Moreover, the attachments are generally head to tail â that is the 1-carbon of the first isoprene is connected to the 4-carbon of the adjacent isoprene. Already discussed examples of such molecules include the polymers, natural rubber and gutta percha.
Reviewed by Walter Erhardt, MD. Capsular contracture is a breast augmentation complication that develops when internal scar tissue forms a tight or constricting capsule around a breast implant, contracting it until it becomes misshapen and hard. As a result, the breast may feel painful and stiff, and the capsule may affect the appearance or shape of the breast.
The capsule tightens around the implant, causing it to look differently and feel hard. It is uncertain when and why this happens, but it is more common in the first couple months after surgery. However, capsular contracture can happen at any time. You may have a higher risk of contrature following an infection or if the implant shell has been exposed to bacteria.
