We know that registering for websites can be a pain and often puts people off. That is why we have kept the majority of the website freely accessible without logging in. However, some of our more sensitive pages, for example videos featuring children, can only be viewed by logging in. This is to ensure the images and videos are only used for clinical and educational purposes. We hope this does not prevent you using the rest of the website.

We are sorry for the inconvenience. Did you try registering with a hotmail / yahoo/ gmail etc address? If so, please try again using your work or university email address. The purpose of registering is to allow us to manage who is able to access the more sensitive pages such as images and videos of children and to do this we require users to use their academic or healthcare email account. If you do not have an academic or healthcare email account but would like access for clinical or educational purposes please email providing verifiable information about your work and we will endeavour to help. You can, of course, continue to access most of the website that is in the public domain without being logged in. 





This has most likely happened because your email address is not on our list of organisations and institutions, which we have recognised as legitimate clinical organisations. We’re sorry for the inconvenience. We are constantly building the list up so please email us at stating which institution you work for / are registered with or if you have another work email address try that instead. Do not forget you can still access most of the site without being logged in. 

Click the ‘forgotten username or password’ button on the homepage and a new password will be emailed to the email address with which you registered.

If you think you’ve found an omission or mistake, or if you have a suggestion as to how PMM could be even more useful for you, please do get in touch via the contact us page, or alternatively email

Sorry we cannot reply to requests for clinical advice. Please see our referral pages for advice regarding who to refer to in different clinical scenarios and our pages on the paediatric musculoskeletal multidisciplinary team (MSK MDT) to help you decide which professionals might be able to help you, depending on your local services.

The website is hosted by Newcastle University and has ethical approval as an educational resource. 

pmm and pmm-nursing have been developed by a collaborative team in Newcastle upon Tyne, UK led by Professor Helen Foster at Newcastle University. We have developed the content from our research with medical students, general practitioners, nursing students, nurses and specialists to find out what health care professionals need to know.

pmm and pmm-nursing provide the essentials of information, informed through our research and we signpost to more information as needed.

Future iterations will include further contributions from around the world.

We welcome feedback so please do contact us.

The project was funded originally from an unrestricted educational bursary from Pfizer. Further bursaries were obtained from BioMarin and Sobi. These companies had no role in deciding what content should be included.

The platform was developed by Boxmodel Digital

The branding and design were created by everything d.fferent
