“…[2]. Multiple treatment options for acetabular reconstruction had been described, including the application of bulk autograft or allograft alone or in combination with prosthesis, ranging from jumbo cup construct, mechanical and biologic cup-cage construct, trabecular metal augment and shell, dual mobility cup, and some others [1,3]. Trabecular metal and dual mobility cup were widely used to construct complex acetabular defects in revision surgery [1,3].…”

“…Because of good to excellent prognosis, primary total hip arthroplasty (THA) is an effective management of hip degenerative pathologies [1]. Failure rate requiring reoperation after THA is higher (8.9%-24.1%) at 5-year follow-up [1]. With the younger tendency and rising life expectancy of patients, the number of revision surgery following THA is expected to increase in the near future [2].…”

“…However, acetabular revision for severe bone defects is still a challenging surgery because of the high incidence of complications [4,5]. The main complication is dislocation after revision hip arthroplasty [3], and it is more common in revision hip arthroplasty than primary THA [1]. Restoration of the native hip center of rotation (COR) is crucial in primary THA and revision hip arthroplasty [6].…”

Background: Acetabular revision is often difficult to manage because of severe bone loss, especially for Paprosky type Ⅲ defects. Our present study aimed to assess the strategy of double-trabecular metal cups in acetabular revision.Methods: Fifteen patients (15 hips) underwent acetabular revision using double-cup technique alone or in combination with impacting bone grafting between January 2008 and May 2015. Preoperative and the latest follow-up clinical and radiographic scores were recorded and compared. Results:No patients were lost to follow up, and no patients underwent re-revision for loosening or any other reasons at the mean follow-up duration of 66 (range 55-105) months. We discovered 3 patients (3/15) with the early dislocation within the first year after the surgery and 2 patients (2/15) with delayed wound healing. The comparison between preoperative and the latest follow-up results showed the records of modified Harris Hip Score, University of California, Los Angeles activity score, Short Form 36, limb-length discrepancy and hip center of rotation were significantly improved. Conclusions:The application of double-cup technique alone or in combination with impacting bone grafting is an effective and reliable treatment option for Paprosky type Ⅲ acetabular defects without pelvic discontinuity.

Introduction Evolving surgical techniques in total hip arthroplasty (THA) have sought to make the surgical procedures safer. This requires having highly reproducible incision landmarks and simplifying the procedures. The postero-posterolateral approach, a very posterior incision in the hip, meets those requirements. However, this has not helped to reduce the postoperative dislocation rate. The aim of this study was to assess the relevance of combining the postero-posterolateral approach and next-generation dual mobility cups (DMC) in terms of dislocation risk. Materials and methods One hundred and fifty-eight THA were performed consecutively using the postero-posterolateral approach on 150 patients, by a single surgeon, over a 49-month period (November 2010 to December 2014). All acetabular implants were impacted. Results Average length of the incision was 7 cm (6 to 9 cm). Mean duration of the surgical procedure was 75 minutes (40 to 100). Mean blood loss was estimated at 210 cc (25 to 410 cc). All patients could walk with assistance the day before transferring to a rehabilitation centre. There was one posterior dislocation (0.63%), without recurrence. Conclusion The straightforwardness and reproducibility of the anatomical landmarks used for the postero-posterolateral approach, added to the stability of the dual mobility cup, result in a safe combination in the therapeutic THA arsenal.
