Herbert Screw

A Herbert screw is a type of orthopedic implant used in orthopedic surgery for fixation of fractures, particularly in the hand and foot. It is named after the orthopedic surgeon, Dr. Herbert, who first introduced this type of screw for surgical use.

History

The Herbert screw was developed as an improvement over traditional screw fixation methods due to its design that allows for compression across the fracture site. This compression helps in promoting faster healing and better stability of the fracture.

Design

The Herbert screw is a type of cannulated screw with a hollow core that allows for insertion over a guide wire. It has a threaded design that provides excellent grip in the bone, preventing loosening or migration of the screw post-surgery.

Surgical Technique

During surgery, the Herbert screw is inserted over a guide wire into the bone fragments on either side of the fracture. Once in place, the screw is tightened, compressing the fracture site and holding the bone fragments together for proper healing.

Indications

Herbert screws are commonly used in fractures of the scaphoid bone in the hand and the talus bone in the foot. These screws are particularly useful in fractures that require compression across the fracture line for optimal healing.

Complications

While Herbert screws are generally considered safe and effective, complications such as screw loosening, breakage, or migration can occur. In some cases, removal of the screw may be necessary if complications arise.
