Cementless Total Hip Arthroplasty for Adult Patients With Sequelae From Childhood Hip Infection: A Medium-Term Follow-Up Study

Total hip arthroplasty in patients with common pediatric hip orthopedic pathology

Purpose

Literature regarding total hip arthroplasty for pediatric hip diseases is scarce. This review aims to portray the various orthopedic conditions of childhood that can lead to significant impairment of the hip joint and, ultimately, to total hip arthroplasty in adolescence and adulthood.

Methods

In total, 61 out of 3666 articles were selected according to (1) the diagnosis of one of the 12 pediatric hip pathologies (Legg-Perthes-Calvé disease, developmental dysplasia of the hip, slipped capital femoral epiphysis, neuromuscular hip dysplasia, post-traumatic avascular necrosis of the proximal femur, juvenile rheumatoid arthritis, achondroplasia, spondyloepiphyseal dysplasia, mucopolysaccharidosis, mucolipidosis, hip infections, and tumors) that required total hip arthroplasty; (2) minimum follow-up of 16 months; (3) assessed outcome with a clinical or radiologic score; (4) Methodological Items for Non-Randomized Studies quality score of 9 or higher. The following information for each pathology was retrieved: mean age at total hip arthroplasty, reason for total hip arthroplasty, type of total hip arthroplasty, surgical technique, mean follow-up, and outcomes.

Results

Overall, the mean age at total hip arthroplasty for pediatric hip disease is in the sixth and seventh decade, except for tumors and skeletal dysplasias. The reason for performing total hip arthroplasty is often osteoarthrosis and abnormal anatomy. Prosthesis types change based on patient's conditions and technological advances; custom-made implants are used for tumors, juvenile rheumatoid arthritis, and skeletal dysplasias; for other diseases, the most frequent are modular cementless implants. Outcomes are generally good, and all studies portray functional and pain improvements.

Conclusion

Total hip arthroplasty is performed more frequently than in the past in patients with pediatric hip pathologies; it enhances patients' quality of life by reducing pain and improving function. However, revision rate in these patients is not negligible.

Primary Total Hip Replacement in a Case of Unilateral Hypo Plastic Proximal Femur - A Case Report

Introduction:

Primary total hip replacement in hypo plastic proximal femur is difficult due to the presence of a small canal, soft- tissue contracture, fragility of bone, and poor femoral cement mantle when used. Intraoperatively, there could be occurrence of fracture of the femur, inadequate fit, and fill with cement less femoral component.

It is found unilaterally in cases of osteonecrosis of femoral head, post- traumatic, and in sequelae of childhood septic arthritis.

Case Report:

A 45-year- old male patient presented to the OPD with complaints of pain in the left hip and difficulty in walking since for 4 years. The patient had a history of fever and swelling over the left hip in childhood with no treatment taken for the same. X-ray of pelvis with both hips showed deformed femoral head, short neck, narrow femoral canal (Grade 1 Dorr), and arthritic changes in acetabulum. We managed with total hip replacement using Wagner cone stem. Postoperatively, the patient is having good range of motion and having no difficulty in walking and weight- bearing. Functional outcome is good as per Harris hip score.

Conclusion:

Total hip replacement in hypo plastic femur with arthritis is always a challenging problem. It requires surgical expertise and proper implant selection and pre-operative planning, which prevents intraoperative and post-operative complications. Wagner cone stem is a very good option in managing this type of patients.
