Overview
Infection of the tendon sheath, particularly in the flexor sheath of the hand, is a serious condition requiring urgent surgical intervention to prevent complications such as digital amputation 1.Diagnosis
Clinical signs include swelling, pain, erythema, and limited range of motion 1.
Imaging (ultrasound, MRI) may help in assessing the extent of infection 1.
Laboratory tests (white blood cell count, C-reactive protein) can support the diagnosis but are not definitive 1.Management
First-line treatment: Emergent surgical washout of the flexor sheath to irrigate and debride infected material 1.
Catheter technique: Use of a semirigid stylet conversion for catheters to facilitate passage into a septic sheath when necessary 2.
Antibiotics: Broad-spectrum antibiotics are typically initiated empirically, targeting common pathogens (e.g., Staphylococcus aureus); specific dosing not detailed in abstracts 1.Special Populations
Pediatrics: No specific details provided in the abstracts [].
Elderly: No specific considerations mentioned [].
Comorbidities: No explicit guidance given for patients with comorbidities [].Key Recommendations
Perform emergent surgical washout for flexor sheath infections to prevent digital amputation (Evidence: Strong 1).
Employ a semirigid stylet technique for catheter passage in challenging cases of septic tendon sheaths (Evidence: Moderate 2).
Initiate broad-spectrum antibiotic therapy empirically upon diagnosis (Evidence: Expert opinion 1).References
