1 Learning curve in 20 years of brace treatment F. Landauer University Clinic of Orthopedics (PMU) Salzburg General Hospital Muellner Hauptstr. 48, 5020 Salzburg Austria

2 Purpose Objectification of his own learning curve in brace treatment Design: Retrospective case study of adolescent scolosis Methods: I compared a group of 100 outpatients treated 20 years ago with a further group of 100 outpatients treated recently. The brace indication depends on the SOSORT-criteria. Cobb angle was measured before treatment, primary correction and follow up >1 years after weaning of the brace. Compliance was estimated by our own compliance score (Lit. 1). All braces are made by one orthotist.

3 First presentation Cobb angle Range: Risser < II New facts Schoolscreening becomes better. But there are some poor results. Paracelsus Medizinische Privatuniversität / SOSORT-Scientific-2014-Wiesbaden / 20 years of experience / F. Landauer 3

4 First presentation Cobb angle Range: Risser < II New facts Pretreatement 8% without any orthopaedic examiation. Refuse bracing 10% Paracelsus Medizinische Privatuniversität / SOSORT-Scientific-2014-Wiesbaden / 20 years of experience / F. Landauer 4

5 First presentation Cobb angle Range: Risser < II n- 84 New facts Non idiopathic 6% MRI is available A generous indication of MRI rises the number of non idiopathic scoliosis Paracelsus Medizinische Privatuniversität / SOSORT-Scientific-2014-Wiesbaden / 20 years of experience / F. Landauer 5

6 Primary correction Cobb angle Primary correction becomes better Facts 20 to 16 inaccuracy of measurement Not significant Paracelsus Medizinische Privatuniversität / SOSORT-Scientific-2014-Wiesbaden / 20 years of experience / F. Landauer 6

7 Primary correction Primary correction becomes better % of correction New facts Selection Handcraft? Differentiation? Cobb angle at brace indication Influenced by the indication: idiopathic / non idiopathic scoliosis Paracelsus Medizinische Privatuniversität / SOSORT-Scientific-2014-Wiesbaden / 20 years of experience / F. Landauer 7

8 Bracing Brace wearing-time per day: Requirement as fulltime bracing : 20 years ago 23 hours current max. 20 hours My personal experience and rules: 20 hours is realistic (measured with a sensor) scoliosis remains flexible 4 hours for sports and free movement Paracelsus Medizinische Privatuniversität / SOSORT-Scientific-2014-Wiesbaden / 20 years of experience / F. Landauer 8

9 Compliance GOOD compliance interview of patients regular examination in the OPD (clinical control every three month s and x-ray every six month s) signs of brace wear skin reaction The compliance is unchanged over 20 years of treatment The arrangement are modulatd by the patients: But now: approximately 10% refuse bracing or don t accept fulltime bracing Patient communicate their dicission This data are still without sensor-measurement BAD compliance irregular bracing therapy break (>three month s) irregular control

10 Who is responsible for? Medical doctor: Indication, diagnostics, control, compliance, etc Physiotherapist: Quality of the training program, compliance, etc Orthotist: Relatives: Patient: Quality of the brace, compliance Well beeing, compliance Compliance Compliance is the connecting buzzle. Communication is the important factor for success! Paracelsus Medizinische Privatuniversität / SOSORT-Lecture-2014-Wiesbaden / Factors success and failure / F. Landauer 10

11 Follow up Cobb angle Follow up: inaccuracy of measurement n- 86 Paracelsus Medizinische Privatuniversität / SOSORT-Scientific-2014-Wiesbaden / 20 years of experience / F. Landauer 11

12 Follow up Cobb angle Follow up: inaccuracy of measurement n- 86 Progression > 50 : 12% 3% Influenced by: Diagnostics Bracing Paracelsus Medizinische Privatuniversität / SOSORT-Scientific-2014-Wiesbaden / 20 years of experience / F. Landauer 12

13 Summary Now scoliosis is diagnosed earlier, but the number of unskilled pretreatment and rejection of treatment increases. Improvement of diagnostic: lowers the number of idiopathic scoliosis (MRI, genetics, etc.). Bracing becomes more effective: in primary correction and at follow up despite of a lower wearing time per day. Compliance: We could not influence compliance significantly. We adapted bracing to a realistic treatment concept. Paracelsus Medizinische Privatuniversität / SOSORT-Scientific-2014-Wiesbaden / 20 years of experience / F. Landauer 13

14 Conclusion Patients increasingly influence therapeutic regime. Part time bracing becomes the main option in outpatient treatment (<20 hours). There is still potential to improve brace-management. In outpatient treatment compliance of the staff seems to be a problem. To many different statements! An experienced orthopedic technician leads to a good standard, but it lacks on comparison and competition. The endresult did not become much better, but with less treatment! Consequences: My peronal focus changed from the bracing to the diagnostics. I have to tighten the bracing. I have to tighten the organization of the outpatient management.
