Filter by:Aim of this study is to proof the efficacy of in Jena established prophylaxis of new bone formation aside the skeleton with irradiation and compare it with the common literature. Furthermore we want to compare irradiation treatment with the alternative prophylaxis with analgetics from the NSAID type.
Heterotopic ossification (HO) following elbow fracture-dislocation is a well-recognized condition that can lead to reduced range of motion, increased pain, and the necessity for repeat surgeries. Inflammation serves as a pivotal initiating factor in the formation of (HO) following a traumatic event. The inflammatory cascade triggered can lead to the dysregulation of tissue homeostasis, thereby promoting the aberrant formation of ectopic bone. Tranexamic acid (TXA), a Food and Drug Administration (FDA) approved synthetic antifibrinolytic agent, has garnered significant attention for its potential to mitigate the inflammatory response in the context of orthopaedic surgical procedures. This study aims to investigate the hypothesis that reducing soft tissue hematoma during elbow fracture-dislocation surgery through the intraoperative administration of TXA, can alleviate the occurrence or severity of ectopic bone formation. Methods: A prospective randomized study was conducted on patients with elbow fracture-dislocation who underwent surgery between 2016 and 2022. A total of 50 patients were enrolled and randomly assigned to two groups. The first group received 1 gram of intravenous tranexamic acid before the operation, followed by an additional 1 gram intravenously during wound closure. The second group did not receive any anti-bleeding medication. Patients were followed up at intervals of 2 weeks, 6 weeks, 3 months, and as needed after the surgery. At the end of the follow-up period, there were 23 patients in the first group and 24 in the second group, with a median follow-up duration of 12.7 months. All patients did not receive any other form of HO prophylaxis. Postoperative radiographs and clinical outcomes were assessed and recorded.
The primary goal of this observational study is to demonstrate the incidence of heterotopic ossification (HO) in patients with cementless total hip joint replacement surgery over time and secondly, demonstrate the relationship between celecoxib and HO formation. Lastly, investigators will examine the relationship between HO and patient-reported outcome measures (PROMs).
One of the typical complications which occurs after total hip replacement (THR) procedure is heterotopic ossification (HO). According to current studies abnormal formation of bone after trauma or replacement of the hip could reach even 90% of cases. Heterotopic ossifications are causing the following symptoms, such as: pain, swelling, erythema and warmth along with joint immobility. Those factors could have an impact on maintaining the posture, especially in patients after THR. It is well known since the 90s that the risk of fall among the population older than 65 is high. Data shows that over 30% of those people have such an incident at least once in a year. Majority of them do not have further consequences, however about 10% result in serious trauma to the head and musculoskeletal system. Falls of people who underwent THR are sometimes connected with periprosthetic fractures, which treatment is much more complicated and is associated with a higher risk of failure than treatment of ordinary fractures of the lower limb. What may even worsen the situation is that elderly people very often suffer from many diseases including osteoporosis or neoplasm which increase the risk of fracture. The rate of falls is even higher among patients hospitalised from hip fractures. In the first month after returning home about 14% of patients fall. During the 6 month period after hospitalisation it reaches 53%. So far, the influence of heterotopic ossifications on the risk of falls is unknown in the literature.
Prospective, bi-centric diagnostic, performance study on a new diagnostic procedure with ultrasounds against a reference diagnostic procedure. The primary objective is to study the performance of ultrasound coupled with clinical examination at 1 week of admission for early screening of heterotopic ossification (HO) in patients admitted to a post intensive care rehabilitation unit (PICRU) after a severe neurologic trauma. The CT scan at 5 weeks of admission is considered as the gold standard. CT scan reader will be blinded to clinical data.
One complication that can occur after surgery on the acetabulum is the development of bone in abnormal places such as muscle and soft tissues. There is some evidence that a single dose of radiation to the surgical site within 3 days of surgery will prevent this abnormal bone from forming. However, there are no high quality studies proving that radiation works any better than doing nothing at all. The purpose of our study is to determine whether there is a difference in abnormal bone formation after acetabular surgery when patients are treated with external beam irradiation versus no treatment.
Our overarching aim is to define the pathophysiology, epidemiology, and natural history of HO by following patients from date of injury until full wound healing has occurred and the window for HO has passed. Specific aims Aim 1: To classify the acute and chronic physiologic profiles of fracture patients and how they relate to the development of HO. Here the investigators will look at the systemic derangements to patients' coagulation, fibrinolytic, and inflammatory profiles. Aim 2: Identify the true incidence and time course of HO development after traumatic fracture. To accomplish this the investigators will look at patients who have sustained hip fracture, midshaft/distal femur fracture, humerus fracture, proximal radius fracture, and elbow dislocation/fractures and track follow-up images up to one year after injury looking for HO. Aim 3: Define the histologic characteristics of HO development. To accomplish this aim the investigators will perform a histologic analysis on a sample of injured muscle surrounding the fracture area. Aim 4: To determine what comorbid, iatrogenic, or environmental influences are associated with the formation of HO. To achieve this aim the investigators will evaluate data including injury type, surgery type, operative duration, surgical approach, contamination (open vs closed injury), complications (malunion, nonunion, infection, hardware failure, removal of hardware), hardware type, comorbidities (smoking, cardiac history, diabetes), and medications.
Uncemented Hemiarthroplasty, Radiological Features Comparing Lateral Versus Anterolateral Approach. Comparing leg length discrepancy, femoral offset, valgus/varus position of the stem. Also is there a difference in heterotopic ossification at 12 months.
Heterotopic ossification (HO) is a common complication after surgical repair of elbow trauma. Uric acid is the end-product of purine metabolism that has any physiological and pathogenic potential functions. However, the relationship of HO and uric acid has not been explored up to now. This study aimed to assess the relationship of HO and uric acid. The investigators retrospectively reviewed the demographics of participants who undergone the surgery for elbow trauma in our hospital between January 2012 and December 2018. One hundred participants included in our study. The participants were divided into two groups by the existing HO or not. The serum uric acid between both groups were compared by using the independent samples student T tests.
