Multiplier vs SonoHipAngles

The Multiplier App automates calculations to predict mature height and bone length in children. This method was created originally in Baltimore at the University of Maryland and subsequently developed at the International Center for Limb Lengthening (ICLL), Rubin Institute for Advanced Orthopedics (RIAO), Sinai Hospital of Baltimore. We have taught the Multiplier Method for more than 19 years at our annual Baltimore Limb Deformity Course (http://www.DeformityCourse.com). These calculations are typically performed by hand, using various formulae. Certain calculations are easy, but others involve more complicated formulae. Utilizing this app will reduce the time needed for these routine calculations and decrease errors. You need only input certain data (sex, age, length) and the app will calculate the answer by using the appropriate Multiplier formula. The Multiplier App will allow you to make the following calculations: LOWER EXTREMITY · Limb Length Discrepancy (LLD) (Congenital) · LLD (Developmental) · Growth Remaining · Bone Length · Timing of Angular Correction · Timing of Epiphysiodesis · Comprehensive (Congenital) LLD and Epiphysiodesis · Scanogram Calculations (Calculates femur/tibia lengths, overall limb length discrepancy, and amount/side of femur/tibia discrepancies) UPPER EXTREMITY · LLD (Congenital) · LLD (Developmental) · Growth Remaining · Bone Length Height and CDC Growth Charts (Calculates height at maturity, calculates height at every age, and plots the patient’s height and weight on the CDC growth charts) ACHONDROPLASIA · Height · Sitting Height · Leg Length Fetus (Calculates the length of tibia or femur at birth and maturity) FOOT · Foot Length · Foot Length Discrepancy · Foot Height · Foot Height Discrepancy Spine (Calculates sitting height at maturity) Oblique Plane Deformity (Calculates magnitude, orientation, and direction of an oblique plane deformity) Inclined Osteotomy (Calculates the rotational orientation and the vertical inclination of the osteotomy) This app also provides the following additional resources: · Bone Age: Elbow and Hand (Shows how to determine skeletal age by using radiographs of the elbow or hand) · Figures that show the standard measurements for the lower limb and foot · The multiplier formulae that the app uses to perform the calculations · Tables that show the multiplier values that are used in the formulae · Figures that show the Solomin Foot Analysis (Deformity correction planning for the midfoot, hindfoot, and ankle using reference lines and angles provided by Dr. Leonid Solomin) · Figures that show the development of the apophyses, epiphyses, and bones · Bibliography · User guide DISCLAIMER: No growth prediction method is 100% accurate; this App is not a substitute for sound and careful clinical judgment.

Developmental Dysplasia of the Hip (DDH) encompasses a spectrum of conditions where the hip joint is improperly formed, ranging from a mild acetabular shallowness to full dislocation. Early detection of DDH is crucial for effective management and prevention of long-term complications such as pain, limited mobility, or early-onset osteoarthritis. Ultrasonography, rather than X-ray, is the preferred method for diagnosing DDH in infants, especially under the age of 6 months. Ultrasound provides a non-invasive and radiation-free way to visualize the soft tissues, cartilage, and bones in real time. The Graf method is the most widely used technique, where two critical angles—alpha (α) and beta (β)—are measured to assess the development of the acetabulum and classify the hip's condition.This application is designed to aid healthcare professionals—especially radiologists, orthopaedic surgeons—in evaluating DDH by calculating the alpha (α) and beta (β) angles quickl from saved ultrasound images of the patient hip. Provide instant visual feedback by color-coding the angles:Alpha angle (α): red, Beta angle (β): yellow. Automatically also classify the hip joint based on the Graf method Type I,Type IIa/b,Type IIc,Type III, helping clinicians to have a quick glimpse and visualise the relationship between the angles ,real time.Healthcare professionals, particularly in busy departments, can save significant time by quickly loading ultrasound images and automating angle calculations, identify abnormal hips on the go . App can also be used as a training tool for medical students, residents, and junior clinicians, teaching them how to recognise key landmarks, make accurate measurements, and classify DDH using ultrasound images. By rapid visually displaying the measurements on the screen and generating easy-to-understand images, app helps clinicians explain the condition and its severity to parents. App offers α and β angle measurement by dragging points on the ultrasound image to key anatomical landmarks, forming lines that define the acetabular roof and cartilaginous roof. The app automatically calculates the angles and classifies the hip condition based on these measurements in real-time. Important feedback that help allow the user to adjust draggable points and see immediate changes in the angle values helping to fine-tune the position of the lines and target the preferred anatomical landmarks of the ultrasound image more efficiently. User-friendly interface, and reliable classification system based on Graf’s classification that streamline the diagnostic process, and improved overall workflow in clinical practice. Disclaimer. Regarding its plausibility app offers no diagnosis or treatment. App provide an early indication that further evaluation may be warranted by Speciality Doctor. Explicitly is announced that the apps are not for diagnosis. Clinical judgment and experience are required to properly use the software. App alone do not replace an M.D. or specialist. All information received from the App output must be reviewed before any attempted treatment. The software is not for primary image interpretation. Any influence to the operators in making decisions remains user own responsibility and experience. App does not dispense medical advice. Patient should seek a doctor’s advice in addition using the app and /or before making any medical decisions for themself. Never substitute or replace doctors advice or change treatment modalities based on any measured outcome. App indicated for assisting healthcare professionals for scientific and research reason. Clinical judgment and experience are required to properly use the app and further research and validation is pending in coming future.
