Jammed finger in children: volar plate injury

A swollen finger after a ball injury may involve the volar plate, a fracture or a dislocation. Assessment guides protection and movement.

Updated: October 2026·Medically reviewed by Dr. Daniele Priano

A ball striking the finger can bend it backwards and injure the volar plate, the structure on the palm side that limits joint overextension. The joint in the middle of the finger, the proximal interphalangeal (PIP) joint, is often involved; a small piece of bone may also be pulled away.

“Jammed finger” describes an injury, not a diagnosis. Other fractures, a tendon injury or a dislocation may require different treatment.

Alignment and stability come first

Examination assesses pain, movement, sensation and finger position. X-rays look for bone fragments and joint misalignment. An X-ray without a fracture does not exclude a soft-tissue injury.

Protection needs to allow the right movement

A stable, aligned joint often does not need surgery. The clinician chooses protection that limits excessive extension, sometimes with strapping to the neighbouring finger, and explains permitted movements. Keeping it still longer than necessary is unhelpful, but forcing it to “unlock” is unsafe too.

Swelling and stiffness may outlast the initial pain. Worsening movement, a finger that stays bent or recurrent deformity needs reassessment. Return to ball sports, contact activities and activities with a risk of falling depends on healing, stability and function. The volar plate surgery page explains when protection alone is insufficient.

Assessment and treatment

When to seek evaluation

  • Pain, swelling or difficulty moving the finger after injury
  • Deformity, an open wound, pallor, coldness or loss of sensation needs urgent assessment; do not straighten the finger yourself
  • Worsening movement or persistent deformity during recovery

What is evaluated

  • Alignment, rotation, movement and sensation
  • Fractures and joint congruence on X-rays
  • Stability after initial treatment and the need for follow-up

Treatment options

  • Protection and guided movement for stable injuries
  • Follow-up and hand therapy when indicated
  • Surgical assessment for instability, an unresolved dislocation or an inadequately aligned joint fracture

When Surgery Is Needed

Surgery is considered for selected injuries where a stable, aligned joint cannot be maintained.
