Abstract

Objective

To study the distribution of bone cement in unilateral puncture percutaneous vertebroplasty (PVP).

Material and methods

A total of 64 patients with osteoporotic vertebral compression fractures (OVCF) who underwent unilateral PVP were included in this study. The vertebral body was longitudinally divided into four equal parts. The intermediate layer between each part was representative of the part and there were four layers in total. Each layer was divided into 4 regions a, b, c, and d by the crossed lines at the center of the vertebral body. Region c was the first half of the puncture side and region d was the second half of the puncture side. Region a was the first half of the opposite side, and b was the second half of the opposite side. Bone cement filling areas in the four layers and the four regions of each layer were compared.

Results

There were significant differences in visual analogue scale (VAS) scores before and after surgery (P < 0.05). Variance analysis indicated that the bone cement filling ratio of the region b in each layer was significantly lower than the other three regions, and that the bone cement filling ratio of region a was equal to that of the region d.

Conclusion

Unilateral puncture PVP can reduce VAS scores, and plays a role in reducing pain. The bone cement showed a regular distribution.

Zusammenfassung

Ziel

Die Verteilung des Knochenzements bei unilateraler Punktion im Rahmen der perkutanen Vertebroplastik (PVP) sollte untersucht werden.

Material und Methoden

In die Studie wurden insgesamt 64 Patienten mit osteoporotischen Wirbelkörperfrakturen eingeschlossen, die eine unilaterale PVP erhielten. Der Wirbelkörper wurde longitudinal in vier gleiche Teile untergliedert. Die Intermediärschicht zwischen jedem Teil war typisch für den Teil. Insgesamt gab es vier Schichten. Jede Schicht wurde durch die gekreuzten Linien in der Mitte des Wirbelkörpers in die vier Regionen a, b, c und d unterteilt. Region c war die erste Hälfte der Punktionsseite, Region d war die zweite Hälfte. Region a war die erste Hälfte der gegenüberliegenden Seite, Region b war die zweite Hälfte. Bereiche mit Knochenzementfüllung in den vier Schichten und in den vier Regionen jeder Schicht wurden verglichen.

Ergebnisse

Die Werte auf der visuellen Analogskala (VAS) vor und nach dem operativen Eingriff unterschieden sich signifikant (P < 0,05). Wie Varianzanalysen zeigten, war das Knochenzementfüllungsverhältnis der Region b in allen Schichten signifikant geringer als in den anderen drei Regionen. Zudem war das Knochenzementfüllungsverhältnis der Region a gleich dem der Region d.

Schlussfolgerung

Die PVP mit unilateraler Punktion kann die VAS-Werte reduzieren und spielt eine Rolle in der Schmerzlinderung. Für den Knochenzement zeigte sich eine regelmäßige Verteilung.
