Avulsion fracture – hip/pelvis
What is a pelvic or hip avulsion fracture?
A pelvic avulsion fracture occurs when a very small part of the pelvis or hip bone is pulled too forcefully by the muscle and breaks away. Due to the structure of their growing bones, this type of injury is more likely to occur in teenagers than in younger children or adults.
This can result in a sharp pop followed by pain around the hips or pelvis which can then make it sore to walk for a few days.
This injury often happens in children who are growing quickly and have tight muscles around their hips and legs.
The injured area is normally sore for 1-2 weeks but with rest and gentle stretching the pain usually settles within a few weeks and it is safe to return to normal sports and activities as your pain settles and you feel able to do so.

What is the best treatment?
Immediately after an avulsion fracture in the hip, it is important to manage it correctly, it is very important to keep your leg moving as best as possible as well as try to reduce the pain and swelling.
The current guidance on treating a minor avulsion fracture is to follow the PEACE and LOVE principles.
PEACE
- Protection – Avoid activities and movements that increase pain during the first few days after injury.
- Elevation – Raise the injured limb higher than the heart as often as possible.
- Avoid Anti-Inflammatories – Avoid taking anti-inflammatory medications as they reduce tissue healing. Avoid icing.
- Compression – Use elastic bandage or taping to reduce swelling.
- Education – Your body knows best. Avoid unnecessary passive treatments and medical investigations and let nature play its role.
LOVE
- Load – Let pain guide your gradual return to normal activities. Your body will tell you when it is safe to increase the load.
- Optimism – Condition your brain for optimal recovery by being confident and positive.
- Vascularisation – Choose pain-free cardiovascular activities to increase blood flow to repairing tissues.
- Exercise – Restore mobility, strength and proprioception by adopting an active approach to recovery.
What if I need pain relief?
To manage your pain and keep your hip moving it is advised that you initially take regular simple pain relief. This can be bought over the counter from a pharmacist.
If you have any allergies or conditions which affect the use of pain relief or any questions or concerns please seek advice from your GP or a pharmacist.
Rehabilitation and recovery
If you follow this advice leaflet your injury should take around 6-8 weeks to heal.
However, everyone recovers from injuries at different rates and it is dependent on the severity of the injury, the soft tissue that was involved and the presence of any other medical problems.
If you follow this advice leaflet your injury should take around 8-10 weeks to heal.

0-2 weeks after injury
If you have been given crutches in the Emergency Department (ED) use these as required in the early stages.
You should attempt to wean off them as soon as possible and resume normal activities as soon as your hip feels comfortable and you feel able to.
It is safe to move and put as much weight through your leg as soon as you feel able to both with or without crutches.
2-4 weeks after injury
Start to try and add in some gentle cardiovascular activity like cycling or swimming as you feel able to as well as keeping other parts of your body moving like doing core stability exercises or upper body exercises if you have access to a gym.
If after 2-3 weeks, you are still struggling with any of the following, please contact the physiotherapy department on 0131 3121079 and ask to make a self-referral:
- Still having difficulty fully bending and straightening your hip and knee
- Are unable to put all of your weight through your leg without crutches
4+ weeks after injury
If you have followed all of the exercises within this guide and gradually built up your activity levels it is safe to start re-introducing more challenging activities such as gentle running and jumping.
You can also start adding in more sport-specific activities as you feel able to and make a gradual return to training.
Remember to always be guided by your hip – a little bit of pain that goes away quickly is normally nothing to worry about but if you are experiencing high levels of pain that don’t settle quickly you should contact the physiotherapy department on 0131 3121079.

Return to sports and activity
Once your hip is no longer painful and the movement is much better you can gradually return to gentle activities.
As your leg or hip continues to feel better you can gradually return to your usual activities ensuring you warm up and cool down fully.
If you feel as though you are able to, you do not have to wait for the go-ahead from a health professional to return to your normal activities.
Do I require further treatment?
If you have regained full movement at your hip, are able to walk and run pain-free and have been able to return to your normal sports and activities you don’t need any further assessment or treatment.
If you do have any concerns or are struggling to return to your normal activities please call the physiotherapy department to make a self-referral.
