Finite Element Simulation of the MRTA Test of a Human Tibia
… (FE) simulation of the MRTA test of a human tibia was developed to identify dominant parameters that will possibly make linear prediction algorithms more suitable for estimating bone quality. Five FE models were developed in stages by adding complexity. Starting with a solid mesh of the …

Modular prosthetic reconstruction for primary bone tumours of the distal tibia in ten patients
… benign and malignant bone tumours of the distal tibia yielding good oncological and functional results. However, in selected patients where limb salvage is feasible and amputation unacceptable to the patient, limb salvage using a distal tibial replacement (DTR) can be considered. This study aims …

COMPARATIVE BIOMECHANICAL ANALYSIS OF SURGICAL FIXATION TECHNIQUES WITHIN THE PROXIMAL TIBIA AND FUSION TECHNIQUES WITHIN THE LUMBAR SPINE
Novel or augmented orthopedic surgical techniques have the potential to improve patient care and outcomes, but their efficacy is often difficult to quantify. Establishing biomechanical models of physiological trauma and repair within orthopedic load bearing tissues in cadaveric samples provides an …

Translation der Menisken und Femurkondylen relativ zur Tibia bei Patienten mit vorderer Kreuzbandruptur - Analyse mit der offenen Magnetresonanztomographie
Objective: To analyze menisco-tibial and femoro-tibial translation patterns in healthy and ACL-deficient knees in different knee flexion angles under muscle activity. Methods: The ACL-deficient and contralateral healthy knees of 10 patients were examined with an open MR system at 30° and 90° of …

Intramedullary nailing of open tibia and femur fractures through the supra & infrapatellar approach. Is septic arthritis a real concern?
… the supra/infrapatellar approach during tibial nailing and the retrograde approach during femoral nailing. This potential risk stems from the mechanical bridging of the knee joint in both methodologies. The susceptibility to this risk increases notably in cases involving open fractures, …

Mechanical Response Tissue Analysis: Inter- and Intra-trial Reliability in Assessing Bending Stiffness of the Human Tibia in College Aged Women
… EI has been limited to the ulna; however, the tibia requires further investigation due to its central involvement in many human activities and exercise-related clinical problems, e.g. stress fracture of the lower leg. To evaluate the inter- and intra-reliability of tibial EI, 22 healthy women …

Using finite element models under multiple loading conditions to improve the association between radius and tibia microarchitecture and prevalent osteoporotic vertebral fracture
Bone microarchitecture differences at the tibia and radius, measurable by high-resolution peripheral quantitative computed tomography (HR-pQCT) exist between individuals with a prevalent vertebral fracture and healthy controls. As fracture is a result of mechanical failure, FE models of these sites …

Radiographic Union Score for Tibia (RUST) scoring system in adult diaphyseal femoral fractures treated with intramedullary nailing: an assessment of interobserver and intraobserver reliability
Objectives The Radiographic Union Score for Tibia (RUST) scoring system has been validated in multiple studies assessing the healing of tibial fractures. Our objective was to assess the inter and intraobserver reliability for the RUST in diaphyseal femoral fractures treated with intramedullary (IM) …

Late-onset Blount's disease
In 1937 WP Blount published a review of tibia vara or osteochondrosis deformans of the proximal tibia. Late-onset Blount's disease is varus deformity of the proximal tibia that occurs at or after 6 years old (excluding late presenting infantile Blount's) and has an associated femoral varus.
