BACKGROUND: The treatment of a tuberous breast deformity has changed over the years, with a large variety of procedures described. However, maintaining a long-lasting breast contour is an ongoing challenge. The aim of this study was to evaluate the long-term results of tuberous breast corrections, focusing on the incidence of secondary procedures and patient satisfaction. MATERIALS AND METHODS: Forty-six patients who underwent correction of a tuberous breast deformity from 2000 through 2013 were considered...

The Cotton osteotomy or opening wedge medial cuneiform osteotomy is a useful adjunctive flatfoot reconstructive procedure that is rarely performed in isolation. The Cotton procedure is relatively quick to perform and effectively corrects forefoot varus deformity after rearfoot fusion or osteotomy to achieve a rectus forefoot to rearfoot relationship. Proper patient selection is critical, because preoperative findings of medial column joint instability, concomitant hallux valgus deformity, or degenerative joint disease of the medial column might be better treated with arthrodesis of the naviculocuneiform or first tarsometatarsal joints...

BACKGROUND: Congenital talipes equinovarus (CTEV), also known as clubfoot, is common congenital orthopedic foot deformity in children characterized by four components of foot deformities: hindfoot equinus, hindfoot varus, midfoot cavus, and forefoot adduction. Although a number of conservative and surgical methods have been proposed to correct the clubfoot deformity, the relapses of the clubfoot are not uncommon. Several previous literatures discussed about the technical details of Ponseti method, adherence of Ponseti protocol among walking age or older children...

The curvature of the nasal septum (NS) is one of the most widespread deformations of the facial skeleton. The objective of the present study was to substantiate the principles of and develop the rationale for the surgical correction and conservative treatment of this condition based on the morphological features of various types of deflection of the nasal septum. We have undertaken the morphological analysis of the osseous and cartilaginous structures determining the type and the shape of the curvature of the nasal septum together with the clinical analysis of different morphological variants of the deflection of the nasal septum making use of the R...

Cavovarus deformity can be classified by the severity of malalignment ranging from a subtle and flexible to a severe and fixed cavovarus deformity of the foot.In the mild cavovarus foot, careful clinical assessment is required to identify the deformity.Weight-bearing radiographs are necessary to indicate the apex of the deformity and quantify the correction required.Surgery is performed when conservative measures fail and various surgical procedures have been described, including a combination of soft-tissue releases, tendon transfers and osteotomies, all with the aim of achieving a plantigrade and balanced foot...

Correction manoeuvres are as important as the other issues such as hardware selection, graft options, fusion and osteotomy techniques in the surgical treatment of spinal deformities.The property of materials demonstrating both viscous and elastic characteristics when undergoing deformation is called visco-elasticity. Purely elastic materials change in shape with a stress, and go back to their initial form when the stress is removed. However, visco-elastic materials, like the spine, may protect their new formation unless a back stress is applied...

Femoral rotational malalignment is associated with pain and functional disability and may be a contributing factor to hip impingement as well as to instability. In general, the deformity can be addressed surgically by rotational osteotomy. However, the anatomic location of the deformity is debated. The goal of the present study was to narrow down the anatomic site of deformity using the lesser trochanter (LT) as an additional landmark. One hundred and eight patients underwent computer tomography (CT)-based rotational analysis of their lower extremities...

OBJECTIVE: The majority of uncomplicated toddler fractures of the tibia (toddler's fractures) do not need an orthopaedic surgeon's intervention or follow-up. However, inexperienced emergency room physicians, general practitioners and orthopaedic trainees and surgeons understandably defer to a cautious approach of referral and subsequent frequent clinical and radiographic follow-up. An evidence-based pathway can help prevent this overtreatment, reduce unnecessary radiation exposure and decrease the financial burden on families and the healthcare system...

We improve multiphoton structured illumination microscopy using a nonlinear guide star to determine optical aberrations and a deformable mirror to correct them. We demonstrate our method on bead phantoms, cells in collagen gels, nematode larvae and embryos, Drosophila brain, and zebrafish embryos. Peak intensity is increased (up to 40-fold) and resolution recovered (up to 176 ± 10 nm laterally, 729 ± 39 nm axially) at depths ∼250 μm from the coverslip surface.

BACKGROUND: Although standard fixation of proximal interphalangeal (PIP) arthrodesis by K-wire is relatively inexpensive and well established, it does have some drawbacks, making newer fixation devices interesting. The aim of this study was to clinically and radiologically assess the operative correction of the lesser toe deformation in the form of a PIP arthrodesis using a bioabsorbable 2.7-mm fixation screw. METHODS: From January 2011 until October 2013, 34 patients underwent a PIP arthrodesis using the TRIM-IT (Arthrex) 2...

PURPOSE: To investigate the association between corneal biomechanical properties measured with the Ocular Response Analyzer (ORA) and also CorvisST (CST) tonometry, and glaucomatous visual field (VF) severity. METHODS: One hundred forty-six eyes of 91 patients with primary open-angle glaucoma who performed Humphrey Field Analyzer 30-2 or 24-2 SITA-Standard, ORA, and CST within 180 days were included in this multicentral, observational cross-sectional study. The association between ORA parameters (corneal hysteresis [CH] and corneal resistant factor [CRF]), CST parameters (A1 and A2 time, A1 and A2 length, A1 and A2 velocity, A1 and A2 deformation amplitude, highest deformation amplitude, highest concavity time, peak distance, and radius), and other basic parameters (age, intraocular pressure with Goldmann applanation tonometry, central corneal thickness, and axial length) against mean total deviation (mTD) were analyzed using a linear mixed-model and model selection with corrected Akaike Information Criterion (AICc)...

BACKGROUND: Progress in medical branches that has taken place since the first child with Goldenhare syndrome (GS) had been described in 1952 by Maurice Goldenhar, facilitated better understanding of this congenital defect. It also gave new perspectives and the opportunity to achieve satisfactory treatment results, mainly due to development of surgical techniques. DATA SOURCES: Based on the literature and own experience, we discussed the phenotype of presentation of GS, ethiopathogenesis, genetic counselling and treatment with particular emphasis on surgery correction of hemifacial microsomia...

Subtalar arthroereisis has been proved to be an efficient method for correcting flexible adult flatfoot. However, the optimal sinus tarsi implant is still debated and yet to be determined. In the present study, we compared the biomechanical effects of type I and II sinus tarsi implants in stage II adult-acquired flatfoot deformity (AAFD). First, a finite element model of stage II AAFD was established in which virtual surgery of subtalar arthroereisis was simulated. The indexes of plantar stress distribution, peak von Mises of the medial and lateral columns, strain of the medial ligaments and plantar fascia, arch height, talo-first metatarsal angle, calcaneus pitch angle, talonavicular coverage angle, and hindfoot valgus angle were all compared and analyzed...

PurposeThe eyeball and, in particular, the cornea deform in vitro by the application of a distending force like other visco-elastic tissue. If the force is large enough, the cornea strains beyond the elastic range, and a permanent deformation occurs. Such permanent strain is referred to as 'plastic' strain. The phenomenon, however, has never been observed or produced on living tissue. This report seeks to demonstrate that the central radius of a patient's cornea can be altered in a controlled manner designed to correct refractive errors...

BACKGROUND: Sunken upper eyelid is a commonly found deformity among Asians, mostly due to the aging process and excessive orbital fat removal during oriental blepharoplasty procedures. This deformity is frequently accompanied by multiple, poorly defined upper eyelid folds and blepharoptosis. To date, autologous fat graft has been the treatment of choice for this group of patients. However, accurate placement of the graft in the orbital fat is quite challenging, and it can result in contour irregularities when injected into the preseptal plane...

Objective The objective of this study was to identify determinants of health-related quality of life (HRQoL) impairment in patients with systemic lupus erythematosus (SLE). Methods Overall, 101 SLE patients were recruited; 37 healthy subjects and 35 rheumatoid arthritis (RA) patients served as controls. HRQoL was evaluated using three patient reported outcomes (PROs): the Short Form-36 version 2 (SF-36v2) health survey, the fatigue scale version 4 (FACITv4) and the Heath Assessment Questionnaire (HAQ). A large set of demographic and clinical variables, including SLE arthritis subtypes, was evaluated searching for factors independently associated with worse QoL...

Elisabeth Agoritsas, Kirsten Martens
In this work we discuss possible physical origins of non-trivial exponents in the athermal rheology of soft materials at low but finite driving rates. A key ingredient in our scenario is the presence of a self-consistent mechanical noise that stems from the spatial superposition of long-range elastic responses to localized plastically deforming regions. We study analytically a mean-field model, in which this mechanical noise is accounted for by a stress diffusion term coupled to the plastic activity. Within this description we show how a dependence of the shear modulus and/or the local relaxation time on the shear rate introduces corrections to the usual mean-field prediction, concerning the Herschel-Bulkley-type rheological response of exponent 1/2...
