Total Hip Arthroplasty for Bilateral Femoral Neck Stress Fracture:A Case Report and Review of the Literature

Femoral neck stress fractures (FNSFs) can be treated conservatively or surgically, depending on initial displacement and patientcondition. Surgical treatment options include internal fixation, with or without valgus osteotomy or hip arthroplasty, either hemior total. (e latter is mainly considered when initial treatment fails. A review of the literature shows that total hip arthroplasty(THA) is only considered as primary treatment in displaced fractures (type 3) in low-demand patients. We present a case ofsuccessive bilateral FNSF in a young active patient, where a THA was performed on one side, after failed internal fixation, andwhere it was chosen as primary treatment on the other side after failed conservative treatment.
