Radiolucent lines
No radiolucent lines were present on screened X-rays at any time point in any of the three zones surrounding the small peg in the CLTP and CTP groups. One patient in the CLTP group had a radiolucent line in zone 6 at 1-year follow-up, one patient in the CTP group had a radiolucent line in zone 6 at all follow-ups, and no radiolucent lines were found in the CSP group.
