Abstract/OtherAbstract:
INTRODUCTION: Pseudarthrosis of femoral neck stress fractures in young adults are associated with a high incidence of complications and revision surgery. The majority are treated urgently with closed reduction and internal fixation.
PRESENTATION OF CASE: We describe a displaced tension-type femoral neck fatigue fracture presenting late. Pseudarthrosis formation prior to surgery resulted in resorption and shortening of the femoral neck. Open reduction and internal fixation was performed, with adjuvant recombinant human bone morphogenic protein-7 therapy. Radiological union was achieved by twelve weeks and by one year the patient was asymptomatic.
DISCUSSION: Reports of successful management of femoral neck fatigue fracture non-unions are rare. Meyer's muscle pedicle graft, valgus subtrochanteric osteotomy, and cannulated screw fixation with autologous iliac crest bone graftare alternative procedures.
CONCLUSION: This extremely rare fracture type merits open reduction to enable accurate fracture reduction. Supplementing sliding hip screw fixation with an orthobiological agent was successful in this challenging situation.
