: Thumb carpometacarpal joint replacement is associated with high rates of loosening and failure. We present our results for an uncemented ceramic-ceramic total joint prosthesis with a reverse ball-and-socket design and bioactive coating. Between 2008 and 2012, 29 prostheses were inserted into 28 patients (mean age 63 years) with advanced osteoarthritis. After a mean period of 33 months (range 9-62), 26 patients (27 implants) were available for follow-up. Six months postoperatively, 50% of the patients had radiological evidence of early loosening...

OBJECTIVE Global brachial plexus lesions with multiple root avulsions are among the most severe nerve injuries, leading to lifelong disability. Fortunately, in most cases primary and secondary reconstructions provide a stable shoulder and restore sufficient arm function. Restoration of biological hand function, however, remains a reconstructive goal that is difficult to reach. The recently introduced concept of bionic reconstruction overcomes biological limitations of classic reconstructive surgery to restore hand function by combining selective nerve and muscle transfers with elective amputation of the functionless hand and its replacement with a prosthetic device...

REVIEW
C Hulet, G Rochcongar, C Court
Under the new categorization introduced by the Health Authorities, ambulatory surgery (AS) in France now accounts for 50% of procedures, taking all surgical specialties together. The replacement of full hospital admission by AS is now well established and recognized. Health-care centers have learned, in coordination with the medico-surgical and paramedical teams, how to set up AS units and the corresponding clinical pathways. There is no single model handed down from above. The authorities have encouraged these developments, partly by regulations but also by means of financial incentives...

The extracellular matrix (ECM) provides core support which is essential for the cell and tissue architectural development. The role of ECM in many pathological conditions has been well established and ECM-related abnormalities leading to serious consequences have been identified. Though much has been explored in regards to the role of ECM in soft tissue associated pathologies, very little is known about its role in inflammatory disorders in tendon. In this study, we performed microRNA (miRNA) expression analysis in the long head of the human shoulder biceps tendon to identify key genes whose expression was altered during inflammation in patients with glenohumeral arthritis...

Background: An increasing number of physically active patients not only need to know if they will basically be able to engage in sports after undergoing arthroplasty. They also would like to know whether or not they will be able to resume their preoperative activity levels. This article aims to provide an overview of recent data regarding the following questions on hip, knee and shoulder arthroplasty: (1) What is the impact of physical activity on an endoprosthesis? (2) What level of sports can be achieved after an arthroplasty procedure? (3) What types of sport are recommended for patients with an endoprosthesis? Methods: PubMed-based review of the literature...

BACKGROUND: Geriatric traumatology is increasing in importance due to the demographic transition. In cases of fractures close to large joints it is questionable whether primary joint replacement is advantageous compared to joint-preserving internal fixation. OBJECTIVE: The aim of this study was to describe the importance of prosthetic joint replacement in the treatment of geriatric patients suffering from frequent periarticular fractures in comparison to osteosynthetic joint reconstruction and conservative methods...

The authors report their experience in the management of a 53-year-old woman with rheumatoid arthritis who presented with bilateral asynchronous traumatic periprosthetic fractures of the humerus after bilateral elbow replacements. One side was treated with a long-stem revision and internal fixation with bone graft, while the other side was treated with a long-stem distal humeral replacement. She sustained pathological periprosthetic fractures on top of the long-stemmed implants. Total humeral endoprosthesis replacements were performed bilaterally as salvage procedures to provide a stable platform for her elbow and hand function...

BACKGROUND: Shoulder pain and loss of function are directly associated with obesity. QUESTIONS/PURPOSES: We hypothesized that significant interactions would exist between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RSA) and obesity status on functional and quality of life (QOL) outcomes over the long term. Clinical and QOL outcomes (American Shoulder and Elbow Surgeons Evaluation form, Shoulder Pain and Disability Index, University of California at Los Angeles Shoulder Rating scale, Medical Outcomes Short Form 12 (SF-12), range of motion (ROM), and strength) were longitudinally compared in patients with low and high body mass index (BMI) after a TSA or a RSA...

Cutaneous polyarteritis nodosa (CPAN) is a chronic, indolent, single organ arteritis that generally presents with lower extremity nodules and/or livedo racemosa, accompanied by malaise and arthralgias. CPAN is often triggered by infection, commonly Group A streptococcal species, and is considered an autoimmune reaction. Scarring from surgery and obliterative lymphangiitis from bacterial cellulitis are the causes of lymphedema. Lymphedematous skin is predisposed to autoimmune disorders. Herein we report a 53-year-old woman who developed CPAN restricted to a localized area of the right upper arm-shoulder that had undergone multiple surgeries, complicated by episodes of Streptococcus viridans cellulitis...

INTRODUCTION: The most frequent indications for anatomic shoulder replacement are glenohumeral osteoarthritis and fractures of the humeral head. If anatomic shoulder prostheses fail, reverse total shoulder arthroplasty is often the only remaining treatment option. This study evaluates the influence of indications for primary shoulder arthroplasty on the clinical outcome after conversion to reverse total shoulder arthroplasty. MATERIALS AND METHODS: From 2010 to 2012, 44 failed shoulder arthroplasties were converted to reverse total shoulder arthroplasty...

BACKGROUND: Stemless humeral head replacement represents a young generation of shoulder arthroplasty. This study evaluated the differences of this new stemless design compared with the fourth-generation standard stemmed design. METHODS: Total shoulder arthroplasty was performed in 20 patients with a stemless shoulder prosthesis (group 1) and in 20 patients with a standard stem humeral head replacement (group 2). Twenty-nine patients were examined clinically and radiographically at a minimum follow-up of 2 years and a minimum follow-up of 5 years...

BACKGROUND: Many studies have noted an increase in the number of recognized cases of invasive infections due to Propionibacterium acnes, especially after shoulder replacement surgery. The increase in the number of recognized cases of P. acnes, a nonspore-forming, anaerobic, Gram-positive organism, appears due to both an increase in the number of shoulder operations being performed and more specimens being sent for anaerobic cultures. Nevertheless, the optimal surgical and antibiotic management of P...

INTRODUCTION: Patient-specific implants and instruments (PSI) have been used in both knee and shoulder replacements due to the perceived benefits of improved surgical accuracy and efficiency. The proposed benefits of using a PSI in total hip arthroplasty (THA) are numerous and include reduction of operative time and improved mechanical and anatomical alignment leading to increased implant longevity, increased stability, and clinical outcomes. We describe a novel patient-specific instrumentation and a surgical method that may improve directed resection of acetabular bone and accurate cup placement during THA...

BACKGROUND: Compared with total shoulder arthroplasty (TSA), total shoulder surface replacement (TSSR) may offer the advantage of preservation of bone stock and shorter surgical time, possibly at the expense of glenoid component positioning and increasing lateral glenohumeral offset. We hypothesized that in patients treated for osteoarthritis with a sufficient rotator cuff, TSA and TSSR patients have comparable functional outcome, glenoid component version, and lateral glenohumeral offset...

BACKGROUND: Increasing methicillin resistance and recognition of Propionibacterium acnes as a cause of infection in shoulder arthroplasty has led to the adoption of local vancomycin powder application as a more effective method to prevent expensive periprosthetic infections. However, no study has analyzed the cost effectiveness of vancomycin powder for preventing infection after shoulder replacement. METHODS: Cost data for infection-related care of 16 patients treated for deep periprosthetic shoulder infection was collected from our institution for the break-even analysis...

INTRODUCTION: At present, surgical treatment of comminuted radial head fractures without associated instability continues to be controversial. When anatomical reconstruction is not possible, radial head excision is performed. However, the appearance of long-term complications with this technique, along with the development of new radial head implants situates arthroplasty as a promising surgical alternative. The purpose of the present study was to compare the mid-term functional outcomes of both techniques...
