Epub 2013 Mar 22109 patients with traumatic shoulder dislocation were randomized to determine the effect of a shoulder motion restriction band on recurrence rates. Following reduction and immobilization in external rotation for 3 weeks, participants received either 6- or 3-week use of the restriction band, or no band use. Assessments were conducted for a minimum of 2 years following reduction, and no difference between groups was observed for overall recurrence of shoulder dislocation, even when patients were stratified by age.

Der Fragilitätsindex ist ein Instrument, das bei der Interpretation signifikanter Ergebnisse hilft und ein Maß für die Stärke eines Ergebnisses liefert. Der Fragilitätsindex gibt die Anzahl der aufeinanderfolgenden Ereignisse an, die zu einem dichotomen Ergebnis hinzugefügt werden müssen, damit das Ergebnis nicht mehr signifikant ist. Eine kleine Zahl steht für ein schwächeres Ergebnis und eine große Zahl für ein stärkeres Ergebnis.
Warum wurde diese Studie jetzt benötigt?
Traumatic shoulder dislocations, which boast one of the highest recurrence rates, are almost invariably associated with a Bankart lesion. Immobilization in 10 degrees external rotation for 3 weeks following the injury has been suggested as an appropriate protocol for healing of the lesion, however the true length of time required for healing is still unknown. Furthermore, it is imperative that the inferior glenohumeral ligament-labrum (IGHL) complex, in which healing is still ongoing following 3 weeks of immobilization, not be stretched. Maximum tension on the IGHL occurs with the arm at 90 degrees abduction and maximum external rotation, which may be protected by the use of a motion restriction band.
Was war die wichtigste Forschungsfrage?
Following 3-week immobilization at 10-15 degrees external rotation after traumatic shoulder dislocation, what was the effect of 6- or 3-week use of a shoulder motion restriction band compared to no band use on recurrent shoulder dislocation within 2 years?
Was waren die wichtigsten Ergebnisse?
- Recurrent dislocation occurred in 8/29 0-week patients (28%), 10/30 3-week patients (33%), and 10/31 6-week patients (32%) (P=0.88). 20 of the shoulders with recurrent dislocation (71%) were due to sports injuries.
- In the subgroup analysis of patients 30 years of age or younger, recurrence rates were 7/15 in the 0-week group (47%), 9/21 in the 3-week group (43%), and 8/24 in the 6-week group (33%) (P=0.67).
- In the subgroup analysis of patients over the age of 30, recurrence rates were 1/14 in the 0-week group (7%), 1/9 in the 3-week group (11%), and 2/7 in the 6-week group (29%) (P=0.43).
- Rates of return to sports was 18/21 0-week patients (86%), 16/22 3-week patients (73%), and 21/24 6-week patients (88%) (P=0.39). Return to preinjury level was 13/21 in the 0-week group (62%), 12/22 in the 3-week group (55%), 14/24 in the 6-week group (58%) (P=0.89).
- Return to contact sports was 1/2 in the 0-week group (50%), 4/7 in the 3-week group (57%), and 2/2 in the 6-week group (100%) (P=0.35). Return to noncontact sports was 9/16 in the 0-week group (56%), 6/13 in the 3-week group (46%), and 12/22 in the 6-week group (55%) (P=0.85).
- There was no significant difference between groups in rates of compliance to immobilizer use (P=0.11), restriction band use (P=0.28), or both (P=0.54).
Was sollte ich mir besonders merken?
There was no difference in recurrence rates of shoulder dislocation observed with the use of a shoulder motion restriction band (for 3 and 6 weeks) compared to no use after 3 weeks of immobilization in external rotation following primary traumatic shoulder dislocation.
Wie wird sich dies auf die Behandlung meiner Patienten auswirken?
These results do not suggest there is an advantageous effect of shoulder motion restriction bands with respect to recurrence of dislocation. Further investigation may consider the effect of restriction band use on clinical outcome and shoulder range of motion.
