Abnormal femoral neck anteversion, previous proximal femoral osteotomies, and small femoral canals with metaphyseal/diaphyseal mismatch are commonly seen in patients with developmental dysplasia of the hip (DDH) and are ideal indications for using a modular femoral stem. The torsional stability of the fluted modular stern makes it the implant of choice for subtrochanteric osteotomy stabilization for reduction of high-riding DDH. Modularity optimizes proximal and distal implant stability while permitting adjustments to anteversion, offset, and leg length to provide custom biomechanical reconstruction of the DDH hip. Clinical results with few complications can be achieved when using this stem in complex DDH surgery.

    Background: Residual acetabular dysplasia of the hip in most patients can be corrected by periacetabular osteotomy. However, some patients have intraarticular abnormalities causing insufficient coverage, containment or congruency after periacetabular osteotomy, or extraarticular abnormalities...

    Background: Modern hip resurfacing implants may increase stability and preserve more bone than conventional total hip arthroplasty. The purpose of this retrospective study was to analyze the mid-term results in a consecutive series of middle-aged patients with developmental dysplasia of the hip...

    Background: Dysfunction of the hip secondary to dysplasia is a complex problem that includes excessive stresses on the articular cartilage, dynamic hip instability, and muscular fatigue, eventually leading to degenerative arthritis if left uncorrected. Mechanical stress on the dysplastic hip has...

    Background: The Bernese periacetabular osteotomy (PAO) is commonly used to surgically treat residual acetabular dysplasia.

    Implantation of a femoral stem in a dysplastic femur poses many problems. Most common abnormalities are excessive anteversion and valgus angle of the femoral neck. This makes it impossible to use conventional stems. Suitable options are distally fixed stems with small metaphysis or proximally...

    Background: Although periacetabular osteotomy (PAO) for developmental dysplasia of the hip (DDH) provides conceptual advantages compared with other osteotomies and reportedly is associated with joint survivorship of 60% at 20 years, the beneficial effect of proper acetabular reorientation with...

    Background: Developmental dysplasia of the hip (DDH) is common, affecting 7.3 per 1000 births in South Australia. Clinical screening programmes exist to identify the condition early to gain the maximum benefit from early treatment. Although these screening programmes are effective, there are...
