“…Zhang, et al described a technique of drilling a tunnel on the postero-superior quadrant of acetabulum, from the bone cortex to the surface of acetabular metal cup [11]. Whilst this technique may seem relatively simple, it can result in weakening of the posterior wall of the acetabulum.…”

Removing well-fixed porous cementless acetabular components in revision Total Hip arthroplasty can be a surgical challenge for Orthopaedic surgeons. Forceful removal can result in loss of bone stock. Acetabular wall fracture is a real risk associated with extracting well-fixed cementless acetabular components, especially with certain instruments. Extraction of a well-fixed porous cementless acetabular component with relative ease can be achieved with the technique described.I report a technique of disrupting the implant-bone interface. This technique is simple and safe, with no risk of complications like bone loss or acetabular wall fractures. Acetabular bone stock is preserved, making it easier to implant revision components.To my knowledge, this technique has never been described before. I have used this technique in my practice for the extraction of well-fixed porous acetabular components for a variety of indications. The results have been reproducible with no complications, like acetabular wall fractures or bone loss, requiring adjuvant fixation with augments.

“…6,19 In the setting of revision THA, the double socket technique may mitigate bone loss, prolonged operative time, blood loss, and debris generation associated with the replacement of incompatible well-fixed acetabular shells or those with failed locking mechanisms. 10,20 Furthermore, the double socket technique provides an opportunity to perform limited adjustments in liner angulation and offset relative to the well-fixed shell, thereby attaining a cup orientation and position that are more conducive to hip stability. 10,15 The results of the current study demonstrated that in contrast to our initial hypothesis, a significant…”

“…6,7 While poor acetabular component position may predispose a patient to recurrent instability after revision THA, the removal of well-fixed yet sub-optimally placed shells is associated with significant morbidity and bone loss. 5,8,9 Therefore, the cementation of the outer metallic liner of DM cups to a well-fixed acetabular shell (metal-in-metal constructs), also known as the double socket technique, is an alternative that has progressively gained recognition. 5,8,10 This technique allows partial correction of the acetabular position and orientation.…”

Cementing metallic liners into well-fixed acetabular shells facilitates utilizing dualmobility cups in revision total hip arthroplasty without shell replacement. The current biomechanical study investigated the effect of increasing cemented liner (a) inclination; and (b) offset on the cement retention strength measured as the leverout moment at cement failure. Eighteen metallic liner prototypes were cemented into cluster-hole acetabular shells at variable inclinations (0°, 10°, and 20°) and offsets (0 and 10 mm) relative to the enclosing acetabular shell (6 groups; n = 3 constructs per group). The constructs were connected to a material testing frame, and lever-out failure moments were tested through an established protocol. Failure occurred at the liner-cement interface (18/18). There was no correlation between liner inclination and the lever-out failure moment (r = −0.327, P = .185). Liner offset demonstrated a strong negative correlation to mean lever-out failure moments (r = −0.788, P < .001). There was no significant difference between mean lever-out failure moments at variable liner inclinations, regardless of offset (P = .358). Greater liner offset was associated with diminished mean lever-out failure moments (P < .001). Compared with neutral (0°inclination, 0 mm offset), the maximum inclination and offset group had the lowest mean lever-out failure moment (P = .011). Cemented metal-in-metal constructs are significantly affected by the liner positioning. While a correlation between liner inclination and cement retention strength could not be asserted, cement retention strength is significantly diminished by increased liner offset.
