The spring portion of the rod has a longitudinal dimension that changes as a function of loading on the rod. When the rod is in contact with a solid surface such as a bone, it maintains contact with such surface even while changing shape due to loading on the rod. When the assembly includes multiple rods attached to the retractor, both spring-based rods and other types of rods may be used in combination.

Abstract: Kits and systems are disclosed that include one or more segments of elastically deformable membrane in combination with one or more external fixation members and optionally in combination with one or more tension protector pads. Also disclosed are methods of use of the kits and systems in methods that involve stretching the elastically deformable membrane and applying the stretched membrane to the skin of a patient, and releasing the tension on the membrane, thus causing compression of the skin to which the membrane is applied. The method may further include the optional steps of inserting one or more external fixation members through the membrane/skin combination and into a bone segment, applying a distraction force to the one or more external fixation members, and separating at least a portion of the membrane so as to release a portion of the tension in the skin at a rate that is similar to a rate at which the distraction force is applied.
