Minimally Invasive Spine Surgery for Kyphoscoliosis in a Patient With Parkinson’s Disease: A Case Report

The surgical treatment for severe deformity correction in patients with Parkinson's disease (PD) is usually challenging, requiring lengthy fusions, and with a high risk of postoperative complications. We present a patient with severe kyphoscoliosis and medical history of PD undergoing minimally invasive surgical deformity correction. A 75-year-old female with a 10-year history of medically controlled PD presented at our hospital's outpatient reporting progressive postural changes during the last two years and a half. On clinical examination, we recognized severe kyphoscoliosis associated with Pisa deformity, in the absence of any neurological manifestations. On the initial x-rays, the coronal angulation was 56° in the lumbar area with a significant lateral shift of the trunk, while the right ribs were close to the iliac crest. The patient underwent deformity correction with percutaneous pedicle screws from T5 to S1, a percutaneous transverse process hooks at T5, and transforaminal lumbar interbody fusion at L5-S1. The total duration of the operation was seven hours, and the estimated blood loss was approximately 300 mL. Clinically, the patient's posture improved significantly, alleviating any preoperative compensatory mechanisms such as knee flexion. The postoperative x-rays revealed a very satisfying correction in both the coronal and sagittal planes (20.1 degrees and 26.6 degrees, respectively). Our current case report showed that MIS constitutes a viable alternative for deformity correction in selected patients with PD as part of a multidisciplinary approach. Proper patient selection requires a detailed medical history and a complete neurological and musculoskeletal examination by a dedicated healthcare provider.
