Is casting greenstick fractures in children an overtreatment ?
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(2):127 J Trauma. 2010 Feb;68(2):425-8.92 children (age range 4 to 13 yr) with an impacted greenstick fracture of the distal radius or ulna were randomized to be managed by either casting or a soft bandage therapy. Follow-up was conducted at 1, 4, and 6 weeks after randomization. Soft-bandage therapy produced greater pain at the start of the treatment than cast therapy, but it allowed for a faster recovery in wrist function and reduced overall discomfort.
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)?

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?
Distal forearm fractures make up 20% of all fractures in children. Currently, casting is regarded as the standard management for greenstick fractures of the distal forearm in children. However, cast therapy produces discomfort, functional loss, and the possibility of developing dystrophy. This study assessed if the casting had an advantage over conservative management using a soft bandage in pediatric green stick fractures.
Was war die wichtigste Forschungsfrage?
In children with impacted greenstick fractures, what are the relative risks and advantages of using soft bandage therapy compared to cast therapy, in prevention of secondary displacement of the fracture, assessed over 6 weeks following casting?
- At 4 weeks, patients in the soft-bandage therapy group had a significantly better wrist function than the cast therapy group with a median ROM of 154 degree vs. 121 degree (p<0.001)
- There was no statistically significant difference in the wrist functions between the two groups at 6 weeks follow-up (p=0.49)
- At 1 week follow-up, the mean VAS in the soft-bandage therapy group (26+/-19mm) was significantly higher than the cast therapy group (20+/-16mm; p=0.03). When the patients in the soft-bandage therapy group, who were unable to regulate their activities, were excluded from the analysis at 1 week, the mean VAS was not significantly different from the cast therapy group (p=0.17). No differences in the VAS at 4 and 6 week evaluation between groups (p=0.96 and 0.70, respectively).
- At 3 weeks follow-up, patients in the cast group reported itchiness 290 times, compared to only 140 times in the soft-bandage therapy group (p<0.001). There was no statistically significant difference in other areas of discomfort.
Was sollte ich mir besonders merken?
Compared to the standard treatment for impacted greenstick fractures of the distal forearm, soft-bandage therapy was less effective in preventing pain occurrence in the beginning of the treatment. However, patients who received soft-bandage therapy recovered their wrist functions at an earlier time and also experienced less overall discomfort during the healing process.
Wie wird sich dies auf die Behandlung meiner Patienten auswirken?
In children with impacted greenstick fractures, a switch from current standard of care to bandage therapy can allow them to recover wrist function earlier, experience less discomfort, and return to normal activity sooner, without any risk of secondary displacement. Additional studies should be conducted to complement the evidence of bandage versus cast therapy in the management of greenstick fractures.
