Introduction:
Modem indications for use of cemented or uncemented implants in revision hip arthroplasty are comparable. The use of bone cement provides predictable short term results, but the lack of osteointegration deteriorates its long term durability. Uncemented implants undergo osteointegration, but reduced contact with host bone may cause early loosening. Modular porous tantalum implants are highly osteointegrative, and the availability of bone stock augments increases the versatility of this system.
Material And Methods:
The study group consisted of 20 patients (21 hips) who underwent a revision hip arthroplasty using Trabecular Metal acetabular revision system. The follow-up period was between 7 and 31 months (average 20 months). All patients were evaluated with HHS and conventional radiography.
Results:
The mean HHS increased form40.45 (range 18.74-56.65) preoperatively to 78.8 (56.5-96) at the last follow-up. No mechanical failures, nor septic complications were noted.
