Functional Impairment

• Loss of Function: Patients may experience difficulty in flexing the affected fingers, leading to a decreased ability to perform daily activities.
• Deformity: In some cases, a visible deformity may occur, such as a "claw hand" appearance if multiple tendons are involved.

Additional Signs

• Crepitus: A sensation of grating or popping may be felt during movement of the affected fingers.
• Numbness or Tingling: If associated with nerve involvement, patients may report sensory changes in the fingers.

Diagnosis

Clinical Examination

• A thorough physical examination is crucial, focusing on the range of motion and strength of the fingers.
• Specific tests may be performed to assess tendon integrity, such as the "Bunnell test" for flexor tendon function.

Imaging Studies

• Ultrasound: Can be used to visualize tendon ruptures and assess the extent of the injury.
• MRI: May be indicated for a detailed evaluation of the soft tissue structures in complex cases.

Conclusion

Spontaneous rupture of flexor tendons in the hand, coded as M66.349, presents with acute pain, swelling, and functional limitations. Understanding the clinical signs and symptoms, along with patient characteristics, is vital for healthcare providers to ensure timely diagnosis and appropriate management. Early intervention can significantly improve outcomes and restore hand function, making awareness of this condition essential in clinical practice[3][4].
