Distal radius bone fracture termed a volar Barton fracture takes place when the ventral portion of the bone is displaced. This fracture happens obliquely within the joint itself. This is the case report of a 52-year-old female, who met with a road traffic accident and injured her left wrist. After the necessary investigation, she was diagnosed with a volar Barton fracture of the left wrist without any neurological deficits. After this, she was managed with open reduction and internal fixation with plate osteosynthesis. Postoperatively, the patient complained of pain around the left wrist joint and there was also restriction in the movements of the left wrist, which caused it to be difficult to perform everyday tasks. We report that following surgery, physical therapy intervention significantly reduced the intensity of pain, improved the range of motion, and strength of the muscle, and remarkable progress in the patient's functional independence. An Upper Extremity Functional Index was used as an outcome measure.
