The key points for choosing bone plates for limb fractures mainly include the following aspects:
Fracture type and location:
Different types of fractures require different types of bone plates. For example, long bone fractures may require specially designed long bone plates, while fractures of small bones (such as the wrist or hip joint) need corresponding small plates.
The location of the fracture also affects the selection of the bone plate, as certain positions may require specially designed bone plates to ensure stable fixation.
Bone size and shape:
The size and shape of the bone plate should match the bone at the fracture site. For larger or irregularly shaped bones, specially designed bone plates may be required.
The length of the bone plate should usually be no less than 4 to 5 times the diameter of the fixed backbone to ensure sufficient stability.
Mechanical properties of bone plates:
The bone plate needs to have sufficient strength and stability to withstand the weight and force of the fracture site.
Locked bone plates and non-locked bone plates each have their advantages. The locking bone plate provides a better fixation effect through the angular stability between the bone plate and the screw, especially suitable for patients with osteoporosis. Non-locking bone plates can have a greater Angle adjustment when screwed in.
Biocompatibility and materials
Medical bone plates usually use materials with good biocompatibility, such as titanium alloy or stainless steel, to reduce the rejection reaction of the human body to the implant.
In some cases, biodegradable materials may be used to reduce the need for secondary surgeries.
Surgical techniques and doctors’ experience:
The doctor’s skills and experience play an important role in the selection of bone plates. Some doctors may prefer to use a certain specific type of bone plate because they have more experience with the performance and usage methods of this bone plate.
During the operation, the placement position of the bone plate and the fixation method of the screws should be considered to ensure the best fixation effect.
Postoperative recovery and complications:
When choosing bone plates, their impact on postoperative recovery should be considered, including promoting bone healing and reducing complications (such as infection and rejection), etc.
The design of the bone plate should minimize the damage to the surrounding soft tissues and bone blood supply as much as possible.
