The complex regional pain syndrome (CRPS) is an agonizing and disabling condition that can affect one or more extremities. Contrary to expectation, sporadic case reports about lower limb CRPS are present in literature. The usual sequence of events with respect to CRPS has always been prior trauma or inciting event, leading to manifestations. We hereby present a case of prolonged and undue immobilization without physical therapy, leading to CRPS in a susceptible phenotype. However, the unique feature of this case was severity of osteoporosis leading to bimalleolar fracture. To the best of our knowledge, there has been no case report of CRPS, leading to fracture.
