What It Is

A bone fracture in the ankle is a problem for anyone who sustains it. As well as being painful, the recovery process can be lengthy and limit mobility.

What Causes Weber A, B, and C Fractures?

The ankles are among the most important joints in the body. They carry all of your body weight whenever you stand, walk, jog, skip or run.

Weber fractures are usually caused by the ankle rolling or twisting, for example when slipping, tripping or falling (Northern Lincolnshire and Goole NHS Foundation Trust, n.d.; Smithuis, 2012).

Weber Fracture Anatomy

A Weber fracture is a break at the bottom of the fibula, the thinner bone on the outside of your lower leg. The lower end of this bone is known as the lateral malleolus – the bony bump on the outside of the ankle. Whether a fracture is Weber type A, B or C depends on exactly where the break is on the lower fibula, compared with the syndesmosis – the strong ligaments that hold the lower ends of the two shin bones together (Smithuis, 2012).

Getting Diagnosed

Ankle fractures are diagnosed by examination and X-ray. When examining an ankle fracture, it is important to work out how much the ligaments are injured and whether the joint is stable.

The Weber classification is based on the level of the fibula fracture compared with the syndesmosis, which helps hold the ankle joint together (Smithuis, 2012).

Establishing the extent of the injury helps doctors recognise injuries early and detect fractures that may not be obvious on a brief examination.

Weber A – caused by an inward (adduction) force on a foot turned inwards (supinated); the fracture is below the level of the syndesmosis (Smithuis, 2012).

Weber B – caused by an outward-twisting (exorotation) force on a supinated foot; the fracture is at the level of the syndesmosis (Smithuis, 2012).

Weber C – caused by an outward-twisting force on a foot turned outwards (pronated); the fracture is above the level of the syndesmosis, and usually involves injury to the syndesmosis and an unstable ankle (Smithuis, 2012).
