Dr. Liavaag discusses shoulder immobilization following primary shoulder dislocation.
188 patients with primary traumatic anterior shoulder dislocation were randomized to be managed by immobilization in either internal rotation or 15° of external rotation for a period of 3 weeks. The 2-year follow up concludes that the re-dislocation rates were similar in both the treatment groups.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?
Sì = 1
Incerto = 0,5
Non rilevante = 0
No = 0

L'Indice di Fragilità è uno strumento che aiuta l'interpretazione dei risultati significativi, fornendo una misura della forza di un risultato. L'Indice di Fragilità rappresenta il numero di eventi consecutivi che devono essere aggiunti a un risultato dicotomico per rendere il risultato non più significativo. Un numero piccolo rappresenta un risultato più debole, mentre un numero grande rappresenta un risultato più forte.
Perché questo studio era necessario ora?
There is a high risk of recurrence following a primary traumatic anterior shoulder dislocation, especially in the younger population. There have been several variable suggestions as to the best management. The orthopedic community is divided over the usefulness of the immobilization in external rotation. The study provides much needed evidence to determine best management.
Qual era la domanda di ricerca principale?
Does immobilization in external rotation provides any additional benefit to the future risk of recurrence, compared to standard immobilization in internal rotation?
- recurrence rate of 30.8% with immobilization in external rotation vs. 27.1% in internal rotation
- mean time to recurrence 10.5 months in External rotation group vs. 11.6 months in Internal Rotation group.
- median WOSI Score of 238 in external rotation vs. 375 in internal rotation group
Che cosa devo ricordare di più?
External rotation immobilizers are not beneficial to reduce the risk of future shoulder dislocation.
Come influenzerà l'assistenza ai miei pazienti?
Although this study finds that external rotation immobilizers are not beneficial, the sample size may be too small for definitive conclusions.
