Background technique
Orthopaedics is one of most common department of various big hospital, main dissection, physiology and the pathology for studying skeletal musculature,
The normal morphology and function of this system are kept and developed with drug, operation and physical method.With the change in epoch and society
More, injury of orthopaedics department spectrum has apparent variation, for example, the diseases such as tuberculous osteoarthropathy, osteomyelitis, infantile paralysis significantly reduce,
Wound caused by traffic accident increased significantly.The variation of injury of orthopaedics department spectrum, this just needs orthopaedics to grow with each passing hour.Spine fracture is
The common wound of orthopaedics.Its incidence accounts for the 5%~6% of fracture, is secondly neck, lumbar vertebrae, chest with thoracolumbar fracture incidence highest
Vertebra is minimum.Clinical manifestation is deformity, the pain of wound posterior spinal, often can concurrent spinal cord injury.To spine fracture or misplace into
Fixed plate is used in capable some operations, fixed plate is anchored on the bone tissue of backbone using the bone fastener across fixed plate
On, combine two or more vertebral bodies so that a part of backbone is fixed at the desired position.Fixed plate needs to meet
In long-term use with the reliability of the stability of backbone and system, guarantee that bone fastener will not be unclamped or be exited from plate,
Ensure the fixation between plate and bone.
A kind of spinal fixation system disclosed in Chinese utility model patent ublic specification of application CN104856748B,
The spinal fixation system, although bone plate may be alternatively provided as that upper layer nail hole is coaxial with lower layer nail hole, and lower layer's nail hole is relative to upper
Layer nail hole has indented section, or is set as slope of the slope greater than upper layer nail hole side wall of lower layer's nail hole side wall；So set,
Screw is screwed in into upper layer nail hole, when being screwed onto lower layer, the diminution of lower layer's nail hole internal diameter has certain effect of keeping out, but this layer of bullet to screw
Property modulus is small, therefore screw can be screwed into lower layer hole outwardly against the layer, be fixed on bone, and lower plywood has extruding in the side of screw
Effect.Meanwhile having clamping block in the fixation hole by the nail hole of upper layer, rotation locking block can resist ailhead in the part on bone plate upper layer.
Therefore, the ailhead of screw is fixed block in bone plate upper layer and resists, and the extruding force from bone plate, spiral shell are received in bone plate lower layer
Nail will not be exited from plate, and still, which has the shortcomings that bone plate is excessively rigid, when patient's carry out activity,
It will lead to backbone to be damaged.
