Management of Pyogenic Flexor Tenosynovitis

Area of Science:

• Hand surgery
• Infectious disease
• Orthopedics

Background:

• Pyogenic flexor tenosynovitis (PFT) is a rare but serious infection affecting the closed spaces of the hand.
• Delayed diagnosis and treatment can lead to significant morbidity, including stiffness and contracture.

Purpose of the Study:

• To review the key diagnostic features of PFT.
• To emphasize the importance of early recognition and non-operative management.
• To differentiate PFT from other common finger infections.

Main Methods:

• Review of clinical presentation and diagnostic modalities for PFT.
• Analysis of physical examination findings in differentiating PFT.
• Evaluation of laboratory and imaging findings in PFT diagnosis.

Main Results:

• Early PFT often presents with normal systemic inflammatory markers, unlike cellulitis.
• Physical examination findings, when considered collectively, are crucial for diagnosis.
• Imaging studies (X-ray, ultrasound, CT) are not routinely used for initial PFT diagnosis.
• Antibiotic therapy alone can be curative in early, non-advanced PFT cases, avoiding surgery.

Conclusions:

• Early recognition of PFT is key to successful non-operative management with antibiotics.
• Clinical examination is paramount in diagnosing PFT, especially when compared to other finger infections.
• Hand therapy and early motion are essential for managing sequelae like stiffness and contracture.
