Sivasha Compression-Distraction Apparatus

The Sivasha compression-distraction device is a medical device designed to gradually lengthen the bones of the limbs and correct their deformities. It was developed at the end of the 20th century by the Soviet surgeon G.A. Sivash is still widely used in traumatology and orthopedics.

The principle of operation of the device is based on gradual stretching of the bone by alternating periods of compression and distraction (stretching) using special screws and rods fixed in the bone. Compression promotes compaction of the bone at the site of fracture or osteotomy, and distraction stimulates new bone formation and bone lengthening.

The Sivash apparatus allows for both transosseous and intraosseous osteosynthesis. It has high reliability of fixation of fragments and provides precise control of the speed and magnitude of distraction. This makes possible the most safe and physiological lengthening of bones in patients with various pathologies.

Currently, the Sivash compression-distraction device is widely used for lengthening limbs in congenital and acquired deformities, treating false joints, and replacing bone defects. It can significantly improve the quality of life of patients and restore the anatomy and function of the limbs.
