Results of single stage exchange arthroplasty with retention of well fixed cement-less femoral component in management of infected total hip arthroplasty.

Aim: To investigate success of one stage exchange with retention of fixed acetabular cup.

Methods: Fifteen patients treated by single stage acetabular component exchange with retention of well-fixed femoral component in infected total hip arthroplasty (THA) were retrospectively reviewed. Inclusion criteria were patients with painful chronic infected total hip.

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.
