Percutaneous Kyphoplasty for Osteoporotic Vertebral Compression Fractures Associated with Spinal Canal Encroachment without Neurological Symptoms

However, whether this approach is suitable for osteoporotic vertebral fractures with spinal canal encroachment remains controversial. MATERIAL/METHODS: Of 526 patients who underw...

Sumario:BACKGROUND: Percutaneous kyphoplasty (PKP) has been widely used for osteoporotic vertebral compression fractures (OVCFs). However, whether this approach is suitable for osteoporotic vertebral fractures with spinal canal encroachment remains controversial. MATERIAL/METHODS: Of 526 patients who underwent PKP at our hospital, 40 had conditions associated with spinal canal encroachment, and were enrolled in the study. Detailed physical, neurological, and radiological examinations were performed on each patient before and after surgery and at the followup. A visual analog scale (VAS) and the Oswestry Disability Index (ODI) were used for the clinical assessment. The vertebral body height, the local kyphosis, and the spinal canal width were used for the radiological evaluation. RESULTS: There were 11 male and 29 female patients, with a mean age of 71±8 years. The VAS score decreased from 6.4±0.7 preoperatively to 1.6±0.7 postoperatively and to 2.3±1.5 at the last followup visit. The ODI score was 78±9.5 before surgery, declined to 24±11.3 after surgery, and was 27.6±12.5 at the last followup visit. The vertebral body height increased from 11.7±4.3 mm to 14.6±4.4 mm. The local kyphosis decreased from 15.0±10.7 degrees preoperatively to 8.5±11.3 degrees postoperatively. The spinal canal width remained stable, at 8.5±2.0 mm before PKP and 8.7±1.9 after PKP. CONCLUSIONS: PKP effectively relieved back pain in OVCF patients with spinal canal encroachment. Their social function improved as well.
