Abstract
Purpose of Study
To assess the results of Revision Hip Surgery in which a less invasive technique was utilized in situations where a number of different options was available.
Method
The authors rely on an experience of 3,445 hip arthroplasties by a single surgeon over a period of 20 years, of which approximately 20% were revision cases. Of these 617 cases, we report on 175 in which a minimally invasive option was taken. This does not apply to the skin incision, as all cases were adequately exposed. We have adopted this term to describe cases in which a surgical options was taken that resulted in the least morbidity and the shortest surgical time. We postulated that would lead to the best outcomes with the least complications.
Acetabular revisions: 1) Isolated polyethylene exchange. 2) Liner revision with cement technique in cases of cup malposition or poor locking mechanism. 3) Revision of cup with a primary prosthesis with significant medial bone loss.
Stem revisions: 1) Cement on cement technique. 2) Strut graft and primary stem.
Results
We found a very low complication rate utilizing these methods: Fatal pulmonary emboli: 0 Sepsis: 2 Dislocations 3 Repeat revisions 3
Conclusion
Revision surgery offers many challenges that tend to be compounded with successive operations. We believe that good results can be achieved when a philosophy of minimally invasive surgery is adopted.
