# A Case Report on a Challenging Infection: Pyogenic Flexor Tenosynovitis

## TL;DR

This case report describes a rare hand infection and highlights the importance of timely diagnosis and treatment for better outcomes.

## Contribution

The paper presents a clinical case of pyogenic flexor tenosynovitis and emphasizes the need for improved diagnostic and treatment approaches.

## Key findings

- Prompt surgical drainage and antibiotherapy led to full recovery of hand mobility and sensitivity.
- Pyogenic flexor tenosynovitis remains challenging due to delayed diagnosis and poor outcomes if untreated.

## Abstract

Pyogenic flexor tenosynovitis is an infection of the flexor tendon sheaths that represents 2.5-9.4% of all hand infections. It is most commonly caused by penetrating trauma and remains a challenging problem, mostly due to the difficult diagnoses, which can lead to delays in treatment and devastating outcomes.

We present a case of a 64-year-old female patient who presented to the Emergency Department with pain and swelling of the fingers of the left hand. Urgent surgical drainage was performed. Intraoperatively, all flexor tendon sheaths were found to be affected. After surgery, she completed one month of oral antibiotherapy and underwent intensive rehabilitation. She recovered hand mobility and sensitivity completely.

Pyogenic flexor tenosynovitis is a devastating infection where outcomes depend on prompt and timely recognition and appropriate treatment. More studies are needed to find new ways to improve the preoperative diagnosis of PFT and new treatment algorithms.
