What is the contribution of the Hohmann retractor

Hohmann retractors are an important tool used in orthopedic surgeries and are also referred to as bony lever retractors. This surgical instrument is primarily used in minimal or invasive knee and hip surgery. They are also used ideally for exposing the bony structures/segments and retracting the soft tissues away during arthroplasty.

This retractor comes in a wide range of lengths and sizes that are used for various applications. They generally feature curved profiles with flat and broad blades for ease of exposure and insertion. This tool is one of the most essential ones for orthopedic needs and is typically stocked up in a wide range in the orthopedic department.

Design

The structure of the Hohmann retractor is designed in such a way that the solid handle creates a blade by flaring out before narrowing again. Different designs have different degrees of curvature that depends on the intended use. Some of the designs are curved at 90 while others have shallow curves. In some surgeries, when there is difficulty to get appropriate leverage with a straight handle, this tool comes into use. It provides more traction for the practitioner.

History

Hohmann retractor is named after Georg Hohmann (1880-1970) who was a German orthopedic surgeon. He was the leader and instrumental member of the Gmeran orthopedic society. He had a considerable impact during his politically charged period in the field of orthopedics.

Georg Hohmann invented the Hohmann retractor with his fellow Dr. Lange with whom he had an assistantship at that time. Dr. Lange was known for being the pioneer in the field of orthopedics by bringing it out from under the shadows of general surgery.

Final words

 Hohmann retractors hold vital importance in the field of orthopedics. This tool is used by medical practitioners manually and is not padded so it can be cleaned easily. There are also holders available for these retractors that lock the end of this tool and keep them in place.
