Non-invasive navigation in total knee arthroplasty : a validation study.

The purpose of this study was to evaluate intraope- rative alignment during total knee arthroplasty using a handheld navigation system, iAssist, in comparison with conventional optical surgical navigation. Sixty-two consecutive patients were enrolled in this prospective study. iAssist was used to determine implant component positioning.

Locking plates versus retrograde intramedullary nails in the treatment of periprosthetic supracondylar knee fractures. A retrospective multicenter comparative study.

Introduction: Biomechanical studies demonstrated the superiority of retrograde supracondylar intramedullary nails (RIN) against locking plates (LP) for the treatment of periprosthetic supracondylar femoral fractures (PSFs); however, clinical results are still conflicting. This study aimed to compare LP and RIN, as well as, cemented and uncemented nails in the treatment of PSFs regarding fracture healing, complications and functional results.

Materials And Methods: A retrospective multicenter analysis of 60 PSFs classified as Rorabeck type I or II was performed.

[74-year-old man with a complex acromio-clavicular disjunction].

Acromioclavicular dislocation is a frequent pathology commonly encountered in traumatology. Therefore, its management is generally standardized, guided by clinical and radiological evaluation. This can range from conservative treatment by limb immobilization and functional rehabilitation, to surgical treatment by using minimally invasive techniques.

[Total hip arthroplasty : history and perspective of an iconic surgerical intervention].

With nearly 2 million implants placed annually, total hip arthroplasty is one of the most frequently performed surgerical procedure. A historical review of this intervention reminds us of the times when surgery was done by barber, before the first attempts of interposition arthroplasty. It is only in 1970 that Sir John Charnley lay the foundations of modern arthroplasty.

Management of greater trochanteric pain syndrome : a systematic review.

Greater trochanteric pain syndrome is characterized by pain at or around the greater trochanter. Numerous management modalities have been proposed, with varying success. Cochrane and Pubmed database have been searched from 1990 for studies focusing on the management of this syndrome.
