Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The treatment is difficult even surgery because of lack of blood supply of lateral condyle,unstability from muscle force and the articular fluid inhibition of union.
The author try to improve the healing of the fracture after surgery by "4 not techniques",
1. the surgical approach should not enter posteriorly because the blood supply of lateral condyle enter posteriorly in order to avoid cut the vessels.
2. The dissection should not too much especially the muscle around the condyle.
3. It is not necessary to perfectly reduced the fracture after nonunion to avoid too much dissection the muscle and allow only healing of the fragment.
4. Bone graft is not necessary. The author wants to know the results after perform "4 not technique" in delayed union and nonunion of lateral humeral condyle fracture

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The children who received the previous surgery of the same elbow will be excluded.
After full explanation and discussion to the children and parents.The surgery in "4 not technique" will be performed.
1. the lateral approach of the affected elbow and enter the fracture anteriorly. The approach should not enter posteriorly because the blood supply of lateral condyle enter posteriorly in order to avoid cut the vessels.
2. The dissection should not too much especially the muscle around the condyle. The nonunon fragment will be cleaned,washed and made until the healthy bone surface of fracture appear in both side of fracture.
3. It is not necessary to perfectly reduced the fracture after nonunion to avoid too much dissection the muscle and allow only healing of the fragment.The fixation by K-wires or screw in older children until the fragment is stable enough.
4. Bone graft is not necessary but in valgus deformity the correctuve osteotomy should be performed to correct the valgus.
The skin is closed,the long arm cast is put and change in 2 weeks interval until bone union.
The measurement will be
1. The union rate
2. The carrying angle , Baumann angle,shaft condylar angle
3. ROM
4. Complication of surgery such as infection,AVN of troclear etc.
