Product Description
The Knee Joint External Fixator can be used for the correction of traumatic knee varus, valgus, bone angulation and shortening deformity.
Ilizarov ring external frame technique, also known as external osteosynthesis, treats trauma and deformity by External Fixation of the injured limb. After osteotomy for traumatic knee valgus deformity in adolescents, the knee lower limb external fixation can gradually correct the valgus deformity and avoid the nerve dysfunction caused by excessive angulation of the common peroneal nerve.
Parts
The main components were as follows: 4pcs rings, 2pcs half rings, 4pcs threaded column, 1pc annular diagonal tie, 2pcs posts with 4 edges, 2pc single joints, 16 pin clamps and 12pcs M6 threaded rods
The orthopedic surgery procedures of knee joint external fixator system
1.Install the external fixator traction device: set on the affected limb, with the knee joint space as the center, requires that the middle part of the spring corresponds to the center of the internal and external knee joint space. The plane of the external fixation ring in the two groups should be perpendicular to the femoral shaft and tibial shaft, respectively, and the distance between the inner edge of the ring at the joint and the skin should be more than 4 cm.
2.The position of the knee joint space and the spring was determined by anteroposterior and lateral fluoroscopy: the position of the external fixation ring and the knee joint and the position of the piercing needle in the two groups were adjusted to avoid blood vessels and nerves. A 2.5 mm orthopedic Bone Screw was inserted into each ring, and then a 4.0 mm half bone screw was inserted into each ring at the corresponding position. At least one bone screw plus one half bone screw was placed on each ring, and the two bone screws were crossed by 60° to 80°. A total of 8pcs traction screws (4pcs whole screws and 4pcs half screws) were inserted into the 2 groups of 4 rings and fixed on the corresponding 2 groups of rings with ring clips. The traction position of the ring and the knee joint was confirmed by fluoroscopy again. Each whole screw was stretched and fixed, and a traction device was installed between the two groups of rings.
3.Patellar traction and screw insertion: according to the degree of patellar adhesion, the patella was fixed with 2pcs half screws or a half screw and a screw, the patella was stereostereotically fixed with half rings and connectors, and the patellar traction device was connected to a group of rings at the distal end with 2pcs screw rods.
4.Fluoroscopy confirmed that the direction of knee flexion and extension was appropriate: after adjusting the spring-hinged Ilizarov external fixator, the direction and position of the affected knee reached the maximum flexion Angle were confirmed by fluoroscopy, and the distraction device was returned to the initial state.
5.Note,cut off the needle and the excess part of the end, and give bending, wear protective cap at the end of the screw; The screw was covered with sterile excipients, and the holes of the screw were wrapped with 1 or 2 pieces of sterile excipients, and properly fixed with medical tape.
The application of knee joint large fragment external fixation (spring-hinged Ilizarov external fixator) can imitate the normal knee joint motion trajectory, effectively rehabilitate the knee flexion and extension function, and reduce the incidence of knee joint dislocation, ligament rupture and other complications.
