Abstract:
Objectives: To compare of functional outcomes in terms of post-operativemobility for unipolar versus bipolar un-cemented hemiarthroplasty in elderly patients withdisplaced intracapsular femoral neck fractures. Study Design: Randomized Control Trial.Setting: Department of Orthopedics Bahawal Victoria Hospital, Bahawalpur. Period: April 2015to October 2016. Methodology: Sample size is (calculated by taking n6 =138, confidenceinterval 95, power of study 80, P1= 33%, P2=13%) 69 in each group. Sampling technique usedwas non probability consecutive sampling. All patients who meet the inclusion criteria presentingto orthopedic unit of Nishtar Hospital Multan with fracture neck of femur were selected for study.Patients were divided into two groups randomly by lottery method and enrolled for unipolaror bipolar hemiarthroplasty. Chi-square test was used to compare outcome variable in bothgroups. A p-value < 0.05 was considered statistically significant. Effect modifiers like age andsex was controlled by stratification. Chi square test was applied to see significant difference.Results: Overall, there were 100% (n=138) patients in this study, both genders. The mean ageof the patients was 66.35±4.29 years. (Range: 60 to 80years)Mean age and SD of group A (nowalking aid) was 54.52 ± 3.10 and in group B (walking aid) 54.99 ± 3.19. Time up go score wasnoted as successful 33.3% (n=46) and 66.7% (n=92) as unsuccessful. Walking aid was notedin 65.2% (n=90) patients. Functional outcome was noted as good in 26.8% (n=37) patientsand noted as bad in 73.2% (n=101) patients. Out of 100% (n=38) patients, good outcomewas 26.3% (n=10) unipolar and 73.7% (n=28) bipolar. Out of 100% (n=100) Bad outcomewas 59% unipolar and bipolar 41%. Conclusion: Functional outcome in term of mobility isbetter in case of bipolar prosthesis as compared to unipolar. Thus in our conclusion bipolarprosthesis is preferred procedure as compared to unipolar hemiarthroplasty in treating patientswith displaced intracapsular femoral neck fracture.

Abstract:
Neck of femur fractures are a ubiquitous injury seen by orthopaedic surgeons. In the elderly, these fractures usually occur after a low energy fall, and are invariably unilateral injuries. Bilateral neck of femur fractures have been reported in patients with metabolic bone disease, after electroconvulsive therapy, and in association with stress fractures. The otherwise healthy index patient in this case report presented most unusually, with simultaneous, bilateral neck of femur fractures that were sustained during a seizure.

Abstract:
Choice of surgical tactics in femur neckfractures is the actual problem of modern traumatology and orthopedics. The analysis of results of treatment of patients with femur neck fractures is carried out. It is taped that femur neck fractures happened in the place of the formed solitary cyst. Diagnostics of cysts of a femur neck is complicated, however at their detection, performance of an osteosynthesis of a femur neck can lead to development of a nearthrosis. Selection criteria ofpatients which were established the osteosynthesis of a neck of a femur or endoprosthesis replacement of a hip joint is shown. The received clinical and statistical results demonstrate that use of these criteria promotes decrease of quantity of auditing interventions and improvement of quality of life ofpatients.

Abstract:
Femur shaft fractures are common fractures that orthopaedic surgeons come across. Such fractures frequently associate with high energy trauma (ex: Motor vehicle accident, fall from height) in young patients or a trivial fall in elderly patients. IMIL nailing is the most frequently used modality of management for shaft of femur fractures. Early definitive treatment within 24-48 hours in stable patients reduces the risk of mortality and morbidity. Fracture of femoral neck is an unusual complication while performing IMIL shaft fracture. We present a case of iatrogenic fracture neck of femur while performing IMIL for fracture shaft of femur and the technique of fixation used for the same intra-operatively. Keywords: Miss-A-Nail, Femoral neck, Fracture, Iatrogenic, Intramedullary, Nailing.

Abstract:
Femoral fractures occur commonly in dogs and cats, accounting for 45% of all long bone fractures. Femoral fractures are classified based on anatomic locational and include fractures of the proximal epiphysis, proximal physeal fractures, subcapital fractures, fractures of the femoral neck, trochanteric fractures, subtrochanteric fractures, fractures of the femoral shaft, supracondylar fractures, distal physeal fractures, unicondylar fractures, bicondylar fractures and fractures affecting the femoral trochlea. In general, femoral fractures are not amenable to treatment with external coaptation, so surgical stabilisation or a salvage procedure is required. Selection of an implant system will depend on fracture configuration and location, and requires a thorough understanding of the forces to which the implant system will be subjected. Complications associated with stabilisation may include premature physeal closure, resorption of the femoral head or neck, malunion, non-union, altered coxofemoral development, implant failure, sciatic neurapraxia, quadriceps contracture, patellar luxation and infection. The complication rate can be substantially reduced by the use of meticulous surgical technique and appropriate implant selection with the prognosis for complete functional recovery remaining good to excellent, providing that an optimal healing environment is preserved.

Abstract:
Purpose The purpose of this paper is to report a rare case of segmental neck of femur fracture (SNoFF) and highlight its quality assurance and governance implications with respect to national guidelines, care pathways and best practice tariff. Design/methodology/approach Case report of an SNoFF in a 67-year-old woman treated at a district general hospital (DGH) was used in this study. Findings SNoFF required additional implants that delayed the surgery by five days. The authors were unable to adhere to the British Orthopaedic Association standards for trauma and Scottish Inter-Collegiate Guidelines Network recommendations which indicate that all neck of femur fractures (NoFFs) be fixed within 48 h. Though the patient was discharged without any untoward event and had an uneventful recovery, this case led us to introspect and learn how best to avoid such an incident from repeating again. Research limitations/implications This case led to an overhaul of NoFF and trauma services. The local logistics was restructured to procure “Trochanteric grip plates” within 24 h to provide mandated quality of care in an effort towards improving patient experience/outcomes. Originality/value SNoFF are rare injuries and its diagnosis is either delayed or missed in at least 20 per cent of the cases on initial evaluation. The non-availability of additional implants readily on the shelf coupled with lack of a trauma bed at the tertiary centre resulted in an unacceptable delay from admission to definitive surgery. The authors recommend that all DGHs have a mechanism/emergency procurement procedure system in place to obtain the required instrumentation kits rapidly through a sharing scheme with regional hospitals or through implant vendor to avoid unacceptable delays to surgery.

Abstract:
Includes bibliographical references
Background: Dislocation is one of the most common orthopaedic complications after primary total hip arthroplasty (THA). The reported dislocation rate in elective THR is 5 - 8%. This number increases up to 22% for THA done for neck of femur fractures. Larger femoral head sizes increase the head-neck ratio and range of motion before impingement, therefore reducing the dislocation rate. Due to the reported increase in dislocation for trauma, some surgeons prefer to do a hemi-arthroplasty or open reduction and internal fixation (ORIF). Methods: A retrospective review of all THA done for neck of femur fractures during 2006 - 2012 was undertaken at a large referral hospital. Records were reviewed for patient related and surgical risk factors. We excluded all pathological fractures, extra-capsular fractures and failed ORIF. Results: A total of 96 cases were identified as suitable for analysis. Average age at surgery was 73.2 years (range 30 - 81). Delay to surgery was 5.3 days (range 1 - 63). Average follow up period was 18.3 months (range 3 months - 4.3years). Four patients (4.3%) had a confirmed dislocation. The four patients who had confirmed dislocation had the following characteristics, 28 mm femoral head size, age over 60 years, 2 posterior approaches and 3 females, although not statistically significant. Conclusion: The outcomes of THR in patients with neck of femur fractures can be favourable and provide good long-term prosthesis survival. We report on low dislocation rate post total hip replacement for intra-capsular neck of femur fractures.

Abstract:
This thesis examined the cost-effectiveness of different types of arthroplasty and fixation methods used to treat femoral neck fractures in the Australian health system. Using a decision analytic model, the study measured the costs and health outcomes associated with different treatment options to determine which prostheses led to cost-effective care. Cemented fixation of prostheses was found to be more cost-effective than uncemented fixation. The cost-effectiveness of different arthroplasties varied with age and whether QALYs or revision surgeries were the health outcome assessed. The results support recommendations that cemented prostheses be used for femoral neck fractures. Further research into defining population groups, collecting preference based values of health states and costs would be beneficial to inform further research into this area.

Abstract:
Les fractures du fémur proximal de la personne âgée sont généralement fixées par des dispositifs d'ostéosynthèse. Pour les fractures particulières dites inter-trochantériennes, il est possible de fixer la fracture de manière intra-médullaire (à l'intérieur de l'os) ou de manière extra-médullaire (en dehors de l'os). Pour chaque type de traitement, les hôpitaux sont équipés des deux systèmes de fixation. Les différences de morphologie des individus impliquent l'existence de multiples références d'implants et donc de surcoûts en termes d'équipement. Dans ce travail de thèse, un implant original adaptable à la plupart des morphologies a été développé. Cet implant permettra non seulement d'offrir aux chirurgiens une souplesse au cours des interventions chirurgicales mais aussi de réduire de manière significative les stocks d'implants dans les hôpitaux. Le comportement mécanique de l'implant est étudié dans différents cas de fractures par deux approches complémentaires, une méthode numérique par Éléments Finis et une approche expérimentale mettant en oeuvre des techniques de stéréo-corrélation à partir d'images de caméras rapides. Les résultats des calculs numériques sont confrontés à ceux issus d'essais réalisés sur des fémurs synthétiques, puis cadavériques en laboratoire d'anatomie. Les comparaisons avec des implants existants montrent que ce nouveau concept d'implant permet une fixation plus stable des fragments osseux et une bonne compression du foyer de fracture.

Abstract:
Emergency medicine trainees are required to complete an anaesthetic placement and obtain basic anaesthetic competencies. This chapter is not intended to provide the practical skills for delivering an anaesthetic. Instead, this chapter focuses on the theory of managing and predicting a difficult airway in the emergency department, which is more likely to appear in the short-answer (SAQ) paper. It also focuses on procedural sedation which also may appear in the SAQ paper due to its growing use in the emergency department (ED). This chapter also covers pain management, for which the Royal College of Emergency Medicine (RCEM) have introduced clinical standards. In addition, this chapter covers the use of peripheral nerve blocks such as a fascia iliaca block for neck of femur fractures. Due to the growing use of peripheral nerve blocks in the ED, such detailed knowledge is required.

Abstract:
The neck portion of the human femur is the most vulnerable region to attract stress-induced fractures. The loads of the human body act on the hip joint and on the greater trochanter region through abductor muscles. The bone is a natural composite and a good example of functionally graded material (FGM). This study considers a probabilistic finite element approach to assess the critical stresses in the femur under static loads. Material properties assigned to the bone model are linearly elastic, isotropic and orthotropic. Material characterization in terms of bone density is established by Computed Tomography (CT) data. The strength reliability and safety margin are obtained using relevant limit state function. Sensitivity analysis with respect to random parameters provides basis for a possible implant material characterization.

Abstract:
Aim/Purpose: The aim of the study was to analyze the structure of the bone tissue by using texture analysis of the bone trabeculae, as visualized in a routine radiograph of the proximal femur . This could provide objective information regarding both the mineral content and the spatial structure of bone tissue. Therefore, machine-learning tools were applied to explore the use of texture analysis for obtaining information on the bone strength. Background: One in three women in the world develops osteoporosis, which weakens the bones, causes atraumatic fractures and lowers the quality of life. The damage to the bones can be minimized by early diagnosis of the disease and preventive treatment, including appropriate nutrition, bone-building exercise and medications. Osteoporosis is currently diagnosed primarily by DEXA (Dual Energy X-ray Absorptiometry), which measures the bone mineral density alone. However, bone strength is determined not only by its mineral density but also by the spatial structure of bone trabeculae. In order to obtain valuable information regarding the bone strength, the mineral content and the spatial structure of the bone tissue should be objectively assessed. Methodology: The study includes 17 radiographs of in-vitro femurs without soft tissue and 44 routine proximal femur radiographs (15 subjects with osteoporotic fractures and 29 without a fracture). The critical force required to fracture the in-vitro femurs was measured and the bones were divided into two groups: 11 solid bones with critical fracture force higher than 4.9kN and 6 fragile bones with critical fracture force lower than 4.9kN. All the radiographs included an aluminum step-wedge for calibrating the gray-levels values (See Figure 3). An algorithm was developed to automatically adjust the gray levels in order to yield equal brightness and contrast. Findings: The algorithm characterized the in-vitro bones with as fragile or solid with an accuracy of 88%. For the radiographs of the patients, the algorithm characterized the bones as osteoporotic or non-osteoporotic with an accuracy of 86%. The most prominent features for estimating the bone strength were the mean gray-level, which is related to bone density, and the smoothness, uniformity and entropy, which are related to the spatial distribution of the bone trabeculae. Impact on Society: Analysis of bone tissue structure, using machine-learning tools will provide a significant information on the bone strength, for the early diagnosis of osteoporosis. The structure analysis can be performed on routine radiographs of the proximal femur, with high accuracy. Future Research: The algorithm for automatic structure analysis of bone tissue as visualized on a routine femoral radiograph should be further trained on a larger dataset of routine radiographs in order to improve the accuracy of assessing the bone strength.

Abstract:
A proximal femur fracture due to osteoporosis is one of serious health care problems in aging societies. Osteosynthesis with pin or screw type of implants, such as Hansson pin (HP), Dual SC Screw (DSCS), is widely used for femoral neck fracture treatment in Japan. Unfortunately, some complications such as secondary fractures, especially peri-prosthetic fractures, may occur during postoperative rehabilitation period. In order to reveal the potential cause of the postoperative fracture from the viewpoint of the biomechanics, authors had already performed the dynamic stress analysis of the treated proximal femur based on finite element (FE) analysis. The final goal of our project is to establish the reliable postoperative bone fracture risk assessment method in response to the daily activity including mainly walking. The aim of this study is to propose a novel elastic multi body analysis method based on FE analysis for proximal femur biomechanics. Patient-specific 3D left hip joint FE model was constructed from an elderly female volunteer’s CT images. The model consists of the pelvis, proximal femur, cartilage and DSCS, as multi bodies. The dynamic loading and boundary conditions were applied to the model for simulating a gait motion. Direction and magnitude of the loads varies in response to the gait motion. The time dependent loading forces; hip contact, gluteus medius, gluteus maximus, tensor fasciae latae and adductor, acting around the hip joint was obtained by inverse dynamic analysis of a human gait using in-house lower-limb musculoskeletal model. These loading and boundary conditions for simulating the gait motion are the major technical advantages of the proposed multi body analysis comparing with the conventional static FE analysis. Time varying stress distribution during the gait was evaluated by using dynamic explicit method via ABAQUS. In order to visually demonstrate dynamic stress distribution, we examined the time varying von Mises stresses at the representative points located on the cortical surface of the proximal femur; femoral head, fracture surface and around the lateral insertion holes. The results indicate significant increase of the stresses around the proximal lateral insertion holes for DSCS treatment. Maximum stress values are good agreement with the previous static FE analysis, on the other hand, these biomechanical discussions based on the stress time histories are only obtained from the proposed method. It is indicated that the proposed method is feasible to support the better pre- and postoperative clinical decisions, which is the main contribution of this study.

Abstract:
There is renewed interest in resurfacing hip prostheses. While stemmed prostheses have been extensively studied in the past, little is known about the biomechanics of epiphyseal prostheses. Our aim was to develop a combined experimental-numerical tool to study the intact and operated epiphysis. Bone and implant stress, relative micromotion and failure mode in the intact and implanted bone were investigated. Twelve pairs of cadaver human femurs were studied intact, to fully characterize the proximal epiphysis. Four were then implanted with a commercial resurfacing prosthesis. They were tested in the elastic range, while strains were measured with 15 rosettes. Implant micromotions were measured in the operated condition. A total of 7 loading scenarios were simulated to cover the range of typical motor tasks. Additionally, Finite Element (FE) models were built using a validated procedure for assigning inhomogeneous material properties based on CT data. To allow extensive validation of the FE model, additional measurements were taken in vitro: bone deflection in various points, indirect measurement of load application point, digitizing of the bone surface and gauge locations. The FE models were also used to identify the most critical load scenario to recreate in vitro spontaneous head-neck fractures. Strain measurements were successfully obtained in intact and implanted femurs, providing the natural strain pattern, and indicating moderate stress-shielding in the operated condition. Results on the 6 femurs that were modeled showed that FE can predict overall displacements with an accuracy of 0.4mm, and principal stress with an accuracy of 10% (Root Mean Squared, RMSE). In vitro failure tests were successful: all specimens fractured, with a variety of failures ranging from sub-capital to trans-trochanteric. This confirms the suitability of this test model to replicate spontaneous fractures in elderly subjects. In conclusion, an experimentally validated FE method was developed, that run in parallel with an optimized in vitro simulation. These tools can successfully predict the stress distribution and the failure mode in the proximal femur both in its natural condition and with a resurfacing prosthesis.

Abstract:
Introduction: Little is known about the impact of enzyme-inducing antiseizure drugs (EI-ASD) on the reduction of Bone Mineral Density (BMD) in men with epilepsy (MWE). Objectives: To evaluate the BMD in MWE exposed to EI-ASDs (phenytoin, carbamazepine and phenobarbital) and its relationship with the duration of epilepsy. Methods: We evaluated BMD from 74 consecutive MWE (median age (range), 52.5 (25- 74) years) exposed to previous or current EI-ASDs, followed at UNICAMP-Brazil. Individuals were split into two groups (young-group, 31 individuals [25-49 years]; older group, 43 subjects, [50-74 years]). The BMD test evaluated t-score indexes from the femoral neck, whole femur and lumbar spine. Osteopenia was defined with t-score of - 1.0 to -2.4; osteoporosis, with T-scores lower than -2.5. Data were extracted from medical records. We analyzed data with SPSS22, performed chi-square tests for categorical variables and applied a partial correlation test (controlled for age) between BD scores and duration of epilepsy. Results: BMD was reduced in 49/74 men (66.2%). Both groups presented equivalent proportions of BMD abnormalities (p=0.087) (young-group [14/41 normal (45%), 12/31 osteopenia (39%), 5/31 osteoporosis (16%)]; older-group [11/43 normal (26%), 16/43 osteopenia (37%), 16/43 osteoporosis (37%)]. BMD did not correlate with the duration of disease or age of onset. Conclusion: BMD reduction is highly prevalent in MWE exposed to EI-ASD, including young individuals. Data suggest that exposure to EI-ASD may associate with early BMD reduction, which evolve to osteopenia and osteoporosis. BMD evaluation in MWE and appropriate treatment may be necessary to reduce fractures’ risk.
