Match up the following Cobb angle degrees with the appropriate treatment plan. Question 9 options: Cobb angle 11 to 19 degrees Cobb angle 20 to 29 degrees Cobb angle 40 to 49 degrees Cobb angle 30 to 39 degrees Cobb angle 10 degrees or less 1. Observation with clinical follow up every six to nine months until skeletal maturity. 2. Observation with clinical follow up and radiographically every five to six months until skeletal maturity. Exercises to strengthen the back. Bracing may be indicated if the Cobb angle increases by 5 over a three- to six-month period. 3. Bracing for treatment in these patients. Monitoring and follow up clinically with X-rays every six months until skeletal maturity. Surgical correction may be indicated if the curve progresses to 50 despite bracing or if the curve progresses rapidly. 4. Treatment is bracing or surgery for patients with substantial growth remaining. Monitoring and follow up clinically with X-rays every six months until skeletal maturity. Surgical correction may be indicated if the curve progresses to 50 despite bracing. 5. No follow-up other than routine screening at well-child visits is needed
