Neuromodulation of the suprascapular nerve

Area of Science:

• Orthopedics
• Pain Management
• Neurology

Background:

• The shoulder joint's complex anatomy allows high mobility but is susceptible to pathologies causing chronic pain.
• Chronic shoulder pain, often from adhesive capsulitis, severely impacts daily life and work, necessitating effective treatments.
• Adhesive capsulitis, a condition causing shoulder stiffness and pain, presents a significant challenge in pain management and functional recovery.

Observation:

• A patient with a history of 7 surgeries presented with chronic, debilitating shoulder pain and limited mobility due to adhesive capsulitis.
• Initial multimodality treatment failed to significantly improve the patient's pain or range of motion.
• A suprascapular nerve block provided dramatic pain relief, indicating the nerve's role in the patient's pain.

Findings:

• Permanent implantation of a suprascapular nerve stimulator led to dramatic improvements in pain and shoulder range of motion.
• Peripheral nerve stimulation (PNS) of the suprascapular nerve, combined with multimodal therapy, effectively treated the patient's complex shoulder pathology.
• This case highlights the potential of suprascapular nerve stimulation for managing adhesive capsulitis with refractory pain and immobility.

Implications:

• Suprascapular nerve stimulation presents a novel therapeutic option for challenging cases of chronic shoulder pain and adhesive capsulitis.
• This approach may improve quality of life and reduce the socioeconomic burden associated with debilitating shoulder conditions.
• Further research into peripheral nerve stimulation for shoulder pathologies could offer new avenues for pain management and functional restoration.
