Capsulorrhaphy using suture anchors in open reduction of developmental dislocation of hip: technical note

Abstract

We describe a new technique of using titanium alloy anchors to perform internally rotating capsulorrhaphy during open reduction and stabilization procedure and obliteration of pseudoacetabulum when one exists. We routinely use anterior approach via bikini incision (modified Smith-Peterson approach) to perform open reduction and internally rotating capsulorrhaphy. We describe the technique of using barbed titanium alloy anchors preloaded with nonabsorbable sutures and two needles, to accomplish a secure and easy capsulorrhaphy, in selected cases. We have used this technique in 21 hips, since 2008. None of the hips redislocated and hip movements were symmetrical in most cases at 6 months after surgery. One anchor appeared 5 mm away from the pubic ramus on first radiograph at 6 months without any adverse effect on the outcome. It did not migrate any further on follow up radiographs. MRI scan of hip obtained for another purpose confirmed that it was not intra-articular. Capsulorrhaphy using barbed titanium anchors with nonabsorbable ethibond sutures is an effective, safe and technically easy alternative to standard capsulorrhaphy using needles and sutures in selected cases.
