The correction methods for angulation deformity after bone plate fixation mainly include the following:
Manual reduction and fixation:
For fractures and deformities within two weeks that affect functional recovery and fracture healing, manual reduction and fixation can be chosen again. When performing manual reduction, the operator can correct angular deformity by using specific techniques, such as pushing the distal end with the thumb and pressing the other four fingers to form an angular protrusion. If manual reduction is unsuccessful, surgical reduction can be considered, and internal fixation devices such as steel plates and screws can be used for fixation.
The fixation methods include using plaster casts, braces, etc. to provide stable support and protection for the affected area, limit the range of motion, and prevent further displacement. Fixation helps promote the natural healing process and reduces pain and discomfort caused by movement.
Orthopedic surgery
Orthopedic surgery usually involves making an open incision to enter the affected area and using internal fixation devices such as metal plates and screws to adjust the position of the bone and keep it upright. This measure is aimed at angulation deformities, with the goal of correcting incorrect skeletal arrangements, restoring normal anatomical structures, and alleviating functional disorders caused by asymmetry.
For cases of excessive angulation deformity or failure of manual reduction, osteotomy may be required for correction. Osteotomy can correct the combined angle-translation deformity by rotating the angle-forming center of osteotomy and restore the alignment of the bone mechanics axis.
External fixator technology
External fixator techniques such as the Ilizarov technique can be used for the correction, reduction and stable fixation of any type of deformity. It can be achieved through minimally invasive percutaneous fixation techniques, with a very small degree of soft tissue dissection and promoting the growth of bone tissue at the same time.
When using an external fixator, doctors can adjust the external fixator frame as needed to modify and enhance the treatment. For example, rotational deformity is corrected by gradually twisting the newly formed bone between the two fracture segments, or residual displacement is corrected by simple operations using the moving axis of the external fixator.
Functional exercise and rehabilitation
A series of progressive rehabilitation exercise programs are carried out under the guidance of professionals, aiming to restore the strength and flexibility of the injured limb. Exercise can enhance muscle strength, improve blood circulation and nerve function, but it is necessary to be careful to avoid overuse that may cause secondary injuries.
Regularly recheck X-ray films to monitor the healing of fractures and the effect of correction, and adjust the rehabilitation plan according to the recovery situation.
