Depuy shoulder

S Gruber, C Schoch, M Geyer
BACKGROUND: Reverse shoulder arthroplasty (RSA) has become a frequently used and established treatment for patients with cuff tear arthropathy, increasingly also for patients with fracture sequelae (FS), failed rotator cuff reconstruction and omarthrosis with cuff insufficiency. Since 2007 new generation prostheses, for example Delta Xtend (Depuy, Warsaw, USA), have been used, but few mid-term results have been published. OBJECTIVES: The aim of this study is to report on the outcome after RSA after a mean follow-up of 68 months (range 63-75), to verify the already published, encouraging early results and to learn about the function and pain situation after RSA in the mid-term period...

BACKGROUND: A prerequisite for a satisfying functional result in the treatment of comminuted fractures of the proximal humerus with hemiarthroplasty is anatomical reduction, fixation and healing of the tuberculi around the prosthetic neck in order to restore normal function of the rotator cuff. PURPOSE: This was a retrospective study to examine the outcome after hemiarthroplasty using a prosthetic stem designed to optimise re-attachment and healing of the tuberculi (Aequalis; Tornier and Global Fx, DePuy)...

INTRODUCTION: Paul Grammont's hemispherical gleno sphere concept medializes the center of rotation (CoR) to the glenoid face to increase deltoid abductor moment arms and improve muscle efficiency. Reducing glenosphere thickness to less than half its spherical radius further medializes the CoR and offers the potential for even greater improvements in efficiency. To that end, this study quantifies deltoid abducttor moment arms for six different rTSA prostheses during scapular abduction from 0° to 140°...

Shoulder instability can be a challenging condition to treat when it becomes refractory to soft-tissue procedures or when bone loss exceeds 25% to 27% of the glenoid. The Bristow-Latarjet procedure has been developed and popularized to deal with these concerns. Traditionally, the procedure has been performed as an open approach; however, this has been recently supplanted by novel arthroscopic techniques. We present a technique for the procedure performed with the patient in a semi-lateral decubitus position that assists with optimal graft placement on the native glenoid...

BACKGROUND: Minimally invasive spine (MIS) techniques have been available for many years, but their application has been largely limited to degenerative spine diseases. There are few reports in the literature of using MIS techniques for removal of neoplasms. We report our experience using a modified MIS technique for removal of an occipital-cervical junction (OCJ) schwannoma with attention to technical aspects of this approach. CASE DESCRIPTION: A 64-year-old male presented with several months of neck pain radiating to the shoulder with bilateral hand numbness...

PURPOSE: Cranial migration of shoulder hemiarthroplasties due to rotator cuff insufficiency typically requires conversion into a reverse total shoulder arthroplasty. This study was conducted to analyze differences between the height and offset of six implants designed to enable conversion of a hemiarthroplasty into a reverse system. METHODS: Anteroposterior radiographs of 40 shoulders were taken. An image analyzing software was used to simulate the implantation of the hemiprostheses...

INTRODUCTION: Total shoulder resurfacing (TSR) provides a reliable solution for the treatment of glenohumeral arthritis. It confers a number of advantages over traditional joint replacement with stemmed humeral components, in terms of bone preservation and improved joint kinematics. This study aimed to determine if humeral reaming instruments produce a thermal insult to subchondral bone during TSR. PATIENTS AND METHODS: This was tested in vivo on 13 patients (8 with rheumatoid arthritis and 5 with osteoarthritis) with a single reaming system and in vitro with three different humeral reaming systems on saw bone models...

We describe our experience with a new system of patient-specific template called Personal Fit(®), which is unique in shoulder surgery and used in combination with Duocentric(®) prosthesis. The reverse prosthesis's concept is the invention of Paul Grammont, developed with Grammont's team of Dijon University as from 1981, which led to the first reversed total shoulder prosthesis called Trumpet in 1985. The Duocentric(®) prosthesis developed in 2001 is the third-generation prosthesis, coming from the Trumpet and the second-generation prosthesis Delta(®) (DePuy)...

BACKGROUND: Glenoid component failure is the most common complication of total shoulder arthroplasty. It can be correlated with failure of the component itself to resist wear and deformation, failure of fixation or failure of the glenoid bone. Anchor Peg Glenoid component (Depuy®) seems to have a higher bone fixation in biomechanical canine model: it is a all-polyethylene, concave component with one circumferentially fluted, central, interference-fit peg and three small cemented peripheral pegs...
