BACKGROUND: Total knee arthroplasty is an effective treatment for osteoarthritis. Restoration of physiologic varus alignment may restore the native soft tissue tension and improve outcomes. METHODS: Six paired fresh-frozen knee specimens were used to perform total knee arthroplastys. The left and right sides of were randomly assigned to have either a physiologic alignment cut or a standard of care neutral alignment bony cut prior to the implantation. Loads of 100 and 200N were applied at 0, 30, 60, and 90° of flexion and the magnitude of the medial and lateral compartment distraction was measured...

PURPOSE: Rotator cuff tears are a significant clinical problem, with exercise therapy being a common treatment option for patients. Failure rates of exercise therapy may be due to the failure to improve glenohumeral kinematics. Tears involving the supraspinatus may result in altered glenohumeral kinematics and joint instability for internal/external rotation with the arm at the side because not all muscles used to stabilize the glenohumeral joint are functioning normally. The objective of the study is to assess in vivo glenohumeral kinematic changes for internal/external rotation motions with the arm at the side of patients with a symptomatic full-thickness supraspinatus tear before and after a 12-week exercise therapy programme...

PURPOSE: The radius bone has a slight dorsoradial bow that allows for full forearm pronosupination around the ulna. However, radial malunion can lead to reversal of the radial bow and subsequent volar instability of the distal radioulnar joint (DRUJ), predominantly in supination. This study assessed the outcomes of corrective radial osteotomy for volar DRUJ instability after radial malunion in children. METHODS: The charts of 7 children (2 boys and 5 girls) treated with corrective radial osteotomy for volar DRUJ instability after a radius fracture or deformity were reviewed...

The derangement in calcaneal morphology after a fracture can be significant and is often associated with severe soft tissue envelop problems. Medial calcaneal external fixation is useful for early restoration of calcaneal morphology and the corresponding soft tissue envelop. When performed in a stepwise fashion, external fixation can successfully restore normal calcaneal height, length, width, and coronal plane alignment. For severely displaced joint depression and broken tongue-type calcaneus fractures where open treatment is the preferred strategy, early external fixation restores the normal soft tissue tension, allows a stable environment for soft tissue recovery, and facilitates the definitive operation by restoring and maintaining overall calcaneal architecture...

Andrea S Gantner, Lena Braunschweig, Konstantinos Tsaknakis, Heiko M Lorenz, Anna K Hell
BACKGROUND CONTEXT: In several studies, vertical expandable prosthetic titanium rib (VEPTR) implants have shown good scoliosis control in children with the longest reported follow-up (f/u) of 3.6 years. For growing rods, recent studies suggest a decreased efficiency of correction starting just after that time. To our knowledge, no long-term results of children with VEPTR treatment are available. PURPOSE: To evaluate spinal deformity in scoliotic children and to investigate correction potential of VEPTR implants at several time points of treatment, particularly after long-term f/u...

Management of intraarticular distal radius fractures requires precise reconstruction of the articular surface to optimize outcomes. Treatment goals also include restoration of alignment, rotation, and angulation in both the coronal and sagittal planes of the metaphyseal component of these fractures. Surgical management with open reduction and internal fixation with a volar plate is often the preferred method of open treatment. However, a variety of different techniques have been described, and the preferred technique may be determined on an individual basis by the fracture characteristics, patient-dependent factors, or surgeon experience...

Commonly used irrigants do not always eradicate the entire microbial flora in infected root canals. Therefore, several other strategies, such as photodynamic therapy (PDT) have been developed. Photoactivated disinfection is based on the interaction of a photosensitive antibacterial agent and a light source. It uses a nontoxic dye named photosensitizer (PS) and low-intensity visible light. In oxygen presentation, these combine to produce some cytotoxic species. The PS molecules attach to bacteria membrane. Irradiation with a specific wavelength of the light may lead to the production of singlet oxygen, resulting in rupture of the microbial cell wall...

The asymmetric cell divisions necessary for stomatal lineage initiation and progression in Arabidopsis (Arabidopsis thaliana) require the function of the basic helix-loop-helix (bHLH) transcription factor SPEECHLESS (SPCH). Mutants lacking SPCH do not produce stomata or lineages. Here, we isolated a new spch-5 allele carrying a point mutation in the bHLH domain that displayed normal growth, but had an extremely low number of sometimes clustered stomata in the leaves, whereas the hypocotyls did not have any stomata...

Spinal cord injury (SCI) is a devastating condition affecting hundreds of thousands of people worldwide annually. SCI results in activation of the inflammatory response and apoptosis, and generates oxidative stress, which has deleterious effects on the recovery of motor function. Apocynin, an inhibitor of NADPH oxidase, has been demonstrated to improve neuronal functional recovery in rat models of SCI. However, the efficacy of apocynin treatment post-SCI has not been investigated. The aim of this study was to observe the effects of apocynin on the repair of acute spinal cord damage in rats and to examine the potential beneficial effects...
