External fixing rack for hip fracture

Abstract

The invention provides an external fixing rack for hip fracture, and relates to an instrument for orthopedic external fixation treatment. The external fixing rack for hip fracture is provided with two fixing handles penetratingly fixed with bone screws; at least two universal joints are arranged at the head of the upper fixing handle, the angle between each universal joint and the head of the upper fixing handle can be changed, and each universal joint is penetratingly fixed with one bone screw; at least one universal joint is arranged on the lower portion of the lower fixing handle, the angle between each universal joint and the head of the upper fixing handle can be changed, and each universal joint is penetratingly fixed with one bone screw; and the upper portion of the lower fixing handle is slidably sleeved in a guide groove on the lower portion of the upper fixing handle and is fixed in the guide groove by a jackscrew arranged on the lower portion of the upper fixing handle. The external fixing rack can be used for external fracture reduction repeatedly, has a good and sufficient sliding prizing effect, can effectively maintain the proximal end of the fractured hip of a patient at an external unfolded position, is flexible and various in adjustment mode, and is applicable to complex fracture conditions.

Description

technical field [0001] The invention relates to an instrument for orthopedic external fixation surgery. Background technique [0002] Surgical treatment of hip fractures is currently mainly based on internal fixation. For elderly patients with hip fractures and osteoporosis, the bone has insufficient holding force on the bone screws, coxa varus, shortening of the affected limb, medial displacement of the distal segment of the fracture, and cutting of the lag screws after internal fixation The incidence of complications such as cortical bone screw pullout is greatly increased, which can easily lead to the failure of internal fixation. For patients with hip fractures that are difficult to treat with internal fixation, the use of hip external fixators has certain advantages. In clinical application, the traditional hip fracture external fixator has the following disadvantages: 1. It is bulky; 2. It lacks sufficient sliding and prying effect, which often leads to the occurrenc...

AI Technical Summary

Problems solved by technology

In clinical application, the traditional hip fracture external fixator has the following shortcomings: 1. It is bulky; 2. It lacks sufficient sliding and prying effect, which often leads to the occurrence of coxa varus; 3. The trauma is often large and the operation is complicated.

However, it also has the disadvantages of insufficient sliding and prying range for the proximal end of the fracture, insufficient fixation, single adjustment method, and inability to adapt to complex fracture situations.
