Partial physeal growth arrest treated by bridge resection and artificial dura substitute interposition

We treated four cases of partial physeal growth arrest by resecting the bone bridge and interposing an expanded polytetrafluoroethylene membrane, which has minimal tissue response. We evaluated three cases with sufficiently long follow-up. No apparent recurrence of the bone bridge and no limb length discrepancy occurred in any of the cases. No remodeling after the operation occurred. In one case, which underwent this operation and corrective osteotomy of the proximal tibia, slight recurrence of the varus deformity occurred which was detected only by radiographs, and did not compromise the alignment of the leg. There were no complications.
