How do you classify bony defects in a THR
AAOS
Acetabular 1 - Segmental deficiency 2 - Cavitatory deficiency (intact A & P columns) 3 - Combined deficiency 4 - Pelvic discontinuity 5 - Arthrodesis
Femur 1 - Segmental deficiency 2 - Cavitatory deficiency 2a - Cavitatory only 2b - Ectasia (femoral expansion) 3 - Combined deficiency 4 - Malalignment 5 - Stenosis 6 - Femoral discontinuity
Segmental needs Structural BG
Cavitatory needs non-structural BG
P/F discontinuity requires Healing Bone Bridgjng Fixtion
Paprosky
Based on severity of bone loss and ability to obtain cementless fixation
Based on integrity of
Superior migration of hip centre, ischial osteolysis, acetabular teardrop osteolysis, and position of implant relative to Kohler’s line
1) TYPE 1
Rim intact with no significant rim distortion. Columns intact acetabulum hemispherical. Small focal areas contained bone loss. Kohler line not violated. No migration of component and no osteolysis Hemispherical uncemented implant
2) TYPE 2
2a – Columns and rim intact. Bone loss superior and medial. Hip centre migrated superiorly. Migration 3cm migration, moderate ischial lysis and intact Kohler line
Hemispherical cup will have 1/2 circumference
Failed component has migrated superiorly and medially
