Closed reduction; screw fixation

1. General considerations


The physeal fragment is fixed with a retrograde intramedullary screw. This risks growth arrest and is only recommended in adolescents.

Open reduction is necessary if it is not possible to obtain or maintain adequate reduction by closed manipulation.

Treatment goals

The main treatment goals are:

  • Stabilize the fracture
  • Minimize further physeal injury

2. Instruments and implants

Appropriately sized cannulated or noncannulated screws can be used.

The following equipment is used:

  • Screw set
  • Drill
  • Image intensifier
Drill, cannulated, partially threaded screw, and guide wire

3. Patient preparation

Place the patient in a supine position on a radiolucent table with a block under the heel.

4. Reduction

Apply longitudinal traction through the foot.

If this is not successful, consider open reduction.

5. Fixation


Perform a stab incision the tip of the fibula.

Spread the underlying soft tissues with a clamp and place a soft-tissue protector down to the bone.

Assessment of reduction

Confirm reduction, fracture stability, and screw placement with an image intensifier.

6. Immobilization

A molded below-knee cast or fixed ankle boot is recommended for a period of 2–6 weeks as the strength of fixation may not provide sufficient stability for unrestricted weight bearing.

7. Aftercare

Immediate postoperative care

Weight-bearing is encouraged.

Older children may be able to use crutches or a walker.

Younger children may require a period of bed rest followed by mobilization in a wheelchair.

Pain control

Patients tend to be more comfortable if the limb is splinted.

Routine pain medication is prescribed for 3–5 days after surgery.

Neurovascular examination

The patient should be examined frequently to exclude neurovascular compromise or evolving compartment syndrome.

Discharge care

Discharge follows local practice and is usually possible within 48 hours.


The first clinical and radiological follow-up is usually undertaken 5–7 days after surgery to check the wound and confirm that reduction has been maintained.

Cast removal

A cast or boot can be removed 2–6 weeks after injury.


After cast removal, graduated weight-bearing is usually possible.

Patients are encouraged to start range-of-motion exercises. Physiotherapy supervision may be required in some cases but is not mandatory.

Sports and activities that involve running and jumping are not recommended until full recovery of local symptoms.

Implant removal

Implant removal is not mandatory and requires a risk-benefit discussion with patient and carers.
