Proximal humeral bony adaptations with a short uncemented stem for shoulder arthroplasty: a quantitative analysis.

Background: Short uncemented stems have recently been proposed as an alternative to classic long stems for shoulder arthroplasty. The early results are promising, but bony adaptations of the proximal humerus have been reported. The aim of this study was to quantify these phenomena using the Ascend Flex stem and to determine the risk factors.

Anteversion and length of the femoral tunnel in ACL reconstruction: in-vivo comparison between rigid and flexible instrumentation.

Background: Due to it being tangential to the distal femoral axis, the anteromedial portal presents significant risk of causing iatrogenic damage, and of producing tunnels that are too short for optimal osseointegration. Flexible reamers were developed to eliminate the need for knee hyperflexion and offer better-controlled orientation of the femoral tunnel. We aimed to compare the anteversion and length of femoral tunnels drilled using flexible reamers to those drilled using rigid reamers.

Antegrade nailing evolution for proximal humeral fractures, the Telegraph IV(®): a study of 67 patients.

Introduction: There are multiple surgical treatment methods for proximal humerus fractures (PHF), but rarely do they provide satisfactory results. The objective of this study was to assess radioclinical outcomes and complications in patients treated using a modern intramedullary nailing system the Telegraph I(®).

Materials And Methods: This is an observational multicenter study cohort conducted between March 2008 and December 2009 on 105 patients admitted with a diagnosis of PHF and operated on two trauma I centers.
