Filter by:Wide-awake surgery with local anesthesia is a widely described approach to performing numerous minor hand procedures, such as tendon repairs and percutaneous fracture pinning, but is less frequently used for longer procedures such as open reduction internal fixation (ORIF). This is in part due to the need for a tourniquet for improved visualization, however pain-free tourniquet time with local anesthesia is roughly 20 minutes, shorter than the average time for ORIFs (Gillis), for example. While general anesthesia may still be avoided with more proximal blocks such as a brachial plexus or bier blocks, these still require presence of an anesthesiologist during the procedure, increasing human resource utilization and costs. Development of an anesthetic technique for hand surgery which could be performed by surgeons in a clinic setting, that still provides sufficiently long pain-free tourniquet times could decreases costs and wait times. The investigators hypothesize that the pain patients experience after 20 minutes of tourniquet application with local anesthetic infiltration is not due to direct pressure on the proximal arm, but rather distal digital ischemia pain. Previously, it has been shown that ultrasound-guided regional block of the median, radial, and ulnar nerves in the forearm is effective analgesia for awake hand surgery (Winter). Currently, there are no randomized studies investigating if forearm nerve blocks can prolong pain-free tourniquet time compared to local anesthesia infiltration, by blocking this ischemic pain in the distal arm. The investigators' objective is therefore to determine if forearm nerve blocks prolong pain-free tourniquet time compared to local anesthetic infiltration.
The study is a blind randomized clinical study on patients with midface maxillofacial fractures coming to Cipto Mangunkusumo Hospital. The subject is the fracture line who met the inclusion criteria and randomly allocated into the study (locally-made miniplate and screw) and control (BIOMET® miniplate and screw) group through a predetermined randomization list. The healing process is follow up using non-contrast head computed tomography immediately after surgery as a baseline, and 3 months post-op. Afterward, a radiologist consultant as a blinded evaluator will evaluate the score of bone density, and screw loosening, while local tissue reaction after fixation evaluates during the patient's visit outpatient clinic. All scores from points of the evaluation group will be collected and going to statistically evaluated using independent t-test or Mann Whitney test depending on the distribution of the data
Background Fractures of the distal radius are among the most common. Major complications, including irritation and rupture of the extensor tendons, may occur if epiphyseal screws of inappropriate length are used. Questions/Purposes The main objective of the present study was to determine whether the optimal epiphyseal screw length can be determined by reference to the diaphyseal screw length. Methods Forty CT scans were semi-automatically segmented. A 3D model of the volar plate was affixed to each distal radius with simulation. The maximum lengths of the diaphyseal screws, as well as the four distal epiphyseal screws, were measured. Linear regression analysis was performed.
To compare classical pedicle finder versus pedicle finder with impedancemetry on the perioperative radiation exposure of PPTLO. These two devices are already used in common practice.
The aim of the study is to compare Tip-Apex Distance values in two groups of patients after intramedullary nailing of proximal femur. The first group of patients is operated with the help of a 3D reconstruction device connected to the standard fluoroscopy allowing the surgeon to visualize directly the exact position of the tip of the trans-cervical screw while the second group (which is the reference-group) is operated with the help of fluoroscopy alone.
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.
A multicentre randomized controlled trial that will be conducted at Level 1 trauma centres across Canada. It will compare patients who receive open reduction, internal fixation for Sanders IV calcaneal fractures to patients who receive primary subtalar fusion for the same type of fracture. Patients will be followed up for a period of two years from the time of operation with evaluations being performed at 5 time points: 6 weeks, 3 months, 6 months, 12 months, and 24 months.
