Problems solved by technology

However, when the fracture line involves the articular surface and is crushed, there is a problem that cables cannot be used for fixation, which greatly increases the difficulty of treatment.
[0003] The current treatment method adopts the combination of locking bone plate and screw fixation. Due to the unique direction of the screw path, it is impossible to match a reasonable plan according to the patient's fracture condition.
There are mainly the following problems. First, after the anatomical reduction of the small bone fragments, it is impossible to choose the appropriate direction for fixation, and it is impossible to pressurize them.
Second, too many locking screws are implanted, causing bone loss, and the patient's foreign body sensation is enhanced, which will bring more pain to the patient and the operation is complicated, which increases the operation time
Third, using Kirschner wires with cables alone can only perform partial reduction, and the holding force of Kirschner wires with cables to bones cannot reach the required strength and cannot meet the situation of intra-articular fractures

Embodiment 1

[0054] A fracture fixation system, comprising a bone plate 1, a first locking member 2, a second locking member 3 and sutures 4, the bone plate 1 includes a bone plate head 5 and a bone plate head 6, the bone plate head 5 A plurality of first locking holes 7 are arranged on it, and the first locking member 2 is set in the first locking holes 7 and passes through the humeral shaft. A plurality of second locking holes 8 are arranged on the bone plate head 6, and the second locking The hole 8 is provided with a second locking member 3, and the suture thread 4 passes through the cavity inside the first locking member 2 to surround and fix the bone block.

[0055] The bone plate head 5 includes a first fixing plate 9 and a second fixing plate 10, there is a transition surface connection between the first fixing plate 9 and the second fixing plate 10, and the connection between the first fixing plate 9 and the second fixing plate 10 is L type.

[0056] Both the first fixing plate 9...

Abstract

The present invention provides a fracture fixing system. The fracture fixing system comprises a bone plate, a first locking piece and a suture line; the first locking piece is provided with a longitudinal axis and provided with a first end and an opposite second end along the longitudinal axis; the first locking piece is provided with a cavity extending from the first end to the second end; the first locking piece is arranged in a first locking hole in the bone plate and penetrates out of a bone; and the suture line penetrates through the cavity of the first locking piece to fix the bone block. Compared with a traditional fixing system comprising a bone plate with suture holes, the bone fracture fixing system has advantages that bone blocks are fixed more firmly, a fixing effect is better,the suture holes do not need to be formed in the bone plate, and strength of the bone plate is guaranteed, and is particularly suitable for fixing condyle fractures with small fracture blocks difficult to fix in comminuted fractures.

Description

technical field [0001] The invention relates to the field of medical instruments, more specifically to a fracture fixation system. Background technique [0002] In the clinical treatment of orthopedics, comminuted fractures, multi-fragment fractures, and complex fractures often occur. In the prior art, bone plates and locking screws are often used for treatment, or Kirschner wires and cables are used to fix the fractures. Small bone fragments are fixed for treatment. However, when the fracture line involves the articular surface and is crushed, there is a problem that cables cannot be used for fixation, which greatly increases the difficulty of treatment. [0003] The current treatment method adopts the combination of locking bone plate and screw fixation. Since the direction of the screw track is unique, it is impossible to match a reasonable plan according to the fracture condition of the patient. There are mainly the following problems. First, after the anatomical reduc...
