Hallux Valgus (bunions)
Bunions are usually caused by shoes that are too narrow . The basic characteristics are deviations of the large toe toward the small toe (lateral), “bone balls” on the inner side of the basic joint (macrophalangeal joint) of the large toe, extension of the front part of the foot (splayfoot), pain in the sole of the foot, twisting of the large toe, and additional deformations of the small toes.
If conservative methods of treatment such as shoe inserts do not work, an operation is necessary.
There are many types of operations:
This procedure is indicated if a deformity is responsible for the bunion. A wedge is removed from the proximal phalanx (near side of the toe bone), and the ends of the bone are reset. In this way the axis of the toe bone is corrected.
We use this method for mild or medium severe cases. Here we use a wire or a screw that can be removed after a few weeks under local anesthesia.
Basic wedge osteotomy
In severe forms of bunions, basic wedge osteotomy is a procedure that is used in stable joint relationships. In this procedure, a portion of the bone wedge on the first central foot bone is removed, resulting in a straightening of this bone.
Open wedge osteotomy
This new operation is used in a severe form of bunions. With today's new implants that have a stable angle screw joint, the patient can be weight-bearing quite soon. The first center foot bone is straightened by folding back the bone.
