Objective: This study aims to evaluate the efficacy and safety of using a strip-shaped cymba conchae orthosis for the nonsurgical correction of complex auricular deformities. Methods: Clinical data were collected from 2020 to 2021 for 6 patients who underwent correction using a stripshaped cymba conchae orthosis. The indications, corrective effects, and complications associated with use of the orthosis were analyzed. Results: There were four indications for treatment: cryptotia with helix adhesion;cryptotia with grade I microtia;cryptotia with excessive helix thickness;and auricular deformity beyond the treatment time window(≥6 months). Excellent corrective effects were observed in all 6 patients. Complications occurred in one patient, who recovered after symptomatic treatment. Conclusion: The use of a strip-shaped cymba conchae orthosis alone or combined with a U-shaped helix orthosis presents a feasible approach for correcting complex auricular deformities or deformities beyond the treatment time window in pediatric patients.

BACKGROUNDEwing’s sarcoma is a highly malignant primary bone tumor that commonly affectschildren. For young patients, multidisciplinary treatment and limb salvage arerecommended, and surgical plans considering the growth potential and boneactivity after tumor resection are essential.CASE SUMMARYAn 11-year-old Asian boy had a 1-mo history of a right-sided limping gait.Imaging revealed a proximal tumor with bone destruction and physealinvolvement over the right femoral neck. He was diagnosed with stage IV(T1N0M1aG3) Ewing’s sarcoma with bilateral lung metastases. Neoadjuvantchemotherapy decreased the tumor size and confined it to the metaphysealregion. The patient underwent four stages of surgery: wide tumor excision plusreconstruction with vascular fibular bone graft plus internal fixation;repeat openreduction and internal fixation;femoral lengthening with orthosis after physealmaturity;and orthosis removal and bone elongation (approximately 6 cm).Following surgery, he could walk without discomfort and had almost equal-sizedbilateral femoral heads, indicating physis preservation. The surgery wassuccessful, and normal femoral head growth was achieved after completeremission. The patient was able to resume normal activities with equal length ofthe bilateral lower limbs.CONCLUSIONTumor treatment and reconstruction following resection are important in skeletally immature patients with Ewing’s sarcoma to improve quality of life.

Context: Patellofemoral Pain (PFPS) accounts for up to 25% of knee injuries in sports medicine clinics, with up to 91% of symptoms unresolved after conservative treatment at 5 years. The variability of response to treatment reflects its multi-factorial biomechanical etiologies. Bracing has been utilized to modify patellofemoral kinematics, generally by increasing patellofemoral contact area. The DJO Reaction orthosis is unique in its shock-absorbing elastomeric design, which is created to dissipate peak stress and enhance patellar tracking. Objective: To assess whether the DJO Reaction Brace reduces pain and improves functional outcomes in patients with chronic PFPS. Design: Cohort Series. Setting: Academic Sports Medicine Clinic. Patients: Twenty-two individuals between 18 and 40 years old with chronic patellofemoral pain have failed conservative treatment. Intervention: DJO Reaction Brace. Main Outcome Measures: Kujala Anterior Knee Pain Scale, Knee Injury and Osteoarthritis Outcome Score. Results: Seven males and 10 females with an age range of 19 - 39 years old complete the study. At an average follow-up time of 55 days, the Kujala score significantly improves by 9.8%, and KOOS Scores increase by the following statistically significant amounts: symptom 3.2%, pain 10.7%, sports and recreation 12.9%, quality of life 20.2%. Conclusion: The DJO Reaction orthosis reduces knee pain, increases function, and enhances quality of life with individuals with PFPS and is effective in the conservative care of patellofemoral pain syndrome.

Clinicians can provide a means to better distribute the pressure around the foot, and can also correct the biomechanics of the foot by using a customized shoe insole. If detected early enough, orthopedic insoles can correct or prevent further complications. In this study the 3 Dimensional (D) model of the foot was used to fabricate a customized orthosis. The Computed Tomography (CT) images of patient’s foot having no muscle weakness and joint restriction were acquired. The gray intensities corresponding to the bones of the foot from the CT images were 3 dimensionally reconstructed. The 3D model of the foot was then imported into the CAD Software. Boolean operations were carried out in between the 3D foot model and a solid rectangular surface to create a customized foot orthosis. The exact contours and shape of the subject’s foot was acquired using the computerized method of fabricating an orthosis. The novel idea described in this study support, automating the process of designing a customized orthosis with the impression got from the 3 dimensionally modeled feet, thereby reducing the modeling time considerably. The simple technique used in this process will help in giving comfort and stability to the patient’s feet while walking.

The first objective of this paper is to study the influence of the orthotic device on the maximum values of stresses in knee cartilages by using Ansys Workbench 14.5 software and applying the Finite Element Analysis (FEA) on a virtual assembly composed by an orthotic device and osteoarthritic knee (OAK). The second objective consists into quantifying and investigating the nonlinear motion of the human knee joint for OAK patients, with and without the orthotic device mounted on OAK, using tools of dynamics stability analysis. The short Lyapunov Exponents (LEs) are calculated, as measures of human knee and ankle joints stability, based on the experimental time series collected by using the biometrics acquisition system during walking on horizontal and inclined treadmills from a sample of healthy subjects and a sample of patients suffering by OAK disease. The values of LEs obtained for OAK patients are larger on the inclined treadmill than on horizontal treadmill and are larger than those obtained for healthy knees, being associated with more divergence and less stability. The results confirm that the influence of an orthotic device mounted on OAK on its stability is significant, the values obtained for LEs being smaller than those calculated for OAK, and closer to the values of normal knees of patients and of healthy subjects.

Charcot-Marie-Tooth (CMT) disease, which encompasses several hereditary motor and sensory neuropathies, is one of the most common neuro-muscular disorders. 80% of patients having CMT disease are diagnosed with per cavus deformity. orthosis is widespread and varies widely in forms. The paper arises the necessity of habilitation at the earliest possible stage as only a few patients use it. The meta-analysis of 412 scientific papers concerning this problem demonstrates the getting better gate, balance and the stopping CMT progression which is scientifically proven. It is also shown that patients with CMT use low prevalence of orthotics, and demonstrate low compliance of patients (for various reasons), high expectations from this habilitation technique.

Purpose: The purpose of this study was to investigate the potential functional improvement of the spastic-paretic upper extremity of individuals with chronic hemiparesis when using a dynamic wrist-hand orthosis with and without concurrent botulinum toxin type-A (BoNTA) injections into the spastic upper extremity muscles. Methods: A three-year retrospective chart review was conducted on all stroke patients referred to out-patient occupational therapy for an upper extremity rehabilitation program, which included use of a dynamic wrist-hand orthosis (DWHO). Three charts documented concurrent treatment with a DWHO + BoNTA. Eleven charts documented DWHO use without concurrent BoNTA treatment. Pre- and post-intervention outcome measure scores were compared between the two groups. Pre- and post-interven- tion scores were also analyzed irrespective of treatment group. Results: Although improvement approached significance on three of the documented outcome measures when comparing the DWHO + BoNTA and DWHO groups, no statistically significant changes were found.

Halo fixation devices are often employed for critically ill or trauma patients with unstable cervical pathologies. These include fractures, spinal decompression and reconstruction procedures. However, the critical care literature has surprisingly little information in regard to associated complications. Perry and Nickel pioneered the initial halo device in 1959 and soon afterward recognized complications associated with its use [1]. They developed a detailed regimen to prevent abnormal pin placement and infections. The details include pin placement in “safe” zones, specific degrees of torque, and techniques to minimize infection risk. Despite a low death rate, a cerebral brain abscess often leads to prolonged neurological morbidity [2]. Seizures and pneumocranium have also been ascribed to intracranial penetration of halo pins [3,4]. The following describes a patient with cerebral abscess secondary to halo pin penetration. He then developed several other associated complications during hospitalization.

Lower extremity injury and deformity can result from a number of etiologies. Regardless of the underlying cause, the decision to pursue amputation or reconstruction of a lower limb is challenging for both patients and practitioners.This decision is largely dependent on the patient's premorbid health and function, functional goals and preferences,and characteristics and viability of the affected limb. The role of adaptive devices following surgery should never be underestimated. Advances in prostheses and orthoses have provided patients with a wider range of options to consider when deciding between limb reconstruction and amputation. The primary goals of any adaptive device are to improve function, prevent recurrence or ulceration of the defect, and allow for use of conventional footwear and/or clothing.When a lower extremity amputation is indicated, selection of the correct level is of critical importance in order to optimize healing potential and function. Each distinct level has certain inherent prosthetic and orthotic considerations. Likewise,the application of an adaptive device following reconstruction of the lower extremity also has demonstrable benefits and must be tailored to the specific defect and procedure performed. Knowledge of available prosthetic and orthotic options is of considerable importance for the reconstructive surgeon tasked with limb salvage or resurfacing an amputated extremity. This article reviews considerations of various types of lower extremity amputation and reconstruction, and provides a framework for the role of adaptive devices following surgery.
