The causes of bone plate fracture
Surgical technical issues:
The screw holes of the bone plate are located on the fracture line, and the stress is prone to concentrate in the screw holes, resulting in the fracture of the bone plate.
When the cortical defect on the opposite side of the bone plate is greater than 2mm, stress is concentrated on the bone plate, which can cause fracture.
The bone plate is too short or the number of screws is insufficient, resulting in weakened fixation and uneven stress distribution.
The position of the bone plate was improperly placed and the principle of fixing the tension side was not followed, causing the bone plate to bear excessive tensile stress.
Steel plate quality issues:
The steel plate itself has quality problems or defects, such as minor secondary damage or bubbles during the processing, which leads to stress concentration and causes fatigue fracture of the inner plant.
Poor fracture healing
During the process of fracture healing, delayed healing or non-healing occurs, resulting in continuous stress on the steel plate and causing fatigue fracture.
Premature weight-bearing or inappropriate functional exercise:
Premature weight-bearing or inappropriate functional exercises before the fracture heeded subjected the steel plate to excessive stress, leading to fracture.
Osteoporosis
Osteoporosis caused by the elderly or long-term use of hormones and other reasons makes fracture healing difficult and plates prone to fracture.
Prevention of bone plate fracture
Select the appropriate bone plates and screws:
Select the appropriate length and width of the bone plate based on the type and location of the fracture, and ensure that there are sufficient screws for firm fixation.
Avoid using bone plates with screw holes located along the fracture line. Try to choose bone plates with an even number of holes or those without a hole area in the center.
Ensure the accuracy of surgical techniques:
During the operation, it is necessary to ensure that the bone plate is accurately installed and the screws are firmly fixed to avoid infection at the surgical site.
Try to perform anatomical reduction as much as possible to minimize cortical bone defects. If the defect is too large, bone grafting is required.
Follow the principles of rehabilitation exercises:
Patients should strictly follow the doctor’s advice for rehabilitation exercises and avoid premature weight-bearing or inappropriate functional exercises.
Functional exercises should be carried out under the guidance of a doctor, with the principle of no stress in the affected bone, and the activity level should be gradually increased.
Strengthen the prevention and treatment of osteoporosis:
For patients with osteoporosis, active anti-osteoporosis treatment should be carried out to enhance bone strength.
Supplement sufficient calcium and vitamin D to promote an increase in bone density.
Regular follow-up and examination:
Regularly visit the hospital for follow-up and examination to promptly identify and address issues such as poor fracture healing.
If any abnormal conditions such as loose bone plates or pain occur, medical attention should be sought promptly.
