The inter-relationship of clinical parameters in congenital talipes equinovarus: relevance to pathological anatomy and clinical classification

Background  

The clinical features that define congenital talipes equinovarus (CTEV) are the presence of four principal components, equinus, varus, adductus and cavus. Classification systems in CTEV often include a form of assessment of these components and also other concurrent clinical parameters which feature in the condition.     

Predictors of successful outcomes in first web space contracture release

Background  

The success of a first web space contracture release is dependent on the individual parameters of thumb movement. Examining these parameters individually, it is possible to predict which components are important for providing successful outcomes.     

All-Polyethylene Tibial Components in Obese Patients Are Associated With Low Failure at Midterm Followup

Background  

In the United States, the obese population has increased markedly over the last four decades, and this trend continues. High patient weight places additional stress on TKA components, which may lead to increased polyethylene wear, osteolysis, radiolucencies, and clinical failure. Metal-backed tibial components and all-polyethylene tibial components in the general population have comparable osteolysis and failure, but it is unclear whether these components yield similar osteolysis and failure in obese patients.

The objective of the present study is to provide an overview of flexor tendon rehabilitation outcome measures with respect to ICF components. Furthermore, it aims to investigate to which extent current assessments measure aspects of health according to these components primarily focussing on activity and participation.     

Pelvic Discontinuity Treated With Custom Triflange Component: A Reliable Option

Background  

Pelvic discontinuity is an increasingly common complication of THA. Treatments of this complex situation are varied, including cup-cage constructs, acetabular allografts with plating, pelvic distraction technique, and custom triflange acetabular components. It is unclear whether any of these offer substantial advantages.     

Tantalum Augments for Paprosky IIIA Defects Remain Stable at Midterm Followup

Background  

Initial reports with short-term followup of porous tantalum acetabular components and augments for Paprosky IIIA acetabular defects demonstrate high hip scores, low rates of aseptic loosening, and low rates of complications. However, longer-term followup with a larger cohort is needed to determine the durability of these reconstructions.     

Influence of total knee arthroplasty on patellar kinematics and contact characteristics

Purpose  

Femoro-patellar complications are one of the most common problems after total knee arthroplasty (TKA). TKA components that reduce patellar loads and preserve physiological patellar kinematics should reduce these problems. Therefore, we evaluated the patellar kinematics and the retro-patellar contact characteristics in both the intact knee and in the TKA-knee.     

A review of the composition,characteristics, and effectiveness of barrier mesh prostheses utilized for laparoscopic ventral hernia repair

Background  

The objective of this review was to provide an overview of the components that comprise each of the eight barrier mesh prostheses commonly utilized for LVHR and to review the current literature related to the characteristics and effectiveness of these materials to guide the general surgeon in selecting the most appropriate material for LVHR.     

Weight of Polyethylene Wear Particles is Similar in TKAs with Oxidized Zirconium and Cobalt-chrome Prostheses

Background  

The greater lubricity and resistance to scratching of oxidized zirconium femoral components are expected to result in less polyethylene wear than cobalt-chrome femoral components.     

Surgical Technique: A Cup-in-Cup Technique to Restore Offset in Severe Protrusio Acetabular Defects

Background  

Severe medial and/or superior defects encountered in revision THA are currently managed with jumbo (≥ 66 mm) acetabular components and modular augments, with reconstruction cages, or with the cup-cage technique. Preoperative planning can indicate when these techniques may not restore vertical and horizontal offset. Failure to restore offset can lead to impingement, leg length inequality, abductor weakness, and dislocation.     

Effect of erythrocytes on brain water content and haem oxygenase-1 expression in rats with traumatic intracerebral haemorrhage

Background  

Studies have demonstrated that brain oedema formation following spontaneous intracerebral haemorrhage is associated with substances derived from blood clots or blood components. However, these studies did not completely reveal the role of blood components in brain oedema formation following traumatic intracerebral haemorrhage (TICH). Here, we explore the role of erythrocytes in brain oedema development by studying the effect of erythrocytes on brain water content (BWC) and expression of haem oxygenase-1 (HO-1) in rats with TICH.     

Rives-Stoppa incisional hernia repair combined with laparoscopic separation of abdominal wall components: a novel approach to complex abdominal wall closure

Background  

The Rives-Stoppa incisional hernia repair is the gold standard for mesh repair of complex incisional hernias. The risk of infection can be reduced if fascia is closed over the prosthetic mesh. Fascial closure in large defects may require extensive dissection and can result in devascularization of the overlying skin and denervation of the abdominal wall musculature. Laparoscopic components separation minimizes these risks while facilitating anterior fascial closure. The combined technique of Rives-Stoppa repair augmented by laparoscopic separation of abdominal wall components has not previously been reported.     

A Comparison between Robotic-assisted and Manual Implantation of Cementless Total Hip Arthroplasty

Background  

The benefits of robotic techniques for implanting femoral components during THA are still controversial.     

Potential of exogenous cartilage proteoglycan as a new material for cartilage regeneration

Background  

Although proteoglycan (PG) is one of the major components of cartilage matrices, its biological function is not fully elucidated.     

Revisions of Extensive Acetabular Defects with Impaction Grafting and a Cement Cup

Background  

Loosening of acetabular components often leads to bony defects. Management of extensive acetabular bone loss in hip revision arthroplasty can be a tremendous challenge.     

A Comparison of Two Implant Systems in Restoration of Hip Geometry in Arthroplasty

Background  

Restoration of hip offset and leg length during THA is often limited by available implant geometries. The recent introduction of femoral components with a modular junction at the base of the neck (two modular junction components) has expanded the options to restore femoral offset and leg length.     

Effects of TJN-598, a new selective phosphodiesterase type IV inhibitor on anti-Thy1 nephritis in rats

Background  

Phosphodiesterase type IV (PDEIV) plays an important role in the immune response and inflammation. However, it is well known that classical PDEIV inhibitors have systemic side effects, so the clinical and chronic use of these agents as therapy for glomerulonephritis is difficult. This study was performed to elucidate the anti-nephritic effects of TJN-598, a new chemical compound derived from herbal components, on experimental mesangial proliferative glomerulonephritis.
