Ultrasound imaging successfully located a 2-cm bamboo splinter in a patient's wrist, resolving persistent pain after initial tests were inconclusive. This case highlights ultrasound's value in diagnosing retained foreign bodies.

Area of Science:

  • Medical Imaging
  • Orthopedics
  • Emergency Medicine

Background:

  • Retained foreign bodies can cause persistent pain and complications.
  • Initial diagnostic workup including clinical examination and X-ray may fail to detect certain foreign materials.
  • Bamboo splinters pose a diagnostic challenge due to their composition and potential for subtle imaging findings.

Purpose of the Study:

  • To demonstrate the utility of ultrasound in identifying a retained bamboo splinter.
  • To illustrate the successful localization of a foreign body missed by conventional methods.
  • To highlight ultrasound as a valuable tool for persistent musculoskeletal symptoms.

Main Methods:

  • High-resolution ultrasound was employed for targeted imaging of the wrist.

  • The hyperechoic nature of the bamboo splinter was identified.
  • Ultrasound guided the precise localization of the foreign body.

    • Main Results:

    • A 2-cm hyperechoic bamboo splinter was accurately identified and localized in the wrist.
    • The splinter was detected 1 month after the initial injury, despite prior negative workup.
    • Successful diagnosis led to appropriate management of the patient's persistent symptoms.

    Conclusions:

    • Ultrasound is a sensitive and effective modality for detecting retained foreign bodies, particularly those missed by X-ray.
    • This case underscores the importance of considering advanced imaging when clinical suspicion for a foreign body persists.
    • Prompt and accurate diagnosis using ultrasound can lead to timely intervention and symptom resolution.
