Reduction of anterior shoulder dislocation: Milch technique results in high success rate .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(6):121 J Shoulder Elbow Surg. 2012 Nov;21(11):1443-9. doi: 10.1016/j.jse.2012.01.004. Epub 2012 Apr 18.60 patients with anterior shoulder dislocation requiring nonsedated reduction were randomized to undergo the Milch technique or Stimson technique. The results of the study indicate that the success rate and time to achieve reduction without sedation were superior for the patients that underwent the Milch technique when compared with the patients that underwent the Stimson technique. The Milch technique becomes a reasonable management alternative to reduction with sedation when early implementation of reduction, low pain levels at presentation, and oral pain medication are successfully combined.
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)?

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?
The shoulder can be reduced using simple techniques in the emergency department. Many reduction techniques exist, but the optimal treatment has yet to be determined. The optimal technique should be one that is quick and easy to perform, pain free, require little medication, cause no additional injury to the shoulder, and reduce the burden of treatment costs. This study aimed to determine whether there is a difference in success rate between the Milch technique and Stimson technique among patients with anterior shoulder dislocation.
Qual era la domanda di ricerca principale?
Is there a difference in success rate between the Milch technique and Stimson technique among patients with anterior shoulder dislocation?
- The first reduction attempt was successful in 29 of the 35 patients (82.8%) that underwent the Milch technique and 7 of the 25 patients (28%) that underwent the Stimson technique (p<0.001).
- The reason for failure in the first attempt for the 6 out of 35 patients (17.2%) that underwent the Milch technique was due to pain and the need for sedation. The leading cause of failure in the first attempt for the 18 out of 25 patients (72%) that underwent the Stimson technique was request to discontinue the treatment due to the inconvenience of the prone position.
- The mean reduction time for the patients that underwent the Milch technique was 4.68 minutes, whereas the mean reduction time was 8.84 minutes for the patients that underwent the Stimson technique (p<0.007).
- Pain was not significantly different between the patients that underwent the Milch technique and the patients that underwent the Stimson technique.
- The 3 factors that affect success rate were reduction technique, the time interval between dislocation and first reduction attempt, and the level of pain on admission to the emergency department with an odds ratio of 0.037 in favor of the Milch technique, 7.16 in favor of short time, and 1.81 in favor of low levels of pain.
Che cosa devo ricordare di più?
The data suggests that the patients that underwent the Milch technique for reduction of an anterior shoulder dislocation achieved a significantly higher first success rate and a significantly lower mean reduction time than the patients that underwent the Stimson technique.
Come influenzerà l'assistenza ai miei pazienti?
The study suggests that the Milch technique may be a reasonable technique for reduction of an anterior shoulder dislocation without sedation. Early implementation of reduction, experiencing low pain levels at presentation, and oral pain medication are positive predictors of a successful reduction. Further research using larger sample sizes is required to determine the external validity of the results presented in this study. Future studies need also to evaluate differences in both techniques with intraarticular analgesia.
