[Complex regional pain syndrome type 1 after fracture of distal phalanx: case report].

Complex Regional Pain Syndrome (CRPS) is a disease characterized especially by pain, swelling, limited range of motion, vasomotor instability and patchy bone demineralization in the extremities. In this case, we report a 46-year-old woman diagnosed with CRPS type 1, whose complaints, such as swelling in the left hand, pain, and limitation of movement, started 2 months after a fracture of the distal phalanx in the left 4th finger. Her complaints were reduced with treatment of calcitonin, gabapentin, calcium and vitamin D3, retrograde edema massage, contrast baths, conventional TENS, pulsed ultrasound, desensitization and exercise with range of joint motion. CRPS type 1 should be considered in the differential diagnosis of upper limb pains which start after a fracture of the distal phalanx.
