Lauenstein fracture

A Lauenstein fracture is a fracture of the navicular bone of the foot. Named after the German surgeon Hermann Lauenstein, who first described this type of fracture in 1902.

A Lauenstein fracture usually occurs when someone falls from a height or hits the foot with a heavy object. In this case, displacement of fragments of the scaphoid bone occurs. Clinically manifested by pain and swelling in the area of ​​the talonavicular joint, limited mobility of the foot.

Diagnosis of a Lauenstein fracture is based on X-ray data of the foot in lateral and direct projections. Treatment consists of repositioning and fixing the fragments with knitting needles or screws, and, if necessary, bone grafting of the defects. Complications may include fracture nonunion and deforming arthrosis of the talonavicular joint.

With timely and adequate treatment, the prognosis for a Lauenstein fracture is generally favorable. Full restoration of foot function occurs within 2-3 months after the injury.
