Introduction: Glenohumeral arthritis with a massive rotator cuff tear is a devastating condition that seriously compromises the comfort and function of the shoulder. Cuff tear arthropathy presents a unique surgical challenge and many arthroplasty options were used for its treatment. The purpose of this study was to evaluate the clinical and radiological results of Copeland cementless
Avascular necrosis (AVN) of the humeral head is an extremely disabling condition (Gerber et al, JSES 1998. 7(6):586–90). The results of stemmed arthroplasty for this condition are good, with Hattrup and Cofield reporting 79% subjective improvement at nine years (JSES 2000;9:177–82). This study reports the outcomes of

The classic Hill-Sachs lesion is a compression or impression fracture of the humeral head in occurrence with anterior glenohumeral instability. The true incidence is unknown but clearly increases with recurrent instability episodes. Recent peer-reviewed literature has highlighted the importance of addressing “significant” humeral and glenoid bone defects in the management of glenohumeral instability. Quantification of the “significance” of a Hill-Sachs lesion with regard to location, size, and depth in relation to the glenoid has helped guide indications for surgical management. Options for managing Hill-Sachs lesions include both humeral-sided techniques (soft tissue, bone, and/or prosthetic techniques) and also glenoid-sided techniques (bone transfers to increase glenoid width). The majority of significant acute or chronic Hill-Sachs lesions can be effectively managed without prosthetic replacement. Is a prosthetic

Total hip arthroplasty (THA) is among the most successful interventions in all of medicine and has recently been termed “The Operation of the Century”. Charnley originally stated that “Objectives must be reasonable. Neither surgeons nor engineers will ever make an artificial hip joint that will last 30 years and at some time in this period enable the patient to play football.” and he defined an appropriate patient as generally being over 65 years of age. Hip rating scales developed during this time were consistent with this approach and only required relief of pain and return to normal activities of daily living to achieve a perfect score. Since this time, however, hip arthroplasty has been applied to high numbers of younger, more active individuals and patient expectations have increased. One recent study showed that in spite of a good hip score, only 43% of patients had all of their expectations completely fulfilled following THA. The current generation metal-metal hip

Purpose: The presence of metal ions in the blood of patients with a metal-on-metal (MM) bearing points to the importance of understanding the long-term effects of these ions. Metal ions have the potential to induce the production of reactive oxygen species (ROS), making them prime suspects for inducing molecular damage in circulating cells. The aim of this study was to analyze the levels of oxidative stress markers in the plasma of patients with hip

Hill-Sachs and reverse Hill-Sachs lesions come in different shapes and sizes, and their effect on “glenoid track” can vary. Small Hill-Sachs lesions that do not engage can be successfully treated with a Bankart repair alone done arthroscopically or open. Moderate, engaging, Hill-Sachs lesions can be treated either with the addition of remplissage to an arthroscopic Bankart or by adding the triple blocking effect of the Bristow-Latarjet procedure.
