Filter by:The goal of this clinical trial is to investigate the hypothesis that there are none difference in the treatment result of orthognathic surgery on the lower jaw, with interoperative wisdom tooth removal rather than preoperative wisdom tooth removal. In patients with severe dental malocclusion combined with a dentofacial deformity. The main question it aims to answer are: • Is there a difference in the degree of complication and the patient's perception, with inter-operative wisdom tooth removal rather than pre-operative wisdom tooth removal. Participants will be will be divided into two groups, with one group having their wisdom teeth removed 6 months before their jaw moving surgery and the other group having their wisdom teeth removed in connection with their jaw moving surgery.
This is a single centre, randomised, patient blinded pilot study that will assign 40 participants with medial knee osteoarthritis undergoing medial opening wedge high tibial osteotomy (MOWHTO) to either current standard of care with TOMOFIX plating system, or utilise patient specific instrumentation and custom-made plate development, with BodyCAD Fine Osteotomy. If the definitive study is deemed feasible, an additional 110 participants will be randomized, for a total of 150 participants.
An osteotomy is a standard surgical operation in which one or more bones are cut or lengthened or re-shaped. While planning for osteotomy, the surgeon sometimes uses a custom-manufactured cutting guide. The investigators are testing a relatively new approach called mixed reality navigation in planning this surgery in this study. For the purpose of this study, the investigators will compare the accuracy of performing osteotomies with the aid of mixed reality navigation as compared to osteotomies that were performed using prefabricated cutting guides for patients in the past few years.
This is a multicenter, prospective, Post-market Clinical Follow-up (PMCF) Study on the ZNN Bactiguard Cephalomedullary Nails. The objective of this study is to collect data confirming the safety, performance, and clinical benefit of the study device and instrumentation when used for the temporary internal fixation and stabilization of trochanteric, sub-trochanteric or shaft femoral fractures and osteotomies. This is a CE-marked device already available on the market and the aim of the study is to comply with the post-market surveillance requirements.
This is a multicenter, prospective, Post-market Clinical Follow-up (PMCF) Study on the ZNN Bactiguard Antegrade Femoral Nails. The objective of this study is to collect data confirming the safety, performance, and clinical benefit of the study device and instrumentation when used for the temporary internal fixation and stabilization of femoral fractures and osteotomies. This is a CE-marked device already available on the market and the aim of the study is to comply with the post-market surveillance requirements.
Group A: Patients suffering from midfoot arthritis after failed prior conservative therapy who undergo a reverse distal metatarsal minimal-invasive osteotomy Group B: Patients suffering from midfoot arthritis after failed prior conservative therapy who undergo a fusion of one or more midfoot (tarsometatarsal) joints
The study is a single-center, retrospective, non-randomized, non-controlled and consecutive series post-market study. The purpose of this study is to confirm safety, performance and clinical benefits of the DVR Plates. The primary objective is the assessment of performance by analyzing fracture healing. The secondary objective is the assessment of safety by recording and analyzing the incidence and frequency of complications and adverse events.
For severe recurrent patellar dislocation with poor patellar maltracking, derotation osteotomy is an effective clinical treatment. However, derotation osteotomy requires very high requirements for the surgeon. It is necessary to determine the osteotomy surface, control the axis and complete internal fixation in three dimensions. The deviation of the osteotomy surface may cause deformities such as postoperative knee valgus, knee hyperextension, or restricted extension. The hypothesis of this study is to design a 3D osteotomy template for derotation osteotomy with the aid of computer-assisted simulated surgery. Compared with traditional osteotomy, it can effectively improve the treatment effect of recurrent patellar dislocation due to poor patellar maltracking. The incidence of postoperative knee valgus shortens the operation time and reduces the number of intraoperative fluoroscopy. This study intends to adopt a randomized controlled study, and the selection criteria are adolescent patients with recurrent patellar dislocation, aged >14 years, with a positive J sign. The experimental group used mimics 20.0 software to reconstruct the three-dimensional model of the patient based on the full-length images of the lower limbs in the weight-bearing position and the CT of the hip, knee and ankle before the operation. The osteotomy template was designed and 3D printing technology was used to make the osteotomy template for intraoperative osteotomy. The control group used traditional de-rotation techniques. The knee joint range of motion, patella stability, residual rate of J-sign, knee valgus angle, femoral anteversion angle, gait analysis, etc. were compared between the two groups after surgery, and the differences between the two surgical techniques were evaluated
The iliac crest is one of the most commonly used bone graft sources, especially in pediatric pelvic osteotomy operations for developmental dysplasia of the hip (DDH) and Legg-Calve-Perthes disease. In this study, we aimed to identify the effects of inner side and two-sided approaches for iliac crest bone harvesting on post-surgery ilium growth in children.
Humeral intercondylar fractures are very challenging in clinical treatment. There are many problems not clear. One of the important problems remained to be solved is which fixation method can achieve the best effects after olecranon osteotomy. Therefore, the investigators are going to perform a retrospective analysis of patients with distal humerus fractures admitted to their hospital in 2012-2017 to compare the functional outcomes of elbow joints with tension-band fixation and plate fixation after olecranon osteotomy.
