This study explores the impact of the complex regional pain syndrome (CRPS) on the
lives and mobility of patients, with a particular focus on its emergence as a late complication of
distal radius fractures (DRFs), a common occurrence, especially among an aging population. The
absence of a standardized treatment for the CRPS and the challenge of predicting its occurrence
make it a complex medical issue. This research aims to shed light on the effects of treating the CRPS
through a case study involving a 75-year-old woman with untreated osteoporosis who experienced
a Colles fracture after a fall. The initial management involved repositioning and stabilizing the
fractured forearm with a plaster cast, followed by an operation using percutaneous pinning via a
Kirschner wire. Subsequently, the patient developed CRPS symptoms and was admitted to the
rehabilitation department three months post-fracture. The affected forearm exhibited swelling,
warmth, pain, and severely limited range of motion. Treatment involved a combination of medi-
cations, physiotherapy, and kinesiotherapy. Significantly, the patient experienced notable im-
provement following these interventions. This study underscores the absence of a definitive
standard for CRPS treatment but suggests that proper rehabilitation and pharmaceutical interven-
tions can contribute positively to patient outcomes. The case further highlights the potential asso-
ciation between DRF and CRPS development, emphasizing the need for continued research in this
field.
