Abstract
Trochanteric fractures of the proximal femur are the most common lower limb fractures seen in clinical practice. Depending on the size, complexity, and stability of the fracture, it is possible to fixate the fracture using the Dynamic Hip Screw (DHS) system.
Although complications and failures with the DHS system are infrequent, clinical practitioners have stressed the need to evaluate the stability of DHS in relation to its position in the bone during implantation. Stability of the DHS and the individual bone fragments is one of the key factors determining success of the treatment.
Another important factor is the magnitude and method of loading of the bone tissue in the area surrounding the implanted parts of the DHS, which is produced during loading of the lower limb. To carry out this evaluation, we conducted a series of computational analyses using the Finite Element Method
