Study summary

The aim of this study is to investigate whether short-arm fiberglass cast (SAC) immobilization provides fracture stabilization comparable to that of long-arm cast (LAC) treatment of displaced and non-displaced distal Salter Harris I/II forearm fractures in paediatric patients.

Read the detailed description

The patients are allocated randomly into the two groups(short-arm cast, long-arm cast). After confirming study participation, patients draw a sealed envelope enclosing a numbered card, which assignes them to one group or other. After choosing the envelope, neither the ED staff nor the parents and their childrenare blinded for the treatment groups. However, the data are going to be analyzed under blinded conditions

Inclusion criteria

  • Salter Harris I or II fracture of the distal radius or a forearm fracture

Exclusion criteria

Exclusion Criteria:

  • open/instable/intraarticular fracture
  • age \<4 years or > 16years
  • no
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    short-arm fiberglass cast

    salter harris fractures of the distal radius/forearm in children are usually treated with fiberglass long-arm casts. The investigators were able to demonstrate that in distal metaphyseal forearm fracture, treatment with a short-arm cast is not inferior to a long-arm cast. Patients are going to receive a short-arm cast for fracture treatment.

    Device: short-arm fiberglass cast

  • Active comparator
    long-arm fiberglass cast

    salter harris fractures of the distal radius/forearm in children are usually treated with a fiberglass long-arm cast. Patients are going to receive a long-arm cast for fracture treatment.

    Device: long-arm fiberglass cast

What researchers measure

Primary outcomes

  1. Rate of fracture displacement

    difference in fracture angulation values either at pre-treatment or during follow-up between the two groups (short-arm cast; long-arm cast)

    Time frame: in the first four weeks after trauma
