“…The offset of the neck as well as the head can be altered in modular bipolar prostheses allowing easier dislocation, limb length correction and placing of acetabular socket while revision to total hip arthroplasty. Hodgkinson et al showed in 82.6% cases the Modular bipolar prostheses behaved as a bipolar with good results [46]. Gaine et al had a 70 to 80% intraprosthetic motion in flexion extension in weight bearing following modular bipolar prostheses for fracture neck of femur [47] .…”

Background: The long term follow up results of hemiarthroplasty (unipolar or bipolar) for fracture neck of femur are not promising due to high incidence revision. The objective of this study is to provide useful information on the mode of failure of hemiarthroplasty in those who required revision, and the magnitude and complications of conversion total hip arthroplasty. Materials and Methods: Twenty two cases, 14 women and 8 men, average age 61 years (range 42-75 years) of failed hemiarthroplasty were converted to total hip replacement between June 2011 and January 2015. Thigh pain was the main presenting complaints in the majority of the patients (10 out of 22).Two patients had infection and were operated with staged procedure. All acetabular and the majority (86.5%) of femoral components used in our series were uncemented. Results: After an average follow-up of 41 months (Range, 13-86 months) Harris hip scores improved from 36.4 (range 28-42) preoperatively to 84.7 (range 69 to 98) postoperatively. We had 19 patients with no hip pain and 3 patients with slight pain. Also, at the last follow up 19 (86.3%) patients were community ambulators without support while 3 (13.6%) needed minimal support of cane. Range of motion improved significantly and was essentially normal in all. Postoperative complications included persistent groin pain in 2 patients, superficial infection in one, and sciatic nerve neuropathy in one patient which recovered completely in one year. In the last follow-up of conversion total hip prosthesis, there was no radiolucency in either femoral or acetabula components. Conclusion: Total hip arthroplasty can be reliable in eliminating groin pain following failed hemiarthroplasty and modular bipolar hemiarthroplasty is recommended in middle a ged patients with fracture neck of femur and in elderly patients with active life style with femoral neck fractures, primary total hip arthroplasty has better results.

“…Early radiological studies of interprosthetic motion in bipolar hemiarthroplasties showed little or no movement between the stem and the head over time when analysing passive motion of the hip without weightbearing. [70][71][72][73][74] Later studies analysing the interprosthetic movement during weight-bearing have, however, showed a preserved movement of the inner joint during the stance phase of gait. 68;75;76 Despite the seemingly obvious differences in favour of bipolar prostheses reported in separate patient series, the advantages of the bipolar design has yet to be proven in randomised trials.…”

We report 11 cases of interprosthetic dislocation of the Charnley/Hastings hemiarthroplasty in a retrospective study of 350 consecutive patients treated for an acute femoral neck fracture. We found a total of 14 dislocations (4.0%), 11 were interprosthetic. The median age of the 350 patients was 79 (36-99) years and the median age of the 11 patients with an interprosthetic dislocation was 85 years (82-94). The median time from surgery to radiologically acknowledged dislocation was 18 (4-64) days. These interprosthetic dislocations may be caused by either an assembly mistake perioperatively, by maximum angulation and impingement between the components, or by trauma.
