Background:
Kienbock's disease, or osteonecrosis of the lunate, is associated with a history of pain and weakness of the affected wrist. To date, no reports have been published demonstrating use of spinal cord stimulation (SCS) for management of this disease. The patient provided HIPAA compliant informed consent for the inclusion of their clinical information in this report.
Case Report:
A 31-year-old woman presented with a 10-year history of right wrist pain, absent of a history of trauma, that did not improve with conservative therapy, found to be secondary to avascular necrosis of the right lunate bone. A spinal cord stimulator trial and implant were subsequently performed, demonstrating a 75% reduction in pain intensity with paresthesia-free stimulation at 8-week follow-up and return to work.
Conclusions:
SCS can help significantly improve symptoms and function in patients with Kienbock's disease.
