Final answer:
Counter traction in Buck's extension traction can be provided by using a footboard, providing an overhead trapeze, or slightly elevating the foot of the bed.
Step-by-step explanation:
Counter traction is used in traction therapy to prevent shear and friction. In the case of Buck's extension traction, counter traction can be provided by:
- Using a footboard: A footboard is attached to the foot of the bed and helps to anchor the patient's leg, providing a counterforce against the traction force.
- Providing an overhead trapeze: An overhead trapeze allows the patient to lift themselves up using their arms, which creates a counterforce against the traction force.
- Slightly elevating the foot of the bed: Elevating the foot of the bed helps to minimize the shear and friction forces on the patient's body.
These measures help to maintain the effectiveness of the traction therapy and prevent complications.
