Bernese periacetabular osteotomy
Published in K. Mohan Iyer, Hip Preservation Techniques, 2019
For patients who have complex deformities, additional surgery will give them a better outcome than only performing PAO. For instance, surgical dislocation and intra-articular surgery can be used in a deformed or avulsed acetabular labrum.13,14 Osteochondroplasty and femoral head reduction can be used in deformity of the femoral head. Intertrochanteric or femoral neck osteotomy can be used in the correction of coxa vara and coxa valga. Derotation osteotomy can be used in the abnormal femoral neck ante version.15–18 The other category of factors is surgery-related factors. Most of them concern acetabulum repositioning, such as under- or overcorrection of the acetabulum, abnormal acetabular version, and lateralized hip center.19 These factors can be resolved by the routinization and refinement of the PAO procedure.
Paralytic dislocation of the hip – cerebral palsy

In order to correct the coxa valga and the anteversion, an intertrochanteric or subtrochanteric osteotomy is performed. Although pre-operative measurement of the degree of coxa valga and the anteversion by appropriate imaging methods gives an insight into the magnitude of these deformities, often this may not be essential. In the operating theatre the hip is held in abduction and internal rotation and the best position that shows a concentric reduction is confirmed by radiography. The thigh is held in the chosen position of abduction and internal rotation and the femoral head is temporarily transfixed to the acetabulum with a stout K-wire. The femoral osteotomy is then performed and the distal fragment is adducted and externally rotated until the limb is in the neutral position. The fragments are fixed with a plate after which the K-wire is removed.

Morquio’s syndrome presents several orthopaedic problems. Genu valgum may need correction by femoral osteotomy, though this should be delayed until growth has ceased. Coxa valga and subluxation of the hips, if symmetrical, may cause little disability; unilateral subluxation may need femoral or acetabular osteotomy. Atlantoaxial instability may threaten the cord and require occipitocervical fusion.
Extra-articular hip impingement: clinical presentation, radiographic findings and surgical treatment outcomes
Published in The Physician and Sportsmedicine, 2019
In the less common setting of coxa valga and excessive femoral anteversion and resultant posterior trochanteric-pelvic impingement, the proposed treatment includes a varus producing proximal femoral osteotomy with derotation [32]. While this procedure has been used extensively for the treatment of patients with cerebral palsy with recurrent hip subluxation, there are no available clinical series reporting on the outcomes of this procedure for this specific diagnosis.

In our study, occurrence of type II osteonecrosis was not associated with overgrowth. It could be partly because the deformity in type II osteonecrosis is caput valgum rather than coxa valga and the center of rotation is close to the top of the femoral head (Shin et al. 2017). Moreover, severe type II osteonecrosis shortens the femoral neck, which may compensate for the lengthening effect of the proximal femoral valgus.
