Clinical and radiological assessment of results of vertebral body stenting procedure. Introduction: Use of metallic stents along with cement have shown good restoration of the vertebral body in cadaveric spines. We have presented the early results of vertebral body stenting done at Royal Derby Hospitals. Patients and Methods: All patients had a transpedicular approach to the vertebral body. The vertebral body stent was expanded using a balloon as in balloon kyphoplasty. The balloon was removed leaving the stent in place. The resultant cavity was filled with partially cured polymethyl methacrylate in osteoporotic fractures and calcium phosphate cement in traumatic fractures. Radiological assessment included pre operative measurement of vertebral body angle, correction achieved and maintenance of correction at follow up All patients were assessed using the visual analogue score and oswestry disability index. The procedure was done in 14 fractures (10 patients). 9 fractures were traumatic while 5 were osteoporotic fractures. The mean age of the traumatic fractures was 54.28 years while the mean age of osteoporotic fractures was 82.34 years. Mean follow up was 10 months. All traumatic fractures were type A 3.1. Mean vertebral body angle correction achieved was 8.3° (4° to 14.2°). None of the patients lost the reduction at follow up. The mean VAS for pain at 6 months was 3.8. The mean oswestry disability index was 22% for traumatic fractures, while it was 44% for osteoporotic fractures. Vertebral body stenting is a safe procedure. It was successful in restoring the anterior column with encouraging radiological and clinical results.
