Abstract
Introduction
We investigated the effect of high-energy extracorporeal shock wave (ESW) on immature tibial epiphysis in a rabbit model.
Materials and methods
Twenty New Zealand white immature rabbit were used in this study. Animals were divided into two groups and they received 14 kW, 0.6 mJ/mm2, 1,500 or 3,000 shots for three times with an interval of 7 days. After 6 weeks all rabbits were killed. The all tibia epiphysis were assessed by histology. The epiphyseal plaque thickness of right tibiae of the 3,000-shot ESW group was significantly higher than those of the 1,500-shot ESW group and the left tibia epiphyses of the 1,500- and 3,000-shot ESW groups as controls (P < 0.05).
Results
The epiphyseal plaque thickness of right tibiae of the 1,500-shot ESW group was significantly higher than that of the left tibia epiphyses of the 1,500- and 3,000-shot ESW groups as controls (P < 0.05).
Discussion
We demonstrated that high-energy ESW stimulated the growth of immature rabbit epiphysis. The long-term effect of shock wave on the immature rabbit epiphysis deserves further study.
