Headless screws are favored for internal fixation in the treatment of displaced or unstable small bone (e.g., Scaphoid) fractures, because they are embedded below the articular surface of the bone, reducing tissue irritation and immobilization. Compression plays an important role in fracture stability, maintaining gap reduction and also accelerating the healing of cancellous bone [1]. There are...

Abstract Bone fracture treatment aims for restoring the function of a broken bone, and scaphoid fracture, conventional cast is an example commonly used treatment. However, due to its downsides, development customized three-dimensional (3D) printed hand getting more attention. It lightweight, easy manage, has good ventilation hygienic properties. Hence, this study fabricate 3D in treating fractu...

BACKGROUND The carpal scaphoid is the most commonly fractured carpal bone in young adults after a fall on an outstretched arm that results in acute dorsal flexion of the wrist. However, stress fractures of the scaphoid are relatively rare. To the best of our knowledge, we describe the first case in the literature of carpal scaphoid stress fracture in a tennis player. CASE PRESENTATION An 18-y...

The term carpal instability is commonly used, but what carpal stability actually is has not been defined. Much of the mechanically complex wrist’s versatility is due to the intercalated three bone proximal carpal row. Landsmeer described the collapse tendency associated with intercalated segments. The factors which provide static stability are the oblique alignment of the scaphoid, the obliquel...

Scaphoid fractures are the most common fractures of the carpal bones, corresponding to 60%. Of these, 10% progress to nonunion; moreover, 3% can present necrosis of the proximal pole. There are various methods of treatment using vascularized and non-vascularized bone grafts. To evaluate and compare the rate of scaphoid consolidation with necrosis of the proximal pole using different surgical te...

This paper presents a review of the literature on pseudarthrosis of the scaphoid in skeletally immature individuals, taking into consideration its epidemiology, diagnosis and treatment, as well as its controversies. Knowledge of this subject makes it possible for patients to be given appropriate treatment immediately. Pseudarthrosis of the scaphoid in skeletally immature patients is a rare cond...

BACKGROUND Scaphoid malunion alters the carpal kinematics and impairs clinical outcome because of pain, weakness, restricted range of motion and predisposing the wrist joint to early osteoarthritis. The aim of this study was to evaluate the influence of the scaphoid morphological angles on clinical outcomes in patients with reconstructed scaphoid by non-vascularized bone graft. METHODS Sevent...

BACKGROUND There is no consensus on the optimum imaging method to use to confirm the diagnosis of true scaphoid fractures among patients with suspected scaphoid fractures. This study tested the null hypothesis that computed tomography (CT) and magnetic resonance imaging (MRI) have the same diagnostic performance characteristics for the diagnosis of scaphoid fractures. METHODS Thirty-four cons...
