Bosworth hip shelf arthroplasty in adult dysplastic hips: ten to twenty three year results.

Purpose: Hip shelf arthroplasty is currently considered to be a salvage procedure. The aim of the study is to present outcomes of Bosworth hip shelf arthroplasty in adolescent dysplastic hips with a minimum ten-year follow-up.

Methods: The basic group comprised 25 hips in 18 patients with the mean age of 31 years (range, 16-52) at the time of operation.

Operative treatment of avascular necrosis of the femoral head after proximal femur fractures in adolescents.

Purpose: Our aim was to assess operative treatment for post-traumatic avascular necrosis of the femoral head (ANFH) in adolescents.

Methods: Eleven patients with an average age of 17 (range 14-26) years were operated up on for ANFH after proximal femoral fractures. The average interval between injury and reconstructive surgery was four (range two to eight) years.

Valgus intertrochanteric osteotomy for coxa vara of Bucholz-Ogden Types II and III in patients older than 30 years.

Background: Ischemic necrosis of the proximal femur resulting in coxa vara is a severe iatrogenous complication of the treatment of developmental dysplasia of the hip (DDH). Severe relative overgrowth of the greater trochanter and reduction of the neck result in insufficiency of hip abductors. Unequal limb length causes obliquity of the pelvis, compensatory scoliosis of the lumbar spine and valgus deformity of the ipsilateral knee.

Operative treatment of avascular necrosis of the femoral head after slipped capital femoral epiphysis.

Purpose: The aim of the study was assessment of the medium-term outcome of operative treatment of avascular necrosis of the femoral head (ANFH) after slipped capital femoral epiphysis (SCFE).

Materials And Methods: Five patients were treated with valgus-flexion intertrochanteric osteotomy (VFITO) for partial ANFH that developed after operative treatment. Their average age at the time of slip was 12.

Management of ischemic deformity after the treatment of developmental dysplasia of the hip.

Long-term results of 69 hip operations for deformities due to avascular necrosis following the conservative treatment of the hip dysplasia were evaluated. The authors' technique of intertrochanteric valgus osteotomy allows for simultaneously handling of varus deformity and shortening of the femoral neck, fusion of the greater trochanter, and correction of increased femoral anteversion, if necessary. This type of surgery was used in children with Buchholz-Ogden type III deformity starting from 3 years of age until adolescence.
