Abstract

Femoroacetabular impingiment (FAI) can cause arthrosis and pain in the hip joint atan early age. FAI can be seen solo in the femur neck or solo in the femoral head due tomorphological changes (Cam-type FAI), or only in the acetabulum femur head excessive covering (pincer type FAI) or in combination of both (mixt type FAI). Diagnosisis made by clinical and radiological examinations. Alpha angle (AA) and femoral head-neck offset (FHNO) are measured for radiological diagnosis of cam-type FAI on computed tomography (CT). However, in various studies showed incerase in AA and decrease in FHNO at asymptomatic hips, as in cam-type deformities. In this study, we aimed to examine the AA and the FHNO values in the Turkish society by examining theCT images of individuals who did not have any complaints from the hip joint.Hip joints of abdominal CT examinations were investigated for this purpose. In all hips,33 (14.4%) had high AA and 15 (6.5%) low FHNO in the hip joint. As a result, it is obser-ved in the society that there may be asymptomatic individuals who are compatible with ra-diologically cam-type FAI.

Femoroasetabular impingiment (FAİ) erken yaşta kalça ekleminde artroz ve ağrıyaneden olabilmektedir. FAİ sadece femur boynunda ve femur başındaki morfolojik değişikliklere bağlı (cam tipi FAİ) olabileceği gibi asetabulumun femur başını aşırı örtmesi (pincer tipi FAİ) ile veya her ikisinin kombinasyonu şeklinde (mixt tip FAİ) görüle-bilir. Tanısı klinik ve radyolojik tetkiklerle konulur. Cam tipi FAİ’nin radyolojik tanısıiçin bilgisayarlı tomoğrafide (BT) alfa açısı (AA) ve femur baş-boyun offseti (FBBO)ölçülür. Ancak çeşitli çalışmalarda asemptomatik kalçalarda cam tipi deformitelerde olduğu gibi AA’nda yükseklik ve FBBO’da düşüklük olduğu gösterilmiştir. Bizde bu ça-lışmada kalça ekleminden herhangi bir şikayeti olmayan bireylerde çekilmiş BT’leri inceleyerek Türk toplumundaki AA ve FBBO değerlerini incelemeyi hedefledik. Bu amaçla abdominal BT tetkiki yapılmış hastaların kalça eklemleri incelenmiştir.Tüm kalçalarda 33 (%14.4) kalça ekleminde yüksek AA, 15 (%6.5) kalça ekleminde dü-şük FBBO bulunmuştur. Sonuç olarak toplumda radyolojik olarak cam tipi FAİ ile uyumlu ancak asemptomatik bireylerin olabileceği gözlenmiştir.
