A Case Report Illustrating the Combined Use of Cryoneurolysis and Percutaneous Needle Tenotomy in the Treatment of Longstanding Spastic Shoulder Contractures After Stroke.

Adduction and internal rotation of the shoulder is a common presentation in post-stroke patients, and can often be caused by spasticity and musculotendinous retraction causing a contracture of the pectoralis major and minor muscles. A post cerebral arteriovenous malfunction rupture patient with severe refractory left shoulder spasticity with contracture was treated with cryoneurolysis to the medial and lateral pectoral nerves, combined with a percutaneous needle tenotomy to the pectoralis major tendon. There was an improvement in shoulder forward flexion, abduction and external rotation immediately and found sustained at 8 weeks by 50°, 45°, and 15°. The patient noted an immediate cessation of limitation of shoulder abduction, a liberation of range of motion of the shoulder, and looseness in their arm and shoulder. They reported a dramatic improvement in their gait, increased independence, and an improvement in overall quality of life in a structured interview 8 weeks after the procedure. The patient relayed a positive experience with the combined neuro-orthopedic procedure of cryoneurolysis and tenotomy for the treatment of their spastic shoulder. This combined treatment could be considered as a management strategy for patients experiencing shoulder spasticity with contracture.
