What factor should be considered when choosing screws for fixation in oblique fractures?

Screw length only
Screw diameter only
Both length and torque
Both length and penetration depth

The correct answer is: Both length and penetration depth

When choosing screws for fixation in oblique fractures, it is essential to consider both screw length and penetration depth. The orientation of oblique fractures often requires screws that can provide adequate stability and hold the fragments securely in place. Screw length is important because it needs to be long enough to engage the fractured bone segments without protruding excessively, which could lead to complications. At the same time, penetration depth is critical, as it ensures the screw achieves optimal purchase within the bone's cortex, contributing to the overall mechanical stability of the fracture fixation. This combination of adequate screw length and proper penetration depth ensures that the screw will provide the necessary compression across the fracture line and maintain the alignment of the fracture during the healing process. Balancing these two factors is vital in achieving successful outcomes in treating oblique fractures.
