Lunotriquetral coalition
Updates to Article Attributes
Body
was changed:
Luno-triquetral coalition is the most common type of carpal coalition and represents congenital fusion of the lunate and triquetral bones of the carpus.
Epidemiology
Lunotriquetral is the most common type of carpal coalition with a prevalence of 0.1%. It is more common in females (F:M = 2:1) and African Americans.
Clinical presentation
Whilst osseous coalitions of the lunate and the triquetrum are known to be asymptomatic, fibrocartilage lunate-triquetral coalitions can present an uncommon cause for ulnar-sided wrist pain 3.
Pathology
- coalition may be fibrous, cartilaginous or osseous 5
- commonly bilateral 4
Classification
de Villiers classified lunotriquetral coalition into four types 6:
- incomplete (or fibrocartilage) fusion - resembles a pseudo-arthrosis
- incomplete osseous fusion
- complete osseous fusion
- complete osseous fusion with other carpal abnormalities
Radiographic features
Plain film
- coalition of the lunate and triquetrum
- may be accompanied by widened scapholunate interval 4
Treatment and prognosis
Most commonly an incidental finding. May occasionally be a cause of chronic wrist pain (especially in type 1 and 2 6) and, of course, can be fractured.
