Introduction:
Spondyloepiphyseal dysplasia tarda with progressive arthropathy (SEDT-PA) is a rare inherited dysfunction with autosomal recessive inheritance. SEDT-PA is also named as progressive pseudorheumatoid arthropathy of childhood as it is associated with multiple joint contractures and arthritis. We report a case of SEDT-PA managed with bilateral stage total hip arthroplasty.
Case report:
A 22-year-old lady presented with severe bilateral hip arthritis. Based on her clinical and radiological features described in this article, she was diagnosed as having SEDT-PA. She was managed with bilateral stage total hip arthroplasty. The pre-operative planning and technical challenges of performing this procedure have been described.
Conclusion:
Dysfunctions originally of genetic origin like spondyloepiphyseal dysplasia tarda mimics and is commonly misdiagnosed as juvenile chronic arthritis. These patients have disabling early-onset hip arthritis which requires surgery. Arthroplasty is challenging in these patients because of the low proximal femur offset but good results can be obtained after thorough pre-operative planning to tackle intraoperative difficulties.
