Can Screw-only fixations of ACPHT acetabular fractures enhance stability as the standard buttress plate fixation provides?
Abstract: Background: Of acetabular fractures, anterior column posterior hemi-transverse(ACPHT) fractures commonly occur after a fall onto the hip in elderly population. When displaced in these fractures, open reduction and internal fixation using plate and screws is usually required to achieve good functional outcomes. The open procedures, however, involve high complication rates due to surgical invasion; therefore, percutaneous techniques by screw-only constructs have been advocated to minimize these complications. The purpose of …

Biomechanical comparison of Schanz screws placement modes-how can stability by external fixation be raised?
Abstract: AbstractBackground: At present, external fixators are being used widely in open fractures of the long bones and also accepted as a temporary skeletal stabilization even in closed fractures. Therefore, it is essential to increase the stability which is provided by those devices for good outcomes. We hypothesized prior to the study that the greater is the distance between the Schanz screws inserted in each fracture fragment, the higher is the …

Comparison of Lateral and Medial Plate Fixations of Talar Neck Fracture: A 3D-Finite Element Analysis
Abstract: Background: Talar neck fractures are rare, but challenging injuries, because the bone has unique anatomy, and its blood supply makes it difficult to stabilize the fracture and is likely to cause posttraumatic or postoperative complications. Thanks to development of appropriately sized plates, outcomes of plate fixation of talar neck fractures have been improved compared with screw fixation. Although some studies have demonstrated no difference between screw only fixation and screw-plate …

Treatment of Malunited Fracture of the First Metacarpal Base with a Comorbidity of Diabetes by Medical Therapy and Miniplate Fixation: A Case Report
Abstract: Even though every malunited hand fracture requires no intervention, malunion deformities including rotational malalignment and angulation can cause weakness of grasp and pinch. In addition, diabetes mellitus, a general factor of an infection, is an important illness which should be taken into account before undertaking reconstruction. Therefore, malunited fracture of the first metacarpal concomitant with diabetes may pose as a challenging problem, which includes various considerations such as indications, fixation …

Biomechanical Comparison of Tension-Band Wiring Fixations in accordance with Kirschner Wires Placement Modes for Olecranon Fractures: A 3D-Finite Element Analysis
Abstract: Background: Tension-band wiring is a widely accepted fixation technique and remains a standard method of surgical treatment in displaced olecranon fractures. There are 2 techniques according to the Kirschner wires (K-wires) placements; one is to insert the K-wires into the intramedullary canal of the proximal ulna and the other is provided by those anchored into the anterior cortex of the ulna. The purpose of this study was to compare biomechanical …

Residual Nonunion in a Case of Two and-a-half Year Old Child Congenital Pseudarthrosis of Ipsilateral Tibia and Fibula Treated by Intramedullary Fixation with K-Wire and Allogenic Cancellous Strut Graft: A Case Report
Abstract: The pseudarthrosis usually develops during the first two years of life; however, there are reports of cases in which fractures developed before birth and reports of late-onset pseudarthrosis. There is a strong association between congenital pseudarthrosis (CPT) and Type I neurofibromatosis. CPT develops in about 5.7% of patients with NF-I and 40% of patients with pseudarthrosis were found to have NF-I. Main pathology is hyperplasia of fibroblasts with the formation …

A Short-term Evaluation of Limb Reconstruction System as a Primary and Definitive Mode of Management in Fresh Open Fracture in Both Bones of Leg
Abstract: Open fractures require immediate surgical intervention, emphasizing prompt intravenous antibiotic therapy, irrigation, and debridement to minimize infection risks. The Limb Reconstruction System (LRS), which includes Shanz pins, rail rods, and sliding clamps, operates as a single-plane, one-sided rail system. This system provides strong fracture fixation, allows for early weight-bearing, and helps minimize costs. Challenges arise in tibial open fractures due to substantial soft tissue damage and bone loss, often resulting …

Wave plate; what is the angle of its central curved segment which provides biomechanically optimal stability for femoral shaft fracture?:A 3-D Finite Analysis
Abstract: Even though intramedullary nailing of femoral shaft fracture is the standard surgical treatment as it is in tibial fracture, plate fixation might be a choice when the fracture involves open growth plate, patients are of shorter stature or have narrow canals. In these cases, fixation techniques with plate and screws, for example, percutaneous procedures involving wave plate, are useful thanks to minimal invasion and preservation of biological environment surrounding the …

Image-Based Evaluation of Implant Tissue Interface Integrity in Polymer Orthopaedic Devices
Abstract: Polymer orthopedic implants offer radiolucency and mechanical compatibility with bone, but long-term success depends on maintaining a stable implant–tissue interface. Routine imaging is widely available for follow-up, yet interface integrity is commonly judged qualitatively, limiting early detection of fixation compromise and reducing comparability across devices and time points. This work presents an image-based methodology to quantify interface integrity by extracting interpretable interface descriptors from a standardized interface belt around the …

A Smart Investigation on Nanocomposites Composed of Carbon Dioxide-Derived, Repeatable Biological Polymers
Abstract: In recent years, an increasing number of people have begun to focus their attention on the environmental impacts that are caused by the widespread use of therapeutic polymeric composites that are generated from fossil fuels. Another factor that probably contributes to the short shelf life of biomedical polymer products is the fact that many of them are designed to be used just once before being discarded. When a biomedical polymer …
