Congenital bipartite carpal scaphoid has been reported as an extremely rare congenital anomaly. We report a case of a 47-year-old man who was found with bilateral bipartite carpal scaphoids with no history of injury. Radiographs demonstrated symmetric findings of the distinct bipartition of the scaphoid without obvious degenerative change in both wrists. The patient complained of no other symptoms. The diagnostic differentiation of scaphoid bipartition from the pseudarthrosis of the scaphoid could be important in avoiding unnecessary surgery and inappropriate assessment in compensation cases.

Variations in the development of carpal bones are uncommon, with the scaphoid bone typically forming from the fusion of the os centrale carpi and the radial chondrification center during embryogenesis. A bipartite scaphoid is a rare congenital disorder that occurs when these ossification centers fail to fuse, with a prevalence ranging from 0.1% to 0.

Carpal coalitions are rare wrist anomalies and are most often diagnosed incidentally. Due to their infrequent occurrence, there is a lack of treatment guidelines in the literature. We present a case study of a 13-year-old boy who presented with symptomatic synchondrosis in both scaphoids along with a bilateral osseous coalition between the scaphoid and trapezium bones in combination with bilateral thumb hypoplasia.

We investigated the role of three-dimensional (3-D) CT in the diagnosis and management of four bipartite scaphoids in three patients. We computed the volume ratio, moment of inertia ratio and direction vector from the centroid of the scaphoid to the os centrale carpi. We found that the os centrale carpi was always smaller than the scaphoid and showed an elongated shape in the scaphoid longitudinal axis.

Bilateral bipartite lunate is a very rare congenital anomaly of the lunate. A 36-year-old military European male was referred to our service diagnosed with a lunate fracture. Symptoms began 3 months before our encounter, after falling on his outstretched left hand.
