Provisions for counter traction must be made. 2. Non slip knots must be used to secure the cords to pulley. 3. The line of pull should be able to counter the deforming forces (eg: abductors in the sub trochanteric fracture and flexors in supra condylar fracture femur). 4. Frequent check of the patients and of the apparatus.

The basic principles of retraction are the same: the assistant places an appropriately shaped retractor(s) on or into the soft tissue surrounding the operating field. The retractors are then manipulated to apply an appropriate amount of traction and counter-traction pressure in order for the surgeon to be able to operate safely.
