Abstract
Background: Although total hip replacement (THR) remains one of the most successful procedures in modern orthopedic surgery, complications may occur. Dislocation is one of the major complications that may increase the hospital length of stay and even lead to a revision arthroplasty. Instability after total hip replacement can occur in 2% to 7% in primary cases and can reach up to 25% to 30% in revision cases and the majority of the dislocating events occur during the first three months after surgery.
Aim of the Work: To evaluate DM cups as a treatment option in selected group of patients at an elevated risk for instability after primary THA and will focus on dislocation and early implant survival following surgery.
Patients and Methods: In the period between September 2017 to March 2020 a prospective study was conducted involving 20 patients with high risk of dislocation underwent total hip replacement using dual mobility cup either as primary hip arthroplasty or after failed fixation of proximal femoral fractures. The last case was operated at February 2018. All cases were operated upon in Ain Shams University Hospitals and the follow up of the cases was 2 years.
Results: There were no case showed dislocation or intra-prosthetic dislocation till the last follow up.
Conclusion: In this study 1 case had complication. The complication was peri-prosthetic fracture after a fall while the prosthesis remain stable and was managed with reduction and fixation and the fracture healed with good final results and no intraoperative complication occurred with total complications rate 5%. This study showed that Dual mobility cups are efficient technique in preventing hip arthroplasty instability with good clinical results.
