Reduction in femoral shaft fractures can be difficult to achieve with minimally invasive techniques. Malalignment and high intra-operative radiation exposure can result. The hypothesis was that robot-assisted fracture reduction could improve the quality of reduction while reducing the amount of radiation exposure. A robot system was developed that allows(More)
A fundamental step in Computer Assisted Surgery (CAS) is the registration, when the preoperative virtual data and the corresponding operative anatomy of the region of interest are merged. To provide exact landmarks for anatomical registration, a tubular external fixator was modified. Two intact pelvic bones (one artificial foam pelvis and one cadaver(More)
OBJECTIVE Evaluate safety and reliability of internal fixator for the treatment of intra-articular and periarticular distal femur fractures. METHODS Retrospective data evaluation of 28 patients with 29 fractures fixed with internal fixator was performed. There was a predominance of male patients (53.5%), with 52% of open wound fractures, 76% of AO33C type(More)
PURPOSE Biomechanical properties of locking plate and angle blade plate constructs in opening-wedge distal femur osteotomy were compared, with special attention to the impact of opposite cortex breakage and buttressing. METHODS Forty-eight synthetic femora underwent a lateral opening-wedge distal femur osteotomy, which was fixed either with a locking(More)
BACKGROUND This meta-analysis aimed to determine the bone union rate of bone defects treated with the different autologous bone graft techniques. METHODS The PubMed and the Cochrane Library databases were searched using the terms: 'fracture' AND ('bone loss' OR 'defect' OR 'defects') AND 'bone graft', restricted to English language, to human species, and(More)
BACKGROUND Foot and ankle injuries are frequent in emergency departments. Although only a few patients with foot and ankle sprain present fractures and the fracture patterns are almost always simple, lack of fracture diagnosis can lead to poor functional outcomes. AIM The present study aims to evaluate the reliability of the Ottawa ankle rules and the(More)
Complex fractures of the lateral tibial plateau may extend to the posterior rim of the knee and to the tibial spines. Displaced fractures of the posterolateral corner of the tibial plateau may result in joint incongruity and instability, especially with the knee in flexion. Anatomical reduction of the joint surface and containment of the tibial rim are the(More)
No surgical technique recreates native posterior cruciate ligament (PCL) biomechanics. We compared the biomechanics of five different PCL reconstruction techniques versus the native PCL. Cadaveric knees (n = 20) were randomly assigned to one of five reconstruction techniques: Single bundle all-inside arthroscopic inlay, single bundle all-inside suspensory(More)
BACKGROUND The use of bandages improves quasi-static posture control in individuals with knee osteoarthritis, but it is unknown whether this increased sensory input influences postural control in dynamic tasks. OBJECTIVE Assess the effect of bandage use on motor performance and reported pain in individuals with knee osteoarthritis during obstacle(More)
During pregnancy, high progesterone and relaxin levels produce physiological ligament relaxation on the pelvis. Therefore, moderate pubic symphysis and sacroiliac joints relaxing provide birth canal widening, thereby facilitating vaginal delivery. Sometimes, functional pain or pelvic instability may occur during pregnancy or puerperium, which is defined as(More)
