Introduction: Total hip arthroplasty (THA) for femoral neck fracture (FNF) cases is five times associated with the dislocation risk compared to THA for osteoarthritis. It is highlighted that a THA with dual mobility cup has lower rates of dislocation in elective surgery and revision procedures. However, there is a paucity in studies regarding this treatment area. The objective of this study was to evaluate the functional outcome of displaced FNF with dual mobility THA.
Materials and Methods: Two-year prospective study comprised of 25 patients with <10>55 years. Clinical and pain evaluation were done using Harris Hip score (HHS) and visual analogue scale (VAS) score. Paired T test was used to compare mean values and a P?0.05 was considered statistically significant.
Results: Most patients were aged 55-65 years and had comorbidities (84%). A significant change in pre- and post-operative HHS (81.86±11.37 vs. 90.67±7.86) as well as pre- and post-operative (1 and 6 month) VAS scores (6.40±0.82 vs. 1.56±0.65 and 6.40±0.82 vs 0.32±0.48; P<0 P=0.0261) P=0.0381)>
Conclusion: Current cement-less dual mobility THA is associated with a pain free mobile hip and durable acetabular fixation with an increased range of movements at the hip. Dual mobility cup may be considered a valuable option to prevent post-operative dislocation in elderly patients with FNF.
