Background Osteogenesis imperfecta is a group of heterogeneous disorders with a common characteristic of congenital bone fragility caused by mutations in genes encoding procollagen type I. (COL1A1 and COL1A2). Objectives This study aims to review the outcomes of the use of different generations of telescopic intramedullary nails in lower limbs for management of children with osteogenesis imperfecta (OI) and evaluate the functional outcomes of them. Patients and Methods Methodology: Criteria for considering studies for this review, types of studies: we will include: case series studies, retrospective cohort studies and we will exclude: case reports, cross sectional studies, non English studies. Search results will be conducted to systematic review management software and manually screened for eligibility to be included. PRISMA flowchart will be produced based on the search results and the inclusion/ exclusion criteria. Results One of the highest complications that have been very challenging for the orthopedic surgeons is migration and displacement of the telescopic intramedullary nails and FassierDuval nail has showed to have the lowest migration and displacement incidence rate (10.3%) which was clinically significant according to our statistics which supports the previous literature. On the other hand according to our statistics we found that there is no statistical significance in the cortical perforation of the telescopic nails between the different generations despite it might have been thought before that Bailey-Dubow nail has higher cortical perforation rate as the P value = 0.413. Post operative fractures and telescopic nail bending have shown no statistical significance according to our statistics which differ from each study when taken separately with P value = 0.252 and P value = 0.059 respectively. For the bending results we think that more studies are needed to increase the number of patients as it might show statistical significance according to its P value. Conclusion Fassier-Duval telescopic nail has good outcomes with the least complication rates and a promising generation of telescopic nail but needs a multicenter randomized control trials to conduct a level I evidence based on meta-analysis.
