Fractures, especially when they occur in hand, are one of the traumas that significantly affect the quality of daily life. Metacarpal fractures are among the most common types of hand fractures, and it is essential to treat them effectively to restore normal hand function. This study uses the finite element method to analyze the effectiveness of locked plates, Kirschner wires, and a combination of both in treating intra-articular metacarpal head fractures. Using computed tomography data from an individual who suffered hand trauma, a three-dimensional metacarpal bone model and fracture line were created. Finite element-based analyses were conducted for models created for three different treatments, and the equivalent stress results obtained from the analyses were evaluated. The findings indicate that combining a locking plate and two crossed Kirschner wires produces lower stress values than the other two methods. This result demonstrates that the combined method provides relatively greater stability than the locking plate alone. Additionally, the method using only the Kirschner wire was found to have the highest stress values among the three methods examined, indicating it is the least stable method. Consequently, it has been concluded that the combination of a locking plate and two crossed Kirschner wires is more effective for the treatment of intra-articular metacarpal head fractures.
