Analysis of triquetral-lunate fusion

Analysis of triquetral-lunate fusion.

Fusion of the centers of the triquetral and lunate (the 0s lunatotriquetrum) was observed in 1.6% of 7,543 subjects primarily of African origin as compared with 0.1% of 11,663 persons of European origin. The fusion was twice as common in females as in males, multifactorial inheritance was suggested in the lineages studied, and a possible selective disadvantage was postulated after comparison wi...

A note on the fusion of the lunate and triquetral centers.

Congenital Fusion of the Lunate

Congenital fusion of the lunate [semilunar] bone with the triquetral [cuneiform] is an abnormality which has been considered to be rare, even in negroes, who have been regarded as specially subject (Shanks 1950). Smitham (1948) estimated its incidence in a series of West African natives to be one in seventeen (5’9 per cent), and if his experience is typical it is certainly much commoner in some...

Impaction-fracture of the capitate and lunate: a case report.

We report a 15-year-old girl who underwent a mid-carpal fusion for undiagnosed impaction-fractures of the capitate, lunate, and triquetrum after a fall on her outstretched left hand in a dorsiflexed and radially deviated position. The joint was dis-impacted, and the height of the lunate was restored using a cortical bone graft. The damaged proximal capitate articular surface was decorticated to...

Lunate dislocation.

Carpal dislocations are wrist injuries and Lunate dislocation is its severe form. Lunate and perilunate dislocations are uncommon. These injuries have significant clinical impact on the patient but are easily missed and lead to potentially devastating effect if mismanaged. This case report outlines the important clinical aspects and management of Lunate dislocation.
