Canadian Orthopaedic Limb Lengthening Association (COLLA)


Calling All Limb Lengthening and Deformity Correction Surgeons!

Feel like your subspecialty is quite different from your colleagues’?

Want to find colleagues with whom you can discuss cases or research? Want your field to be validated as a distinct subspecialty within the COA and start seeing lectures on topics pertaining to limb lengthening and deformity correction?

Whether you are a paediatric or an adult limb lengthening and deformity correction surgeon, COLLA is for you! Our goal is to establish a collaborative group of colleagues from across Canada who are interested or currently have a practice in limb lengthening and deformity correction
