Background: Total hip arthroplasty (THA) is presently the quality surgical choice for hip osteoarthritis secondary to developmental hip dysplasia (DDH); it may be extraordinarily challenging, due to the hypoplasic proximal metaphysis, pathological anteversion, and immoderate cervico-diaphyseal perspective of the neck at the femoral facet. The reason of this retrospective study become to evaluate the lengthy-time period survival and medical and radiological outcomes of Conus uncemented stems, implanted in patients affected by hip osteoarthritis with Crowe now not-type IV secondary to DDH. Material and technique: This was a retrospective study has conducted in Department of Orthopedic, UHC sadar, Mymensing. During the period of June 2013 and july 2021. We identified 96 consecutive THAs executed for DDH in 57 women and 26 men, with an average age of 53 years in a single center. 13 sufferers underwent bilateral hip replacement. The patients’ suggest frame mass index changed into 29. Eight kg/m2 (range 27.1–35.6 kg/m2). The most important symptoms for surgical treatment had been intense hip pain and huge purposeful impairment: the preoperative Harris Hip Score turned into 29.5 on average (variety 22–61). Radiologically, 8 hips were categorized as Crowe I, 41 hips as Crowe II, and 47 hips as Crowe III. In all cases, we implanted the Wagner femoral cone prosthesis using the direct lateral technique; within the attempt to reestablish local hip biomechanics, sixty six stems have been one hundred thirty five° and 34 were one hundred twenty five°. Results: The imply observe-up of the take a look at was 11.7 years (range 2.2–21.Eight years). Harris Hip Score expanded to a median value of 71.5 factors (range 52–ninety three points). Radiographic evaluation verified osteointegration of the implant with strong bone increase discovered on the stem–endosteum interface; signs and symptoms of bone readaptation and thinning of the femoral calcar were present in nine hips. ............
