Infected Shoulder Arthroplasty in Patients Younger than 60 Years: Results of a Multicenter Study.

Periprosthetic joint infection (PJI) after shoulder arthroplasty remains a significant complication. This study aimed to explore the epidemiology and risk factors of shoulder PJI in patients aged 60 and younger, analyze treatment options, and evaluate outcomes after 1-year follow-up. In this retrospective multicentric observational study, data from 1404 shoulders in patients under 60 who underwent primary shoulder arthroplasty were analyzed.

Midterm results of pyrocarbon interposition shoulder arthroplasty: good outcomes after posttraumatic osteonecrosis without malunion of the tuberosities.

Background: In vitro data demonstrate the potential benefits of the pyrocarbon as a bearing material against cartilage or bone. And pyrocarbon-free interposition arthroplasty has been used with positive outcomes for over 10 years for hand and wrist joint replacements. This study reports the midterm results of a Pyrocarbon Interposition Shoulder Arthroplasty (PISA) in primary and secondary glenohumeral osteoarthritis and in avascular osteonecrosis.

Reverse shoulder arthroplasty in rheumatoid arthritis: survival and outcomes.

Background: Despite its potential biomechanical advantages, reverse shoulder arthroplasty (RSA) is still considered to be particularly high risk in rheumatoid patients who are osteoporotic and immunodeficient. Our purpose was to report prosthesis survival, complications, and outcomes of RSA in patients with rheumatoid arthritis (RA) at minimum 5-year follow-up.

Methods: We conducted a retrospective multicenter study including 65 consecutive primary RSAs performed in 59 patients with RA between 1991 and 2010.

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.

Traumatic Isolated Myotendinous Rupture of the Teres Minor in a Young Athlete - A Unique Case Report.

Introduction: Functional role of teres minor (TM) is well known. To date, an isolated myotendinous rupture of the TM, without any lesion of the other cuff tendons, has never been reported in literature.

Case Report: The patient was a 22-year-old soccer player who has presented with a direct shoulder traumatism that is causing persistent pain and impairment.

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.

Iliotibial band friction syndrome: An original technique of digastric release of the iliotibial band from Gerdy's tubercle.

The various surgical techniques to treat iliotibial band friction syndrome consist in releasing the iliotibial band by means of plasties that partially interrupt its continuity or by release of the deep aspect. We describe an original technique of digastric distal iliotibial band release from Gerdy's tubercle. Via a 2 cm approach above Gerdy's tubercle, the iliotibial band is incised longitudinally and partially released from the tubercle.

Reverse shoulder arthroplasty for instability arthropathy.

Purpose: Osteoarthritis may be observed after surgery for instability and in the natural history of pathology. The primary objective was to analyze the late clinical and radiographic results of reverse shoulder arthroplasties (RSA) for patients who had instability arthropathy.

Methods: This is a retrospective cohort of 25 patients with a mean follow-up of 6.

Proper benefit of a three dimensional pre-operative planning software for glenoid component positioning in total shoulder arthroplasty.

Purpose: Glenoid loosening after total shoulder arthroplasty (TSA) is influenced by the position of the glenoid component. 3D planning software and patient-specific guides seem to improve positioning accuracy, but their respective individual application and role are yet to be defined. The aim of this study was to evaluate the accuracy of freehand implantation after 3D pre-operative planning and to compare its accuracy to that of a targeting guide.

Ten-Year Multicenter Clinical and MRI Evaluation of Isolated Supraspinatus Repairs.

Background: Early repair of isolated supraspinatus tears could prevent further deterioration of the rotator cuff; however, there is no consensus on the management of such tears because of a lack of long-term outcome studies. The purposes of this study were to report the 10-year outcomes of isolated supraspinatus repairs and to investigate the factors that favor healing and recovery.

Methods: We retrieved the records of all 511 patients who, in 2003, underwent repair of full-thickness isolated supraspinatus tears, performed by 15 surgeons at 15 centers.

Pyrocarbon interposition shoulder arthroplasty: preliminary results from a prospective multicenter study at 2 years of follow-up.

Background: The concept of free interposition arthroplasty proved successful for small joints of the hand, wrist, and foot, particularly after the use of implants coated with pyrocarbon, which enhanced their tribologic and elastic properties. The present study reports preliminary outcomes of a pyrocarbon-coated interposition shoulder arthroplasty (PISA) implant.

Methods: This was a prospective study of 67 consecutive patients who underwent shoulder PISA at 9 centers.

Is radiographic measurement of acromiohumeral distance on anteroposterior view after reverse shoulder arthroplasty reliable?

Background: Reverse shoulder arthroplasty leads to arm lengthening. Different techniques have been described to determine postoperative lengthening. The purpose of this study was to evaluate the reliability of the acromiohumeral distance (AHD) in determining arm lengthening after reverse shoulder arthroplasty.

Surgical management of the infected reversed shoulder arthroplasty: a French multicenter study of reoperation in 32 patients.

Background: In a retrospective multicenter study, we evaluated the efficiency and outcomes of the different therapeutic options for infection after reversed shoulder arthroplasty.

Methods: Thirty-two patients were reoperated on for infection after reversed shoulder arthroplasty between 1996 and 2011. The mean age was 71 (55-83) years.

Aseptic glenoid loosening or failure in total shoulder arthroplasty: revision with glenoid reimplantation.

Hypothesis And Background: Reimplantation of a new glenoid component for symptomatic glenoid failure after total shoulder arthroplasty (TSA) is a well-established surgical strategy. In case of aseptic glenoid loosening or failure, revision of TSA by reimplantation of a cemented glenoid implant would be a reliable therapeutic option.

Materials And Methods: This retrospective multicenter study included 42 TSAs with symptomatic failed glenoids revised by reimplantation of an all-polyethylene (PE), cemented glenoid component.

Patterns of loosening of polyethylene keeled glenoid components after shoulder arthroplasty for primary osteoarthritis: results of a multicenter study with more than five years of follow-up.

Background: The aim of this study was to radiographically analyze the long-term glenoid migration patterns following total shoulder arthroplasty to better understand the factors responsible for loosening.

Methods: Complete radiographic follow-up of more than five years was available for 518 total shoulder arthroplasties performed for primary glenohumeral osteoarthritis with use of an anatomically designed prosthesis with a cemented, all-polyethylene, keeled glenoid component. Radiographs were assessed for humeral head subluxation, periprosthetic radiolucent lines, and shifting of the position of the glenoid component.

Surgical technique: the anterosuperior approach for reverse shoulder arthroplasty.

Background: The anterosuperior approach used for reverse shoulder arthroplasty is an intermediate between the transacromial approach originally proposed by Paul Grammont and the anterosuperior approach described by D. B. Mackenzie for shoulder arthroplasty.

Reverse prostheses in arthropathies with cuff tear: are survivorship and function maintained over time?

Background: The use of reverse shoulder arthroplasty has considerably increased since first introduced in 1985. Despite demonstrating early improvement of function and pain, there is limited information regarding the durability and longer-term outcomes of this prosthesis.

Questions/purposes: We determined complication rates, functional scores over time, survivorship, and whether radiographs would develop signs of loosening.

What do standard radiography and clinical examination tell about the shoulder with cuff tear arthropathy?

Background: This study evaluates the preoperative conventional anteroposterior radiography and clinical testing in non-operated patients with cuff tear arthropathy. It analyses the radiological findings in relation to the status of the rotator cuff and clinical status as also the clinical testing in relation to the rotator cuff quality. The aim of the study is to define the usefulness of radiography and clinical examination in cuff tear arthropathy.

Acromial insufficiency in reverse shoulder arthroplasties.

Hypothesis: Reverse shoulder prostheses depend on deltoid function. An injury to the acromion, either fracture or meso-acromion, or deltoid injury, may affect the outcomes of patients after receiving a reverse shoulder prosthesis.

Methods: Four-hundred and fifty-seven consecutive reverse shoulder prostheses were implanted between January 1992 and June 2003 by one of seven surgeons in five separate centers.

Scapular notching in reverse shoulder arthroplasty.

The causes and consequences of scapular notching after reverse shoulder arthroplasty (RSA) were investigated in 326 consecutive patients (337 shoulders) undergoing RSA between 1991 and 2003. Patients underwent 269 (80%) primary RSAs and 68 revisions of unconstrained shoulder prosthesis. At last follow-up (average, 47 months; range, 24-120 months) 62% had scapular notching.

Glenosphere disengagement: a potentially serious default in reverse shoulder surgery.

Unlabelled: Implant failure is a serious complication in reverse shoulder arthroplasty. We determined the incidence of glenosphere disengagement in a cohort of 479 reverse shoulder prostheses (468 Delta III [DePuy International Ltd, Leeds, UK], 11 Aequalis [Tornier, Grenoble, France]). We also determined whether disengagement adversely affected clinical outcomes.
