Forearm Fractures and Instabilities-Overview-Forearm

Overview-Forearm

Pdf Summary

Chapter 13 of the document discusses fractures and dislocations in the forearm. The unique structure of the forearm allows for pronation and supination movements, which are important for hand function. Loss of this motion due to malunion or trauma can be disabling. Forearm fractures are often the result of high-energy injuries and can be complicated by compartment syndrome, neurovascular injury, bone loss, and post-traumatic synostosis. Infection is rare due to easy wound debridement and good blood supply in the forearm muscles. The chapter also provides details on the anatomy of the forearm, including the shape and structure of the ulna and radius, as well as the ligamentous structures that maintain the association between the bones. Operative exposures for the ulna and radius are described. The chapter explains the treatment options for forearm fractures, including plate fixation, intramedullary implantation, and nonoperative treatment. Open fractures can be treated with immediate plate fixation, which has a low rate of infection. The chapter also discusses specific fracture-dislocations in the forearm, such as the Galeazzi, Monteggia, and Essex-Lopresti lesions, and their treatment. The interosseous membrane (IOM) in the forearm is important for maintaining stability and supporting forearm function. Pathology in the IOM can occur in cases of longitudinal radioulnar dissociation, and the successful treatment relies on maintaining forearm length and stability. The chapter concludes with a list of suggested readings and figures for reference.
