Background:
To break or not to break-That is the question that has been asked in pediatric traumatology for many years regarding the treatment of greenstick fractures of the diaphyseal forearm shaft.
Objective:
The frequency of greenstick fractures of the forearm shaft in children and adolescents; the influence of breaking the fracture on the refracture rate.
Methods:
Analysis and discussion of relevant articles, analysis of the refracture rate of pediatric greenstick fractures of the forearm shaft in our own patient population.
Results:
Greenstick fractures frequently occur in the area of the forearm shaft and incomplete consolidation leads to an increased refracture rate. In the patient collective of the authors of 420 children with greenstick fractures of the diaphyseal forearm, there was a refracture rate of 9.5%; however, the rate for non-completed fractures was significantly higher compared to the group with completed fractures (15.2% vs. 3%). While in the subgroup of conservatively treated fractures (n = 234), breaking the intact cortex significantly reduced the refracture rate, breaking the intact cortical bone during surgical treatment with elastic stable intramedullary nailing (ESIN) did not change the refracture rate.
Conclusion:
As part of the conservative treatment of greenstick fractures of the diaphyseal forearm, completing the fracture can be recommended in order to lower the refracture rate. Completing the fracture does not appear to be necessary during surgical treatment using ESIN.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

01:17Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...
01:27Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
