It is not exactly known whether guided growths or definitive epiphysiodesis techniques are superior in treating limb length discrepancy (LLD).
Medical records of patients between 2006 and 2012 were reviewed treated either with tension band plating as a guided growth technique (temporary epiphysiodesis) or with a percutaneous drilling technique (definitive epiphysiodesis) because of LLD. Surgery was performed around the knee - in the distal femur alone, the proximal tibia alone or in both. The minimum follow-up was 12 months. Radiographic measurements were performed by two independent reviewers.
Thirty-eight patients were included, 17 treated with temporary epiphysiodesis and 21 with definitive epiphysiodesis. There were no statistically significant differences for age, sex, preoperative LLD and follow-up time. Average follow-up was at 578 days. The reduction of the LLD in 12 months was 5.7 mm in patients treated with temporary epiphysiodesis and 8.4 mm with definitive epiphysiodesis, respectively. This difference was, however, statistically not significant.
In both groups LLD could be statistically significant reduced after 12 and 24 months. Intra- and interobserver reliability of the measurements was excellent.
As in earlier studies supposed, temporary epiphysiodesis with tension band plating seems to correct LLD less powerful compared to definitive percutaneous epiphysiodesis. However, in the present study the differences of LLD correction were not statistically significant.
