Abstract
Introduction
It is a generally accepted standard surgical practice to fill-in the metaphyseal defect zones resulting from the reduction of tibia compression fractures. The development of various innovative bone substitutes is also currently on the increase.
Materials and methods
In our prospective study, we used Ostim®, a novel resorbable nanocrystalline hydroxyapatite paste, together with Cerabone®, a solid hydroxyapatite ceramic, in combination with angularly stable osteosynthesis to treat 24 tibia compression fractures. Types B2 and B3, as well as types C2 and C3 fractures, according to the AO classification, were included in the study.
Results
The mean total range of joint motion in terms of flexion and extension was improved from the immediate postoperative value of 79 ± 14° to 97 ± 13° at 6 weeks after surgery, to 109 ± 16° at 3 months, and finally to 118 ± 17° at 1 year. In three patients, a delayed wound healing was observed as a local complication.
Conclusion
The use of the Ostim® and Cerabone® combination is an effective method in treating tibia compression fractures with large defect zones left after reduction.
