Which type of traction might involve the use of heavyweight to provide a pulling force?

Skeletal traction is characterized by the use of heavyweight to create a pulling force that directly affects the skeletal system. In this type of traction, pins or wires are surgically inserted into the bone, and heavy weights are attached to these fixtures. This approach allows for a significant amount of force to be applied, which is crucial for realigning fractures or dislocations and for ensuring proper healing.

The application of heavy weights in skeletal traction provides a consistent extension and stabilization of the affected limb or joint, allowing for gradual adjustments. This method is often used when more intensive force is required compared to other forms of traction.

In contrast, skin traction relies on adhesive pads or straps applied to the skin, which are less effective at delivering substantial pulling forces. Manual traction uses the therapist's hands to apply traction, which also does not allow for the sustained heavy weight that skeletal traction does. Overhead traction typically involves pulleys and is often used for rehabilitation, but it does not involve the insertion of weights into the skeletal system as skeletal traction does.

Thus, the distinctive feature of skeletal traction is its ability to use significant weight through direct connection to bone, making it suitable for more severe cases requiring greater force for correction.
