Distal Radius Fractures

Edit

Edited by Nattaly Greene, David Evans - 7/1/2021

Descriptor

  • Incomplete (Buckle) and Complete (Nondisplaced, displaced, Bayonet apposition)
  • Apex dorsal vs. volar angulation

Exam Pearls

  • Pain, swelling, and tenderness localized to the wrist. Gross deformity may or may not be present. Assess for puncture wounds
  • Evaluate active and passive range of motion of the forearm, wrist, and hand
  • In non verbal children; assess for decreased spontaneous movement of the extremity

Workup

Radiographs: AP/Lateral of wrist and forearm. Include elbow films if any tenderness at the elbow. Other imaging: May consider a CT scan to evaluate intra articular fracture

Labs: None

Other: Classification depending on location of fracture in relation to distal physis- Salter Harris classification
Fracture with dislocation/associated injuries - Galeazzi(distal ⅓ radius with associated DRUJ injury)

Management

Need for acute intervention: Yes, immobilization +/- reduction

Immobilization without reduction
- Unicortical or bicortical fractures with <10 degrees of angulation
- Torus/buckle fracture - may use prefabricated removable wrist splint

Immobilization with reduction
- Closed reduction under conscious sedation followed by casting
- Fractures with >10-20 degrees of angulation
- Salter Harris I or II with unacceptable angulation

Reduction technique: Recreate and exaggerate deformity, pull traction maintaining deformity, and realign using tension on the intact periosteum

Acceptable Angulation Parameters

Weight-bearing and range of motion: Nonweightbearing

Type of immobilization: Long arm bivalved cast with good three point mold

Admission or discharge status: Discharge with one week follow up with repeat wrist Xrays. Admit if open fracture or any neruovascular compromise

Anticoagulation: None

Antibiotics: None unless open fracture

Surgical Indications

Absolute: Open fracture which will need formal irrigation and debridement
