BACKGROUND: The combination of neurologic deformity of the ankle and foot with osteomyelitis is a therapeutic challenge. We investigated the role of Ilizarov with regard to eradication of infection, correction of deformities and improvement of patient function. METHODS: We retrospectively reviewed 77 patients (77 feet) with neurologic deformity of the ankle and foot with osteomyelitis treated sequentially in 3 stages by Ilizarov method. The 3 stages were (1) active debridement and Ilizarov stabilization, (2) further strengthening of Ilizarov fixator and active osteosynthesis consisting of strategies like arthrodesis, osteotomy distraction, bone transport, or combination thereof, (3) consolidation of fusion/regeneration achieved in second stage...

Estrogen deficiency following menopausal provokes alveolar bone loss, remodeling and inflammation. Eugenol is a phenolic compound with wide dental applications and anti-inflammatory properties. In the present study, the potential protective role of eugenol against alveolar bone deformities was investigated in an ovariectomized (OVX) rodent model. Two doses of eugenol (2.5 and 5 mg/kg/d) were administered to OVX animals for 12 weeks. In Serum, markers of bone metabolism and pro-inflammatory cytokines were estimated using ELISA...

Surgical correction of complex foot and ankle deformities secondary to Charcot neuroarthropathy remains a significant surgical challenge. New technological advancements in hardware have allowed for the use of augmented fixation techniques in midfoot deformity correction, including the use of indication-specific locking plates and beaming techniques that offer enhanced stability. Severe hindfoot deformity management can employ the use of internal fixation, including intramedullary hindfoot nails and circular external fixation frames for limb salvage...

Hallux-abducto-valgus or "bunion" surgery is one of the most common surgical procedures for the foot and ankle specialist. As our understanding of the hallux-abducto-valgus deformity has grown, it is becoming clear that the anatomic CORA of the deformity may lie at the tarsometatarsal joint. There is also the component of the 3-dimensional nature of the deformity that may be best addressed at this CORA. With these issues in mind, it was necessary to address the shortcomings of the traditional Lapidus procedure and progress toward more consistent, instrumented steps that could address the 3-dimensional nature of the deformity...

Limb deformity correction has been widely discussed in orthopedic literature with an increasing interest in technologically based surgical strategies. However, principles described by Ilizarov and Paley still form the basis of these newly developing surgical systems. The recent advances and increased use of computers and mobile devices in the medical arena, along with the application of dynamic hexapod external fixation, have allowed for easier and more convenient strategies, leading to a greater outreach and more confidence in the newer surgeon when faced with addressing a patient with a limb deformity...

BACKGROUND: Cement augmentation techniques are standard treatments for osteoporotic vertebral fractures. Compared to vertebroplasty, kyphoplasty is associated with lower rates of cement leak and better deformity correction, however, posterior wall fractures are relative, but not absolute, contraindications for both techniques and hence treatment practices vary among spine centers. PURPOSE: The primary aim of this study was to assess our center's incidence of posterior cement leakage in osteoporotic vertebral fractures with posterior wall injury treated by balloon kyphoplasty...

BACKGROUND: Hindfoot arthritis or significant deformity involving the ankle and subtalar joint (STJ) is a disabling condition with few salvage options. Many surgeons note a decreased STJ fusion rate compared with ankle union when a retrograde nail construct is used. The purpose of this study was to report the STJ fusion rate of tibiotalocalcaneal (TTC) arthrodesis with retrograde nail. METHODS: A chart and radiographic review was performed. TTC fusions performed in patients with osteoarthritis, posttraumatic arthritis, or deformity correction with retrograde nail fixation were included...

Among the less common congenital auricular anomalies are cryptotia, Stahl ear, constricted ear, and macrotia. The vast majority of these occur spontaneously without accompanying syndromes or other deformities. This article provides a comprehensive overview of these anomalies, as well as common techniques to correct these anomalies.

Congenital auricular deformities often can be corrected by neonatal ear molding techniques, which have evolved significantly over a 25-year period with commercially available molding systems now available. Indications for molding and methodology for best optimizing results have been well described in the literature, although recent studies have explored methodology for reduction in the cost of technique and also called for increased awareness among pediatric practitioners of the importance of early institution of therapy...

Background: The management of congenital talipes equino varus (clubfoot deformity) has been transformed in the last 20 years as surgical correction has been replaced by the non-surgical Ponseti method. The Ponseti method, consists of corrective serial casting followed by maintenance bracing, and has been repeatedly demonstrated to give best results - regarded as the 'gold standard' treatment for paediatric clubfoot. Methods: To develop the study protocol Level 2 evidence was used to modify the corrective casting phase of the Ponseti method in children aged up to 12 months...

In this work, a non-reflective boundary condition, the Perfectly Matched Layer (PML) technique, is adapted and implemented in a fluid-structure interaction numerical framework to demonstrate that proper boundary conditions are not only necessary to capture correct wave propagations in a flow field, but also its interacted solid behavior and responses. While most research on the topics of the non-reflective boundary conditions are focused on fluids, little effort has been done in a fluid-structure interaction setting...

BACKGROUND: Recent morphological analyses of vertebrae in patients with scoliosis have revealed three-dimensional (3D) deformities in the vertebral bodies. However, it remains controversial whether these deformities are secondary changes caused by asymmetrical vertebral loading or primary changes caused by aberrant asymmetrical vertebral growth. Furthermore, the difference in vertebral morphology between scoliosis with different pathogeneses remains unclear. This study was aimed to investigate the difference in the coronal asymmetry of vertebral bodies between neuromuscular scoliosis (NS) in Duchenne muscular dystrophy (DMD) and idiopathic scoliosis (IS) using in vivo 3D analysis...

Following the recent establishment of a high-density seismic network equipped with low-cost micro-electro-mechanical system (MEMS) P-wave-alert-device (P-Alert) by the earthquake early warning (EEW) research group at the National Taiwan University, a large quantity of strong-motion records from moderate-magnitude earthquakes (ML > 6) around Taiwan has been accumulated. Using a data preprocessing scheme to recover the dynamic average embedded within the P-Alert data, we adopted an automatic baseline correction approach for the P-Alert accelerograms to determine the coseismic deformation (Cd)...

BACKGROUND: Idiopathic genu valgum is a frequently diagnosed growth disorder in adolescence. Whenever the possibilities of conservative therapy have been exhausted, leg straightening by means of hemiepiphysiodesis has become the standard form of treatment. Because of their flexible screw-plate connection, eight-Plates have been reported in the literature to lead to lower complications regarding implant loosening and fracture compared to other implants. The aim of this retrospective survey was to analyse our own patient population who were treated for genu valgum by means of temporary hemiepiphysiodesis near the knee using eight-Plates to modulate growth...
