Abstract

Femoroacetabular impingement (FAI) has gained much attention over the past decade. It has been associated with hip and groin pain, decreased hip function and can ultimately lead to osteoarthritis.1 A recent consensus meeting defined FAI as “a clinical entity in which a pathological mechanical process causes hip pain when morphological abnormalities of the acetabulum and/or femur, combined with vigorous hip motion (especially at the extremes), lead to repetitive collisions that damage the soft-tissue structures within the joint itself.”2 However, there is a lack of clarity regarding the definition of morphological abnormalities. The presence of a cam or pincer deformity is a prerequisite for defining cam-type and pincer-type of FAI. Although an obvious cam deformity is not difficult to recognise, there may be subtle differences between normal and abnormal bony morphology. This is illustrated by a study showing poor correlation between the subjective assessment of the head–neck junction and objective measures.3 Poor reliability of radiologists and orthopaedic surgeons in quantifying morphological abnormalities has also been demonstrated.4 Objective methods to quantify a cam deformity are, therefore, preferable. Several …

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
