cubitus valgus osteotomy

Elbow varus above 1.10° and elbow valgus above 20°, forming a severely deformed adult or child with dysfunction. 2. Elbow valgus with ulnar nerve dysfunction. Treatment of diseases: elbow valgus deformity elbow valgus Indication Elbow varus above 1.10° and elbow valgus above 20°, forming a severely deformed adult or child with dysfunction. 2. Elbow valgus with ulnar nerve dysfunction. Preoperative preparation Draw a horizontal line HO perpendicular to the humeral shaft at 1.5 to 2 cm on the humeral socket, and draw a slash GO at the O point to the iliac crest, so that HOG is equal to DEF, and the wedge GHO is designed to correct the elbow varus. The bone to be removed has a bottom edge on the temporal side. If the elbow is everted, the measurement method is inversion with the elbow, but the bottom edge of the wedge-shaped bone to be cut is on the ulnar side, and the angle of the osteotomy should be the angle of the valgus minus the carrying angle of 10°. Surgical procedure 1. Incision: A longitudinal incision of about 6 cm in length is made along the inside of the tibia and placed in the lower third of the upper arm. 2. Exposure: After incision of the deep fascia, a section of the ulnar nerve is freed in the ulnar nerve groove and retracted with a rubber strip to avoid damage. Separate the biceps and triceps gaps, retract the biceps and diaphragm muscles, retract the triceps, and cut the periosteum along the medial epicondyle to expose the upper part of the humerus. Front, back, and outer sides.
