An analysis of bone stresses and fixation stability using a finite element model of simulated distal radius fractures

Percutaneous Pinning of Distal Radius Fractures: An Anatomic Study Demonstrating the Proximity of K-Wires to Structures at Risk

“…A minimum of 3 K-wires in an orthogonal configuration, with 2 radial styloid K-wires and 1 or 2 from the dorsal rim of the distal radius just distal to Lister's tubercle, can provide reduction and stabilization of the fracture. 14,15 However, some 3-part fractures may require a transverse subchondral radial K-wire to buttress a depressed intra-articular fracture. A dorsoulnar Kwire is often used to fix a fracture of the dorsoulnar aspect of a lunate facet.…”

“…The 5 K-wire entrance sites include a dorsal radial styloid longitudinal wire, volar radial longitudinal wire, transverse radial styloid wire, dorsal rim K-wire, and a longitudinal K-wire at the dorsoulnar margin of the distal radius. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] MATERIALS AND METHODS Fifteen fresh-frozen cadaver upper extremities with an average age of 61 years were dissected after simulation of our technique of percutaneous pinning. There were 6 right and 9 left upper extremities from 8 men and 7 women, with no evidence of disease or trauma.…”

Buttressing angle of the double-plating fixation of a distal radius fracture: a finite element study

“…The finite element (FE) method provides mechanical responses and alters parameters in a more controllable manner, driving its common use as an analytical tool in biomechanical studies [1,2,7,9,17,26]. Tempering this success, ambiguous simulation results usually occur as a result of unrealistic interfacial condition assumptions between the different materials/components [4,17,19,26,29]. Therefore, non-linear FE analysis with reasonable interface conditions that can simulate the friction between a plate and bone interface is needed to calculate the detailed mechanical characteristics of a double-plating fixation system.…”

Conservative Treatment of Distal Radius Fractures, Importance of Radial Height

“…75-80% of radius distal end fractures are extra-articular stable fractures and can be treated conservatively in the Emergency Department2 [2]. However, approximately 20% of these fractures are unstable and surgical treatment is required and decision on conservative treatment or surgery still remains a debate for some particular types of fractures [1,2].…”

“…75-80% of radius distal end fractures are extra-articular stable fractures and can be treated conservatively in the Emergency Department2 [2]. However, approximately 20% of these fractures are unstable and surgical treatment is required and decision on conservative treatment or surgery still remains a debate for some particular types of fractures [1,2]. In the choice of treatment methods, factors such as the type of fracture, the patient's age, lifestyle, accompanying health problems, compliancy to treatment, physical and mental capacity must be considered [3,4].…”
