If carpal instability is due to an architectural bone alteration, the bone defect should be corrected by osteotomies, bone wedge grafts, or osteosynthesis. Treatment for scapholunate instability can be treated by following the following guidelines: Treatment for a scaphoid bone fracture involves putting a cast on the hand to immobilise the wrist, although in some cases, surgery may be resorted to. It causes bone ischaemia and necrosis without a previous fracture. Preiser disease is a rare condition which is also known as idiopathic avascular necrosis of the scaphoid. When this happens, the gap between the scaphoid and the lunate bones increases. A scaphoid fracture can be difficult to diagnose as it is often confused with a wrist sprain.Īnother condition that affects the scaphoid is scapholunate instability, which occurs when the scapholunate ligament (that connects the scaphoid with the lunate bone) and other surrounding ligaments rupture. Sometimes, a scaphoid fracture only causes mild discomfort and pain in the area. Any pressure on the bone can cause intense pain. Pain and wrist swelling are the most common symptoms. Fractures tend to happen due to falling on an extended hand or due to a bad stretch. The scaphoid is a link between the two carpal bone rows.Ī hand scaphoid fracture is one of the most common injuries, due to its proximity to the two rows of carpal bones. Along with the lunate, it articulates with the radius and ulna to form the main bones involved in wrist movement.

The carpal bones are a unit that provide bony structure to the hand. The scaphoid is one of the bones that is injured the most. It is in the thumb area and is the first bone of the first row of the carpus. The scaphoid bone is one of the carpal bones in the hand.
