“…An analysis of retrieved PRECICE nails documented improvements from the first version to the current version (Panagiotopoulou et al 2018). However, in line with our findings regarding STRYDE, these authors also noted biological material within PRECICE nails, while internal corrosion was confined to the early versions.…”

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

“…These findings are congruent with the visual assessment of the PRECICE nail found in a previous study. 33 This is the first study that is attempting to quantify the extent of wear sustained on the telescopic component of PRECICE nails and identify possible factors that contribute to an increase in wear. Aside from the difference in design, further implant factors such as implant diameter did not affect wear (p = 0.056).…”

Purpose: We aimed to understand material loss from the telescopic component of PRECICE nails, which are used for distraction osteogenesis of the femur or tibia. We also aimed to identify any correlation between implant performance and patient factors.Methods: This retrieval study involved 11 magnetically controlled intramedullary nails from 9 patients who had achieved the targeted leg length. All the nails were assessed macroscopically and microscopically for material loss. All implants were radiographed to assess the internal mechanism. A Talyrond 365 (Taylor Hobson, Leicester, UK), roundness measuring machine was used to generate 3-dimensional surface maps of the telescopic to allow for measurement of material loss.Results: Visual assessment of all the nails showed evidence of material loss from the telescopic component. The radiographs revealed that all the nails had intact internal mechanism and no evidence of fractured pins. The roundness measuring machine showed that the quantity of material loss was lowest in the latest design of the PRECICE nail. There was no significant correlation between material loss and the two patient factors (duration of the lengthening phase, the time of implantation) included in this study.Conclusion: This study is the first to investigate the performance of the three different designs of the PRECICE system with a focus on material loss. We found that the latest design had the best implant performance. We are confident of the continued success of the PRECIEC system and reassure surgeons and patients that they are unlikely to encounter
