Distal radius palmar bone fracture plate

Abstract

The invention discloses a distal radius palmar bone fracture plate. The distal radius palmar bone fracture plate comprises a bone fracture plate body, wherein the bone fracture plate body comprises a distal end section close to a wrist joint and a proximal end section, wherein and the top surface of the distal end section close to the wrist joint is of an inclined surface structure; a distal end upper kirschner wire hole, a distal end upper locking hole, a concave hole and a distal end lower locking hole are sequentially formed in the position, close to the wrist joint, of the distal end from top to bottom; the whole concave hole is in a shield shape; a sawtooth structure is arranged on the upper edge of the concave hole; a distal end lower kirschner wire hole is formed under the distal end upper locking hole; the distal end lower locking hole is positioned in the middle, close to the lower end of the wrist joint section, of the distal end; the proximal end section is sequentially provided with a sliding hole, proximal end locking holes and near-end lower kirschner wire holes from top to bottom; and proximal end upper kirschner wire holes are formed between the adjacent proximal end locking holes. The anatomical design of the bone fracture plate conforms to the anatomical characteristics of the distal radius, the bone fracture plate can be used as a reduction template for comminuted fracture, and excessive soft tissue stripping and blood supply stimulation damage are avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a volar bone plate at the distal end of the radius. Background technique [0002] The treatment of distal radius fractures mainly adopts external fixator and bone plate fixation. External fixators are mainly used for the treatment of obviously comminuted, open fractures, or distal radius fractures with severe soft tissue defects, but there are risks of needle tract infection, loss of reduction, and sensory damage to the radial nerve. Complex regional pain syndrome type I may also be present, especially if the external fixator is used for long-term, vigorous traction. Although open reduction and bone plate internal fixation can avoid the above problems to a certain extent, improper selection of bone plate and poor fracture reduction during operation will still lead to high complications, such as malunion (shortening of radius height), osteoarticular Inflammation, wrist d...

AI Technical Summary

Problems solved by technology

[0004] At present, bone plate treatment mainly faces the following problems: 1. The height of the radius is not restored enough, and it is more likely to be lost due to insufficient bone grafting or osteoporosis; 2. Because the proximal end of the radius is thinner than the distal end of the radius, the distal end of the radius should be fixed first and then the bone plate should be fixed. The proximal end tends to tilt up and deviate from the radius, and the proximal end cannot be fixed with screws; 3. Existing AO and biogenic bone plates are designed according to the anatomical characteristics of the distal end of the radius, and are used for anatomical locking and compression plate, but rarely for anatomical locking Compression plate as reduction template in treatment of distal radius fractures
