Vascularized Bone Graft for Scaphoid Nonunions
Techniques in Hand & Upper Extremity Surgery, 2004Scaphoid fracture nonunion remains a challenging problem that may persist despite traditional methods of bone grafting and internal fixation. The alteration of wrist mechanics created by nonunion as well as the development of avascular necrosis leads to degenerative change of the radiocarpal joint accompanied by loss of motion and pain.

Annales de radiologie, 1993
The scaphoid is the most important carpal bone due to the frequency of its pathological involvement. Two points of radiological anatomy are stressed: the presence of the scaphoid tubercle whose projection gives rise to the scaphoid ring, the solid radio-capitatum ligament which bridges the scaphoid.

Bone Mineral Density in the Scaphoid
Plastic SurgeryIntroduction: The scaphoid bone is essential for wrist stability and movement. While fractures commonly occur at the scaphoid's waist, those at the proximal pole, though rarer, tend to result in nonunion, potentially linked to variations in bone mineral density (BMD).

Isotope bone imaging in suspected scaphoid trauma
The British Journal of Radiology, 1981The unreliability of radiological examination in excluding or confirming a suspected scaphoid fracture after carpal trauma is a well-recognised diagnostic problem. This paper explores the role of isotope bone imaging (IBI) in the early identification of carpal bone injury.

Non-scaphoid Carpal Bone Fractures
2017The scaphoid bone accounts for approximately 70% of all carpal bone fractures. The other 30% of these fractures are divided among the remaining seven carpal bones. Knowledge of these relatively rare carpus fractures is imperative to make correct diagnoses, address concomitant injuries, and develop appropriate treatment plans.

Rapid prototyping of scaphoid and lunate bones
Biotechnology Journal, 2009AbstractIn this study, a novel rapid prototyping technology was used to fabricate scaphoid and lunate bone prostheses, two carpal bones that are prone to avascular necrosis. Carpal prostheses were fabricated with an Envisiontec Perfactory® SXGA stereolithography system using Envisiontec eShell 200 photocurable polymer.

Dysplasia epiphysealis hemimelica of the scaphoid bone
European Radiology, 1999We report a rare case of dysplasia epiphysealis hemimelica (DEH) in the wrist of a 7-year-old boy. Clinical, radiological and histopathological manifestations are discussed. The correct diagnosis of DEH, however, was made by the confrontation of the radiological and pathological data.

Cylinder-Shaped Bone Graft for Scaphoid Nonunion
The Journal of Hand Surgery (Asian-Pacific Volume), 2018Background: Wedge-shaped bone grafts that are internally fixed by a Herbert-type screw are a well-established surgical treatment for scaphoid nonunion. A procedure using cylinder-shaped bone grafts was also reported, but preoperative wrist functions were not assessed.
