Total hip arthroplasty using TRI-LOCK® DePuy bone preservation femoral stem: our experience.

PURPOSE: In this study we report our 3-years experience (from January 2010 to December 2013) of 101 total hip arthroplasties using Tri-Lock® DePuy bone preservation femoral stem, all performed in our clinic. METHODS: 101 patients (F54-M47; median age around 69 yrs, range 42-84 yrs). 51 arthroplasties were implanted on the right side whereas 50 on the left side. The average follow-up was 27,3 months. All the arthroplasties were coupled with Pinnacle® polyethylene acetabular cup system; 98 prostheses were implanted cementless whereas cement was used in 3 cases. RESULTS: The Tri-Lock® femoral stem allows both soft tissues and bone stock preservation, leading to greater trochanter maintenance, less spongy bone removal and distal cavity bone tissue conservation. In our experience, we were able to implant the Tri-Lock® femoral stem even in osteoporotic and overweight patients using Gription® porous coating. This allowed for commencing an intensive rehabilitation program with stable load from the following day, without observing any early complications or loosening. CONCLUSIONS: According to us, this device is solid and safe, providing remarkable sparing of both soft tissues and bone stock.

Metatarsophalangeal joint arthroplasty with implantation of Osteomed Interflex IPG system: our experience.

The Osteomed Interflex IPJ system is a stemmed flexible implant specifically designed for replacement of metatarso-phalangeal joints of the lesser toes. The indication for use is a semi-rigid or rigid hammertoe deformity, impaired function and stability, metatarsal pain. The purpose of the study is the result of 45 implants, in 29 patients (27 women and 2 men). The average of the patients at the time of the operations was 65 years. The follow-up is 30 months. In our experiences this surgical replacement is a good solutions in selectionated cases of metatarso-phalangeal deformity.
