  • Title: Tension-free closure with capsular lengthening in mini posterior total hip replacement.
    Author: Santori N.
    Journal: Hip Int; 2018 Nov; 28(2_suppl):3-9. PubMed ID: 30755121.
    Abstract:
    PURPOSE:: Choice of the best mini invasive surgical approach for total hip replacement remains a controversial topic. The posterior approach is traditionally associated with a higher dislocation rate and the obligation of postoperative restrictions. Soft tissue repair reduces the risk of dislocation yet, posterior closure it is often challenging because of capsular and external rotator contractures. In this article, an original procedure of capsular lengthening and tension-free closure is described and the results of a retrospective single surgeon series of minimally invasive posterior total hip replacement (THR) with capsular repair are presented. METHODS:: A total of 925 mini posterior total hip replacements performed between 2009 and 2015 were retrospectively reviewed. 2 original types of capsulorrhaphy to decrease tension of the repaired tissues were employed. Absence of posterior envelope stretch during flexion and internal rotation was confirmed intraoperatively with a dynamic test. No postoperative restrictions were used. RESULTS:: Capsular lengthening with 1 of the described techniques was required in over 50% of cases for a tension-free closure. 3 patients dislocated in the 867 reviewed procedures (0.35%), 1 requiring revision for instability (0.11%). CONCLUSIONS:: This soft tissue repair technique after mini posterior approach THR is technically easy, provides a tension-free closure and a low dislocation rate.
