Usually due to repetitive abductor muscle contraction
As with all stress fractures can occur in 2 types
1) Insufficiency type (normal physiologic stress on abnormal bone)
2) Fatigue type (abnormal/excessive physiologic stress on normal bone)
2 locations on interest:
1) Compression side (inferior femoral neck)
2) Tension side (superior femoral neck)
History: Insidious onset of groin or lateral hip pain associated with weight bearing
Exam: Antalgic gait, pain with hip log roll and with FABER (hip flexion, Abduction and external rotation test)
Treatment:
Compression side: reduced weight bearing and activity modification
Tension side: Non weight bearing (due to high risk of progression to displacement with limited weight bearing) AND surgical consultation for elective pinning to prevent displacement. If displaced, will require ORIF
