A Study of Management of Subtrochanteric Fractures Treated by Proximal Femoral Nail - A Prospective Study

BACKGROUND The proximal femur nail (PFN) is one of many intramedullary nails that have been designed for the early mobilisation and secure fixation of subtrochanteric fractures. METHODS We conducted a prospective study at our institute between November 2018 and November 2020 on a hundred patients who had high subtrochanteric fractures and were treated with proximal femoral nailing. Ninety-five patients had fracture fragments reduced to within a few millimetres of their anatomical size, whereas five needed limited open reduction. RESULTS In the current study, nine (7.76%) of the cases had superficial infections; no deep infections were observed. In five cases (5.76%), we found an anti-rotational screw cut-off. Three (4.75 percent) of the patients had shaft fractures with nail breaking. In the present series, the mean modified Harris Hip Score was 81.24, ranging from 100 to 29. Regardless of fracture kind, all of the patients between the ages of 20 and 30 achieved good results (80.77 percent) in this study. Patients in the older age group had comparatively bad results (19.33%), with 50 percent (5) having poor results and five (50%) having good to fair results. CONCLUSIONS Patients in the older age groups did not have a good outcome in this series. These findings suggest that to reduce problems, a meticulous surgical technique and adjustments tailored to the individual fracture pattern are required. The advantages of the high rotational stability and unreamed insertion method of the head-neck fragment, as well as the potential of static or dynamic distal locking, are emphasized in osteosynthesis of the proximal femoral nail.
