ABSTRACT

Aims Hip fractures are a significant source of morbidity and mortality, with occurrences set to increase as our population continues to age. The aim of this study is to determine the current and future incidence of hip fractures in Ireland based on predicted population growth. Methods A search was performed of the Irish Hip Fracture Database to identify all hip fracture patients, aged over 60, from 2017-2019. Data on the current population, as well as projections up to 2046, were obtained from the Central Statistics Office, so as to determine projected hip fracture incidence in the coming decades. Results The incidence of hip fractures, in the Irish population aged over 60, was an average of 389.3 per 100,000 from 2017-2019. Annual hip fracture numbers are expected to increase by at least 158.8% by 2046, assuming a stable incidence rate. Conclusion The age and gender specific incidence of hip fractures in Ireland in those over 60 has remained stable compared to previous years. However, this study projects there will be a significant increase in hip fractures in Ireland in the coming decades and there will need to be appropriate resource allocation within future healthcare budgets.

ABSTRACT

As our population ages and increasing numbers of older patients experience major trauma it is important to understand factors that influence outcomes in this patient cohort. The aim of this study is to assess the impact of frailty in older patients who experience major trauma (Injury Severity Score (ISS) greater than 15). A retrospective cohort review using the national trauma registry data (Trauma Audit and Research Network) and an institutional database was carried out on all patients aged 60 years or older with an ISS> 15 who were treated at the regional Major Trauma Centre from 2014 to 2017 following major trauma. Frailty was assessed using the modified frailty index (mFI). Outcomes assessed included mortality, complications, hospital stay, functional outcome and discharge destination. 819 patients were included in the study. The most common mechanism of injury was fall from a height less than 2m (57.4%). 412 (51.3%) patients had a low frailty score, 280 (35%) had an intermediate frailty score and 110 (14%) had high frailty score. Increased frailty was associated with increased mortality at discharge (18.7%, 14.6% and 26.4% for low, intermediate and high frailty groups) and at one year (26.2%, 35.2% and 51%, respectively). Other predictors of mortality included male sex, age >90 years and the occurrence of a serious complication. Increasing frailty was also associated with an increased risk of serious complications including unplanned intubation, infection and progressive renal failure, and discharge to a destination other than home. This is the first study that has delineated the impact of frailty in older patients who experience major trauma and provides important information for patients, their families and healthcare providers. Future studies should focus on identifying care pathways that counteract the impact of frailty in this setting.

ABSTRACT

BACKGROUND: As healthcare systems come under ever-increasing pressure to provide more care with fewer resources, emphasis is being placed on value-based systems that maximise quality and minimize cost. The aim of this study was to determine which interventions in fracture care have been demonstrated to be cost effective. METHODS: A systemic review of cost-utility studies on the management of fractures from 1976 to 2015 was carried out using a search of the Cost-Effectiveness Analysis Registry, National Health Service Economic Evaluation Database (NHS EED) and MEDLINE. RESULTS: 20 studies were included with 15 (75%) studies assessing interventions in lower limb trauma and 8 (25%) studies assessing interventions in upper limb trauma. 50% of studies used a decision tree model and 50% used collected data alongside a randomised clinical trial. Interventions which were shown to be cost effective in lower limb trauma were total hip replacement in displaced femoral neck fractures, the SHS in stable (A1 and A2) fractures and IM nailing for unstable (A3) fractures, salvage treatment for grade IIIB and IIIC open tibial fractures and operative treatment of ankle and calcaneal fractures. For systems-based strategies, there is evidence demonstrating cost effectiveness to treating hip fractures in high volume centres and to having resources in place to facilitate fractures being treated within 48 h of injury. In upper limb trauma there was evidence showing operative treatment of displaced proximal humerus fractures to be neither clinically nor cost effective. There was evidence supporting the operative treatment of non-displaced scaphoid fractures. Overall the quality of the studies was poor with only 50% (10) of studies able to make a treatment recommendation. Reasons for this included poor quality primary source data and poor reporting methodological practices. CONCLUSION: Certain aspects of fracture management have been shown to be cost effective. However, there is a paucity of evidence in this area and further research is required so that value-based interventions are chosen by healthcare providers engaged in orthopaedic trauma care.

ABSTRACT

BACKGROUND: Surgical procedures to correct larger curve magnitudes >70° in patients with adolescent idiopathic scoliosis (AIS) are still common; despite their increased complexity, limited research has assessed the effect of preoperative curve severity on outcomes. AIM: This study aimed to examine the impact of preoperative curves >70° vs. those ≤70° on perioperative, functional and financial outcomes in patients with AIS undergoing posterior spinal fusion (PSF). METHODS: Seventy seven eligible AIS patients who underwent PSF were prospectively followed-up, until return to preoperative function was reported. Preoperative curves >70° vs. ≤70° were analysed in relation to surgical duration, estimated blood loss, perioperative complications, length of hospitalisation, return to function and cost of surgical treatment per patient. RESULTS: Severe preoperative curves >70°, identified in 21 patients (27.3 %), were associated with significantly longer surgical duration (median 6.5 vs. 5 h, p = 0.001) and increased blood loss (median 1250 vs. 1000 ml, p = 0.005)-these patients were 2.1 times more likely to receive a perioperative blood product transfusion (Relative Risk 2.1, CI 1.4-2.7, p = 0.004). Curves >70° were also associated with a significantly delayed return to school/college, and an increased cost of surgical treatment (€33,730 vs. €28,620, p < 0.0001). CONCLUSION: Surgeons can expect a longer surgical duration, greater intraoperative blood loss and double the blood product transfusion risk when performing PSF procedures on AIS patients with curves greater than 70° vs. those ≤70°. Surgical correction for curves >70°, often as a result of lengthy surgical waiting lists, also incurs added expense and results in a partial delay in early functional recovery.

ABSTRACT

BACKGROUND: Posterior spinal instrumentation and fusion for correction of adolescent idiopathic scoliosis (AIS) typically requires lengthy operating time and may be associated with significant blood loss and subsequent transfusion. This study aimed to identify factors predictive of duration of surgery, intraoperative blood loss and transfusion requirements in an Irish AIS cohort. METHODS: A retrospective review of 77 consecutive patients with AIS who underwent single-stage posterior spinal instrumentation and fusion over a two-year period at two Dublin tertiary hospitals was performed. Data were collected prospectively and parameters under analysis included pre- and postoperative radiographic measurements, intraoperative blood loss, surgical duration, blood products required, laboratory blood values and perioperative complications. RESULTS: Mean preoperative primary curve Cobb angle was 62.3°; mean surgical duration was 5.6 h. The perioperative allogeneic red blood cell transfusion rate was 42.8 % with a median requirement of 1 unit. Larger curve magnitudes were positively correlated with longer fusion segments, increased operative time and greater estimated intraoperative blood loss. Preoperative Cobb angles greater than 70° [Relative Risk (RR) 4.42, p = 0.003] and estimated intraoperative blood loss greater than 1400 ml (RR 3.01, p = 0.037) were independent predictors of red blood cell transfusion risk. CONCLUSION: Larger preoperative curve magnitudes in AIS increase operative time and intraoperative blood loss; preoperative Cobb angles greater than 70(o) and intraoperative blood loss greater than 1400 ml are predictive of red blood cell transfusion requirement in this patient group.

ABSTRACT

Peri-prosthetic osteolysis and subsequent aseptic loosening is the most common reason for revising total hip replacements. Wear particles originating from the prosthetic components interact with multiple cell types in the peri-prosthetic region resulting in an inflammatory process that ultimately leads to peri-prosthetic bone loss. These cells include macrophages, osteoclasts, osteoblasts and fibroblasts. The majority of research in peri-prosthetic osteolysis has concentrated on the role played by osteoclasts and macrophages. The purpose of this review is to assess the role of the osteoblast in peri-prosthetic osteolysis. In peri-prosthetic osteolysis, wear particles may affect osteoblasts and contribute to the osteolytic process by two mechanisms. First, particles and metallic ions have been shown to inhibit the osteoblast in terms of its ability to secrete mineralised bone matrix, by reducing calcium deposition, alkaline phosphatase activity and its ability to proliferate. Secondly, particles and metallic ions have been shown to stimulate osteoblasts to produce pro inflammatory mediators in vitro. In vivo, these mediators have the potential to attract pro-inflammatory cells to the peri-prosthetic area and stimulate osteoclasts to absorb bone. Further research is needed to fully define the role of the osteoblast in peri-prosthetic osteolysis and to explore its potential role as a therapeutic target in this condition.

ABSTRACT

UNLABELLED: Osteoporosis management post fragility fracture has traditionally been deficient with up to 60-90 % of patients remaining untreated for osteoporosis in some studies. Efforts have been made to address this deficiency with some successes reported. INTRODUCTION: The aim of this study was to assess the efficacy of two different models of screening for osteoporosis in a community fracture clinic setting. METHODS: A prospective randomised clinical trial was conducted to assess the DXA scan and treatment rates in patients with fragility fractures when assessment for osteoporosis had been initiated in the fracture clinic compared with the "usual care" of assessment initiation by the participant's general practitioner. RESULTS: Sixty-six patients were enrolled in the study. Thirty-three patients each were in the control and intervention groups. The assessment rate (DXA scan rate) was significantly better in the intervention group where participants were referred for assessment from fracture clinic compared to the control group where participants were referred for assessment by their general practitioner (68 vs 36 %, respectively; p < 0.05). For patients who were assessed for osteoporosis, treatment rates were similar in both the control and intervention groups (100 vs 88 %, p > 0.05). CONCLUSION: This study demonstrates that screening for osteoporosis initiated in fracture clinic results in improved osteoporosis management compared to screening initiated in primary care. Orthopaedic surgeons and other specialists need to be more active in managing osteoporosis in patients who present with fragility fractures and should at the very least initiate assessment in the fracture clinic setting.

ABSTRACT

Neurological conditions affecting the hip pose a considerable challenge in replacement surgery since poor and imbalanced muscle tone predisposes to dislocation and loosening. Consequently, total hip replacement (THR) is rarely performed in such patients. In a systematic review of the literature concerning THR in neurological conditions, we found only 13 studies which described the outcome. We have reviewed the evidence and discussed the technical challenges of this procedure in patients with cerebral palsy, Parkinson's disease, poliomyelitis and following a cerebrovascular accident, spinal injury or development of a Charcot joint. Contrary to traditional perceptions, THR can give a good outcome in these often severely disabled patients.

ABSTRACT

Chemokines are major regulators of the inflammatory response and have been shown to play an important role in periprosthetic osteolysis. Titanium particles have previously been shown to induce IL-8 and MCP-1 secretion in osteoblasts. These chemokines result in the chemotaxis and activation of neutrophils and macrophages, respectively. Despite a resurgence in the use of cobalt-chromium-molybdenum alloys in metal-on-metal arthroplasty, cobalt and chromium ion toxicity in the periprosthetic area has been insufficiently studied. In this study we investigate the in vitro effect of cobalt ions on primary human osteoblast activity. We demonstrate that cobalt ions rapidly induce the protein secretion of IL-8 and MCP-1 in primary human osteoblasts. This elevated chemokine secretion is preceded by an increase in the transcription of the corresponding chemokine gene. Using a Transwell migration chemotaxis assay we also demonstrate that the chemokines secreted are capable of inducing neutrophil and macrophage migration. Furthermore, cobalt ions significantly inhibit osteoblast function as demonstrated by reduced alkaline phosphatase activity and calcium deposition. In aggregate these data demonstrate that cobalt ions can activate transcription of the chemokine genes IL-8 and MCP-1 in primary human osteoblasts. Cobalt ions are not benign and may play an important role in the pathogenesis of osteolysis by suppressing osteoblast function and stimulating the production and secretion of chemokines that attract inflammatory and osteoclastic cells to the periprosthetic area.

ABSTRACT

BACKGROUND: Basic competency in musculoskeletal medicine is essential for many specialties being particularly relevant to primary care. AIM: The purpose of this study was to objectively assess the adequacy of musculoskeletal education at multiple levels of medical training from undergraduate level to primary care. METHODS: A previously validated musculoskeletal examination was administered to 303 volunteers consisting of medical students, orthopaedic specialist registrars, general practice trainees and general practitioners. RESULTS: Forty (71%) general practitioners and 74 (71.8%) general practice trainees failed to obtain the passing score of 70. Sixty-three (87.5%) medical students who had completed an intensive 1-week long course in musculoskeletal medicine failed the examination. The pass rate improved significantly for general practitioners who had completed a postgraduate rotation in musculoskeletal medicine (47.8 vs 18.1%, P < 0.01). CONCLUSIONS: These findings suggest that training in musculoskeletal medicine is inadequate at multiple levels of medical education with reform urgently required.
