Abstract
Materials and methods: The study was carried out using an experimental porcine model. Eleven juvenile female porcines were randomized for insertion of a retrograde femoral nail in one limb. The other limb acted as a control. The animals were housed for 8 weeks before the nail was removed and housed for 8 additional weeks, that is, 16 weeks in total. Growth was assessed by interphyseal distance on 3D magnetic resonance imaging (MRI) after 16 weeks and the operated limb was compared to the non-operated limb. Histomorphometric analysis of the physeal canal was performed.
Results: No difference in longitudinal growth was observed when comparing the operated femur to the non-operated femur using MRI after 16 weeks. No osseous tissue crossing the physis was observed on MRI or histology. The empty canal in the physis after nail removal was filled with fibrous tissue 16 weeks after primary surgery.
Conclusion: Growth was not impaired and no bone bridges were seen on MRI or histology 16 weeks after insertion and later removal of the retrograde femoral nail.
Clinical significance: The insertion of a retrograde intramedullary femoral nail centrally through the physis and later removal might be safe, however, long-term follow-up is needed.
Aim and objective: The insertion of an intramedullary nail may be beneficial in certain cases of leg length discrepancy (LLD) in children. However, it is unknown if the physeal injury due to the surgery may cause bone bridge formation and thereby growth arrest after removal. This study aimed to assess longitudinal interphyseal growth 16 weeks after insertion and later removal of a retrograde femoral nail passing through the physis. Moreover, to analyse the tissue forming in the empty physeal canal after removal of the nail.

期刊介绍：
Strategies in Trauma and Limb Reconstruction is dedicated to surgeons, allied medical professionals and researchers in the field of orthopaedics and trauma. The scope of the journal is to discuss the fields of skeletal injury, and the complications thereof, congenital and acquired limb deformities and deficiencies, and orthopaedic-related infection, together with their surgical and non-surgical treatments. The journal publishes original articles, reviews, case reports, descriptions of new or recognised treatment techniques, forum discussions of clinical scenarios and relevant correspondence. It aims to provide a widely accessible source of useful information to practitioners in the field through the problem- or technique-based approach of published articles.
