Radial cortex transverse distraction help to treat the Raynaud's phenomenon.

Raynaud's phenomenon is a condition that causing vasospasm of the digital extremities and have a great influence on the quality of patients life. Distraction osteogenesis is accompanied with vascularization and regeneration of surrounding soft tissues. There have been no previous reports of using radial cortex transverse distraction for the treatment of RP. Since January 2019 to January 2023, 6 patients with RP accepted radial cortex transverse distraction. They were failed to conventional treatment for at least six months before the surgery. All the patients were followed-up over 1 year. The bone cortex healed without osteomyelitis or fractures. The ulcer of finger healed in one month. The pain and skin pale released after the surgery. The VAS score declined from 6 to 2 and the finger SpO improved. Radial cortex transverse distraction facilitated finger ulcer healing, salvage the hand and improved Raynaud symptoms. These findings suggest that radial cortex transverse distraction may be an effective procedure to treat the Raynaud's phenomenon.Level of Evidence II Therapeutic study.
