Fractures of the hand
Published in Peter Houpt, Hand Injuries in the Emergency Department, 2023
If there is a strong clinical suspicion of a scaphoid fracture, but there is no clear fracture visible on the initial X-ray, then the wrist should be immobilized and physical examination and X-rays repeated after two weeks. A CT scan can be a superior option.

History and clinical examination will lead the surgeon to suspect a scaphoid fracture or non-union, but confirmation of the diagnosis will come from imaging. Scaphoid series X-rays are an essential starting point. However, CT and MRI can provide additional information. The surgical plan will be affected by several key factors.
Orthopaedic Emergencies

The scaphoid has a critical role in the proximal carpal row and is important in maintaining radiocarpal stability. Orthopaedic review is essential to reduce complications and potential loss of function, as well as to exclude a missed injury such as: scapholunate dissociation with >4 mm space between these bones, radial styloid fracture, or even a Bennett's fracture of the base of the thumb metacarpal.Delayed complications of scaphoid fracture include avascular necrosis, non-union and osteoarthritis, which result in pain and loss of wrist function.
Successful closed reduction of a trans-scaphoid perilunate dislocation in a 11-year-old boy: a case report

An eleven-year-old, right-handed boy was admitted to the emergency department after falling from his bike on his extended right wrist. On examination, the wrist was painful, swollen and deformed. There were no neurovascular or cutaneous complications. Radiography revealed (Figure 1): a dorsal trans-scaphoid-perilunate dislocation of the right carpus, a styloid fracture of the radius, an avulsion fracture of the proximal pole of the triquetrum and an avulsion-fracture of the ulnar styloid. There is no classification for this type of lesion in children. Using adult classifications, the perilunate dislocation was a stage IIA lesion with dorsal displacement, according to the Herzberg classification [4], and a type II lesion according to the Witvoet and Allieu classification [11]. The scaphoid fracture was a waist pole fracture, according to the classification of scaphoid fractures used in children [1].
Scaphoid fracture geometrics: an assessment of location and orientation
Published in Journal of Plastic Surgery and Hand Surgery, 2019
In conclusion, this study provides a comprehensive assessment of the location and angle of scaphoid fractures in a large number of confirmed scaphoid fractures. It describes a statistical link between location and angle of the fracture thus possibly linking stability of scaphoid fractures with their location. It also is unique in its analysis of age and sex on fracture geometrics. The study confirms a link between scaphoid fracture location and non-union. The use of 3 dimensional simulations in scaphoid fracture surgery has been linked to higher quality surgery [29]. The authors believe that further studies employing 3 dimensional modelling techniques will contribute to predicting scaphoid fracture management, complications and sequelae.
A case of total scaphoid titanium custom-made 3D-printed prostheses with one-year follow-up
Published in Case Reports in Plastic Surgery and Hand Surgery, 2020
Sequelae of scaphoid fracture treatment include nonunion and necrosis of bone fragments. Carpal biomechanical changes can lead to scaphoid nonunion advanced collapse (SNAC) arthritis and severe degenerative osteoarthritis of radiocarpal and intercarpal joints. Surgical treatment options for the reconstruction of the scaphoid bone or, when that is impossible, for the prevention or treatment of late sequelae, include bone grafts (free or pedicled when the nonunion is isolated without collapse phenomena) [1–7], proximal row carpectomy [7,8], total or partial scaphoid removal in association with midcarpal arthrodesis, total wrist replacement, and total wrist arthrodesis [9]. However, no one method is considered to be the gold standard.
