-Assaults where an individual strikes a hard object with a closed fist (known as 'Fight Bite')
-Sports injuries or accidents involving heavy machinery


What are the typical symptoms?

-Pain and swelling in the affected area
-Inability to straighten a finger or fingers, creating a ‘drooping’ appearance
-In some cases, a visible deformity owing to tendon rupture


Which diagnostic steps are foundational?

-A thorough history and physical examination focusing on the mechanism of injury
- X-rays to evaluate for any potential bone injuries and to rule out foreign bodies
- Ultrasound may be helpful in detecting tendon pathologies


What is the standard approach to treatment?

-Non-operative treatment involving splinting and rehabilitation for minor injuries
-Surgical intervention for complete ruptures or large lacerations
-Post-operative rehab and therapy to restore function.
