Everything You Need to Know About a Femoral Stress Fracture

What is a Femoral Stress Fracture?

A femoral stress fracture is a tiny crack in the femur (thigh bone) caused by repeated stress or overuse, rather than a single traumatic event. It’s more common in runners, military recruits, and athletes who do lots of repetitive loading, especially if their training ramps up too quickly. The pain tends to build up gradually over time.

An analogy…

Imagine bending a paperclip back and forth, if you keep repeating the motion without giving it time to rest, it starts to crack. That’s what happens to bone under repetitive stress without recovery time.

What are other names that a femoral stress fracture can be called?

Stress Fracture of the Femur

What causes a femoral stress fracture?

The femur bears a lot of force with every step, especially during high-impact activities like running or jumping. If the muscles and bones are overloaded repeatedly, and recovery isn’t adequate, the bone begins to fatigue and develop small cracks. These are called stress fractures. If left untreated, they can worsen and become full fractures.

What are the signs and symptoms of a femoral stress fracture?

Dull, aching pain in the groin or upper thigh
Pain that worsens with running or weight-bearing, and eases with rest
Pain that gradually increases over days or weeks
Pain with hopping or single-leg loading
In more severe cases, night pain or pain at rest
Limping or altered walking in advanced stages

What tests are used to diagnose a femoral stress fracture?

Palpation: May reveal deep tenderness in the groin or upper thigh.

Single-leg hop or fulcrum test: Often reproduces pain.

How long does a femoral stress fracture take to heal?

Early-stage femoral stress fractures may heal in 6 to 8 weeks. Moderate to advanced stress fractures may take 10 to 12 weeks. Return to sport typically takes 12+ weeks, depending on healing and strength recovery.

How does a femoral shaft fracture happen?

Sudden increase in training volume or intensity
High-impact repetitive activity
Poor nutrition, low Vitamin D or calcium
Weak glutes or core, leading to poor load distribution
Improper footwear or hard training surfaces

What treatment can help a femoral stress fracture?

Complete rest from impact activity
Gradual weight-bearing progression once cleared by a practitioner
Strength training for glutes, core, and hip stabilisers
Nutritional support to address any bone health deficiencies
Biomechanical retraining

What exercises or stretches can I do for a femoral stress fracture?

Non-weight-bearing strength exercises
Glute activation drills
Swimming or stationary bike
Balance and proprioception exercises
Gradual return-to-run program over 4–8 weeks

What products can help with a femoral stress fracture?

Step-ups

Step ups strengthen the muscles of the hip and thigh, and can help to improve your ability to walk and climb stairs.
Stand at the bottom of a step with the bannister, a hand rail or a chair nearby for support.
Place your right foot on the step, move up and then step up with the left leg.
Step back down with the right leg, followed by the left.
Repeat this exercise, then change to lead with the left leg and repeat the sequence, continue on for the required amount of time.

Sit to stand from chair

Start in a seated position.
Bring your bottom to the edge of the chair with your feet back underneath you.
Try to do this exercise without using your hands.
Stand up until you are completely upright and then gradually sit back down.
Control this movement and then repeat.
If you do need to use your hands, try to limit their use as much as you comfortably can.

Standing hip abduction

Stand straight, holding a chair or table for balance.
Keeping your affected leg straight, slowly move it out to the side.
Control the leg as you bring it back in to the starting position, and then repeat the movement.
Make sure you do not lean your body or hitch your hip up as you move your leg.

Bridging

Lie on your back with your knees bent and your feet flat on the floor.
Tighten your buttock muscles and lift your hips up off the floor.
Make sure you keep your hips up and level throughout the movement.
Slowly lower your buttocks and hips back down, and repeat the exercise.
