The degradation process of absorbable bone plates: Absorbable bone plates are mainly made of biodegradable materials, and their degradation process is closely related to the type of material. Take polylactic acid (PLA) as an example. This material degrades through hydrolysis in a water medium, causing the ester bonds to break, thereby generating oligomers or monomers, …

Characteristics of stainless steel bone plates: Material composition and properties: The main component of stainless steel bone plates is 316L stainless steel (alloys of iron, chromium, nickel, molybdenum, etc.), which has a relatively high density and weight, as well as high tensile strength and hardness. However, its elastic modulus is significantly higher than that of …

Advantages of titanium alloy bone plates Excellent biocompatibility: Titanium alloys can blend well with human tissues, and a stable oxide film can form on their surface. There are almost no toxic or side effects between them and human tissues, and they are less likely to cause rejection reactions in the body, rarely leading to allergic …

The changes in biomechanical properties after bone plate fixation are influenced by multiple factors. The following introduces the changes from different aspects: Early stage: In the early stage after bone plate fixation, since the fracture ends have not yet fully healed, the mechanical properties of the bone plate play a key role in maintaining the …

The process of bone remodeling after bone plate fixation Bone remodeling after bone plate fixation is an important stage in the later stage of fracture healing, involving the modification of callus and the recovery of bone structure. In the early stage of fracture healing, the primary callus forms, among which the new trabeculae gradually thicken …

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 …

The reasons for delayed healing after bone plate fixation can be summarized as the following multiple factors: 1. Local factors Insufficient stability of the fracture end: If there is slight movement at the fracture end after bone plate fixation, it will disrupt the formation of new callus, resulting in delayed healing. For example, loose bone …

The treatment methods for nonunion after bone plate fixation mainly include the following: Conservative treatment Drug therapy: Drugs that promote bone growth, such as bone peptide injection, can be used, which can regulate bone metabolism and induce the formation of new bone. At the same time, calcium supplements and vitamin D are taken to provide …
