Perioperative Botulinum Toxin A in the Surgical Management of Seizure-Related Shoulder Instability: A Case Report.

CASE: A 20-year-old woman presented with recurrent bilateral shoulder instability concurrent with severe, treatment-refractory epilepsy. Imaging revealed glenoid bone loss of 25% to 28% and large Hill-Sachs defects bilaterally. Bone graft augmentation of the glenoid and infill of the Hill-Sachs defects was performed bilaterally. Perioperative neuromuscular paralysis of shoulder girdle muscles with botulinum toxin was performed to facilitate recovery. Both shoulders at 2.5 and 4 years, respectively, demonstrate excellent stability and radiographic union despite continued seizure activity.

CONCLUSION

Perioperative neuromuscular paralysis with botulinum toxin may provide early graft protection after the surgical treatment of glenohumeral instability because of seizures.
