Other devices employed include the spica cast, particularly following surgical closed reduction. A few weeks in traction can be used as part of a treatment plan.

In older children the hip abductor and iliopsoas muscles have to be treated surgically because they adapt to the dislocated joint position (contracture). Braces and splints are often used following either of these methods to continue treatment. Although some children "outgrow" untreated mild hip dysplasia and some forms of untreated dysplasia cause little or no impairment of quality of life, studies have as yet been unable to find a method of predicting outcomes. On the other hand, it has often been documented that starting treatment late leads to complications and ends in poor.

Stem cells
One avenue of research is using stem cells. They are applied in grafting (bone grafting) or by seeding porous arthroplasty prosthesis with autologous fibroblasts or chondrocyte progenitor cells to assist in firmly anchoring the artificial material in the bone bed.

Hip replacement and osteotomy
Hip dysplasia is often cited as causing osteoarthritis of the hip at a comparatively young age. Dislocated load bearing surfaces lead to increased and unusual wear. Although there are studies that contradict these findings.  Subsequent treatment with total hip arthroplasty (Hip replacement) is complicated by a need for revision surgery (replacing the artificial joint) due to skeletal changes as the body matures, loosening/wear or bone resorption.
Osteotomies are either used in conjunction with arthroplasty or by themselves to correct misalignment.
