Active clinical trials for "Fractures, Bone"

Management of comminuted distal tibia fracture (pilon fracture) is still a challenging field. It is recently done guided by the new four column theory of distal tibia. Several approaches were advocated to address and fix each column. Fixation of posterior column is still a wide debate among orthopedic surgeons. This study is conducted to compare outcomes between two modalities for the management of posterior column fracture in pilon fractures.

The aim of this study was to compare the functional and radiological outcomes of fixation by using double plating technique versus replacement using distal femur tumor prothesis as a primary management for the distal femoral fractures in geriatric patients. The hypothesis was that the distal femoral replacement will yield better functional outcome and earlier rehabilitation and return to pre-injury level of activity.

Femoral neck fractures represent about half of the hip fractures and are further divided into displaced and undisplaced fractures. Displaced femoral neck fractures are almost always treated surgically with arthroplasty. However there is an ongoing debate on which implant is superior for undisplaced fractures. A novel implant design (Pinloc) has been developed by Swemac Innovation AB. While the original implant consisted of 2 isolated hook pins, the modified design consists of 3 titanium hook pins interlocked in an aluminum plate. Interlocking is a new principle of implant design and improves fixation and load transfer amongst the pins. The superiority of the modified design is so far only proven preclinically. The role of the Pinloc in clinical use remains unclear. Investigators are planning a randomized controlled trial on undisplaced femoral neck fractures to establish a method for implanting the tantalum markers, to observe the fracture healing process and to further investigate the role of the Pinloc.

This is a prospective clinical trial of tibial plateau fractures treated with internal fixation and a calcium sulfate graft which can be mixed with antibiotics and molded into various bead sizes for implantation into bone defects. The graft material chosen for this study is STIMULAN Rapid Cure (Biocomposites, UK), which is approved for use as a bone void filler and may be mixed with a variety of antibiotics. The combination of STIMULAN + antibiotic in bead form is the "study device". Our primary study aim is to look at resorption and remodeling of the study device into bone. Another important aim of the study is to look at subsidence, or collapse, of the joint surface.

This study is designed to examine if immediate weight bearing on a distal femur fracture fixed with a primary locking plate, either a distal condylar locking plate or a LISS (less invasive stabilization system), is safe and promotes more rapid fracture healing than partial weight bearing, which is standard of care.

A distal radius fracture is a break at the wrist end of the long bone on the outside of the forearm. It is common, and can cause problems with stiffness, pain and use of the hand and arm for several months. This study is investigating whether imagined movements whilst in the plaster improve dexterity, reduce pain or improve movement when the plaster is removed. As this is a pilot study the aim is to test research and assessment procedure to guide further studies. Imagined movements involve imagining the wrist moving, without actually moving the wrist. It has been suggested that immobilisation, for example in plaster, can affect the part of the brain responsible for movement and sensation. It has also been suggested that imagined movement can reduce this impact. This study is investigating subjects over the age of 50 with relatively low impact trauma. Younger subjects and higher velocity injuries will be excluded as this introduces an unwanted variable. Likewise, any fractures requiring surgery, or subjects with pre-existing upper limb injury or deformity will be excluded. Patients will be invited to participate following their attendance at the local Accident and Emergency department in Newport, South Wales, or the minor injuries department at Ysbyty Ystrad Fawr Hospital, Ystrad Mynach. Sampling will run for approximately 2 months and all participants will be given standard exercises. All participants will attend an appointment at approximately 1 week and be randomised into treatment or control group. The treatment group will be taught imagined movements and be asked to perform these for 10 minutes, four times a day, the control group will continue with standard exercises. All subjects will attend again for assessment of dexterity, pain and movement after the plaster has been removed, (4-8 weeks dependent on team). This concludes the study.

A prospective study included 91 patients, who had single level thoracolumbar fracture with Cobb's angle ≤ 25⁰, underwent posterior fixation. Forty four patients underwent short segment fixation with screws into the index level, and 47 patients underwent long segment fixation with skipped index level. The angle of correction, pain, and neurological state were regularly assessed

20 patients with distal humeral fractures (AO 13-A1 - AO 13-C3) were included in the current study since 2014. After completing the randomization plan, patients were distributed into two groups for different variable angle locking plates (DePuy Synthes VA-LCP vs. Medartis Aptus Elbow). Clinical and radiological follow-ups were conducted 6 weeks, 12 weeks, 6 months and 12 months after the operation.

To compare surgical outcomes from medial epicondyle fracture fixation with absorbable cartilage nails to those from traditional Kirschner wire fixation.

Cervical trauma is a common cause of disability following spinal cord injury, especially in athletic populations. The biomechanics in the atlantoaxial joint carry more than 50% of the rotational movement which can be affected in transverse ligament tear associated with odontoid fracture type II. Odontoid fracture type II considered an unstable fracture with a high rate of non-union in conservative treatment. Limitation of the odontoid screws in some cases gives the chance of posterior cervical fixation to have the superior role. Use of polyaxial screws in Harms technique gives the best results in maintaining the majority of the biomechanics. Purpose: our aim in this study to evaluate Harms technique in those patients regarding pain improvement and restoration of the motor power and to report the complications. Study design: A retrospective case series study. We Used the Frankel grading system to evaluate the postoperative neurological state.
