A. The plain radiograph of the right wrist demonstrating type III complete fusion of lunotriquetral bones B. The posteroanterior radiograph of the right wrist revealing complete osseous coalition between the LT bones (Minnaar Type III) of the proximal row of the carpal bone (arrow) C. The lateral radiograph of the right wrist of a male patient showing type III complete fusion of the lunotriquetral bones of the proximal row of the carpal bone (*) R: Radius, U: Ulna, S: Scaphoid bone, L-T: Lunotriquetral fusion, P: Psiform bone.

Lateral scout ST:1 mm, W 400/ C 40, zoom factor 1,14 ma 10 KV 120 (Fig. 1). The AP, lateral radiographs and CT exhibited fusion of the lunate and triquetral bones of the wrist (type III lunotriquetral fusion, complete osseous fusion) (Fig. 1). On further investigations, a plain AP radiograph of the right wrist presented a right-sided unilateral type III osseous coalition between the lunate and triquetrum bones, as shown in Fig. 1.
Asymptomatic variant. Axial CT (2 mm) A. The lunotriquetral (arrows) type III was found during axial CT examination after major trauma B. The axial CT of the left wrist.
