Scaphoid fractures account for 70-80% of all carpal bone fractures 1. Although they occur essentially at any age, adolescents and young adults are most commonly affected 1. Older patients falling in a similar manner are more likely to sustain a distal radial fracture (usually a Colles fracture).
Patients will typically present with pain around the dorsal wrist and/or the anatomical snuffbox after a fall on an outstretched hand. The dorsum of the wrist may be edematous. Circumduction of the wrist is often painful 20. Pain may be elicited by palpation at the scaphoid tubercle (volar/radial), in the anatomic snuffbox, and just distal to Liste...
The usual mechanism is falling on an outstretched hand, applying an axial load to an extended and pronated wrist in ulnar deviation 7. Occasionally stress fractures are also encountered although these are less common, and only usually seen in athletes (e.g. shot putters or gymnasts) 8. Fractures can occur essentially anywhere along the scaphoid, bu...
A dedicated plain radiographic series investigating the scaphoid exists, consisting of four projections of the scaphoid bone. It is positionally different from the wrist series. It should, however, be noted that the initial radiograph can miss from 5-20% of fractures in the acute setting 1. Features include: 1. visualization of the fracture +/- dis...
In addition to stating that a fracture is present, a number of features should be sought and commented upon: 1. fracture 1.1. location (distal pole, waist, proximal pole) 1.2. involvement of articular surfaces 1.3. displacement or step 1.4. humpback deformitydue to angulation between proximal and distal parts 2. alignment 2.1. scapholunate interval...
Management options can broadly be divided into non-operative or operative management. 1. immobilization with thumb spica (or short arm) cast application 22,23 2. indications: 2.1. undisplaced fracture 2.2. normal radiograph but a high index of suspicion 3. outcomes: 3.1. fractures with <1 mm of displacement have a 90% union rate Union rates for non...
The term scaphoid derives from the Greek word σκάφος for boat. The bone profile is thought to look like a boat or skiff.
Learn about the epidemiology, clinical presentation, pathology, classification, radiographic features, and treatment of scaphoid fractures, a common carpal bone injury. Find out how to diagnose, stage, and monitor scaphoid fractures with various imaging modalities.
Learn about the causes, symptoms, diagnosis, and treatment of a scaphoid fracture, a break in one of the small bones of the wrist. Find out how the location and severity of the fracture affect the healing process and the risk of complications.
O escafoide é o osso do carpo mais comumente lesado. Fraturas do escafoide usualmente resultam da hiperextensão do punho, geralmente durante uma queda sobre a mão estendida. Podem interromper o suprimento de sangue à porção proximal do escafoide.
A scaphoid fracture is a type of wrist fracture that occurs most commonly from a fall on the outstretched hand. Learn about the causes, signs, diagnosis and treatment options for this injury, including surgery and non-surgical methods.
4 de ago. de 2023 · Objectives: Identify the common mechanisms of injury that lead to scaphoid fractures. Summarize appropriate evaluation and examination procedures, including diagnostic imaging, for a suspected scaphoid fracture. Describe the appropriate management options for scaphoid fractures.
Fratura de Escafoide. As fraturas de escafóide correspondem a até 90% das fraturas dos ossos do carpo, sendo causa frequente de atendimento nas unidades de ponto-atendimento. O mecanismo de trauma mais comum é a queda sobre a mão espalmada, mas pode ocorrer em decorrência a trauma direto. - ASSISTENCIAL. DIAGNÓSTICO.
