  • Hamstring Muscle Strain

  • Adductor (Groin) Muscle Strain

  • Hip Flexor Muscle Strain

Sprain

• Injury to a joint or ligament

• Common THG Sprains

  • Hip Joint Sprain/Dislocation

  • Hip Labral Tear

Stress

• Too much chronic force

• Common THG Stress injuries

  • Stress Fractures

  • Osteitis Pubis

  • Athletic Pubalgia

Developmental Injuries
