Pyogenic flexor tenosynovitis
| Headline | |
|---|---|
| Etiology | Staph aureus May spread via common flexor sheaths |
| Epidemiology | |
| Clinical presentation | Kanavel's signs: - Pain on passive extension - Percussion tenderness (tenderness over entire length of flexor tendon sheath) - Symmetric finger swelling along tendon sheath - Finger held in flexion at rest |
| Pathogenesis | |
| Diagnostic investigations | Likely will have bloods at some point, but clinical diagnosis should be possible X-ray - foreign body in finger |
| Management | IV abx Would warrant I+D |
