The role of heel traction can be summarized as two main functions in clinical practice, namely, to maintain fracture repositioning and to reduce pain. In orthopedic clinics, heel traction is usually used for tibiofibular fractures, to maintain preoperative repositioning or to reduce the pain of symptomatic treatment. In addition, it can also be used for thigh or pelvic fractures, acetabular fractures, and femoral dislocations that are not amenable to tibial tubercle traction or supracondylar femoral traction. Achilles traction maintains a longitudinal length of the limb, which facilitates a second surgical treatment and reduces the difficulty of intraoperative repositioning. In addition, heel traction can keep the affected limb temporarily braked, which is conducive to the blood circulation of the soft tissues in the affected limb, and thus also facilitates the repair of the soft tissues, reduces swelling and alleviates pain.
