“…5 Use of two corkscrew devices, as described by Judas et al, mostly closely resembles the described technique by inducing a distraction force across the component-cement interface. 7 In our experience the disadvantage of this technique is the un-predictability of the separation of the cup from the cement mantle.…”

“…Previous techniques offer different approaches this problem including the use of pneumatic devices, burrs and a variety of reamers, drills and corkscrews. [3][4][5][6][7] Polymethylmethacrylate bone cement has high load to failure in compression, however in tension this is reduced significantly. This technique allows the controlled separation of the implantcement interface under tension to effectively loosening the acetabular component.…”

“…The acetabular component should be exposed circumferentially before the process of extracting implants. The polyethylene acetabular liner can be firmly screwed and removed by cork-screws [5] or other tools. The detail of the acetabular metal cup is clearly exposed after removing the liner.…”

Removing well-fixed acetabular components can be a challenge for orthopaedic surgeons in revision of total hip arthroplasty. Acetabular bone loss, fracture, and other complications occurred in extracting implants may result in instability and fail of revision. Thus, instruments are developed to avoid such complications. We report a simple technique by drilling a tunnel on the superolateral quadrant of acetabulum and using an offset staff to remove acetabular components without many matching units. The procedure of removing well-fixed acetabular components is a simple, efficient, inexpensive, bone stock preserving technique.

“…The existing liner is removed by previously described techniques, depending on whether it is cemented or pressfit. 15 Next, the inner surface of the preexisting shell is cleaned and prepared for cementation of the second cup. If the existing cup is solid backed, a high-speed metal-cutting burr is used to score the inner surface and to create multiple grooves to promote cement interdigitation (►Fig.…”

Revision Total Hip Arthroplasty in the Setting of a Well-Fixed Cup: Early Report on the Cup-in-Cup Technique

et al. 2017

When faced with a well-fixed acetabular component during revision total hip arthroplasty (THA) in the setting of recurrent instability, reconstructive options are limited, and consequences can prove dire if removal leads to severe bone loss or pelvic discontinuity. Our aims are to report the surgical technique, early survivorship, radiographic improvements, and complications on a consecutive, retrospective series of 13 hips in 12 patients who were treated with a cup-in-cup surgical technique to address multiply recurrent dislocations in the setting of a well-fixed cup. If determined to be stable and acceptably positioned upon intraoperative assessment, the acetabular component is retained, a second shell is cemented into the preexisting cup, and a dual mobility or standard polyethylene liner bearing is utilized. At 2-year minimum follow-up, the cup-in-cup arthroplasty exhibited an overall 85% survivorship. Two subjects required subsequent revisions: one for infection and one for ongoing instability in the setting of general noncompliance. No revisions were performed for loosening of the cup-in-cup interface. The median affected leg length was increased by 2.8 mm (p = 0.04) and horizontal offset improved by an average of 6.9 mm (p < 0.001). There were a total of four dislocations in two subjects after cup-in-cup revision arthroplasty with no failures at the cup–cup cement interface. Our series demonstrates acceptable early outcomes in terms of improved stability and decreasing the need for further revision surgery while utilizing the cup-in-cup revision arthroplasty technique in situations of recurrent dislocations.
