Definition[edit | edit source]
Fulcrum Test is a clinical test used to diagnose Femoral Shaft Stress Fracture. Stress fractures of the femoral shaft are uncommon and mostly occur at the proximal third of the femur[1]
Clinically Relevant Anatomy[edit | edit source]
The Femur is the longest bone in the body and extends from the hip to the knee.
The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and kneecap, forming the knee joint. It serves as a site of origin and insertion for many muscles and ligaments.

Purpose[edit | edit source]
The fulcrum test is used to aid the diagnosis of femoral shaft stress fractures.
If the clinical test is positive during the physical examination, the diagnosis must still be confirmed by a bone scan or a Magnetic Resonance Imaging scan(MRI)[2].
Technique[edit | edit source]
The patient is seated on the examination table with his lower legs dangling. The examiner places one of his arms under the symptomatic thigh. The examiner’s arm is used as a fulcrum under the thigh and is moved from distal to proximal thigh as gentle pressure is applied to the dorsum of the knee with the opposite hand. At the point of the fulcrum under the stress fracture, gentle pressure on the knee produced increased discomfort that was often described as sharp pain and accompanied by apprehension. The contralateral leg served as a negative control. The level at which the fulcrum test is positive has always corresponded to the site of the stress fracture in the femoral shaft as seen in a scintigram or radiograph. [3]

Clinical Relevance[edit | edit source]
Femoral shaft stress injuries can be managed conventionally with rest, activity modification, and protected weight-bearing. If the patient has low bone mineral density, is older than 60 years old, or has fracture completion or displacement, Open reduction and internal fixation with an intramedullary nail is indicated. The duration of treatment varies with individual patients, the period of relative rest will last 12 weeks. Compliance is critical to the success of the treatment, as well as good cooperation between the treating physician and patient.[4]
