient outcomes: technique, screw configuration, fracture characteristics and patient factors. We present a retrospective case series analysis of 65 patients who underwent cannulated screw fixation of a hip fracture. Electronic operative records were searched from July 2014 until July 2019 for all patients with a neck of femur fracture fixed with cannulated screws: 68 were found.

Introduction and Objectives: Half of primary tumors tend to disseminate to bones, and metastasis to bone is the third most common localisation for disseminated disease, after the lungs and liver. It is also the most common form of neoplasia in the skeleton. Treatment of bone metastasis is essentially palliative, and in select cases improves patient survival. We present results from the last 15 years in our centre. Materials and Methods: Between the years 1988–2003, our surgical oncology unit has treated 451 patients with bone metastasis. Of these, 49% were male, and 51% were female. Average age was 64 years (19–98). The most common causes were metastatic breast cancer (34%), unknown tumours (17%), multiple myeloma (9%), prostate cancer (9%), lung cancer (7%), bladder cancer (6%), and others (18%). Tumours localised to the following locations: femur (31%), spine (27%), multiple locations (13%), pelvis (11.5%), humerus (9%), and other locations (8.5%).

The use of endoprosthesis implants is frequent for tumours involving the proximal third of the femur and not amenable to primary arthroplasty or internal fixation. In this population, these implants are preferentially cemented given poor bone quality associated with systemic diseases and treatments. Loosening is a common complication of these implants that have been linked to poor bone quality, type of implants and importantly cementing technique. Thus, these techniques vary between different surgeons and based mainly on previous experience. One of the most successful cementing techniques in the arthroplasty literature is the French paradox. This technique involves removing the cancellous bone of the proximal femoral metaphysis and selects the largest stem to tightly fit the created cavity delineated by cortical bone. Cementing the implant results in a very thin cement layer that fills the inconsistent gaps between the metal and the bone. To our knowledge, no previous report exists in the literature assessing loosening in proximal femur replacement using the French paradox cementing technique. In this study, we sought to examine (1) rates of loosening in proximal femur replacement, and (2) the oncological outcomes including tumour recurrence and implant related complications. A retrospective study of 42 patients underwent proximal femur replacement between 1990 and 2018 at our institution. Of these, 30 patients met our inclusion criteria. Two independent reviewers have evaluated the preoperative and the most recent postoperative radiographs using the International Society of Limb Salvage (ISOLS) radiographic scoring system and Gruen classification for femoral stem loosening. Additionally, the acetabulum was evaluated for erosion according to the criteria of Baker et al. The mean age of this cohort was 60.5 (19–80), with 60% being males. The primary origin was metastatic in 17 (56.7%) patients, bone sarcoma in 10 (33.3%) patients and soft tissue sarcoma in 3 (10%) patients.
Introduction: Primary bone lymphoma is a rare neoplastic disease of bone. Treatment consists predominantly of chemotherapy and radiotherapy. Surgery can be considered for large lytic lesions with impending
