Surgical correction of kyphosis in patients with camptocormia due to Parkinson's disease: a retrospective evaluation.

Camptocormia or 'bent spine syndrome' is a rare manifestation of Parkinson's disease. The postural deformity can be a great source of disability. Camptocormia is typically not responsive to dopaminergic medication. Results with deep brain stimulation to treat camptocormia have been mixed but generally poor. The authors report two cases of camptocormia in Parkinson's disease treated with spinal corrective surgery. Despite prolonged postoperative courses, including a high complication rate and the need for multiple revisions, both patients benefited from the procedures.
