Overview

3D CT may aid precise planning for rotational acetabular osteotomy; case-level data leaves optimal shift direction open for prospective validation.

Study Design

Type

Observational (n=6)

Structured PICO

Does three-dimensional CT reconstruction improve preoperative and postoperative assessment of rotational acetabular osteotomy in children with dysplastic hips?

P
Population
6 dysplastic hips in children evaluated before and after rotational acetabular osteotomy using 3D CT reconstruction.
E
Exposure
Three-dimensional computed tomography (CT) reconstruction before and after rotational acetabular osteotomy
O
Outcome
Three-dimensional relationship between the acetabulum and femoral head (acetabular coverage)surrogate

3D CT reconstruction provides exact anatomic information on acetabular coverage, aiding precise operative planning for rotational acetabular osteotomy in dysplastic hips.

Cite This Study

Azuma et al. (1990) conducted an observational in Dysplastic hips (n=6). Three-dimensional computed tomography (CT) reconstruction was evaluated on Anatomic information on acetabular coverage and relationship between acetabulum and femoral head. Three-dimensional CT reconstruction of 6 dysplastic hips revealed potential dangers of anterolateral rotational shift when marked posterior deficiency is present, suggesting a lateral shift may be safer.
