Reversed assembly of total hip arthroplasty components: a surgical tip to facilitate implant reduction during minimally invasive surgery.

Total hip arthroplasty (THA) using minimally invasive surgery (MIS) can result in soft tissue damage during the trial reduction and actual implantation. We present a surgical technique that reduces soft tissue trauma and facilitates implant reduction while protecting the prosthetic head from scratching during MIS THA. Primary THA using MIS was performed in 16 hips through a transgluteul direct lateral approach. Average follow-up was 54 months (range 52-58 months). At latest follow-up there was no evidence for component dissociation or loosening in any of the patients. Reverse assembly of THA components is a viable option, which may facilitate MIS THA and decrease soft tissue trauma.
