A fluted femoral stem is designed to provide diaphyseal rotational stability through multiple longitudinally oriented flutes with varying numbers and positions, depending on the manufacturer. These fluted stems may be…
Varus intertrochanteric osteotomy involves the reorientation of the proximal femur in order to improve femoral head coverage and joint congruency. It may serve either as a reconstruction or salvage operation….
The modified Dunn procedure is an open realignment of the capital femoral epiphysis performed through a surgical dislocation approach.18 Like the original Dunn osteotomy, the modified Dunn corrects a slipped…
Coxa saltans is a term popularized by Allen and various co-authors.1 Encompasses three types • Internal type (iliopsoas tendon) • External type (iliotibial band) • Intra-articular type was originally attributed to diverse intra-articular…
Substantial bone loss and bone defects are among the most challenging problems faced by surgeons performing revision knee arthroplasty. Tibial bone loss in failed total knee arthroplasty (TKA) is a…
Acetabular bone deficiency may occur primarily (eg, dysplasia, inflammatory arthritis, or seronegative arthropathy) or secondarily (eg, aseptic or septic loosening of acetabular components, osteolysis, trauma, or iatrogenic loss during removal…
Well-fixed femoral and acetabular components often must be removed during revision total hip arthroplasty (THA). Determine which well-fixed components should be removed and which should be left in place at…
The number of revision total knee arthroplasty (TKA) procedures performed is projected to increase at an annual rate of 19.3%.13 Femoral bone defects are uncommon in primary TKA but are…
Extensor mechanism disruption following total knee arthroplasty (TKA) is a devastating complication, with a prevalence of 0.17% to 2.5%.1,3 The patella tendon is involved more commonly (0.22%) than the quadriceps…
Total hip arthroplasty (THA) is successfully performed around the world for the treatment of arthritis, osteonecrosis, and femoral neck fracture, with predictably excellent results. The criteria for successful THA are…
