Studies on NP construct for distal femur fractures and non-unions.
| Passias et al. [12] | Retrospective cohort, level-1 trauma center | 8 cases of NP fixation (97 cases in total) | 100% union rate for NP fixation vs. 69% for single fixation group |
| Kanabur et al. [14] | Retrospective study, NP fixation | 8 cases | 100% healing rate, NWB for the first 4 weeks |
| Birjandinejad et al. [15] | Retrospective study on non-unions, 25 femoral non-unions included | 25 femoral non-unions | 100% union rate for femoral non unions, 80% tolerate weight-bearing immediately after fixation |
| Basci et al. [20] | Biomechanical analysis | Biomechanical analysis of NP fixation vs. rIMN vs. LP | NP construct has highest number of cycles to failure vs. LP/rIMN |
| Fontenot et al. [21] | Biomechanical study on 33C fracture model | Biomechanical analysis | NP construct required 1.8 the amount of cycles to failure 100% survivability |
| Liporace et al. [22] | Retrospective NP fixation | 15 cases | 14/15 healing rate, 8/15 lost one level of independence |
NP: nail/plate fixation, NWB: non weight bearing, rIMN: retrograde intramedullary nailing, LP: lateral femoral plate.
