Arman Boromand, Safa Jamali, João M Maia
Core-Modified Dissipative Particle Dynamics (CM-DPD) with a modified depletion potential and full hydrodynamics description is used to study non-equilibrium properties of colloidal gels with short range attraction potentials at an intermediate volume fraction (ϕ = 0.2) under start-up shear deformation. Full structural and rheological analysis using the stress fabric tensor complemented by bond number and bond distribution evolution under flow reveals that similarly to dilute colloidal gels, flow-induced anisotropy and strain-induced stretching of bonds are present during the first yielding transition...

REVIEW
Dror Paley
Fibular hemimelia presents with foot deformity and leg length discrepancy. Previous classifications have focused on the degree of fibular deficiency rather than the type of foot deformity. Published methods of surgical reconstruction have often failed due to residual or recurrent foot deformity. The purpose of this report is to introduce new classification and reconstruction methods. The Paley SHORDT procedure is used to stabilize the ankle when there is a hypoplastic distal fibula with a dynamic valgus deformity...

BACKGROUND: In treating patients with cervical myelopathy, surgical approach may be dictated by sagittal balance, highlighting the need for accurate pre-operative assessment. Magnetic Resonance Imaging (MRI) is widely-recognized for its utility in the diagnosis and surgical planning of cervical myelopathy. Plain radiographs (X-rays) are a reliable tool to assess bony alignment. However, they may not always be included in standard pre-operative evaluation, especially in an era of restricted payer-environments...

STUDY DESIGN: This is a case-series. OBJECTIVE: To evaluate the clinical and radiologic outcomes of posterior vertebral column resection (PVCR) for treatment of posttubercular kyphosis in upper thoracic spine and cervicothoracic junction (CTJ). SUMMARY OF BACKGROUND DATA: Surgical management of severe posttubercular kyphosis in upper thoracic spine or CTJ is challenging. A new technique that combines PVCR and intraoperative manual traction in a single procedure, was developed to maximize the correction rate and minimize the risk of dural buckling and spinal cord injury...

An instantaneous phase shifting deflectometry measurement method is presented and implemented by measuring a time varying deformable mirror with an iPhone <sup>®</sup> 6. The instantaneous method is based on multiplexing phase shifted fringe patterns with color, and decomposing them in x and y using Fourier techniques. Along with experimental data showing the capabilities of the instantaneous deflectometry system, a quantitative comparison with the Fourier transform profilometry method, which is a distinct phase measuring method from the phase shifting approach, is presented...

Fei Sun, Zhaoliang Cao, Yukun Wang, Caihua Zhang, Xingyun Zhang, Yong Liu, Quanquan Mu, Li Xuan
Almost all the deformable mirror (DM) based adaptive optics systems (AOSs) used on large aperture telescopes work at the infrared waveband due to the limitation of the number of actuators. To extend the imaging waveband to the visible, we propose a DM and Liquid crystal wavefront corrector (DM/LCWFC) combination AOS. The LCWFC is used to correct the high frequency aberration corresponding to the visible waveband and the aberrations of the infrared are corrected by the DM. The calculated results show that, to a 10 m telescope, DM/LCWFC AOS which contains a 1538 actuators DM and a 404 × 404 pixels LCWFC is equivalent to a DM based AOS with 4057 actuators...

BACKGROUND: Nasal deformity associated with cleft lip and palate is a highly challenging reconstructive problem in rhinoplasty. In the literature, several operative solutions and evaluation methods have been described, however these do not offer a standard procedure for the surgeon. Our aim was to standardize our surgical technique-as much as the uniqueness of each case allowed it-based on the most frequent deformities we had faced; and to evaluate our results via a postoperative patient satisfaction questionnaire...

This study was carried out to evaluate the benefits of personalized three-dimensional printing as an aid to the performance of surgery for the correction of spinal deformity in children with myelomeningocele. We performed a retrospective review to include all such children for whom personalized three-dimensional spine models were used for surgical planning (group A) and compared them through subjective and objective criteria to a similar group that had no models (group B). The seven children in group A were younger and had more complex deformities than the 10 children in group B...

#11
R P L Wisse, N Soeters, D A Godefrooij, N G de Koning-Tahzib
Keratoconus is a corneal disease with onset typically occurring during puberty or early adulthood. The cornea progressively thins and acquires a cone-like shape which negatively affects visual acuity. In the early stages, visual acuity can be corrected with glasses or contact lenses. In more advanced cases, a corneal transplant is ultimately indicated to restore visual acuity. Corneal cross-linking (CXL) is a treatment given at a relatively early stage that protects patients against deterioration of visual acuity and further corneal deformation in progressive cases of keratoconus...

BACKGROUND: Adolescent idiopathic scoliosis is a complex three-dimensional deformity of the spine characterized by deformities in the sagittal, coronal, and axial planes. Spinal fusion using pedicle screw instrumentation is a widely used method for surgical correction in severe (coronal deformity, Cobb angle > 45°) adolescent idiopathic scoliosis curves. Understanding the anatomic difference in the pedicles of patients with adolescent idiopathic scoliosis is essential to reduce the risk of neurovascular or visceral injury through pedicle screw misplacement...

Kyoko Ohno-Matsui
Pathologic myopia (PM) is the only myopia that causes the loss of best-corrected visual acuity. The main reason for best-corrected visual acuity loss is complications specific to PM, such as myopic maculopathy, myopic traction maculopathy, and myopic optic neuropathy (or glaucoma). The meta-analyses of the PM study group (META-PM study) made a classification system for myopic maculopathy. On the basis of this study, PM has been defined as eyes having atrophic changes equal to or more severe than diffuse atrophy...

Scoliosis is a lateral curvature in the normally straight vertical line of the spine, and the curvature can be moderate to severe. Different treatment can be used based on severity and age of subjects, but most common treatment for this disease is using orthosis. To design orthosis types of force arrangement can be varied, from transverse loads to vertical loads or combination of them. But it is not well introduced how orthoses control scoliotic curve and how to achieve the maximum correction based on force configurations and magnitude...

We report a case involving a young female patient with severe mandibular retrognathism accompanied by mandibular condylar deformity that was effectively treated with Le Fort I osteotomy and two genioplasty procedures. At 9 years and 9 months of age, she was diagnosed with Angle Class III malocclusion, a skeletal Class II jaw relationship, an anterior crossbite, congenital absence of some teeth, and a left-sided cleft lip and palate. Although the anterior crossbite and narrow maxillary arch were corrected by interceptive orthodontic treatment, severe mandibular hypogrowth resulted in unexpectedly severe mandibular retrognathism after growth completion...

"A smile is happiness you'll find right under your nose"- Tom Wilson. This quote holds true just for patients, not for surgeons. The correction of the nose always poses a challenge to the cosmetic surgeon. Deformities of the external and internal nose may be congenital or acquired and may be secondary to soft tissue and/or osseo-cartilaginous abnormalities, leading to aesthetic and/or functional consequences. Alar flare poses a common problem, sometimes alone and sometimes in conjunction with other external deformities...

Flexion contracture deformities, as well as severe varus and valgus deformities of the knee joint, accompany osteoarthritis or rheumatoid arthritis (RA). In particular, severe flexion contracture deformity of the knee joint is often found in patients with RA, which renders them nonambulatory. This report describes a 26-year-old female patient diagnosed with RA 10 years ago. She had chronic joint pain, severe flexion contracture, valgus deformity in both knees, and limited range of motion in both knees and became nonambulatory...
