Failed Internal Fixation in Bilateral Femoral Neck Stress Fracture Salvaged with Total Hip Arthroplasty: A Report of Two Cases with Literature Review.

Abstract

Bilateral Femoral neck stress fractures (FNSFs) are rare without any underlying metabolic disease or repeated strenuous activities like athletes or military recruits. It constitutes about 5-8% of all stress fractures. Treatment options are still controversial. We report two young women with bilateral simultaneous FNSFs without any metabolic cause, presented to us following failed internal fixation with cancellous screws and neck resorption salvaged with total hip arthroplasty. Compression type stress fracture healed in the final follow-up on the other side.
