Timing and Management of Suture Removal in Infected Great Toe Amputations

Infection Control and Debridement

Surgical debridement of yellow slough and necrotic tissue should be performed within 24–48 hours because these materials harbor biofilm‑forming bacteria that impede healing and increase infection risk. 1
The International Working Group on the Diabetic Foot (IWGDF) and the Infectious Diseases Society of America (IDSA) recommend early surgery (within 24–48 hours) combined with antibiotics for moderate and severe diabetic foot infections to remove infected and necrotic tissue. 1
Erythema extending more than 5 cm from the wound edge signifies active infection and warrants suture removal plus drainage before routine healing can be considered. 2
Presence of purulent drainage is a definitive sign of infection that requires immediate incision‑and‑drainage together with systemic antimicrobial therapy. 2
Systemic signs—fever > 38.5 °C, heart rate > 110 bpm, or white‑blood‑cell count > 12,000/µL—mandate operative intervention prior to any routine suture removal. 2

For soft‑tissue infection, doxycycline should be continued for 1–2 weeks; extend to 3–4 weeks if the infection is extensive, healing is slow, or the patient has severe peripheral artery disease. 1
When bone‑margin cultures are positive after a minor amputation, antibiotic therapy should be maintained for up to 3 weeks post‑amputation. 1

Sutures in toe/foot wounds must remain in place for 10–14 days after the wound demonstrates complete healing without infection, swelling, erythema, or drainage. 3
Do not remove sutures from a wound that still contains yellow slough or necrotic tissue; debridement and infection control must be achieved first, after which reassessment for suture removal can be performed. 1
If infection has not resolved after 4 weeks of appropriate therapy, re‑evaluate the patient and consider further diagnostic studies or alternative treatment strategies. 1

After suture removal in high‑tension areas such as the toe, apply adhesive strips (e.g., Steri‑Strips) to reduce the risk of dehiscence. 3
Cover the wound with a dry sterile dressing and change it every 48 hours as part of standard surgical site infection‑prevention protocols. 2
Avoid packing the wound with gauze, as this increases pain without improving healing outcomes. 2

In cases where osteomyelitis was present, monitor the patient for 6 months after completing antibiotic therapy to confirm remission. 1
