False joint - what is it?
When correcting a bone fracture, there are conditions when the bones do not fuse together, but remain mobile with mobility limited by the surrounding soft tissues. Moving places in the bone that do not meet a functional purpose are called a pseudarthrosis.
The causes of a false joint are different:
- Congenital anomalies
- Multiple fractures of the same bone
- Nonunited fractures.
Most often, a pseudarthrosis is formed in the treatment of closed fractures, when soft tissues fall between the fragments of bones, the immobilizing bandage (fastening) is removed early, with early loads on the broken and restored bone, with purulent inflammation in the fracture area, with excessive divergence of the broken parts, in violation blood supply to bone tissue in the area of the fracture, which leads to a failure in the regeneration processes, with splinter fractures and displacement of fragments.
False joint signs and diagnostics:
- Abnormal bone mobility in the area of the treated fracture,
- The X-ray shows the absence of callus, the roundness of the end portions of the bone fragments.
Treatment for a pseudarthrosis is associated with surgical intervention and is based on osteosynthesis, resection of the edges of the bone tissue and fusion of the new bone with lengthening or using bone grafting.
