Pediatric proximal forearm

back to Pediatric overview


Supine position

Preoperative preparation

The following are essential for successful surgery:

  • Patient information
  • Operating room personnel (ORP) information/instruction
  • Surgical planning

Patient information

Before treatment discuss the following information with the patient/parents/carers:

  • Nature of the injury
  • The chosen treatment and why a particular treatment is selected
  • Alternative treatments
  • General operative risks
  • Expected healing time
  • Functional recovery
  • Implant removal

Information for operating room personnel

Operating room personnel (ORP) need to know and confirm:

  • Consent form, completed and signed
  • Site and side of fracture
  • Type of operation planned
  • Surgical approach
  • Operative site has been marked by the surgeon
  • Condition of soft tissues
  • Equipment/implants needed
  • Patient positioning
  • Duration of operation
  • Positioning of image intensifier
  • Antibiotic prophylaxis
  • Comorbidities, including allergies

Surgical planning

The surgeon should ensure that:

  • Relevant x-rays and other images are available in the OR.
  • Required instruments and implants are accessible and ready.
  • Tourniquet is available (a sterile tourniquet makes draping more straightforward).
  • Image intensification is available.
  • Intraoperative x-ray documentation should be undertaken, with clear AP and lateral views, before applying any plaster cast.
  • There is a clear, step-by-step plan of the operation, including backup plans.


  • General anesthesia
  • Local nerve block
  • Combination of nerve block and light general anesthesia
  • Prophylactic antibiotics (see local microbiological protocols)

Supine position with an arm table enlarge

Patient positioning

Position the patient supine and place the forearm on an arm table.

Supine position for small children enlarge

For small children, it may be necessary to rest the shoulder on the arm table to allow unimpeded imaging.

This may require gentle lateral flexion of the neck and trunk with appropriate padding and attention to pressure areas.

By abducting the shoulder, it is possible for the surgeon and the assistant to sit on opposite sides of the hand table.

Supine position with arm over the chest enlarge

The elbow may be flexed and held by an assistant. This setup is useful for access to the olecranon.

The use of the image intensifier requires the arm to be brought into a lateral position.

Supine position - C-arm positioning enlarge

C-arm positioning

There are two possible positions for the C-arm:

  • Parallel to the operating table
  • Perpendicular to the operating table

Supine position - Skin disinfecting and draping enlarge

Skin disinfecting and draping

With an assistant holding the arm, disinfect the entire arm down to the fingertips.

Drape the hand in a glove or leave it free.

Drape the arm up to the shoulder.

Preparing the whole arm allows application of a sterile tourniquet if required.

Supine position - OR set-up enlarge

OR set-up

The optimal position of the surgeon is defined by anatomical requirements of the fixation and may need to be changed during surgery.

The position of the screen should allow a direct view for the surgeon.

Supine position - OR set-up enlarge

The setup with the arm over the chest is useful for access to the olecranon.
