A scaphoid fracture is a break of the scaphoid bone in the wrist. [1] Symptoms generally includes pain at the base of the thumb which is worse with use of the hand. [ 2 ] The anatomic snuffbox is generally tender and swelling may occur. [ 2 ]
In metaphyseal areas, delayed signs of fracture include a band of sclerosis perpendicular to the trabeculae, while diaphyseal fractures may present as periosteal thickening. [1] Digital radiography known as tomosynthesis has been shown to be superior to conventional radiographs in the detection of occult fracture of the scaphoid.
Scapholunate advanced collapse is the most common form, followed by scaphoid non-union advanced collapse (SNAC). [3] Other post-traumatic causes such as intra-articular fractures of the distal radius or ulna can also lead to wrist osteoarthritis, but are less common.
Preiser disease, or avascular necrosis of the scaphoid, is a rare condition where ischemia and necrosis of the scaphoid bone occurs without previous fracture.It is thought to be caused by repetitive microtrauma or side effects of drugs (e.g., steroids or chemotherapy) in conjunction with existing defective vascular supply to the proximal pole of the scaphoid.
Scaphoid fracture, distal radial fractures, avascular necrosis of the scaphoid, gout, pseudogout, rheumatoid arthritis, Kienbock disease, lunate fracture vs dislocation dorsal intercalated segmental instability: Treatment: Non-surgical and surgical (fusion, joint replacement)
In medicine, not otherwise specified (NOS) is a subcategory in systems of disease/disorder classification such as ICD-9, ICD-10, or DSM-IV. It is generally used to note the presence of an illness where the symptoms presented were sufficient to make a general diagnosis , but where a specific diagnosis was not made.
Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone.
Scapular fracture is present in about 1% of cases of blunt trauma [1] and 3–5% of shoulder injuries. [4] An estimated 0.4–1% of bone fractures are scapular fractures. [2] The injury is associated with other injuries 80–90% of the time. [1] Scapular fracture is associated with pulmonary contusion more than 50% of the time. [8]
