This editorial introduces a series of interviews with the pioneers of Nephrology. It's a story that speaks by itself, given the thousands of people that are now alive thanks to the remarkable advances in renal replacement therapies such as dialysis, and kidney transplantation but also the many scientific advances in our understanding of the pathophysiology and treatment of kidney diseases worldwide.The interviews that we have selected for this series are, however, not dealing with their achievements, and their success; they try to pass on to future generations the idea of how they were, why they were passionate, what they loved, and, not last, where they found poetry in our profession...

BACKGROUND: Glenoid replacement in cases of severe glenoid retroversion (RV) or eccentric wear is challenging. The aim of this study was to evaluate different treatment methods under standardized conditions to assist surgeons in the decision-making process. METHODS: Three treatment options for severe glenoid RV (15°) were compared: (1) no RV correction; (2) complete RV correction; (3) no RV correction and implantation of a posterior augmented glenoid (PAG). A highly standardized implantation protocol using artificial glenoid bones (five per group) was chosen, and a physiologic shoulder movement was applied in a biomechanical setting...

BACKGROUND: Bony defect situations are a common problem in revision arthroplasty of the shoulder and are the cause of the complexity of the procedure. Aseptic and septic loosening as well as difficult implant removal can result in humeral and/or glenoid bone loss. PLANNING: A careful preoperative imaging is needed to estimate the extent of the bony defect and to enable precise planning of the bone reconstruction and the required implants. However, the size of the defect needs to be re-evaluated intraoperatively after removal of the implant components and any larger defects have to be addressed appropriately...

IMPLANT DESIGNS: Within the last 50 years, implants for shoulder replacement have developed rapidly. Monobloc-stems in few sizes were changed to modular implant systems that allow for an individual adaption of the stem, as well as adaption of the humeral head component according to the specific anatomic situation of the patient. Moreover, stemless und short stem implants are available, which may highly simplify primary implantation, especially in posttraumatic cases as well as in revision cases with a need for removal or change of the implants...

A crutch is prescribed to permit the patient to walk safely and independently immediately after total hip replacement (THR) surgery. Purpose of this study is to evaluate the influence of the crutch setup on upper limbs biomechanics, including shoulder joint kinematics and kinetics parameters that will be evaluated to detect possible differences related to the crutch length. Thirty patients were randomly assigned to elbow flexed (EF) or elbow extended (EE) forearm crutch setup. Subjects were asked to walk on the laboratory path, instrumented with motion tracking system and force platforms...

Understanding trends in reimbursement is critical to the financial sustainability of orthopedic practices. Little research has examined physician fee trends over time for orthopedic procedures. This study evaluated trends in Medicare reimbursements for orthopedic surgical procedures. The Medicare Physician Fee Schedule was examined for Current Procedural Terminology code values for the most common orthopedic and nonorthopedic procedures between 2000 and 2016. Prices were adjusted for inflation to 2016-dollar values...

INTRODUCTION: Postdischarge disposition after shoulder replacement lacks uniform guidelines. The goal of this study was to identify complication and readmission rates by discharge disposition and determine whether disposition was an independent risk factor for adverse events, using a statewide database. METHODS: Data from the California Office of Statewide Health Planning and Development discharge database were used. Patient information was assessed, and 30- and 90-day complication rates were identified...

Introduction: Currently, it is challenging to treat giant cell tumor (GCT) of distal radius. For Campanacci grade III or recurrent GCTs, en bloc resection has been accepted as a better treatment option. Although numerous methods are available for reconstruction, all of them have some limitations in joint function and complications. In this study, our aims were to treat the GCT of distal radius with uncemented three-dimensional (3D)-printed prosthesis and to present and evaluate the surgical techniques and short-term outcomes...

The aim of this experiment was to study the effect of total replacement of oat hay by rosemary distillation residues (RR) on growth, carcass characteristics and meat quality of Barbarine lambs. A total of 21 lambs were divided into three groups. The control group (C) was offered 600 g of oat hay; the RR87 and RR60 groups received 600 g of pellets containing 87% and 60% of RR, respectively. The CP content was 9% and 14% for RR87 and RR60, respectively. All animals were supplemented by 600 g of concentrate. After 77 days of fattening, lambs were slaughtered...

Patients with shoulder pain are commonly seen in adult primary care, and are typically referred to musculoskeletal specialists when their symptoms are persistent. Rotator cuff disorders (RCD) most commonly underlie non-traumatic shoulder pain in adults, and glenohumeral osteoarthritis (GHOA) has been considered to be relatively uncommon (Nakagawa et al., J Shoulder Elb Surg 8:580-584, 1999). Our impression has been that GHOA affects significant numbers of patients, is less well studied, and may be under recognized...

BACKGROUND: Bone loss in shoulder instability is a well-recognized cause of failure after stabilization surgery. Many approaches have been described to address glenoid bone loss, including coracoid transfer. This transfer can be technically difficult and has been associated with high complication rates. An ideal alternative to coracoid transfer would be an autologous source of fresh osteochondral graft with enough surface area to replace significant glenoid bone loss. The distal clavicle potentially provides such a graft source that is readily available and low-cost...

PURPOSE: Like in many other joints, current shoulder replacement designs aim at bone preservation. According to the literature available, stemless total shoulder arthroplasty (TSA) compares favourably with stemmed designs in terms of function and survivorship of the implant. However, long-term results of stemless shoulder arthroplasty are still missing. Therefore, the aim of the present study was to evaluate long-term results of stemless anatomical TSA. METHODS: Between 2006 and 2009, 51 shoulders in 46 patients were resurfaced using the Biomet Total Evolutive Shoulder System (TESS)...

BACKGROUND: Stemless shoulder arthroplasty is a fairly new concept. Clinical and radiological follow-up is essential to prove implant safety and concept. This prospective single-centre study was performed to evaluate the influence of radiological changes on clinical mid-term outcome following stemless humeral head replacement with hollow screw fixation. METHODS: Short- and mid-term radiological and clinical evaluations were performed in 73 consecutive shoulders treated mainly for idiopathic and posttraumatic osteoarthritis with stemless humeral head arthroplasty including 40 hemi- (HSA) and 33 total shoulder arthroplasties (TSA)...

BACKGROUND: Gestational diabetes is a type of diabetes that occurs during pregnancy. Women with gestational diabetes are more likely to experience adverse health outcomes such as pre-eclampsia or polyhydramnios (excess amniotic fluid). Their babies are also more likely to have health complications such as macrosomia (birthweight > 4000 g) and being large-for-gestational age (birthweight above the 90th percentile for gestational age). Current clinical guidelines support elective birth, at or near term in women with gestational diabetes to minimise perinatal complications, especially those related to macrosomia...

BACKGROUND: Preoperative computed tomography (CT) measurements of glenoid version and inclination are recommended for planning glenoid implantation in shoulder arthroplasty. However, current manual or semi-automated 2-dimensional (2D) and 3-dimensional (3D) methods are user-dependent and time-consuming. We assessed whether the use of a 3D automated method is accurate and reliable to measure glenoid version and inclination in osteoarthritic shoulders. METHODS: CT scans of osteoarthritic shoulders of 60 patients scheduled for shoulder arthroplasty were obtained...

Osteoarthritis of the shoulder is caused by progressive cartilage wear of the glenohumeral joint. Its prevalence is increasing due to our ageing population and it may affect up to one-third of people over 60 years of age. Patients usually complain of pain with restricted shoulder movement and function. Initial treatment should be non-operative, such as activity modification, oral analgesics (e.g. non-steroidal anti-inflammatories) and possibly physical therapy or corticosteroid injections. Patients with ongoing severe pain and functional restriction despite non-operative treatment would be candidates for surgery, usually a shoulder replacement...
