The hooked acromion is an exaggerated form of the curved type (Fig. 2). Although Bigliani et al (1986) maintained that the hooked shape was an inherent property of an individual it is also recognised that the hooking could be exacerbated by secondary degenerative changes (Nicholson et al 1992).

What is a subacromial spur?
