  • Pulled Elbow Reduction
  • Annular Ligament Reduction

Introduction

General

  • This page reviews reduction techniques for so-called Nursemaids Elbow
    • This is also known as subluxation of the annular ligament

Anatomy of the Annular Ligament

  • Strong, circular ligamentous band that anchors the Radius to the radial notch of the Ulna
  • Stabilizes the proximal radioulnar joint while allowing rotation pronation/supination

Indications

Contraindications

  • Other diagnosis more likely

Procedure

Hyperpronation Technique
Supination Flexion Technique

Equipment

  • No equipment needed

Preparation

  • Child should be present and relaxed
  • Parents can help
    • Ideally, child seated in parents lap facing examiner

Hyperpronation Technique

  • Preferred and first line maneuver
  • Favored over Supination & Flexion[3]
    • Significantly lower first-attempt failure rates (9.4%) compared to supination-flexion (25%)[4]
  • Description[5]
    • Stabilize the child's elbow at 90° of flexion with one hand while
    • Grasp the child's hand in a handshake grip with the other
    • Apply firm hyperpronation (rotating the forearm inward, palm facing downward)
    • While maintaining gentle pressure over the radial head with the thumb
    • A palpable or audible click over the radial head typically confirms successful reduction

Supination & Flexion Technique

  • Description
    • Stabilize the elbow with one hand while grasping the child's wrist with the other
    • Apply firm supination (rotating the forearm outward, palm facing upward)
    • Then fully flex the elbow so the wrist is directed toward the ipsilateral shoulder
    • While maintaining thumb pressure over the radial head
  • First-attempt success rate is lower than hyperpronation at 68–77%[6]

Aftercare

  • Post reduction
    • Child typically has full range of motion within 10-30 minutes
    • Will begin spontaneously moving affected arm
    • Can challenge with item of interest (i.e. bottle, popsicle, etc)
  • If unsuccessful reduction, recommend obtain radiographs and consider alternative diagnosis

Complications

  • Alternative diagnosis
  • Inability to reduce
