The correction strategies for rotational deformity after bone plate fixation mainly include the following types:
Manual reduction and fixation:
For fractures with rotational deformities within two weeks that affect functional recovery and fracture healing, manual reduction can be attempted. During manual reduction, the doctor needs to rotate the fracture end to the normal position through specific techniques based on the deformity condition, and use fixation materials such as plaster and braces for fixation to maintain the stability of the fracture end.
If manual reduction is unsuccessful, or if the fracture has lasted for a long time and the deformity is severe, surgical reduction should be considered. During surgical reduction, the doctor will make an incision at the fracture site, directly observe and adjust the position of the fracture ends, and then use internal fixation materials such as plates and screws for fixation.
Orthotic appliance or external fixator technology
For mild rotational deformities, orthotics or external fixators can be used to fix the limb position and prevent further rotational deformities. Orthotics or external fixators can continuously apply external force to the fracture end to guide its growth in the normal direction.
The Ilizarov technique is a commonly used external fixator technique. It can continuously and stably traction and correct the fracture end by gradually adjusting the tension of the external fixator, and is suitable for various complex rotational deformities.
Osteotomy
For severe rotational deformities, especially when accompanied by other deformities such as angulation and shortening, osteotomy may be required. Osteotomy can re-cut the bone, adjust its position and Angle, and then fix it with internal fixation materials.
When performing osteotomy, doctors need to select the appropriate osteotomy plane and Angle based on the specific conditions of the deformity to ensure the corrective effect.
Rehabilitation training and physical therapy
In the process of correcting rotational deformities, rehabilitation training and physical therapy also play important roles. Rehabilitation training can enhance muscle strength, improve joint range of motion, promote fracture healing and the recovery of limb function.
Physical therapies such as hot compress, massage and acupuncture can promote local blood circulation, relieve pain and muscle tension, and create favorable conditions for fracture healing.
