Low-energy fractures complications are a major public health issue that make osteoporosis even worse. In sub-Saharan Africa, the prevalence of osteoporosis varies from 18.2% to 65.8%. There was no change in bone mineral density between HIV-infected and non-HIV-infected women in Sub-Saharan Africa, where HIV is widespread. Other investigations that demonstrated that HIV-infected people had poor BMD both before and after starting anti-retroviral treatment did not consistently show a low BMD finding. Inflammation-mediated bone remodelling has been associated with low BMD in HIV-infected patients. Antiretroviral Therapy has been demonstrated to exacerbate bone loss in addition to the pre-existing intrinsic risk of developing osteoporosis. Question: Is there loss of bone in HIV-infected patients before initiating ART? The patients who were HIV-positive and enrolled in the ADVANCE research were retrospectively reviewed on a desk. All of the 1053 individuals in the ADVANCE research had a DXA scan performed to evaluate BMD as part of the initial screening and recruitment approach. The ADVANCE research enrolled HIV-positive people and randomly assigned them to three ART arms. A total of 400 patients were reviewed. Of these 400 records reviewed, 62.3% were female. 80% of the participants were younger than 40 years old, and 3% were older than 50 years. 82% were virally suppressed with less than 50 viral copies. The prevalence of osteopenia was 25.5% and osteoporosis was 2.8%, observed in predominantly African female participants aged between 30 and 39 years. The findings of this study confirm that there is pre-existing bone loss among HIV-infected ART naïve individuals. Approximately 28.3% in our study had clinically confirmed evidence of bone loss and of these, 2.8% of the entire cohort had osteoporosis. Bone loss was most prevalent in black females who are virologically suppressed.
Orthopaedic surgeons frequently assess fragility fractures (FF), however osteoporosis (OP) is often managed by primary care physicians (PCP). Up to 48% of FF patients have had a previous fracture (Kanis et al., 2004). Discontinuity between fracture care and OP management is a missed opportunity to reduce repeat fractures. This studied aimed to evaluate current OP management in FF patients presenting to cast clinic. A single centre, prospective observational study where seven traumatologists screened for FF in cast clinic. FF was defined as a hip, distal radius (DR), proximal humerus (PH), or ankle fracture due to a ground level fall. Patients completed a self-administered questionnaire for demographics, fracture type and treatment, medical and fracture history, and previous OP care. The primary outcome was number of FF patients who received OP investigation and/or treatment. Secondary outcomes included Fracture Risk Assessment Tool (FRAX), repeat fracture rate, and anti-resorptive related fractures. Descriptive statistics were used for analysis. Between November 17, 2014 and October 13, 2015, a total of 1,677 patients attended cast clinic for an initial assessment. FF were identified in 120 patients (7.2%). The FF cohort had a mean age of 65.3 (± 14.3) years, mean BMI of 26.1 (± 5.3), and was comprised of 83.3% females. Fracture distribution was 69 (57.5%) DR, 23 (19%) ankle, 20 (16.5%) PH, and seven (5.8%) hip fractures, with 24 of the FF (19.8%) treated operatively. Thirteen (10.8%) were current smokers and 40 (33.3%) formerly smoked. A history of steroid use was present in 13 patients (10.8%). Ninety (n = 117; 76.9%) of patients ambulated independently. Twenty-two patients (18.3%) reported prior diagnosis of OP, most often by a PCP (n = 19; 73.7%) over 5 years previously. Calcium (n = 59; 49.2%) and Vitamin D (n = 70; 58.3%) were common and 26 patients (21.5%) had a prior anti-resorptive therapy, with Alendronate (n = 9) being most common. One patient had an anti-resorptive-related fracture. Raloxifene was used in ten patients. Forty-seven patients (39.2%) had a prior fracture at a mean age of 61.3 (± 11.9) years, with DR and PH fractures being most common. Eleven patients had two or more prior fractures. A family history of OP was found in 34 patients (28.1%). Mean FRAX score was 20.8% (± 10.8%) 10-year major fracture risk and 5.9% (± 6.6%) 10-year hip fracture risk (n = 30 bone densiometry within one-year). Of the 26 patients with a Moderate (10–20%) or High (> 20%) 10-year major fracture risk, only eight (30.8%) reported a diagnosis of OP and only three (11.5%) had seen an OP specialist. Cast clinics provide an opportunity for OP screening, initiation of treatment, and patient education. This cohort demonstrated a high rate of repeat fractures and poor patient reporting of prior OP diagnosis. This study likely underestimated FF and calls for resource allocation for quantifying true burden of disease and outpatient fracture liaison service.
An osteoporosis screening service for patients presenting to the fracture clinic in Derriford Hospital Plymouth was established in February 2009. We report on the findings of the first year of patients referred for dual energy X-ray absorptiometry (DEXA) screening. Patients between 50 and 75 years of age, who sustained a fracture as a result of a fall from standing height or less, who had not previously had a DEXA scan within the last two years, were referred. Patients outside these age limits with other risk factors for osteoporosis were scanned at the discretion of the fracture clinic consultant. Of those patients who were referred, 96% subsequently attended for a scan timed to coincide with their scheduled fracture clinic follow-up appointment. 402 patients were scanned in total, of which 351 were female and 51 were male. The mean patient age was 65. The results for women were as follows: 21% normal, 45% osteopenic, 34% osteoporotic. The results for men were: 19% normal, 43% osteopenic, 38% osteoporotic. The scan results were forwarded to the patient's general practitioner for action as deemed necessary. These findings support the establishment of this screening service for both men and women.
To describe the implication of Family Physicians (FPs) in the management of osteoporosis revealed by a fragility fracture. The impact and costs of fractures is straining the health system. A better collaboration between specialists and FPs should improve the evaluation and treatment of affected patients. Since January 2007, the OPTIMUS initiative is an attempt to reach that objective in the Estrie area of the Province of Quc. With OPTIMUS, rates of appropriate treatment of osteoporosis at one year in previously untreated patients more than double (53% vs 20%). In OPTIMUS, FPs remain responsible for investigation and treatment of their patients after identification of a bone fragility fracture. A coordinator based in orthopaedists outpatient clinics identifies fragility fractures in patients older than 50 y.o., informs them about bone fragility and its link to osteoporosis, and spurs them to contact their FPs to get treated; the importance of persistence on treatment is reinforced during phone follow ups. Initially and when patients remain untreated upon follow up, the coordinator sends a letter to the patients FP about the occurrence of the fracture, its predictive value for future fractures, and the need for investigation and treatment. This represents a personalized form of continuous medical education for FPs, in the hope that FPs become leaders in the prevention of fragility fractures. To evaluate the perception of FPs about OPTIMUS, we performed a mail survey targeting FPs reached at least once by OPTIMUS.Purpose
Method
Internal fixation for supracondylar fracture of the femur after total knee arthroplasty (TKA) is technically difficult and troublesome because the distal bony fragment is often osteoporotic and too small to fix by screws or K-wires. In addition, the femoral component interferes with the screws or K-wires to be inserted from distal direction for fixation of the fracture. Four knees in 4 patients (all female; average age, 81.5 +/− 2.6 years) with the fracture after TKA were treated with revision TKA. Follow-up period was between six months and 3 years postoperatively All operations were performed with the patient in the supine position and using a curved anterior (Payer) approach with or without osteotomy of the tuberositas tibiae. The femoral component was removed with detachment from fractured bony fragments. New femoral component with long stem for fixation of the fracture were inserted with bone cement in each case.Patients and Methods
Operative technique
In Alberta there are over 2,700 hip fractures per year costing the health system over $24 million in acute care costs alone. 50% of hip fracture patients have had a prior fragility fracture as a result of underlying osteoporosis (OP) that has never been assessed or appropriately treated. The Fracture Liaison Service (FLS) in Alberta aims to improve appropriate osteoporosis care, highlight and address gaps within seniors care through OP management, and provide a geriatric syndrome triage service. The FLS has developed a linkage with the Emergency Department (ED) geriatric team whereby hip fracture patients are identified in ED using a screening tool for geriatric syndromes prior to their surgery, allowing the FLS to follow through on comorbidities likely contributing to falls. An inpatient orthopaedic unit with a dedicated Registered Nurse (RN) and a Care of the Elderly Physician see and assess hip fracture patients after surgery for appropriate osteoporosis management and treatment. Screening tools have been developed to quickly detect underlying dementia and to quantify frailty to determine life expectancy and appropriate osteoporosis therapy. Patients are also referred to Geriatric Assessment Units and fall prevention programs. Patients are then contacted in the community at 3, 6,9,12 months by the FLS RN to follow up on osteoporosis therapy, and arrange other needed tests (i.e. bone mineral density, vitamin D) as needed. Information is sent to their family physician with all results. Prior to the patient's discharge from the FLS at one year, a final hand-over letter from the program will be provided outlining the plan of care for the patient. The FLS launched in June 2015 at the Misericordia hospital in Edmonton, Alberta (with plans to expand provincially). Currently 3 out of 4 hip fracture patients per week are being identified in the ED. Ninety-eight hip fracture patients have been identified post-surgery, with 71 patients eligible for enrollment in the program (five deceased patients). Sixty-six (50%) of those enrolled were discharged on osteoporosis medication compared to 8% prior to the program initiation. Seventeen (26%) of those were new medication starts. Of those not started, 7(11%) was patient choice. 11(31%) will be reassessed at 3 months for appropriate therapy. Nineteen (27%) of patients were referred to other inpatient or outpatient programs (i.e. falls, memory). Three month follow up calls have begun with patients for further data collection and a full 1 year qualitative and quantitative evaluation will be done. The implementation of an FLS with dedicated personnel to proactively manage and treat patients with appropriate investigations and interventions can close the care gap that exists in OP care. It also addresses gaps in senior care and provides appropriate referral to community geriatric programs, to improve quality of life and prevent future fractures.
Fragility fractures associated with osteoporosis (OP) reduce quality of life, increase risk for subsequent fractures, and are a major economic burden. In 2010,
Recent clinical data suggest improvement in the fixation of tibia trays for total knee arthroplasty when the trays are additive manufactured with highly
Disorders of bone integrity carry a high global disease burden, frequently requiring intervention, but there is a paucity of methods capable of noninvasive real-time assessment. Here we show that miniaturized handheld near-infrared spectroscopy (NIRS) scans, operated via a smartphone, can assess structural human bone properties in under three seconds. A hand-held NIR spectrometer was used to scan bone samples from 20 patients and predict: bone volume fraction (BV/TV); and trabecular (Tb) and cortical (Ct) thickness (Th), porosity (Po), and spacing (Sp).Aims
Methods
Surface coatings have been introduced to total joint orthopaedics over the past decades to enhance osseointegration between metal implants and bone. However, complications such as aseptic loosening and infection persist. Inadequate osseointegration remains a complication associated with implants that rely on osseointegration for proper function. This is particularly challenging with implants having relatively flat and small surface areas that have high shear loading, such as noncemented uni and total condylar knee tibial trays. Faster osseointegration can enhance recovery as a result of improved load distribution and a more stable bone-implant interface. Traditionally noncemented

Osteoarthritis (OA) is a debilitating disease characterised by degradation of articular cartilage and subchondral bone remodeling. Current therapies for early or midstage disease do not regenerate articular cartilage, or fail to integrate the repair tissue with host tissue, and therefore there is great interest in developing biological approaches to cartilage repair. We have shown previously that platelet-rich plasma (PRP) can enhance cartilage tissue formation. PRP is obtained from a patient's own blood, and is an autologous source of many growth factors and other molecules which may aid in healing. This raised the question as to whether PRP could enhance cartilage integration. We hypothesise that PRP will enhance integration of bioengineered cartilage with native cartilage. Chondrocytes were isolated from bovine metacarpal-phalangeal joints, seeded on a
Acetabular fractures, particularly in the geriatric population are on the rise. A recent study indicated a 2.4-fold increase in the incidence of acetabular fractures, with the fastest rising age group, those older than the age of 55. Controversy exists as to the role and indications for total hip arthroplasty (THA), particularly in the acute setting. Three common scenarios require further evaluation and will be addressed. 1.) What is the role of THA in the acute setting for young patients (< 55 years old)? 2.) What is the role and indications for THA in the older patient population (>55 years) and what are surgical tips to address these complex issues? 3.) What are the outcomes of THA in patients with prior acetabular fractures converted to THA?. Acetabular fractures in young patients are often the result of high energy trauma and are a life changing event. In general, preservation of the native hip joint and avoidance of arthroplasty as the first line treatment should be recommended. A recent long-term outcome study of 810 acetabular fractures treated with Open Reduction and Internal Fixation (ORIF) demonstrated 79% survivorship at 20 years with need for conversion to THA as the endpoint. Risk factors for failure were older age, degree of initial fracture displacement, incongruence of the acetabular roof and femoral head cartilage lesions. In selected younger patients, certain fracture types with concomitant injuries to articular surfaces may best be treated by acute THA. In the elderly patient population, acetabular fractures are more likely the result of low energy trauma but often times result in more displacement, comminution and damage to the articular surface.
Introduction. Distal femur fracture is a critical issue in orthopedic trauma, because it is difficult to manage especially in cases with intra-articular fracture.
Introduction. Glenoid loosening, still a main complication in shoulder arthroplasty, could be related to glenohumeral orientation and conformity, cementing techniques, fixation design and periprosthetic bone quality [1,2]. While past numerical analyses were conducted to understand the relative role of these factors, so far none used realistic representations of bone microstructure, which has an impact on structural bone properties [3]. This study aims at using refined microFE models including accurate cortical bone geometry and internal porosity, to evaluate the effects of fixation design, glenohumeral conformity, and bone quality on internal bone tissue and cement stresses under physiological and pathological loads. Methods. Four cadaveric scapulae were scanned at 82µm resolution with a high resolution peripheral quantitative computer tomography (XtremeCT Scanco). Images were processed and virtually implantated with two anatomical glenoid replacements (UHMWPE Keeled and Pegged designs, Exactech). These images were converted to microFE models consisting of nearly 43 million elements, with detailed geometries of compact and trabecular bone, implant, and a thin layer of penetrating cement through the
Introduction. Various implant designs and bearing surfaces are used in TKR. The use of All Poly Tibia and poly moulded on Tibial metal base plate has been in practice since long. Recently due to the reports on wear and osteolysis in modular articulations, these components have generated significant interest. Aim. To report early medium term results in elderly (>70 years) patients. Method. Study of 130 cases done between 2005–2009. All cases were performed by the author. Inclusion Criteria:. Patients with physiological age > 70 years. Patients with low functional demand. Good bone quality. Exclusion Criteria: Inflammatory arthropathy.

Introduction. The aim of the study was to analyze the outcome of AO cannulated screws for fractures neck of femur at our institute. Methods. 412 patients (101 males/311 females) who underwent AO screws for fracture neck of femur over 5 years (2000 -2004) and followed-up for a minimum of 2 yrs formed the study population. A retrospective review of data from electronic patient record (EPR), clinical coding, clinic and GP letters was made. Age, residential placement, Garden's classification, mode of injury, associated comorbidities, pre-admission mobilisation status, allergies, addictions and anticoagulation status details were collected. Reasons for re-admissions, re-operations and comorbidities developing as a result of these interventions were critically analysed. Post-op physiotherapy, proportion of patients sustaining contra-lateral fracture NOF and its management and mortality statistics were reviewed. Results. The mean age of patients was 68 yrs (range 18-96 yrs). Mean length of stay in hospital was 12.3 days (range2- 51 days) and mean time to operate from admission was 51 hrs (median 24 hrs). Second Surgery in form of hemiarthroplasty was required in 36, DHS in 7, Implant removal in 15 and Total hip replacement in 29 patients. Non-union occurred in 25 pts (7.93%)and avascular necrosis (AVN) in 61 Pts (19.36%) and overall 2 years mortality rate was 66 pts(16%). Conclusion. AVN and Non union was high in patients with displaced fractures, patients more than 80 yrs and patients with co-morbidities like Renal Failure, Diabetes Mellitus,
