Abstract
Femoral neck stress fracture is rare. We report a case of femoral neck stress fracture in an adult female. A 47-year-old female who works as a caregiver causelessly felt a sudden onset of pain in her left hip joint. She gradually could not walk, so she visited another hospital. Radiographs showed no abnormal findings. Due to continuous hip pain, she visited our hospital after a month. She had pain on motion and tenderness in her hip joint. Radiographs on her left hip joint showed wide spacing, but magnetic resonance(MR) images showed low signal intensity lesion in T1-weighted and high signal intensity lesion in T2-weighted images on the femoral neck. She was diagnosed with stress fracture of the left femoral neck and hospitalized. We performed osteosynthesis under general anesthesia. She was permitted partial weight-bearing after six weeks and full weight-bearing after eight weeks. Six months later, she was able to return to normal life. Femoral neck stress fracture can develop from muscles fatigue around the hip joint. In this case, squatting at work caused the femoral neck stress fracture.
