Plaster fixation is possible, but you need to take a film to check the fracture alignment within two weeks. If the alignment is not good, you need further treatment (because you have an oblique fracture and an unstable fracture).

Because your wound has not healed, you can also choose the same treatment method, that is, external fixator, which has the advantages of stable fracture and convenient wound healing. The disadvantage is that it is very inconvenient. Internal fixation can be used after wound healing.
