Active clinical trials for "Fracture Dislocation"

This study is a multicenter prospective randomized control trial comparing hardware retention (HR) to removal of hardware (RH).

The objective of this study is to collect and evaluate long-term clinical outcomes data in order to better understand the safety and performance of the Equinoxe Proximal Humerus Fracture Plates over time. This study will follow subjects for a period of up to 10 years post-surgery.

Neck injuries are a common problem among blunt trauma victims with more than 8,000,000 cases being seen annually in U.S. and Canadian EDs. While the majority of these cases represent soft tissue injuries, 30,000 patients suffer cervical spine fractures or dislocations and approximately 10,000 suffer spinal cord injury. There are no readily available national Canadian data on ED visits such as those provided by the U.S. National Hospital Ambulatory Medical Care Survey. The prevalence of potential neck injury can, however, be reasonably estimated for Canadian EDs. Extrapolation, on a population basis, from reliable U.S. figures suggests that 1.3 million potential neck injury patients are seen annually in Canada. Only 0.9% of these patients are found to have cervical spine fractures or dislocations.

The Lisfranc ligaments are a group of ligaments that connect the bones of the middle portion of the foot to each other. The Lisfranc ligaments allow for a normal and stable range of motion and shape to the foot. In certain foot fractures where the Lisfranc ligaments are damaged, the constraint and stability it had given to the middle of the foot is lost. Attempted activity at the foot will result in pain and abnormal motion. If injury to the Lisfranc ligaments is left untreated, the eventual end result is foot arthritis and deformity. The current standard orthopaedic treatment of foot fractures with Lisfranc ligament injuries is surgery. The foot fractures are fixed with metal screws. The Lisfranc ligaments are fixed by compressing the space between the middle bones of the foot with steel screws. These screws allow for ligament healing. As the ligaments heal, the patient should not resume activity with the fixed foot too soon as the screw may break. Upon breakage, the ligament repair may fail and the screw is now difficult to surgically remove. Regardless of breakage, a second surgical procedure is often recommended to remove the steel screw 6 months after foot surgery. This allows for a complete return of normal foot range of motion, but at the cost of a second surgical procedure. The investigators hypothesize that absorbable screw fixation of the Lisfranc ligaments does not yield significant differences in postoperative foot stability, ligament function, and symptoms when compared to steel screw fixation. In addition, absorbable screw fixation of the Lisfranc ligaments offers the advantage that a second surgical procedure to remove the screw is not necessary.

The different proportion samples of PLGA-Mg were made in this study. Then, they would be placed in the femoral condyle of the New Zealand rabbits. The appropriate proportion of PLGA-Mg is obtained after the experiment, which will be used to make the plate or screw to fix the fragments. Then, the clinical role for bone will be assessed.

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.

It was reported that satisfactory postoperative outcome was difficult to obtain for the pelvic or acetabular fracture in old people. The less invasive surgical method was conducted in this study. Then, the clinical results were compared with the patients treated using traditional methods to assess the less invasive method.

This study evaluates fracture healing, anatomic reduction and return to functioning in patients with unstable Weber C type fractures of the ankle. Best outcomes are obtained when a good alignment of the ankle joint is maintained and natural function of the syndesmosis (space between the tibia and fibula bones) is restored. The syndesmosis and ankle joint is stabilized by a series of ligaments which are often damaged in Weber C type fractures. Current syndesmosis repair techniques traverse the tibia and fibula, but do not anatomically reconstruct the ligaments. The investigators will compare reconstruction of the unstable syndesmosis by open reduction and internal fixation using a syndesmosis screw coupled with anterior ligament (AiTFL) anatomic repair technique (ART) to percutaneous repair using a syndemosis screw only (SCREW). Radiographic, pain and functional outcome scores will be compared between the groups using validated outcome measures.

The novel plate could be used to manage acetabular fractures involving quadrilateral surface and posterior column, which may lower the intraoperative blood loss and reduce complication rate.

The purpose with the study is to evalute if early mobilsation after surgery in patients vid elbow frakture-dislocation may lead to better armfunction and reduce common complications as stiffnes in the elbow. After surgery patients will be randomised to either early mobilisation (exercise treatment 3 Days after surgery) or ordinary treatment (plaster and exercise treatment 3 weeks after surgery).
