From the Guidelines

Management of a knuckle abscess involves incision and drainage as the primary treatment.

Key Considerations

  • Incision and drainage is the primary treatment for simple abscesses or boils, and antibiotics are not needed for simple abscesses 1.
  • Antibiotic therapy is recommended for abscesses associated with severe or extensive disease, rapid progression, signs and symptoms of systemic illness, associated comorbidities or immunosuppression, extremes of age, abscess in an area difficult to drain, associated septic phlebitis, or lack of response to incision and drainage alone 1.
  • For empirical coverage of CA-MRSA in outpatients with SSTI, oral antibiotic options include clindamycin, trimethoprim-sulfamethoxazole, a tetracycline (doxycycline or minocycline), and linezolid 1.
  • The choice of antibiotic should be guided by the severity of the infection, the presence of systemic signs, and the results of culture and susceptibility testing, if available 1.

Treatment Options

  • Incision and drainage: The primary treatment for simple abscesses or boils, and should be performed promptly to prevent further complications 1.
  • Antibiotic therapy: Should be considered for abscesses associated with severe or extensive disease, rapid progression, signs and symptoms of systemic illness, associated comorbidities or immunosuppression, extremes of age, abscess in an area difficult to drain, associated septic phlebitis, or lack of response to incision and drainage alone 1.
  • Empirical antibiotic options: Clindamycin, trimethoprim-sulfamethoxazole, a tetracycline (doxycycline or minocycline), and linezolid are recommended for empirical coverage of CA-MRSA in outpatients with SSTI 1.

From the Research

Management of Knuckle Abscess

  • The management of a knuckle abscess typically involves incision and drainage (I&D) 2, 3, 4, 5
  • Ultrasound can be valuable in diagnosing abscesses that are not clinically evident and in guiding I&D procedures 2
  • Packing of the abscess after I&D may not be necessary for small abscesses, and antibiotics may not always be required post-procedurally 3
  • The use of antibiotics should be considered in the presence of high-risk features, such as sepsis or cellulitis 3, 5
  • Alternative management strategies, such as needle aspiration or loop drainage, may be suitable for certain types of abscesses 2, 4

Specific Considerations

  • The size and location of the abscess, as well as the patient's overall health status, should be taken into account when determining the best course of management 4, 6, 5
  • Certain abscess localizations, such as perianal or pilonidal abscesses, may require special consideration and may have different management strategies 6, 5
  • The use of day-case surgery for the management of acute abscesses may be feasible in certain cases, with proper patient selection and management 6

Variability in Practice

  • There is significant variability in the management of cutaneous abscesses, including the use of anaesthesia, antibiotics, and packing 5
  • The development of abscess management protocols may help to guide and streamline patient management 5
