Shoulder replacement

Ran Schwarzkopf, Erik Schnaser, Taiki Nozaki, Yasuhito Kaneko, Michael J Gillman
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...

Radial head fractures are common injuries, occurring mostly in active young people 85%. Treatment of the more complex radial head fractures (Mason type III and IV), appear to be challenging and remain a subject of controversy. Replacement of the radial head with a metal prosthesis imitates the stabilizing role of the radial head and has been considered as the treatment of choice. However, long-term results are scarce. We report our mid to long-term (mean 9.4 year) clinical and radiographic results after insertion of a Judet Bipolar Radial Head prosthesis...

OBJECTIVE: Multifocal osteonecrosis is rare. A zone of epiphyseal bone-marrow necrosis of three or more joints characterizes it. The most common risk factors are glucocorticoids intake and alcoholism. However, there is a series of other causes that could be incriminated in osteonecrosis, among which antiphospholipid syndrome. This case report, illustrates a primary antiphospholipid syndrome with only one clinical manifestation: multifocal osteonecrosis. OBSERVATIONS: A 30-year-old woman, with a medical history of left total hip replacement (THR), presents with severe right coxalgia and pain in both knees and shoulders...

Many patients prioritize the ability to return to sports following shoulder replacement surgeries, including total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA), and hemiarthroplasty (HA). While activity levels after hip and knee replacements have been well-established in the literature, studies on this topic in the field of shoulder arthroplasty are relatively limited. A review of the literature regarding athletic activity after shoulder arthroplasty was performed using the PubMed database...

Simulation is a rapidly developing field in medical education. There is a growing need for trainee surgeons to acquire surgical skills in a cost-effective learning environment to improve patient safety and compensate for a reduction in training time and operative experience. Although simulation is not a replacement for traditional models of surgical training, and robust assessment metrics need to be validated before widespread use for accreditation, it is a useful adjunct that may ultimately lead to improving surgical outcomes for our patients...

INTRODUCTION: Total shoulder arthroplasty (TSA) has become a popular and successful surgery to treat advanced glenohumeral arthritis, rotator cuff arthropathy, and proximal humerus fractures. Historical data is available investigating the epidemiology of total shoulder arthroplasty with regard to patient characteristics, outcomes, and complications; however, there is a lack of studies investigating the most recent and up to date national trends related to shoulder replacement. The purpose of this study was to evaluate changes in the annual incidence, various demographics, and complications of TSA in America...

Cutaneous functional units (CFUs) are fields of skin that functionally contribute to range of motion (ROM) at an associated joint. When replaced with scar tissue, the skin is less extensible and may result in loss of movement at the joint. Consideration of the amount of CFU affected by burn injury is increasingly being used to predict the development of burn scar contracture (BSC) in burn survivors. Previous work established that, in adults, burn rehabilitation time per CFU was the greatest predictor of preventing BSC...

Acellular human dermal matrix allografts are now being used to augment and sometimes replace severely damaged rotator cuff tissue. I have been interested in this important aspect of orthopaedics for 15 years and am pleased to have the opportunity to share my personal reflections of some of the highlights in science and the literature that helped get to the point now where we can expect greater than 80% healing even in these difficult cases of revision after massive failed cuff repair. The field of tissue engineering will certainly be a critical part of our rotator cuff surgical future...

BACKGROUND: A porous tantalum glenoid component for total shoulder replacements was introduced in 2003 to promote biologic ingrowth. However, reports of component failure prompted design modifications. The purpose of this study is to present the largest series to date, of TSR with the second-generation Trabecular Metal™ glenoid component. METHOD: A radiologic and clinical evaluation of the second-generation TM glenoid was conducted in consecutive cases of 76 shoulders (66 patients) with a mean follow-up of 43...
