Outcomes of Acetabular Reconstructions for the Management of Chronic Pelvic Discontinuity: A Systematic Review

et al. 2020

J Orthop Surg Res

Background: The acetabular distraction technique demonstrates encouraging radiographic and clinical outcomes in treating chronic pelvic discontinuity. The aim of this study is to describe a modified distraction technique and to show our results. Methods: This study identified 12 cases of chronic pelvic discontinuity undergoing primary or revision total hip arthroplasty (THA) with the technique of reverse reaming distraction between July 2015 and November 2018. All 12 patients had a minimum follow-up of 12 months. Radiographs were reviewed to inspect for component loosening. Clinical assessment included the Harris hip score (HHS) and an ambulatory scoring system. Results: At the time of final follow-up, no patient was revised. One patient had up to 1 cm migration of the cup in a horizontal or vertical direction and more than 20°change in the abduction angle but was asymptomatic. In the remaining 11 patients, no migration of the component was detected. Both the HHS and ambulatory score showed improvement in all patients. There were no perioperative complications. No postoperative dislocation occurred. Conclusions: Reverse reaming distraction is a feasible technique in treatment of chronic pelvic discontinuity, with encouraging results at early term. However, ongoing follow-up is required to determine the long-term prognosis in patients receiving this technique.

“…The most common reason for reoperation after cupcage or CTAC reconstruction was dislocation [18]. Especially in the use of CTAC, the relatively bigger construct provided more access to prosthetic impingement, injury of the superior gluteal nerve, and soft tissue dissection.…”

“…Data showed that both CTAC and acetabular distraction techniques had a less than 5% all-cause revision rate at mean midterm follow-up. Being the most commonly used method, cup-cage construct had an 8.1% revision rate for the acetabular component [18]. Thus can be seen, our results of the distraction technique are encouraging.…”

Introduction The acetabular distraction technique demonstrates encouraging radiographic and clinical outcomes in treating chronic pelvic discontinuity. The aim of this study is to describe a modified distraction technique and to show our results. Methods This study identified 12 cases of chronic pelvic discontinuity undergoing primary or revision total hip arthroplasty (THA) with the technique of reverse reaming distraction between July 2015 and November 2018. All 12 patients had a minimum followup of 12 months. Radiographs were reviewed to inspect for component loosening. Clinical assessment included the Harris hip score (HHS) and an ambulatory scoring system. Results At the time of final follow-up, no patient was revised. One patient had up to 1 cm migration of the cup in a horizontal or vertical direction and more than 20° change in the abduction angle but was asymptomatic. In the remaining 11 patients, no migration of the component was detected. Both the HHS and ambulatory score showed improvement in all patients. There were no perioperative complications. No postoperative dislocation occured. Conclusions Reverse reaming distraction is a feasible technique in treatment of chronic pelvic discontinuity. Sometimes it can work with the aid of augment or cup-cage construct. When both the superior and inferior portions of the pelvis achieve osteointegration into the porous metal cup, a long-term durability can be expected.
