Autogenous fibula graft and cannulated screw fixation to cephalic cut out after DHS fixation: a retrospective study

BACKGROUND: This study aimed to explore the effect of the treatment through autologous fibula graft and hollow needle fixation to treat femoral head cutting after dynamic hip screw (DHS) fixation. METHODS: A total of 41 patients were admitted to the department of orthopedic trauma and received DHS fixation. Preoperative and postoperative harris score of hip function, limb shortening length and collodiaphysial angle between operation group (n = 11) and non-operation group (n = 13) were compared. RESULTS: There was no difference between the two groups before surgery (P > 0.05). There was a difference between the preoperative and postoperative in the operation group (P < 0.05). The excellent and good rate of the hip function score in patients 6 months after the operation was 55.6%. In the operation group, the hip function score increased after surgery (P < 0.001). Except for two groups of patients before operation, there was a difference in the limb shortening length and collodiaphysial angle between the operation group and non-operation group in other time points after surgery (P < 0.001). CONCLUSION: The application of the autogenous fibula graft and hollow nail fixation was effective in treating femoral head cutting after DHS fixation, and patients’ subjective evaluation and objective indicators’ outcomes of follow up were satisfactory, which was worthy of clinical application.
