Embodiment 1

[0080] Example 1: After successful anesthesia, clean the affected limb 3 times aseptically, rinse the wound surface and its surroundings with Type III Aner’s iodine solution, and normal saline, disinfect and spread the drape, expand the wound, explore, remove pollution, necrosis, and inactivated tissue, Scrape off the bone end and polluted tissue in the medullary cavity, retain free bone fragments, rinse the wound again with type III Aner's iodine and normal saline, reapply the drape, reset the free bone fragments, and choose the fixation method (plate, intramedullary nail or external fixator) The cancellous bone particles from the anterior or posterior superior iliac crest of the autologous bone were implanted into the medullary cavity or around the cortex of the fracture segment, and the free bone fragments were repeatedly rinsed and soaked with type III Aner's iodine for 3 to 5 minutes. The fascia and soft tissue around the bone graft area are covered with vacuum-sealed (VSD...

Abstract

The invention discloses a method for fixing open bone defect by negative-pressure closed irrigation and autograft. The method comprises the following steps of washing a wounded limb three times by using a sterile brush after anesthesia on a patient is successful; washing a wound surface and the periphery of the wound surface by using III-type entoiodine liquid and normal saline sequentially; sterilizing and paving a drape; performing debridement and probing; removing polluted, necrotic and deactivated tissues; striking off polluted tissues of capitula and medullary space; reserving free bone blocks; irrigating a wound again by using III-type entoiodine and normal saline; paving a drape again; resetting the free bone blocks; fixing the free bone blocks by selecting a steel plate, intramedullary nails or an external fixing rack; covering anadesma and soft tissues surrounding a bone planting area by using negative-pressure closed irrigation dressings; detaching a negative-pressure closed irrigation and perfusion device; probing the wound surface; selectively performing negative-pressure closed irrigation and skin flap transfer surgery or skin-grafting and negative-pressure closed irrigation surgery on the granulation wound surface again; and closing the wound surface. By using the method, infection, osteomyelitis, delayed union and bone ununion can be effectively prevented, the level of the clinical medical science is improved, and the therapeutic cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of clinical medicine and orthopedic treatment, and in particular relates to a method for fixing open bone defect by negative pressure airtight lavage and autologous bone grafting. Background technique [0002] Post-traumatic bone and soft tissue defects caused by high-energy trauma are often combined with multiple complex injuries. The disease is severe, the treatment cycle is long, and tissue reconstruction is complicated. Therefore, it is difficult to obtain a high-level, systematic and clear treatment plan. [0003] Due to the diversity of causes of open fractures of the extremities, especially wounds caused by high-energy injuries such as impact injuries, crush injuries, and blast injuries, the wound surface is seriously polluted, foreign bodies remain, and continuous tissue necrosis may occur. Improper handling of this visit resulted in loss of skin and soft tissue, loss of bone fragments, bone compress...
