Primary single stage Total Hip Arthroplasty in a patient 40 years post traumatic Hip dysplasia, a case report

INTRODUCTION: Hip dysplasia refers to an abnormal development of size, shape, or organization of the femoral head, acetabulum, or both. Managing acetabular dysplasia is very challenging in arthroplasty especially in traumatic hip dysplasia case. Mostly, hip dysplasia cases need a special implant, procedure and techniques. CASE PRESENTATION: We performed primary Total Hip Arthroplasty (THA) + partial tenotomy of hamstring, iliotibial band, hip abductor in a 73 year old male. His main complaint was that he was unable to sit due to an increasingly intense pain since 3 months ago and he has been unable to walk properly since 40 years ago when he had a major traffic accident and received inadequate treatment. The procedure had been successfully done using a well press-fit cementless acetabular cup and a cementless narrow stem application 1 cm on leg length discrepancy (LLD). CONCLUSION: Preoperative planning, surgical techniques and a post-surgery rehabilitation are the key to a successful management in this case.
