The pronator quadratus muscle flap

Area of Science:

• Orthopedic surgery
• Anatomy
• Reconstructive surgery

Background:

• Distal forearm traumatic injuries pose significant challenges for soft tissue reconstruction.
• Effective soft tissue coverage is crucial for optimal functional recovery.

Purpose of the Study:

• To explore the anatomical basis of the pronator quadratus muscle for potential use as a local flap.
• To address the need for a vascularized soft tissue bed in distal forearm reconstructions.

Main Methods:

• Anatomical dissection and analysis of the pronator quadratus muscle and its vascular supply.
• Review of existing literature on forearm anatomy and flap techniques.

Main Results:

• The pronator quadratus muscle possesses a robust vascular network suitable for flap elevation.
• Its anatomical location and size are amenable to covering distal forearm defects.

Conclusions:

• The pronator quadratus muscle flap is a viable option for soft tissue coverage in distal forearm injuries.
• This anatomical study supports its potential as a local, vascularized reconstructive solution.
