How does Russell traction provide adequate skin traction?

A. Russell traction provides adequate skin traction by supplying a continuous pull in two directions—upward at the knee and longitudinal along the leg. This helps to reduce fractures and maintain alignment, especially in femoral fractures. B. Subluxation of the tibia (partial dislocation) is not a goal of traction and would be undesirable. C. Russell traction allows some knee flexion and does not completely prevent it; in fact, it’s designed to maintain the knee in a slightly flexed position. D. While it may allow for some degree of movement, the primary purpose is traction, not preserving range of motion.
