42-C1 Complex diaphyseal fracture with reducible wedges


42-C1 are complex diaphyseal fractures with reconstructible wedges.

The main feature differentiating C1 from C3 fractures is the fact that the wedges are reconstructible in C1 fractures and non-reconstructible in C3.


42-C1 type fractures have a fractured fibula.


General considerations

42-C type fractures are complex diaphyseal fractures. They differ from the B-Type fractures by the fact that, once reconstructed, the two main fragments do not have direct contact with each other.

The fracture classification by definition states that B1, B2, C1 and C2 fracture are anatomically reconstructible fractures, whereas B3 and C3 are not reconstructible.

Note: B1, B2, C1 and C2 fractures, depending on the sizes of the fragments, may best be managed like a non-reconstructible fracture.


42-C fractures are generally caused by high energy trauma, often road traffic accidents or gunshot wounds.

Clinical signs

Clinical signs observed in 42-C fractures are:

  • Edema of the region
  • Abnormal movement in the tibia shaft
  • Pain
  • Non weight bearing on the limb
  • Soft tissue damage


Craniocaudal and lateral radiographic views are needed.
