Description
Technical field
This utility model relates to technical field of medical instruments, relate in particular to a kind of femur distraction reduction device with and application in fracture of shaft of femur.
Background technology
Fracture of shaft of femur is common fracture, accounts for 5% of whole body fracture, and it is more common between twenty and fifty crowd, how because of fall down, due to the high falling etc.Because femoral shaft is the longest and the strongest bone of human body, its walking to human body, stand and labor capacity has and important function, effectively the fracture of shaft of femur treatment has significant meaning to the reduction disability rate.
Femur is long tubular structure, scope comprises that the tuberosity level is to condyle of femur from childhood, there are a plurality of powerful muscle groups to adhere to around it, be subjected to the effect of a plurality of muscle strengths after the fracture of shaft of femur and make thigh produce deformity, the iliopsoas tractive makes nearly fracture end flexing and outward turning when femur nearly 1/3 is fractured, adductor most fracture of shaft of femur are produced axially and in turn over stress, Methods for Distal Femoral Fractures becomes the angle because the traction action of gastrocnemius then makes fracture end trend towards flexing.So the key for the treatment of fracture of shaft of femur is that balance is dissected para-position and carried out early functional exercise.
Most clamping plate, traction and the Gypsum Fibrosum braces etc. of adopting of fracture of shaft of femur carried out expectant treatment in the past, since can't provide enough strength with keep fracture to line, and external fixation very easily causes consequences such as ankylosis, multiple bed complication for a long time, continuous development along with new internal fixation technology, as not having special contraindication, the operative treatment of fracture of shaft of femur has become the prefered method for the treatment of.And recover limbs to line, rotation and length, preserve blood supply promoting union of fracture and to protect from infection, the Therapeutic Principle who promotes to suffer from the rehabilitation of limb and whole body has obtained consistently to approve.
Open reduction steel plate inner fixation treatment of femoral shaft fractures has been applied to clinical decades as traditional operation method, it can be looked at straight down and carry out the reduction of the fracture and fixing, correct fracture cripetura and rotation deformity, pressurization and steel plate screw are fixing between sclerite can obtain very firm fixing, early ambulant can be allowed and excellent function can be obtained, and it needs heavy fracture traction bed or XRII unlike the closed plug pin of femur, operation technique is convenient.But need to cut fracture surrounding soft tissue in the steel plate fixation on a large scale, many even the need blood transfusion of operative hemorrhage, fracture end hematoma and sludged blood have been removed in the art, especially the periosteum that needs extensive cleavage fracture end and sclerite profit resets, the blood confession that has destroyed around the fracture and pulverized the bone piece, removed the somatomedin of favourable union of fracture in the original hematoma of fracturing, and it is that marrow is outer eccentric fixing, so scar after the operation hypertrophy, infect, bone delay in healing, postoperative complications such as bone does not connect and internal fixation failure even steel plate fracture still take place often, and the stress-shielding effect of steel plate after causing getting inner matter the femoral shaft refracture takes place easily.
At present, the steel plate fixing means is only applicable to the patient that key pulp cavity is narrow especially, fracture of shaft of femur merges the homonymy fracture of femoral neck, fracture line relates to metaphysis, merging arterial injury or unstability spinal injury.
