Multicenter StudyAugmentation plating leaving the nail in situ is an excellent option for treating femoral shaft nonunion after IM nailing: a multicentre study.
In recent years, plate augmentation over a retained intramedullary (IM) nail has been shown to be an effective option for managing femur fracture nonunions because it improves the biomechanical environment of the fracture site without causing additional biological damage. In the current study, we present outcome data from 22 consecutive patients treated with plate augmentation for femoral shaft nonunion leaving the nail in situ. ⋯ Augmentation plating leaving the nail in situ is an excellent option for treating femoral shaft nonunion after IM nailing, with a high union rate and few complications. We believe the technique should gradually replace exchange nailing as the standard of care for the majority of femoral shaft nonunions that occur after IM nailing.

Multicenter StudyNailing the fibula: alternative or standard treatment for lateral malleolar fracture fixation? A broken paradigm.
Despite the fact that open reduction and internal fixation with a plate, either non-locked or locked, is the standard of care for managing lateral malleolus fractures, intramedullary (IM) fixation of the fibula has been recently introduced as an alternative, mainly for some potential complicated situations. We hypothesized that almost all patterns of distal fibula fracture can be safely fixed with an IM device, with the potential benefit of providing biomechanical efficiency, but using a soft-tissue friendly implant. Here, we present a multicenter case series based on a proposed algorithm. ⋯ In this multicenter case series, intramedullary fixation for the lateral malleolus fracture presented itself as a viable and safe option for the treatment of almost all patterns of fibula fracture in adults. Overall, we were able to demonstrate the potential indications of the proposed algorithm for the choice of IM implant for the lateral malleolus fracture in terms of the Lauge-Hansen staged classification.

Limb Lengthening for Congenital Deficiencies Using External Fixation Combined With Flexible Intramedullary Nailing: A Multicenter Study.
Hydroxyapatite (HA) coated flexible intramedullary nailing (FIN) stimulates osteogenic activity. The role of HA-coated intramedullary nails remains unclear in normal bone lengthening. The goal of this study was to quantify the influence of FIN on the External Fixation Index (EFI) in patients with congenital lower limb discrepancy. ⋯ Both Ti-nail and HA-coated nail lengthening provide good and excellent outcomes for femoral and tibial monosegmental lengthening procedures and ensure reduced EFI. In congenital disorders which were not associated with abnormal bone, there are no differences with regard to EFI using HA-coated or non-HA-coated FIN. The ratio of "elastic Ti-nail diameter/medullary canal diameter at narrowest site" <0.15 seems to be associated with higher risk of fracture at the lengthening site after frame removal.

Early versus delayed weight bearing after intramedullary nailing for tibial shaft fracture: A multicenter, propensity score-matched study, the TRON study.
The purpose of this multicenter study was to assess the differences in the rates of implant failure and bone union by X-ray examination, and walking ability between an early weight-bearing group (EWB) and a non-weight-bearing group (NWB) following treatment with intramedullary nailing (IMN) for tibial shaft fractures with a propensity score-matching method. ⋯ There were no statistically significant differences in the rate of implant failure, the rates of the bone union at six months and one year after surgery, and walking ability between the EWB group and NWB group. We suggest that instruction in early weight-bearing after IMN nailing for tibial shaft fracture may not be harmful.
