What type of injury classifies as a Holstein-Lewis fracture?

A Holstein-Lewis fracture specifically refers to a fracture of the distal humerus that is associated with the potential for nerve entrapment, particularly affecting the radial nerve. This injury often occurs in the context of a fall onto an outstretched hand or direct trauma to the elbow, leading to a fracture that may compromise surrounding structures, including nerves.

The significance of identifying a Holstein-Lewis fracture lies in its implications for treatment and prognosis. The entrapment of the radial nerve can lead to wrist drop and loss of extension at the elbow, necessitating careful monitoring and potential surgical intervention to relieve the nerve compression.

Other fractures around the arm and elbow, such as those of the proximal humerus, distal radius, or the elbow joint itself, do not fall under the specific classification of a Holstein-Lewis fracture because they do not typically involve the distal humerus in conjunction with radial nerve involvement. Understanding the distinctive characteristics of such fractures is essential for appropriate management and surgical considerations in orthopedic practice.
