Introduction to phalanx fractures

Fractures of the phalanges are the most common in the hands, and most of them are open fractures. And most of them are caused by direct violence, which can cause various types of fractures on any part of the finger. Due to the different parts of the phalanx fracture, it is pulled by tendons from different directions, resulting in displacement in different directions. For example, the fracture of the proximal phalanx is caused by the traction of the interosseous and lumbric muscles, resulting in an angle to the palm. ; The middle phalanx fractures at the distal end of the superficial digital flexor tendon, and it also produces an angle to the volar side due to its traction; if it is fractured at the proximal end of the superficial digital flexor tendon, it will be pulled by the extensor tendon to cause an angle to the dorsal side (figure 1). Intra-articular fractures at the base of the proximal phalanx can be divided into three types: collateral ligament tear, compression fracture, and longitudinal split fracture. The distal phalanx fractures are mostly comminuted fractures, often without significant displacement; while the avulsion fractures on the dorsal side of the base of the distal phalanx usually form a mallet finger deformity.
