Introduction

Soft tissue foreign bodies are frequently a result of penetrating or abrasive trauma and can result in substantial patient discomfort, deformity, complications involving localized and systemic infection, and further trauma during removal. For information on trauma of all kinds, visit Medscape's Trauma Resource Center.

In most cases, foreign bodies are the result of accidental trauma directly to the soft tissue area of interest; however, other mechanisms such as unwitnessed syncope, potential elder or child abuse, or assault by other persons or personal harm should also be considered.1,2 Patients who present with localized pain after trauma should be questioned about the specific nature of the trauma and examined for an obvious or occult foreign body. Straightforward cases that involve solid, formed, metallic objects obvious on examination, such as nails, staples, and needles, may require less history than the case of an individual with localized pain and foreign body sensation who is unaware of the exact time of onset, sequence of events leading to symptoms, or potential foreign bodies.3

The delayed presentation of foreign bodies can masquerade as a localized cellulitis, abscess, or regional inflammatory response involving edema or redness. A history of recurrent localized infections should prompt a search for an occult foreign body and should include a discussion of recent or remote trauma that could have resulted in the deposition of a foreign body.4,5,6,7 Additional cases involve soft tissue foreign bodies from splinters to bullet fragments found subcutaneously years after the trauma (eg, a gunshot wound that occurred years prior to presentation).8,9,10,6,5,11,12,13

A close visual inspection of the area of localized pain is the first step to determine whether a foreign body is immediately visible. Additionally, note the region of redness or inflammatory response or associated edema.4 Obvious punctures through skin should not distract from less obvious skin areas where skin may be tenting, edematous, or otherwise appear abnormal, or may be tender to palpation as a result of the presence of a foreign body. If a foreign body is palpable, valuable information regarding the location, positioning, and orientation as well as the flexibility and mobility of the foreign body may be available.

Occult foreign bodies are the cause for localized or systemic inflammatory or infectious responses that require a significant diagnostic workup for localization, identification, and treatment.5,3 Secondary symptoms can often provide the clinician with the evidence that may initiate a foreign body search.14 A detailed neurologic and vascular examination should be performed to investigate for distal neurovascular compromise.14  A functional assessment of movement helps to refine the potential musculoskeletal damage that may have occurred during foreign body deposition. This is important information to obtain prior to any attempt to remove a foreign body.

Soft tissue infection caused by foreign bodies can result in additional emergency department (ED) and primary care visits; this is a frequent reason for physician malpractice litigation. Wound care is the subject of 5-20% of lawsuit claims against emergency physicians, and claims about wound care result in 3-11% of award payouts.15 For more information on wound care, visit Medscape's Wound Management Resource Center.

Indications

Indications for removal of a foreign body include the following:14

  • Neurovascular compromise
  • Evidence of infection
  • Cosmetic deformity
  • Functional impairment
  • Chronic pain
  • Patient request

The potential for complications due to the process of removal must be considered. Such complications may include the following:7

  • Enlarging the wound or creating an additional wound
  • Blunt or sharp dissection of nearby tissue
  • Chemical or electrocautery required for hemostasis
  • Additional infection risk for soft tissue that may require cosmetic repair with sutures following removal of the foreign body

Contraindications

Contraindications related to foreign body removal involve the following:3,6

  • Deep embedding
  • Compromise of the integrity of nearby neurovascular or other structures during the retrieval process
  • Poor or inadequate information on the position of the foreign body, leading to further exploration in the operating room
  • Inadequate hemostasis or the potential for severe bleeding, especially if the patient has a clotting or bleeding disorder
  • Cosmetic deformity related to the process of removal

Anesthesia

Local anesthesia provides the mainstay in pain control for foreign body removal.

  • Lidocaine (with or without epinephrine), bupivacaine, and even topical lidocaine-epinephrine-tetracaine (LET) solutions or creams are useful in creating anesthesia at the site of exploration or removal.16,3 For more information, see eMedicine topics Local Anesthetic Agents, Infiltrative Administration and Anesthesia, Topical.
  • The field block and nerve distribution blocks at the sites of the wrist and ankle and at the bases of fingers or toes are useful anesthetic tools prior to a more extensive invasive evaluation or removal attempt.
  • Removal of a nail through the hand or foot is aided by blocking the relevant nerve distributions prior to an attempt.6,10
  • Field blocks that surround the site of a splinter or staple entrance are essential for pain management during the procedure.
  • A digital nerve block aids immensely the removal of a fish hook through a finger and also helps in postprocedure pain management.17

For detailed descriptions of various nerve blocks, please visit the Anesthetic and Analgesic Techniques section of eMedicine’s Clinical Procedures journal.

Equipment

  • Imaging modalities and localizing skin markers for the detection of foreign bodies (described in Imaging section below)
  • A surgical incision and drainage kit or a suture kit that contains the following:
    • Forceps
    • Kelly clamp
    • Chlorhexidine or other field sterilization cleansers
    • Drapes
    • Scalpel, No. 11
  • Needle, small gauge
  • Syringe, 10 mL
  • Electro/chemical cautery tools16

Positioning

  • Patient positioning is important to achieve several goals.
    • To dissipate force if substantial force is required
    • Comfort during extended removal period to relieve the patient of the burden of supporting a limb or other body part (Additional personnel or hardware may be required.)
    • Adequate visualization, inspection, and unhurried removal
    • Protection against trauma from a vasovagal episode
    • Protection of neurovascular structures in close proximity to the foreign body
  • Various items may be helpful for proper positioning.
    • Padding
    • Temporary restraints
    • Pillows
  • Adequate lighting, a seated position, and appropriate table and patient height can optimize the physician’s procedural outcome, as well.16,3

Technique

No single technique is best for the removal of soft tissue foreign bodies.18,19,2,20,21,22,17,23,23,24,25,26 The following principles, however, can guide one’s choice of approach:

  1. Obtain informed consent for the potential of future infection, pain, and disability.
  2. Obtain necessary imaging information. If possible, use ultrasonography or fluoroscopy during removal.
  3. Perform a detailed neurovascular examination.
  4. Administer an adequate nerve block.
  5. Use incisions, blunt dissection, and other methods that cause tissue deformation judiciously.
  6. Use good surgical site bleeding control (eg, electrocautery, stitching, lidocaine with epinephrine) to create a bloodless field.
  7. Provide detailed follow-up care instructions.
  8. Consider antibiotic prophylaxis for excessively dirty wounds or in members of populations at risk for infection.
  9. Update the patient’s tetanus status, as needed.
An example of a technique involved in the removal of a fish hook with a barbed point buried in the finger pad is as follows:17
  1. Apply a digital block to the affected finger.
  2. Clip off the hook’s eye above the skin’s surface.
  3. Advance the hook forward in a curvilinear fashion so that the barb protrudes through the skin again (superficially).
  4. Continue to advance through the skin until the entire hook is removed.
  5. This technique can prevent damage associated with removing the hook by retrograde traction, which would cause the barb to tear through tissue and skin on its way out.
A case study of the author's treatment of a patient with a nail through the foot is as follows:

Pearls

  • Adequate imaging that delineates the position, orientation, and depth of the foreign body is essential.
  • Achieve adequate pain control through field blocks, digital blocks, or regional nerve blocks.
  • Observe appropriate and bloodless-field techniques to safely and quickly remove the foreign body.27
  • For a successful outcome, the patient’s expectations need to be appropriate.6,5 Explain the detection and removal processes to the patient, providing the caveats that a foreign body may not be amenable to removal and that infection may occur with or without removal.
  • Always update the patient’s tetanus status, as needed.16,2,28

Complications

Complications involving soft tissue foreign bodies comprise the following:8,11,10,29,15,14

  • Inadequate or missed diagnosis of a foreign body
  • Inadequate determination of functional or neurovascular damage prior to foreign body removal
  • Removal that is inappropriate, unsuccessful, or involves additional tissue damage
  • Postprocedural retention of foreign body
  • Postprocedural or retained foreign body infections and inflammatory reaction

The patient should be informed of the potential for these complications at every step of the way. Document that the patient received this information; adequate documentation may be useful if a poor outcome occurs.15

Imaging

Radiologic evaluation of soft tissue injuries with potential soft tissue foreign bodies is often an important adjunct in evaluating and planning the potential removal of the foreign body or identifying potential nearby structures, often vascular, that may be damaged during a retrieval procedure.

The following 5 imaging modalities16 are used in foreign body removal:

  1. Conventional radiographs
  2. Fluoroscopy
  3. Computed tomography (CT)
  4. Magnetic resonance imaging (MRI)
  5. Ultrasonography

Radiograph

Radiographs are frequently the first step in foreign body evaluation. They are noninvasive, inexpensive, and can provide positional information, although not in real time, to aid in the removal of the foreign body.17,16,30 Radiographs are most useful with radiopaque foreign bodies and can demonstrate sensitivities above 95% with adequate penetration and multiple views (anteroposterior and lateral).17,16,18 Glass, which is frequently difficult to evaluate and remove, is often radiopaque even if not doped with lead. Plant-based foreign bodies, including bark or needles, plastics, and other polymers, are often radiolucent.17,19,30,18 If appropriate radiolucent surface markers are used prior to the radiograph (ie, 2 surface paperclips, one in the anteroposterior and the other in the lateral plane), positional information of the foreign body relative to the surface markers can be used if a retrieval is planned.20,21

Many authors have commented on the number and type of static views required to effectively plan foreign body removal, and many agree that at least 2 views is likely adequate in most cases. Radiographs can also provide detailed information on the potential number of foreign bodies present (and their absolute or relative sizes), which can be used by the clinician when determining appropriate irrigation, exploration techniques, and the need for postprocedure antibiotic prophylaxis. Silver nitrate is radiopaque and can serve a dual role in creating a bloodless field as well as field landmarks for radiographs taken after hemostasis is achieved.25

Fluoroscopy

Fluoroscopy has some use in foreign body removal if a C-arm or other appropriate imaging equipment is accessible.20 This technology allows for real-time radiographic visualization of the foreign body and affords the clinician the opportunity to precisely locate the foreign body using skin markers. One clinician described a technique in which, after a local field block, 2 small needles were placed and advanced into the skin at perpendicular angles under fluoroscopy until they were both touching the foreign body. An incision was then made to connect the 2 needles, and dissection (blunt) effected foreign body removal.

CT

CT has an important place as an imaging adjunct in the detection of and removal planning for soft tissue foreign bodies.17,14 CT affords the ability to visualize foreign bodies that are radiolucent on conventional radiographs. It also provides detailed information about local anatomy, tissue reactions, and abscess formation, and it can more effectively demonstrate position and orientation of the foreign body. As such, it is a rich information set for the evaluation and detection of a foreign body and for the planning of the body’s removal.

CT is easily accessible in the emergency department, is more efficient than MRI, and provides substantial information for the resources invested.23 The major drawback of CT may be that, like conventional radiographs and MRI, CT is not a dynamic modality for the emergency physician.

MRI

MRI is not used as frequently during the first clinician visit involving a foreign body. However, MRI can provide detailed information regarding tissue reactions, including chronic inflammatory reactions, osteoblastic or osteolytic changes, and secondary tissue reactions, that can aid in determining the presence and location of an otherwise occult foreign body. As an example of poor performance of MRI in the evaluation of foreign bodies, gravel particles, which are often ferromagnetic, cause significant streaking artifact on an MRI.23,13 This streaking effect does not occur on plain films, CT, fluoroscopy, or ultrasound.

The use of MRI is limited because of the adequacy of other imaging modalities and the convenience of these modalities relative to MRI. However, MRI should be considered in cases of longstanding wounds or focal infections with unknown etiology in which the presence of a foreign body is being considered.23,24

Ultrasonography

Perhaps the greatest advances in foreign body localization in soft tissue have been as a result of the move toward ubiquitous usage of diagnostic ultrasonography in the emergency department.21,25 Many authors have described bedside ultrasonography, often with the usage of the linear probe and another visualization bladder (like a glove filled with saline or tap water), to be of great benefit in locating and removing soft tissue foreign bodies.26,27,28 Ultrasonography affords the clinician real-time localization and orientation information and can also help in characterizing whether soft tissue edema or abscess is present. Since such findings are critical in both decision-making and in planning the removal of the foreign body, having them available via a convenient, dynamic bedside test is helpful.

Most reports involve real-time ultrasonography with the linear probe and require the placement of a fluid-filled bladder juxtaposed between the linear probe and the skin (with appropriate lubrication on both) to effect an adequate field of view of the entire skin and soft tissue below. Authors have also reporting using small pads on the skin to allow for transmission and improved field of view.21,25

Foreign bodies are demonstrated as hyperechoic foci with shadows that depend upon the size and composition of the foreign body. Hyperechoic halos provide evidence of soft tissue inflammation or edema but can also indicate abscess or granulation tissue.25 Because of their higher material densities, metallic or radiopaque foreign bodies often cause hyperechoic comet-tail artifacts.

Ultrasonographically based active guidance of foreign body removal is described by several authors as a technique that reduces procedural time, reduces morbidity, and improves time to detection and procedural outcomes.21,25,12 However, using ultrasonography to detect foreign bodies raises serious issues. Some reports have demonstrated sensitivity rates below 50% for gravel, metal, wood, glass, and plastic with the use of ultrasonography, although more recent reports have improved sensitivities.

The use of ultrasonography in the detection and removal of soft tissue foreign bodies in the emergency department is growing and, as more emergency departments embrace ultrasonography as a technology suited for many purposes, may become as ubiquitous as conventional radiography in the evaluation of soft tissue foreign bodies.
