Total hip replacement in difficult acetabulum planning and management

Authors

Abstract

Background
Total hip replacement improves pain and quality of life in people with hip arthritis. Total hip replacement is a successful orthopedic procedure. Dysplastic or difficult acetabulum is a general definition that means abnormal hip socket that leads to uncoverage of the head femur and excessive pressure on the rim of the hip socket including many diagnoses as aseptic loosening, acetabular protrusion, neglected developmental hip dysplasia, posttraumatic acetabular malunion or advanced osteoarthritis and revision of failed hemi/total arthroplasty, etc…
Aim
To plan and manage difficult acetabulum component in THA and to evaluate the clinical and radiological outcomes of these patients with different diagnoses.
Patients and methods
Twenty cases were enrolled in this investigation.
Results
The duration of hospitalization varied from 2 to 5 days, with a mean of 2.95 ± 0.921 days. The return to exercise varied from 2 to 5 months, with a mean of 3.38 ± 0.865 weeks. A statistically significant difference (P=0.0002) between patient satisfaction and leg length discrepancy indicates that the equal group is more satisfied.
Conclusion
In the treatment of problematic acetabulum components in THA, cementless components are effective and a viable therapeutic choice. The strategy related to shorter hospital stays and a speedy return to normal activity. Further comparison researches with bigger sample sizes and longer follow-up periods are required to corroborate our findings and uncover adverse event risk factors.
