Broken scaphoid11/16/2023 More severe arthritis can occur when the scaphoid does not heal giving significant pain. Very mild arthritis is often seen on X-rays following scaphoid fractures, but symptoms from this are unusual. AVN has a strong association with smoking.Īrthritis – The term arthritis is used when the normal joint lining (articular cartilage) becomes damaged or worn.Īrticular cartilage is the smooth, white tissue lining the ends of bones where they form joints, allowing the bones to glide over each other with very little friction. The scaphoid usually does not heal, and surgery may be recommended when this happens. Surgery is then usually recommended, although a small number of patients still have long term symptoms following surgery for non-union of the scaphoid.Īvascular Necrosis – Avascular necrosis or AVN is the name given when the blood supply to the scaphoid bone fails. However, pain and loss of function are common if the non-union is unstable. Some non-unions are stable, and although the bone fails to heal, scar tissue still holds the bone ends together, with a good result. Non-union – Unfortunately, the risk of the fracture not healing is around 10-15%. Passing a screw across the fracture turns the injury from an unstable injury into a stable injury, and this gives it a better chance of healing.Īre there any complications of this injury? A wire is passed down the bone across the fracture and a special screw passed over the wire to fix the 2 parts of the bone together. This is sometimes done through a wound of just a few mm, and sometimes a longer scar over the bone is needed. – Surgical Repair (Internal fixation) of the scaphoid. In some circumstances, surgeons may recommend internal fixation of the bone. – Plaster cast / splint. The vast majority of fractures are stable and only require treatment in a cast. If the scaphoid is unstable, it can still be treated in a cast, but the chances of it not healing are higher than if the fracture is stable. There are 2 options for treating these fractures. You should try to stop smoking if you have a scaphoid fracture, in order to allow the best possible chance of healing. Therefore fractures furthest away from the blood supply are less likely to heal and therefore need surgical intervention.ģ) Smoking. There is a strong association between smoking and non-union (failure of healing) of the scaphoid. The near end of the scaphoid therefore has a poor blood supply and a fracture can easily cut it off preventing healing. Blood, which is essential for healing, is supplied from the far end of the scaphoid, and runs back down the bone towards the wrist. A cyst may form at the fracture site as the joint fluid can promote breakdown of bone – the fracture is then unlikely to heal and surgery is often recommended.Ģ) Blood supply to the bone. There are several factors which influence the speed of the bone healing:ġ) Fracture displacement – in an unstable injury the normal lubricating wrist joint fluid can circulate between the gap between the bone ends. the wrist may still be a bit stiff and sore for anything up to to a year.Īround 10%-15% do not heal i.e. Once healed, many scaphoid fractures continue to give nuisance symptoms i.e. This process can take anything from a few weeks up to around 4 or 5 months. The majority ( around 85% – 90%) of scaphoid fractures heal when immobilised in a plaster cast. The wrist pain and swelling usually settle within the first 6-12 weeks. When the scaphoid bone breaks, there is usually pain over the thumb side of the wrist, but often the whole wrist will be involved and may swell up. The bone still moves as one unit.Ģ) Unstable injury. The broken parts of the bone do not move together – a gap between the bone ends which do not line up perfectly is often seen on X-ray. When the scaphoid bone breaks, it can be in one of two ways:ġ) Stable injury. Everything is still in the right place in a stable scaphoid fracture, and the bone simply has a crack going through it which can be difficult to see on Xray.
