Outcome Measures

Primary Outcomes (2)

  • Radiological Fracture Union

    Radiological fracture union is considered based on the presence of bridging callus (3/4 of cortices) in both anteroposterior and lateral views in x rays.

    According to each group ranging from 5 months in group 1, 7 in group 2 and up to 12 months in group 3

  • Clinical Fracture Union

    Clinical fracture union assessment is based on presence or absence of pain at the fracture site.

    According to each group ranging from 4 months in group 1, 6 in group 2 and up to 11 months in group 3.

Study Arms (4)

NUSS group 1

ACTIVE COMPARATOR
Procedure: Improving the stability and re-fixation with different modalities

NUSS group 2

ACTIVE COMPARATOR
Procedure: Re-fixation with biological stimulation

NUSS group 3

ACTIVE COMPARATOR
Procedure: complex care with non-union resection and bone reconstruction

NUSS group 4

ACTIVE COMPARATOR
Procedure: Amputation

Interventions

Improving the stability and re-fixation with different modalities such as exchange plate with longer plate, intramedullary nailing, exchange nailing with larger diameter, plating over nail or dynamization of intramedullary nail.

NUSS group 1

Re-fixation with biological stimulation such as bone grafting, either with plate and bone graft, plate over nail and graft, or with external fixation with LRS or Ilizarov and grafting in one stage or two stages.

NUSS group 2

complex care with non-union resection and bone reconstruction, including resection of the non-union and dealing with the defect with bone transport, either direct transport or staged with cement spacer and later bone transport, Masquelet technique or acute compression and lengthening with another osteotomy.

NUSS group 3
AmputationPROCEDURE

Amputation with consideration of prosthesis.

NUSS group 4
