Abstract

Background: Intravertebral cleft (IVC) is frequently observed in patients with painful chronic, mainly cause of pseudoarthrosis osteoporotic vertebral compression fracture (OVCF). 

Objectives: The purpose of this study was to evaluate the clinical and radiographic results of percutaneous vertebroplasty (PVP) in the treatment of OVCF with IVC. 

Subjects and methods: A retrospective review of 100 patients who underwent percutaneous vertebroplasty to treat osteoporotic compression fractures, IVC sign was observed of 45 patients. Back pain was measured using a visual analog scale (VAS) and physical disability was assessed using the Oswestry Disability Index (ODI). Augmentation of cement injected per vertebral body. Changes of the vertebral body height were assessed on X-ray film in comparison between pre- and postintervention. Results of the intervention were assessed by Macnab standards. Complications during and after intervention were recorded. 

Results: in 44 patients with IVC (08 males, 36 females) with an average age of 74,5 (range 57– 91 years). The most common location of collapsed vertebral are L1 with 37,05%. Vertebral collapse with air is the most common with 58,8%, collapse with fluid and both fluid and air are 23,5% and 17,7% respectively. An average volume of 4ml (2-8ml) of cement injected per vertebral body. There were 13,6% of cases with leakage of cement out of vertebral body. The mean values for the VAS and ODI were 6,77 and 3,48 before PVP, versus 1,73 and 1,8 at the final follow-up;  showed no significant difference between IVC and non-IVC fracture patients. The postoperative vertebral body height were improved with 8,93mm. According to MacNab's classification, postoperative outcomes were rated as good and very good in 79,5% of patients. 

Conclusion: Percutaneous Vertebroplasty to treat OVCF with IVC is a safely procedures, fewer complications, that reducing back pain and improving the quality of life.
