The return to work/play progression for concussion treatment. 2. 2 keys to ordering radiographs for knee OA. 3. Updated treatment for knee OA. 4. The three pillars of the female athlete triad. 5. How to write an exercise prescription. UCSF Essentials of Primary Care August 6, 2013 Case #1 40 y/o woman presents to your office for ER follow-up two days after bike accident. Slid out while crossing streetcar tracks on wet city streets. No loss of consciousness. Taken by ambulance to ER. Had trauma work-up including head CT (-). Diagnosed with clavicle fracture, nonoperative tx by orthopaedic surgeon, discharged home. Has headache, fatigue, dizziness, light sensitivity. Trouble staying focused at work, sleeping more than usual. Normal neurologic exam. H/o trauma Headache Fatigue Dizziness Diagnosis: Concussion Light sensitivity Trouble staying focused at work Sleeping more than usual. 1

How would you treat the concussion? Concussion definition 1. Order urgent head CT to rule out subtle post traumatic bleed, return to clinic after CT. 2. Rest from work and biking, return to clinic 1 week. 3. Return to work but rest from biking, return to clinic in a month. 4. Return to work and biking (assuming cleared by orthopaedic surgeon for clavicle fracture). 18% 75% 5% 2% 1 2 3 4 Blow to head, neck, body force to brain Rapid onset of neurologic impairment Symptoms represent metabolic change in CNS Standard neuroimaging normal (CT, MRI) Graded set of clinical symptoms that may or may not include loss of consciousness Symptoms usually short-lived and resolve spontaneously but in some cases can be prolonged Consensus statement on concussion in sport.

SCAT3: locker room or clinic Consensus statement on concussion in sport. Br J Sports Med. 2013 Apr;47(5):250-8 Concussion treatment Cognitive rest Physical rest No same day return to play Medication Avoid aspirin and ibuprofen Tylenol OK Avoid alcohol Avoid driving 3

Recovery time after sport concussion in high school athletes 50% in 1 week 83% in 3 weeks 17% longer than 3 weeks High school athletes take longer to recover based on neuropsychological testing compared to college athletes (Field et al, J Pediatr, 2003.) (Collins MW et al, Neurosurgery, 2006.) Prolonged symptoms: > 4 weeks. Consider neurology or neuropsychology consult. Asymptomatic Return to work/play Normal neurologic exam (SCAT3) Cognitive Balance Computerized neuropsychological testing Guskiewitcz in SCAT2 Clin J Sports Med. July 2010. Return to school/work Increasing attention to need for cognitive rest in concussion First return to school/work, then return to play School/work note requesting accommodations Gradual return to school/work as symptoms allow No school. Rest. Return to school progression 15 min cognitive activity at a time 30 min schoolwork at a time until can do 1-2 hours Return to ½ day of school Return to full day of school http://www.chop.edu/service/concussion-care-for-kids/returning-to-school.html 4

Radiographs: 2 keys to ordering knee xrays 1. Minimum 2 views of every joint (AP and lateral) 1. Knee has 2 articulations: want 2 views of each 1. Patella femur 2. Femur- tibia 2. Weight-bearing views to evaluate for arthritis Arthritis is not painful if it s not weight-bearing. Reproduce the painful situation to see the degree of cartilage loss. Flexion weight-bearing PA view, aka Notch view Patient standing, knees bent to 45 degrees. Evaluate medial and lateral compartments for OA Fractures Lateral of the affected side Merchant view = axial view of the patella Patellofemoral compartment Patellar fracture 7

Action plan: Exercise is Medicine 1. Identify potential health benefits of exercise. 2. Is the patient healthy enough to begin exercise? 3. Assess patient s stage of change. 1. Precontemplation 2. Contemplation 3. Preparation 4. Action and maintenance 4. Write the exercise prescription. http://exerciseismedicine.org/documents/hcpactionguide.pdf. Accessed 11/6/11. Should we spend clinic time on this? Small benefit of providing medium or highintensity counseling on diet and exercise to healthy patients Healthy = no diabetes, heart disease, hypertension, hyperlipidemia Spend clinic time Counseling patients who are less healthy Counseling patients are motivated to change Using community resources to motivate change Moyer VA; U.S. Preventive Services Task Force.
