types of finger fracture
Distal Phalangeal Fractures The distal phalanx is the most commonly fractured bone of the finger.Distal phalangeal fractures are classified into three types: tuft fractures,shaft fractures, and intraarticular fractures. Tuft Fractures Atuft fracture involves the most distal portion of the bone.
Dislocations are described as dorsal, volar, or lateral depending on the direction of the middle phalanx to the proximal phalanx. A dorsal PIP dislocation is the most common type of finger dislocation. It usually involves injury to the volar plate and may include a volar plate avulsion fracture. A dorsal PIP dislocation often leads to obvious dorsal deformity of the middle phalanx and volar plate tenderness.
