The augment-and-modular-cage revision system for reconstruction of severe acetabular defects—two-year clinical and radiographic results

Abstract: Purpose Acetabular revision of failed total hip arthroplasty (THA) is often associated with severe bone loss. Therefore, a variety of revision implant systems has been developed during recent years, with the augment-and-modular-cage system being one of the newest additions to this portfolio. Together with biologic downsizing by means of impaction bone grafting, this uncemented system promises a high modularity and versatility to treat all acetabular defects up to Paprosky types IIIa and IIIb without pelvic dis… Show more

“…Several studies demonstrated that impacting bone grafting in combination with acetabular components was widely used in revision hip arthroplasy when significant bone defects exists [14]. The technique of impacting bone grafting would take the place of the bulk grafts gradually because of low osseointegration potential of bulk grafts [8]. Garcia CT et al…”

“…We applied the modified Harris Hip Score (mHHS) for the clinical and functional evaluation, and the mHHS was considered as the primary outcome parameter and classified as previous described [17]. In addition, measurements like University of California, Los Angeles (UCLA) activity score [18] and Short Form 36 (SF-36) [8] were recorded. The distance from the anterior superior iliac spine to the medial maleolus was measured as the leg length, and the difference between both lower extremities was calculated and defined as limblength discrepancy (LLD) [17,18].…”

“…Means of augmentation can include oblong cups, cranial socket systems, augment-and-cup and augment-and-cage designs. Recently, promising early results for an augmentand-modular-cage-design have been published showing an improvement of clinical function and patient reported outcome as well as efficient reconstruction of the acetabular center of rotation [23]. In cases of severe bone loss to the dorsal column anatomic flanges and/or iliac pegs should be added to the construct.…”
