2024年6月11日 · Acromial types were initially divided into three types (known as the Bigliani classification) 3, to which a fourth has been added 2. These classifications are used as a standardized way of describing the acromion and predicting to a …

Three distinct types of acromion can readily be seen on radiographs, especially on the angled outlet Y view. The type I acromion, which is flat, is the “normal” acromion.

Acromion morphology: Bigliani Classification. Type 1: Flat, 17% Type 2: Curved, 43% Type 3: Hooked, 40%. Top

Three different types of acromion shapes exist. The first of these shapes (and also the most common) is a Type I acromion, which has a relatively flat undersurface. Alternatively, a Type II acromion involves a curved contour whereas a Type III acromion has a more hooked shape.

Bigliani et al 5 classified the shape of the acromion on supraspinatus outlet (or lateral) radiographs into three distinct types: type I represents a flat, type II a curved and type III a hooked undersurface of the acromion (Fig. 1a).

In 1986, Bigliani and colleagues [3] were the first to classify acromial morphology and correlate it with rotator cuff tears. They described three types of acromion: Type I (flat), Type II (curved), and Type III (hooked) (Fig. 1). A Type IV acromion was later described as a convex acromion [28].

The shape of the acromion has been initially divided into 3 types (which was known as the Bigliani classification), to which a fourth has been added: Type 1 acromion: Flat inferiorly; Type 2 acromion: Curved – parallel to the humeral head with convex undersurface – considered commonest type

2011年4月28日 · The acromion fractures can be of many kinds –Type 1, Type 2, Type 3 and the Stress fractures. They may be further sub-divided into Type 1a, 2a, 2b etc. The Types of Acromion are described in detail below. Type 1 Acromion. This …

Type I acromion is characterized by a flat and smooth shape, with a relatively straight or slightly curved undersurface. It has minimal or no protrusion and is considered the most desirable and least associated with shoulder impingement or rotator cuff problems.
