The experimental study of the hybrid fixation in ACL reconstruction
2012
Abstract The article is approaching an interesting topic regarding ACL reconstruction using the hamstring tendons (semitendinosus and gracilis) as the graft. The initial graft fixation after ACL reconstruction is mechanical and it must assure the stability of the system until the biologic integration takes place. No fixation system is as strong as the native ACL insertion. Therefore, hibrid fixation like an improvement of simple fixation is a field worth studying. The fixation shown in this article is the Hybrid fixation consisting of direct fixation with interference screw and an extra cortical fixation over a cortical screw.
Guidance and Guideline-recommendations for the treatment of femoral neck fractures Romanian Society of Orthopaedics and Traumatology- SOROT 2018
2018
Abstract Two types of femoral neck fractures are nowadays identified: those resulting from low energy trauma, usually by direct by falling on the hip, in patients with affected bone stock (the so-called “fragility fractures”) and those produced by high energy trauma, even in younger people, with normal bone stock. These recommendations are addressed to the first category. for which impaired mineral bone density (MBD), osteopenia, and osteoporosis represent major enabling factors. These recommendations refer to classification-based local and general treatment of femoral neck fractures (excluding the basilar neck ones). The presumptive and definitive diagnoses include the precise description …
Biomechanical Study of the Osteoporotic Spine Fracture: Optical Approach
2021
Background and objectives: Osteoporotic spine fractures represent a significant factor for decreasing quality of life in the elderly female population. Understanding the mechanisms involved in producing these fractures can improve their prevention and treatment. This study presents a biomechanical method to produce a vertebral fracture, conducted on a human spine segment, observing the displacements and strains in the intervertebral disc, endplate, and vertebral body. Materials and Methods: We performed two tests, one corresponding to an extension loading, and the second to an axial loading. Results: The maximum displacement in the target vertebral body presented higher values in the case o…
Effect of patella resurfacing on functional outcome and revision rate in primary total knee arthroplasty (Review).
2021
Anterior knee pain, as well as patellofemoral disorders, after total knee arthroplasty are important reasons for revision in total knee arthroplasty. Current prosthesis designs include patellar components for patella replacement, and together with improved rational design of the prosthesis and advancement in knee alignment these appear to reduce the incidence of anterior knee pain following total knee replacement, even if the etiology of anterior knee pain remains unclear. However, new complications related to patella resurfacing emerge with this approach. At present, there are three strategies involving patella replacement in total knee arthroplasty: There are surgeons who always replace t…
