Abstract Purpose To discuss the reason and treatment method of helical blade over-unlocking. Methods The case reported in this paper is that the helical blade cannot be locked due to over-unlocking during the treatment of intertrochanteric fracture with PFNA, which is very rare. We expound why it happens and how to deal with it. Results When the helical blade is over-unlocking, if the aiming arm is not disassembled, you can try to take out the helical blade and fix it again. If the aiming arm has been removed, it is not recommended to remove the helical blade, we suggest that we should consider adding a screw from the lateral wall through the femoral neck for anti-rotation, or you can observe the tail of helical blade and find suitable screw driver to fix it if there is one. Conclusions In order to avoid over-unlocking of the helical blade, intraoperative fluoroscopy should not only pay attention to the position of the helical blade, but also pay more attention to the abnormal shape of the helical blade itself. Once the helical blade is over-unlocking, it needs to be handled in time.

Shaft Angle

We report a case where a one-stage osteotomy and fixation, using a long proximal femoral nail and fibular graft, was performed to correct a severe shepherd's crook deformity (70° varus and 50° retroversion) of the femoral neck with a pathological stress fracture in a patient with fibrous dysplasia. The neck shaft angle was corrected to 125°. At the 57-month follow-up, the patient was free of pain and had no limp or evidence of recurrence.

Neck Fracture

Proximal femoral fractures are a common injury that represents an important cause of hospitalization, morbidity, and mortality in elderly patients. Subcapital femoral neck fracture after fixation of an intertrochanteric fracture with a proximal femoral nail is an extremely rare complication. However, because of the large and steadily increase in the number of patients undergoing to proximal femoral nail fixation in recent years, we believe that the number of these cases could increase over time. We present a 78-year-old woman with a subcapital femoral fracture 11 months after a fixation of intertrochanteric fracture with a proximal femoral nail in the same hip. Five years of follow-up was presented. Also through our case report a review of literature of these rare cases was done, trying to evaluate the associated risk factors, the difficulties in their treatment and the final follow-up of these patients.
