Description
Technical Field
The utility model relates to a temporary fixator for the outer side wall of intertrochanteric fracture, and belongs to the technical field of medical auxiliary equipment.
Background
With the advancement of China into the aging society, the incidence of intertrochanteric fracture of femur rises year by year, and the age of the incidence also tends to rise. For unstable intertrochanteric fracture, internal fixing materials such as intramedullary nails are adopted to fix the fracture through operation, and early functional exercise is added, so that complications caused by long-term lying can be reduced to the greatest extent, and the life quality of patients is improved.
The stability of the post-operative fracture is determined by various factors such as bone quality (osteoporosis degree), fracture morphology (shattering degree), reduction quality (Garden alignment index), internal fixation selection, and placement position of the internal fixation. The quality of reduction of the fracture is one of the most important determinants and is largely influenced by the clinician's practice.
Partial complex intertrochanteric femoral fractures, such as fractures involving the greater and lesser trochanters, fractures in the total trochanter region, and fractures under the trochanter, can form a larger lateral wall fracture block that is often difficult to reposition and fix during intramedullary nail surgery. Even if anatomy reduction is realized under preoperative fluoroscopy, a series of operations such as reaming marrow and inserting thick main nail in marrow in the operation easily cause the displacement reduction loss of bone blocks, resulting in non-union of postoperative fracture of long-term patient
In order to prevent the displacement of the lateral wall fracture block in the operation, two methods can be generally adopted. Firstly, the outer side wall is reset and then fixed by a reconstruction steel plate, and the device has the advantages of good fixing effect, large wound, more soft tissue stripping, high cost and increased economic expenditure of patients; secondly, the soft tissue is bound and fixed by linear materials such as steel wires, titanium cables and the like, and the defects of serious soft tissue injury, troublesome operation and the like exist.
Therefore, the temporary fixator for the outer side wall of the intertrochanteric fracture is designed for temporary fixation, so that the displacement of a fracture block in the process of surgical operations such as reaming, nail placement and the like is avoided, the positive clinical significance is achieved, and the economic burden and the surgical trauma of a patient can be reduced.
