Which complication resulting from a fracture might necessitate the use of an implanted device to block pain perception?

Complex regional pain syndrome (CRPS) is a significant complication that can arise from fractures, characterized by severe pain, swelling, and changes in the skin. It is a condition that is not only distressing but can also lead to prolonged disability and decreased quality of life. One of the hallmark features of CRPS is its resistance to conventional pain management strategies, which makes it particularly challenging to treat.

In cases where CRPS develops, an implanted device such as a spinal cord stimulator may be considered. This device can block pain signals before they reach the brain, thus alleviating some of the debilitating pain associated with this syndrome. The procedure aims to interrupt the continuous pain cycle that characterizes CRPS, presenting an option when other treatments fail to provide relief.

Other complications like heterotopic ossification, deep vein thrombosis, and delayed union, while serious, generally do not necessitate such invasive pain management interventions. Heterotopic ossification involves abnormal bone growth, which might lead to stiffness or discomfort, but is managed differently. Deep vein thrombosis is primarily a vascular issue, focusing on preventing complications related to blood clots. Delayed union refers to a slower than expected healing of the fracture and typically involves supportive care and monitoring rather than pain
