Between 01 April 2008 and 31 March 2018, there were 204 Regular personnel who had a read code for femorocetabular impingement (FAI) entered in to their primary care medical record (Information is recorded into the Defence Medical Information Capability Programme, DMICP, which is a centralised data warehouse of coded information).

Of the 204 personnel, 38 were medically discharged with a principal or contributory cause of a hip disorder between these dates. Of the 38, 14 were medically discharged with a principal or contributory cause of other specified disorders of the hip joint.

It is important to note that causes of medical discharge are recorded using the International Classification of Diseases Version 10 (ICD 10) (ICD 11 was released on 18 June 2018). However, there is no specific ICD 10 code for FAI and, consequently, it is classified within other specified disorders of the hip joint.

What is Femorocetabular Impingement?

Femoroacetabular impingement (FAI) is a condition in which extra bone grows along one or both of the bones that form the hip joint – giving the bones an irregular shape.

Because they do not fit together perfectly, the bones rub against each other during movement.
