The Essential Pediatric Musculoskeletal Exam Cathleen S. McGonigle, DO 4/2011 Annual STFM Meeting 2011 Objectives • Develop a plan of incorporating the Essential Pediatric Exam into all Well Child Checks • Review essential exams in Primary Care for newborn/infants, juvenile, and adolescent patients. • Common Conditions seen for each patient age group (Handout) Overview • Newborn & Infant • Adolescents – Extremities – Extremities • Hips • Hip – Spine • Knees • Foot/Ankle • Juvenile – Spine – Extremities • Elbows • Shoulders • Hips – Spine Well Child Checks • Opportunity to incorporate the musculoskeletal exam • Multiple visits in frequent intervals – Lots of Normal for comparison – Catch things early • Systematic Approach to any Musculoskeletal Exam Physical Exam • Inspection – Symmetry, Birth Marks, Gait, hair, etc • Palpation – Bony Landmarks, Soft Tissues • ROM • Neurovascular • Special Testing • Related Areas Newborns & Infants Exam • Inspection • Lower Limbs – Symmetry – In-toeing – Deformities • Metatarsus Adductus – Skin Folds • Femoral Anteversion • Tibial Torsion – Fingers & Toes • Hips • Palpation – DDH • ROM • Spine • NV – Scoliosis • Special Tests Skin Folds • Asymmetry – Developmental Dysplasia of Hip (Congenital Dysplasia of Hip) • 72.7% - Asym.

Little League elbow refers to a problem located over the • A) medial epicondyle • B) lateral epicondyle • C) olecranon • D) capitellum • E) ulnar groove ITE Answer • Right answer: A • Little League elbow is an apophysitis of the medial epicondyle of the elbow. It occurs in throwing athletes between 9 and 12 years of age, and causes elbow pain during throwing. It may also affect velocity and control. It may cause pain and swelling in the arm and/or elbow, but the diagnosis should be considered in throwing athletes with elbow pain even if symptoms are minimal. • Ref: Cassas KJ, Cassettari-Wayhs A: Childhood and adolescent sports- related overuse injuries.

Little League Elbow Little League Elbow Little League Elbow • Phases of Pitching Little League Elbow • Apophysitis – Medical Epicondyle • Causes – Repetitive Throwing – Specific throwing events • Throwing too hard too often • Increasing the number of pitches you throw per week too quickly (pitch counts) • Throwing too many curves or sliders at a young age • Changing to a league where the pitcher's mound is farther away from home plate or the mound is elevated Little League Elbow • Male greater than Female • Pre-puberty - 10-15 years old • Symptoms – Pain around the medial epicondyle – Swelling (possibly) – Pain when throwing overhand – Pain with gripping or carrying heavy objects Little League Elbow • X-ray Little League Elbow • X-ray Little League Shoulder • Growth plate injury of the proximal humerus • Cause: – Overuse and repetitive microtrauma • Presentation: – Diffuse shoulder pain worse with throwing or extremes of shoulder ROM http://www.childrensmemorial.org/depts/sportsmedicine/im ages/LittleLeagueShoulder.gif Little League Shoulder Diagnosis • Plain
