Pain, osteolysis, and periosteal reaction are associated with the STRYDE limb lengthening nail: a nationwide cross-sectional study

Background and purpose — Observing serious adverse events during treatment with the Precice Stryde bone lengthening nail (NuVasive, San Diego, CA, USA), we conducted a nationwide cross-sectional study to report prevalence of from all 30 segments in 27 patients treated Denmark. Patients methods Radiographs were evaluated regarding radiographic changes February 2021. We determined number late onset pain and/or radiographically confirmed osteolysis, periosteal reaction, or cortical hypertrophy junctional area nail. Results In observed 21/30 20/27 patients, i.e., 19/30 12/30 reaction (most often multi-layered), junction between telescoping parts. Late was prominent feature 8 patients. This is likely be prodrome bony changes. Discoloration (potential corrosion) at interface multiple removed nails. 15/30 nails still risk developing complications, not yet removed. Interpretation All should monitored regular intervals until removal. Onset stages limb lengthening, consolidation regenerate, warrant immediate examination hypertrophy, which may associated discoloration recommend removal implants as early possible after regenerate.
