Application of medical titanium nail in plastic surgery

Titanium is non-toxic and non-magnetic. The elastic modulus of titanium alloy is similar to that of human bones. It has good compatibility with human body and is therefore called "biometal". Titanium is also an important member of the memory alloy family. Nickel-titanium alloy is the first alloy that people have found to have memory defects. This alloy can "remember" its own sky. After it is deformed by external force, it only needs to give the corresponding temperature. Can "re-emerge" and restore the original shape. And because it contains titanium, its strength is also very high. Therefore, this alloy has become the most versatile memory alloy, and today it is still one of the best performing shape memory alloys. The use of titanium and titanium screws to treat fractures has unexpected effects. As long as months, new bones and muscles will combine with titanium. Therefore, titanium is an ideal human dental implant and artificial joint material.

The humerus plastic surgery mainly includes two concepts: one is simple humeral chiseling to reduce the outer contour of the humerus; the other is three-dimensional osteotomy, which achieves the reduction of the tibia through the shortening and movement of the bone. Tibial chiseling, generally suitable for patients with anterior and lateral facial protrusions, often using intraoral incision, separation of the humerus under the periosteum, special equipment to cut the humerus part of the preoperative design to be thinned, thereby reducing The outer contour of the face improves the face. The use of titanium nails and titanium plates is fixed for the purpose of not causing slippage of the tibia, resulting in facial contour loss, and better effect of shaping the tibia!

The biggest advantage of this type of surgery is that no scars are left after surgery, and the clothes are seamless and leave no traces. The difficulty in the operation of the three-dimensional osteotomy of the humerus is greatly increased, and it is suitable for patients with prominent zygomatic arch. In addition to the intraoral incision, it is usually necessary to make an auxiliary incision in the concealed part of the hairline, or a single incision in the scalp. After the subperiosteal separation exposes the entire humerus, the specific size of the bone is removed according to the needs of the computer three-dimensional simulation design. Re-attach and shape the separated bones with special materials such as titanium nails, which can maximize the contour and shape of the entire face, and even allow the patient to achieve the effect of “reborn”. In addition to the reduction of the humerus, for a small number of patients due to congenital or acquired diseases such as sacral dysplasia or defects caused by local dysplasia, or bilateral axillary asymmetry, can be transplanted through autologous tissue or fake The body material is filled with ankle humerus for treatment to achieve the purpose of improving the appearance.
