Filter by:Assessment of subsidence of cementless stem following arthroplasty for fracture neck of femur.
The patients who underwent hip arthroplasty in our hospital from January 2017 to December 2020 were reviewed. The perioperative data were collected, and then the mortality was calculated and the risk factors were analyzed.
Femur fracture is a common injury occurring in the young due to trauma as well as amongst the elderly due to fall. Reduction and fixation of femur fractures pose a challenge to the anesthesiologist. These fractures are intensely painful as the pain arises from the periosteum and even slight movement can cause muscle forces to angulate and deform the fractured fragments which apart from causing extreme pain also make the reduction of the fracture quite difficult. Sub-arachnoid block (SAB) is a commonly used technique for lower-limb surgeries. It provides excellent surgical anesthesia and is a largely safe and reliable anesthetic technique. However, for femur fracture repair, positioning the patient for SAB not only causes extreme pain but it also makes administration of SAB difficult due to inappropriate position. Another limitation of SAB is its limited duration of action. Hence, conventional pain management modalities which include opioids and NSAIDs are used to manage pain before and during the administration of SAB and during the post-operative period. These conventional pain management drugs are associated with significant adverse effects and should be used with caution especially in the elderly with multiple comorbids. Recently, fascia iliaca block (FICB) has been used not only as part of multi-modal peri-operative analgesic regime for femur fractures but also to provide adequate analgesia for appropriate SAB positioning. FICB fills the plane underneath the fascia iliaca with local anesthetic and acts on the femoral, lateral femoral cutaneous and obturator nerves and thus provides adequate analgesia for femur fractures for up to 24-48 hours. FICB is also associated with less side effects when compared to conventional pain management modalities and provides adequate unilateral analgesia with fewer autonomic and neurological complications when compared with epidural analgesia. Traditionally, local anesthetics have been used for most of the peripheral nerve blocks (PNB), however multiple adjuncts such as opioids, ketamine and clonidine have been used to prolong the duration of action as well as decrease the local anesthetic dosage. Among the adjuncts, dexamethasone has been used to generally favorable results in PNBs. Dexmedetomidine is another promising drug being used as a local anaesthetic adjuvant in peripheral nerve blocks. It is an alpha-2 agonist, which has shown to have prolonged duration of postoperative analgesia when given with LA for peripheral nerve blocks with other beneficial effects such as reducing the opioid consumption. In this study, the investigators compare dexamethasone with dexmedetomidine as an adjunct when combined with ropivacaine in FICB.
Does the current techniques of internal fixation of vertical neck fracture in young adult patients give a satisfactory radiological and functional outcome at one year follow up?
In general, hip fractures in the elderly are associated with a high one year-mortality up to 36 %. Apart from choosing the proper treatment, optimizing the surgical technique itself offers options to improve the outcome. Early mobilization after hip hemi¬arthroplasty correlates with improved ambulation, reduced need for assisted transfers, and less use of extended care facilities after hospital discharge. Nowadays, in order to reduce soft tissue damage and gain quicker postoperative recovery and faster rehabilitation, various MIS techniques have been proposed. Two of these techniques are the mini posterior approach and the mini direct anterior approach. The direct anterior approach was developed as a true internervous and intermuscular surgical approach with proposed benefits of faster recovery, quicker return to function, and less pain. In theory, the direct anterior approach should cause less tissue damage than mini posterior approach, as it is performed through a plane between neurlogical tissue and intermuscular plane without muscle transection. The aim of this study is to evaluate the clinical and radiological outcomes of the direct anterior approach for bipolar head endoprosthetic hemiarthroplasty in patients with displaced femoral neck fractures in comparison with the mini posterior approach and the traditional lateral approach, for the treatment of the same fractures. The investigators hypothesized that patients undergoing the direct anterior approach would have better clinical and radiological results in comparison with the mini posterior and lateral approach.
In France, the annual incidence of hip fracture is about 80 000 with more than 75% of these fractures occurring in patients aged 80 years old or more. About 10% percent of patients presenting with a hip fracture will sustain a contralateral hip fracture, most within 3 years. The consequences of a hip fracture are dramatic: 20% of patients die in the first year and less than half those who survive regain their previous level of function. Hip fractures are invariably associated with chronic pain, reduced mobility, disability, and an increasing degree of dependence. The efficacy of pharmacological treatments to prevent a contralateral hip fracture is marginal and postponed and compliance is known to be poor. Osteoporosis is associated with cortical thinning and trabecular bone loss. Therefore, the mini-invasive preventive fixation (MIPF) of the contralateral femoral neck is appealing. The effect is immediate and compliance is certain. Morbidity is minimal because it is performed during the same operation as the fixation of the femoral neck fracture. The main objective of this study is to determine whether the mini-invasive preventive fixation (MIPF) of the contralateral femoral neck in patients having a femoral neck fracture is superior to no fixation regarding the occurrence of a contralateral hip fracture within 3 years.
RATIONALE: Collecting and storing bone samples from patients with osteoporotic and nonosteoporotic fracture to quantitatively analyze the differentially expressed proteins to further explain the relationship between bone iron content and bone mineral density (BMD). PURPOSE: This research study is looking at changes of iron content and differentially expressed proteins in bone samples from patients with osteoporotic and nonosteoporotic. fracture.
Blood transfusion is an expensive and finite resource and optimum transfusion threshold in surgical patients is yet to be defined. Patients commonly receive blood transfusions to reduce the risk of myocardial ischaemia or improve perfusion of other organs (e.g. the kidneys), but this treatment may have important adverse effects including postoperative infection. Patients undergoing surgery for fractured neck of femur are often elderly, with co-morbidities and a high risk of postoperative complications, including MI and AKI. We propose to conduct a study with the following aims: 1. To describe the incidence of anaemia and transfusion in patients undergoing surgery for fractured neck of femur. 2. To use clinical and biochemical data to measure the incidence of perioperative cardiac and kidney injury in this group. 3. To evaluate highly sensitive serum troponin and urinary MALDI-MS as possible endpoints in a future prospective randomised trial of perioperative transfusion.
Hip fractures are one of the most frequent operated fractures procedures in orthopedics, with a world wide annual incidence of approximately 1.7 million. These fractures are associated with substantial morbidity and mortality. As populations age and life expectancy increases worldwide, the incidence of these fractures is likely to raise, expected to triple in the next 50 years. The use of fluoroscopy and resultant exposure to radiation, is an integral part of surgical procedures aiming to reduce and fixate the fractured femur. The risk of contracting cancer is significantly higher for an orthopedic surgeon as Hip surgery is a major slice of the total radiation dose. Optimal positioning and control of the imaging intensifier device may result in significant reduction of radiation dose and time and in substantial shortening of the procedure. The investigators hypothesis is that this technique would substantially shorten procedure time and reduce unnecessary radiation exposure for both the patient and the medical staff. Furthermore, by using this technique the investigators can eliminate the need for fluoroscopy technician during the surgery, as there is no need to alternate fluoroscopy views.
Studies have suggested a link with effective pain relief and reduced illness and death in high risk patients. Ultrasound guided nerve blocks have been associated with an increased success rate and allow visualization of all the anatomical structures and the distribution of the local anesthetic on injection. The hospital mortality for patients admitted to hospital from home in the UK in 2006 with a fractured hip is 14.3% (Bottle and Aylin 947-51). The aim of this clinical trial is to determine the effective dose of local anesthetic to provide pain relief to patients with a broken hip using ultrasound to guide needle insertion. The hospital mortality for patients admitted to hospital from home in the UK in 2006 with a fractured hip was 14.3%. Patients for emergency surgical fixation or replacement of broken hip will be recruited prior to surgical fixation. All patients recruited to this study will receive standard anesthesia and surgical fixation of their broken hip. The trial can be divided into two sequential parts; the results of part A will be an amount of local anesthetic which will relieve pain of a broken hip in 95% of all patients. Part B will determine the duration of pain relief provided by the amount of local anaesthetic from part A and blood levels of local anesthetic. In parts A and B a standard pain relieving nerve block to numb the nerves supplying the hip joint will be administered using ultrasound to guide the injection of local anesthetic. The patient will then be observed for 30 minutes during which time the feeling in the upper leg and pain scores will be recorded. Patients with ineffective nerve blocks will be given immediate pain relief and withdrawn from further participation in the study. In part A the amount of local anesthetic for the next patient will be increased or decreased if the nerve block is ineffective or effective respectively. In part B the dose will be the same (calculated from the results of part A). In order to determine the duration of pain relief pain scores will be recorded hourly for up to 24 hours. Blood samples will be taken before the pain relieving nerve block and at 5, 10, 20, 30 and 60 minutes afterwards.
