Acetabular Fracture Reduction Assessment

NCT04073329 | Unknown

Brief Summary

It is widely accepted in the literature that quality of acetabular fracture reduction is one of the most important factor for the outcome. To obtain best results, anatomical reduction has to be obtained. Intra-operative radiographic assessment depends mainly on plain x-ray. Plain x-ray alone is not enough for post-operative assessment as it depends mainly on reduction of the dome with concentricity of the hip.

Conditions

Acetabular Fracture

Outcome Measures

Primary Outcomes (1)

• Ability of CT scans and plain radiographs to detect residual articular steps and gaps after healing of acetabular fractures managed by open reduction and internal fixation.

  measurement was used to grade quality of reduction according to Matta's system . In accordance with prior studies, adequate (or anatomic) reductions with 0-1 mm of displacement were compared to inadequate (imperfect or poor) reductions with \> 1 mm displacement . For the CT-based method, postoperative pre-digital (prior to 2000) and digital CT images were independently assessed in the axial, sagittal, and coronal planes, and residual gap and step displacement were measured along the articular surface at the level of the weight-bearing dome. Adequate reductions on postoperative CT were defined as \< 1 mm step and \< 5 mm gap displacement and inadequate reductions as ≥ 1 mm step and/or ≥ 5 mm gap displacement.
