“…Stem loosening with 12.2% and femoral shaft fractures with 14.3% were observed relatively less contributing to all dislocations caused by femoral component defects. An uncommon case was examined with complete femoral stem migration from the femoral shaft due to femoral component loosening [22]. In order to reduce the stresses on the stem area after prosthetic hip implantation, several studies have been reported on the stress analysis of femoral stems [23,24].…”

Major contributing parameters to hip implant dislocation include preoperative, intra-operative and post-operative factors. Implant geometry are design as well as non-design related. Femoral and acetabular component design features causing dislocation and/or resisting it are elucidated. Twelve implants were designed during this investigation were analyzed for dislocation resistance. A safe zone, establishes combinations of implant dimensions, was analyzed for all the 12 implants where implants were dislocation resistant. Head diameters between 26 mm to 32 mm, neck diameters closer to 14 mm, and neck angle between 25 to 35º were examined to be the safest ranges for hip implant designs.

Displacement of a cemented femoral implant. A complication of manipulation of a dislocated total hip replacement

Dislocation is a common complication of total hip replacement, which has been quoted in the literature as having an incidence of 1–4%. This is commonly treated with closed reduction. The authors present a case report of displacement of a cemented smooth-polished tapered femoral stem, which occurred while attempting closed reduction of a dislocated hybrid total hip replacement. The patient required full revision arthroplasty.

Complete Displacement of the Femoral Stem During Dislocation of a THR

Abstract: We report an unusual complication of late dislocation of a total hip replacement. The femoral stem had completely migrated from the shaft. The insertion of a new long-stem prosthesis was successful.
