About

The goal of this prospective observational study is to assess the post-operative pain in adults with digital amputation following two different surgical interventions: microanastomosis of digital nerves or traction neurectomy. The main questions it aims to answer are:

• Which surgical intervention results in less post-operative pain?
• Which surgical intervention leads to fewer symptoms after six months?
• Which surgical intervention is associated with fewest post-operative complications? Participants will complete a Visual Analog Scale (VAS) to assess the pain and the Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) to evaluate the disabilities.

The researchers will assess post-operative complications during follow-up appointments.

Enrollment: 50 estimated patients
