“…The complexity of a femoral reconstruction depends on the number of previous arthroplasties and extent of loss of bone stock. The American Academy of Orthopaedic Surgeons proposed a classification system whereby femoral defects are categorized as segmental deficiencies (any loss of bone in the supporting cortical shell of the femur), cavitary defects (containing lesions representing an excavation of the cancellous or endosteal cortical bone without violation of the outer cortical shell), or combined segmental and cavitary defects (19).…”

“…We obtained plain anteroposterior (AP) and lateral views of the hip and femur and CT scans, if needed, for preoperative planning and followup. We classified preoperative femoral bony defects according to the American Academy of Orthopaedic Surgeons Committee on the Hip system [10] as follows: 45 Type II, six Type III, one Type IV, one Type V, and six Type VI. Overall, 31% of the preoperative femoral defects were limited to Level I (lesser trochanter), 56% had cortical damage extending to Level II (\ 10 cm below the lesser trochanter), and 14% had cortical damage extending to Level III ([ 10 cm below the lesser trochanter).…”

Revision after failed THA resulting from loosening of the femoral component can be challenging even for experienced surgeons. Aseptic loosening usually is associated with some degree of bone loss. We asked whether the Zweymüller SLR-Plus 1 , along with allograft reconstruction of the deficient femoral bone stock, would provide survivorship, osseointegration, and stability similar to or better than previously reported implants for femoral revision. We retrospectively reviewed 69 selected patients (70 hips) who underwent revision of the femoral component using the SLR-Plus 1 stem during a 10-year period. The indications for revision included aseptic and septic failure of biologic fixation, incorrect implantation, and periprosthetic fracture. Seven patients died and four were lost to followup. Fifty-eight of the 69 patients (59 hips) were available at a mean 8.3 ± 2.7 years (range, 4-14 years) after revision surgery. There were 14 men and 44 women (mean age, 69 years; range, 42-89 years). Four stems (7%) were rerevised. With rerevision for aseptic reasons, the survival at 10 years was 95% (95% confidence interval, 86%-

“…Various classification systems have been proposed to attempt to address this surgical challenge [1,7,9,10,12,15,19,29]. One commonly used classification is the Paprosky classification for femoral bone loss, which is a categorization based on bone loss location and degree of severity, and proposes a treatment algorithm for surgical reconstruction based on these measures ( Fig.…”
