NCT06658379
In approx. 10-15% of all fracture patients, there is a prolonged healing time or even a complete absence of fracture healing (non-union). As a result, these patients require further surgical interventions, combined with renewed or prolonged hospitalisation/rehabilitation and incapacity to work. To summarise, this therefore represents a serious socio-economic problem. At present, there is no prognostic method for the early prediction of patients at risk of a disturbed healing process. However, if these patients are successfully stratified, there are already a variety of therapeutic strategies available to additionally stimulate fracture healing. Therefore, the aim is to conduct a prospective clinical study to validate CD8+ TEMRA cells as a prognostic marker of impaired fracture healing. The investigators assume that preoperative CD8+ TEMRA cell expression represents a prognostic biomarker with high diagnostic precision for differentiating between a) normal healing patients, b) delayed healing patients and c) pseudarthrosis patients. Furthermore, the sensitivity and specificity should be high enough, health-economically significant and realisable in clinical routine.
NCT06591585
Midterm radiographic and function follow up of pediatric pelvic fractures managed at Assiut University Hospital ( AUH) with a minimum of 3 years Analysis of all recorded cases of pediatric Pelvic Fracture in AUH trauma unit from 2015 until june 2024
NCT00907296
The primary objective of this study is to investigate the effect of romosozumab compared with placebo on time to radiographic healing of fresh tibial diaphyseal fractures (fractures in the midsection of the shinbone).
NCT04783337
The aim of our study is to improve a mathematical model (FAE) of human bone healing using the example of the distal spoke fracture. Computer-aided strength analyzes of data from hr-pqCTs should provide information about the fracture strength and quality of the newly formed bone at defined times. Laboratory parameters from sober blood analyzes, bone remodeling markers, competitive x-rays, the course of pain, range of motion, grip strength and other easily accessible parameters should be evaluated with the above-mentioned analyzes.
NCT03286270
Early intervention attempts to shorten protracted delayed union (DU) or prevent non-union (NU) fractures are hampered by lack of validated quantitative assessment tools for bone fracture healing during normal and delayed healing processes. In actual practice, sequential X-rays usually follow a pre-determined time interval in patients with fractures.They constitute the best available state of the art used by surgeons to assess the fracture healing course. In an attempt to improve between raters reliability of radiographic assessment of healing, studies have explored a novel radiographic assessment for tibial shaft fractures, the Radiographic Union Scale for Tibial Fractures (RUST). The RUST assesses the presence of bridging callus and a fracture line on each of four cortices (seen on anterior-posterior and lateral views). This callus based scoring system has been since extended to other bones than the tibia in a retrospective case series. It has been renamed modified radiological union score (mRUS) and has shown potential value in bone healing measurement. Based on an initial retrospective study in nail-treated fractures, the first objective of the present investigation is to prospectively validate mRUS as a tool to identify patients at increased risk of DU and NU within the first 75-110 days after fracture occurrence. This prospective validation will be performed on a retrospective cohort of patients having sustained long bone fractures, including both upper and lower extremities. A further objective of the present investigation is to apply the scoring system to tomographic imaging in case of nail/plate treated fractures, deriving a tomographic union score (TUS) and first assess its potential value in bone healing for fractures treated by nails/plates.
